Coastal Irrigation

Coastal Irrigation is a Mashpee-based irrigation contractor working across Cape Cod, hired to install residential sprinkler systems and then to keep them running season after season — spring openings, in-season repairs and fall winterization. Its Google page carries a 5-star average from 651 ratings, and 453 written reviews are on file from 2017 through 2026 across five sources, so this is a deep and continuously active record rather than a thin one. What customers praise is remarkably consistent: technicians who arrive on time or early, diagnose the problem quickly and finish in one visit. Reviewers name individual techs — Alex, Will, Genaro, Derek, Wayne — and credit them for explaining the system rather than just fixing it: walking a new homeowner through every element of an inherited system, adjusting run times by zone, installing a rain gauge on the spot. A June 2026 reviewer wrote that the company kept in contact, showed up when it said it would and charged the estimated price, contrasting that with other irrigation firms that quoted and never followed up. The work described spans the full lifecycle: new installs (a 2024 reviewer described sprinkler heads fitted around a yard full of gardens and a pool), replacing outdated heads, recalibrating timers, adding drip lines and wireless controllers, and routine spring turn-on and fall winterization. In a 2023 review, a four-year customer described a seasonal program with a spring turn-on, a July mid-season check and a fall shut-off. The one thing worth asking about before booking is office communication. A 2-star Google review from October 2024 came from a customer whose original installation had gone well but who then went years unable to get calls or emails returned, and who found the office contact unpleasant when they did get through. Most reviewers report the opposite — texts before arrival, easy scheduling, prompt callbacks — so ask how scheduling and follow-up are handled and get a named contact for your account. Neighbours recommend them locally too: Nextdoor posters in South Yarmouth and Marstons Mills named Coastal Irrigation in April 2025 when neighbours asked. The recent record is unbroken — 47 reviews in the last six months with no negatives — though many of those are short and generic, so weigh the detailed accounts above the one-line ones.
