Senior Living Construction in Derry, NH 

Home Modifications & Accessibility Upgrades for Derry Residents

When a home needs to work better for an older adult, the project rarely touches just one trade. A stairlift installation may require an electrical circuit. A kitchen modification for an elderly resident might involve plumbing, carpentry, and new lighting in the same afternoon. Cornerstone Services handles all of it under one roof through our dedicated Home Modifications division, serving Derry, NH, and surrounding communities in southern New Hampshire. One call covers the full scope of your senior living construction project, without the back-and-forth of coordinating separate contractors.

Our Home Modifications division provides wheelchair ramp installation, grab bar installation, stairlift installation, kitchen modifications for elderly residents, and smart home setup for elderly and disabled clients. Backed by more than 1,250 five-star reviews across Google, HomeAdvisor, Facebook, and Yelp, our team brings the same accountability to every accessibility project that has built our reputation across every trade we touch. That’s the idea behind our tagline: One Call Does It All.

Ready to make your Derry home safer and more accessible? Call us today at (603) 874-1402 or visit our contact page to schedule your consultation. Same-day service is available for urgent needs.

Senior Home Modification Services We Provide

Aging-in-place modifications are most effective when they’re scoped to the resident’s actual needs and the existing layout of the home. Our background-checked technicians assess each project before work begins, so every modification is planned around your specific situation rather than a one-size-fits-all approach.

Named services under our Home Modifications division include:

  • Wheelchair Ramp Installation: Custom ramp construction for exterior and interior access points, designed around your home’s entry configuration and the resident’s mobility requirements.
  • Grab Bar Installation: Strategically placed grab bars in bathrooms, hallways, and stairwells to reduce fall risk where it’s highest.
  • Stairlift Installation: Motorized stairlift systems fitted to your existing staircase, keeping multi-level living accessible without a full remodel.
  • Kitchen Modifications for Elderly Residents: Counter-height adjustments, pull-out shelving, lever-style hardware, and improved task lighting to support safer, more independent daily living.
  • Smart Home Setup for Elderly and Disabled Clients: Voice-activated controls, automated lighting, and remote monitoring solutions that reduce reliance on physical dexterity for everyday tasks.

Beyond the five named services, home accessibility construction often calls for related work in electrical, plumbing, or HVAC. Because Cornerstone Services covers all of those trades through a single provider, any secondary work your project requires doesn’t mean a second contractor. Our uniformed professionals arrive in lettered vehicles and clean up completely when the job is done, leaving your property in clean condition.
