Why It’s Important to Measure Correctly for Replacement Windows


If you want to replace older windows with newer ones, you’re making a great decision. Older windows simply can’t compare to the energy savings, UV protection, sound resistance and style of newer replacement windows. Before you order from an online retailer or pop off to a home improvement store to buy windows, however, you need to take the time to measure carefully. This can be the difference between an effortless experience that saves you money with your window installer and a total nightmare that sends you back multiple times.

Why It’s Important To Measure Replacement Windows Correctly

Most of the time, close is good enough, but not with windows. Anything too small is going to cause you problems with moisture penetration and energy efficiency, and too big won’t fit. Always measure to 1/16 of an inch. For double-hung windows, start by measuring the width, then measure the height. Always take three measurements: top, mid and bottom. Pull the tape measure from the left pocket all the way to the right. Hopefully, all three measurements will be the same. If not, go with the smallest of the three. The final measurement is what you get after subtracting 1/4″ from the number.

How a Window Installer Can Help

Many professional window installers go beyond taking care of actual installation. They can also give you a hand with the measuring and selection process for replacement windows. Not all windows are made equal when it comes to performance or style. This offers many benefits:

  • Less risk of mistakes
  • Better energy efficiency
  • Attractive window options
  • Increased comfort
  • Excellent interior and exterior appearance
  • Long-lasting performance

Put simply, when you work with a replacement window expert who has decades of experience, you make better choices. A pro can recommend the best windows for your priorities, making your home comfortably cool in summer and warmer in winter. At the same time, professionals help you stay within your budget.
