Commercial Door Repair in Nassau County

We service automatic sliding and swing doors, aluminum storefront entrances, hollow metal and steel security doors, fire-rated door assemblies, and interior commercial doors, along with the closers, panic hardware, locks, and sensors on them. We do not service rolling steel, roll-up, loading-dock, or high-speed doors.

We offer priority emergency service for commercial clients because a malfunctioning door can halt operations and compromise security. In most cases we can have a technician on-site within a few hours of your call, and we carry common commercial parts on our vehicles to resolve issues quickly.

A maintenance visit checks the things that wear on a schedule rather than waiting for them to fail. We measure closer force and closing speed, check hinges and pivots for play, test sensors and safety circuits, cycle locks and exit devices, clean and lubricate tracks and running gear, and inspect seals and thresholds. Anything out of spec gets adjusted on the visit, and anything needing a part gets quoted. You keep the written report.

Yes, we offer customizable preventive maintenance programs that include scheduled inspections, lubrication, adjustment, and testing of all door components. Regular maintenance extends the life of your door systems, reduces emergency repair costs, and keeps fire and safety codes covered.

Both. Most commercial door problems are a hardware or alignment fix and we repair them on site. When a door is bent, corroded, or cycled past its service life, repairing it just buys a few months, so we quote a replacement instead: slab only, slab and frame, or the full assembly with new hardware. We tell you which one you are looking at after we see the door, never before.

No, and it is worth being clear about the difference. The annual NFPA 80 inspection has to be signed off by a qualified fire door inspector, and we are not that. What we do is the repair work an inspection turns up: closers that no longer latch the door, damaged or painted-over hardware, bad clearances, failed seals, and labels or hardware that were replaced with the wrong part. Send us the deficiency list and we will quote the fixes.

Yes. We test opening force, adjust closing speed and hold-open timing, check threshold height, and set sensor ranges and activation controls to meet ADA standards, then document what we changed. Where the existing operator cannot be brought into spec, we replace it with one that can.

We schedule replacements and major repairs during off-peak hours, evenings, or weekends whenever possible. For work that must happen during business hours, we stage materials in advance, use temporary barriers for safety, and communicate clear timelines so your staff and customers are informed throughout.

Minor adjustments and sensor recalibrations typically start at a lower price point, while motor replacements or full panel repairs cost more.
