The direct answer
What full-frame window replacement involves
Full-frame window replacement removes the existing unit and more of its frame so the opening can be assessed and a new assembly connected to the wall. The proposal should identify removal limits, opening repairs, air and water details, trim, finish work, and the concealed-condition process.

A practical path forward
From first notes to a final walk-through
Use the same sequence with each company so proposals are easier to compare and important scope questions do not get lost.
- 1
Confirm why the frame is being removed
Ask which observed condition or project goal supports the broader method.
- 2
Define the opening scope
Document removal, repairs, flashing, fastening, insulation, and finish responsibilities.
- 3
Align concealed-condition rules
Put allowances, exclusions, and change-order approval in writing before work begins.

Before you compare totals
Use a quote-ready checklist
A complete proposal makes it easier to spot exclusions and avoid comparing two different projects as if they were the same.
- Reason for full-frame method
- Removal and retained components
- Opening repair allowance
- Flashing and sealing scope
- Trim, finish, cleanup, and disposal
