What customers said about septic system installation
Busy Bee Septic and Excavating LLCOn time, described everything in detail, worked fast and did not leave a mess. Amazing will continue my service with them moving forward!
Dawes Septic and RepairDawes recently replaced the septic tank at our house. The whole team was very professional and friendly, including Becky, Carl, and CJ. While it took some time to get a site visit, it was definitely worth going with Dawes for this work — they clearly take pride in what they do, and the work went without a hitch.…
United Sewer and SepticUnited Sewer is my go to for all my septic and sewer needs. They're courteous and on time. Thank you!
Enviro-CleanTechnician was very polite and went beyond the service he was rendering. Felt very comfortable doing business with this representative.
Wind River Environmental of Beaco…Flavio was great he was efficient and the ultimate professional. I highly recommend him and Wind River
Busy Bee Septic and Excavating LLCBusy Bee pumped our septic tank and installed risers so we could access the tank in the future without digging up the ground each time. Dwayne in particular was very kind, knowledgeable, and professional - we'll definitely use Busy Bee again in the future for our septic maintenance/service.

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.
