A dock seal is a set of fabric-covered foam pads fixed to the building around a loading bay door, usually a head pad and two side pads. When a trailer reverses in, its rear end presses into the foam, which compresses to close the gaps around the trailer body. Seals give a very tight fit but work best when the trailers using the bay are a consistent size.
How does this suit sites in Dorset?
Before recommending seals for a bay in Dorset, we check how consistent your trailers are, because mixed fleets are usually better served by a shelter. Heated packing halls next to a dock in Dorset lose less warmth during loading when the gap around each trailer is closed by compressed foam.
Hygiene-sensitive sites in Dorset, such as food processors, can use dock seals to reduce the gaps through which dust and pests might enter during loading.
Before anything is ordered, we visit your site in Dorset for a free survey and then send a written quote with a fixed price. From that point we manage the installation, coordinating delivery, access and any other trades. Fitting is done by specialist installation engineers engaged and managed by us, at times that suit your operation, including out of hours where agreed. You get a tested installation, a demonstration for your team and the manufacturer documentation.
How are dock seals fitted to a loading bay?
Dock seals are fixed to the outside wall around the dock door, normally on brackets or a frame that sets their projection, and a set usually takes a few hours to fit. No power supply is needed.
- The wall is checked for sound fixing points, with a frame or spreader plates added on cladding.
- The head pad and side pads are positioned to suit your trailer width and height.
- Projection is set relative to the bumpers, so trailers compress the foam by the right amount.
- Bumpers are checked and, if worn, replaced at the same time.
- A trailer is docked to confirm an even seal along the head and sides.
From you we need the bay taken out of use, a clear area in the yard for powered access equipment and, ideally, one of your usual trailers available at the end of the job so the fit can be checked under real conditions.
How much do dock seals cost?
A set of dock seals typically costs £1,100 to £2,600 per set, excluding VAT, supply and fit. A set is normally a head pad and two side pads for one bay.
The price depends on:
- Pad size and depth: larger openings and deeper foam cost more.
- Head arrangement: a fixed head pad, or a curtain head for varied trailer heights.
- Cover fabric: heavier coated fabric and replaceable wear pleats last longer.
- Pad shape: tapered side pads that guide the trailer and intrude less into the opening.
- Mounting: fixing direct to masonry, to a steel frame, or to brackets that set the projection.
- Site work: removing old seals, adjusting bumpers and powered access equipment.
Where the foam is still sound, new covers can cost less than new pads, and we will say if that is an option. After a free site survey you receive a fixed written price for the work described.

What do the rules in England mean for the work?
Workplace safety in England is regulated by HSE. For a loading bay in Dorset, that means doors meeting regulation 18 of the Workplace (Health, Safety and Welfare) Regulations 1992, equipment maintained under PUWER and suitable safeguards against vehicles driving away too early. We check what applies at survey and design the bay accordingly.
Questions
Is the site survey in Dorset free?
Yes. For new installations, replacements, upgrades, conversions and complete bays, the site survey and written quote are free and come with no obligation. The survey lets us measure the openings, check the dock and structure, and understand how the bay is used, so the quote reflects your site. Repair and servicing visits are different: they are chargeable, with the price agreed before anyone attends.
Do you remove and dispose of the old equipment?
Yes, where it is part of the scope. When we replace doors, levellers, shelters or seals at a site in Dorset, removal and disposal of the old equipment can be included and is itemised in the quote, so it is clear what is covered. If anything should be kept, such as a frame or motor that is still serviceable, we agree that at survey.
Can just the covers be replaced?
Yes, if the foam is still resilient and dry, new covers can often be fitted over the existing foam, which usually costs less than new pads. Waterlogged or permanently crushed foam should be replaced. Cover replacement is handled as a repair, with the visit price agreed beforehand.
Do dock seals block access to the trailer?
They can if they are poorly sized. Side pads that sit inside the line of the trailer body intrude into the opening and get in the way of pallets and forklifts. Correctly sized and tapered pads compress against the rear corners and leave the opening clear.
