Know What You Need Before You Hire Anyone

• What happens if hidden damage is found after removal?
• What does the warranty cover, and who services it?
• Can you show recent projects that are similar to my house and location?

When a company can explain the permit path, recommend the right product, and install it cleanly, you are usually in good hands.
