Commercial mobile-door help
D&L provides a clear starting point for box truck and trailer roll-up door repair, maintenance, operational inspection, and replacement planning. The door, vehicle opening, counterbalance system, tracks, rollers, latches, and seals must be identified together before the right scope can be quoted.
On-site inspection
$89
Find your next step
Choose a repair path, plan a replacement, or identify the door before discussing parts. These guides concern the rear roll-up cargo door on a truck or trailer.
Operational inspection of door travel, balance, tracks, hardware, latches, seals, and visible damage.
Planned care for tracks, rollers, counterbalance parts, latches, seals, and door movement.
A practical guide to identifying the door, model, serial information, and compatible replacement parts.
Understand the problem
A delivery truck door is worked at every stop. A trailer door may also face dock impacts, shifting loads and weather. Tell us which vehicle and door you have so we can review the right repair, replacement or maintenance approach.
01
A door that gets heavier, jerks through the curve or will not stay in position needs a complete movement check. Springs and cables support the load; rollers, hinges and tracks guide it. Replacing one part without checking alignment can leave the original cause unresolved.
Truck roll-up door repair02
Our truck-door service concerns the rear roll-up cargo opening, including panels, latches, tracks and counterbalance hardware. It is not cab-door, engine or vehicle-body repair. Share the trailer type and full opening before arranging service, particularly when the door or surrounding frame has impact damage.
Door condition inspections03
Panel construction and perimeter seals matter when the cargo opening needs insulation or weather protection. Identify the original door and intended use before choosing replacement parts. A door repair does not include refrigeration-unit repair or certify cargo temperature performance.
Plan a replacement door04
Prepare a vehicle list with unit numbers, door types, reported faults and service history. Group inspections around vehicles that can be taken out of service. A condition review separates routine care from damaged hardware that needs an approved repair and quote.
Fleet door maintenanceSystems, products & scope
Use the narrower page that best fits the door condition and the decision you need to make.
01
Focus on the diagnosed mechanical, hardware, latch, or door problem.
02
Build a practical condition review around fleet use and observed wear.
03
Gather measurements and equipment information before choosing a replacement path.
Equipment compatibility, available parts and the installation scope are confirmed before ordering or approving work. Bring model information and photos to the service conversation.
Know what you are booking
The door, vehicle opening and supporting hardware work as one system. Checking alignment, wear and equipment identification helps distinguish a part failure from wider damage before a repair is quoted.
Truck & trailer roll-up door inspection
$89
The $89 charge covers the on-site inspection, not repairs or replacement parts. Confirm access, location and applicable charges when scheduling. Ask the shop to confirm in-shop inspection pricing.
Keep clear of a heavy or unsupported door. Do not release, adjust, or remove counterbalance parts, cables, springs, or a loaded door. Park safely, keep the opening clear, and call when the door cannot be supported or secured.
Repair or replace?
The best starting point depends on whether the problem is isolated, recurring, fleet-wide, or structural.
A repair can fit when the door and opening remain serviceable and the failed scope can be identified.
Maintenance and operational inspections can help document condition and address wear before routing a separate repair.
Replacement needs accurate measurements, operating details, and confirmation that the surrounding opening can support the selected system.
Make the visit productive
Please plan to leave your truck or trailer with us for several hours for an in-shop inspection. This allows time to assess door travel, counterbalance hardware, tracks, rollers, latches and the surrounding opening, and identify the parts needed. Several hours is an inspection planning allowance, not a promise that repairs will be completed that day. Confirm drop-off arrangements, vehicle access and collection timing with the shop before arrival.
6701 SE Foster Rd, Unit D, Portland, OR 97206
The showroom is at the back of the building near 67th Avenue and SE Foster Road. Enter the parking lot from 67th Avenue. Confirm vehicle dimensions, turning space and drop-off arrangements before bringing a truck or trailer.
3800 W Chinden Blvd, Boise, ID 83714
The showroom is near 38th Avenue and W Chinden Boulevard. Parking-lot access is from 38th Avenue. Confirm vehicle dimensions, turning space and drop-off arrangements before bringing a truck or trailer.
Before you book
Inspection costs, preparation, equipment and next steps. Tell us about your specific vehicle and cargo door when you call.
An on-site truck or trailer roll-up door inspection is $89. An on-site assessment of the cargo door, counterbalance hardware, tracks and securing components. The $89 charge covers the on-site inspection, not repairs or replacement parts. Confirm access, location and applicable charges when scheduling. Ask the shop to confirm in-shop inspection pricing.

No. The inspection establishes the condition and recommended scope. Repair labor, replacement parts and installation are quoted separately for approval. Confirm any applicable tax, travel or urgent-service charges when booking. Ask about inspection-fee terms before authorizing service.
The supported family includes box truck and trailer roll-up door requests. D&L still needs the vehicle, door, location, and requested scope to confirm current availability.
No. Keep clear of an unsupported or uneven door and do not adjust cables, springs, or counterbalance hardware. Call with the vehicle and door condition.
D&L can use labels, model or serial information, opening measurements, hardware details, and photos to investigate the equipment path. Identification and parts availability are confirmed case by case.
No. This page describes an operational condition review for service planning, not a legal, regulatory, fleet-safety, or compliance certification.
D&L handles truck and trailer roll-up cargo-door requests. Share the trailer, door manufacturer, dimensions, condition and location so the team can confirm the service scope and parts path. This does not include truck cab doors or vehicle bodywork.
A readable door label or serial plate, full-door photo, opening dimensions and close-ups of the affected hardware help identify the system. The truck chassis brand alone is not enough. These are examples of door makes described on D&L’s legacy service pages; compatible parts and current availability are confirmed for the specific door.
Call first and describe whether the door is stable, can be secured and is blocking cargo access. Do not drive with an unsecured or unstable door. The team can discuss access and available service options before you move the vehicle.
Diagnose a truck or trailer roll-up door that is stuck, crooked, damaged, or difficult to secure.
Plan recurring checks around door travel, hardware wear, latches, seals, and fleet use.
Prepare for replacement when repair is no longer the practical path for the door and opening.
Use the Portland service page for regional contact details, scheduling routes, and local box truck door service context.
Discuss a box truck, semi-trailer roll-up door or fleet maintenance request with Boise.
Use this path for fixed commercial openings, dock areas, operators, and facility door planning.
See how inspection findings, options, quote review, and customer approval fit together.
Share the system, site, location, and observed problem. D&L will confirm whether the request fits the current service area and explain the next step.
