Discover the Story Behind Door Services Corporation: Who We Are and What We Do

For facility managers, maintenance teams, and healthcare operations leaders across the United States and Canada, that call comes to Door Services Corporation.

We're part of Door Services Corporation, a Horton Automatics company. We repair, maintain, and install every major brand of commercial and automatic door, for every type of facility, with AAADM-certified technicians who respond the same day, fix the problem right, and explain what they did before they leave.

A lot of service companies drop in, swap a part, and move on. Our technicians take the time to walk you through what went wrong and what to watch for next time. It's old-school service. It's also just how we think the job should be done.

Our History

Horton Automatics invented the automatic sliding door in 1960. Door Services Corporation grew from that foundation, and for over 60 years we've been building on it, adding service capabilities, expanding locations, and keeping the same technicians around long enough to actually know your building.

Door Services Corporation has been serving facilities in this market as part of that network. Today, Door Services Corporation operates across more than 20 locations in the United States and Ontario, Canada.

We're a local team of certified technicians who have been doing this work, in your market, for years. When you call, you reach someone who knows the difference between a Horton S2001 and a dormakaba operator. And can fix either one.

What We Do

We service, repair, and install commercial and automatic door systems of every make and model. That includes:

• Automatic sliding, swing, folding, and revolving doors
• Manual commercial doors and hardware
• Fire-rated and life safety doors
• ADA-compliant entry systems
• Healthcare doors including ICU, cleanroom, and infection control applications
• Security and access-controlled entryways
• Drive-thru and pass-thru windows

Brands we service include Horton Automatics, Stanley Access Technologies, ASSA ABLOY, dormakaba, GEZE, Boon Edam, Nabco, Tormax, Won-Door, and all other recognized North American and European commercial door brands. If you have a commercial door, we can service it.

Why Facilities Teams Work With Us

We show up, fix it right, and stay until it's done. Our customers have been saying that in reviews for years. One client has worked with us for 19 years. That's not a coincidence.

A few things that matter to the people we work with:

Same-day response. For emergencies, we don't schedule you for next week. We come out.
AAADM-certified technicians. Every technician is certified, background-checked, and trained across multiple brands and door types. You'll see the same faces on repeat visits. We don't rotate strangers through your facility.
Every brand, every door. We fix what you have, whatever brand it is.
Preventative Maintenance Agreements. Many of our customers start with a single service call and move to a PMA once they see how it works. A maintenance agreement typically saves 25% or more compared to reactive repair, and it means fewer emergency calls for you.
Transparent pricing. The quote you get is the price you pay. No surprise line items, no after-the-fact upcharges.

Who We Serve

We work with anyone responsible for commercial doors, whether that means keeping them running day to day, replacing something that's past its service life, or installing new systems.

Our customers include:

• Multi-site facilities directors managing large door portfolios across multiple properties
• Maintenance managers who need a reliable vendor and fewer emergency calls
• Healthcare facilities leaders who need credentialed, protocol-aware technicians on site
• Property managers looking for a single vendor across all door types and brands
• General contractors and construction firms coordinating commercial door installation
• Glass and glazing contractors who need automatic door integration done right the first time

If keeping your doors working is your problem, it's our job.
