The sliding patio door price is a sliding glass patio door, supplied and installed, with the old door taken out. The interior door price is labor only: taking out the old door, frame and trim and hanging a prehung door you supply.
Can I price several doors together?

How are these prices set?
Each item's price is set against the lowest 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?
French patio doors, storm or screen doors, and an interior door supplied and installed are not priced. They are quoted after a walkthrough. Garage doors and openers have their own calculator at /calculator/garage-doors.
