M&M is a Lynn crew for the jobs where carpentry runs into masonry — a deck whose stairs have to meet a new patio, a detached garage, flashing torn off a wall. Customers ask for Mynor or for Mauro by name, and several of them come back. A May 2026 customer who had used the company on earlier projects brought the crew back to finish the first floor of the house: extensive prep, painting, trim repair and replacement, a new door and new tile flooring. In September 2025, a homeowner hired them for the masonry and carpentry on a large two-car detached garage and said the result matched what was promised, with communication to match. A July 2024 reviewer who had bought a house the year before went through the list of what got done — the whole kitchen, part of the roof, a deck, siding, floors and a masonry project. Outside, the work is quick-turn. In a 2023 Angi review, poor construction on a deck was repaired and a new set of stairs built to fit a new patio, done inside two days between rain storms. Another 2023 customer got a same-day quote from Mauro, then had the back deck pressure washed, repaired and stained and the stairs and fascia boards fixed. In 2022, a homeowner who lost several feet of aluminum flashing off a three-story house to wind had that and dislodged vinyl siding put right quickly, at prices they called fair. Scheduling is where the friction shows. A 2023 four-star customer who had stairs repaired, broken columns replaced and the porch painted and stained hit a couple of delays, for rain and for another job, and the one complaint raised involved some old railing parts. For deck and porch repair, exterior trim and the masonry that goes with them, this is a small outfit that quotes fast and works fast. Ask how rain days move your dates, and settle up front what happens to the old railings and trim that come off.
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.
