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.







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. 

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. 

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.

I would not hesitate to recommend Art DeRosa & Co for any planned New House and/or House Renovation of any kind.

"THE CO. REMOVED THE OLD DRIVEWAY ASPHALT, LEVELED THE GROUND, REMOVED OLD DEBRIS, AND REPAVED WITH NEW ASPHALT. THE DRIVEWAY LOOKS GREAT. THEY LEFT THE PLACE VERY CLEAN AND WHILE DOING THE JOB DID NOT INCONVENIENCE ME IN ANY WAY.THE COST WAS APROX $3200
ON THE 2ND CONTRACT, THEY SIDED AND REPLACED THE WINDOWS IN MY OLD BARN, WHICH WAS CONVERTED TO A GARAGE MANY YEARS AGO. THE BARN WAS NEVER SIDED (WAS BUILT IN 1912) .THEY INSTALLED THE SIDING, THE NEW WINDOWS, REPAIRED THE DAMAGED WOOD, CLEANED AND PREPED THE GARAGE, INSTALLED INSULATION, CREATED A SOFFIT (THE BARN HAD NEVER HAD A SOFFIT). REFRAMED AND SHIMMED THE NEW FRAMES AND INSTALLED NEW ALUMINUM TRIM ALL AROUND.MY BARN NOW LOOKS LIKE A COMPLETELY NEW STRUCTURE.
ONCE AGAIN THEY CAME AND DID THE JOB, EFFICIENTLY, CLEANLY, AND DID NOT INCONVENIENCE ME.
I WAS ALSO VERY PLEASED WITH THE COST
MY NEXT BIG JOB WILL BE FINISHING MY BASEMENT NEXT YEAR AND I WILL MAKE SURE TO GIVE THEM A CALL WHEN I AM READY.

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.
