Step by Step Installation Guide

Whether you decide to do this yourself or hire a contractor for this job, there are certain tools and machines you must have handy.

  • Tape rule
  • Hammer
  • Nails and screws
  • A 3mm drill
  • Staple gun
  • Screwdriver (flat-head)
  • An extra hand (if you are doing this yourself)

Now, here are the steps to take:

  • Step 1

If there is an old window, remove it completely using the screwdriver. Gently pull the sliding track out and clean the debris around the opening sides.

  • Step 2

Step 2

Take the measurements of the new window you want to install. Check its width, height, and depth. Compare this measurement to the opening it will be installed into. The opening should be 30mm higher and 20mm wider than the window but ensure that both depths are the same.

  • Step 3

You need to know the type of flashing to use. The installation company will decide which one will make the windows firmer and tighter. Others might use a support strip made of wood. This is nailed to the windows sill.

The flashing, on the other hand, can be stapled to the stud using a staple gun. Make sure you cross-check the support before starting the installation.

  • Step 4

Now that the support frame is firm, the new window slide can be placed in the opening. Adjust the sill accordingly. Measure 100mm, then put a mark at each stop. You can pre-drill holes using the 3mm drill on each mark you make.

  • Step 5

Hit nails on the drilled holes, but do not allow them to go in deep. Repeat this process on each side of the windows.

  • Step 6

Check if the installation is diagonal in each direction and if there are uneven areas or gaps by the frame. Ensure you move the windows gently to their correct position. Now, check if it slides as expected.

  • Step 7

Now that it is certain the slides are functioning properly. Drive the nails deep. Then the windows are ready for use. You can watch this video to see how to install the window.
