Where Hardie® Trim Boards Are Used



Window and Door Trim
Properly installed Hardie® trim creates crisp framing and visual contrast that makes windows and doors stand out while giving the entire façade a more polished, finished look. It also helps protect vulnerable edges from moisture and wear, combining style with long-term durability.

Corner Boards
Corner boards help define the edges of your home and give the exterior a clean, structured appearance. Hardie® corner boards add depth and visual strength to each elevation, creating sharp lines that enhance architectural detail. Beyond aesthetics, they also provide added durability at key transition points where siding meets and weather exposure is greatest.Hardie soffit panels provide a smooth, uniform finish that complements both classic and contemporary Bay Area architecture. They integrate seamlessly with other fiber-cement siding products for a cohesive, high-end exterior look.

Fascia and Rake Boards
Fascia and rake boards finish the roofline and bring the entire exterior design together. Hardie® fascia and rake trim create clean, consistent lines along eaves and gables while standing up to sun, moisture, and temperature changes common in the Bay Area. The result is a more cohesive, well-defined exterior with long-lasting protection where your home meets the roof.

Batten Boards
Batten boards are used to create classic board-and-batten accents that add texture and visual interest to your home’s exterior. Hardie® batten trim delivers clean vertical lines that work beautifully on gables, entryways, and accent walls. It’s a timeless design detail that adds character while maintaining the durability and low maintenance homeowners expect from fiber cement.

Accent Band boards
Accent band boards introduce horizontal lines that help break up tall or wide elevations, adding depth and visual balance to the exterior. Hardie® accent bands are often used between siding styles or floors to create architectural separation and highlight design features. When installed with precision, they add subtle detail that elevates the overall look without overwhelming the home’s design.

Why Homeowners Choose Hardie® Trim for Bay Area Homes

Hardie® trim boards are a smart upgrade across a wide range of Bay Area communities. In Pleasanton, they’re ideal for modernizing trim lines on homes throughout neighborhoods like Vintage Hills and Ruby Hill. In Walnut Creek, Hardie® trim helps elevate curb appeal in established neighborhoods where exterior details make a lasting impression. San Francisco homes rely on durable trim solutions that can stand up to fog and moisture, while Fremont is a great fit for contemporary designs and clean architectural lines. In San Jose, Hardie® trim boards perform exceptionally well on homes exposed to intense sun and heat, where traditional trim materials often wear down more quickly.

"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."
