Questions to ask before you sign
- How long have you held your state license, and can I see the number?
- Is this a full-frame replacement or an insert into my existing frame, and why that one?
- Who pulls the permit, and does this change trigger an egress check on a bedroom window?
- What flashing and sill pan will you use, and in what order do you install them?
- If my home was built before 1978, is your crew lead-safe certified for this job?
- What's the completion date in writing, and what happens if the schedule slips?
