    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!

The honest read

Massachusetts General Contractor (Guillermo and crew) is repeatedly praised for kitchen and bathroom remodeling quality, being responsive, and keeping jobs on schedule or “on time.” There are strong concerns from at least one recent review alleging poor workmanship after a remodel (tiles and vanity issues) and another complaining about poor follow-through after an estimate—so it’s worth clarifying expectations and timelines in writing.

Where sources disagree

  • Most reviews are 5★ praising quality and professionalism, but at least one 1★ review describes quality problems after a remodel (tiles/vanity) and another 1★ review alleges the contractor stopped responding after the contract/start time. This disagreement lowers confidence.

What the evidence shows

Worth knowing

  • At least one 1-star review alleges low quality after a remodel, including tiles coming off and a vanity shaking due to loose hardware.

  • Another review (1-star) claims the contractor was unresponsive after the contract/start time, eventually saying they were too busy and would use someone else.
