Window Installation: What Goes Into the Process ?

What exactly goes into a window installation process? Well, many homeowners decide to replace their windows for a variety of reasons. Some do it only for aesthetic reasons to improve their home’s curb appeal and saleability. Others, on the other hand, do it to improve the energy efficiency of their home, to enhance their natural lighting, to get rid of air leaks and drafts, to improve the overall comfort of their home, or to change a damaged window frame, among other reasons. 

So, what can you expect from a window installation process? What are the steps that you should take into account? 

Hiring the best contractor

One of the first stages in the window installation process is finding and hiring the right contractor that’s able to meet all the highest standards in the industry. 1-800-HANSONS has been awarded a Gold Badge by Consumers Energy.

Window measurements

After you’ve selected a qualified contractor, the next step of the window installation process is to get precise measurements. All window replacements are made to the exact specifications of the customers. Accurate measurements will ensure that there won’t be any air leaks, water infiltration, or other forms of damage. They will also provide proper protection from the elements. Usually, the contractor will schedule an appointment to visit your home and take these measurements. 

Old window removal

Work begins once the new windows are ordered and the replacements have arrived at your home. In most cases, your installation contractor will also be the one that will remove the old windows. It’s crucial that the original weather barrier isn’t cut too far, and that all traces of sealant from the old windows are removed. Following these steps will ensure that the new sealants adhere properly.


This part of the process is probably the most important one, and it is where choosing a qualified contractor will be most significant. If done incorrectly, weatherproofing often leads to expensive repairs and replacements down the line.

Finally, comes the window installation process. Contractors will have to pay extra close attention to fold out the windows nailing fins before lifting the window to the opening. They should then set the window’s sill into the bottom part of the opening and gradually push the frame until all the nailing fins are flush against the wall.

The installer uses a level to properly align the window with the opening. The window keeps air out by adding waterproofing material and sealants. Foam sealants are among the most popular for this last part of the process.
