Want the real quote, done for you?
This is a rough number. Vorkeon builds the full window installation quote from one sentence:
- Materials with waste, and crew time from your own pace
- Current prices from building-supply stores near the job
- A clean PDF with your logo that the customer signs on their phone
- Then the invoice, reminders and your crew's hours, in one app
What drives the price of a window installation job
- Window size and type. Sliders, casements, bays and large picture windows differ in cost.
- Insert vs full-frame. Full-frame replacement means more demolition, framing and trim.
- Glass options. Double or triple pane, low-E coatings and tempered glass.
- Floor level. Upper floor windows may need scaffolding or extra crew.
- Wall type. Brick, stucco and siding each need different finishing.
- Interior trim. New casing and painting, or reuse of the old trim.
A worked example
Example only, made-up numbers, not a price guide. 8 windows at 500 material and 250 labor each: 8 × 750 = 6,000. Add 400 for exterior capping and 300 for disposal, for 6,700. With 20% markup the quote is 8,040 before sales tax. Window prices depend on brand, size and region, so check your supplier.
What to put in your window installation quote
- Each window with size, type, location and opening style
- Brand, frame material, glass and color
- Insert or full-frame install
- Interior trim, exterior capping and sealing
- Old window removal and disposal
- Lead time from the supplier and the warranty on product and labor
Prices vary by region and change over time: use your own supplier prices and labor rates. Updated October 30, 2026.
Window installation quoting questions
Why do window quotes list each window separately?
Sizes, types and locations differ, so a per-window list avoids mistakes when ordering. It also lets the customer drop a window or two if the total is too high.
Should I take a deposit for custom windows?
Many installers do, because custom windows are made to size and cannot be returned. Say the deposit amount and when it is due in the quote.
How do I price a window installation job?
Multiply the number of windows by your material and labor cost per window, then add your markup to cover overhead and profit. Add tax on top when you send the quote.
What markup should I use?
Use the markup that covers your overhead (vehicle, insurance, tools, office) and leaves the profit you want. Many contractors land between 15% and 35%, but your own costs decide it.
