**Rating: 3.8/5** (medium confidence) — from 16 reviews across 4 sources. A 0–5 star rating built from what customers and the public say (every review and mention weighted by where it was posted, how old, how detailed and how credible it is, shrunk toward a 3.5★ baseline when evidence is thin) plus what the record shows (Reddit recommendations or warnings, a registry-verified licence, how recently they were reviewed, customer work photos, BBB grade, negative news, a revoked licence). Positive record counts only as far as the reviews have earned it; penalties count in full. Confidence describes how much weighted evidence stands behind the number, never the number itself: low when fewer than about five normal reviews' worth of weight (or mentions only) support it, medium up to about twenty, high beyond that across at least two sources. An operator flag for a suspicious review pattern caps a rating at 3.5★ and marks it low.
100% of sentiment-scored reviews read net-positive. Last 6 months: 1 reviews, 0 negative.

## The honest read

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.

**Strengths:**
- Honest pricing — recommended a $350 fix over a $10k sump pump
- Fair quotes — lowered price when job was smaller than expected
- Honest referrals — sends outside-specialty jobs to other trades
- Explains the work — walks through the repair before and after

**Where sources disagree:**
- BBB profile lists the business as open less than 6 months (filed 3/25/2026), while the review record runs back to 2021
