"Greg the inspector came out, nice guy very knowledgeable, I spent 14800 in waterproofing and mold removal, new sump pump and a air purifier. Greg and I went over everything the crew was going to do. Well where the water issue I was most concerned about , they side step and only put the drain tile down the middle and not at both sides. Stay Dry ended up sending 1 person to put tile in on both sides and fixed that issue, now I am having water issue where I was not having issues before and come to find out where my water line comes in they just put gravel under and did not put the concrete back in that area. So now I have a new leak and I can't seem to get this company to come back out for a 3rd time to fix this issue. Also I have water coming up from the newly concrete floor, I was told that the concrete has to cure for awhile which I understand that, but I don't think it should be seeping up along the cracks where the new and old concrete meets. Waiting on this company to correct."

"I would highly recommend caution if you are thinking about hiring Drymaxx. We bought a new house and 4 nights later our basement flooded in a big storm. We were unable to find a local company as there was a huge number of people needing service. Drymaxx put together a team to come up from Ohio to Indiana and it seemed like such a blessing at the time. However, their work put us in a potentially terrible situation. Upon arrival the operations director put forth a plan to remove baseboards and drill holes in the drywall to ensure proper dry out. We had pulled up our carpet to collect the padding and Drymaxx did nothing to remediate it besides leaving it rolled up wet and putting a couple blowers on it. Unsurprisingly, it was still wet 4 days later and they told my wife to check with another company to see if it was salvageable. They also did not drill holes in the drywall per their plan. When my wife inquired about it specifically, they assured her it would dry out just fine. After they left my wife was able to find a local company with availability to come in a look at the carpet. They were shocked it was left like that and removed it as it was unsalvageable. They took moisture readings and found a 79% humidity reading in the main room and moisture in the drywall. They had to cut out at least a foot of drywall all around the basement. Once the drywall was off, my wife was able to see visibly wet framing in several areas. Upon contacting the operations director of Drymaxx and sending pictures, he simply expressed surprise the drywall was moist and offered no follow up whatsoever. Then we recieved a bill for $8000 with ridiculous pricing like $1000 for baseboard removal which was a one man job that might take 2-3 hrs at most. The company that cleaned up their mess did a similar amount of work and only charged $2000 for everything. Drymaxx wanted 4 times that even though they did a poor job that could have led to a serious mold problem. I contacted drymaxx several times to work out a solution but the most they would come down was to $5000. Still two and a half times what the other company charged to clean up terrible work. We are contesting the bill and would highly recommend not hiring drymaxx for your project."

We are a small contracting company that offers big results. We do have several reliable subcontractors to perform duties that we do not do in the scope of a project.
"My husband requested a quote and had to follow up with them 2 times before they even returned his call. We finally scheduled an appointment for them to come out to put together a quote for the project. The appointment was scheduled for 6:30 am and he didn't show up until almost 7 am. Said he would have a quote back to us within a week and that was the last we heard from them. My husband called them back twice to follow up and they never returned his calls."

Mold & toxic material tests FAQs
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.
