Quick Window Estimate (USA)

Preview pricing only. Full calculator factors in NFRC U-Factor, SHGC rating, grille patterns, interior/exterior colors, and labor costs for your state.

Built for the American Window Market

Price windows the way US professionals actually work — imperial units, NFRC ratings, and local labor.

1

NFRC & Energy Star Logic

Enter U-Factor, SHGC, and VT values. The app flags products that meet Energy Star v7.0 for your climate zone (North, North-Central, South-Central, or South) — critical for federal tax credits and rebates.

2

US Profile & Brand Library

Pre-loaded cost data for vinyl, fiberglass, aluminum-clad wood, and pure aluminum windows from Andersen, Pella, Jeld-Wen, Marvin, Milgard, and Simonton. Adjust to match your dealer pricing.

3

State-Level Labor Rates

Install labor varies wildly — $75/window in Texas, $250/window in New York. Set labor by state or zip code and the estimator applies it automatically for every new quote.

AIA-Compliant Specs for Architects

Export product specifications in a format architects can drop into a 08 52 00 or 08 54 00 specification section. Bridges the gap between residential estimating and commercial work.

The US Residential Window Market

The US residential window market moves about $30 billion annually, with vinyl dominating replacement work, fiberglass gaining share in premium new construction, and aluminum-clad wood holding the custom-home segment. Demand is heavily seasonal — Q2 and Q3 carry most of the installation volume.

Doorwin is built for the way US window professionals actually operate: mixed metric/imperial specs, wide variation in state labor costs, and constant reference to NFRC and Energy Star values. Whether you're quoting a vinyl tilt-wash in Ohio or an aluminum-clad casement in Colorado, the math is the same.

Frequently Asked Questions (USA)

Does it work in inches and feet?
Yes. The default unit for US users is inches, with automatic conversion to feet-inches display (e.g., 48" = 4'-0"). You can switch to millimeters or centimeters if you're working with imported European systems.
How does it handle Energy Star ratings?
Each window spec includes fields for U-Factor, SHGC, and VT. When you enter these values, Doorwin checks them against the current Energy Star v7.0 criteria for each US climate zone and flags whether the product qualifies for federal tax credits (currently up to $600 per year for qualifying windows).
Can I match my dealer's pricing from Pella, Andersen, etc.?
Yes. Upload a CSV price list from any US window supplier — Doorwin imports model numbers, list pricing, and dealer margins, then builds quotes at your net cost plus your markup. No retyping every SKU.
Is it useful for commercial window projects?
Partially. Residential and light-commercial work is fully supported. For heavy commercial (curtain wall, storefront with AAMA ratings), Doorwin handles the design and takeoff but you'll still need AAMA-specific engineering for the structural submittal.
