"Lesson learned. Always get an estimate. BEFORE the work is done. At least a digital copy. Arrangements for the project were made, with some one named Lynn, for the company to send someone to complete the work. We were quoted over the phone 4500-5000 which included a mold test. A sub contractor with an entirely different company (National Mold Company) was sent. When the contractor arrived, he stated that the job would be much more simpler than first thought. This led us to believe that the job would cost less, no. All said and done, they charged $5500. All said and done, it's almost like no work was done. The stains and the smell are still there. Only one actual board was taken upon the attic room. The ceiling in the bedroom was primed and painted but are still visible and have a funky smell. At this point I'm going to. Do what we should have done; Do the job ourselves. Just now with $5500 less dollars in our pockets. A detailed receipt was not given even though it was requested."

-Residential home mold assessments and testing which include air, swab, and tape lift testing for mold. All samples are sent to a certified laboratory for testing. There are over 125,000 known species of mold. Don't assume! Get it tested! After the initial testing you will receive the results and a mold clean up plan on how to clean the mold if tests are positive. After the clean up I will come back for post testing to make sure the problem is solved. I also do asbestos and or mold testing after a fire or flood for the remediation experts.

"I called Adam’s Asbestos and Mold testing after we had a small fire and our contractor told us there may be an asbestos issue. Adam himself called me back within minutes, and he was at the house right away! He was professional and very detailed in his work. Best part was, that due to Adam’s report, our renovation was covered by insurance!!! Huge thank you to Adam’s Asbestos & Mold testing!"

Mold Testing and Remediation questions, answered by experts

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.

Mold, VOCs, radon, carbon monoxide, and particulate matter are typically measured.

You can do more with a home test kit than just check your water’s hardness. There are a few types of tests. The first one is simple and involves a strip that checks your water’s pH balance. The second and more thorough option is a master test kit, which shows your pH plus the presence of nitrite, ammonia, and other elements through color shades. Unsurprisingly, the most thorough test is one you send to a proper lab for analysis

Many caulk alternatives are safe for use in kitchens and food preparation areas, provided you apply them correctly and let them cure for the right amount of time. If you’re unsure about this step, call in a pro to do it for you. Silicone putty and caulk strips are often used around sinks and countertops due to their waterproof and flexible nature. Always choose products labeled as safe for kitchen use and follow the manufacturer's instructions for proper application and curing.

Figuring out why you have a musty smell in your house is the first step to getting rid of it. Mold or mildew is most likely causing the unpleasant odor. People use these terms interchangeably, but they’re actually different.

Mold is a fungus that loves to grow in moist, humid places. It’s typically black or green and has a raised, uneven texture. Stay vigilant for signs mold may be growing in your home. 

You’ll find mildew growing on your shower walls and in your bathroom’s nooks and crannies. It’s a specific type of mold that grows flat. Mildew is usually white, gray, or yellow.
