M&M Carpentry & Masonry, run out of Lynn by Mynor (spelled Maynor and Mauro in different reviews), covers the kind of mixed exterior and structural work a lot of contractors won't take on in one job — deck rebuilds, stair construction, masonry repairs, trim carpentry, and siding fixes. In a 2025 review, one homeowner describes the crew handling a garage rebuild that mixed masonry and carpentry from the ground up, and in a 2022 review, another describes M&M repairing wind-torn aluminum flashing and dislodged vinyl siding on a three-story home. The record is small — 12 reviews across Google and Angi from 2022 through 2026 — but consistent: a 4.7★ average from 27 Angi ratings and a 5★ average from 4 on Google, with reviewers repeatedly pointing to fast response (same-day quotes, crews starting within days) and follow-through. A couple of Angi reviews from 2023 mention smaller loose ends — one customer says some railing parts hadn't been repainted when the crew first said the job was done — but in each case M&M came back and finished the work. For deck, stair, masonry, or trim repair work, M&M's record points to a responsive, hands-on crew; given the small review count, it's worth asking for recent local references on a project of any size.
Having used M&M Carpentry and Masonry before, for prior projects, I recently hired Mynor and his crew to help finish the first floor of my home. The project included extensive prep work, painting, trim repair and replacement, a new door installation, and new tile flooring in the bathroom. Throughout the process, the team was professional, detail-oriented, and communicative. I especially appreciated their willingness to work with my requests and preferences along the way. They consistently checked in to make sure everything was progressing the way I wanted, which made the experience smooth and collaborative. The finished work looks great, and I’m very pleased with how everything came together.
Mynor and his crew could not have been better to work with. He was very confident in his ability to do the masonry and carpentry work required on my large two car detached garage and he completely delivered. I am so happy with how it turned out and he was great with communication throughout the entire project. On top of that, he came up with an awesome solution to the framing for the front doors. I will most definitely be using M&M Carpentry and Masonry again in the future!
M&M is a great company that simply does exceptional quality work. No need to look further for all our future needs! They are professional, and their attention to detail is fantastic. Maynor and his team did an amazing job renovating my kitchen, among other jobs I had around the house. Reliable, very responsive throughout the entire process, courteous in all interactions, and a big project completed ahead of time! I would highly recommend Maynor to anyone looking for a trustworthy, skilled, professional contractor.
I’m Just going to that I WISH I KNEW THESE GUYS BEFORE. I bought my house about a year ago and it had a ton of stuff to be done. These guys came over and helped me with everything my whole kitchen, part of my roof, a deck, siding, floors, and a masonry project down in the basement. Mynor gave me fair price but what got me impressed was his sincerity and quality of the job that needed to be done. These guys are AMAZING AND HIGHLY RECOMMENDED. I hope that if ever get something to be done they can fit me on their schedules. Thank you so much guys words can’t express how grateful I feel about you guys.
Awsome work. Awsome price. Just an awsome person to hire. M&M Carpentry & Mason. I will be calling Mynors again for another project. Thank you again Mynor, beautiful work well done.
