Answers For All of Your Replacement Window Questions

Replacement Window FAQs

How do you measure for replacement windows?

When replacing windows, precise measurements are pivotal in ensuring a proper seal. For this reason and more, we highly recommend having a professional take measurements prior to ordering replacement windows. If you’d still like to know how to take your own measurements, measure the following:

  • Horizontal width: Take three measurements: top, middle, and bottom. After taking these measurements, you’ll want to use the smallest of the three numbers.
  • Vertical height: Again, take three measurements: left, middle, and right, and use the smallest number as your final measurement.
  • Depth: Be sure to take this measurement on all sides of your window.

How much does it cost to replace windows?

At Window World of Huntsville, we carry window styles suited for a wide range of budgets.

How do you measure windows for blinds?

Depending on whether you wish to install inside mount blinds or outside mount blinds, the process for measuring will differ. Find out what style of blinds you wish to install, and follow the steps below for proper measurements:

  • Inside mount blinds:
    • Measure your window frame’s depth.
    • Measure your window’s width in three places: top, middle, and bottom. Use the smallest of these numbers as your final measurement.
    • Measure the height of your window in three places: left, right, and center. Depending on the type of blinds or shade you are installing, you will either use the smallest or the largest of these measurements.
    • Do not deduct anything from your width or height measurements, as manufacturers will already account for allowances and deductions.
  • Outside mount blinds:
    • Measure the width you would like your blinds to cover, including at least 1 ½” on both sides for optimal coverage.
    • Measure height, starting from the point your blinds will be hung, down to the window sill. Be sure to leave 1 ½” – 2” of overlap on top to account for your blinds’ mounting hardware.
    • Again, do not deduct anything from your measurements, as this will be accounted for by manufacturers.

How do you clean windows?

A clean window and a dirty window make a dramatically different impression. To keep your windows shining like new, follow these simple steps:

  • Use a vacuum to clean larger dust and debris.
  • Use a soft cloth with soapy water to clean your window sash and frame.
  • Wipe the glass panes using a paper towel (or lint free wipe) and a glass cleaning solution, either store bought or homemade.
  • Remove your window screens and wash them using a simple combination of soap and water. Be sure to allow your screens to air-dry after cleaning.

How do you replace a window screen?

Window screens play an important role both functionally and aesthetically. If your screen shows signs of any major damages, holes or tears, be sure to replace them as soon as possible. To replace your window screen, follow these simple steps:

  • Remove the window screen from your window.
  • Laying your screen flat, remove the current window screen mesh from the grooves that hold it in place.
  • Roll out and stretch the replacement screen mesh over your window screen frame, leaving some extra room along the edges, and cut using your tool of choice.
  • Use a spline roller to push your new screen mesh into the grooves of your screen’s frame.
  • Once the new mesh is secure, trim the extra material along the edges.
  • Reinstall your finished window screen.

What is a window sash?

The sash is the part of the window which holds together glass panes and their component parts. Window sashes are fitted to the window frame and, depending on the style of your windows, can be either stationary or mobile. Double hung windows, for example, feature window sashes which move up and down to allow for fresh air to circulate through home.
