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.
Is this right for your site in Durham?
During warm, humid spells, any cold store dock in Durham is most exposed to condensation and ice, which is why heated frames and good shelters are worth considering. Converting an ambient unit in Durham to chilled storage usually means replacing standard dock doors with insulated ones and sealing around the trailers.
When an older cold store in Durham has a door that has been repaired many times, a planned replacement can be timed for a quieter trading period.
For cold store dock doors in Durham, we begin with a free site survey and a fixed written quote, so you know the scope and cost before committing. We take responsibility for managing the job, and specialist installation engineers carry it out under our supervision. Bays are taken out of use in a planned sequence so the rest of the dock keeps working, and evening or weekend work can be arranged. Each item is tested at handover and the documentation is left with you.
How can a cold store door be replaced without losing temperature?
A cold store door can be replaced with very little temperature loss if the work is planned around the store, with the opening screened and the fitting done in one continuous visit.
On a live cold store we usually:
- schedule the work for the quietest period, often overnight or at a weekend,
- fit a temporary insulated screen or strip curtain while the opening is exposed,
- remove ice from the old frame and threshold before fixing the new door,
- pre-assemble as much as possible so the opening is exposed for the shortest time.
From your side we need product moved back from the opening, any site permits for working in cold areas, and power for the operator and frame heaters. Heated frames typically need their own supply, which we set out in the quote. Our cold store loading bays guide covers planning the work in more depth.
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.

- Gaps around trailers where heated or chilled air escapes
Options to discuss
Insulated sectional cold store door
Thick insulated panels with thermal breaks and full perimeter seals, the usual choice for chilled and frozen external dock openings that also need to be secure overnight.
Heated frames and seals
Low-power heating in the side frames, bottom seal or threshold that keeps contact surfaces above freezing so the door does not ice up or tear its seals.
Planning, building control and safety law in England
Sites in Durham fall under the rules for England. Structural changes such as forming a new opening or a dock leveller pit may need Building Regulations approval, and external structures such as loading houses, canopies or new dock approaches can need planning permission from the local planning authority. We check what applies at survey and build any approvals into the plan.
Questions about cold store dock doors in Durham
Can you work alongside our main contractor on a new build in Durham?
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.
Is VAT included in your guide prices for cold store dock doors?
No. Our customers are businesses, so guide prices exclude VAT, which is added at the standard rate. The same guide range applies in County Durham as everywhere else: for cold store dock doors, it is £4,800 to £9,500 per door, excluding VAT. It covers supply and fit for a typical installation. Your fixed written quote after the free survey shows the net price, the VAT and exactly what is included.
What warranty comes with new loading bay equipment?
New equipment comes with the manufacturer's warranty, which varies by product. Our workmanship terms are set out in writing in the quote for your Durham site, so you can see what is covered before you commit. Check the warranty terms for any servicing conditions, and we can quote for planned maintenance once the installation is complete.
What happens to a cold store door in a power cut?
In a power cut the door stops where it is and the frame heating switches off, so it must be possible to operate the door by hand. Powered dock doors normally have a hand chain, crank or release for this. We show your team how to use it at handover so the store can be closed up quickly.
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.
