"Basement Doctor work crews were prompt and polite, accommodated my requests, and cleaned up beyond my expectations. There were, however, significant problems. Estimate was incomplete -- need for dehumidifier was not emphasized until after the work was in progress so was not in the contract. Cement dust was bad enough to injure my lung. However, Basement Doctor made what seemed like reasonable effort to contain the dust. The same might have happened no matter who did the work. After phase one was done, there was dampness along the crawlspace wall where drainage had been installed. I was told that it was not wet. In order for it to be wet, there had to be standing water. When examining the conditions in order make an estimate for phase 2, my project manager looked at the crawlspace drainage that had been installed in phase 1, he saw something that caused him to call the production manager, then told me that there was a problem with the drainpipe as installed in phase 1 and that it would be replaced in phase 2. This left me with worry about whether the rest of the work had been done correctly. When phase 2 was complete, I expressed disappointment that the appearance of the encapsulation did not live up to expectations. Primarily, the taped joint between the material used on the floor and part way up the wall and the silver insulated material used on the was not level, and was wavy to an unsightly extent The white material billowed out from the wall into the floor space rather than going down the wall consistently then out onto the floor. The project manager said that Basement Doctor guaranteed the function of the work, not its appearance. The foreman said that the white material would, over time conform to the wall. (It hasn't.) The project manager said the production manager (director?) would call me. It took three months and a nasty letter from me for that call to be received. When he came to my home the production manager reiterated that Basement Doctor stood behind the function of their work, not its appearance -- at least for the type of work done in my home. He said that there had been no problem with the drainage pipe that had been replaced, but that it had been replaced at my request. At that point I wondered who I should believe. He did improve the appearance of the encapsulation by adding tape so the joint was no longer wavy."

FAQs for mold & toxic material test projects in Newark, OH

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.
