# Clark Plumbing & Heating Solutions

**Trade:** Plumbing · **Address:** 8 Rosemont Ave, Waltham, MA 02451, USA · **Phone:** (781) 547-9272 · **Website:** http://www.clarkplumbingsolutions.com/ · **Languages:** English

**Rating: 4.1/5** (medium confidence) — from 14 reviews across 5 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: 0 reviews, 0 negative.

## The honest read

Clark Plumbing & Heating Solutions is a one-man-and-a-small-crew operation out of Waltham, built around Bill Clark. The company's own website claims more than three decades in business, though its BBB profile — where it holds an A+ rating but isn't accredited — lists just 14 years; worth asking Bill directly which is accurate. What's not in dispute is the plumbing license, which the state registry verifies active.

The reviews describe a plumber who diagnoses carefully rather than guessing. In a 2022 review, a customer said Clark Plumbing was the third company called after months of inconsistent hot and cold water that two other plumbers had misread — technician Scott traced the real cause through what the customer called "a clever process" and fixed it for less than the earlier, wrong quotes. Another 2022 review made a similar point: Bill and his team, the customer said, only charge and replace what needs to be replaced, walking them through the physics of the system rather than just swapping parts.

The record also shows a willingness to go beyond a scheduled job. In a November 2025 review, Bill talked a customer through a basement injector-pump leak over the phone, free of charge, so it would be fixed before Thanksgiving guests arrived. In a 2022 review, Bill and Alex replaced a failing air-conditioner condensate pump, two valves that weren't up to code, and a leaking water heater in one visit, leaving the basement dry and the work neat. Scott, in a separate 2022 review, resolved a water-pressure problem, installed a new faucet, and swapped a garbage disposal in under two hours.

Several reviews also describe plumbing support during larger renovations — disconnecting and reconnecting a stove and sink around a kitchen remodel, including a same-day return during a snowstorm to get a customer's kitchen back in service, and detail work during a bathroom renovation to make sure fixtures worked better than before.

For plumbing work — from a diagnostic puzzle other plumbers missed to a straightforward install — the pattern here is consistent: careful diagnosis, fair billing, and technicians (Bill, Alex, Scott) reviewers name individually and say they'd call again.

**Strengths:**
- Diagnostic persistence — solved a lukewarm-water issue two other plumbers missed
- Honest pricing — replaces only what actually needs replacing
- Responsive service — free phone-guided repair before a holiday deadline

**Where sources disagree:**
- The BBB profile lists 14 years in business while the company's own website claims more than three decades of experience — the two sources disagree on tenure
