"Absolutely, I’d be happy to help you out with that review! Here’s a glowing one for Tri Build Construction and Ray: --- I recently had the pleasure of working with Tri Build Construction, led by Ray, and I can't say enough great things about the experience. From start to finish, the work was absolutely fantastic. Ray and his team were the epitome of professionalism: they arrived on time, communicated clearly, and maintained a clean and organized workspace every single day. Not only was the craftsmanship top-notch, but the attention to detail really stood out. They took the time to ensure everything was done exactly as we envisioned and even went above and beyond to accommodate a few last-minute tweaks we requested. The final result was everything we hoped for and more. In short, if you're looking for a reliable, skilled, and incredibly professional construction team, I highly recommend Tri Build Construction and Ray. They truly deliver a five-star experience! "

"Hired Greg for a full gut and remodel of a bathroom. Greg was very competent, personable, and took the time to understand exactly what we wanted. He made us feel like we were in good hands. He took the time to make sure things were done the right way. The result was top notch, couldn't have asked for more. I would definitely use this company again!"

"Hector and Moises were excellent! Hector came with one other of their crew and assembled my permanent gazebo. I have stone pavers and they were very careful in cutting them and digging Deep enough to establish a good anchor. They even installed railings for my back stoop. I would highly recommend them! Clean... affordable and professional."

"We have a two story home in Patchogue that had a leak that resulted in water in the walls of our attached garage. We could not locate the cause of the leak. We contacted Exterior Team Home Services who quickly located the source of the leak which required us to replace the front roofing of our house. It was done very quickly at a fair price. We were also impressed on how they made sure the old roofing material did not get into our front lawn or plants. They were meticulous in the way they treated our property. A job well done."

Customers say: Quick response

"<p>This is the 2nd major project I contracted Art DeRosa & Co for.  The 1st being 4 years ago a major living room/family room renovation which was hugely successful.  That 1st experience led me to award Art (after several other competitive quotes) this 2nd and far larger & more complex project.<br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /></p> <p>Overall it went well but this was a complicated project encompassing all the typical trades and expertise of building a new luxury house but far more complicated because it was a renovation performed while we were living in the home. Dust partition walls with wood framing had to be erected in several locations in the house which included temporary doors for entering and egress in certain areas of the remaining living areas of the house in order to protect the remaining house from dust and demolition , as well as, provide privacy for us during construction. </p> <p>Experience, Experience, Experience and Professionalism, Professionalism, Professionalism are the hallmarks of Art DeRosa and company.  He is a seasoned performer and pretty much seen it all.  Art has such a vast amount of home construction experience in both hi-end and medium end homes that he can draw upon a wealth of knowledge in all construction disciplines to implement a fine finished result.  As a former tool and die maker his penchant for hi-precision finish work yields highest quality appearances to things like moldings; trim; windows; doors; floors; etc. etc. </p> <p>This complex renovation project lasted 7 months which was within the initial time estimate given at the beginning and Art DeRosa and team were here every single day, day in and day out,  bright and early during that time frame. He did not start any other projects and stayed on the job day-in and day-out even when other sub-contractors such as plumbers and electricians were on the job site excluding his people from doing any other work. Art DeRosa and team were here every single day until final signoff.</p> <p>I would not hesitate to recommend Art DeRosa & Co for any planned New House and/or House Renovation of any kind.</p> <br />"

"This was the second time we hired AJC Designs and, as with the first time, Arty and his team did a great job! The previous job (extension, interior renovation, decking) was larger than this one (reconfigured fireplace wall, extended closets, installed a laundry room and constructed a beautiful stand-alone 3 season pavilion) but both jobs exceeded our expectations. From assistance with finding an architect through the 6 weeks of building, Arty responded to any question/request quickly. His team of carpenters, painters, and the electrician were consistently courteous and professional, routinely checking-in to ensure the project was coming together as we wanted. So pleased with the results!"

FAQs for garage building service projects in Stony Brook, NY

A well‑constructed, properly permitted detached garage adds between $12,000 and $36,000 to a home’s resale value. Buyers appreciate the secure parking, extra storage, and flexible workspace, so appraisers often bump the property’s value accordingly. The exact return depends on the garage’s size, finishes, and how well it matches the main house, but most homeowners see a strong ROI when the build meets local codes and passes inspection.

Yes—once it meets local building codes and you secure the proper permits, a detached garage can be converted into living space. Finishing the interior, adding climate control, and ensuring safe egress effectively increase your usable square footage, though it may not always count toward the official listing. Skipping permits can trigger fines and even force you to undo the work, so always clear plans with your city first.

Most homeowners policies cover a detached garage under the “other structures” provision, but coverage limits vary. Review your declarations page and ask your agent how much protection you have for separate structures. If the limit is lower than the garage’s replacement cost, you can raise it for a modest premium. Confirming the details now prevents headaches if you ever need to file a claim.
