Wheelchair Ramp Installation in Londonderry, NH

Home Modifications for Accessibility, Done Right the First Time

Cornerstone Services has been installing wheelchair ramps in Londonderry and across southern New Hampshire for more than 20 years. We’re licensed, insured, and part of a dedicated Home Modifications division that pairs ramp installation with grab bar installation, stairlift installation, kitchen modifications for elderly residents, and smart home setup for elderly and disabled clients. With more than 1,250 five-star reviews across Google, HomeAdvisor, Facebook, and Yelp, our track record speaks clearly.

Whether you need a temporary ramp during a recovery period or a permanent solution built into your entry, we design every installation around your home’s specific layout, entry height, and day-to-day use.

Ready to improve accessibility at your Londonderry home? Call us now at (603) 874-1402 and our on-call team can get you scheduled, often the same day.

What Our Wheelchair Ramp Installation Covers

Accessibility needs are often time-sensitive. A discharge from rehabilitation, a change in a family member’s mobility, or a recent health event can make a ramp a necessity within days, not weeks. Our installation process is built around that reality.

Every project starts with a site assessment of your home’s entryways and surrounding environment. We evaluate entry height, available footprint, slope requirements under ADA guidelines, and whether the user will navigate independently or with assistance. From there, we custom-design your ramp to fit your home’s layout and architectural character.

  • Custom design: Every ramp we install is shaped to the specific contours and style of your home, not adapted from a generic template.
  • Built for New England weather: Ramps are constructed to handle New Hampshire conditions and sustained daily use.
  • Flat-rate pricing: We price by the job, not by the hour. The number we quote is what you pay at completion, with no adjustments, hourly overruns, or hidden fees.
  • Same-day scheduling: When you need a ramp quickly, call us. We’ll work to get a team out the same day.

Why Londonderry Homeowners Choose Cornerstone Services

Managing an accessibility transition for yourself or a family member often means handling several modifications at once: a ramp at the entry, grab bars in the bathroom, and a stairlift for multistory access. Coordinating separate contractors for each creates unnecessary friction. Our Home Modifications division handles all of these through one team, one warranty, and one pricing structure.

Every worker we send to your property has passed a background check before entering your home. Uniformed professionals arrive in lettered vehicles equipped with the tools needed for the job, and our technicians clean up completely when the work is done. You won’t be left with a mess.

Every completed job is backed by a signed workmanship warranty under our quality assurance policy, giving you documented protection on the work rather than a verbal promise. Financing options are available for homeowners who want to spread the cost of modifications over time. Ask about current terms when you schedule. We also run monthly promotions that can reduce costs on scheduled services.

Cornerstone Services is licensed and insured for Londonderry homeowners. Visit our contact page to schedule your wheelchair ramp installation and get your home modifications handled with one call.
