Window Replacement in San Rafael, CA

Two reasons, one re-side

On San Rafael hillsides we integrate openings into the non-combustible assembly and close ember paths; in the moisture-dominant flats we flash openings into the drying plane correctly. Doing windows with the re-side is what makes either possible to do properly.

Comfort, quiet, and historic proportions

Gains are mostly comfort and noise in the mild climate; on historic downtown San Rafael homes, doing windows with the re-side also preserves original proportions and trim.

Downtown's historic sash and the cost of getting it wrong

The pre-war homes around downtown San Rafael and the older blocks near Fourth Street were built with true divided-light sash and slim, proportioned frames that newer stock windows tend to fight. Drop in a bulky vinyl unit with fat meeting rails and a circa-1920s facade reads as remodeled in the wrong way, which matters on a street where the next house still wears its original profiles. The fix on these parcels is to match sightlines: narrow frames, simulated divided lights where the muntin pattern is part of the architecture, and a flange detail that tucks behind the existing trim rather than swallowing it. Old rough openings are rarely square here, and plaster-keyed interior returns mean a clean swap usually requires careful jamb work, not a pry-and-pop. We size each opening individually instead of ordering a single repeating unit, because two windows that look identical from the sidewalk are often a half-inch apart once the casing comes off. Done right, the home keeps its downtown character and finally seals against the damp.

Wooded hillside lots, tight access, and the ember-rated opening

Getting new windows into the Sun Valley, Gerstle Park, and Dominican-area hillsides is as much a logistics problem as a product choice. These are narrow, switchbacked streets with steep driveways and homes set above or below grade, so large fixed panes and oversized picture units often have to be carried by hand up exterior stairs rather than craned, which shapes what sizes are even practical to specify. The wildfire exposure on these wooded slopes also drives the glazing itself: openings facing downslope vegetation are a documented ignition path, so we lean toward dual-pane assemblies with at least one tempered light and metal-clad or non-combustible frames, integrated with the surrounding wall so an ember landing in the surround finds nothing to catch. Vents and weep paths get screened to the same standard. Because access is constrained, we stage deliveries to match the re-side sequence rather than dropping a full house of units at once on a lot with nowhere to store them, keeping the slope clear and the work moving wall by wall.
