An accurate automatic door quotation depends on four things: where the door will be installed, how it will be used, the size and condition of the opening, and any additional requirements such as access control or emergency operation. The clearer this information is at the start, the closer the quote will be to the final cost, and the fewer revisions you will need later.
You do not need to know the door type or technical specification in advance. Recommending the right system is the supplier’s job. Good input simply saves time and makes competing quotes easier to compare.
Why Quotes for the Same Door Can Differ
It is common to receive quotes that look very different for what seems like the same request. Usually each supplier has made different assumptions about the drive system, usage, accessories, preparation work and installation scope. Giving every supplier the same clear brief is the most reliable way to get comparable offers.
Key Information and Why It Matters
| Information | Why it matters |
|---|---|
| Facility type and door location | Defines traffic type, appearance and security needs (main entrance, warehouse, car park). |
| Usage type and intensity | Drives the choice of operator and component durability. |
| Approximate opening size | The starting point for selecting door type and size. |
| Space around the opening | Some systems need side room, others need headroom. |
| Power near the opening | Affects electrical work required before installation. |
| Control and operation | Sensors, push buttons, cards, integration with other systems. |
| City and timeline | Affects logistics and the sequencing of supply and installation. |
Details That Improve Accuracy
How the door will be used
Describe the traffic: pedestrians only, forklifts and trucks, or cars? Will it run all day or at set times? Does it separate areas with different temperature or hygiene conditions? The answers guide the choice between options such as sliding doors, sectional doors and high-speed doors.
The opening
Send approximate width and height if you have them, and say whether the opening already exists or is still at design stage. Mention any old door that needs removal. If dimensions are not confirmed, final figures are taken during the site survey.
Photos and drawings
Clear photos of the opening from both sides, showing the ceiling, side walls and floor, help a great deal at the initial stage. Attach architectural or structural drawings if available.
Additional requirements
Note any special needs: card or PIN access, fire alarm interface, manual operation during power loss, or insulation. It is also worth confirming any regulatory requirements for your project with your consultant or the relevant authority.
Quick Checklist Before You Send a Request
- Location: city and project or facility name.
- Quantity: number of doors, and type of each opening if they differ.
- Usage: people, vehicles, goods, or a mix.
- Dimensions: approximate or confirmed.
- Photos or drawings: if available.
- Power: available near the opening or needs to be run.
- Control: how the door should open, and any system integration.
- Timeline: when the site is expected to be ready.
- Contact: the responsible person on the owner or contractor side.
For projects with many openings, a simple door schedule helps: give each opening a reference, its location on the drawing, approximate size, usage and any special requirements. It makes the quote easier to review line by line and becomes a shared reference through supply, installation and handover.
When Is a Site Survey Necessary?
Initial information is often enough for a budget quote. A site survey becomes important when the opening is irregular, space around it is tight, an existing door needs replacing, or the project includes several doors of different types. The survey confirms dimensions, structural condition and power availability so the specification can be fixed before final approval.

Common Mistakes When Requesting a Quote
- Asking for “an automatic door” and nothing more: the quote ends up built on assumptions that may not fit.
- Unclear dimensions: say whether figures come from drawings or site, and whether they are structural or finished sizes.
- Adding requirements late: access control or alarm interfaces added after approval change cost and timeline.
- Undefined scope: is removal of the old door, electrical work or making good included?
- Comparing on price alone: check that every quote covers the same scope and components.
What a Good Quote Should Tell You
A quote should be easy to review. Look for the proposed door type and main components, supply and installation scope, work expected from the owner or contractor, the assumptions used, an estimated programme, and after-installation support. If anything is unclear, ask before you approve, not after.
Next Step
Gather whatever you have from the list above, even if some details are still open, and send it through the Request a Quote page. If the opening or requirements need a closer look, you can request a site survey and technical assessment, and we will help define the right solution for your project.
