Measuring Your Windows Correctly for Replacement in Madison AL

The Basic Measurement Process Homeowners Can Follow

Another oversight is checking only from one side of the opening when the trim or frame condition is questionable. A good window choice can still disappoint if the opening itself is not ready for it.

Even similar windows in the same house can differ enough to matter. Measure each opening on its own and label the notes clearly.
