Window Company in Larkfield-Wikiup, CA
Juniper Windows & Doors is the window company Larkfield-Wikiup homeowners call when fogged glass, warped sashes, and doors that no longer close square stop being a nuisance and start costing money every month. Most homes here were built between the 1970s and early 2000s, which means the original aluminum sliders and hollow-core entry doors have hit the end of their useful life. The combination of warm inland Sonoma County summers and cool, damp winters accelerates seal failure, so we see a lot of glass that looks permanently milky.

Why Larkfield-Wikiup Homes Are Different
Larkfield-Wikiup sits just north of Santa Rosa along the Old Redwood Highway corridor, and the housing stock tells a clear story. The area grew in distinct waves: older ranch-style homes from the 1960s and 1970s with single-pane aluminum windows, then a run of 1980s and 1990s production builds with builder-grade wood frames and sliding patio doors, plus newer custom homes and rebuilds after the 2017 Tubbs Fire changed parts of the neighborhood. That mix matters. We’re often working on a 1972 ranch on Mark West Springs Road in the same week as a 2004 two-story near Wikiup Drive, and each one needs a different approach to flashing, sill condition, and frame squareness.
Climate plays a bigger role than people expect. Larkfield-Wikiup gets real summer heat pushing into the 90s, but the winter mornings bring fog and damp that sits against window frames. Wood frames here rot at the bottom corners first. Aluminum frames sweat and corrode where the salt air from the coast collides with warm interior air. We account for all of it when we spec a replacement, because a window that performs well in Santa Rosa’s flatland microclimate can still underperform up here in the Mark West Creek drainage.
Our Main Larkfield-Wikiup Services
The two jobs Larkfield-Wikiup homeowners call about most are Window Replacement in Larkfield-Wikiup and Door Replacement in Larkfield-Wikiup. Window installation for new construction and additions runs a close third. Here’s what each involves here.
Window Replacement in Larkfield-Wikiup
Replacement means pulling the old sash and frame out of an existing opening and installing a new window that fits without disturbing the surrounding stucco, siding, or interior trim. In Larkfield-Wikiup, the biggest variable is what’s lurking behind the old window. We’ve pulled frames on Mark West Springs Road and found rot running half a stud deep where sprinklers hit the wall for twenty years. Every replacement starts with an inspection of the rough opening, the flashing, and the sill slope, because the new window is only as good as the hole it sits in. Window Replacement in Larkfield-Wikiup gets its own page with full pricing and a detailed look at how we handle rot repair, stucco returns, and retrofitting into older openings.

Window Installation in Larkfield-Wikiup
Installation is for brand-new construction, additions, or wall openings that didn’t have a window before. The framing, flashing, waterproofing, and exterior trim all have to be done in sequence, and in Larkfield-Wikiup that means working around stucco, wood siding, and the occasional HardiePlank. We coordinate with the general contractor when there is one, or handle the full rough-to-trim scope when there isn’t. The standard we build to is the same one the manufacturer’s warranty requires, because a flashing mistake in a new wall shows up as a leak in the first rainy winter. Window Installation in Larkfield-Wikiup covers the full process, from rough opening to final trim.

Door Replacement in Larkfield-Wikiup
Front doors here take direct afternoon sun in the summer and cold, damp air all winter, and the old hollow-core doors common in 1980s Larkfield-Wikiup builds don’t do well with either. We replace entry doors, patio sliders, and French doors, and the same rules apply: rot inspection at the threshold, shimming to true, and weatherstripping that actually seals. A door that’s not square to the jamb wears out hardware fast and leaks conditioned air year-round. We stock Therma-Tru and ViewLux entry systems for the security and thermal side, plus PGT sliders for the view without the heat loss. Door Replacement in Larkfield-Wikiup details what a full replacement includes, from threshold to trim.

What pushes a Larkfield-Wikiup job toward the top of a range is rot repair behind old frames, stucco patching after a retrofit, or a non-standard opening size that requires a custom order. What doesn’t change is the price once it’s written. Every Juniper job gets a line-item quote before any work starts, and that number holds.

Replacing a window or door in the same opening typically does not require a permit in Sonoma County when the rough opening isn’t modified. New openings, structural changes, and some fire-rebuild zones are different, and we tell you exactly which category your job falls into before we start. The permit, when required, gets pulled with the quote attached, so there are no surprises.
No. The price on your written quote is the price you pay, full stop. If we open a wall and find rot that has to be fixed before a window can go in, we show you photos, write a change order with a number, and wait for your approval. But the original quote is the contract, not a suggestion.
