Types of Windows We Install
We provide an array of window styles and materials to match your home’s architectural character and performance goals:
Vinyl Windows
Vinyl windows are a top choice for California homeowners thanks to their affordability, low maintenance, and excellent thermal insulation. Made from PVC material, they resist warping, peeling, and fading even under intense sunlight. These windows provide excellent value and are Energy Star® certified for superior energy savings.
Aluminum Windows
Aluminum windows are ideal for modern homes that demand clean lines and durability. They provide exceptional strength, slim profiles, and long–lasting performance. While not as insulating as vinyl, modern aluminum frames often include thermal breaks to improve efficiency.
Fiberglass Windows
Fiberglass windows combine the aesthetics of painted wood with the durability of composite materials. They resist swelling, rotting, and corrosion, making them perfect for California’s varying climate zones, from coastal humidity to inland heat.
Wood-Clad Windows
Wood–clad windows provide timeless beauty with a protective exterior layer of aluminum or vinyl. They deliver the warmth and charm of traditional wood interiors while safeguarding against moisture, UV exposure, and termites.
Energy-Efficient & Low-E Glass Options
We offer Low-E (low emissivity) glass, double-pane, and triple-pane configurations designed to minimize UV radiation and heat transfer. These options help maintain indoor comfort while protecting your furniture from fading.
