Seacoast Water Services

Seacoast Water Services is a family-owned pool leak detection company based in West Newbury, MA, run by owner Ralph, specializing in underwater pool repairs and leak detection for residential, commercial, and municipal water systems across New England. The review record here is about as clean as they come: 47 reviews on Google spanning 2021 through mid-2026, every single one five stars, with 15 more added in just the last six months and none negative. What sets these reviews apart is the level of technical specificity — reviewers describe Ralph arriving with scuba gear, fiber-optic cameras, and specialized acoustic listening equipment, methodically working through a pool from top to bottom until he finds the source. One reviewer describes him locating a hidden pool light leak instantly with listening gear and repairing it on the spot. Another, dealing with a leak in a decades-old gunite pool for ten straight years, says Ralph found the main leak plus two others in a single visit. Several accounts describe genuinely difficult diagnostic work: one reviewer with a hard-to-pin-down leak says Ralph not only found it but identified and labeled the pool's entire plumbing layout in the process. Another says Ralph diagnosed the likely cause before even arriving on site, then sent a video afterward so the homeowner could understand the fix themselves. Communication comes up constantly as a strength — reviewers repeatedly mention clear explanations, prompt scheduling, and being kept informed throughout, and pricing is described more than once as fair. Demand for the service appears to run high: one reviewer notes appointments were typically booked out two to three weeks, though a cancellation got them seen within three days. Multiple customers describe using Ralph more than once and say he's now the person they recommend to anyone with a pool problem, including passing his number along to their own pool maintenance company. With zero negative reviews across five years and a genuinely deep bench of specific, technical accounts, Seacoast Water Services reads as a highly specialized, well-regarded choice for pool leak detection and underwater repair across the North Shore and southern New Hampshire.
