"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!"

"I'm so happy that I went to Gamco for a remodel of my sunroom/den. The room was originally on a brick floor which had shifted over time. The owner, Gordon, suggested a "floating" floor over the bricks as well as lifting the doors to accommodate the higher floor. Ron, who completed the job was absolutely amazing. He was professional, meticulous and was very reassuring on how everything would look. The room is so much nicer than I imagined it would be. I can't say enough good things about Gordon and Ron. I highly recommend them and will be contacting Gamco Remodeling for my next renovation. Thanks again Gordon and Ron!!!"

"Gotham Builders went above and beyond when doing our kitchen renovation. The guys showed up on time and were early some days and cleaned up everyday before they left. They listened to our concerns and desires and they made excellent suggestions and came thru making the kitchen of our dreams. They also started and finished exactly when they said. Of course there were hiccups but when it looked shaky they came up with great solutions. I now have them doing another renovation. Everyone was good but Alberto and Cat were outstanding they approached the job with concern for what we wanted and needed."

"Fernando and Francisco were fantastic! Professional, punctual and reasonably priced. They did a beautiful job rebuilding some stone pillars for us and replacing damaged fencing. Also power washing. Could not have been more satisfied with the work."

FAQs for garage building service projects in Holtsville, 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.
