Verified record
Kenneally Foundation Waterproofing is Dennis's own foundation crack and leak repair business out of Bellingham, and the word that comes up again and again across 16 reviews isn't 'fast' or 'cheap' — it's honest. The clearest example: a homeowner had been told by other waterproofing companies they'd need a $10,000 sump pump system; Dennis came out, recommended a waterproof sealant instead, and the fix held through heavy rainfall for $350, in a 2024 review. Another customer says Dennis showed up, found the job smaller than the photos suggested, and lowered his quote on the spot, in a 2021 review. When a job fell outside his specialty, he didn't take it anyway — he connected the homeowner with brick mason contacts who could help, in a 2024 review. The jobs themselves run from small foundation cracks to a leak described as 'quite large,' with reviewers consistently mentioning that Dennis explains what he's doing and why before and after the repair. The written record runs from 2021 through mid-2026 with no negative reviews on file — every one of the 16 is five stars, including one in 2026. One thing worth knowing: the Better Business Bureau's profile for the business shows a file opened in March 2026 and describes it as in business less than six months, which sits oddly against a five-year written review history — likely a newer formal BBB registration rather than a new business, but worth asking about directly. For a foundation crack or basement leak, Kenneally's record — and its price-conscious, straight-talk reputation — makes it an easy first call.

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.
