A Short Checklist For Better Decisions

• Is the proposal for a full-frame replacement or an insert, and what condition of the existing frame supports that choice?
• If the home predates 1978, what lead-safe procedures will be used during removal and cleanup?
• Are the measurements custom, and how will the contractor handle older openings that are not perfectly square?
• Can the contractor explain permit needs and any historic district review issues before the job starts?
