The short answer
Get at least three quotes from DHF-accredited garage door installers, all on the same specification, and insist on an itemised written quote after an on-site survey rather than a phone-only price. Tell each installer the same brief — the door type, whether you want manual or electric operation, the level of insulation, and whether the old door needs removing — so the quotes are comparable. Then line them up item by item and weigh price alongside guarantee, survey quality and reviews. See how to choose a garage door installer for the checks that matter.
Getting quotes is the step where homeowners most often end up comparing apples with pears — one quote includes a better-insulated door or an electric motor, another leaves out removing the old door or making good the opening. This guide explains what to tell installers, what a good quote should contain, and how to compare three quotes fairly. We are an independent information and introduction service: we do not fit garage doors, and we publish this guidance free.

What to tell each installer
To get comparable quotes, give every installer the same brief. The more precise you are, the less room there is for quotes to drift apart on hidden differences. Cover the door type you want, whether the door should be manual or electric, the level of insulation, the size of the opening, and any access issues such as a sloping drive or limited headroom. Ask each to survey the garage rather than quote over the phone, because a measured survey is what makes a quote reliable.
| Tell the installer | Why it matters |
|---|---|
| Door type | Up-and-over, roller, sectional or side-hinged changes price significantly |
| Manual or electric | Automation typically adds £300–£800 and must match across all three |
| Insulation level | Single-skin vs insulated double-skinned door affects price and comfort |
| Opening size | Single or double width, plus any non-standard dimensions |
| Removal & access | Taking away the old door, plus headroom or drive access, affect price |
What a good written quote includes
A quote you can rely on is itemised and in writing, not a single headline figure. It should set out the door type and finish, the operation (manual or electric, and which motor), the insulation specification, the fitting work, removal and disposal of the old door, the guarantee length and terms, and the deposit and payment schedule. If a quote is vague about any of these, ask for it to be spelled out before you compare.
How to compare quotes fairly
With three written quotes on the same brief, line them up item by item. A price gap often comes down to one quote including an insulated door, an electric motor, or removal of the old door that another omitted — adjust for anything missing before judging on price. Sense-check the figures against typical costs in our garage door cost guide, then weigh the things price alone does not capture: the quality of the survey, the clarity of the guarantee, independent reviews and how the installer communicated. The cheapest quote is not automatically the best value, and the most expensive is not automatically the safest. These are general pointers, not advice for your specific job.

Frequently asked questions
How many garage door quotes should I get?
At least three, all on the same specification — same door type, manual or electric operation, insulation level and opening size. This lets you compare fairly and spot a quote that is cheap only because it leaves something out, such as removing the old door.
Should I get a survey or a phone quote?
Insist on an on-site survey. A measured survey is what makes a quote reliable; a phone-only or online estimate can change significantly once an installer sees the opening, the headroom and any access or repair work needed. A proper survey also lets you judge how the installer works.
What should a garage door quote include?
An itemised written quote should list the exact door type, size and finish, manual or electric operation, the insulation specification, the fitting work, removal and disposal of the old door, the guarantee terms, and the deposit and payment schedule. For powered doors it should confirm the work meets the relevant safety standards. Ask for anything vague to be spelled out.
Is the cheapest garage door quote the best?
Not necessarily. A lower price can mean a single-skin door, a manual rather than electric operation, or omitted work such as removing the old door or making good the opening. Compare on a like-for-like specification and weigh the guarantee, survey quality and reviews, not just the headline figure.
