Charlotte only, by design
Commercial Doors and Door Hardware Service in Charlotte, NC
Say where the opening is in the building and how hard it gets used.
Cycle load estimator
Turns your own traffic estimate into an annual cycle count and compares it against the tested cycle ratings published in ANSI/BHMA A156.4 (closers) and A156.3 (exit devices).
Pick a position and a traffic band. The arithmetic and the reference figures this estimator applies are printed in full directly below.
| Standard | Grade 1 tested cycles | Covers |
|---|---|---|
| ANSI/BHMA A156.4 | 2,000,000 | Door closers |
| ANSI/BHMA A156.3 | 500,000, with a preload applied to the door | Exit devices |
| Position | Usual first consumer |
|---|---|
| Lobby vestibule | Closers fighting wind and stack pressure; the two door lines interact as one assembly |
| Kitchen or service pass | Pivots and double-acting hardware, plus impact at the bottom rail |
| Stair door | Closer arm geometry and the strike — it has to latch by itself every time |
| Dock personnel door | The bottom eight inches of leaf and frame — weather and impact more than cycles alone |
| Suite entry | Latch and lever wear at mid-band traffic |
| Stockroom door | Hinge sag from cart traffic, showing up first as a strike that no longer lines up |
Arithmetic: annual cycles = the midpoint of your traffic band × operating days; the five-year figure is that times five. The site's working rule: more than a few hundred passes a day is a high-cycle opening. This is an estimate for a specification discussion, not a measurement, and tested cycle ratings are laboratory figures, not a promise about any particular opening.
The door that fails is almost never the oldest one
Walk a building with somebody who has been maintaining it a while and they will point at the doors they worry about. Nine times in ten they point at the old ones. The leaf with the chipped paint, the frame from whenever the building went up, the closer that has been there longer than they have.
That instinct is wrong, and it is wrong in a way that costs money. A commercial door does not wear out on a calendar. It wears out on a cycle count. An opening between a service corridor and a dining room in South End can take twelve hundred swings in a Saturday. The mechanical room door twenty feet away might take four hundred in a year. Same building, same hardware schedule, same annual walkthrough, and a difference of two orders of magnitude in what is actually happening to the hinges.
So we organise by where the opening sits and what goes through it, not by what it is made of and not by how old it is. That is the whole idea. It decides which pages exist on this site, it decides what is on the truck on a Tuesday, and it is the reason this outfit works one city instead of six counties.
Run by somebody who spent years arriving without the right part
Merritt Kanipe worked multi-site door and hardware calls for a national facilities vendor across both Carolinas. The work order would say the closer was leaking. It would not say whether the closer was a surface-mounted unit on a hollow metal leaf or a concealed floor closer under an aluminum entrance, because nobody had ever written that down, and the person who dispatched it was three states away.
The pattern was always the same: drive out, look at it, drive back, order the part, drive out again. Two visits, one repair, and a customer who had a door tied open for nine days. Charlotte Commercial Door Service exists to make the first visit the only visit, and the way to do that is to know a finite set of buildings well enough that the part is already in the van.
Sorted by where the opening sits
Commercial Door Services in Charlotte
Six lines, sorted by where the opening lives rather than by what it is made of. An entrance behaves differently from a dock door even when the two are the same steel leaf from the same manufacturer, because one gets wind and public hands and the other gets carts and weather and a forklift that came too close. The sixth line is the exception to the rule: hardware that high-cycle openings consume, regardless of which door it is bolted to.
Entrance and Vestibule Door Service
The doors the public uses, which take more cycles in a month than most openings take in a year.
Glass Door and Patch Fitting Service
All-glass and narrow stile entries, floor closers, patch fittings and the pivots underneath them.
Loading Dock Personnel Door Service
The man door beside the dock — the one that takes the weather, the carts and the corner of every pallet.
Stairwell and Cross-Corridor Door Service
Labelled openings that have to close and latch on their own, every time, without anybody thinking about them.
Back-of-House Door and Hardware Service
Kitchen passes, stockroom doors and service corridors — the highest-cycle openings in almost any building.
High-Traffic Hardware Replacement
Closers, exit devices, locksets and hinges on openings that consume hardware rather than merely using it.
Why the whole opening gets looked at, not just the part that broke
A commercial opening is five things bolted together: a leaf, a frame, hinges, a closer, and whatever holds it shut — a lockset on most doors, an exit device on the ones people have to get out through. Those five load each other. Change one and the other four feel it, which is why a door that has been put right three times is usually a door where the wrong one of the five was put right each time.
The frame is the datum
If the anchors have loosened in the wall, or the leaf has lost its flatness, every adjustment made to the hardware is being made against a moving reference and none of it holds. Ruling the frame out is the first step here and it is the step most often skipped elsewhere.
Hinges decide where everything else sits
Butt hinges wear at the barrel and open up their screw holes, and the leaf drops. A dropped leaf drags at the strike edge, carries the latch out of line with the strike, and makes the closer look faulty when it is only being asked to lift a door it was never sized to lift.
A closer has to leave energy for the latch
Sweep, latch speed and backcheck are one adjustment problem, and the closer still has to drive the latch home at the end of the stroke. Undersized against wind or a pressure difference across the opening, it will close the door and still fail to latch it.
Locks and exit devices fail differently
A lockset holds a door shut. An exit device does that and also has to release under a single motion from the inside, which is a different mechanism with different failure modes. Both depend on a strike that is still where somebody fitted it.
Which of the five is at fault decides everything downstream. For the symptom-first version — a door that will not latch, one that drags by mid-afternoon, a pair that closes out of order — start with what a service call actually checks. Where the part that keeps failing is hardware rather than the door itself, closers, locksets and exit devices covers grades, rebuilds and panic hardware. And where a leaf or frame is past adjusting, fitting a new entrance door and frame is the conversation instead.
Why the map stops at the city line
There are no service area pages on this site and there is no list of towns in the footer, which for a local trade website is unusual enough that it is worth explaining rather than leaving as an absence.
The argument is about inventory. A van carries a finite number of parts. Which parts to carry is a bet, and the bet only pays off if the building stock is small enough to learn — the aluminum entrance systems that went into Uptown and South End in a particular decade, the hollow metal that Freedom Drive and the Yorkmont corridor were built with, the storefront that every strip centre off South Boulevard uses, the abuse that a University City student union takes in October. Stretch that across a six-county metro and the bet stops predicting anything. You end up a courier for a supply house, which is precisely the job Merritt left.
So the answer to whether we come out past the ring towns is no. Not this quarter, not as a favour, not for a good customer with a second site. Somebody closer to that building will do it better, and if you ask on the phone we will usually know who.
Why buildings keep the number
The first question is where the door is, not what it is
A leaf between a kitchen and a dining room, a stair door on a fire-rated wall, a dock man door, a suite entry off a lobby — those four openings fail in four completely different ways and consume four different sets of parts. Naming the location tells us more in five seconds than a photograph does in five minutes.
Parts on the truck, chosen for one city
Closers in the sizes Charlotte's stock actually uses, cylindrical and mortise lock parts, exit device rebuild kits, continuous hinges, top and bottom patch fittings for glass, thresholds, sweeps, strikes and the fasteners that go with all of it. Not everything. The things that fail here.
Cycle counts get talked about honestly
Hardware is graded on tested cycles. ANSI/BHMA A156.4 Grade 1 closers are tested to two million cycles, A156.3 Grade 1 exit devices to five hundred thousand with a preload applied to the door. Those numbers are not a warranty and they are not a promise about your opening. They are a way of working out whether the hardware on a door was ever the right grade for the traffic it gets, which is the actual question behind most repeat failures.
Three people, and you get all three of them
No dispatch centre, no ticketing portal, no account manager who has never seen the building.
Where the lane ends is stated plainly
Automatic and power-operated entrances, overhead sectional and coiling doors, and certified fire door inspection reporting are not what this outfit does. Those are named on the pages where you would reasonably assume otherwise, because finding out on the day helps nobody.
Questions worth settling before you call
What counts as a high-cycle opening?
There is no official threshold, and anybody who quotes you one is making it up. As a working rule, if more than a few hundred people pass through an opening on a normal day — a lobby vestibule, a restaurant service door, a corridor between a sales floor and a stockroom, a stair door in an occupied office tower — treat it as high cycle and expect hardware to be a consumable rather than a fixture.
Do you only work in Charlotte proper?
Yes. Not the county, not the ring towns, not across the state line.
Can you tell me what is wrong over the phone?
Often we can narrow it to two or three things, which is usually enough to bring the right parts. Where the opening is, what changed recently, whether it still latches on its own, and whether the problem is worse in the afternoon than the morning — that last one sounds odd and it is one of the more useful questions, because a door that only drags when the building is warm is telling you about the frame rather than the hinges.
Is this maintenance-contract work or one-off calls?
One-off calls. Somebody phones because a door is doing something it should not, we come and sort it. If a building wants a scheduled programme with paperwork attached, that is a different kind of outfit and we will say so.
Do you do automatic doors?
No. Sliders, swing operators and anything with a sensor header belongs to a contractor who works on those daily and carries the right training for them. If your vestibule has manual doors on one line and an operator on the other, we take the manual line and you keep the automatic contractor for the rest.
What about the big overhead door at the dock?
Also no. Sectional and coiling doors are a separate trade with separate tooling and separate risk. The personnel door beside the dock, the one people actually walk through, is very much ours.
Our fire doors need inspecting. Can you do that?
We can service them, adjust them and replace hardware on them. What we do not do is issue the annual inspection record NFPA 80 requires — that wants an inspector whose qualification the authority having jurisdiction will accept, and it is a documentation product rather than a repair. We will tell you when something we are looking at would fail that inspection, which is worth knowing before the inspector arrives rather than after.
Why is there no pricing on this site?
Because the same symptom on two openings can be a fifteen-minute adjustment or a leaf and frame replacement. Publishing a figure would mean publishing a figure for a door we have not seen.
Do you work in occupied buildings during business hours?
Most of the work happens that way. Some of it should not — a corridor pair in a hospital wing or a main entrance at a restaurant during service is better scheduled around the building's day. That changes the figure and you hear by how much before agreeing to it.
