How To Handle Mold In Your House

Where To Check For Mold In Your Kitchen

How to handle mold in your home

From long-forgotten leftovers in the back of your fridge to the not so easily forgotten dishes that pile up in the sink, there are ample surfaces for mold to take up residence in your kitchen. The added levels of humidity from using the stove and running hot water from the sink can cause kitchen mold to grow quickly. Some of the most common places to check for mold in the kitchen include:

Dealing With Mold In Walls

Before beginning the job of removing mold from the inside of walls, you need to cover doorways, air vents, and other openings to other parts of the home with plastic. If youre working in a large room, you can use large sheets of plastic to block off a smaller area in which you will be working. This prevents the spread of mold spores to other areas of the home. Mold remediation experts often recommend setting up negative pressure in the work area, as well.

Remove moldy drywall and insulation. Use a spray bottle of water to dampen moldy materials before removing them this helps prevent mold spores from becoming airborne during the process. When sawing through moldy drywall, you can have an assistant hold a vacuum hose with a HEPA filter nearby to further decrease the spread of mold spores. Enclose moldy materials in heavy plastic garbage bags before carrying it out of the home so no mold spores are spread to other areas of the home in the process. Its imperative that you do everything possible to prevent spreading mold spores throughout the house so that you dont end up with mold in other rooms.

Moisture: Investigating And Solving Problems

Mould will grow indoors if moisture is present. Moisture problems in homes may result from:

  • daily activities such as showering or bathing, washing clothes or cooking, if exhaust fans are not working properly or are not used
  • infiltration of water from the outside when there are cracks or leaks in the foundation, floor, walls or roof
  • plumbing leaks
  • moisture condensation on cold surfaces
  • flooding due to weather conditions
  • inadequate ventilation.

Moisture indoors accumulates when it cannot be vented outside and becomes a problem when building materials become damp or wet.

Moisture problems are preventable.

Unless the cause of the moisture problem has been identified and solved, mould will reappear. Once the moisture problem and its causes have been identified, they must be fixed. To prevent future problems, measures should be put in place to control sources of moisture in your home, for example:

  • Ensure rain, irrigation water and snowmelt drain away from the house by sloping the grade away from the building.
  • Keep eavestroughs and downspouts clean of debris and ensure that the outflow runs away from the house and not into neighbouring foundations.
  • Repair plumbing leaks promptly.
  • Use exhaust fans, ventilation and air conditioning systems to vent moisture outdoors.
  • Use moisture tolerant materials in areas likely to get wet .

Run a dehumidifier in damp areas such as basements or if you observe that moisture is condensing on cold surfaces such as window panes.

Remove Mold From Drywall/painted Walls

Mold can often grow on drywall and painted interior walls, especially in areas where moisture and humidity are a factor, such as kitchens and bathrooms. Walls can also be affected if your roof or exterior walls are infiltrated by water. If the drywall remains wet, mold can begin to grow and penetrate the drywall throughout. When this happens, the drywall must be removed and replaced, as you will not be able to get rid of all mold under these circumstances.

Where Does Mold Originate

Mold growth often begins in a high moisture area, such as standing water outside the shower or leaky windows. Once a source is identified, it should be fixed promptly and all the excess moisture removed, said Kimble. While many say bleach can handle a mold cleanup, it destroys the plant life itself but it waters the spore, or the seed, with moisture, which allows it to survive, he said.

Bleach may work on non-porous surfaces such as glass, metal or plastic, but not on porous surfaces like wood, concrete or drywall, where mold could easily seep into the material and stay alive, said Nardozzi.

Types Of Mould To Look Out For In The Home

Not all mould is created equal. So, when tackling mould growth in your home, its a good idea to know what youre dealing with especially as each type of mould has its own set of characteristics, growth patterns and health effects to take into consideration.

Being aware of where mould grows in home can help you stop the problem at its source and prevent you from going through the same mould, same mould process of locating and treating it. Here are some common household moulds to keep an eye out for.

Air Conditioning And Heating Vents

You probably prefer your bedroom to be at the optimal temperature for you to get a good nights rest. While using the AC and heating unit are fine , its possible for mold to grow in the vents.

To prevent mold from contaminating your bedroom, you should:

  • Use a dehumidifier to remove excess moisture from the air
  • Dry up any condensation you find on the walls and windows
  • Invest in a mold-resistant mattress or, at the very least, a waterproof mattress cover

How to Deal With Mold in Your Home

The key to removing moldy materials is containment and thoroughness. Seal off the area. Create a crude air lock door to contain spores and dust by covering the opening with a sheet of poly slit in the center, then cover that with another sheet or flap. Wear a respirator and work slowly and surely. Double-bag or wrap all materials, then wash all remaining hard surfaces with a 1/2 percent bleach solution and let dry.

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 ΒΌ cup vinegar to one gallon water. Rinse through to remove the vinegar and launder as normal.

The Diy Mold Testing Process

While home mold testing kits are simple to use, they only capture samples in the air and on exposed surfaces. They arent intended to detect mold inside walls, but they can provide a starting point for DIY mold removal.

A top-of-the-line home mold testing kit should include:

Growth medium that serves as a base for tested samples Petri dish for passively catching airborne spores Sterilized swabs to collect visible samples directly from surfaces Sample bags for shipping suspected mold to testing labs

Once you send off your sample, turnaround time can vary from five business days to three weeks. Also, be aware that the cost for mail-in analysis is usually in addition to your original mold kit purchase price.

What Is Black Mold

Black mold is often found inside houses with excessive moisture damage to wallboard and other surfaces. Much is made of this type of molds toxicity but the mold itself isnt harmful.

How To Get Rid Of Mold In Walls

If the wall is made from a non-porous surface, such as finished wood or stone, it must be thoroughly dried. A dehumidifier, proper ventilation or a wet vacuum can be used. Then, a damp wipe down of the area should remove most of the mold. Cleaning products designed for mold removal are helpful, however it is not necessary to bleach moldy areas or use other biocides. If the wall is made from a porous material such as gypsum drywall, wallpaper or unfinished wood, it is not possible to remove all of the mold from the tiny nooks and holes in the wall. The affected section of the wall must be cut out and replaced. This can be very expensive. However, the mold will almost certainly come back otherwise.

Finish the mold removal by using a vacuum with a HEPA filter. A non-HEPA vacuum may not contain the mold spores and can actually spread them into the air. Vacuum the entire area and surrounding areas, even if no mold is visible.

Do not just paint or caulk over mold without removing it. According to the EPA, this will cause the paint to flake and peel, and when the paint comes off, you will still have mold on the wall.

Remember That Professionals Have Tools That You Dont

How to deal with mold in your home

According to Jeff Miller, a real estate agent with AE Home Group in Maryland, More often than not, the mold is either from a small plumbing leak or from a roof leak, so fix that first. If the mold is located under a bathroom or kitchen sink where there could be a plumbing leak, call a plumber to investigate. Similarly, he recommends having a roofer inspect and seal any gaps in the roof if you see thats the cause of the mold.

Miller recommends having the mold remediated by a professional. They have access to the proper chemicals you need to ensure no mold residue after treatment, and they can test your home to ensure that the mold hasnt spread.

Kyle Rowley, mold remediation expert at Restoration 1 in Waco, TX, agrees. He says that mold can be tricky and dangerous. Even if there has been no water damage to a property, mold can come from something as simple as a leaky window because moisture and mold go hand-in-hand.

And because mold can cause so many problems, he says homeowners shouldnt take any chances. Having mold present can lead to allergens, irritants, mycotoxins, sneezing, breathing problems and long-term diseases, Rowley says.

Removing Mold From Different Rooms

Some rooms are more prone to mold than others. Bathrooms are notorious for mold growth because they harbor damp, humid environments that mold loves. Less frequented rooms such as basements and attics can also suffer from mold, which can go unchecked for a long time before being noticed. Heres how to prevent mold from taking hold in each room of your property.

How Do Molds Affect People

Exposure to damp and moldy environments may cause a variety of health effects, or none at all. Some people are sensitive to molds. For these people, exposure to molds can lead to symptoms such as stuffy nose, wheezing, and red or itchy eyes, or skin. Some people, such as those with allergies to molds or with asthma, may have more intense reactions. Severe reactions may occur among workers exposed to large amounts of molds in occupational settings, such as farmers working around moldy hay. Severe reactions may include fever and shortness of breath.

In 2004 the Institute of Medicine found there was sufficient evidence to link indoor exposure to mold with upper respiratory tract symptoms, cough, and wheeze in otherwise healthy people with asthma symptoms in people with asthma and with hypersensitivity pneumonitis in individuals susceptible to that immune-mediated condition.

In 2009, the World Health Organization issued additional guidance, the WHO Guidelines for Indoor Air Quality: Dampness and Mould pdf iconexternal icon pdf icon. Other recent studies have suggested a potential link of early mold exposure to development of asthma in some children, particularly among children who may be genetically susceptible to asthma development, and that selected interventions that improve housing conditions can reduce morbidity from asthma and respiratory allergies.

Limit Your Exposure To Mold

Its important to limit your exposure to mold and mold spores. Keep them out of your eyes and try not to inhale any.

  • Wear a mask or an N-95 respirator to avoid inhaling mold.
  • Wear gloves that extend to the middle of your forearm. If youre just using water and a mild detergent, household rubber gloves work fine.
  • Wear goggles that dont have ventilation holes to avoid getting mold or spores in your eyes.
