(984) 398-5248What this company actually does
Everything below is service work on pedestrian openings — doors that already exist, in buildings that are already occupied. Maintenance rounds, leaves that have stopped behaving, perimeter seal and thresholds, hinges and pivots, and the door items that hold up a construction handover.
What is not here is as informative as what is. No overhead or coiling doors, no dock equipment, no vehicular gates, no new openings cut into walls. Those are separate trades with separate qualifications and we are not going to pretend otherwise to keep a job on the books.
Start from what the door is doing
Pick the behaviour that matches. Each one lists the causes we actually check for, and which line of work it usually turns into.
Closes but will not latch
Almost never the lock, despite how it reads from the handle.
- Strike misalignment
- Hinge screw pull-out
- Frame out of square
- Closer over-adjustment and arm geometry
Handled under door alignment and drag correction.
Catches or drags on the frame
Eight causes are in play here, and they separate by measurement rather than by eye.
- Hinge screw pull-out
- Frame out of square
- Floor movement and slab settlement
- Leaf warp and twist
- Closer over-adjustment and arm geometry
Handled under diagnosing a binding leaf.
Heavier to open than the others
Worth ruling the building out first: if it changes when the air handling stops, the opening is not the fault. On interior openings ADA 2010 Standards section 404.2.9 caps opening force at 5 pounds.
- Closer over-adjustment and arm geometry
- Weatherseal and gasket interference
- Floor movement and slab settlement
- Air pressure across the opening
Usually alignment and closer adjustment, or perimeter seal and gasketing when the resistance runs around the whole perimeter.
Slams shut
Sweep speed and latch speed are separate valve settings. Slamming is normally one of those, or lost fluid.
- Closer function across the full swing
Picked up on a scheduled service round.
Daylight, draught or water at the edge
Check it from inside with the lights out. On labelled openings this stops being a comfort question.
- Head and jamb weatherstripping
- Door bottoms and sweeps
- Thresholds and saddles
- Meeting stiles and astragals on pairs
Handled under weatherseal, thresholds and sweeps.
Sagging at the latch corner
The gap tapers — tight high on the lock side, wide low on the hinge side.
- Screw pull-out and hole repair
- Butt hinge replacement
- Continuous hinge retrofit
Handled under hinge and pivot service, once a frame and alignment check has ruled the frame out.
The same fault keeps coming back
Repeat repairs usually mean a condition underneath that nobody has corrected.
- Frame out of square
- Closer over-adjustment and arm geometry
- Floor movement and slab settlement
This is what planned maintenance exists to stop.
New build, not right at handover
Closers get set before the carpet, the gasketing and the air handling exist.
- Closer setting across every opening
- Hardware against the schedule, opening by opening
- Label and rated assembly check
- Egress function on required openings
Handled under punch list and turnover work.
This narrows a phone call. It does not replace a visit — several of these causes look the same from the doorway and only separate under a level and a gauge.
The five lines of work
Commercial Door Maintenance Plans
Recurring visits that walk every opening in the building, adjust what is drifting, and leave a written list of what is not.
Read the detailDoor Alignment and Drag Correction
Leaves that catch the frame, scrape the floor, or will not latch without a shove — diagnosed at the frame before anything gets adjusted at the door.
Read the detailWeatherseal, Threshold and Sweep Replacement
Perimeter seal, door bottoms and thresholds on exterior openings — the line item that shows up on the energy bill rather than the maintenance one.
Read the detailDoor Hinge and Pivot Service
Hinges, continuous hinges and offset pivots — replaced or corrected once the frame has been checked, because sagging leaves are rarely only a hinge fault.
Read the detailPunch List and Turnover Door Service
Closing out door and hardware items at the end of a build — adjustment, correction and verification against the door schedule before handover.
Read the detailOne city, on purpose
All five lines run inside Charlotte only. The round is what makes the rest of it work, the round needs short drives, and short drives mean the city rather than the metro. It is the same decision twice.
