MJT Home Improvement is a Marlborough roofing, siding, and gutter contractor with a genuinely split reputation: about half of its written reviews describe fast, well-organized jobs, and the rest describe unfinished work, missed permits, or slow refunds. Marcos Terrenas runs the company, which Better Business Bureau lists as family-owned, A+ rated, and accredited since 2017, with 15 years in business. Its Massachusetts home improvement contractor registration, #192017, is registry-verified active. On the positive side: a 2024 review describes a fair price adjustment when old roof plywood needed replacing, with the crew starting at 7:30 a.m.; a 2021 review says a roof was replaced in a single day with a full cleanup; and several 2019-2020 reviews describe reasonable quotes, prompt scheduling, and using the company's own crews rather than subcontractors. On the other side: a September 2026 Google review says the owner stopped responding after citing family issues; a March 2026 review describes a leak into a downstairs neighbor's unit and a bounced reimbursement check tied to a ceiling fan dispute; another from the same month describes a deposit taken for a project that was never started, with months of being told materials had been ordered when they hadn't; and a March 2026 Angi review describes a kitchen and bathroom remodel where poor quality control required outside contractors to redo parts of the work - Marcos reimbursed that cost, but the dispute continued over a $940 charge to replace a fan. Older accounts describe similar patterns: a 2022 review reports shingles coming loose, warped flashing, and leaking gutters on a roof installed in 2020; a 2020 review says a promised deck-rebuild start date fell through when a permit hadn't been pulled; and a 2019 review says the company advertised one grade of roofing material to win the bid, then installed a cheaper one. Google (3★ from 6 ratings) and BuildZoom (3★ from 4 ratings) run notably lower than the 4.8★ average Angi and HomeAdvisor each show from 38 ratings. An OSHA inspection resulted in 4 citations and $19,218 in proposed penalties. Court records also show a lawsuit, Global Capital LLC v. MJT Home Improvement and Marcos Terrenas, filed against the business and its owner. BuildZoom also lists a second Massachusetts home improvement contractor license, #178909, for the company - only #192017 is registry-verified, so check the state registry directly for the second number's status. Given how often deposits, permits, and follow-through come up in the complaints, get a written contract covering the payment schedule and who pulls permits before any money changes hands, and ask for references from jobs completed in the last year or two.
“19-01858-RAM 1 Global Capital LLC v. MJT Home Improvement Inc. and Marcos J. Terrenas”
“was the subject of a formal OSHA inspection that resulted in 4 citation(s) and cumulative proposed penalties of $19,218.00.”
If i can leave no stars I would. He does not reply and he is a complete scammer, He will give you the run around and say he would have family issues. Do not trust this guy, we will be going after his license if anyone wants to file please reach out.
Great design but the lack of quality control is a serious problem. Numerous reworks needed, lies told, caused a massive leak to my downstairs neighbor and lied to me about replacing a ceiling fan and then bounced the check to reimburse me. It won't let me post half a star.
Don't trust this guy! He took a deposit from me almost a year ago for a project that he never started. A few months ago I asked for my deposit back after I found out he lied to me about ordering material for my project and continues to lie to me while slowly paying me back. He shouldn't have a contractor's license!
It was actually a kitchen and bathroom remodel. Design was good but the quality control was very poor requiring multiple rework. Ended up having to call in properly qualified contractors for which Marcos did reimburse me for. The final straw was $940 I paid to replace a fan that he said was replaced in 2023, which it wasn't. He sent me the reimbursement which bounced and now radio silence.
Marcos was very fair in his quote to have the roof done. Even when they removed the old shingles and found that they needed to replace the plywood Marcos was fair in the increase cost. His people showed up at 7:30 AM and worked like busy bees though out the day taking only half hour for lunch. They worked like an oiled machine, each new what to do and they never stopped. I highly recommend this company for any work you need done! MJT Home Improvement goes the extra mile to make sure that the job is done right and they clean up after themselves as well.
