1. Observe and protect
Document what's happening, limit additional damage where you safely can, and collect background on the home's history.
2. Evaluate the house and site
Assessment includes installation approach, flashing, sill condition, frame material, glazing, and trim restoration, weighed alongside the window itself.
3. Define a written scope
Put in writing the prep work, protection plan, materials, access needs, permits, testing, cleanup, restoration, exclusions, and change-order process.
4. Compare providers
Verify credentials first, then look at the reasoning and scope limits behind each proposal rather than fixating on the total.
5. Inspect closeout
Closeout means verifying testing, cleanup, documentation, warranty paperwork, and understanding what maintenance responsibilities remain.
