Every opening should be identified
Room, quantity, style, approximate size, operation, color, grids, glass, and specialty requirements should be listed.
Installation method must be clear
Ask whether the contractor is using insert/retrofit or full-frame replacement and what is removed in each case.
Water and air sealing should be described
Flashing, sealants, insulation, sill treatment, exterior capping, and trim details can determine long-term performance.
Repairs need a pricing rule
Rotten wood or damaged framing may not be visible before removal. Ask how repairs are documented and approved.
Bring this checklist to the estimate
- Manufacturer/product
- Glass package
- Install method
- Interior trim
- Exterior capping
- Insulation/sealing
