Groundworks describes itself as a national provider of foundation repair, basement waterproofing, crawl space encapsulation, and concrete lifting, operating in the Boston area partly through acquired regional brands including Busy Dog and Rescon. Many written reviews from 2025-2026 describe detailed, positive installation and inspection work: waterproofing systems, crawl space encapsulation, sump pump installation, foundation column stabilization, and basement drain work on homes over 50 and 100 years old, with individually named technicians repeatedly praised for clear communication and thoroughness. Worth asking about before booking: a December 2024 review describes an open Better Business Bureau complaint and a state Attorney General investigation into an improperly installed moisture barrier that was coming apart. A June 2026 review describes over $8,000 in mold, mildew, and water damage remediation traced to a French drain and sump pump system the company (then operating as Busy Dog) had installed before the reviewer bought the home. A separate June 2026 review describes a year-long delay on a signed, financed contract for a beam repair, with no work performed until the customer cancelled. Several other reviews from 2024-2025 describe no return calls after initial contact, and one 2024 review describes an installed sump pump as non-functional. Given these dated, specific concerns — including a regulatory investigation — alongside the genuinely strong individual installation reviews, homeowners should ask directly about warranty terms, follow-up support, and the status of any open regulatory complaints before signing a contract.
Busy Dog (now Groundworks) installed the French drain and sump pump system in my basement before I purchased my home. During a recent renovation, we discovered mold, mildew, water damage, and a missing vapor barrier behind a finished basement wall, resulting in over $8,000 in remediation and reconstruction costs that insurance would not cover. After raising these concerns, Groundworks provided a complimentary inspection but then proposed a $6,581.43 upgrade and service contract instead of addressing the significant damage and questions surrounding the original installation. During that same visit, the technician also damaged my sump pit cover. I'm still waiting for meaningful accountability and a response from management.
Footing expansion work. The office doesn't organize efficiently, but the final work was delivered nicely. Special thanks to Guiles Hall, Jason Lewis and Keven Bristo.
Poor service. I signed a contract with your branch office in plainville Mass in July 2025 and pay a financed down payment of $3,900.00 to come and fix rooted beam in my property they didn’t show up until I canceled the contract in June 2026. They waisted my time for one year and refused to refund my down payment with interest. Especially, Zach stein, the Sales Manager; he never responded to my email, also, Steven the field Salesman is a scammer.Please public be aware of this company that they are scammers and stay away from them. They posted flashy advertisements but that is not what they represent. Thank you. Signed by - Moses Olatunde
Justin Reyes was the lead contractor at our project. Not only was he incredibly responsive and efficient but he was able to get the work that was needed to be done in a very timely fashion. Justin was very thorough with his explanations and always available for questions. He was such a pleasure to work with and very happy we chose Groundworks because of their excellent customer service and efficiency. Thank you Justin!
I usually don’t leave reviews often, but Waterproofing team truly exceeded my expectations. From the initial consultation to the completion of the work, the entire process was smooth and professional. The team arrived on time, carefully inspected the issue, and explained the waterproofing process in a way that was easy to understand without trying to upsell unnecessary services. What impressed me the most was their attention to detail and cleanliness throughout the project. They treated the property with respect, kept communication clear, and completed the work within the promised timeline. After dealing with recurring moisture issues for a long time, it’s a huge relief finally having confidence that the problem has been properly fixed. It’s hard to find contractors who are reliable, honest, and genuinely committed to quality work, but this company definitely delivered. I would absolutely recommend this Waterproofing team to anyone looking for dependable basement or foundation waterproofing services.
