Anlin is the window we point Larkspur homeowners toward when the goal is a genuinely energy-efficient, well-warranted vinyl replacement without stepping into premium-wood pricing. It's built in Clovis, in California's Central Valley, and engineered around West Coast climates and the state's energy code — a natural match for the comfort-and-efficiency upgrade most homes in this damp, marine-influenced town are after. Bay Area Siding Company is based a few blocks over on Magnolia Avenue and installs Anlin across Larkspur, from the old cottages near downtown to the canyon and hillside houses up toward King Mountain. We run the whole job: measuring, glazing selection, permitting, removal, flashing, air-sealing, and the walkthrough.

What sets Anlin apart

Most vinyl windows are a commodity. Anlin positions itself a notch above — a value-premium vinyl that leans on three things:

• Made in California, for California. Anlin builds in Clovis and designs its glass packages around West Coast conditions and the state's energy code. For a Larkspur home that means the standard product already leans toward the dual-pane, Low-E performance the state expects, rather than a national spec you have to upgrade your way into.
• Energy performance is the whole pitch. Insulated dual-pane glass, Low-E coatings, warm-edge spacers, and multi-chambered frames that cut conduction. In a town where a lot of older houses still run on original single-pane sash and shaded canyon rooms hold the chill, that's the lever that changes how a room feels through a wet winter.
• A warranty built to reassure. Anlin's coverage is one of its calling cards, with limited-lifetime terms and glass-breakage protection among the features it's known for. We state warranty coverage generally and confirm the current terms in writing before you order — but the posture is unusually homeowner-friendly for vinyl.

Anlin's product lines

Anlin keeps its lineup focused, which makes the choice simpler than with the sprawling national brands:

• Catalina — Anlin's flagship line, where most Larkspur replacement projects land when both energy performance and a refined look matter.
• Del Mar — a strong-value line that still carries Anlin's efficiency and warranty character, suited to whole-home changeouts where budget discipline matters across a lot of openings.

Both are vinyl, both come in a range of operating styles — sliders, single- and double-hung, casements, picture units — and both can be specified with the glass package your comfort goals and permit call for. On a walkthrough we match the line and glass to the room, the exposure, and the budget.

Who Anlin is right for

Anlin is the sweet spot for a Larkspur homeowner who wants meaningfully better efficiency and a solid warranty, likes the low-maintenance reality of vinyl — no repainting, no rot, which counts near the tidal-damp creek flats — and doesn't need the wood or clad-wood look of a premium brand. If your priority is architectural authenticity on an older home near the Magnolia Avenue historic district, a clad-wood option like Marvin or Andersen may suit the aesthetic better; if you want the broadest West Coast availability across materials, compare Milgard; for a national brand spanning vinyl through wood, see Pella. Start from our window replacement hub if you're still weighing brands.

The Larkspur angle: energy first, glazing where the parcel calls for it

In Larkspur's mild, marine-influenced climate, the value of a good window is less about fighting extreme heat than about killing drafts and holding warmth through damp winters — exactly where Anlin's efficiency story lands cleanly. California's Title 24 energy code caps U-factor and SHGC for replacement windows, and the required numbers shift by climate zone and code cycle, so we spec to the code in effect at permit time rather than to a figure quoted online, and the City of Larkspur takes the Title 24 documentation with the submittal.

One local wrinkle: Larkspur's canyon and hillside neighborhoods carry real wildfire exposure, and Central Marin Fire adopted California's updated Fire Hazard Severity Zone maps in 2025. Where an opening is altered on a parcel in a High or Very High zone or the Wildland-Urban Interface, California Building Code Chapter 7A can require exterior glazing to be multi-pane with at least one tempered pane. Whether that applies depends on your specific parcel and whether the work is a repair or an alteration — Anlin windows can be built with tempered glazing to suit, and we confirm the requirement with the City and Central Marin Fire before ordering. Larkspur requires a building permit for window replacement either way; we handle the paperwork.

What affects the cost

We don't post prices, because every job is different. With Anlin the drivers are the number and size of openings, the line (Catalina vs. Del Mar) and glass package you choose, retrofit versus new-construction method, whether a canyon parcel triggers tempered or multi-pane glazing, the condition of the existing framing (rot repair adds scope, common in this damp climate), and access on a hillside or upper story. A retrofit (insert) install keeps your existing frame and is less invasive; a new-construction install removes the window to the framing so flashing can be fully renewed — the right call where there's rot or past water intrusion. We do both and recommend based on what we find.

Frequently asked questions

Is Anlin really made in California? Yes — Anlin manufactures its windows in Clovis, California. For Larkspur homeowners that means a product engineered around West Coast climates and the state's energy code rather than a generic national spec.

Can Anlin windows meet Larkspur's fire-zone glazing rules on a canyon lot? Yes. On a canyon or hillside 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 whether the work is a repair or an alteration, which we confirm with the City and Central Marin Fire before ordering.

How does Anlin compare to Milgard? Both are widely installed West Coast vinyl. Anlin leans harder on energy performance and warranty as its identity and is made in California; Milgard offers a broader material range including fiberglass and enormous availability. On a walkthrough we'll tell you which fits your openings and budget better.

Do I need a permit for Anlin windows in Larkspur? Yes. The City of Larkspur requires a building permit for window replacement, with Title 24 energy documentation in the submittal. We prepare and file it.
