"After moving into my home, I realized water was coming into my basement. I had three companies come out to provide estimates to waterproof the basement. Allstate's salesperson, Mitch, was very, very personable, knowledgeable and I felt like he really listened to me during the estimate process. Mitch brought pictures with him to show me as well as the company's certifications. Allstate's price was in the middle of the pack of three estimates. Mitch's preparedness was what won me over. Allstate came to my home to install a French drain (along two walls of the basement) and install a sump pump. The workers arrived promptly at 8am, had the containment up in the basement, and were jack hammering by 8:20. About midway through the project, Mitch stopped by to check and see how things were going. As previously stated, I don't have any complaints about the workers what-so-ever. They even stopped worked twice so I could come down to the basement to take pictures of water and mold damage. For the water intrusion and mold in my basement to have been such a traumatic experience, Allstate certainly made the nightmare better than bearable."

"During the past month (June 2012) I was involved in an unrelated mold remediation job in which the testing was extensive and exceedingly expensive. I have been searching around for other testing options that would satisfy a first screening process to get a handle on the types of mold and levels of concentration. Envirohealth proved to fit the bill for this service very well, and I will certainly use this testing in the future as needed, and offer a solid recommendation here."

"Carl was excellent to work with. While the concrete work was technically outside his company's scope, he worked with a local concrete expert that was also excellent. All work was performed in a professional and timely manner. All construction materials were cleaned up and removed from our property. All work was performed as agreed with no subsequent price adjustments. I'd gladly use them again."

"Dean provided my complimentary basement inspection which consisted of looking for water entry points, foundation and floor cracks, and all potential other water challenges in the basement. He spent about 20 minutes walking me through each point of the Inspection and explaining to me the purpose what he was looking for and why. At the end of the complimentary inspection, Dean confirmed no further action would be necessary. Dean was professional, knowledgeable and polite; never pushy and very honest. I would highly recommend Thompson's Basement Waterproofing's free inspection to anyone concerned about your basement. Thompson's obviously is only interested in selling their products to people who need them; not taking advantage of Homeowner's who don't have the subject matter expertise needed to properly assess this type of situation. Thanks Thompson's! <br />"

"It went great. First, the sales person was very helpful explaining the mold testing and remediation process. He went through the steps that would be taken and then he followed up with the results. On the french drain,/sump pump change out/ wall rebuild, it was quick and painless. Again my sales person was very clear in the process and the steps. When he came for a walk through there were some options in what would occur in the installation and he made fully aware of any potential changes in cost (there were none though). The workers came on time (ok a bit early) and finished early as well. Finally, they were helpful and clear walking through all the changes that occurred and the guarantees given."

FAQs for mold & toxic material test projects in Northumberland, PA

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.
