What customers said about faucet installation
Harts Plumbers, Electricians, & H…Mike was calm, knowledgable, took time to explain, able to quickly problem solve, arrived early and did not try to pull wool over my eyes. He was direct and practical without being fear based for repairs.
Price Busters Plumbing & SewerSuper professional and respectful of our home. Went above and beyond and did a great job all around. Nick and Brian were fantastic. Our estimator Sam was also very responsive with our estimates.
Taylor's Plumbing Solutions, LLCMy wife was super impressed with the crew's efficiency onsite and their conduct was professional. I'm a contrcator as well, and it's nice to know that I don't need to be around to ensure quality work takes place when Taylor's plumbing is involved.
Harts Plumbers, Electricians, & H…We invited technician to receive estimate cost for simple drop-in sink replacement together with the faucet. We were shocked to receive an estimate in the amount of $4k+ just for the labor (we already purchased the sink and faucet, plumbing service not required). I contacted many people to get their opinion and the maximum amount someone paid was $2k.
Price Busters Plumbing & SewerIan & Logan were on time, super friendly and did a fantastic job. I could not recommend them highly enough…
Price Busters Plumbing & SewerTHE PRICE WAS HIGH. WE HAD OUR OWN FAUCET TOO, IT TOOK ABOUT FOUR HOURS TO REMOVE THE OLD ONE & INTALL THE NEW ONE. WE THOUGHT IT WOULD COST ABOUT $300 OR $400 HUNDRED. EVEN WITH A $50 COUPON IT COST $770.00. THE SEVICEMAN WAS GOOD. OUR ONLY PROBLEM WAS THE PRICE.

How we grade
Satisfaction (54%) — Recency-weighted star average (2-year half-life), shrunk toward the category mean by review volume; the company’s own lifetime average as the prior; absolute: 4.0★ = 0, 5★ = 100.
Reliability (24%) — How rarely jobs go badly: share of 1–2★ reviews — 60% the last 24 months (or the 20 newest if fewer), 40% all-time; 0% = 100, 15%+ = 0; the category percentile can only raise it.
Craft & service (penalty, up to −10) — Google review highlights: Quality, Professionalism, Responsiveness, Punctuality — how rarely reviewers flag them as a negative, per review since highlights began; 0% = 100, 5%+ = 0. Subtracted from the score (up to −10), never averaged in — clean highlights are the norm, not a bonus.
Value (14%) — Customers’ own price verdicts (Great / Reasonable vs Overpriced) and Value highlights; 65% absolute (all “reasonable” ≈ 80, “great” = 100), the category percentile can only raise it.
Momentum (penalty, up to −10) — Penalises only a real slide: last-12-month average below lifetime (−0.5★ = 0). Still 4.8★+ over the last year, or steady/improving = 100. Subtracted from the score (up to −10), never averaged in.
Replies to reviews (7%) — How often the owner publicly replies to reviews under 5★ (1–4★). Needs 3+ such reviews, otherwise not counted; 65% absolute (80%+ replied = 100), the category percentile can only raise it.
