DryZone Basement Systems is a Bridgewater basement waterproofing company, and one recent customer's account shows the work: MJ, AB and the crew installed TrenchDrains, an UltraSump, an exterior discharge line, a wall system and waterguard over two days, and left the basement spotless. The company describes itself as an authorized Basement Systems dealer working across Massachusetts and Rhode Island on waterproofing, crawl space encapsulation, foundation repair and sump pumps. Its Massachusetts home improvement contractor registration, number 160052, is active on the state registry. On Google it holds 4.9 stars from 536 ratings, Angi shows 4.8 stars from 97, and its BBB page carries an A+ grade with accreditation since 2008. A recent customer who got 4 inches of water when a standard sump failed to kick on said Nick walked them through a TripleSafe sump system, and that Kervin and his crew worked all day on the install, after which he showed them how everything works. A recent customer had the exit of a sump pump relocated about 50 feet away and said Michael explained everything and that the top layer of the yard was saved to cover the trench for the new pipe. A recent customer had a sump pump and dehumidifier put in and the entire crawl space insulated, with Marcellus as production foreman. A recent customer with a 113-year-old house on a fieldstone foundation, where previous owners had buried garbage and there was so much water, had the basement done by Kervin Reyes and his team. A recent customer said they have requested Curtis Bess for their annual inspection for many years. A 2026 customer said Michael Gilmore came to service a 20-year-old Sanidry unit, explained the options, and found a potential fire hazard while servicing the pump, which he replaced under warranty. A Reddit commenter in r/WorcesterMA said a 3-pump system with French drains came to about $14,000 for their home, much cheaper than they expected. A recent customer who hired DryZone to clean out a crawlspace and upgrade its vapor barrier said the crew laid the new barrier over the existing dirt, debris and old vapor barrier without cleaning, and that the project manager promised for day two was on site for about 20 minutes. That customer also said the crew spray-foamed rodent bait stations into the side of the house, and that after firing them they lost the entire $6,000 deposit. A recent customer said the company did not call back or follow up with initial appointments after repeated calls. A 2023 customer said the company's policy was not to email the proposal, and that the verbal quote on site was $20,000.
“I used Dryzone Basement Systems. It was much cheaper than I expected for a 3-pump system with French drains, came out to about $14,000 for my home.”
Worst Contractor Experience Ever – Avoid DryZone Basement Systems / All Things Basementy I had the single most egregious contractor experience of my life with DryZone Basement Systems (the local All Things Basementy provider) on my Massachusetts property. I hired them to clean out my crawlspace, which had an older vapor barrier, and upgrade it to a new vapor barrier system. Their sales pitch and materials specifically promised that the space would be thoroughly cleaned before any new material was installed. On the first day the crew began laying the new vapor barrier directly over the existing dirt, debris, and old vapor barrier without cleaning anything. I immediately stopped the project and contacted management to request a different crew that would actually do the job properly. Management convinced me to give them another chance and promised they would send a project manager to be on site the whole day on day two while the crew cleaned. What actually happened is that the project manager was only there for about 20 minutes. While the crew was supposedly cleaning out the old material, they only cleaned a small section and then covered up all the remaining old debris and old vapor barrier with the new material — doing exactly what I had already complained about on day one and had been assured would not happen. To make matters worse, the crew spray-foamed rodent bait stations directly into the side of my house. It was obvious this was done deliberately and in a retaliatory, vindictive manner after I had complained and stopped their work. At that point I fired them. I lost my entire $6,000 deposit and had to hire another crew to rip out everything they had done. The cost to remove their improper work and start over was more than the original contract amount. I ultimately had the crawlspace properly cleaned and the vapor barrier upgrade completed correctly through the Mass Save program. This company showed zero respect for the homeowner’s instructions, broke their promises about oversight, and acted dishonestly even after management got involved. I told them in no uncertain terms that they would never be allowed back on my property again. Strong recommendation: Do not use DryZone Basement Systems or any All Things Basementy contractor under any circumstances. They charge double the competition (or more) while promising quality but delivering substandard work. If you need crawlspace cleaning, vapor barrier upgrade, or encapsulation work, hire a dedicated cleanup/restoration crew separately (Servpro or equivalent) to get the space truly clean and ready, then have the new vapor barrier installed through Mass Save or a reputable local contractor. You will save yourself an enormous amount of money and avoid massive frustration. This was by far the worst contractor experience I have ever had. Learn from my mistake.
MJ (Marcellus), AB and the crew just finished up waterproofing our basement. They installed TrenchDrains, UltraSump, an exterior discharge line, wall system and waterguard. The job was done meticulously in two days. The basement was left spotless. The system was explained thoroughly. MJ and AB were thoughtful and accommodating throughout the install. That is what customer service is all about. Thank you!
Excellent job. Very professional! Kept work area orderly and clean.
Very satisfied with the whole project outcome. The guys who did the work were extremely efficient, professional, and hard working. Would not hesitate to refer them.
We are very happy with our new sump pump install. Tomas Ajanel Pol and his “1st Stop” team were great - professional and friendly, worked quickly, and left everything just as tidy as when they arrived. This gives us peace of mind.
