What Our Customers Say

★★★★★

"Worked with Triple Beam on having my deck replaced. Triple Beam was very transparent about the timing and stages of the project. All minor hiccups associated with these types of projects where immediately addressed. The project turned out great with really strong workmanship throughout. I highly recommend the Triple Beam team!"

Louis Szilagyi

Homeowner • Somerville, MA

★★★★★

"We had a great experience with Triple Beam. Aside from doing a great job building our deck and replacing an old basement door, what stood out was the level of communication throughout the process. They were very good at giving frequent updates on the status of the project, letting us know if the crew was not coming to our house because of bad weather, and they were quick to respond to questions we had."

Homeowner • Somerville, MA

★★★★★

"We had a great experience working with Triple Beam Carpentry in replacing two triple deckers at the rear of our condo building. Lucas and his team were readily available and finished the job on time and accurately. Lucas was transparent throughout each step of the process and constant in communicating project details and updates. Inspections and permitting were completed with professionalism. Compared with other contractors, the pricing was fair and competitive."
