Tucked into the heart of Santa Clara County at the base of the Santa Cruz foothills, Los Altos enjoys a mild Mediterranean climate—warm, dry summers, cool wet winters, and marine-layer fog that drifts in from the San Francisco Bay. That combination of morning moisture, coastal humidity, and strong afternoon sun is hard on exterior finishes: wood siding cups and rots, paint fades, and trim traps moisture along shaded north-facing walls. Los Altos is known for its leafy neighborhoods and a rich mix of home styles, from mid-century ranches and Eichlers to Spanish Revival, Craftsman bungalows, and newer custom estates, and each one relies on a tight, well-sealed exterior envelope to stay comfortable and protect its value.
Heritage Exteriors specializes in fiber cement siding, including James Hardie products engineered to resist the Bay Area’s moisture, fog, and UV exposure without warping, rotting, or feeding termites. Because Los Altos borders the wildland-urban interface near Los Altos Hills and the foothills, non-combustible fiber cement also adds a valuable layer of fire resistance. We pair that durable siding with energy-efficient, dual-pane replacement windows that cut heat gain during hot inland afternoons, keep interiors comfortable through cool foggy mornings, and help lower utility bills—a smart upgrade for Los Altos’ premium housing stock.

Many prudent Los Altos 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 discerning tastes and environmental demands of Los Altos.
Fiber cement siding, particularly from industry leader James Hardie, is the premier investment for a Los Altos home. It is exceptionally resilient, non-combustible (an important safety feature), and will not rot or be damaged by pests. Its advanced ColorPlus™ Technology finishes are baked-on and engineered to resist fading from intense UV exposure, ensuring your home looks beautiful for years with minimal maintenance, a perfect fit for the local climate.
For homeowners seeking a classic, natural aesthetic that complements Los Altos’s leafy environment, we offer both traditional wood siding and advanced engineered wood products like LP SmartSide®. This material is specially manufactured to resist impact and moisture, providing the authentic look of wood with greater durability and lower maintenance requirements.
High-quality vinyl siding can be a practical choice for certain applications. It is affordable, waterproof, and extremely low-maintenance. Modern insulated vinyl siding options can further boost energy efficiency, providing an extra layer of thermal protection against the summer heat.
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, low-maintenance composite 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 installation to effectively manage winter rains and protect your foundation.
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 environment.
This is a primary benefit for a Los Altos home. 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, attractive, and energy-efficient exterior adds significant value and makes a powerful statement.
Upgrading to well-sealed siding and modern windows with high acoustic ratings can substantially decrease the amount of outside noise entering your home. This enhances the tranquil, semi-rural feel of your Los Altos property, creating a more peaceful indoor environment.
New siding and windows protect your home’s structure from the elements, including winter rains and the effects of summer sun. Materials like fiber cement and fiberglass are exceptionally durable and resistant to pests, rot, and warping, ensuring your home’s exterior remains beautiful and protected for decades to come.

To combat Los Altos’s warm, sunny days, the best windows are those with a low Solar Heat Gain Coefficient (SHGC). We strongly recommend ENERGY STAR® rated windows with advanced Low-E coatings to reflect solar heat. Fiberglass frames are an excellent choice due to their thermal stability and strength, making them ideal for large window openings.
Yes, absolutely. We have extensive experience preparing and submitting project plans for the City of Los Altos’s design review process. We understand the city’s stringent aesthetic guidelines and R1 zoning considerations, and we will work with you to create a plan that meets all requirements for a smooth approval.
For homes in shaded areas, moisture resistance is key. Siding materials like James Hardie fiber cement are ideal as they are impervious to rot and mold. Proper installation of a weather-resistive barrier is also critical to protect the home’s structure from moisture that can be trapped in shady spots.
We provide a comprehensive workmanship warranty on every installation, guaranteeing the quality and longevity of our labor. In addition, you will be covered by extensive manufacturer warranties on the premium products we use, such as the 30-year limited warranty offered on most James Hardie siding products and robust warranties on windows from leading brands. All warranty information will be clearly detailed in your project proposal.
For maximum fade resistance under the intense California sun, we recommend James Hardie products with their factory-applied ColorPlus™ Technology. This multi-coat, baked-on finish is specifically engineered to resist UV damage and remain vibrant for many years, far outlasting a standard paint job and reducing long-term maintenance.

The valley floor of Los Altos is relatively low-risk, but the western edge near Los Altos Hills and the Santa Cruz foothills sits in or near the wildland-urban interface. Non-combustible fiber cement siding like James Hardie is an excellent choice for added fire resistance, and it can help satisfy stricter exterior requirements in hillside areas. We can advise on materials appropriate to your specific location.
Marine-layer fog and winter rain keep many Los Altos walls damp for long stretches, especially on shaded sides, which accelerates rot and paint failure on wood siding. Fiber cement resists that moisture and won’t swell or feed termites. Dual-pane energy-efficient windows also manage the swing between cool foggy mornings and warm, sunny afternoons.
Yes, exterior work like re-siding and window replacement typically requires a permit from the City of Los Altos Building Division, and hillside or historic properties may face additional design review. Heritage Exteriors handles the permitting process and ensures work meets Santa Clara County and California code, including Title 24 energy standards.
Most full re-siding projects fall in the $16,000 to $30,000 range, though the final figure depends on your home’s size, existing wall condition, chosen material, and architectural details. Los Altos homes often feature custom trim, multiple stories, or unique styles like Eichlers that affect scope. We provide a detailed, no-obligation estimate for your specific project.
Los Altos has many mid-century ranches and Eichler homes with clean lines and specific proportions. Fiber cement siding comes in smooth and grooved panel profiles that can honor that mid-century look while dramatically improving durability and moisture resistance over the original wood or hardboard. We match profiles and colors to preserve your home’s character.
Yes. Energy-efficient dual-pane windows reduce heat gain during hot Silicon Valley afternoons and limit heat loss on cool, foggy mornings, easing the load on your heating and cooling. They also help your home meet California’s Title 24 energy requirements. Given Los Altos’ premium home values, the comfort and efficiency gains are a strong long-term investment.
