San Anselmo homes aren’t a one-size-fits-all job. The housing stock runs from 1920s bungalows with single-pane wood sashes to mid-century ranchers and newer builds, each with its own rough opening quirks. Our Window Replacement team knows what’s behind those walls before the first screw comes out.

Why Juniper Windows & Doors Is San Anselmo’s Preferred Window Replacement Company

We’ve worked in enough San Anselmo homes to know the difference between a clean swap and a job that’s hiding rot behind the jamb. Older frames near Red Hill and Sleepy Hollow often have settled out of square, and a stock-size unit won’t sit flush no matter how carefully it’s trimmed. That’s why we field-measure every opening before ordering anything. Sean Mackey runs our scoping process, and he insists the number on the written quote is the number on the final invoice.

San Anselmo homeowners call us because the estimate doesn’t morph into a surprise. Every project gets a written price before work starts, backed by the 365-Day Done Right Promise in writing. If the install isn’t right, we fix it, parts and labor, for a full year. The crews are background-checked, uniformed, and they arrive with a live arrival time you can track from your phone.

Response time to San Anselmo is typically same-week for measurements and one to three days on site once your windows are in hand. We coordinate scheduling from our San Francisco Bay Area office, and the people who answer the phone at 24/7 are real humans, not a voicemail tree.

Window Glass Replacement in San Anselmo

Window Glass Replacement in San Anselmo is the right call when the frame is structurally sound but the glass itself is failed. In older San Anselmo homes, that usually shows up as fog between panes, a crack from a branch or a baseball, or a single-pane sash that’s bleeding heat into the cool creek-adjacent evenings. Replacing just the glass costs $200 to $700 per sash depending on the glass package and whether we’re working with the existing frame or rebuilding the glazing stops.

When the Frame Is Fine But the Glass Is Gone

We see this a lot in the bungalows along San Anselmo Avenue. The original double-hung frame is square, the sashes still travel, but the single-pane glass offers nothing for noise or heat loss. We can cut a new insulated glass unit to fit the existing sash, which keeps the look and stops the draft without touching the trim.

Upgrading to Low-E Without Replacing the Window

If you want better comfort without a full swap, low-E glass drops U-factor noticeably, and it’s a half-day job per sash. That matters in San Anselmo, where summer sun hits west-facing rooms hard and winter mornings sit in the 40s. Expect $350 to $600 per sash for a standard double-strength low-E unit.

Window Sash Replacement in San Anselmo

Window Sash Replacement in San Anselmo means swapping the movable panel that holds the glass while keeping the existing frame in the wall. It works well when the frame is plumb and solid but the sash itself has warped, rotted, or lost its seal. In San Anselmo’s older hillside homes, this is common, because decades of damp winters and dry summers push wood sashes out of square. Replacing a sash runs $300 to $800 per opening, and it’s a cleaner, faster job than a full-frame replacement.

What a Sash Swap Actually Fixes

A sash replacement stops drafts from a warped panel, seals failed insulated glass, and restores smooth travel on worn hardware. We match the stile width and rail profile to the existing frame so the window still looks like the house. For homes in the downtown historic zone, that matters.

Sash Replacement vs. Full Frame Replacement

If the jamb itself is rotted or the rough opening is out of square, a sash-only job won’t hold. We inspect the sill, the side jambs, and the header before recommending anything. If the frame is sound, a sash swap saves real money. If it isn’t, we’ll tell you before you spend a dime on materials.

Trusted Brands We Service in San Anselmo

Juniper Windows & Doors installs and services eight product lines, and we keep local stock for the brands San Anselmo homeowners already have: CGI, CWS, and ECO Window Systems. If you have a failed insulated unit in a CGI frame or a CWS sash that’s binding, we can source the replacement parts without waiting on a cross-country shipment. The right window is never a compromise, and when a specific brand already matches your home’s trim and sightlines, we’d rather service it correctly than push you into a different product. Our team also regularly works with ES Windows for homes that need a narrower frame profile.

Common Window Replacement Problems We See in San Anselmo Homes

• Out-of-square rough openings. Older hillside bungalows settle, and a jamb that was true in 1932 isn’t true today. We field-measure every opening before ordering.
• Rot hidden behind the old frame. Moisture off the creeks and decades of fog creep into wood sills and side jambs. It only shows once the old sash is out, so we price for inspection, not assumption.
• Single-pane sashes that don’t seal. Wood expands and contracts through Marin’s wet-dry cycles. By the time a double-hung won’t lock, the sash has usually cupped or pulled at the corners.
• Design review on exterior changes. San Anselmo’s downtown and hillside neighborhoods have real scrutiny on visible trim, color, and sash profiles. We check the review requirements before ordering anything you’d have to change.
