Window Replacement in Larkspur, CA

Different reason per Larkspur, one re-side

On Magnolia-area homes we preserve period proportions; on bayside/canyon homes we flash openings into the drying-capable plane against high moisture; on the wooded hillside we also integrate them into the hardened assembly. Doing windows with the re-side is what makes each possible.

Comfort in a cool, shaded climate

Gains are comfort and moisture/condensation control rather than big energy savings in the cool shaded climate; the largest come when flashing and air-sealing are corrected during the re-side.

Fitting new windows to Baltimore Canyon and ferry-side lots

Larkspur's housing splits into terrain you can feel from the street, and window replacement has to answer the lot it sits on. Up in redwood-shaded Baltimore Canyon, hillside homes are reached by narrow, steep lanes where staging a crew, a dumpster, and large glass units takes planning long before the first sash comes out; oversized fixed panes often have to be carried in by hand rather than craned. Down toward the ferry and the bayside flats, the ground is softer and damper, so we watch sill conditions and water tables that the canyon homes never see. Downtown around Magnolia, the older stock carries narrow, tall openings and divided-light proportions that a stock vinyl insert quietly erases. Matching sightlines there usually means a full-frame unit sized to the original rough opening rather than a pocket retrofit. Knowing which of these three Larkspur situations you are in decides the window line, the install method, and how much of the surrounding wall has to be opened to do it correctly the first time.

One opening, two jobs: drying detail plus an ignition-resistant edge

What makes window work in Larkspur unusual is that a single opening has to solve two problems at once. Persistent North Bay damp, fed by canyon shade and bay air, wants every head, jamb, and sill flashed so water that gets behind the trim can drain and dry instead of soaking the framing. At the same time, the wooded Baltimore Canyon slopes sit in a real wildfire consideration, which pushes the same opening toward dual-pane tempered glass, non-combustible or fire-rated framing where exposure warrants, and sealed gaps that embers cannot exploit. Those two goals can fight each other if you only chase one, which is why we treat the window as part of the wall rather than a drop-in part. The cleanest result comes when the cladding is off and the opening can be flashed into a drying plane and tied into a hardened edge in the same pass. Trying to upgrade glass for fire while leaving an old, leak-prone flashing detail in place tends to trade one Larkspur risk for the other.
