"For the homeowners who discovered mold in their home, and are stressed and worried about the potential cost of the eradication process, you need not look any further than these guys! Craig showed up promptly on the day day and time of our appointment, and my wife and I were immediately impressed and comfortable with his warmth and knowledge! During his assessment, he took his time pointing out the obvious areas and certain problems we never noticed! He did this not to frighten or pressure us, but being informative about the reason for for the presence of the mold! But what shocked us was the total cost of eradication...it was almost half of what 2 other companies had quoted us! His crew of young men worked tirelessly and were friendly and courteous to a fault. No complaints about their cleanup efforts either! We would highly recommend this company in a heartbeat! Ray & Lisa Jones, Delaware, Ohio"

Mold Testing and Remediation questions, answered by experts

Checking for mold yourself is crucial, as catching mold in the early stages is ideal. Mold can appear green, brown, black, blue, or yellow. It can smell musty and can feel like velvet, leather, or cotton. 

Most often, mold grows near water damage. It’s best to inspect these places for signs of mold growth:

  • Basement: Look in corners, windows, carpet, closets, and around appliances. 

  • Bathrooms: Check around sinks, ceilings, and around toilets. 

  • Kitchen: Inspect around the sink, behind the refrigerator, and behind trash can.

  • Attic: Look near the insulation and near intake and exhaust vents.

Mold thrives in wet or moist conditions, so a fridge water dispenser can be the perfect place for them to live. You may transfer mold to the dispenser's nozzle by touching it with the rim of an unwashed water bottle or your hands. 

If you see splotches that look like mold, you can clean them using vinegar. Distilled white vinegar is acidic enough to kill and remove most mold species.

It can be challenging to know if mold is growing behind walls without knocking them down. If the walls show signs of water damage (discoloration, water stains, or peeling paint) or there’s a musty odor, it’s possible mold is growing. Know the difference between signs of water damage vs. termites because termite infestations are sometimes mistaken for water damage. A more subtle sign might be your own health: If you’re constantly not feeling well or are sneezing, scratching your eyes, or coughing when in a specific room, you could have mold.

If you believe mold is hidden somewhere in your home, don’t delay inspecting it, as it can be dangerous, especially to people with breathing problems and allergies. While it’s possible to learn how to check for mold yourself, we advise most people to hire a professional mold inspector, who can look more thoroughly. You can also purchase mold test kits if you aren’t sure if your home has mold, but a true human inspector is still your best bet.

You can do a basic home water test, but we recommend having a pro conduct a more in-depth test. This method is accurate, and you’ll have a pro who knows your house helping you determine a plan of attack for anything out of the ordinary.
