Window Project Model

Build the opening inventory

Client-side only

1. Window groups

Window group 1

Group 1

Group label (optional)

Exact quantity

Window style

Frame material

Glass package

Width (optional)

Supply width and height together.

Height (optional)

Inventory only; no size multiplier.

Installation and opening scope

Installation method

Existing opening / frame

Opening change

Access

Pricing pathway

Optional U-factor / SHGC performance screen

U-factor

Enter the actual complete product/configuration rating.

SHGC

Enter both ratings for a complete screen.

2. Home and performance context

These answers surface benchmark, lead-safe, and performance context without applying a price multiplier.

Home condition

Home era / lead-safe planning

ENERGY STAR climate zone

Use the official finder linked in the result; no exact location is collected.

All processing stays in this browser. Nothing is uploaded, persisted, or sent to an API.

Source-backed opening planning

How the window calculator works

Each group uses exactly one base-cost pathway: a Modernize installed-style range, your installed price, or your product-only price. Generic Angi labor is added only for the bounded product-only retrofit pathway shown in the evidence ledger.

Dimensions support the opening takeoff only. Frame and glass survey averages, Angi count rows, method references, home condition, access, lead-safe planning, and performance screening never act as hidden multipliers.

Review all window replacement source context

Carry the inventory into comparable quotes

The result identifies unpriced frame condition, access, opening changes, installation method, restoration, and lead-safe planning rather than treating those unknowns as $0.
