Looking for a reliable contractor in Santa Clara? Hamilton Exteriors provides full-service design-build construction for homeowners across Santa Clara. From roofing and siding to ADUs and custom homes, we handle every project with an architect's eye and a builder's precision.
Why Santa Clara Homeowners Choose Hamilton Exteriors
Santa Clara's housing stock ranges from Eichler mid-century homes in the central neighborhoods to newer custom builds near the foothills. Each comes with its own set of challenges. As an architect-led firm, we evaluate your home as a complete system, not just a list of repairs.
Our founder, Alex Hamilton Li, is both a licensed architect and a general contractor (CSLB #1078806). This dual credential means we design and build with a unified vision, catching coordination issues before they become costly change orders. Most Santa Clara contractors are tradesmen-only; we bring architectural thinking to every project.
Our Services in Santa Clara
Roofing
Santa Clara's hot summers push roofing materials to their limits. Temperatures regularly exceed 95 degrees, and the UV exposure accelerates granule loss on standard shingles. We install GAF, CertainTeed, and Owens Corning systems with proper attic ventilation to extend roof life.
Typical asphalt shingle replacement on a 2,000 sq ft Santa Clara home runs $19,500 to $24,000, including tear-off, synthetic underlayment, flashing, and permit fees. Tile roofs, common in older Santa Clara neighborhoods, cost $35,000 to $55,000 for the same size home. See our roofing services page for details.
Siding
Santa Clara's climate is relatively dry, but the summer sun can fade and crack wood siding over time. James Hardie fiber cement siding resists heat, moisture, and pests while maintaining a clean appearance. We are a James Hardie Elite Preferred Contractor, the highest certification level.
Windows
Older Santa Clara homes often have single-pane windows that leak conditioned air. Energy-efficient replacements reduce cooling costs during the summer months and improve home comfort. We install windows from major manufacturers with proper flashing and insulation.
ADU Construction
Santa Clara's ADU ordinance allows accessory dwelling units on most single-family lots. Whether you are building a detached backyard cottage or converting an existing garage, we handle design, permitting, and construction. Our ADU services include everything from foundation to finish.
Home Additions
Adding square footage to a Santa Clara home requires careful planning around setback requirements, height limits, and structural connections. We design additions that blend seamlessly with the existing architecture. Explore our home addition services.
Custom Homes
For homeowners starting from scratch, we offer full custom home construction. From site planning through final inspection, we manage every trade and coordinate with city inspectors. See our custom home portfolio.
Santa Clara Building Permits and Codes
Every construction project in Santa Clara requires a building permit from the Santa Clara Permitting Division. Permit fees vary by project scope:
- Roof replacement: $400 to $800
- Window replacement: $100 to $300 per window
- ADU: $2,000 to $5,000
- Home addition: $1,500 to $4,000
We pull all permits on your behalf and schedule the required inspections. The permit process protects you by ensuring code compliance, which matters at resale.
Fire Risk and Building in Santa Clara
While Santa Clara itself is not in a designated Wildland-Urban Interface zone, the nearby foothills in Saratoga, Los Gatos, and parts of Cupertino are classified as Very High Fire Hazard Severity Zones by CAL FIRE. Homes in those areas require Class A fire-rated roofing materials, ember-resistant vents, and defensible space compliance.
If your Santa Clara property borders open space or has significant vegetation, we recommend upgrading to Class A materials even if not required. The cost difference is modest compared to the peace of mind.
Seismic Considerations
Santa Clara County sits near three major fault systems: the San Andreas, Calaveras, and Hayward faults. Parts of Santa Clara are in mapped liquefaction zones, particularly areas with alluvial soils near the Guadalupe River. For major projects like additions or ADUs, we incorporate seismic bracing and foundation upgrades as needed.
