Verified record
A homeowner writing in May 2024 had been told by other waterproofing companies that he needed a $10,000 sump pump. Denis came out, recommended a waterproof sealant instead, and $350 later there was no more water in the basement, even after heavy rainfall. Kenneally Foundation Waterproofing is a one-person operation on Farm Street in Bellingham, carrying a 5-star average across 32 Google ratings. The work is foundation and basement water: crack repair, leak repair, waterproofing. A 2022 customer had a large crack in a garage floor fixed; another that year had basement crack repair done and praised the quality and the honest pricing; a homeowner in 2021 had the foundation of a newly built house waterproofed and said it was finished on time. In a May 2026 review, a customer said Denis explained everything, including the products he was using, and resolved a water leak. Several customers make a point of price. One wrote in 2021 that the job turned out smaller than the photo they had sent and he lowered the quoted price; a March 2022 reviewer paired the quality with honest pricing; a February 2022 customer called the prices reasonable. Responsiveness runs alongside it — an April 2024 homeowner described a call returned right away, an estimate for a small foundation crack, a weather delay flagged ahead of time, and Denis arriving on time the day of the repair. It is worth knowing where the work stops. In an August 2024 review, a homeowner brought him a problem he could not take on, and he passed along brick mason contacts instead; that reviewer said he would call Kenneally first for anything to do with a poured concrete foundation. For a wet basement, a cracked foundation or waterproofing a new pour, this is a short call — one person quoting the job and doing the work. Get the diagnosis and the price in writing, and ask what the repair is warranted for and who to call if water comes back.

Denis is great, responsive, kind, explained everything and the products the he was using. Resolved an annoying waterleak!!!! Thanks Denis!!! Definitely recommend!!!!
Mates, can't say enough good things about this team right here. Extremely professional, personable and their work is second to none, highly recommend!!
Can’t say enough positive things about Dennis. He is clear, honest and very easy to work with. He should be your first and only call for all foundation-related needs.
Dennis is amazing. I had a problem he couldn't help me with, but he took time to discuss the problem and set me up with brick mason contacts who could! If I ever need help with a poured concrete foundation, this is the first [possibly only] company I am calling.
Great all around company. Owner is great and very responsive. Returns phone calls quickly. I highly suggest this company.
