"I recently had my shingle roof replaced and I?m very happy with the results. The team was professional, punctual, and completed the job efficiently. The quality of the work is excellent, and the new roof looks great. They kept the work area clean and communicated well throughout the process. I would definitely recommend them to anyone needing a roof replacement."

"Glenn was great to work with. He first painted 2 rooms. One had very high ceilings and was a very dark color. He was very fast with both rooms. Then he sanded and refinished wood floors on 2 levels. I wish I had before pictures. The floors had been nearly destroyed by the previous owners dogs. I didn't have too much hope for them, but they look nearly new. Glenn kept us updated with his progress, left the house very clean, and the floors look great. We plan on hiring him again for future projects."

"I had serious water problems in my basement, and a crumbling foundation. The concrete block foundation had lost a lot of its grout and was bulging dangerously. Wright straightened the wall, installed French drains on two sides of the house, insulated the interior walls and ceiling of the basement, and installed a thick plastic vapor barrier on the floor. They poured about four inches of cement on the floor and installed a heater that will keep the temperature above freezing in the basement. This makes it easier to turn on the water and to heat the upstairs if I come up in the winter. The cost was about $40,000. I was very pleased with Wright's workmanship, responsiveness and the quality of their staff. I would recommend Wright without hesitation to anyone with an engineering problem."

FAQs for garage building service projects in Hanover, NH

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.
