How to Measure for Replacement Windows in Pasadena TX

Measure The Opening Before You Think About Glass

A replacement window measurement starts with the opening, not the old sash you can see from the room.

In older Pasadena TX houses, wood frames can swell, settle, or hide past repairs, so a quick eyeball estimate usually misses something important.

Before measuring, open the window fully if it operates, remove any screens that block access, and look for obvious rot, loose caulk, or damage around the jambs.

If you are comparing notes with a contractor, this is also the point where an experienced window replacement company can tell you whether you are looking at a standard replacement or a more involved frame repair.

Take Three Measurements Every Time

For each window, measure the width at the top, middle, and bottom of the opening.

Use a steel tape measure, not a cloth tape, and keep the tape straight from edge to edge.

When the three height numbers do not match, use the smallest one.

Round carefully and keep a clean record, because a half inch error can turn into a costly re-order.

When To Hand The Job To A Pro
