A cold store dock door is an insulated loading bay door built for chilled or frozen buildings, usually a sectional door with thick insulated panels or a high-speed door with an insulated curtain. It differs from a standard dock door in its thermal breaks, extra seals and, on freezer docks, heating in the frame or seals so that ice cannot lock the door shut or tear the seals.
What should sites in Gorseinon consider?
Any cold store dock survey in Gorseinon is carried out with the store running, so we can see ice, seals and traffic as they really are. Converting an ambient unit in Gorseinon to chilled storage usually means replacing standard dock doors with insulated ones and sealing around the trailers.
Food manufacturers in Gorseinon moving finished product into frozen storage need doors that resist ice and close quickly behind each forklift or trailer movement.
Before anything is ordered, we visit your site in Gorseinon 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 does a cold store door work with the shelter and leveller?
On a cold store dock the door, shelter and leveller should work as one system, with the door opening only once the trailer is sealed against the building and closing before the seal is released.
A typical sequence is:
- The trailer reverses onto the bumpers and is held by a restraint, or the driver's keys are taken.
- The shelter inflates or the seal compresses around the trailer.
- The door opens and the leveller lip is lowered onto the trailer bed.
- Loading takes place inside a sealed link between store and trailer.
- The leveller is stored, the door closes, then the shelter releases.
Interlocks make this sequence automatic, so the door cannot be left open with no trailer present. Insulated leveller platforms and seals around the pit also reduce cold loss through the floor of the bay.
How much does a cold store dock door cost?
A cold store dock door typically costs £4,800 to £9,500 per door, excluding VAT, supply and fit. Chilled docks usually sit lower in that range than freezer docks, because freezer doors need more insulation and frame heating.
Price is mainly driven by:
- Operating temperature: chilled, frozen, or a door between two temperature zones.
- Door type: insulated sectional, insulated high-speed, or both at one opening.
- Heating: heated frames, heated bottom seals or threshold heating to stop ice forming.
- Panel thickness and thermal breaks: thicker panels and better breaks reduce condensation and heat gain.
- Controls: faster operators, interlocks with shelters and levellers, and automatic closing.
- Working conditions: installing in a live cold store often means out-of-hours work and temporary screening.
We price each door after a free site survey, and the written quote fixes the cost.
The same published guide range applies across Wales; access, out-of-hours working and site conditions are confirmed at the free survey.
What do we check at the survey?
- Traffic routes for vehicles and separation of pedestrians
- Yard gradient and the slope of the approach to the dock
- Power supply at each bay, including three-phase availability
- How drivers are prevented from pulling away too early
- How often each door cycles during a typical shift
- Dock height and the mix of trailers you load
Options to discuss
Dock interlocks
Controls that link the door to the shelter, leveller and restraint so the door only opens when a trailer is docked and sealed against the building.
Insulated high-speed door
A fast door with an insulated curtain for busy openings between temperature zones, where cutting open time matters more than maximum insulation.
What do the rules in Wales mean for the work?
Wales has its own energy requirements for buildings, set out in Approved Document L for Wales. For new or replacement loading bay doors in Gorseinon, we confirm the figure that applies to your project rather than assuming the English one, and we check what applies at survey before a door is specified.
Questions about cold store dock doors in Gorseinon
Can you work outside our normal operating hours in Gorseinon?
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.
Can you work alongside our main contractor on a new build in Gorseinon?
Yes. For new warehouses and fit-outs, we can supply and install the dock package as part of a wider project, working to the main contractor's programme, site rules and permits. We will need drawings, dock levels and the programme, and we coordinate pit details, power supplies and door openings with the relevant trades before installation begins.
How long does installation take at a site in Gorseinon?
It depends on the equipment, the number of bays, the condition of the dock and whether any building or electrical work is needed. We agree a programme with you after the survey, setting out which bays are out of use and when. Larger jobs are usually phased so that part of the dock stays open, and out-of-hours working can be arranged.
Do cold store doors need more frequent servicing?
Yes, cold store doors generally benefit from more frequent servicing than ambient dock doors. Low temperatures stiffen seals, stress springs and cables, and hide early ice build-up. Checking heaters, seals and operator settings before winter is particularly worthwhile. Servicing visits are chargeable and agreed in advance.
Do heated door frames use a lot of power?
Frame and seal heaters are low-power elements designed to keep surfaces just above freezing rather than to heat the dock. Many can be controlled by a thermostat so they only run when needed. We set out the supply required in the written quote so it can be planned before installation.
