Mould Removal—Frequently Asked Questions (FAQ)

What causes mould to grow?

Mould typically enters the home as tiny spores, and when the conditions are moist, those spores are able to grow, spread, and destroy the surfaces they sit on. Mould can grow on ceiling tiles, wood, wallpaper, paint, carpet, insulation, and drywall. Although there is no way to completely eliminate all mould spores from your home, you can control their growth by keeping your home free of leaks, floods, and high humidity.

How is mould growth detected?

There are specific sites where the likelihood of mould growth is increased: basements, attic walls, insulation, ceilings, wooden joists near pipe condensation, leaking air conditioning units, broken windows or frames, foundation cracks, under-sink linoleum where there are leaks, underneath moist carpeting, under wallpaper and wall paneling, and more.

Do I need to hire a mould remediation/removal expert to remove mould, or can I do it myself?

Cutting out and cleaning mold disturbs the spores through the house, thus creating more mould issues. If you chose to remediate it yourself, you would need to build a containment using negative pressure and protective equipment. There are also additional legal rules to follow to be sure that the mould is removed. It is a much better idea to hire a professional who is well-trained and able to remove the mould with as little disturbance as possible to protect you, your family, and your home or business.

The removal process depends on how much mould is at the site, where it is growing, and what materials it is growing on. The approximate length of time to remove mould is one to five days.
