What a Fair Garage Door Quote Contains — and What to Ask Before You Sign

Measuring the headroom above a garage opening before specifying a replacement door

Some Perth garage door companies publish price ranges and calculators. We deliberately do not, and it is worth explaining why before the rest of this is useful to you.

A figure on a website is either so wide as to be meaningless, or it is a number that changes the moment somebody actually looks at your door. Neither helps you. What does help you is knowing what a complete quote covers, so that when you have two or three in front of you, you can see which one has left something out — because the cheap one usually has, and the thing it left out is usually the thing that fails.

A quote given over the phone is not a quote

For a repair on a known fault, a phone estimate can be reasonable. For a door replacement it is not, and here is the specific reason: the variables that determine the job are all things nobody can see from a phone.

The exact opening width and height, which is rarely a catalogue size
**Headroom** above the opening — this alone rules door types in or out
Side room and backroom
Whether the opening is square, and by how much it is not
The condition of the jamb the door will be mounted to
The finished weight of the door being proposed

A company quoting a replacement without measuring is quoting a hypothetical door on a hypothetical opening. The number will change.

What a complete quote itemises

The door itself

Type, material, finish and colour, specified rather than described
The actual size being manufactured, not a nominal one
The **lead time**, honestly — custom doors are made to order and that time is the manufacturer's, not the installer's
Warranty on the door, with its actual terms rather than a headline number

The mechanical package — where thin quotes go thin

**Springs sized to the finished door's measured weight.** Ask explicitly. A quote that says "springs" without reference to weight is a chart selection.
**A motor rated for that weight and for the duty cycle.** A heavy custom door on a standard package motor is the most common mechanical failure on architectural installations in Perth.
Tracks, guides, rollers, hinges, cables and drums
Bottom seal and weather strips
Battery backup, if your area needs it — worth asking about above the scarp and in the outer metro

The work

Removal of the old door **and its disposal** — check this is included rather than a line you discover later
Frame assessment, and repair or packing where required
Full set-up: travel limits, force limits, auto-reverse test, remotes paired, manual release demonstrated
Making good, and taking the packaging away
Workmanship warranty, separately from the product warranty

The questions that expose a thin quote

You do not need to be technical. These six are enough:

**"What will the finished door weigh, and what spring set have you specified against it?"** The single most revealing question you can ask.
**"Is the motor rated for that weight?"**
**"Is removing and disposing of the old door included?"**
**"Does my garage have a power point, or will this need an electrician?"** In WA, plugging a motor into an existing power point is not electrical installation work; adding a point or hard-wiring is, and needs a licensed electrical contractor. An operator who is straight about this is straight about other things. We have written about that in who is allowed to work on your garage door in WA.
**"What is the realistic lead time?"** — and note whether the answer changes when you sound impatient.
**"Who services this in three years?"** Custom doors are frequently supplied by manufacturers who install and then move on.

Two things that should make you slow down

**A quote well below the others.** Occasionally that is genuine efficiency. More often something has been left out — usually the spring specification, the old door removal, or the motor rating — and it reappears later as a variation or as an early failure.

**Pressure to decide today.** A door is a made-to-order product with a lead time. There is no version of this where an hour changes the price, and anyone implying otherwise is telling you something about how they work.

What we do instead of a price list

We measure, we tell you what will actually fit, and we give you a free written diagnostic estimate before anything is touched — including on emergency call-outs, where you hear the number before we open the toolbox rather than after.

Where there is a genuine choice between repairing and replacing, we quote both and say which we would do. And where a door is not worth repairing, we say that too, even though the repair would have been the easier sale. If you are at the quoting stage, a free measure and estimate is the sensible starting point.

Frequently asked questions

Why won't you give me a price over the phone?

For a repair on a known fault we can often give you a useful estimate. For a replacement we will not, because the variables that determine the job — the exact opening, the headroom, whether it is square, the state of the jamb, the finished weight of the door — are all things nobody can see from a phone. A number given without those is a hypothetical that will change, and we would rather measure than revise.

What is the single best question to ask a garage door quoter?

"What will the finished door weigh, and what spring set have you specified against it?" It is the most revealing question in the category. Springs must be sized to the door's actual measured weight; a chart selection leaves you either under-sprung, which burns out motors, or over-sprung, which is unsafe. A quote that cannot answer it is not a complete quote.

Should I be worried by a quote that is much cheaper than the others?

Worth slowing down over. Occasionally it is genuine efficiency. More often something is missing — most commonly the spring specification, the removal and disposal of the old door, or a motor rated for the actual weight — and it returns later as a variation or as an early failure. Ask the six questions in this article of every quote and see which answers change.

Is removal of the old door usually included?

It should be, and with us it is. Check explicitly, because it is a common omission and an awkward one to discover on installation day — you do not want to be left with an old curtain rolled up against the side of the house waiting for a verge collection. Ours leaves with the technician and goes to metal recycling.
