A commercial door can look fine at a glance and still be a major problem behind the hardware.
If your hinges are pulling, your latch doesn’t catch consistently, your door drags, or your closer fights the door every time it shuts, the issue often isn’t the hardware — it’s the fit. And when the fit is off, you get premature failure, recurring service calls, and doors that don’t pass inspection.
That’s where professional door mortising matters.
At ABC Construction, we provide expert door mortising throughout Thornton and surrounding areas, helping facility managers, property managers, and contractors get doors that close smoothly, latch properly, and stay aligned under heavy traffic.
Mortising is the precision cutting and routing of a door and/or frame so hardware sits correctly — flush, aligned, and operating exactly the way it was engineered.
When mortising is rushed or done inaccurately, the ripple effects show up fast:
Loose hinges and sagging doors that worsen every week
Strike alignment issues that cause inconsistent latching and lock failure
Damaged door edges that reduce the life of the door (and can affect fire ratings)
Closer and panic hardware problems caused by poor alignment and uneven tension
Repeat service calls because the real issue was never fixed
In commercial spaces, doors take a beating. High-traffic use exposes any small inaccuracy — and that’s why mortising needs to be done right the first time.
Generic maintenance crews often don’t have the tools, templates, or commercial hardware experience to mortise accurately — especially for heavy-duty hardware and code-required devices.
ABC Construction specializes in commercial-grade door systems, including the exact mortising requirements for:
Hinges and continuous hinges
Locksets and latch prep
Panic hardware and exit devices
Door closers
Flush bolts
Electric strikes and access control prep
ADA-related hardware positioning
Fire-rated door and frame hardware prep
We don’t just “cut it until it fits.” We align hardware to proper clearances, door swing requirements, and the realities of commercial use — so your door operates smoothly and securely for the long haul.
Door mortising often has to happen in real-world conditions — while tenants are present, deliveries are moving, staff is working, and entrances need to stay functional.
That’s why our approach is designed around precision and minimal disruption.
Experienced commercial door technicians (not general handymen)
Accurate mortising for proper alignment and hardware performance
On-site corrections and repairs for doors that were prepped incorrectly
After-hours availability when downtime isn’t an option
Commercial-grade tools and templates for consistent, repeatable results
Documentation and clear communication so you’re not guessing what was done
If you’re tired of doors that “almost work,” this is the permanent fix that restores confidence in your building’s security and compliance.
Door mortising is the right move when:
You’re installing new commercial doors and hardware needs to be prepped correctly
A door is dragging, sagging, or not latching, even after adjustments
Hardware keeps failing prematurely (hinges, latch, closer, or panic bar)
You’ve inherited a building where doors were “patched together” over time
You need to correct alignment for ADA compliance
Your doors are failing inspection due to egress issues or hardware misfit
If the hardware isn’t sitting flush and aligned, the door will never behave the way it should — and neither will the people trying to use it.
Mortising is one of the smallest details in door work — and one of the biggest causes of recurring problems when it’s done wrong.
Here’s how to get started:
Schedule a Door Assessment
We evaluate the door, frame, and hardware alignment, and identify the root cause.
Get a Clear Scope and Plan
We outline what needs to be mortised, repaired, or replaced — with straightforward pricing.
We Complete the Work With Minimal Downtime
Our team handles the prep, installs or re-installs hardware correctly, and tests operation thoroughly.
Optional Ongoing Maintenance Support
Prevent future misalignment and hardware failure before it becomes an emergency.
For critical security issues, we offer emergency response within 2 hours throughout Thornton and surrounding areas. Our mobile service vehicles are fully equipped with common commercial hardware components, allowing us to resolve many issues on the first visit without waiting for parts to arrive.
We are certified installers for all major commercial door hardware manufacturers including Schlage, Von Duprin, LCN, Dorma, and Yale. Our established relationships with these manufacturers ensure we can source parts quickly and provide warranty-backed installations that meet all manufacturer specifications.
Absolutely. We specialize in after-hours installations and repairs to minimize disruption to your business. Our technicians are trained to work efficiently in occupied buildings, using containment procedures to limit noise and dust while maintaining security throughout the repair process.
We handle all aspects of commercial door hardware including closers, hinges, pivots, locks, exit devices, automatic operators, and electronic access control integration. Our expertise covers everything from basic storefront applications to high-security solutions for sensitive areas requiring controlled access.
This depends on several factors including the age of the hardware, availability of replacement parts, and the overall condition of the door. During our assessment, we provide honest recommendations based on long-term cost-effectiveness rather than pushing for unnecessary replacements, often saving clients compared to complete hardware replacement.
