What customers said about drain cleaning
Cornel's Plumbing, Heating & Air …Kyle did a good job pressure washing out our underground gutter drains. Fast work and great communication.
CT Drains and Sewer Solutions LLCFantastic service. Scheduling was super easy and they kept me updated with the arrival time, even planning around a work call that came up. Jose was really friendly and knew exactly what to do to unclog the drain. I liked how he took the time to understand the issue, and explain things, before he got to work. Highly recommended.
Cornel's Plumbing, Heating & Air …Eric did a great job assessing our drain system and providing thorough details and recommendations. We appreciated Kyle’s work coming back out to clear the drains from our bathroom to our septic tank.

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.
