Reviews

What customers say

Customers praise the team's clear communication, professionalism and craftsmanship. In one kitchen job, the crew minimized teardown and installation mess so the household could keep using most of the kitchen. Another customer appreciated that the crew repurposed old closet cabinets for garage and office storage.

Tommy Mina

We had Greenport do an updated island and add a bar area to our kitchen. From the initial quote all the way through final punchlist completion, the entire team was professional, friendly, and knew how to get the job done. They did their best to minimize the mess during teardown & install, which allowed us to keep using most of the kitchen during the work. Ultimately, they were clear in communication and followed through with excellent work. We're thrilled with the final product and would happily recommend them to anyone in need of some great craftsmanship!

As a designer working on a personal project, I carefully selected Greenport for the millwork, and they did not disappoint! I designed a built-in with a Murphy bed and desk, incorporating a range of finishes and integrated hardware—definitely not a simple job! Their attention to detail was exceptional, and I couldn’t be happier with the result. The craftsmanship is truly premium, and their collaborative approach made the entire process a pleasure. I've already referred them to a few friends and will continue to use them in my upcoming client projects.

Greenport Construction was fantastic to work with! We have done 3 complex renovation/reconstructions with them and have been completely satisfied with the results. Eli is amazingly knowledgable and he encourages your own preferences and visions but is so experienced that he gently states what can be easily and seasonably accomplished. I would highly recommend this group without reservations of any kind!
