Installing new windows is one step closer to a more beautiful home, with greater security and lower energy bills. The process of replacing your windows does not have to be a difficult one. In fact, it’s a project you can do yourself over the weekend. 

So without further ado, let us unravel the mysteries of window replacement.

Step 1: Remove Old Window

Replacing an entire window means that you will have to remove the window, casing, trim, and plate. In this process, the frame might also need adjustments. Don’t forget to remove the entire window casing, including the trim and sill plate.

Step 2: Adjust the Window Frame

After removing the window casing, it’s time to measure the window spaces. It is important to do this as accurately as possible. Run the tape from one side of the window jamb to the other side to measure the width. Measure at the top, bottom, and middle. Hopefully, all measurements are the same. If not, continue with the smallest measurement. You can do the same routine when measuring the height. Allow about a 1/4 inch gap on all sides for further adjustments and insulation.

Step 3: Install New Window

Before you do any nailing, caulking, or other non-reversible procedure, place felt wrap to keep moisture out. Apply this wrap to the exterior framing of the window. Start installing the wrap at the bottom of the window and work your way up.

Install the window from the outside by pushing it up until it sits neatly into the frame, then screw it into place. You can also add shims to the areas that need adjustment. Use screws and nails to secure the window as soon as it has been installed.

Step 4: Wrap The Window

Once your window is set in place, secure the fins with one more layer of window wrap. Window wrap is a key component to keep moisture out, so make sure it’s straight and does not crinkle or fold on itself.

Step 5: Insulate the window

For the insulation process, use expanding-foam sealant. Put it in the gap between the casing and the window, but be mindful that you don’t use too much insulation that it disables the window from working properly. After the foam dries, cut away the excess and install a new interior casing. Replace exterior trim if needed.
