DMac shares his home improvement expertise

Few home improvement projects make as much a difference as replacing your old, drafty windows. The single-paned windows that were once standard in our homes are now something from the past. While window replacements are often done by a major home improvement company, it’s always nice to have some information on how to install your replacement windows yourself. In this blog, we’ll be going over how to install replacement windows so that you can get an idea of how the process follows.

1. Measure your Windows

The very first thing you have to do is measure your windows. Start by measuring the inside of one window jamb to the opposite jamb at the bottom, middle, and top, both horizontally and vertically. Choose the smallest measurement when ordering your windows. Measuring your windows has to be done with exact precision. If done incorrectly, you’ll order an incorrect sized window that will either not fit in the opening, or will require some extra work to fix it properly. The benefits of working with a professional is that you will eliminate the chances of making a mistake in the measurements, which could many times cost you more than working with a professional.

2. Remove the Window Stops

Use a pry bar and hammer to carefully pry away the window stop molding from the top and sides of the window frame. You may be able to reuse the stop moldings if removed carefully. However, if your stop moldings are old and brittle, it may be easier to simply buy and install new moldings.

3. Remove the Inner Sash

Meticulously remove the inner window sash from the opening and remove the knotted weight cords from the holes on the sides of the sash frame. Sometimes they can be nailed into the sash frame.

4. Remove the Parting Stops

Use a small pry bar or a flat screwdriver to remove the narrow parting stop moldings that separate the inner window from the window’s outer sash. These parts will not be reused, so feel free to break them if you’re having a hard time freeing them from the window frame.

5. Remove the Outer Sash

Now that the parting stops are removed, the outer window should be able to slide out of the frame. Go ahead and free it from the sash cords by pulling the knots out of their openings on the sides of the sashes frame.

6. Remove the Counter Weights and Pulleys

Next, open the weight pockets on the sides of the window frame and remove the heavy weights. Cut the sash cords and remove the cords. After that, unscrew the pulleys that are located at the top of the window frame.

7. Test-Fit Your New Window

Now test fit the window in the frame opening and shim it into place. You will need a carpenter’s square and a torpedo level to adjust the window, so it’s level and square.

8. Secure the Window

Once you’ve ensured that the window will fit properly, remove it from the opening and apply caulk to the window’s frame according to your window’s specific instructions. Reinsert the window and adjust for level using a framing square and a torpedo level. Utilize shims to slightly wedge the window in place.

Test both sashes to ensure the window glides smoothly. If the sashes are too tight, use the adjustment screws (located in the side channels) to adjust it. If this does not solve the problem, then you may have to replace the shims you used with thinner ones.

Once your window fits properly and the sashes move freely, drive in mounting screws through the channels on the sides and into the window frame to secure in place. Be sure not to overtighten the screw as it can pull the sash frame out of the square.

9. Caulk the Joints

Now slide the header piece up to eliminate gaps and apply the recommended caulk to the joints on both sides of the window. Carefully follow the manufacturer’s instructions as some windows require leaving a gap at the bottom for drainage.

10. Install the Window Stops

Next, reattach the window stops around the top and sides of the new replacement window using screws or a brad nailer.

11. Caulk & Paint

Finally, complete the replacement window installation by caulking the joints located around the stop moldings. If needed, finalize with whatever painting may be needed.
