Our services cover a wide range of handyman tasks for residents and businesses in Derry, NH. Every trade on this list is backed by the same warranty and pricing structure, with no switching contractors and no gaps in coverage.
- Repairs & Maintenance: Doors that won’t latch, cracked drywall, worn windows, and everyday wear and tear on residential and commercial properties are handled by our crew before they turn into larger problems.
- Plumbing: From replacing leaky faucets to upgrading fixtures, our licensed plumbers are on the same team handling your handyman work, so there’s no separate call to make when a repair crosses into plumbing territory.
- Electrical Work: Light fixture replacement, troubleshooting, and electrical repairs are handled by licensed electricians. New Hampshire requires a licensed electrician for electrical work, and ours are already on staff.
- Custom Carpentry: Shelving, furniture assembly, and custom space solutions built to fit your home or office.
- Exterior Projects: Gutter cleaning, fence repairs, deck maintenance, and more. The outside of your property gets the same attention as the inside.
Home Modifications & Accessibility Services
We offer a dedicated home modifications service line for clients planning aging-in-place upgrades or accessibility improvements. Wheelchair ramp installation, grab bar installation, stairlift installation, kitchen modifications for elderly residents, and smart home setup for elderly and disabled clients are all available through Cornerstone Services, the same provider handling your other handyman, electrical, and plumbing work.
Families managing these projects after a health event or change in mobility often find themselves coordinating multiple contractors. With our single-provider model, the same team, the same warranty, and the same flat-rate pricing structure cover every part of the job. Ask about our home modifications service when you call.
