You might have wondered: What does mold remediation mean and what is involved?

Mold remediation is the term used to describe all the processes involved in eliminating harmful mold growth. It includes mold testing, removal, demolition, sanitizing, containment, and mold cleaning, depending on the type and location. A professional restoration company that understands mold growths critical nature will offer remediation to get the mold levels in your home back to a harmless point rather than a false promise of complete mold removal.

Clean Out Coffee Maker

The moist interior of a coffee maker is prime real estate for mold and mildew growth. Clean the coffee maker by using a funnel and pouring white vinegar into the maximum fill line of the water tank. Run a cycle with the vinegar . Repeat if you spot a lot of mold or mildew at the top of the tank.

Run one to two cycles of plain water to rinse the vinegar from the coffee maker before making coffee again.

Mold Remediation Safety Precautions

The process of removing mold can stir up significant amounts of mold spores. The goal of mold remediation safety precautions is two-fold:

  • Minimize the spread of mold spores through the structure.
  • Minimize worker and occupant exposure to mold spores, especially via inhalation.
  • The area affected by mold should be isolated from the rest of the structure as much as possible, using plastic sheeting or simply closing doors. However, the area should be vented to the outside if possible, using window fans or opening whatever path to the outside is available.

    Workers should wear filter masks designed to stop mold spores. Inexpensive paper masks that fit over the mouth with a rubber strap will not offer much protection. Eye protection is also important, to keep both mold spores and other debris out of the workers eyes. If possible, occupants should temporarily relocate during mold remediation to minimize their exposure, especially if they have allergies, asthma or other respiratory issues that could be aggravated by mold spore exposure.

    What A Mold Remediation Professional Will Do

    Mold remediation companies will clean up your mold in a few days if just some washing and removing carpet is involved, or in a few weeks if demolition and rebuilding is required.

    Generally, the cleanup process entails:

    • Removing water-damaged, mold-infested materials.
    • Cleaning and disinfecting walls, carpet, and personal items.
    • Removing drywall and studs if mold damage is extensive.
    • Vacuuming with HEPA filtration.

    If mold infestation is severe and you are mold-sensitive, you may have to live elsewhere during cleanup.

    Remediation costs vary depending on how much and where mold exists. Figure on:

    • $500 to $4,000 to remove mold from crawlspaces only.
    • $2,000 to $6,000 to remove mold from ducts, crawl spaces, walls, and attics.
    • $10,000 to $30,000 to repair widespread structural damage.

    Mold remediation isnt about ‘kill, kill, kill,’ says Wane A. Baker, a Wisconsin mold investigator. Even dead mold can still be allergenic.

    Do You Need Mold Removal

    Mold Removal

    If you are experiencing mold growth on your property, the answer to this question is straight and simple yes, you do.

    Nonetheless, it is important to note that removal is only a part of the process of combating mold problems. Having mentioned that, complete mold removal is impossible and mostly undesirable, the next best thing is to remediate mold.

    How To Clean Mold And Mildew From Fabric

    Avoid sending mold spores into the air and throughout the house by first taking fabric and upholstery outside when possible. Brush off as much of the mildew as possible. Then, treat fabric or upholstered pieces individually as follows.

    Moldy or mildewy fabric should be laundered in chlorine bleach and hot water. If chlorine bleach is not a safe option for the material, soak it in oxygen bleach and hot water for a half-hour, then wash as directed. Take it outside to dry in the sun if possible.

    Upholstery that you can’t take outside should be vacuumed first. Replace the vacuum bag or take the canister outside to clean. Then mix one cup of ammonia with one cup of cool water. Using a clean, white cloth, sponge the stains with the ammonia solution. Blot until all the liquid is absorbed. Repeat the process until the stain disappears. To remove the resulting ammonia solution, sponge the area with cold water and blot. Dry thoroughly with a fan or hair dryer set on cool.

    Extent Of Mould Growth

    It is important to determine the extent of the mould problem in your home to help you decide on the clean-up procedure. An area of mould is considered small if it covers one square metre or less. There should be no more than three patches of mould, with the total area staying within one square metre. Many small patches of mould in one area or throughout your home are a sign of moisture problems that need to be investigated and corrected right away.

    If ignored, small mould areas may become larger over time, so it is important to clean them up before the problem gets bigger. A small amount of mould may be cleaned up using proper procedures and protective equipment.

    The area of mould is considered medium if there are more than three patches of mould , but the total area is less than three square metres. In this case, assessment by a qualified professional is recommended but in most cases a medium amount of mould may be cleaned up using proper procedures and protective equipment .

    An area of mould is considered large if a single patch of mould is larger than three square metres. Health Canada does not recommend that an unqualified person clean up large areas of mould. You may need a professional assessment to determine why the mould is there in the first place and how to clean it up.

    Where Mold Comes From And How To Prevent It

    Mold is a fungus that releases spores into the air. Mold spores are everywhere, floating in the air and landing on surfaces. Every house and building in the world has mold spores in it, and there is no way to get rid of every mold spore in your home. So why doesnt mold grow everywhere? Mold spores need specific conditions to grow into mold: moisture and darkness. That means you can avoid mold by preventing those conditions from happening in your house.

    Mold is most common in basements, where groundwater seepage and humidity can make things damp . It is also common in bathrooms and kitchens where moisture is not properly vented. Anywhere you have a leak that is not promptly cleaned up and fixed is a good home for mold as well, whether it is a roof leak leading to mold in the attic or a plumbing leak that causes your kitchen cabinets to get moldy.

    Preventing mold requires a little work now, but you will avoid a lot of work getting rid of mold later. Here are some things to start with:

    • Fix all leaks promptly.
    • Clean up spills and dry out wet carpet.
    • Run a dehumidifier in damp areas.
    • Improve ventilation in bathrooms and in the kitchen.
    • Direct drainage away from your house to reduce basement seepage.

    Mold Removal From Fabric

    Its easier than you might think for clothes to attract mold and mildew. A forgotten load of laundry in the washing machine, the pile of clothes at the bottom of a closet, or even the armchair in a humid room can all quickly become overrun with mold. However as long as you catch the problem early, your fabrics can still be saved.

    Bleachable fabrics

    If you can apply bleach to a fabric without worrying about discoloration, do it. Thats the fastest and most effective way of getting rid of mold. Many laundry bleaches can be used on white and colorfast fabrics, although you should always check the instructions, and never use bleach on wool or silk. Simply apply a solution of one part bleach to three parts water and let it absorb into the fabric for a few minutes before laundering as usual.

    Non-bleachable fabrics

    For fabrics that cant be bleached, use white vinegar instead. Either apply white vinegar to a cotton pad and place it on top of the stain for five minutes before laundering, or briefly soak in a solution of ¼ cup vinegar to one gallon water. Rinse through to remove the vinegar and launder as normal.

    How To Remove Mold From Painted Wood

    Just because a wooden surface has been painted doesnt mean its immune to mold. Interior doors, window frames, and baseboards can all get moldy. The good news is the paint can form a protective barrier that prevents mold from getting into the wood, making cleanup faster and easier.

    Youll need:

    Paper towels

    Method:

    Step 1: Use damp paper towels to wipe away the visible mold. A soft-bristled brush will help dislodge any stubborn parts.

    Step 3: Scrub the surface gently with the soft-bristled brush to remove any remaining stains. Wipe clean with paper towels.

    Step 4: Combine one part white vinegar with one part 3 percent hydrogen peroxide in a spray bottle and spritz the surface. Do not soak the wood, just get it damp. Allow to air dry.

Vinegar and peroxide will prevent it from returning, but make sure to address the underlying cause. Painted wood isnt molds first choice for a home, so its likely theres an issue with damp in that area.

    Hvac Or Air Duct Mold Treatment Cost

    The average cost for HVAC mold treatment is between $450 and $6,000 because ventilation systems require special cleaning. Mold grows from moisture in the air ducts from hot and cold air condensing in the vents. Because mold spores become airborne, youll need to turn off your HVAC system once mold is discovered, so you dont spread it through the home.

    You may need to replace all the hard surface air ducts and any infected insulation. Replacing air ducts and vents cost$270 to $500 per duct or $25 to $55 per linear foot to install. Add an additional $1 to $8 per square foot of surface for insulation.

    Calculate The Extent Of The Mold Contamination

    Mold may not always grow in one area, so you need to figure out how much contamination you’re really looking at. Calculating the extent of the contamination will impact how you approach mold removal and clean up. The goal of mold removal is to clean up mold growing within the home, and to avoid exposing homeowners to large amounts of mold.

    The New York City Department of Health has developed guidelines for cleaning up mold contamination. These guidelines are widely used in the construction industry and recommend six levels of mold removal based on the square footage of the mold and whether or not the mold is located within the home’s HVAC system. Following the NYC DOH’s guidelines, available online, calculate the remediation level needed.

    Bathroom Mold Removal Cost

    Bathrooms are usually not well ventilated, and moisture and mold can collect in the shower and bathtub, sink, and drains. Typically, bathroom mold removal costs $500 to $1,500.

If there’s some mold in the shower or elsewhere in the bathroom that seems to reappear, increasing ventilation and cleaning more frequently will usually prevent mold from recurring, or at least keep the mold to a minimum.Environmental Protection Agency

    How To Clean Mold From Wood

    Mold loves wooden surfaces. Whether its your window sills, flooring, wall framing, or furniture, the high cellulose content of wood provides mold with lots of food. Because wood is also very absorbent, its easy to create a perfect environment for mold with very little moisture. If you do find mold growing on wood in your house, heres how to get rid of it.

    Youll need:

    100-grit sandpaper

    Method:

    Step 1: Begin by vacuuming up as much of the mold as possible using a vacuum with a HEPA filter. You can also use a soft-bristled brush to dislodge the mold and make this easier. Remember to wear a dust mask to prevent breathing in mold spores while you do this.

    Step 2: Add a teaspoon of soap to two cups of water in a spray bottle. Shake to combine and spray the mold and surrounding surface.

    Step 3: Use a soft-bristled brush to scrub away the mold and mildew. Use paper towels to soak up any excess water.

    Step 4: To kill the roots, add 1 tablespoon of borax to a cup of water and use a soft-bristled brush to apply the solution to the area. Allow it to absorb into the wood.

    Step 5: Run a fan or dehumidifier in the room to quickly dry the wood.

    Step 6: If the mold is very stubborn, use 100-grit sandpaper to remove the affected area.

    Pro Tip: Is the wood still stained? This is usually a result of mildew the discoloration mold leaves behind. While bleach doesnt kill mildew, it can help remove the stains. Try scrubbing a small area with a dilute bleach solution.
