What to Expect During a Professional Window Installation in Knoxville

If you have never had windows replaced before, the process can feel a little opaque.

What Good Installation Looks Like In Practice

• Is the window opening square and stable before the new unit is set?
• Is the installer using proper sealing materials around the perimeter?
• Can the window open, close, and lock without binding or scraping?
• Do the caulk lines look neat and complete rather than smeared or thin?
