Why Novato Homeowners Choose Hamilton Exteriors
Novato's climate and building conditions are different from coastal Marin. Inland Novato is drier and warmer than Mill Valley or Larkspur, which means windows face more thermal expansion and UV exposure over time. Our architect-led approach accounts for these local factors in every installation.
Architect-led design-build. Unlike most window contractors, Hamilton Exteriors is led by Alex Hamilton Li, a licensed architect and general contractor (CSLB #1078806). This means we evaluate your windows as part of your home's whole building system — considering ventilation, energy performance, and aesthetics together.
Factory-trained installers. Every crew member is manufacturer-certified in Milgard, Andersen, and Marvin window systems. We don't subcontract window installations.
50-year warranty. We back every window installation with a 50-year manufacturer warranty plus our own workmanship guarantee for the full duration.
Transparent pricing. Every estimate is itemized line by line — window units, trim, flashing, labor, permit fees, and cleanup listed separately.

Window Styles for Novato Homes
Novato's housing stock spans mid-century ranches, contemporary custom homes, and newer subdivisions. Each style benefits from different window types.
Double Hung Windows
The most versatile choice for Novato homes. Double hung windows have two operable sashes that tilt in for easy cleaning. They work well in traditional and contemporary homes alike. U-factors as low as 0.27 exceed California Title 24 energy requirements by 15 to 20 percent ENERGY STAR.
Casement Windows
Crank-open casement windows capture 50 to 90 percent more airflow than sliders and seal tighter than any other operable window AAMA. They are ideal for Novato homes that rely on natural cooling instead of air conditioning.
Picture Windows
Large fixed-pane windows that maximize natural light and frame views of Mount Burdell or the Novato hills. The most energy-efficient window type available, with U-factors as low as 0.20.
Sliding Windows
Horizontal sliders work well in mid-century modern and Eichler-style homes common in Novato's Hamilton neighborhood. They require no exterior clearance and are easy to operate.
Novato Building Permits for Window Replacement
Most window replacements in Novato require a building permit from the City of Novato Community Development Department. Permit fees typically range from $200 to $600 depending on the scope of work. Hamilton Exteriors handles the entire permit process — application, plan submission, and scheduling inspections. Permit fees appear as a separate line item in your estimate so you see every cost upfront.
Fire Zone Considerations in Novato
Much of Marin County, including parts of Novato, is designated as a Wildland-Urban Interface (WUI) High or Very High Fire Hazard Severity Zone CAL FIRE. While window replacement itself does not trigger Chapter 7A requirements, if you are replacing windows in a WUI zone, we ensure proper ember-resistant installation methods. This includes non-combustible flashing and proper sealing around window frames to prevent ember intrusion.
Seismic Considerations for Window Installation
Marin County sits near the western edge of the San Andreas Fault. Most of Marin, including Novato, is in a moderate seismic zone USGS. During window replacement, we ensure proper anchoring and shimming to meet seismic code requirements. Older Novato homes with original aluminum windows often need structural reinforcement around rough openings — we assess this during the initial inspection.
Energy Efficiency and Savings
ENERGY STAR certified windows can save Novato homeowners $125 to $465 per year on energy bills U.S. Department of Energy. Novato's inland climate means homes experience more temperature variation than coastal Marin, making energy-efficient windows particularly valuable. Hamilton Exteriors installs windows with U-factors as low as 0.25, exceeding California Title 24 requirements.
