How to Choose a Trustworthy Window Installer in Knoxville, TN

Signs You Are Dealing With A Careful Installer

1. They look at the opening, not only the window itself. 2. They mention flashing, insulation, and air sealing, not just the brand name. 3. They put the warranty in writing and explain what it covers. 4. They give a timeline that sounds realistic, not overly optimistic. 5. They answer questions without making you feel rushed.
