Home Modifications for Accessibility & Hands-Free Convenience
Cornerstone Services offers automatic door installation in Derry through our dedicated home modifications division. Whether you’re retrofitting a home for a family member with limited mobility or adding hands-free entry to a high-traffic doorway, we handle the assessment, installation, and cleanup under one roof. The same division that installs automatic doors also handles wheelchair ramps, grab bars, stairlift installation, kitchen modifications for elderly residents, and smart home setup, so a Derry homeowner planning an accessibility project doesn’t have to manage multiple contractors.
We’ve earned more than 1,250 five-star reviews across Google, HomeAdvisor, Facebook, and Yelp. One call does it all.

Automatic Door Types & What Our Installation Involves
Every automatic door installation starts with a property assessment. We evaluate door width, threshold height, and clearance to determine which system fits the space and the people using it. From there, we match the right door type to your property’s layout and your intended use.
Door options we install include:
- Automatic sliding doors for wider openings where swing clearance is limited
- Automatic swinging doors with low-energy power-operated operators governed by ANSI A156.19, suited to residential and light-commercial applications
- Full-power automatic doors for higher-traffic commercial entrances, governed by ANSI A156.10
- Revolving doors where the building layout supports them
Automatic door systems typically include safety features such as motion sensor activation, safety edges, and emergency stop functions. These components help keep the door operating smoothly for every user, including wheelchair users and people using other mobility aids. Every technician we send to your property is background-checked before arrival, and our service vehicles are staged on-call from multiple locations so we arrive when we say we will. When the job is done, we clean up and leave the property as we found it.
Why Derry Property Owners Choose Cornerstone Services
Automatic door installation is a significant investment, and the way a company prices, warranties, and stands behind its work matters as much as the installation itself. Here’s how we approach it.
- Per-Job Pricing: We price by the job, not the hour. The number we quote before we start is the number you pay at completion. No adjustments, no hourly overruns, no hidden fees.
- Signed Workmanship Warranty: Every installation is backed by a signed warranty under our quality assurance policy. You get documented protection on our work, not a verbal promise.
- Same-Day Availability: Same-day scheduling is available for customers who need a quick response. Our on-call staff is reachable 24/7 for scheduling, questions, or urgent needs.
- Financing Options: Financing is available for customers who need it. Ask about current terms when you schedule.
Single-Provider Coordination
Because Cornerstone Services handles electrical, plumbing, HVAC, cleaning, and handyman work alongside home modifications, a Derry property owner doesn’t need to coordinate a separate electrician, a separate contractor, and a separate accessibility installer. Every trade involved in an automatic door project is available through the same company, under the same warranty and pricing structure. We also run monthly promotions, so it’s worth asking about current offers when you call.
Automatic Doors & Accessibility Planning in New Hampshire
Automatic doors serve mobility-limited residents, wheelchair users, older adults who find manual door force difficult to manage, and anyone moving through a doorway with their hands full. They’re an accessibility retrofit in some cases and a convenience upgrade in others.
On the code side, automatic doors aren’t mandated by the ADA for most building types, but the 2021 International Building Code introduced automatic door requirements for certain assembly, business, mercantile, and hotel occupancies above defined occupant load thresholds. For existing buildings, installing an automatic door operator at an existing swinging door can address a non-compliant condition without requiring full door replacement. New Hampshire property owners should verify whether their specific occupancy type or local building code imposes requirements beyond federal ADA standards before finalizing a plan.
