"I had a great experience with the Exterior team company. Ronald was very punctual in the initial visit for an estimate. I explained to him that I could not be there and he scheduled another time the same day to return to discuss the estimate. He was on time that evening as well. He was very fairly priced. We scheduled the job a month out. He had all materials delivered the morning of and the crew was on site by 7 30. They worked hard throughout the day and as a thunderstorm was coming, they worked tirelessly to cover the remainder of the roof. They returned the next day, completed the job and cleaned up. The roof is looking great. I would highly recommend Ronald and his crew."

"We hired Coco’s Custom Building on 2 separate occasions. We needed our roof redone and later decided to hire them to replace a dozen windows in our home. The owner Keith provided us with a great quote each time and was able to schedule the work right away. Any questions or concerns I had were addressed immediately which made the renovation go smoothly. I would definitely recommend Coco’s Custom Building and look forward to using them with my future home renovations."

"<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 />"

"High-quality work by an even higher-quality group of professionals. From our initial meeting to through final inspection, the work performed was thorough, timely, and clean. Our budget was considered as we uncovered an inevitable project obstacle and we were able to avoid any delays with a cost-effective and efficient solution. The crew was friendly, skilled, and communicative and we could not be happier with the final result!"

"Very admirable, i checked the list and his name came up. He came out and looked at the garage door, he said it wasn't anything in his line of work. Anyway, I stated he had come up under garage doors. He said he didn't know how, but it was okay. He then asked about my previous siding job from a different company, and i said they had left some piles of wood, and that the planks were too large for the garbage people to take them away. He stated he could cut them in half for me since he had a saw in the back of his truck, and he did not want my money for the service. I offered him 10$ for the service but he refused. I would recommend this company, and feel the deserve to be at the top of the list. He went out of his way to give me some help and didn't require payment. So very nice of him!"

FAQs for garage building service projects in Riverhead, 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.
