What the Window Replacement Process Looks Like

Posted in Windows

When it comes to the decision between DIY and using a professional, homeowners must weigh the costs in time and money as well as the assurance of having a job done right. If something is going to take you several days to complete, but a professional can do it in hours with a guaranteed result, you have to decide which investment is worth it.

Window replacement is a perfect example of this.

Whether you're interested in replacing windows yourself or you're simply curious about all of the steps involved, this post is for you. Let's go over all the steps involved in replacing windows and why it's often best to turn to a professional window installation company for help.

Step 1: Gather Parts and Materials

First, you have to choose the type of window you'll use as a replacement. There are many energy-efficient windows these days that simply outperform older models. You can use the same type and size of window for the easiest process, or get a little more involved by changing the type. Either way, gather all of the required parts and materials ahead of time, such as the upper and lower sash, the jamb, the stop, the stool, the sill, meeting rails and more. While there are kits available, you will also need an arsenal of tools and get ready for a lot of work.

Step 2: Measure Everything

"Measure twice, cut once" is a common phrase you'll hear with window replacements and other tasks that are difficult to rework. This is especially important for replacement windows, as you don't want to get to the installation step and realize you have the wrong new window size. Start by measuring inside the old frame, then the outside frame, as well as diagonal measurements and sill angles.

Step 3: Remove the Sash, Weights and Liners

Start removing the old window by taking out the sash and prying off the jamb liners. You may need to unscrew stops or other components to get to the sash and liners, or pry it off using a crowbar or flat bar. Just make sure you leave the interior and exterior casings intact, as well as removing old sash weights (if they're still in place).

Step 4: Prepare the Frame

Prep the frame for your new window by scraping off chipping paint or loose material. Also, cover any holes, cracks or gaps with wood putty and sand everything smooth. If your window install involves insulation, you can prep the opening for it by pulling out any existing fiberglass and then boring holes (usually 3/8" in diameter) through the sill and up through the head jamb.

Step 5: Place Insulation and Caulking

Using low-pressure, minimally expanding foam (the type meant for windows and doors), shoot it into the holes you drilled earlier, as well as the side jambs (using the sash weight pockets). Allow the insulation to harden at least six hours before making it flush. Don't forget to caulk as needed.

Step 6: Install the New Window

Place the new window replacement onto the sill (from the inside of your home), tipping it up into the opening instead of starting at the top. Press it tightly against any casings or stops and loosely fasten or screw it down, in case you need to make any adjustments.

Step 7: Finalize the Look

Shim as necessary, making final adjustments and then fastening tightly once you're happy with the install. Once you're done, all you need to do is add some final caulking, then prime and paint the window as desired (which will also involve some time and attention to detail, especially if there are several glass panes separated by wood or other materials).
