West Covina experiences hot summers, and inefficient windows can lead to heat intrusion and high energy bills.

For homeowners wanting more premium options, we also offer durable fiberglass, classic wood, and Fibrex composite windows, all of which provide exceptional insulation and aesthetic appeal.


Are installed into existing window frames, making them ideal for homes where the structure is intact but the windows need an upgrade. This method is efficient, cost-effective, and minimally invasive.
On the other hand, are designed for homes undergoing major renovations or newly built properties. These windows include a nailing flange and require exposed studs, allowing for full-frame installation with maximum customization and structural precision.
No matter your project, we’ll help you choose the right window installation method to meet your goals.
From classic to contemporary, we offer styles to suit every home and personal preference:
Versatile, with top and bottom sashes that open.
Side-hinged and swung outward for excellent ventilation.
Smooth operation and space-saving design.
Add dimension and charm to your home’s exterior.
Large, fixed panes that maximize natural light.
