This is the equipment around the opening — the parts that take the hits, keep the weather out, and let people see what they're doing. It's also the equipment most often bought from a catalogue and never actually serviced. This page is about getting it looked at.
Which piece of dock equipment is it?
| What it is | How you can tell | What typically fails | Repaired, or replaced? |
|---|---|---|---|
| Dock seal | Compressible foam pads in fabric, mounted around the opening, that the trailer presses into | Fabric torn or worn through, foam collapsed, fixings pulled out of the wall, head pad sagging | Small tears and head curtains are often repairable. Collapsed foam and pulled fixings usually mean replacement of that section |
| Dock shelter | A fabric hood or canopy on a frame that the trailer backs under, with side curtains | Fabric torn, stays or frame bent, corner damage from a missed approach | Fabric and stays are often replaceable; a bent frame is a bigger assessment |
| Inflatable shelter | A shelter that inflates around the trailer after it parks | Blower, bladder, seams, controls | Blower and controls are serviceable; bladder damage depends on where and how big |
| Dock bumper | Black rubber blocks bolted to the dock face at trailer-bed height | Crushed flat, split, missing, hanging by one fixing, torn off with the anchor | Bumpers are consumable. Almost always replaced, not repaired |
| Dock light | A jointed lamp on a swing arm beside or above the opening | Lamp, head, arm joints, switch, cord, circuit | Heads and arms are replaceable; a dead circuit is electrical work |
| Wheel chocks | Wedges placed under the trailer wheels, often on a chain or in a holder | Cracked, worn smooth, missing, chain broken | Replaced |
| Dock ladder and handrail | A fixed ladder in the dock face or a rail at the edge | Loose fixings, bent rungs, corrosion, damage from a trailer | Assessed structurally, not patched casually |
| Corner and jamb guards | Steel angle protecting the opening corners | Bent, torn away, taking damage that should have gone to a bumper | Replaced, and usually a sign the bumpers behind them are gone |
Call and describe what's damaged.
Seals and shelters
A seal and a shelter do the same job two different ways, and they aren't interchangeable.
A seal uses compressible pads mounted tight around the opening. The trailer backs into them and squashes them. It gives the tightest weather seal, but it only suits a narrow range of trailer sizes, and every approach wears the fabric.
A shelter uses a frame with fabric curtains that the trailer backs under. It handles a much wider range of trailer sizes and it's more forgiving of a bad approach, but it seals less tightly.
That difference explains most of the damage a provider sees. A seal fitted where trailer sizes vary a lot gets torn at the edges. A shelter in a tight opening gets caught. When a seal keeps failing in the same place, the useful question isn't "can you patch it again" — it's whether the right equipment is on that opening.
What gets inspected: the pad fabric and wear pleats, the head pad or head curtain, the backing and its fixings into the wall, the frame on a shelter, the side stays, and the condition of the wall or dock face behind the mounting. Fixings pulling out of a wall are usually telling you something about the wall, not the seal.
What to report: where it's torn, how big, whether anything has pulled away from the building, and whether the trailer still seals well enough to work the bay.
Bumpers
Dock bumpers are consumable. They exist to be destroyed slowly so the building isn't destroyed quickly.
When bumpers are crushed, split or missing, trailer impact goes into the dock face, the leveler's structure, the seal mounting and the jambs instead. That's the reason to replace them on a schedule rather than after the wall cracks. Laminated bumpers wear down in layers, moulded bumpers split or compress, and steel-faced bumpers move the wear to a plate that can be replaced.
What gets inspected: remaining thickness, the mounting bolts and the anchors behind them, the dock face concrete, and whether the trailer is actually landing on the bumpers or above or below them. A bumper at the wrong height protects nothing.
What to report: how many are crushed, missing or hanging, on which positions, and whether the concrete behind them looks damaged. If it does, say so — that's a different trade and you'll want to know early.
Lights, chocks and the rest
Dock lights. A jointed arm lamp gets hit, twisted and pulled more than almost anything else on a dock. Heads, arms, switches and cords are replaceable. If the circuit itself is dead, that's electrical work, and in North Carolina that means an electrical licence — see below.
Wheel chocks. These are not optional equipment, and they aren't replaced by a powered restraint. 29 CFR 1910.178(k) requires that the brakes of highway trucks be set and wheel chocks placed under the rear wheels to prevent the truck rolling while it's boarded by powered industrial trucks, and paragraph (m)(7) repeats that brakes be set and wheel blocks in place while loading or unloading. If your chocks are cracked, worn smooth or missing, replace them. And worth stating plainly, because it's widely assumed the other way: OSHA does not mandate a powered vehicle restraint anywhere. The requirement is positive protection against movement. More on restraints
Ladders, handrails and guards. Fixed dock ladders, edge handrails and corner guards get assessed as structure, not as accessories. Loose fixings in a dock face are a finding worth acting on.
What we cover — and what we don't
Covered: dock seals, dock shelters and inflatable shelters; dock bumpers and their mountings; dock lights and arm lights; wheel chocks; dock ladders, handrails and corner guards — at commercial and industrial buildings.
Not covered, and who to call: installed dock levelers (this page); portable dock plates and boards (this page); vehicle restraints, dock locks and communication lights (this page); the door in the opening (overhead, roll-up, high-speed or fire-rated); dock face concrete, slab and structural repair (a commercial concrete contractor); parts-only orders (the manufacturer or a distributor); boat docks (a marine contractor).
What to say when you call
Example wording: "Two bumpers are gone on bay 6 at our distribution building in Raleigh and the seal is torn on the same door."
That's an example of how to open the call — not a real job and not a script.
Helpful if you have it: how many positions are affected, the approximate opening size, whether it's a seal or a shelter, and site access. You can call without any of it.
What happens after you call
You describe the equipment, the damage and the facility location. Your request may then be shared with an independent commercial dock-and-door repair company working in this area. That company confirms availability, scope, pricing and its own terms with you.

What affects the price
| Driver | Why it moves the price | What to ask |
|---|---|---|
| Call-out or diagnostic fee | Assessing seals and shelters means getting to the top of the opening | Is there a fee, what does it cover, is it credited? |
| How many positions | Dock equipment is usually a multi-position job, and that cuts both ways on price | What's the price for one position versus all of them? |
| Seal or shelter, and which type | Pad seals, head curtains, frame shelters and inflatables are different products and different labour | Which is right for this opening, and why? |
| Fabric and pad specification | Materials vary in wear life and cost | What material are you quoting, and what's its wear life? |
| Bumper count and mounting condition | The bumper is cheap. Damaged anchors and concrete are not | Are the anchors and dock face sound? |
| Electrical work on lights | New power or controls is electrical contracting in NC, with no dollar threshold | Who does the electrical part, and what licence? |
| Dock face condition behind the equipment | If the concrete is damaged, that's a different trade before this work makes sense | Is there concrete work needed first? |
| Access and taking positions down | Positions out of service, lifts, hours | How long is each position down? |
| Parts lead time | Seals, shelters and specific bumper profiles are usually made to order | What's stocked, what's ordered, and what date? |
We can't quote your exact dock equipment work from a web page. The price depends on the equipment, how many positions, what's behind the mounting, and how the openings are reached. Here's what to ask before you authorize work: whether the number is a call-out fee, a starting price, a scoped fixed price, an estimate or a final quote; what's included — labour, materials, access equipment, travel, and any return trip for made-to-order items; and what happens if the dock face behind the equipment turns out to need work.

The North Carolina rules that affect this work
North Carolina runs its own OSHA programme, but the Department of Labor states it adopts federal OSHA standards verbatim with certain exceptions, and none of the state-specific standards touches dock equipment or powered industrial trucks (NC DOL). So the federal chocking and securing rules above apply here as written.
On the electrical side of dock lights and communication systems: North Carolina requires an electrical contractor licence with no dollar threshold (N.C.G.S. § 87-43), and the only minor-work exemptions in the statute are lamps, fuses and cord-connected appliances (§ 87-43.1). Replacing a lamp is one thing. Running a new circuit to a dock light is another.
On permits: the statute exempts work costing $40,000 or less with six carve-outs, one of which is a change to electrical system design (§ 160D-1110(c)). The homepage rulebook lists every permit office in this metro with its portal.

Questions about dock equipment repair in Raleigh–Durham
What's the difference between a dock seal and a dock shelter? A seal uses compressible pads the trailer squashes against — tightest weather seal, narrowest range of trailer sizes. A shelter uses a frame and curtains the trailer backs under — wider range, more forgiving, less tight. If a seal keeps tearing in the same place, the real question may be whether it's the right equipment for that opening.
How do I know when bumpers need replacing? When they're crushed flat, split through, hanging, or missing. Also when the trailer is landing above or below them, because a bumper at the wrong height isn't protecting anything. If the concrete behind them looks damaged, mention it — that's a different trade.
Are wheel chocks still required if we have a trailer restraint? 29 CFR 1910.178(k) requires brakes set and wheel chocks under the rear wheels of a highway truck being boarded by powered industrial trucks, and (m)(7) repeats it. OSHA doesn't mandate a powered restraint anywhere — it requires positive protection against movement. Your facility's own procedures decide how that's met.
Can a torn dock seal be patched? Sometimes. Small tears and worn head curtains are often repairable. Collapsed foam, torn backing and fixings pulled out of the wall usually mean replacing that section — and the fixings failing is often a message about the wall.
