Eli Matta builds the big pieces. A July 2026 customer said the garage and mudroom addition Eli built was a fairly large and complex project, that the quality was good, that he is easy to get hold of and that he stands by his work. In May 2026 a Hanover homeowner had kitchen and bathrooms come out better than expected, had the foundation waterproofed in the same job, and said the basement now has zero humidity — at a price that beat four other estimates. Altitude Builders is based on King Avenue in Weymouth. Its Better Business Bureau profile names Elias Hanna Matta Sr. as owner, records three employees, and carries an A+ grade with accreditation since October 2018. Massachusetts confirms home improvement contractor registration 190233 as active in the company's own name. Its HomeAdvisor page separately lists a Massachusetts trade licence numbered CS-111663 expiring in February 2027, and Houzz lists 111663 — directory-supplied numbers, so ask to see the licence covering your particular job. The company tells its own history three different ways. The website says "since 2009" in one place and claims over 30 years of hands-on experience in another; the BBB profile records the business as started in 2006 and incorporated in 2017; the HomeAdvisor page says family owned and operated since 1992. Worth settling which date belongs to the company you would be contracting with. The written history runs thin across eight years, and it is not uniform. In a May 2019 HomeAdvisor review a customer called the job an absolute nightmare, said it took over three months — three times longer than predicted — and described the experience as hell. HomeAdvisor's four ratings split 75% five-star and 25% one-star. From the same era, a May 2020 customer who replaced an old rotting deck said Eli was professional and straightforward about the choice between composite and pressure-treated wood and reasonable on price, and an October 2025 custom-home client praised the process from the design phase through the final walk-through. One more thing to settle in writing: the HomeAdvisor profile states that no warranties are offered, while the company's own site offers a one-year workmanship warranty. Ask which applies to your contract. Altitude is a reasonable call for an addition, a kitchen or bath, or a full renovation on the South Shore. Given the 2019 account, put the schedule, the milestone dates and what happens if the job overruns into the contract before you sign.
Eli built my garage and mudroom addition, which was a fairly large and complex project. He and his team did good quality work, and he is easy to get in touch with. It is hard to find trustworthy contractors these days - I highly recommend Altitude Builders. Eli stands by his work.
I used altitude builders for my home renovation in Hanover. they were very good. The kitchen and bathrooms came out better than I expected. They also waterproofed my foundation. Now my basement has zero humidity. I would recommend these guys. Their price was better than 4 other estimates I got!!
I recently worked with Altitude Builders Inc on a custom home project, and I couldn't be happier with the results! From the initial design phase to the final walk-through, their team was professional, communicative, and truly listened to our needs. The quality of their work is top-notch, and they stayed on schedule and budget. The attention to detail and commitment to excellence is impressive.,If you're looking for a reliable and skilled builder, I'd highly recommend Altitude Builders Inc. They exceeded our expectations and delivered a beautiful home that we'll enjoy for years to come. 5/5 stars!
Yes, I recommend this pro. We hired Altitude Builders to replace an existing deck that was old and rotting. After vetting out several contractors to decide between composite or pressure treated wood, we found Eli to be professional, straightforward and reasonable when it came to our ideas on what we wanted in a deck. His timeline and pricing was the best. He presented us with all requested documentation (contractor license, insurance, and contract) and started on the day he stated. Project went slightly longer because we needed additional footings and extension beyond the original scope of work. At the end of each day, the site was clean and nothing was left out of place. My deck is solid, sturdy and beautiful! His workmanship and professionalism were wonderful. We will be using Altitude builders again for additional work in the near future. Highly Recommended!
I struggle to find the words to convey what an absolute nightmare it was working with this man. He made our lives hell for over three months, which was, incidentally, three times longer than he had predicted it would take. At first, it seemed like a good fit. He shared the same heritage as my partner, so we thought this would contribute to general good will, and it did at first until he and his team started making mistakes. It was a regular bathroom renovation, nothing too complex, but somehow every error turned into a fight. First it was the shower floor, which was tiled incorrectly. He never bothered to discuss with us how we wanted it done, and did it differently. At first, he indicated he would correct it, then he reneged. We were inclined to push the issue, but we decided to accept it because we did not want the job dragging on for another month (which of course it did anyway). Next, the wall outlets were set up at the wrong height, right in the path of the tiling. He refused to fix it. Thankfully, his tiling subcontractor was not such a monster, and he agreed to fix it for us behind the boss's back. The boss got wind of it, and had the nerve to get upset with us, for asking one of his workers to fix his mistake. Then the floor tiles were uneven. Refused to fix. Then the soap dish was not centered. Refused to fix. My partner volunteered to fix that himself, just to try to avoid conflict, not that it worked. The only thing he was actually willing to fix was the shower chair. Not that he did not try to get out of that one too. He actually had the audacity to say the chair was --just cosmetic-- and --not meant to actually sit on--. Of course, I called the company that made the chair, and they assured me he was lying, and that the chair was meant to be used. The final insult had to do with a custom cabinet he agreed to make for us. He priced it for us in writing, but it was not part of the original contract, though it was discussed from the beginning. He told us the cabinet would be ready about two weeks after the rest of the bathroom work was done. Two weeks passed, and he demanded payment for the full job, with no indication on the progress of the cabinet. We said we wanted the cabinet and would pay for everything together. He promptly reneged on his promise to make the cabinet at all and threatened to sue if we did not pay for the balance of the job. So we paid, because who needs that kind of headache? Now my lawyer tells me that was a mistake: we should not have paid. It is an expensive lesson, but I learned that it is easier to resolve disputes before making payment. We may still sue of course. My lawyer is a close family friend and offered to take the case for free. My only hesitation is my deep, powerful urge never to see or have anything to do with this man again. And it is not just the errors with the job and his lack of pride in his own work. It is mostly his rude, aggressive, and uncompromising manner, and the abysmal way he treats his own employees. So please take my advice and scratch this one off your list. You will not realize just how much of a headache I have saved you. [Response from Altitude Builders, Inc.: "Those 2 guys they themselves partner Was a nightmare doing their project Changing ideas all day long Had my guys rip out all the tiles they choose Cause doesn't liked They refuse to pay changing order And even didn't pay us so that's the reason For the bad review They blackmail me for give up the last payment Instead the review"]
