Two design professionals wrote reviews for L Squared Construction, and both of them bring Jeff in on their own clients' work. A kitchen designer wrote in March 2025 that they count on L Squared whenever a general contractor or cabinet installer is needed, and described Jeff and Angela as professional, courteous and fairly priced. An interior designer, writing in June 2024 about custom plans for a master closet, said his practical suggestions made the project better than imagined and that his team kept materials arriving on time. L Squared is a husband-and-wife business in Sagamore Beach — Jeff and Angela — that says the two of them bring 25-plus years of combined experience to kitchen and bath remodeling, interior and exterior trim, siding, flooring and house additions, working Bourne and Buzzards Bay out through Falmouth, Mashpee, Barnstable and Dennis. Twelve Google reviews run from June 2024 to April 2025, behind a 5★ average across 13 ratings. What those homeowners hired him for spans more than one trade. A June 2024 reviewer had Jeff build a new deck and back stairs, and noted he repaired areas that had been put together badly 40 years earlier. Another June 2024 review lists a roof replacement with a new skylight, every window replaced, three doors, a barn door, an outside railing and a microwave installed. An April 2025 review credits him with an addition on a small house and calls him a perfectionist about his work. Punctuality and cleanup come up in several of the 2024 reviews — showed up when scheduled, worked straight through to the finish, picked up before leaving. Several reviewers also mention cost: one wrote that his estimate came in below the other companies they looked at, another that he worked with them to keep costs reasonable. If your Cape project touches several trades at once — an addition, a deck, windows and the interior finish work after — this is the kind of contractor built for it. Before booking, get the scope and schedule in writing, confirm the home improvement contractor registration and insurance, and ask for a reference from a job close to yours.
Typical Greater Boston range for this kind of work, from regional averages — not a quote from L Squared Construction. Use it to sanity-check bids, then get the real number in writing.

Excellent experience! Jeff is a perfectionist when it comes to his work. I will call him again! Beautiful addition added to my small house. He’s the best!
As a kitchen designer who is always in need of a great GC or cabinet installer I can always count on L Squared Construction. Jeff and Angela are always professional, courteous, and offer quality craftsmanship at a fair price. Thank you L Squared for all that you do for us at Mahoney's!!
Excellent craftsmanship. Very polite and professional.
The job was well done. Jeff was prompt, personable, worked straight thru until the job was finished & cleaned up after himself. I'm happy with the results.
Jeff did a beautiful job creating a new deck and back stairs on our home. He also repaired areas that were not constructed properly 40 years ago when the old stairs and decking were built. His estimates were below other companies we looked at. I highly recommend him for any carpentry work you want done to your specifications.
