Replacing basement windows can be a daunting task, but it’s one that can be completed with a little planning and preparation. By following these steps, you can ensure that your new windows are installed correctly and will provide years of trouble-free operation.
The first step is to remove the old windows. This can be done by carefully prying them out of the frame with a pry bar. Once the old windows are removed, you’ll need to clean the frame and remove any debris. Next, you’ll need to measure the opening for the new windows. Be sure to measure the width, height, and depth of the opening. Once you have the measurements, you can order your new windows.
Identifying the Type of Window
Before embarking on the replacement process, it’s crucial to correctly identify the type of window you have. Accurately determining the window type ensures that you purchase the right replacement window and avoid costly errors. Here’s a detailed guide to help you identify your basement window type:
1. Hopper Window:
Hopper windows are hinged at the bottom and open inward from the top. They provide excellent ventilation and are commonly found in basements and crawl spaces. Key features of hopper windows include:
| Characteristic | Description |
|---|---|
| Hinged Position | Bottom |
| Opening Direction | Inward from the top |
| Common Locations | Basements, Crawl Spaces |
2. Casement Window:
Casement windows are hinged on one side and open outward like a door. They offer a wide opening for ventilation and easy access. Basement casement windows may have a crank mechanism for opening and closing.
3. Slider Window:
Slider windows consist of two sashes that slide horizontally over a track. They provide easy ventilation and are space-saving options in smaller basements. Basement slider windows typically have a vinyl or aluminum frame.
4. Awning Window:
Awning windows are hinged at the top and open outward from the bottom. They are similar to hopper windows but offer increased protection from rain and debris. Basement awning windows are often found in conjunction with other window types.
5. Fixed Window:
Fixed windows are non-operable and provide natural light without the ability to open. They are often used in combination with other window types or in areas where ventilation is not required.
Removing the Old Window
Replacing basement windows can be a DIY project with careful planning and the right tools. Here’s a step-by-step guide to removing the old window:
Step 1: Gather Tools and Materials
Before starting, gather the necessary tools and materials, including a pry bar, screwdriver, hammer, chisel, utility knife, and new window.
Step 2: Remove Interior Trim
Carefully remove the interior trim around the window using a pry bar. Be gentle not to damage the drywall or window frame.
Step 3: Remove Exterior Trim
Go outside and remove the exterior trim around the window. If there are nails or screws holding it in place, use a screwdriver or hammer to remove them.
Step 4: Cut Caulk
Use a utility knife to cut the caulk around the window frame on both the interior and exterior sides. This will help loosen the window and make it easier to remove.
Step 5: Remove Window
Use a pry bar to gently pry the window loose from the frame. Be careful not to damage the frame or the window itself.
Step 6: Clean Opening
Once the old window is removed, clean the opening thoroughly of any debris, caulk, or sealant. This will ensure a good seal for the new window.
Preparing the Window Opening
Before installing the new windows, it’s crucial to prepare the window opening to ensure a proper fit and seal. Here are the steps to follow:
1. Remove the Old Window
Carefully remove the old window by unscrewing any fasteners or nails holding it in place. Pry the window frame gently from the opening, taking care not to damage the surrounding structure.
2. Inspect the Opening
Once the old window is removed, thoroughly inspect the window opening for any damage, rot, or moisture issues. Repair any deficiencies by replacing damaged wood, sealing any leaks, or adding insulation as necessary.
3. Frame the Opening
In most cases, the existing window opening will need to be framed to accommodate the new window. This involves:
| Step | Description |
|---|---|
| a. Measure and cut framing lumber | Measure the height and width of the new window and cut the framing lumber accordingly. |
| b. Attach the header and sill | Secure the header (top) and sill (bottom) framing lumber to the opening using appropriate fasteners. Ensure they are level and plumb. |
| c. Install jambs (sides) | Attach the jambs (sides) of the window frame to the header and sill using screws or nails. Make sure they are vertically straight and flush with the inside edge of the opening. |
Once the framing is complete, double-check its dimensions and alignment to ensure a snug fit for the new window.
Installing the New Jambs
With the old jambs removed, it’s time to install the new ones. This process is similar to removing the old jambs, but in reverse. Start by placing the new jambs in the rough opening and securing them with screws.
Once the jambs are in place, you’ll need to install the window stop. The window stop is a thin strip of wood that fits into a groove in the jamb and holds the window in place. To install the window stop, simply insert it into the groove and nail it in place.
With the window stop in place, you’re ready to install the window. To do this, simply lift the window into the opening and set it in place. Once the window is in place, you’ll need to secure it with screws.
Finally, you’ll need to caulk around the window to seal it from the elements. To do this, simply apply a bead of caulk around the perimeter of the window and smooth it out with your finger.
Here is a table summarizing the steps for installing new jambs:
| Step | Description |
|---|---|
