Permits, Historic Homes, And Other Local Complications

• Is the quote for an insert replacement or a full-frame replacement?
• Does the price include interior and exterior finish work?
• Are permits or inspections included if they apply?
• What happens if rot or damaged framing is uncovered?
• How long is the product warranty and the labor warranty?

The strongest bids usually come from contractors who explain the trade-offs rather than just advertising the lowest figure.
