The parts that actually fail

Door Hardware Service in Charlotte, NC

Describe what the hardware is doing, not what you think it needs.

Nearly all of it is adjustment

Hardware complaints arrive as replacement requests. The door slams, so the closer is broken. The door will not latch, so the lock is broken. The exit device rattles, so the exit device is broken.

In practice a large share of these are adjustments, and a further share are alignment problems where the hardware is fine and the door has moved. A closer that slams has usually had its sweep valve backed off by somebody who wanted the door to shut properly in winter. A door that will not latch has usually dropped an eighth of an inch on a worn top hinge and is now presenting the latch bolt below the strike opening.

None of that is exotic. It is just that nobody looks, because looking takes a technician and replacing takes a purchase order, and a purchase order is easier to get.

Scope

Hardware, condition, and what the standards require

Two standards families do most of the work here. ANSI/BHMA A156 grades hardware by tested cycle life and performance, and matching grade to traffic is the difference between a five-year opening and a fifteen-year one. The ADA 2010 Standards govern how the finished opening has to behave: section 404.2.9 caps interior hinged doors at 5 lbf to open, 404.2.8.1 requires a closer to take at least five seconds from 90 degrees to 12 degrees from the latch, and 404.2.7 puts operable hardware between 34 and 48 inches above the floor. Fire doors are exempt from the 5 lbf figure because they need enough force to latch positively, and should be set to the minimum the authority having jurisdiction allows.

Door closers

Sweep, latch, backcheck, and spring size. Most closers on a service call need adjustment and a correct spring size for the door, not replacement.

Exit devices

Rim devices, mortise devices, and both surface and concealed vertical rod configurations. Dogging, latch retraction, and rod adjustment. On a rated assembly the device has to be listed for fire door use and cannot be dogged.

Locksets and cylinders

Cylindrical, mortise, and interconnected. Lever function, spindle wear, and cylinder condition.

Hinges and pivots

Where a surprising proportion of latching and binding complaints actually originate. A worn top hinge drops the leaf, and everything downstream reports it as a lock fault.

Strikes and alignment

Latch to strike relationship, keeper depth, and frame condition at the strike. Adjustment here fixes more doors than any part on this list.

Thresholds, sweeps, and weatherstripping

Air, water, and light control at the perimeter, and on rated assemblies the smoke and intumescent seals that carry a compliance function rather than a comfort one.

Kick plates and protection plates

Ordinary on a standard door. On a rated assembly the plate has to be listed and there are limits on size and placement, which is a detail that gets missed constantly.

Hardware service, how it is billed

Category	Basis	Typical outcome
Adjustment visit	Labor only	Multiple openings corrected in one trip
Like-for-like replacement	Parts plus labor	Same grade or better, matched to traffic
Grade upgrade	Parts plus labor, higher parts cost	Recommended where traffic outran the original spec
Listed product for rated openings	Parts plus labor, lead time varies	Non-negotiable on a rated assembly

Buildings with more than a handful of openings usually do better on a scheduled adjustment pass than on individual reactive calls, because closers and strikes drift on a predictable timescale and get caught before they become latching failures.

How we work it

How a hardware call runs

01

Describe the behavior

What the door does, when it started, and whether anything changed around it. Call (333) 333 333
02

Read the opening

Hinges, leaf position, strike relationship, closer settings, frame condition. In that order.
03

Adjust, then decide

Where adjustment holds, that is the repair. Where it will not, the part and the reason both get named.
04

Verify against spec

Sweep timed, force checked where applicable, latching confirmed from full open. Then written up.

Why us for this

What you get that you would not get elsewhere

Adjustment attempted first

Sweep, latch speed, spring size, strike alignment, hinge condition. Replacement follows only where adjustment genuinely will not hold.

Grade matched to traffic

ANSI/BHMA grading exists for a reason. Fitting light-duty hardware to a high-cycle opening produces a repeat call at your expense, not ours.

Set to the numbers, not by feel

Closer sweep timed against the ADA five-second minimum, opening force checked with a gauge where the 5 lbf limit applies rather than estimated by pulling on the door.

Rated openings restricted deliberately

Listed hardware only, no dogging on fire exit devices, and plate sizes kept inside what the listing permits.

The hinge gets checked

Because half the latching complaints in this trade are a leaf that dropped.

Talk it through before anybody quotes it

One opening or forty. Describe the behavior and we will tell you whether it is an adjustment.

Scoping call, no charge. A number given before anyone has measured the frame is a guess wearing a suit.
