Formerly Offering Anlin Windows | Custom Exteriors Fiberglass Replacement

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 East Bay homeowners compared to vinyl.

Unlike vinyl, fiberglass won’t warp, crack, or become brittle in our region’s varied climate—from hot summers to cool, damp winters. 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.

Benefits of Fiberglass Windows

Fiberglass windows are a smart choice for East Bay homes because they’re built to handle the region’s unique climate. Unlike vinyl, fiberglass won’t warp, crack, or fade under extreme temperature swings, so your windows look great and perform well for decades. They’re also highly energy efficient, helping keep your home cooler in the summer and warmer in the winter, which is essential for managing utility costs in our variable weather. Plus, fiberglass requires very little maintenance, giving East Bay homeowners lasting beauty and peace of mind without constant upkeep.

Superior Durability

Fiberglass is incredibly strong and resistant to warping, rotting, swelling, and cracking. Unlike vinyl or wood, it can withstand extreme temperature changes and weather conditions, making it a long-lasting investment.

Energy Efficiency

Fiberglass frames are excellent insulators and can be paired with high-performance glass to reduce energy loss. This helps keep homes cooler in summer, warmer in winter, and lowers utility bills year-round.

Low Maintenance & Lasting Beauty

The beauty of Anlin windows lies in their versatility. Available in a wide variety of styles, sizes, and designs, these windows cater to every architectural preference and need. Whether you're after a traditional look or a more contemporary feel, Anlin windows are sure to enhance your home's curb appeal.

A Lasting Investment in Window Replacement

Beyond durability and energy savings, fiberglass windows also enhance the curb appeal and value of East Bay homes. Their slim frames allow for larger glass areas, letting in more natural light and showcasing scenic views of hills, redwoods, and neighborhoods throughout Pleasanton, Walnut Creek, and beyond. With a wide range of styles and finishes, homeowners can match any architectural look, from classic ranch homes to modern builds, while knowing they’ve invested in windows that combine beauty, strength, and long-term performance.

"Loved working with Custom Exteriors. Very responsive to inquiries. Precise in their measurements, estimate and timeframe for completion. Highly recommend them."

"Custom Exteriors provided a great product and good service in replacing 2 sliding glass doors and 2 other windows in my townhouse. One was a custom window that required extra work in refitting the plantation shutters to the new window. Although there were some bumps along the way, Jeff and his foreman Ryan excelled at follow up. I would recommend Custom Exteriors."

"Kevin one of the owners of Custom Exteriors contacted me the following day and immediately tried to make things right. The first thing, I was impressed about was he took my call without hesitation. Many medium sized business will bounce me around to different people before finally being able to talk to the owner. He was an attentive listener and took to the time understand my needs and wants in an exterior entry door.His communication was top notch, sending me estimates the same day or the following day. He gave me choices in fiberglass doors: ProVia and Therma-Tru, hardware: Trilennium vs Emtek, and single point vs multiple point locks. I just ordered a ProVia doors through Kevin. This surprised both to my husband and me. Before contacting Custom Exteriors, we thought we were going to get a Therma-Tru door, but that totally changed once we the information we needed from Kevin. I get the sense that he truly wants to give customers options and information, but respects the customer's final decision. There is not high pressure sale pitch. Kevin wants customers to be informed and happy with the end product."
