"Dave was super helpful and steered me toward the real solution I needed -- not testing but direct remediation of a leaking window and wall. His experience really helped get the job done and to calm my nerves after I discovered the leak!"

"Rick, the owner of Ovation put us instantly at ease. His suggestions led us to not only remodel our bathroom, but extend remodeling to the rest of our home. Our first meeting, and every interaction following with Rick's crew was positive. They came, they worked hard, always smiling and were very flexible towards our needs. We heard how much they thought of Rick and his wife Jessica, which only confirmed we made the right choice. Issues came up, which we didn't count on, and I'm embarrassed to admit Rick & Jessica were on the receiving end of my stress, but despite this, Rick always remained patient, and even Jessica called to reassure me she was working on it. In the end, my whole house was completely made over with new bathroom cabinets (including linen storage) flooring, doors, trim, molding and paint. The quality of our remodel has turned our home into an amazing staycation. We hope to have Rick & Jessica over for dinner, not only because Rick is a was, but because we want to show our gratitude"

Mold Testing and Remediation FAQs, answered by experts

Nearly all homes have at least some airborne mold spores. If you want to determine the concentration of spores in the air, you have a few options. The most effective option is to hire a professional tester who can take air samples of the home. The tester would send the samples to a laboratory to determine the concentration of mold spores. 

Mold is a fungus that typically grows in warm, moist environments, which is why it's so often found in bathrooms, attics, and under sinks. It survives by digesting decaying organic materials, which makes it very helpful for removing dead plant matter around the world. However, if it starts eating away at your drywall, window frames, and flooring, it can harm your home and your health.

Knowing what to expect during a mold inspection can help make the process easier. Prepare by closing doors and windows for 48 hours, turning off HVAC systems for at least two hours, and avoiding disinfectant chemicals for at least 48 hours. 

The mold inspection process takes between 24 and 48 hours. Your professional will check walls, fireplaces, air ducts, vents, and windows for visible spores. They will also take an outdoor base air sample. Your pro will send these samples to a lab for testing and advise you on the findings.

If you would like the insurance company to potentially help you pay for the mold remediation, you need to inform the insurer. When you notify your insurance company, they may say that you need a mold inspection before receiving any money for mold remediation. It’s possible that the insurer would not pay for this inspection unless they find mold.

Yes, mold can easily grow under your hardwood floors, especially if your house has recently flooded or if there is a leak from a pipe under the floor. Hardwood floors can trap moisture beneath them, creating the perfect environment for mold to grow. Similarly, mold can also grow under your wood floor’s surface paint.
