Live demov2026.3 / garage doors

The garage door
price calculator.

Three sections. garage door, optional front door, optional wall cladding. Same shape every garage-door installer in Sydney uses, with your own rates and margins.

/ General

Tick if the door is clad with timber, batten, or composite boards over the panel. Most basic Colorbond panel-lift jobs are NOT clad. Leave unticked.

Auto-resolved from the cladding profile you pick (e.g. Batten 50x25 = 50mm). Shown for reference; the profile width drives the board count.

Leave blank to use your onboarding default.

$

Auto-estimated from mount type + width. Override if your supplier price differs.

$

Roller / sectional double doors are wider and need bigger insulation kits + 2 remotes standard.

Adds the insulation upgrade for this door type. Auto-prices ~$280-$380 single, ~$560-$760 double (lookup by door_type).

Most motors ship with 2. Each extra is added at your remote_unit_cost from onboarding.

Total install hours for the crew. Standard 2.4×2.4 sectional ≈ 3-4 hrs with 2 of you; doubles, premium clad, or wind-locked installs go 6-10. Leave at 4 if you're not sure. You can edit on the quote.

Only shown when your cart-away policy is 'Optional'. Adds the cart-away fee to this quote.
