What Is A Mold Remediation
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:
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.

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.

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.

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.
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.
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.
Step 1: Use damp paper towels to wipe away the visible mold. A soft-bristled brush will help dislodge any stubborn parts.
Step 2: Make a solution of 1 teaspoon dish soap to 2 cups water and use the spray bottle to apply it to the wood.
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.

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

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.
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.
