"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."

"This was the 3rd time we have used Lawson and we have been very pleased each time. The first was a crawl space, the second was to remove old insulation in the attic and replace it. This time we had Lawson install a vent from a bathroom fan and install a Sanadry unit in our basement. No more moisture or musty smell! Great job every time and the men are pleasant to work with and respectful of our home. Neat and tidy work."

"We hired George to inspect our home, a new construction. He came twice, once during the pre-drywall stage and once for the final inspection. During the pre-drywall state, he brought a colleague with him who used to work in new home construction as a second set of eyes at no additional cost to us. He also conducted a radon test. Altogether, George is very knowledgeable and thorough. I followed him for the final inspection and asked about a million questions, and George always gave full, detailed answers. You can tell he values the service he provides to new homeowners and takes pride in his work."

"The vendor was punctual and very efficient.  He checked all possibilities of mold caused by the leak behind the washer.  Removed the mold and founded another problem caused by a leak in the master shower.  He also abated that problem a well.  I would not hesitate to use him again. <br />"

"The inspector Eric Riehl was very detailed, responsive, friendly, gave full explanations and helped me with the decision. The report was excellent, supplied many photos. The only problem I had was with an overly cautious statement for a crack on the base of the house. It didn't seem like a big concern during the inspection but the report was written as it was a major problem. I understand that the Company has to protect itself from liability but also people rely on the inspection to make decision and often there isn't much more time for further investigation."

"John is clearly experienced and by the end of the 3.5 hr inspection he was sweating bullets! I come to appreciate the job of a home inspector because it's so physically demanding! <br /> John produced a report that shows all the big (roof leak!) and small issues (carpet too high, prevents door from closing correctly), but what really shocked us and I will be eternally grateful for, is he got our attention on the EIFS exterior right off the beginning! We had no clue this synthetic stucco existed and that it could cause serious moisture issue for the home. He scared us and it's a very good thing. We walked away from a rather pricy home knowing that the $577.00 I spent saved me from potential serious financial mistake! <br /> In the end we ordered what John recommended, a moisture inspection, but the sellers were very uncomfortable with the invasive test and we walked away from the deal. I am heartbroken, but I am grateful and so glad I found a good inspector because h*** I would be p***** 4 months after moving in that my home had moisture problem! <br /> John we are still looking for homes, and potentially looking for a brand new construction but everything I read online said a good home inspection is still just as important on a new home as it is for a old home. So I will be calling =) <br />"

"We bought the house in 2014 and started to notice the basement was getting a little bit of water in the one corner. We attempted to fix what we thought was the problem however after heavy rain we noticed we were still getting water. We called in two basement companies, Basement Pros being the second call we made. The first call the individual used terms like "yeah that should would" and "if we do xyz you may not get water anymore"... they were not confident in their sales. They also told us we didn't have any mold to deal with. After they left we said we needed another opinion. I searched BBB and Angie's list for a company and when I came across Basement Pros we felt they had the best reviews and ratings. When I called, Helen was extremely friendly!! She was upbeat and polite and very responsive each time we talked. Pete arrived early (30mins) for our appointment which was no issue for us! I felt good with Pete's explanation of our issue, what we needed and what work would be done. He also informed us that Yes, we did have mold and what product they would use and how it would work. The day of the work the guys showed up on time (a few early but waited in their car for the foreman to arrive). They were polite, professional and hard workers!! They took the time to cover my hardwood floors (even rolled up my runners nice and neat and placed them in my other room). Donny went through everything with me and when I asked if they needed anything from me he actually asked if it was okay if they could use the restroom while they were working. I just thought it was polite they asked and not assumed. For two days these guys worked non-stopped and Donny would take me to the basement so I could see the progress they were making after each step, floor removals, piping put in, stone put down, plastic, walls covering, etc. They kept me informed throughout the process. They removed all the flooring either by hand or by buckets and placed in their truck. They removed the old sump pump and replaced it with a new one (the basin in the floor was replaced also). At the end of day they cleaned up after themselves and left no trash or scraps. These workers busted their butt and did an excellent job!!! We are very satisfied with the work and company!!"

FAQs for mold & toxic material test projects in Clayton, DE

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.
