Embarking on a window replacement project brings an opportunity to upgrade your home's aesthetics, functionality, and energy efficiency. Andersen windows, renowned for their quality and craftsmanship, offer a range of options that cater to diverse needs and styles. This comprehensive guide walks you through the Andersen window installation process, ensuring a smooth and accurate result.
Before you begin, ensure you have the right tools and materials. You'll typically need a ladder, tape measure, drill, level, safety glasses, gloves, and caulk. Gather your Andersen windows and corresponding hardware. Depending on your window type, you might also need a skill saw, utility knife, or circular saw.
Preparation and Measuring
Accurate measuring is crucial for a perfect fit. Andersen windows come in standard and custom sizes. For standard sizes, measure your existing window openings. For custom sizes, measure your rough opening, which is the space between the framed parts of your walls where the window will be installed.
Make sure to account for any variations between the walls and the window dimensions. Andersen recommends adding 1/4" to the width and 1/2" to the height when ordering custom-sized windows to accommodate typical wall framing variations.
existing Window Removal
Begin by removing your existing window. This involves removing the sash (the moving part of the window) and the frame (also called the jamb). Use a utility knife to cut any caulk around the window. Then, carefully pry off the window stops using a screwdriver or pry bar. Remove the sash and jamb, taking note of any unique features or installations that may need special attention during reinstallation.
For double-hung windows, you might need to remove both sashes and the frame as a single unit. Use a claw hammer to gently tap out the nails or screws holding the frame in place. Ensure you understand your window type and remove it accordingly to avoid damage.
Checking for Square
Before installing your new Andersen window, check that the rough opening is square. Use a level to ensure the sides and top of the opening are perpendicular. If they're not, you may need to shim the opening to create a square frame for your new window.
Address any gaps between the rough opening and the new window's frame. Andersen recommends shimming the opening with wooden shims to create a flat, level surface. This ensures your window sits securely and squarely in the opening.
Installing Your Andersen Window
Now that your rough opening is prepared, you're ready to install your new Andersen window. Begin by placing the new window into the opening from the top. Ensure it's level and plumb. Once you're satisfied with its position, temporarily secure the window in place with two clips provided by Andersen – one on the header and one on the sill.
After securing the window, use a level to check its plumbness and levelness. Make any necessary adjustments. Once you're happy with the window's position, proceed with the permanent installation.
Installing the Window Frame
Andersen recommends installing the window frame in sections. Begin by placing the top jamb (header) into the frame. Ensure it's level and flush with the top of the window. Attach it using the screws provided, spacing them evenly along the jamb.
Next, install the side jambs. Start with the jamb that will be nailed or screwed to the framing. Ensure it's plumb and flush with the other jamb. Secure it with nails or screws, spacing them about 16" apart. Then, install the other side jamb, ensuring it's flush with the first jamb. Secure it in place.
Installing the Window Sill
Once the jambs are installed, it's time to add the sill. Andersen recommends using a slope away from the interior of the house to facilitate water runoff. Ensure the sill is square and level, then secure it with screws or nails spaced about 16" apart.
Now, apply a continuous bead of latex-lute caulk around the perimeter of the window. This helps keep out drafts and moisture. Ensure you cover all gaps and nail or screw holes.
Adding the Interior Jambs
Andersen windows come with interior jambs to provide a finished look and facilitate easy operation of the window. Install these jambs by placing them into the window frame. Use finish nails to secure them in place.
Remember to account for any stop material and trim you plan to add to complete your window installation. Andersen recommends reinstalling window stops after your window is fully operational to ensure proper functionality.
Finishing Touches
With your Andersen window installed, it's time to finish the job. Andersen suggests adding a drip cap above the exterior window to deflect water away from the window and untreated wood. This can help prevent water damage and rot.
Finally, apply a bead of caulk around the exterior perimeter of the window. This helps create a weather-resistant barrier and seals any gaps between the window and the surrounding wall. Ensure you use a caulk that's compatible with your window's finish and resists fading, cracking, and peeling.
Congratulations, you've successfully installed your Andersen window! Regular cleaning and maintenance, such as checking and tightening screws, cleaning the tracks, and checking for any signs of wear, will help ensure your window continues to function optimally and maintain its appearance.
