Anlin makes its windows in Clovis, in the heart of the Central Valley, where the summers run every bit as hot as the ones around Clear Lake. That single fact is why the brand is worth a look for a Lake County home: the company designs for a hot inland California climate as its baseline, not as an afterthought, so a lot of what a lake-area homeowner actually needs from a window is already engineered in. Anlin builds energy-focused vinyl replacement windows, and Bay Area Siding Company installs them across the City of Clearlake and the surrounding communities.

A California window for a hot-summer home

The main job a window does around Clear Lake is keep the summer sun's heat outside. Summers here are long and high in UV off California's largest natural lake, and on the south- and west-facing walls that take the brunt of the afternoon, the number that matters most is often the solar heat gain coefficient — how much of the sun's heat the glass lets through. Anlin builds its vinyl units around energy performance, with insulated dual-pane glass and Low-E coatings aimed squarely at cutting that solar gain. Because the company engineers for Central Valley heat, its glass packages tend to line up well with what a hot-summer lake home needs, and we match the coating and package to how much sun each opening really takes.

We also spec every unit to California's Title 24 energy code. Because the required U-factor and solar-heat-gain values shift with the climate zone and the code cycle in force, we confirm the current numbers for your address at permit time rather than quote a figure that may be out of date.

The lines, and the warranty that stands out

• Catalina and Del Mar are Anlin's core replacement lines. They differ in glass options, hardware, and detailing, and we'll match the line to your budget and performance goals rather than default to one.
• The warranty is a genuine reason people choose Anlin. The company markets a strong limited-lifetime warranty that includes glass-breakage coverage — worth having on any home, and especially reassuring on the exposures this region sees. The exact terms are Anlin's to set, so we confirm the current coverage for your order instead of paraphrasing it here.
• Built for retrofit. Anlin's lines are designed for replacing windows in existing homes, which is most of the work on Clear Lake's older housing stock.

Windows and the fire zones

Lake County's wildfire history is serious, and for windows that connects to the building code through Chapter 7A — but only on the parcels it's mapped to. Cal Fire's 2025 maps expanded the very-high fire-hazard zones across much of the county. Where a parcel is designated and the work counts as altering or adding an opening, Chapter 7A generally calls for multi-pane glazing with at least one tempered pane — a requirement that attaches to specific openings, not the whole house as a blanket rule. Whether it applies to your project turns on your parcel's designation and your scope, so we confirm it with the City of Clearlake or the Lake County Community Development Department before ordering glass. Anlin units can be specified with tempered glazing where it's required.

How Anlin compares

Anlin is a vinyl window, so the natural comparisons are other vinyl and fiberglass lines. For a broadly available West-Coast vinyl or a fiberglass option, look at Milgard; for premium composite and clad-wood, Andersen and Marvin; for a range that spans mid to premium, Pella. The window replacement hub frames the whole decision. Anlin's strong suit is the combination of value, a hot-climate energy focus, and that glass-breakage warranty on a straightforward vinyl replacement.

Retrofit or full-frame install

Most Anlin jobs are retrofit (insert) installs — the existing frame stays and the new unit sets into it, which is quicker and less invasive and a good fit where the frame and surrounding wall are sound. Where there's rot, prior water intrusion, or siding coming off at the same time, a new-construction (full-frame) install removes the window to the rough opening so the flashing and the water-resistive barrier at the opening can be fully renewed. We tell you which your openings need after we look, not before.

What drives the cost

We quote after seeing the openings. Drivers: the number and size of windows; the Anlin line and glass package; retrofit versus full-frame; whether fire-zone tempered or multi-pane glazing is required on your parcel; the condition of the framing behind the old units (rot repair adds scope); and access on upper-story or hillside openings. Anlin generally offers strong value for a well-warrantied, energy-focused vinyl window.

FAQ

Are Anlin windows a good fit for Clear Lake's heat? Yes — that's a real strength. Anlin is made in Clovis for a hot inland California climate, and its Low-E glass packages are built to cut solar heat gain, which is the main thing a window does on a lake home in summer. We tune the glass to your exposures and to current Title 24.

What does the Anlin warranty cover? Anlin markets a strong limited-lifetime warranty that includes glass-breakage coverage. The exact terms are set by Anlin; we confirm the current coverage for your order rather than paraphrase it.

Will Anlin meet the fire-zone glass rules if my parcel needs them? Where Chapter 7A applies, altered or new openings generally need multi-pane glazing with at least one tempered pane, which Anlin units can be specified to meet. Whether your parcel is designated is confirmed with the City of Clearlake or Lake County before we order.

Do I need a permit to replace my windows? Yes — window replacement is permitted work and includes a Title 24 energy compliance form. It's handled through the City of Clearlake Building Department in the city, or the Lake County Community Development Department on unincorporated parcels. We take care of it.
