Window Replacement Calculator
Built for dealers that sell and install replacement windows and entry doors and quote after an in-home measure. The homeowner fills a card for every kind of window: style (double-hung, single-hung, slider, casement, awning, picture, bay or bow), a common size, a typed size in inches or 'measure for me', quantity, which floor, grids, obscure and tempered glass. One frame material, glass package, ENERGY STAR and exterior color apply to the whole house. Entry doors get their own cards: style, steel, fiberglass or wood, factory finish, sidelites and transom, hardware, smart lock, storm door, size and swing. Then insert or full-frame installation, haul-away, trim and capping, or supply only. Prices are per window by style and material with size tiers by united inches, per door and per opening for the install; the estimate is shown as a range, a promotion and a minimum job apply, and the visitor downloads a PDF estimate.

Frequently Asked Questions
How can the form give a price when the windows have not been measured yet?
Every window card offers common sizes, a typed size in inches or 'measure for me'. For a window left to the measure the estimate assumes a typical size for its style, and the result is shown as a range of plus or minus 12% that covers what a measure usually finds. A firm quote follows the measure.
How are the window prices built?
Each style has a base price for a white vinyl window in the smallest size tier. Larger windows move into size tiers by united inches (width plus height) with a percentage surcharge, fiberglass, wood-clad and aluminum frames add a percentage, triple-pane glass and ENERGY STAR add a percentage, and grids, obscure glass, tempered glass and a tan or black exterior are per-window options. Every rate is a constant at the top of the code.
Can I quote entry doors too?
Yes. The visitor chooses windows, doors or both. Each door has a style, material, factory finish, sidelites, transom, hardware, smart lock, storm door, size and swing, and the installation is priced per door. Remove the door part if you only sell windows.
What installation options does the calculator cover?
Measure and install or supply only. For replacement jobs the visitor picks insert (pocket) or full-frame installation per opening, haul-away of the old windows, interior trim with exterior capping, and marks which windows are upstairs for the ladder surcharge. A minimum job amount applies last.
What does the homeowner receive after submitting?
A PDF estimate with the windows and doors tables, the installation details, the estimated cost range, next steps and terms. You get the lead with the contact details, the best time to call and the whole configuration, so the consultant has everything before the visit.
