A concrete slab had been leaking into the apartment below for decades before Skylight Roofing and Masonry looked at it. The customer, writing in July 2026, says the crew studied the problem, asked the right questions, offered a twenty-year guarantee and did a neat, effective job of it. Water is what several of these customers were dealing with — a leaking slab, a seeping foundation, a flooded basement — even though the name leads with roofing and masonry. Angi and HomeAdvisor both list the company in Somerville with 21 years of experience and a 4.5 across 17 ratings, and both mark it Approved. Its own site covers roofing, masonry, paving, chimney and fireplace work around Boston, while those directory profiles present it as a foundation specialist doing structural repair and waterproofing. The detailed praise is about diagnosis. In September 2024 a customer wrote that Skylight designed a solution to a waterproofing problem that had confounded other contractors, installed a drain that works, and found, re-pointed and sealed a foundation issue along the way. A November 2023 customer with a leak between an original foundation and a newer extension says Darragh knew exactly how to fix it and gave them a detailed description of the repair. Another from that month describes a punctual, polite crew and a site left clean by the end of the day, with Darragh the supervisor answering questions throughout. In May 2025 the estimator, John, came out the same day and work started within eight days of the quote being signed. Two accounts run hard the other way, and both involve spring 2024. A customer writing in July 2024 says they paid $9,300 that spring, had the crew back once, and still had the same problem in the same places — maybe worse — and that calls and texts then went unreturned. A second, writing in October 2025, says they hired Skylight after basement flooding in the spring of 2024 and is extremely unhappy with the work and the service. That is the thing to nail down before any money moves: what happens when the water comes back. One 2026 customer was offered a twenty-year guarantee and a September 2024 customer wrote that the company stands by its work, while the July 2024 complaint is about a callback that stopped getting answered. For a wet basement, a seeping foundation or masonry that needs re-pointing, Skylight has specific wins to point to — including a slab that had leaked for decades. Get the guarantee, its term and the callback process written into the quote, and get a name and number for who to reach if the first repair does not hold.
We have a huge concrete slab that’s been leaking into the apartment below for decades. Skylight came in, looked carefully at the problem, and asked all the right questions. They even offered a twenty year guarantee on their work. They came and did a beautiful, neat, effective job. The kicker? They were the lowest bid!
one of the most reliable, HONEST, helpful and thoughtful repair persons it has been my privilege to have met. if he can do the work you need to get done, you won’t be disappointed! he’s the real deal!
I am extremely unhappy with the work and service I have gotten from Skylight Roofing and Masonry. In the spring of 2024 I had flooding in my basement. I immediately went to Angi and messaged a few highly recommended companies. Skylight answered first. I decided to hire Skylight given their 5 star Angi ratings, excellent reviews, and given what I believed was the credibility of the staff they sent to describe the problem and how they would remediate it. I was astounded by the price but felt the foundation of my home was a critical investment. I was forced to write $9,000 checks every other day until the work was complete. They would not bill me. The total cost was $37,800. I have never spent so much for any repair on my house and I have lived here for 38 years. Skylight was not sure when they would finish but finished the work on a Friday afternoon. That made me concerned that they may not have dotted all their i s and crossed all their t s - $37,800 for a week s worth of work and they just happened to complete the work on a Friday afternoon when the day before they were not sure when they d be done. I asked to review the work and give final payment on Monday but was refused. I was forced to allow the manager to come by Friday evening to review the work he did and give him the final check, which I did. Skylight "completed" the service but my insurance wouldn't cover it. They were surprised and agreed to write a letter to the insurance company given that other customers had gotten coverage. I had told Skylight that my insurance refused coverage because the repairs were due to wear and tear and sent them the documentation. Skylight wrote the letter but did not mention that other customers had gotten coverage and did not make the case for all the work they did beyond wear and tear. They sent the letter to the insurance company without showing it to me first and gave no other details about their work except addressing wear and tear. So, of course, they gave the insurance company no reason to reconsider their position. In the process of doing that, one of the contractors came out to look at the work and noticed a problem he was anxious to fix, stating he wanted to be sure everything was done correctly given their 25-year warranty. This was in August of 2024. Nothing was scheduled. My basement then flooded in the fall at the first heavy rain at the site of their very expensive work. They agreed to fix everything but they've been putting me off since last August. It is now September 2025. I placed many phone calls and texts and always was met with promises to assign someone to repair the work. This has caused me a great deal of anxiety. I now have no faith in the work they have done. I would not ever recommend them to anyone and wish I had never hired them in the first place. I don t understand how they have such positive reviews - they were all positive when I hired them. Although I recently saw one significant negative review similar to mine on Home Advisor regarding poor follow-up and lack of response for warranty work after an upfront payment. Given all the money I ve invested and the 25-year (!) warranty they gave me, I would like my money returned so that I can hire a reputable firm who will do quality work and truly guarantee their work.
I can’t say enough 5 Star work. The estimator John came out the same day. I know that’s unheard of! Then they started work within 8 days of signing the quote. Quality of work, great speed & phenomenal communication couldn’t be happier! Chris from Reading
John is an awesome guy! ... John is methodical, taking his time to listen to every concern you have. He is very re-assuring and does not over sell! ... John is welcome to visit anytime! ... I considered him a friend the moment I met him, which was the initial inspection!
