"My husband and I used David in the spring for the home inspection on a property we ended up purchasing. He was easy to get ahold of, available quickly, and incredibly knowledgeable. We purchased an almost 4000 square foot, 135 year old home, and David went out of his way to check every square inch of that property. He arrived early and had already checked the exterior by the time we got there to join him. He was excellent to deal with, made the process painless, and had some great advice for my husband and I as new homeowners. The follow up email with his report was detailed and included photos of every part of the house. His pricing was also very reasonable, especially considering the size of the home. Highly recommend!"

"Be careful. I called to have a radon mitigation system installed and the sales rep on the phone took down the information and scheduled the appointment. I was upfront about an interior drain being installed. When the technician arrived, he said he'd be happy to install the system, but that it would be worthless because of the interior drainage system. I then received a $200 invoice for the site visit. Frustrating scenario to have a sales rep schedule the appointment, knowing full-well that I had an interior drain, and then the technician tell me there's no point to install a mitigation system, but then charge me for the inconvenience of it all."

Customers say: True professional

Recommended by 90% of Angi customers

Canty Brothers Construction is a veteran owned & operated company specializing in high quality design-build services: home remodeling, commercial renovation, custom home building & design. Serving the Metrowest / Greater Boston / Central Massachusetts area for over 30 years. Allow our dedicated Canty Brothers team, led by owner John Canty, including project managers, carpenters and designers, to bring their extensive knowledge and expertise in delivering complete customer satisfaction & exceptional service in making your dream home a reality.

"Overpromised, underdelivered Any renovation project has its ups and downs, but there are a few cornerstones that ensure an overall successful project for the client and contractor: Open communication, Transparency, and Follow Through. While we greatly appreciate the work of the carpenters, plumbers, and electricians who worked on our home--and there are some features of the home we very much love, I would not use this company again. Canty Brothers has a great sales team. They know exactly how to approach a client and provide the information to make a prospective client excited about the possibilities, however the follow through once the contract is signed is very different from the sales pitch. Once we signed the contract, we found communication became difficult, unless they were looking for a payment. We paid 650k for a complete renovation of a 1963 home south of Boston. The 1963 home was about 2700 square feet. We had an addition put on over the garage. The main living space is closer to 3200 square feet now. We also finished the basement. First, we were assured they would begin the project on time. The project was delayed starting by over a month. We were told initially that materials would be "middle of the way," but if we chose anything that wasn't builder's standard, we were charged extra. Many of the things we agreed upon in an email prior to the contract and in person, were not included in our final project. For example we were shown Master Cabinets and told that was what we would receive, but were downgraded to Fabuwood in the contract. It's difficult to push back when you are trying desperately to get them to complete work. We often felt we had to just accept whatever was happening because we worried they would simply stop working. In addition to the aforementioned, the construction crew caused a significant leak in our basement by damaging the water meter. We were charged for the repair. There was no leak prior to the crew working in the basement. The prior owners did not have an issue with this meter, either. Aside from incomplete or poor/sloppy workmanship, Canty Brothers did not care for our yard. There was significant debris, including glass and lead shingles from the previous house exterior left along the property. I have taken pictures of some of what I cleaned up personally. Once we moved into the house, we experienced a water leak in main bathroom through to the first floor, a gas leak due to a poorly sealed pipe, and our AC was not properly hooked up. These major items were addressed, but a better attention to detail could have prevented this. The design flaw with the gas vent, which vents out toward our patio, rather than up through the roof, means we can't have the back windows open unless we want the house to smell like natural gas. It is a design flaw that another company might possibly not have made, in my opinion. In addition, we now have water in our basement. When I called to ask that the sump pump I had originally asked be installed be included, John Canty, the owner, became incredibly belligerent. He assured me water would not get into the basement, and now that it has he wants to charge us for the sump pump that should have been originally installed when I first requested it. Almost three months after providing our final payment (despite agreement at walk-through that all work would be complete in thirty days), there are items that still haven't been completed or addressed. Our main gas fireplace insert has not been installed, despite being part of the contract. The backfill that was used to fill in damage to the yard contained broken dish fragments, large pieces of glassware, and other debris. It has been a struggle to grow grass, as a result. We will have to redo it in the fall. The house wasn't sealed completely, despite being told that we would rate "like a brand new home." I have yet to see that information, despite asking for it. I have maintained pictures of some of the workmanship. We have found vendors who can complete the work left incomplete by this builder, but we should not have to considering the premium we paid. Use this company with caution."
