"The self-test product was as expected. The reports require additional research to interpret and understand, so seemed more targeted at professionals."

The team was hardworking, effective, and committed to the terms of the contract to get the job done!"

Mold Testing and Remediation questions, answered by experts

Mold can come back after cleaning, especially if the conditions are right. Mold loves moist environments, so if you clean a piece of furniture, then put it back in a humid area, the mold can return. Mold may also return if you missed an area during cleaning. A professional mold remediation company can help ensure that the mold is gone for good.

Yes, you can use bleach to remove mold from your aluminum siding, but it’s a powerful cleaning agent, so make sure it’s diluted with water first. A solution of one part bleach and four or five parts water works well. But it’s still a good idea to start by cleaning a small, inconspicuous area of the siding to make sure that the solution doesn’t cause damage or discoloration. 

If high moisture levels have led to mold growth on your drywall, mold remediation may be your best bet. The average cost of mold remediation is $2,400 , but the total price depends on how much you need to repair and the location. Removing mold from drywall may cost you between $300 and $825 , but the overall price could be higher if you need to fully replace several walls in your home.

Many peel-and-stick wallpapers aren’t moisture-resistant, so if you install them in high-humidity rooms, mold can grow behind the wallpaper. It’s best to reserve peel-and-stick wallpaper for bedrooms, living rooms, and other rooms with lower humidity levels. Not only does this minimize the risk of mold growth, but it also keeps the wallpaper from bubbling or peeling.

Toxic mold doesn't have a specific color; instead, toxicity depends on the type of mold and the mycotoxins it produces. Stachybotrys chartarum (also known as black mold) is notorious for its potential toxicity. However, not all molds appearing black are Stachybotrys chartarum. Mold species that appear in various colors, such as green, gray, brown, or black, can also produce mycotoxins. Therefore, it's essential to focus on identifying the type of mold through professional testing rather than relying solely on color to determine its toxicity.
