"Mateo built a 1 room 150 sf addition that resulted in a leaky foundation with water and mold inside. There were 6+ gaps/holes in the CMU walljoints that were 2”- 3+” deep where water easily penetrated. Also his tape and sheet rocking has cracked/gapped on all walls and the vaulted ceiling. The worst part was Mateo refused to stand behind his work and I had to get another contractor to remedy his work."

"Peak did an excellent job. They removed furniture to storage, dismantled cabinets and removed to storage, ripped out old floor and subfloor, replaced insulation under subfloor, installed new plywood subfloor and new 3/4 in. prefinished oak floor, then reinstalled cabinetry and painted as needed. The Peak employees we dealt with were all polite and professional and we were extremely pleased with their work. We highly recommended Peak Construction."

FAQs for garage building service projects in Cornwall, 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.
