Using this calculator
What does each price include?
The single-car price is a basic steel door, installed, with the old door taken out. The double-car price is an insulated steel door, installed, with the old door taken out. The opener price is a new garage door opener, supplied and installed.
Can I price doors and openers together?
Yes. Switch on each item and set the quantity. An insulated double-car door with a new opener comes to about $1,710, and two single-car doors with two openers come to about $2,090.
Is there a job minimum?
No. Each item is priced on its own, so a new opener alone comes to about $285.
How are these prices set?
Each item's price is set against the lowest installed price that registered Seattle-area contractors publish on their own websites for the same scope, dated 2025 or 2026, at about 95% of it. Lead-generation and pricing-template sites never set a price, and neither do Kolmo's own quotes. The full method is at /how-estimates-work.
What doesn't the calculator price yet?
This calculator prices garage doors and openers. Entry, interior, patio and storm doors are not in it yet; they are quoted after a walkthrough.
