What customers said about sprinkler system inspection
Castle Sprinkler & Alarm, Inc.I had a leakage of the sprinkler in the kitchen. The technician who's name was Hector was sent to fix it. Hector is very professional, pleasant and patient even though it was late in the evening. He left after he made sure that everything was working.
Castle Sprinkler & Alarm, Inc.Unreliable and unacceptable business practice and monitoring service company. CSA charged our company to monitor 2 panels but in fact only 1 panel was being monitored. Additionally, their emergency service is non-existent. Had to call a 3rd party vendor to assist with a damaged sprinkler head which CSA previously installed incorrectly.

How we grade

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.
