Cornerstone Services

One Call Covers Every Trade in Your Home

Most home service calls end with a phone number for the next contractor. Ours don’t. Cornerstone Services handles electrical, plumbing, heating, air conditioning, cleaning, handyman work, and home modifications under one roof, so you’re coordinating with one company instead of juggling three. Every trade runs through the same pricing structure and the same signed workmanship warranty, so the way we show up for an outlet repair is the way we show up for a boiler install or a deep clean. That’s the model we built, and it’s why customers across southern New Hampshire and northern Massachusetts keep calling us back.

We’re available 24 hours a day, 7 days a week, with same-day scheduling available for jobs that can’t wait. Call Cornerstone Services at (833) 633-5440 to schedule service or get answers from our around-the-clock staff.

1,250+ Five-Star Reviews & Counting

We let our work speak for itself. From quick repairs to major installs, our customers say it best.

Why Salem Homeowners Trust Us

When you call Cornerstone Services, you’re not getting an estimate that grows once the work starts. We price by the job, not by the hour. The number we quote is the number you pay at completion, with no adjustments, no hourly overruns, and no hidden fees tacked on at the end. Every job we finish is backed by a signed warranty under our quality assurance policy, and that coverage applies across every trade we handle, not just selected services.

Every technician and cleaning worker we send to your home or business has passed a background check before setting foot on your property. It’s a standard we hold across every service line, so you don’t have to think twice about who’s coming through your door.

A Division Built for Accessibility

One service line that sets us apart is our dedicated home modifications division. We serve elderly and disabled residents with accessibility upgrades that aren’t commonly offered alongside licensed electrical, plumbing, and HVAC work. Wheelchair ramp installation, grab bar installation, stairlift installation, kitchen modifications for seniors, and smart home setup for elderly and disabled clients are all available through the same company managing your other home services. When a project crosses trade lines, you’re still making one call.

Financing options are available across our service lines, and we run rotating monthly promotions that can apply to scheduled work. We serve homes and businesses throughout Rockingham, Hillsborough, and Essex Counties. 

Ask about current offers when you call (833) 633-5440.
