"They have 2 ladies that came and cleaned out the air ducts. They were very professional and cleaned up and dust from the cleaning. Recommend them to a lady down the street and she ended up using them for her dryer. Definitely using them again went we refinish our wood floors in our main house."

"Jeremiah was amazing with customer service. Attentive, always responded. Lamar was the technician. I just didn’t feel like he had a lot of experience but he was here quite awhile, inside and outside the home. Jeremiah said they charged $299 and no mileage fee, but did not mention that the two tests to see if it was black mold would be $700! That was upsetting but you were stuck because you had paid $300 for him to come out. It took a while to get tests back but that wasn't their fault. Just wish we hadn't been blindsided, but otherwise very reliable."

"We'll see if it makes a noticeable difference in our well-being, but our peace of mind has definitely been improved by the vent cleaning. Highly recommend Air Specialties for the job. They showed up on time, worked their a**** off, got up into the attic and cleaned the actual trunk lines, took a lot of videos and pictures to show their results, and eliminated a lot of mold and dirt residue. Very professional, friendly, and they only do one job per day to make sure they take as long as it needs to do a thorough job."

"Extremely prompt to answer questions or concerns. Service technician was "right on time" for the initial testing. I was lucky to have no asbestos so I cannot review their removal process. I was impressed with the office staff's communications."

FAQs for mold & toxic material test projects in Knoxville, TN

Some companies offer a no‑cost phone or video consultation that screens for red flags. If the discussion points to a real issue, the pro will recommend a paid on‑site inspection. The complimentary call clarifies whether you need full testing, but it isn’t a substitute for samples, lab work, or a written report. Always confirm what the free service covers before you schedule.

A standard inspection, which includes basic air and surface samples, takes an average of two hours. If the pro needs to probe hidden spaces, such as wall cavities or ductwork, plan on up to six hours. Extra time allows the inspector to reach tight areas, collect additional samples, and document findings. Lab analysis is a separate process and often adds several business days to the overall timeframe before you receive the full report.

Mold thrives where moisture lingers and air flow is poor. Common hotspots include bathroom walls, kitchen backsplashes, window sills, HVAC vents, fireplaces, crawl spaces, and enclosed attics. Check these areas regularly—especially after leaks or high‑humidity weather—to catch growth early and avoid costly repairs.

Unchecked mold can knock 20% to 37% off a home’s market value because buyers worry about hidden damage and health risks. Even after remediation, visible staining or a history of major moisture issues can still lower offers and prolong the time on the market. Addressing mold quickly protects both your property’s structural integrity and its resale appeal.
