What Licensed Contractors Look for During a Window Replacement Estimate

The First Walk-Through Tells A Contractor Most Of The Story

A proper estimate is less about guesswork and more about reading the house the way an installer would on day one.

The best contractors start by looking at the opening itself.

Homes in Polk County may have a mix of old aluminum units, vinyl replacements, block construction, and additions that were not built at the same time as the rest of the house.

How Contractors Compare Window Options

If the goal is to reduce load on the AC, the glass package matters almost as much as the frame.
