Windows & doors bid estimation — AI calculates quantities for you
Windows and doors bid estimation starts with counting quantities and sizes. Massoi reads blueprints and identifies windows, doors, and their types automatically.
Challenges in windows & doors bid estimation
Dozens of types and sizes
A mid-rise apartment can have 10-20 different window types and 5-10 door types. Each size, material, U-factor, and piece of hardware must be recorded separately.
Fire, energy, and sound ratings
Fire-rated doors (20/45/90 minute), ENERGY STAR U-factors, STC 35-50 sound ratings, safety glazing in hazardous locations — each requirement significantly changes price and lead time.
Hardware and accessories
Levers, locksets, hinges, door closers, weatherstripping, flashing — accessories can be 20-30% of installation cost and are easily overlooked during takeoff.

Frequently asked questions about windows & doors bid estimation
How are window and door quantities calculated for a bid?
Quantities are calculated from floor plans and elevation drawings. For each opening, the type, rough opening, material, and special requirements (fire rating, STC, U-factor, safety glazing) are recorded. AI identifies window marks and door types automatically and counts quantities by type.
How much does a window replacement cost in 2026?
A single vinyl window typically costs $500-900 installed (window + installation + flashing + sealing). An ENERGY STAR window (U-factor 0.25 or better) runs 20-35% more than a standard window. Replacing all windows in a single-family home typically costs $10,000-25,000. A mid-rise apartment window contract is typically $150,000-400,000.
What does the window U-factor mean in a bid?
The window U-factor indicates thermal insulation performance (Btu/hr-sqft-F). IECC and ENERGY STAR requirements typically call for 0.27-0.32 in new construction, depending on climate zone. A better U-factor (0.22 vs. 0.30) means a $200-400 surcharge per unit, but lower energy consumption. The U-factor must be specified in the bid as it affects both window and installation pricing.
