Massachusetts General Contractor is a Lynn company that takes on everything from a clogged sink to a full kitchen and bath remodel, and its customers keep naming Guillermo. In a January 2026 Google review, a customer said they called about a clogged sink and the crew came out the same day. A February 2026 customer said Guillermo and his team executed the vision they had for their kitchen and bathroom, and a January 2026 customer said their bathroom remodel and flooring came out well. In a March 2025 review, a customer said Guillermo showed up on a Sunday to fix a plumbing issue. The company's website lists home improvements, remodeling, renovations and repairs, and a September 2024 customer said it handles plumbing, electrical, woodwork and masonry. Low prices come up often: several reviewers call the crew affordable or reasonable. Google shows 4.8★ from 56 ratings, with reviews from 2019 to 2026, and its BBB page is an A+. Two customers describe real problems. In a September 2024 review headed "Low on Price. Low on Quality," a customer said they chose the company for its lower price, and a few months after the remodel tiles were coming off the walls, the vanity shook on loose hardware, the floors were going uneven and outlets tripped when appliances switched on. In April 2022, a customer said Guillermo gave an estimate right away but didn't get back in touch once the contract and start time were agreed; a second worker then tried to charge more than the estimate and, once paid, didn't finish the job, and the customer called Guillermo a scam artist.

Guillermo was helpful, what i liked about it he was detailed, respectful, patient, and provided information on what he found and how to avoid it from happening again. For frozen pipe repair & for providing with the home heating inspections & recommendations Would recommend him for sure
Guillermo and his team did excellent work. He perfectly executed the vision we had for our kitchen and bathroom. He got everything done on time and to completion. Very responsive and knowledgeable, and patiently answered all my questions. We’ll definitely work with Guillermo again—great guy!
I called Massachusetts General Contrator for a clogged sink, and they were able to come out the same day. Guillermo and Johnny were prompt, professional, and had the issue fixed in 30 minutes. He even cleaned up the area afterward. Highly recommend for fast and efficient service!
