Dock shelter and seal repair covers restoring the weather seal around a docked trailer. Typical work includes replacing torn side and head curtains, worn foam seal pads and their covers, top pads and guide strips, repairing or replacing airbags and blowers on inflatable shelters, and straightening or replacing bent shelter frames, so the bay closes the gap between building and trailer again.
Why do sites in Lisburn choose this?
Curtains tearing at the corners at docks in Lisburn can be a sign that taller or wider trailers are arriving than the shelter was sized for. If tenants change at a unit in Lisburn, checking the shelters and seals is sensible, because a new fleet may not suit the old curtain sizes.
Multi-bay sites near Lisburn often find several shelters in similar condition, so measuring and replacing curtains across the dock in one programme can reduce costs.
For dock shelter and seal repairs at sites in Lisburn, you will always know the cost before anyone sets off. The visit is chargeable and its price is agreed in writing. Clear photos of the problem help the engineer arrive prepared. Where the visit reveals more work, we stop, explain and quote before going further, and a written report follows every attendance so you have a record of the condition of each item.
Why is my dock shelter or seal letting in draughts?
A dock shelter or seal lets in draughts when the material that should press against the trailer is torn, worn, too short or no longer in the right place. Daylight around a docked trailer is the clearest sign.
- Torn or shrunk curtains: side curtains no longer overlap the trailer sides.
- Short head curtain: taller trailers than the shelter was sized for leave a gap across the top.
- Flattened seal pads: foam that has lost its spring no longer closes the gap.
- Worn pad covers: exposed foam soaks up water and breaks down faster.
- Bent frame: a retractable shelter frame that no longer returns square.
- Airbag or blower fault: inflatable shelters that inflate slowly or lose pressure.
- Trailer position: off-centre parking or worn bumpers that let trailers crush one side.
On chilled docks, gaps also show up as condensation, ice on the dock floor or frost around the door.
Do dock shelters and seals fall under PUWER?
Yes. Dock shelters and seals are work equipment under the Provision and Use of Work Equipment Regulations 1998 (PUWER), so they must be suitable, maintained in a safe condition and inspected where deterioration could lead to danger. In Northern Ireland the equivalent is PUWER (Northern Ireland) 1999.
Shelter and seal damage is often treated as a comfort or energy issue, but some faults are safety issues too:
- loose head curtains, top pads or fixings that could fall;
- bent or broken frame arms with sharp edges at head height;
- wet or icy dock floors caused by gaps around the trailer;
- electrical faults on inflatable shelter blowers.
The regulator is HSE in Great Britain and HSENI in Northern Ireland. Including shelters and seals in planned maintenance, and recording what is found, shows they are being kept in a safe condition. Problems found during servicing are quoted as repairs before any work is done.
The visit price is agreed before anyone attends. Parts and any extra work are quoted before they are fitted.

Options to discuss
Frame repairs
Straightening or replacing bent arms, springs and frames on retractable shelters damaged by off-centre trailers, so the shelter returns square after each docking.
Curtain replacement
New side and head curtains for retractable shelters, made to measure in hard-wearing coated fabric, with slits and overlaps set to suit the trailers you receive.
Regulations and approvals in Northern Ireland
Northern Ireland has its own system. Structural alterations at a site in Lisburn, such as a new opening or dock pit, may need building control approval from the council, and external structures such as loading houses or canopies can need planning permission through the council planning service. We check what applies before any work starts.
Questions about dock shelter and seal repairs in Lisburn
Can repairs be carried out outside our working hours?
Yes, by arrangement. Evening, night or weekend visits can be booked so that repairs and servicing at your Lisburn site cause less disruption to loading. Out-of-hours attendance usually affects the price, so we include it when we agree the visit charge in writing. Tell us your shift pattern and the times when the dock is quietest.
How often should equipment at our Lisburn site be serviced?
It depends on how hard the equipment works and on the manufacturer's recommendations. A multi-shift dock with frequent trailer movements needs more attention than a door that opens a few times a day. We suggest a schedule after looking at the equipment and how it is used, and we can line visits up with your insurance inspections where that helps.
What happens if the engineer finds the equipment unsafe?
If equipment is found to be unsafe, the engineer will tell you straight away and recommend that it is isolated and taken out of use until it is repaired. That is recorded in the written report. We then quote the repair so you can decide how to proceed. Keeping an unsafe door or leveller in service puts people at risk, so we will always raise it.
Do you repair inflatable dock shelters?
Yes. We repair and replace torn airbags, failed blower motors, controls and fixings on inflatable shelters. Where the shelter is interlocked with the dock controls so it only inflates with a trailer present, that link is checked as part of the repair.
Can worn dock seal covers be replaced without new foam?
Often, yes. If the foam inside a seal pad still springs back, a new cover can be fitted over it. If the foam has stayed compressed or soaked up water, the pad is usually replaced complete. Photos of the pads, front and side, help us judge which applies.
