No heat on a frigid Wednesday night: a 2026 customer said Jacob from Coastline Plumbing and Mechanical came to the call that night and replaced the part on their boiler, then came again the same night when a second issue popped up. That 2026 customer said he also followed up with a phone call early the next morning to check on the heat overnight. The company's website lists a service area of ten towns, from Westport, Fall River and New Bedford to Newport and Bristol, and offers free estimates. It holds a 5-star average from 11 Google ratings. Its Massachusetts plumbing license, number 3529-PL-C, is active on the state registry, held by Coastline Plumbing & Mechanical LLC. One customer said a heating system was installed by Coastline 7 years ago and has since hired them for many small service calls, a complete bathroom remodel, and rough and finish for a new construction addition. A customer who got a new boiler said the job was quoted and done within a week, and that they reached back out afterward to make sure the water temperature was to that customer's liking. One customer said John came in on a last-minute call and worked all weekend until everything was finished. A customer thanked Jonathan and said they arrive immediately every time that customer calls. In a 2025 review, a customer said Coastline installed a whole home water filter neatly and on time, and that there was no more brown water.
Great work and reasonable price. Highly recommend
John was great and reliable. I called him last minute needing work done ASAP. He came in and worked all weekend until everything was finished. Would definitely recommend to anyone
Coastline Plumbing is an excellent company with outstanding customer service! Every time I call, they arrive immediately, and their rates are always very reasonable. A huge thank you to Jonathan for the great service—I really appreciate the hard work!
Excellent workmanship and service. I first had a heating system installed by Coastline 7 years ago. They did a great job, they were clean, and good communicators. I have since hired them to do many small service calls, a complete bathroom remodel, as well as rough and finish for a new construction addition. I would never use anyone else. Professional family business, that never settles for good enough. Always perfection.
Easy to get in touch with. Calls/texts are answered promptly. Work area is always cleaned up. Very reasonable prices.
