Formerly Offering Anlin Windows
Thank you for visiting our page about Anlin Windows. While Custom Exteriors previously carried the Anlin line, we have since made the decision to focus exclusively on premium fiberglass replacement windows.We found that fiberglass delivers unmatched durability, energy efficiency, and long-term value for Pleasanton area homeowners compared to vinyl.
Unlike vinyl, fiberglass won’t warp, crack, or become brittle in our region’s varied climate. It also offers a cleaner, more modern aesthetic and higher return on investment for homeowners looking to upgrade. If you came here looking for Anlin, we invite you to explore our Infinity from Marvin fiberglass windows, which outperform vinyl in every key category:
Strength & Longevity: Fiberglass frames are 8x stronger than vinyl, ensuring decades of reliable performance.
Energy Efficiency: Designed to keep your home comfortable year-round while lowering utility bills.
Beauty & Customization: Slimmer frames, more glass, and a wide range of finishes and styles to complement your home.
Low Maintenance: No warping, fading, or swelling—just lasting performance. At Custom Exteriors, we remain committed to offering the best products available—and today, that means fiberglass windows.

Longevity, Security, and Energy Efficiency
For homeowners in Pleasanton and throughout the Tri-Valley, fiberglass is one of the best window material choices for long-term energy efficiency and durability. Fiberglass windows are highly resistant to weather, dents, and everyday wear, making them especially well-suited for the region’s warm summers and seasonal temperature swings. They’re easy to clean, require virtually no maintenance, and never need to be refinished. Thanks to their excellent thermal performance, fiberglass windows can help keep energy bills noticeably lower over time. They’re also manufactured using minimal natural resources, making them one of the more eco-friendly window options available for Tri-Valley homes.
