1. Record what’s happening
Capture the symptoms, prevent further damage where it’s safe to, and note any relevant history.
2. Evaluate the house and site
Flashing method, sill condition, frame material, the glass package, and trim restoration all pull as much weight as the unit being installed.
3. Write the scope down
A real scope names the prep, protection, materials, access, permits, testing, cleanup, finish restoration, exclusions, and change-order process.
4. Evaluate the proposals
Check credentials, then compare the reasoning and boundaries in each quote rather than just the final number.
5. Finish strong
Testing, cleanup, documentation, warranty terms, and ongoing maintenance responsibilities should all be confirmed before closeout.
