For a Belmont homeowner who wants a real efficiency upgrade and a warranty they can lean on — but doesn't want to pay for premium wood windows — Anlin is usually the window we point to. It's vinyl, but it sits a clear step above commodity vinyl: made in Clovis, California, and engineered specifically around West Coast climates and the state's energy code. Bay Area Siding Company installs Anlin throughout Belmont, from the ranch homes near Carlmont to the custom houses up the western slope, and we run the complete job — measure, glazing, permit, removal, flashing, air-seal, and walkthrough.

The California-made advantage

Anlin's whole identity is being built for exactly the conditions a Belmont home faces. Because it's manufactured in-state and designed around California's energy rules, the standard product already ships oriented toward the dual-pane, Low-E performance the state expects — you're not upgrading a national baseline spec up to code, you're starting there. For a house in Belmont's mild, coastal-influenced climate (California Energy Code Climate Zone 3), where the real enemy is drafts and heat loss through damp winters rather than brutal summer sun, that efficiency-first design lands cleanly.

Two lines, kept simple

Anlin doesn't sprawl the way some national brands do, which makes choosing easier:

• Catalina — the flagship, and where most Belmont projects land when energy performance and a refined appearance both matter.
• Del Mar — a strong-value line that keeps Anlin's efficiency and warranty character, well-suited to whole-home changeouts where you're replacing a lot of openings and watching the budget.

Both come in the usual operating styles — single- and double-hung, sliders, casements, and picture units — and both can be built with the glass package your comfort goals and permit call for.

The warranty question

Warranty is a big part of why homeowners choose Anlin. The brand is known for homeowner-friendly coverage, with limited-lifetime terms and glass-breakage protection among its features. We state coverage generally and confirm the current written terms before you order rather than quoting numbers from memory — but for a vinyl window, the posture is unusually reassuring, and on a whole-home project that peace of mind carries weight.

Where Anlin fits — and where it might not

Anlin is the sweet spot for a homeowner who wants meaningfully better efficiency, likes vinyl's no-repaint, no-rot reality, and doesn't need a wood or clad-wood look. If your priority is architectural authenticity on a period or high-design Belmont home, a clad-wood option like Marvin or Andersen may suit the aesthetic better. If you want the broadest West Coast material range, compare Milgard; for a national brand spanning vinyl through wood, see Pella. Still weighing brands? Start at the window replacement hub.

Belmont permits and the hillside glazing question

Belmont requires a permit for window replacement, and because a window swap is an alteration under the Energy Code, Title 24 documentation is part of the submittal — the City of Belmont Building Department (Permit Center) reviews it, and we handle the paperwork.

There's also a fire-zone factor if your home is up in the wooded western hills. Those slopes fall within fire hazard severity zones on Cal Fire's 2025 Local Responsibility Area maps, in the area served by San Mateo Consolidated Fire. Where an opening in a mapped fire-hazard area is altered, California Building Code Chapter 7A can require multi-pane glazing with at least one tempered pane. Anlin units can be built with tempered glazing to suit, and whether the requirement applies to your parcel depends on its designation and whether the work is classed as repair or alteration — we confirm it with the City before ordering. Homes down in flatter East Belmont generally don't carry this glazing concern.

What affects the cost

We don't post prices, because every job differs. With Anlin the drivers are the number and size of openings; the line (Catalina or Del Mar) and glass package; retrofit versus new-construction method; whether a hillside parcel triggers tempered or multi-pane glazing; the condition of the existing framing, since rot repair adds scope; and access on an upper story or a hillside lot. A retrofit keeps the existing frame and is less invasive; a new-construction install takes the window back to the framing so flashing can be fully renewed — the right call where there's rot or past water intrusion.

FAQ

Is Anlin actually made in California? Yes — Anlin builds its windows in Clovis, in the Central Valley. For a Belmont home that means a product designed around West Coast climate and the state's energy code, not a generic national spec.

Can Anlin meet Belmont's hillside fire-zone glazing rules? Yes. On a mapped western-hills parcel where an altered opening triggers Chapter 7A, Anlin units can be ordered with multi-pane, tempered glazing. Whether your parcel requires it depends on its designation and scope, which we confirm with the City before ordering.

How does Anlin compare to Milgard? Both are widely installed West Coast vinyl. Anlin leans hardest on energy performance and warranty and is California-made; Milgard offers a broader material range including fiberglass and very wide availability. We'll tell you which fits your openings and budget on a walkthrough.

Do I need a permit for Anlin windows in Belmont? Yes. Belmont's Building Department reviews window replacement, with Title 24 energy documentation part of the submittal. We prepare and file it.
