Installing The New Window

Proper alignment of your new window ensures a perfect fit within the stucco opening. Begin by setting the window into the rough opening. Use a level to check for horizontal and vertical alignment. Adjust with shims until the window sits squarely in place.

Sealing the window is critical to prevent water and air leaks. Apply a bead of quality caulk around the window’s perimeter. Firmly press the window against the opening to distribute the caulk evenly. Secure it with screws, making sure not to overtighten and warp the frame.

Matching the stucco color and texture around your new window is vital for a seamless look. Apply a layer of stucco patch to cover the gaps. Smooth it out to match the existing wall. Let the stucco cure before paint matching to finalize the project.

Finishing Touches And Clean-up

To ensure longevity, apply weatherproof seals around the new window. Use a high-quality sealant for the best protectection against the elements.

Proper insulation is also crucial. It keeps your home cozy and energy-efficient. Install the insulation with care.

After installation, clean the window thoroughly. A non-abrasive cleaner will do the job. Then, polish the glass for a streak-free finish.

Lastly, safely discard old window materials. Keep the area free of debris. This ensures a clean and safe work space.
