    Using Hydrogen Peroxide For Mold Removal - October 6, 2019 by admin

    Hydrogen Peroxide has been used as a very simple and effective cleanser in our households for long. However, when it comes to mold removal at home, it can also become your best companion and make sure that the walls in your house dont look bad. Molds are generally responsible for releasing a few toxic chemicals that might cause sneezing and allergy-like symptoms to the members of your household. Therefore, when only a small area of the house gets infected, using hydrogen peroxide can be a great way to get rid of the molds without having to spend hundreds of dollars on professional mold removal. Bellow we describe the method of removing mold with hydrogen peroxide, but if you want a safe and non-toxic/eco friendy cleaner we would recommend the mold removal products from our shop.

    Hydrogen Peroxide For Mold Removal

    It is important to understand that there is a difference between the commercially available bleach and the hydrogen peroxide we use at home. Bleach is generally harsher on the walls. Though peroxide can also result in the fading of the wall colors and must be diluted with water in order to be used safely, it is normally better than the use of bleach. It is easily available in the house. More importantly, you would not have to bear fumes and smells that are characteristic of bleach usage on the walls.

    The first thing that you have to do here is to ensure your safety. Though hydrogen peroxide is safer, there is absolutely no harm in taking precautions to safeguard yourself. Wear gloves and breathing masks so that you remain safe. These mask and gloves will also protect you from getting infected by the mold when you are cleaning them from the walls. Therefore, you need to be very careful. Dilute the peroxide now. Ideally, the concentration should be only 25% with water which means that 3 parts water must be mixed with 1 part peroxide for better results. This would remove any chances of fading colors of the walls while still killing the mold.

    Pour the solution into a spray bottle and then apply it thoroughly on the walls. Let the solution sit for at least 10-15 minutes, so that the chemicals get time to kill all the colonies of mold. After this is done, use a brush with very hard bristles to remove even the lightest debris on the walls. If there is any stain or debris left on the wall, then you would probably see new colonies in a very small time. Take your time in this process. Now, use some warm water to clean the walls and finally use paper towels or cleaning cloths to dry off the walls.

    Mold Remediation in Cars – Seatco - October 6, 2019 by admin

    Lets talk about something exciting today mold remediation in cars. Or, as most people call it, mold removal in cars. If youre like me, then you have no idea how often mold occurs in our automobiles, that is, enough mold so that you have to take it somewhere and have the car cleaned and treated.

    I thought these instances were quite rare, and pretty much limited to instances where a car was flooded, or, left outside during a two-day rainstorm with all the windows down.

    But, after talking with Neal Ailstock, owner of Seatco, about mold remediation in cars, he states that Seatco sees around 10 vehicles a month come in for mold remediation, and most of those jobs happen because a sunroof drain or a drain attached to the AC system or some other drain in the car gets blocked, and water being water, it seeks someplace else to go. That location is almost always within the interior cabin.

    Carpets and seats get wet, its a closed environment so the interior cant dry out quickly, and mold occurs. It smells bad, and sometimes its enough mold so that it makes people sick.

    The vehicle shows up at Seatco, and the guys here go to work.

    This is what usually happens when Seatco performs mold remediation in cars:

    Sometimes, one of these steps needs to be repeated, and sometimes the sequence is juggled a little bit, but this is the usual process.

    Of course, as all this is happening, other technicians diagnose the cause of the leak and repair same.

    How long does this take?

    Anywhere from 3-7 days, depending on the drying time needed. For example, if its the middle of the hot summer, and its not raining, everything dries much more quickly.

    And the big question, how much does all this cost?

    The average is around $1200. Could be less, could be more, but the average is around $1200.

    And thats it. The customer drives out of here with a dry, fresh-smelling car, the mold has been banished, and everyone breathes a bit easier.

This is why our technicians with 911 Restoration are licensed, insured, bonded, certified, and prepared for any challenge that arises in your home or business.

    Sewage backups are ranked based on category, from one being clean water hazards to three which involves deadly pathogens capable of seriously harming human health.

    If you come home to a sewage backup, contact our sewage backup cleanup restoration specialists with 911 Restoration today!

    Mold typically plagues homes that were subject to recent water damage. When a home floods, it does so in a variety of ways, from the initial damages that the water causes, to the erosion of support structures, and eventually, mold growth. This is why our technicians arrive as quickly as possible with all the tools and techniques needed to give you and your home a Fresh Start with a free visual inspection and professional mold removal.

    Mold spores, especially black mold, can take hold in any location where there is a minimum amount of moisture and a substrate for them to germinate. This means that virtually any surface that remains wet for too long will be a harbor for mold and fungus contamination.

    Many people dont realize that mold spores are actually around them at all times. This is why our technicians bring such sophisticated air scrubbers and dehumidifiers to each job. By utilizing the most advanced technology such as vapor barriers, moisture readers, and even infrared technology, our specialists can find, stop, and destroy mold growth no matter where it is.

    When it comes to fire and smoke damages for homes and businesses, 911 Restorations technicians are experts at both eliminating the fire effects, and the ancillary damages. Fires require our professionals to remove smoke from the vents, odor from the air, and soot from the walls.

    Most of the time a fire damage situation is localized to a certain section of the home, but because many buildings have air ducts and ventilation systems that run throughout the property, the smoke and soot from a fire event can travel anywhere. When soot and smoke invades the air ducts, even a fire localized to one room can coat the entire home with a layer of potentially harmful dust. This patina may have signatures of everything from irradiated particulate to noxious chemicals that can be cancerous or poisonous if inhaled or ingested.

    It is crucial that, after a fire, the restoration efforts are handled by highly trained experts. If your home has recently been through a fire, then you need to contact our specialists with 911 Restoration immediately for help.

    Our technicians with 911 Restoration mobilize with all the tools, equipment, supplies, materials, and techniques they need to provide your home or business with immediate assistance no matter what form the disaster takes.

    Our technicians know how to perform the most sophisticated water extractions, deepest smoke removal, and toughest mold remediation jobs. We are also highly adept at giving fundamental advice to protect houses and businesses against natural disasters in your area. Preventing disasters is far more cost effective than repairing the damages that can result from them, so dont hesitate to contact our specialists for any advice you need for your home or business.

    Ultimately when homes and businesses have a full scale disaster situation to deal with, the furniture, office equipment, and personal belongings need to be removed to avoid further damage and contamination. Since a complete restoration takes place all at once, we offer moving and storage options for all types of belongings when these events take place.

    Additionally, when it comes to a disaster, quick action tends to be the best recourse for preventing small challenges from becoming larger ones.

    Is a Landlord Always Responsible for Mold Remediation? - October 6, 2019 by admin

    Mold is a bit like gluten some people are more sensitive to it than others, and those that are sensitive can be almost religious in their avoidance.

    If you have a tenant with mold sensitivities who alerts you to a mold problem, the appropriate response may not be obvious.

    You may think that its your responsibility to clean it up, but many times, its not. It depends on the severity and cause of the problem.

    On one hand, its impracticalto mount an expensive remediation project for a problem that may exist more in imagination than reality. On the other hand, failure to respond to a genuinely hazardous condition could result in significant discomfort for a sensitive individual, and it could also result in a lawsuit.

    Mold is a controversial health issue. Savvy landlords take it seriously, but they dont overreact.

    As of January 2016, there was no federal lawsetting permissible limits or tolerance standards on mold in residential building, and only six states California, Indiana, Maryland, Virginia, New Jersey and Texas had passed laws regulating mold levels in indoor environments. In Virginia, the law expressly requires the landlord to:

    maintain the premises in such a condition as to prevent the accumulation of moisture and the growth of mold, and to promptly respond to any notices from a tenant as provided in subdivision.

    While the other 50 states dont specifically legislatemold, theydo require the landlord to disclose potentially hazardous conditions at the time of rental, and theyalso require landlords to correct conditions that make a dwelling uninhabitable. Toxic mold is arguably one of those conditions.

    Some municipalities have laws that clearly define the landlords responsibilities.

    According to the Centers for Disease Control and Prevention, there may be as many as 300,000 varieties of mold on our planet, and many are benign. Some, such as Penicillium, are even beneficial.

    Because they are virtually everywhere, however, it may be impossible to take a breath without inhaling some type of mold spore, and most people do so without consequence. Sensitive individuals, however, can experience respiratory irritation, aggravated asthma symptoms, headaches and other ailments, especially when certain strains are present. The two most problematic are:

    Stachybotrys chartarum

    Aspergillus

    There is no guarantee that either of these species are growing in any particular mold colony, but testing for them would require detailed inspection with a microscope and is usually impractical. Consequently, any mold colony growing in a dark, wet place in a dwelling unit is suspect, and its difficult to claim that toxic strains are absent and that a particular colony is harmless.

    Its clear that any mold that results from a plumbing or structural leak should be addressed by the landlord as part of the repair. But should a landlord feel compelled to respond to amold problem caused by unsanitary domestic habits? Probably not.

    Landlords arent required to provide cleaning services, and to insist ondoing so would constitutean invasion of privacy. For example, it would be reasonable to expect a tenant to clean up a mold colony growing in a corner in which he or she habitually throws damp towels.

    Between these two extremes, however, are many gray areas. For example, mold often grows inside drains that habitually clog. Aclogged drain is usually caused by what goes in the drain, not the drain itself. Or consider that moldmay grow in a poorly ventilated crawl space, but the lack of ventilation may be due to piles of stored belongings.

    Here are some industry standards on the responsibility of mold remediation, but please know that each county, or Judge, might view this differently.

    The ideal landlord/tenant relationship includes good communication and a commitmentto work together to maintain quality of life.

    In the end, that shared commitment is the key to health and wellbeing for everyone.

    Chris has owned and managed 4 rental properties in Santa Cruz, CA, and Salida, CO. He is a DIY handyman expert for popular sites like Pro Referral.

    Mold Remediation Guidelines – Environmental Health and Safety - September 29, 2019 by admin

    Concern about indoor exposure to mold has been increasing as the public becomes aware that exposure to mold can cause a variety of health effects and symptoms, including allergic reactions. This document presents guidelines for the remediation/cleanup of mold and moisture problems in facilities at NC State University including measures designed to protect the health of building occupants and remediators.

    Mold can be found almost anywhere; it can grow on virtually any organic substance, as long as moisture and oxygen are present. There is mold that can grow on wood, paper, carpet, foods, and insulation. When excessive moisture accumulates in buildings or on building materials, mold growth will often occur, particularly if the moisture problem remains undiscovered or unaddressed. It is impossible to eliminate all mold and mold spores in the indoor environment. However, mold growth can be controlled indoors by controlling moisture indoors. Request an Indoor Air Quality assessment

    Since mold requires water to grow, it is important to prevent moisture problems in buildings. Moisture problems can have many causes, including uncontrolled humidity. Some moisture problems in buildings have been linked to changes in building construction practices during the 1970s, 80s, and 90s. Some of these changes have resulted in buildings that are tightly sealed, but may lack adequate ventilation, potentially leading to moisture buildup. Building materials, such as drywall, may not allow moisture to escape easily. Moisture problems may include roof leaks, landscaping or gutters that direct water into or under the building, and unvented combustion appliances. Delayed maintenance or insufficient maintenance are also associated with moisture problems in schools and large buildings. Moisture problems in portable classrooms and other temporary structures have frequently been associated with mold problems.

    In some cases, indoor mold growth may not be obvious. It is possible that mold may be growing on hidden surfaces, such as the backside of dry wall, wallpaper, or paneling, the top of ceiling tiles, the underside of carpets and pads, etc. Possible locations of hidden mold can include pipe chases and utility tunnels (with leaking or condensing pipes), walls behind furniture (where condensation forms), condensate drain pans inside air handling units, porous thermal or acoustic liners inside ductwork, or roof materials above ceiling tiles (due to roof leaks or insufficient insulation).

    Some building materials, such as dry wall with vinyl wallpaper over it or wood paneling, may act as vapor barriers, trapping moisture underneath their surfaces and thereby providing a moist environment where mold can grow. You may suspect hidden mold if a building smells moldy, but you cannot see the source, or if you know there has been water damage and building occupants are reporting health problems. Investigating hidden mold problems may be difficult and will require caution when the investigation involves disturbing potential sites of mold growthmake sure to use PPE.

    For example, removal of wallpaper can lead to a massive release of spores from mold growing on the underside of the paper. If you discover hidden mold, you should revise your remediation plan to account for the total area affected by mold growth.

    Assess the size of the mold or moisture problem and the type of damaged materials before planning the remediation work.

    The decision to relocate occupants should consider the size and type of the area affected by mold growth, the type and extent of health effects reported by the occupants, the potential health risks that could be associated with debris, and the amount of disruption likely to be caused by remediation activities. If possible, remediation activities should be scheduled during off-hours when building occupants are less likely to be affected.

    Remediation

    If you are unsure what to do, or if the item is expensive or of sentimental value, you may wish to consult a specialist. Specialists in furniture repair/restoration, painting, art restoration and conservation, carpet and rug cleaning, water damage, and fire/water restoration are commonly listed in phone books. Be sure to ask for and check references; look for affiliation with professional organizations. Molds Can Damage Building Materials and Furnishings

    A variety of mold cleanup methods are available for remediating damage to building materials and furnishings caused by moisture control problems and mold growth. The specific method or group of methods used will depend on the type of material affected. Please note that professional remediators may use some methods not covered in these guidelines;absence of a method in the guidelines does not necessarily mean that it is not useful.

    Method 1: Wet Vacuum

    Wet vacuums are vacuum cleaners designed to collect water. They can be used to remove water from floors, carpets, and hard surfaces where water has accumulated. They should not be used to vacuum porous materials, such as gypsum board. They should be used only when materials are still wetwet vacuums may spread spores if sufficient liquid is not present. The tanks, hoses, and attachments of these vacuums should be thoroughly cleaned and dried after use since mold and mold spores may stick to the surfaces.

    Method 2: Damp Wipe

    Whether dead or alive, mold is allergenic, and some molds may be toxic. Mold can generally be removed from nonporous (hard) surfaces by wiping or scrubbing with water, or water and detergent. It is important to dry these surfaces quickly and thoroughly to discourage further mold growth. Instructions for cleaning surfaces, as listed on product labels, should always be read and followed. Porous materials that are wet and have mold growing on them may have to be discarded. Since molds will infiltrate porous substances and grow on or fill in empty spaces or crevices, the mold can be difficult or impossible to remove completely.

    Method 3: HEPA Vacuum

    HEPA (High-Efficiency Particulate Air) vacuums are recommended for final cleanup of remediation areas after materials have been thoroughly dried and contaminated materials removed. HEPA vacuums are also recommended for cleanup of dust that may have settled on surfaces outside the remediation area. Care must be taken to assure that the filter is properly seated in the vacuum so that all the air must pass through the filter. When changing the vacuum filter, remediators should wear PPE to prevent exposure to the mold that has been captured. The filter and contents of the HEPA vacuum must be disposed of in well-sealed plastic bags.

    Method 4: Discard

    Remove Damaged Materials and Seal in Plastic Bags

    Building materials and furnishings that are contaminated with mold growth and are not salvageable should be double-bagged using 6-mil polyethylene sheeting. These materials can then usually be discarded as ordinary construction waste. It is important to package mold contaminated materials in sealed bags before removal from the containment area to minimize the dispersion of mold spores throughout the building. Large items that have heavy mold growth should be covered with polyethylene sheeting and sealed with duct tape before they are removed from the containment area.

    Always use gloves and eye protection when cleaning up mold!

    If the remediation job disturbs mold and mold spores become airborne, then the risk of respiratory exposure goes up. Actions that are likely to stir up mold include: breakup of moldy porous materials such as wallboard; invasive procedures used to examine or remediate mold growth in a wall cavity; actively stripping or peeling wallpaper to remove it; and using fans to dry items.

    The primary function of Personal Protective Equipment (PPE) is to avoid inhaling mold and mold spores and to avoid mold contact with the skin or eyes.

    Gloves are required to protect the skin from contact with mold allergens (and in some cases mold toxins) and from potentially irritating cleaning solutions. Long gloves that extend to the middle of the forearm are recommended. The glove material should be selected based on the type of materials being handled. If you are using a biocide (such as chlorine bleach) or a strong cleaning solution, you should select gloves made from natural rubber, neoprene, nitrile, polyurethane,or PVC. If you are using a mild detergent or plain water, ordinary household rubber gloves may be used. To protect your eyes, use properly fitted goggles or a full-face respirator with HEPA filter. Goggles must be designed to prevent the entry of dust and small particles. Safety glasses or goggles with open vent holes are not acceptable.

    Respirators protect cleanup workers from inhaling airborne mold, mold spores, and dust.

    Minimum : When cleaning up a small area affected by mold, you should use an N-95 respirator. This device covers the nose and mouth, will filter out 95% of the particulates in the air, and is available in most hardware stores.

    Limited : Limited PPE includes use of a half-face or full-face air purifying respirator (APR) equipped with a HEPA filter cartridge. These respirators contain both inhalation and exhalation valves that filter the air and ensure that it is free of mold particles. Note that half face APRs do not provide eye protection. In addition, the HEPA filters do not remove vapors or gases. You should always use respirators approved by the National Institute for Occupational Safety and Health (see Resources List).

    Full : In situations in which high levels of airborne dust or mold spores are likely or when intense or long-term exposures are expected (e.g., the cleanup of large areas of contamination), a full-face, powered air purifying respirator (PAPR) is recommended. Full-face PAPRs use a blower to force air through a HEPA filter. The HEPA-filtered air is supplied to a mask that covers the entire face or a hood that covers the entire head. The positive pressure within the hood prevents unfiltered air from entering through penetrations or gaps. Individuals must be trained to use their respirators before they begin remediation. The use of these respirators must be in compliance with OSHA regulations .

    Disposable clothing is recommended during a medium or large remediation project to prevent the transfer and spread of mold to clothing and to eliminate skin contact with mold.

    Limited : Disposable paper overalls can be used.

    Full : Mold-impervious disposable head and foot coverings, and a body suit made of a breathable material, such as TYVEK, should be used. All gaps, such as those around ankles and wrists, should be sealed (many remediators use duct tape to seal clothing).

    The purpose of containment during remediation activities is to limit release of mold into the air and surroundings, in order to minimize the exposure of remediators and building occupants to mold . Mold and moldy debris should not be allowed to spread to areas in the building beyond the contaminated site.

    In general, the size of the area helps determine the level of containment. However, a heavy growth of mold in a relatively small area could release more spores than a lighter growth of mold in a relatively large area. Choice of containment should be based on professional judgment. The primary object of containment should be to prevent occupant and remediator exposure to mold.

    Limited Containment

    Limited containment is generally recommended for areas involving between 10 and 100 square feet (ft 2 ) of mold contamination. The enclosure around the moldy area should consist of a single layer of 6- mil, fire-retardant polyethylene sheeting. The containment should have a slit entry and covering flap on the outside of the containment area.

    For small areas, the polyethylene sheeting can be affixed to floors and ceilings with duct tape.

    For larger areas, a steel or wooden stud frame can be erected and polyethylene sheeting attached to it.

    All supply and air vents, doors, chases, and risers within the containment area must be sealed with polyethylene sheeting to minimize the migration of contaminants to other parts of the building. Heavy mold growth on ceiling tiles may impact HVAC systems if the space above the ceiling is used as a return air plenum. In this case, containment should be installed from the floor to the ceiling deck, and the filters in the air handling units serving the affected area may have to be replaced once remediation is finished.

    The containment area must be maintained under negative pressure relative to surrounding areas. This will ensure that contaminated air does not flow into adjacent areas. This can be done with a HEPA-filtered fan unit exhausted outside of the building. For small, easily contained areas, an exhaust fan ducted to the outdoors can also be used. The surfaces of all objects removed from the containment area should be remediated/cleaned prior to removal

    Moisture Control is the Key to Mold Control

    Full Containment

    Full containment is recommended for the cleanup of mold contaminated surface areas greater than 100 ft 2 or in any situation in which it appears likely that the occupant space would be further contaminated without full containment. Double layers of polyethylene should be used to create a barrier between the moldy area and other parts of the building. A decontamination chamber or airlock should be constructed for entry into and exit from the remediation area. The entryways to the airlock from the outside and from the airlock to the main containment area should consist of a slit entry with covering flaps on the outside surface of each slit entry. The chamber should be large enough to hold a waste container and allow a person to put on and remove PPE. All contaminated PPE, except respirators, should be placed in a sealed bag while in this chamber.

    Respirators should be worn until remediators are outside the decontamination chamber. PPE must be worn throughout the final stages of HEPA vacuuming and damp-wiping of the contained area. PPE must also be worn during HEPA vacuum filter changes or cleanup of the HEPA vacuum.
