"Wes and his team saved us from a terrible situation! We recently had our bathroom completely redone by a contractor who we didn't really know, and the work wasn't done well. We called in Wes, having worked with him several years ago to tile our kitchen, and he came by to take a look. Thank goodness he did! After his initial assessment, he knew right away that our "new" shower was likely leaking, and that there were multiple issues with both the tile and the structure of the shower itself. Wes coached us through buying the materials that we would need, and drew up a contract to get going on the project as soon as possible. After demolition, the problems really became apparent! All kinds of leaks, CUT FLOOR JOISTS, and other incredibly sketchy shortcuts from the original contractor. Wes walked us through the best strategy to fix everything and his team worked diligently to correct all of the issues and tile the shower beautifully. We will be working with Wes again for many more projects, particularly fixing the floor in this bathroom, which was also a hack job. He has been professional and courteous in all of our dealings with him, he shows up on time when he says he will, answers all of our questions truthfully and in depth, and he cleaned up after himself at the end of every day and at the end of the job, which is always a huge bonus! Thanks to Wes and his team for their hard work to get us the shower of our dreams, and save us from a mess further down the line."

"I moved into a 2 year old house to immediately find water seeping into the basement. I found some signs of it around the baseboard moldings. I called a couple of companies, one of them Drycrete and another, an interior french drain company. The french drain company wanted to jack hammer my finished basement and install one of their systems, an additional sump pump, and a ton of exterior work for pump discharge. That was going to cost 15-20k. Drycrete on the other hand, walked around the perimeter and noticed the obvious - foundation cracks. Those are cheap to fix, but not a guarantee. In any case, I decided to start from the top down, cracks first, 20k french drain later. The process for a crack seal is pretty straight forward and if I wasn't as pannicked I would have attempted it myself. They used Poly to inject into the crack and it worked. The basemet is dry. My sheetrock is open and the wall is still bare from the spray foam along the crack lines. I constantly measure the moisture content in the baseplates and it's slowly getting back to normal. But the moral of the story is - whatever company you bring on to a job site, whatever sperialty it is that they do, that's the solution they will likely propose to you. Drycrete did a good job as far as getting the right diagnosis. If I had to change anything about my experience with Drycrete, maybe I woould have requested for them to put up Zipwalls around the work area. Drywall and concrete dust went everywhere. Overall, good work y'all."

"What I thought was going to be a painful process turned into a pleasant experience. Mr. Flynn was very timely in giving me a quote, supplying information about the materials, paperwork such as insurance certificate , and not subbing out the job. Mr. Flynn's crew was here at 7:50 AM. Stopped for lunch at 11:30 returned to work promptly at 12:30 and was finished with the job by 3. They were all very professional and courteous. The clean up was impeccable. Mr. Flynn and his crew know how to run a business. Kudos to Robyn too for all her help. Great Company!"

FAQs for mold & toxic material test projects in Nashua, NH

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.
