Posted on Jack MartyTrustindex verifies that the original source of the review is Google. Our kitchen remodel required removing a load-bearing wall and installing a big beam, which made us pretty nervous. Coastal walked us through the whole process and coordinated the engineering without any drama. The new open layout is perfect and the finishes are exactly what we pictured. Great Project, took a while, but nothing good comes fastPosted on Crue WisemanTrustindex verifies that the original source of the review is Google. We had Coastal help with a commercial space build-out for our small business in Westerly Ri. They built new walls, installed lighting, and ran all the electrical and plumbing we needed. The work is solid and the final space works perfectly for our operations. Only reason it’s not five stars is the town inspections slowed us down significantly, but Coastal stayed on top of it… probably annoying the town and building department until answers were provided. Good teamPosted on Max HrudaTrustindex verifies that the original source of the review is Google. We converted our detached garage into a full workshop adding electrical, insulation, heating, and new doors. Coastal took care of the permitting, the framing changes, and even some drainage fixes around the building. The whole thing looks and feels like new construction. Pretty happy with how it turned out.Posted on Thomas FloydTrustindex verifies that the original source of the review is Google. Our home is over 120 years old, CCM took on a big remodel, and a lot of responsibility.. Including just over 2800 square feet of renovation + and added three rooms and an unforeseen plumbing update. Working in an old house is never easy, but they were careful not to destroy the character, but instead enhance it. . A couple of special-order materials took longer than expected, but that’s historic work for you!! Overall very professional and the craftsmanship shows.Posted on Brayden BrownTrustindex verifies that the original source of the review is Google. We hired Coastal to build a two-story addition on our Portsmouth property and honestly the work came out better than we hoped. The foundation took a while to have poured, although its a difficult time weather considered. The framing was done in under 2 weeks they wrapped up all the finishes without making it feel chaotic. Scheduling a project this size could've been overwhelming,... but they were upfront whenever something shifted. The new space feels like it’s always been part of the house.
I recently had Coastal Construction install a custom pool in my backyard, and I couldn't be happier with the results. Iain was extremely helpful throughout the process, offering valuable insights and guidance. The craftsmanship and attention to detail were top-notch. I highly recommend Coastal Construction for any construction needs.

Coastal Construction replaced my basement window wells and backfilled each window with stone. They did a great job. They worked carefully around existing shrubs and cleaned up leaving the area as it was before they started digging. They’re professional, provided excellent assessment of the job and service.

“Hi Vida and the team, just wanted to say thanks for the painting works at Holsworthy Barracks so far and your guys are great. Your site manager is all over it with regards to organizing the works, and the other guys are a pleasure to work with. The whole project team is working well together and I could not be happier. The staining of the sample toilet block really finished it off, and the client is extremely happy. The boys’ work went a long way to making an average job an awesome job. Their efforts are very much appreciated. Thank you once again!”
