Perched in the wooded foothills above Silicon Valley, Los Altos Hills is a semi-rural Santa Clara County town of one-acre lots, oak-studded ridgelines, and custom ranch, Mediterranean, and contemporary estates. The Mediterranean climate delivers hot, dry summers and cool, damp winters, while morning fog rolling off the Bay and afternoon sun on west-facing slopes create real temperature swings that stress older siding and single-pane windows. Because much of town sits in the Wildland-Urban Interface against the Santa Cruz Mountains, where CAL FIRE maps designate high and very high Fire Hazard Severity Zones, a tight, well-sealed exterior envelope isn’t just about curb appeal—it is a first line of defense against ember intrusion, moisture, and heat.
Heritage Exteriors installs James Hardie fiber cement siding that is non-combustible and Class A fire-rated—an ideal match for Los Altos Hills’ foothill setting and California’s Chapter 7A ignition-resistant building requirements. Fiber cement resists the wood-boring pests, dry rot, and UV fading common in the foothills, holding its finish through decades of sun and winter rain. We pair it with energy-efficient, dual-pane windows that cut solar heat gain on sunny slopes, dampen road noise, and keep interiors comfortable across the region’s wide day-to-night temperature range, all while helping homeowners meet California’s Title 24 energy standards.

Are your windows single-pane, difficult to operate, or showing signs of wear and tear? It’s time for an upgrade. Replacing old, inefficient windows provides a host of benefits for Los Altos Hills homeowners. Our replacement services are focused on:
Many prudent Los Altos Hills homeowners choose to replace their siding and windows concurrently. This holistic approach offers several key advantages:
We provide a carefully selected range of siding materials chosen for their superior performance, beauty, and suitability for the safety-conscious and discerning tastes of Los Altos Hills.
Fiber cement siding, particularly from industry leader James Hardie, is the premier and most highly recommended investment for a Los Altos Hills home. It is non-combustible, providing the highest level of fire protection (Class A rating). It is also exceptionally resilient, resisting rot, pests, and impact, and its advanced ColorPlus™ Technology finishes are engineered to resist fading from intense UV exposure, ensuring your home looks beautiful for years with minimal maintenance.
While we prioritize non-combustible materials for safety, we can source and install fire-treated traditional wood siding and advanced engineered wood products like LP SmartSide® for specific architectural applications where permitted. These materials can provide a natural aesthetic that complements the town’s rural character.
Complementary Exterior UpgradesTo give your home a truly finished and protected look, we also specialize in installing and repairing trim, soffit, and fascia using durable, non-combustible or fire-resistant materials. These elements are essential for protecting your roofline and walls. We also provide professional exterior painting with durable, fade-resistant formulas and seamless gutter systems with leaf guards to manage winter rains and reduce combustible debris buildup.
An investment in new siding and windows delivers tangible benefits that enhance your lifestyle and protect your property’s value in the exclusive Los Altos Hills environment.
This is the paramount benefit for any Los Altos Hills homeowner. High-performance, non-combustible siding and properly sealed, dual-pane tempered glass windows form a formidable barrier against embers and radiant heat, creating defensible space and providing invaluable peace of mind for your family and investment.
The warm, sunny days can lead to high cooling costs. High-performance insulated siding and ENERGY STAR® windows with low-SHGC glass create a powerful thermal barrier, keeping your home cooler and more comfortable while significantly reducing your energy bills.
An exterior remodel is one of the most effective ways to elevate your home’s curb appeal and ensure it adheres to the highest architectural standards. In the ultra-competitive Silicon Valley real estate market, a high-quality, architecturally appropriate, and fire-safe exterior adds significant value.
Upgrading to well-sealed siding and modern windows with high acoustic ratings can substantially decrease outside noise, enhancing the peaceful, semi-rural character of your Los Altos Hills estate and creating a more serene indoor environment.

Yes. Much of Los Altos Hills lies in the Wildland-Urban Interface against the Santa Cruz Mountains, and CAL FIRE maps portions of town in High and Very High Fire Hazard Severity Zones. That makes non-combustible, Class A fire-rated materials like James Hardie fiber cement a smart, code-conscious choice under California’s Chapter 7A ignition-resistant requirements.
Fiber cement is our go-to for the foothills because it shrugs off intense summer sun, winter moisture, and wood-boring pests without rotting or warping. Unlike natural wood, it won’t feed a fire or fade quickly under UV exposure, and it keeps its factory finish for decades in this Mediterranean climate.
Yes. Exterior work in Los Altos Hills is permitted through the Town’s Building Division, and projects in designated fire hazard zones must meet Chapter 7A ignition-resistant standards. Window replacements also need to comply with California’s Title 24 energy code. Heritage Exteriors handles the permit process and inspections for you.
Most complete re-side projects run between $18,000 and $35,000, though large custom estates on Los Altos Hills’ one-acre lots can fall at or above the upper end due to greater wall area and architectural detail. We provide a firm, itemized quote after an on-site evaluation of your home’s size, materials, and site conditions.
Absolutely. Many Los Altos Hills homes face long hours of afternoon sun on west and south exposures, driving up cooling loads. Energy-efficient dual-pane windows with low-E coatings reduce solar heat gain and heat loss, improve comfort during the region’s day-to-night temperature swings, and help satisfy Title 24 requirements.
Along with Los Altos Hills, we serve neighboring Santa Clara and San Mateo County communities including Los Altos, Palo Alto, Mountain View, Cupertino, Saratoga, Portola Valley, and Menlo Park. Many share the same foothill fire exposure and climate, so our fire-resistant siding and energy-efficient window solutions apply throughout the Peninsula.
