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.
What should sites in Market Harborough consider?
Older seals at docks in Market Harborough that have been left with split covers can soak up rain, becoming heavy and losing their shape over winter. Weather-exposed bays in Market Harborough gain the most from a well-fitted seal, since wind and rain otherwise find every gap around the trailer.
Heated packing halls next to a dock in Market Harborough lose less warmth during loading when the gap around each trailer is closed by compressed foam.
Here is what happens after you contact us about a site in Market Harborough. We arrange a free survey, measure up and send a fixed written quote. If you go ahead, we manage the whole job, including ordering, delivery and coordination with your site team. Specialist installation engineers working under our management do the fitting, at times built around your loading schedule, with out-of-hours work by arrangement. Testing and handover documents close the job.
When is a dock seal a better choice than a shelter?
A dock seal is a better choice than a shelter when the trailers using a bay are consistent in size, the dock height suits them, and the tightest practical seal matters. Mixed fleets are usually better served by a shelter.
- Consistent fleets: dedicated vehicles or regular hauliers using the same trailer type.
- Temperature control: chilled or heated buildings where gaps around the trailer are costly.
- Security and hygiene: fewer gaps for pests, dust and unauthorised access during loading.
- Budget: seals cost less than inflatable shelters for a close fit.
The trade-offs are that seals can leave gaps at trailer door hinges, side pads can intrude into the trailer opening if poorly sized, and the covers wear from rubbing. If your trailers vary, compare our retractable dock shelters before deciding, as they leave the full opening clear.
Why does the gap between the seal and the bumpers matter?
The distance between the face of the seal and the face of the bumpers decides how far the trailer compresses the foam, and getting it right is the difference between a good seal and pads that are crushed or leave gaps.
- Too little projection: the trailer meets the bumpers before it presses the foam enough, leaving gaps at the head and sides.
- Too much projection: the foam is over-compressed, which crushes the pads, strains the fixings and can push the trailer forward as the foam recovers.
- Worn bumpers: let trailers travel further than designed, over-compressing the seal every time.
Correct projection depends on the foam depth and your trailers, so we set it at installation and it should be checked at each service. Keeping dock bumpers in good condition protects both the seal and the leveller from repeated impact.

Survey checklist for your dock
- Drainage on recessed or sloping dock approaches
- Control positions, isolators and any existing interlocks
- How often each door cycles during a typical shift
- Wall and steel structure for door, shelter and bumper fixings
- Gaps around trailers where heated or chilled air escapes
- How drivers are prevented from pulling away too early
Options to discuss
Tapered side pads
Side pads tapered in section so they guide the trailer in and intrude less into the trailer opening, which extends pad and cover life.
Seal with curtain head
Foam side pads combined with a flexible top curtain that adjusts to trailers of different heights, a halfway point between a seal and a shelter.
Regulations and approvals in England
Workplace safety in England is regulated by HSE. For a loading bay in Market Harborough, 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 about dock seals in Market Harborough
How do you price dock seals for a site in Market Harborough?
Guide budgets for supply and fit are £1,100 to £2,600 per set, excluding VAT. The figure moves with size, insulation, the operator, electrics, access, any pit or groundworks and out-of-hours working. Where levellers are involved, the guide assumes an existing, sound pit. After the free survey you receive a fixed written quote, and that is the price for the agreed scope.
Is the site survey in Market Harborough 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.
Can you work outside our normal operating hours in Market Harborough?
Yes, by arrangement. Evening, night and weekend working can be planned so the installation causes as little disruption as possible to your loading schedule. Out-of-hours work can affect the price, so mention it at the survey and we will include it in the written quote. The agreed times are confirmed in the programme before the job starts.
Are dock seals suitable for cold stores?
Yes, for cold stores with consistent trailers a dock seal gives a tight fit at a lower cost than an inflatable shelter. The pads must be kept in good condition, because water in the foam can freeze and stiffen it. Mixed fleets at cold stores are often better served by inflatable shelters.
How can I tell if seal projection is wrong?
Look at the pads with a trailer docked. Daylight around the head or sides suggests too little compression, while pads squashed flat or bulging around the trailer suggest too much. Worn bumpers are a common cause, and both can be checked at a planned service.
