Why Choose Hardie® Plank Lap Siding?

Authentic Wood Look—Without the Upkeep
‍Hardie Plank captures the charm of real wood siding with deep, realistic grain and crisp shadow lines. Unlike wood, it won’t warp, crack, rot, or attract termites which makes it a smart, long-term investment.

‍Built to Stand Up to the Elements
James Hardie siding is engineered for specific regional climates. For Northern California, Hardie Plank resists moisture, wind, sun exposure, and coastal conditions common throughout the East Bay and San Francisco Bay Area.

‍ColorPlus® Technology for Fade-Resistant Beauty
‍Available in a wide range of pre-finished, baked-on colors, Hardie Plank’s ColorPlus Technology ensures long-lasting color that resists fading, peeling, and chipping. Your home stays vibrant for years with minimal maintenance.

‍Fire-Resistant Construction
‍Fiber cement siding is non-combustible which is an important advantage for California homeowners concerned about wildfire risk. Hardie Plank complies with fire-rated construction requirements and can provide added peace of mind.

‍Low Maintenance & Long Lifespan
‍Unlike vinyl or wood, fiber cement requires far less upkeep. A simple cleaning once or twice a year keeps it looking fresh. This siding is designed to last decades with proper installation.

The Hardie® Advantage in the East Bay & San Francisco Bay Area

Homes throughout Pleasanton, San Ramon, Walnut Creek, Livermore, Danville, Dublin, and the surrounding Bay Area benefit from Hardie Plank’s durability and climate resilience. From fog and moisture near the coast to heat in the Tri-Valley, Hardie Plank is engineered to perform.

"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."
