If you’re upgrading your home’s exterior, the details matter. James Hardie® trim boards add crisp, clean lines around windows, doors, corners, eaves, and fascia helping your home look sharper while reinforcing the edges that take the most weather exposure. Custom Exteriors installs Hardie® trim boards across Pleasanton, Concord, Walnut Creek, San Francisco, Fremont, and San Jose, pairing premium materials with expert workmanship for a finished look that lasts.
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.
