JM Carpentry works out of Hyde Park in Boston, handling the kind of jobs homeowners put off until they've read the reviews out loud — cabinet installs, quick furniture assembly, stair-rail and spindle fixes, and swapping a tired door for a solid steel replacement. The name attached to nearly every job is Jeferson Martins, who runs the business largely on his own. The strongest signal is the pattern across nine reviews collected on Thumbtack between mid-2024 and mid-2025: speed shows up again and again. One customer needed furniture assembled on short notice and had Martins on-site within 24 hours; another, working through a language barrier via Google Translate, had a steel door installed after Martins met her at Home Depot to help pick the right hardware. A kitchen-cabinet install drew praise for arriving fully prepared and handling every detail with precision, and a stair-rail and spindle repair closed with the reviewer noting the quoted price held. Sixteen Thumbtack ratings average 4.9 stars, with 94% five-star and a completed background check on file for Martins. Where the picture gets less clean is the self-reported history across directories. Thumbtack lists the business as four years old and based in Marlborough; Angi lists 28 years and Framingham; HomeAdvisor lists 18 years at the Hyde Park address that matches this profile. None of that tenure history is independently confirmed, so take any specific year count with a grain of salt — the actual review record only runs from 2024 into 2025. A single Google rating shows 1 star with no accompanying review text, an outlier against the otherwise consistent praise elsewhere. Worth confirming before booking: get a firm quote in writing, since the self-reported numbers vary so much across his online profiles. For finish-carpentry work — cabinets, trim, doors, furniture, quick repairs — the review record itself is a real, if still recent, vote of confidence.
I recently hired JM to install my new kitchen cabinets, and I am so happy with the results. From start to finish, JM was professional, responsive, and clearly knew exactly what he was doing. He came fully prepared with all the tools needed and handled every detail with precision and care. What really impressed me was his craftsmanship and efficiency. The cabinets turned out beautifully and completely transformed the space. JM was also very communicative throughout the process, making it a smooth and stress-free experience. If you’re looking for a skilled and reliable carpenter, I highly recommend JM!
I reached out on short notice for furniture assembly. He responded within minutes, showed up within 24 hours, and was fast, professional, reliable, and communicative.
I don't think I can say enough about JM carpentry. I reach out to him short noticed, he reached out back within mns. I sent him a few things I needed to assemble like asap with 24hrs period, this man showed up, showed out and got the job done may I add he's fast and professional and reliable. We communicated throughout the time he was here, he understood the assignment and delivered, I will come back with photos as I didn't take any yet but I would recommend JM carpentry a million times and I told him he will be my person to go to when I need work period please trust me do not hesitate to hire JM the best.

Jeferson did such a great job assembling a vanity and chair for me. He was very communicative, messaging me right away and came in one day. He worked quickly and even cleaned some of the marks on the furniture that they arrived with. I will certainly use again. Details: 2 items • Desk or table • Chair • Yes, I have assembly instructions or make and model information • No additional services needed (Furniture Assembly, Hired on Thumbtack)
Highly recommend Jefferson. Fixed our spindles and stair rails, helped install a door, towel handle. Very happy with his work and the price he quoted.
