Livermore Window Replacement provides professional bay and bow window assemblies in Livermore, CA for residential and commercial properties across the Tri-Valley. A bay or a bow is barely a window. It is a small piece of structure that hangs off the wall, carries its own roof, and presents several more feet of joint to the weather than the flat opening it replaced.
That is the thing to understand before you buy one here. A projecting assembly sits further out into moving air than the wall plane does, and it has head, sill, seat board and mullion joints that a flat window simply does not have. Every one of those joints is a place a steady pressure differential can find, so the build quality of the assembly matters more than the glass in it.
Our standard specification for this town is a fixed center panel with casement flankers rather than double-hung or slider flankers. The flanking units are where the ventilation and the leakage both live, and putting crank sashes at the angled returns means the two most exposed elements in the assembly are the two that tighten under pressure. It is a small specification change with an outsized effect.
Support is the second thing we look at. A bay needs either knee braces under the seat board or cable support from the header above, sized to the projection and the weight of the glass. Sagging shows up first as a seat board that no longer sits level and then as sash that will not latch, and by that point the seals have already been working crooked for a year.
The roof over the projection deserves real flashing rather than a bead of sealant. We want a step-flashed or fully soldered head condition tied into the wall's weather barrier, with a proper kickout where the roof meets the siding. This is the single most common defect we find on bays built in the 1980s tracts around town.
Insulate the seat board and the underside. Those two surfaces are often the only part of a bay that faces the outdoors on three sides, and in an unheated cavity they turn the window seat into the coldest spot in the room every January. Rigid foam under the deck and a properly sealed cavity fixes it once.
Bow assemblies, with four to six units in a gentle radius, spread the same problem across more mullions. They look better on a wide traditional facade and they are more work to make tight. We build them with fixed panels at the ends and operable units in the middle, which keeps the hardest joints out of the corners.
If the goal is just more light in a room and you are not attached to the projection, a wide fixed panel with a casement at each end costs less, seals better and needs no roof. We suggest that often enough that it is worth mentioning before anybody falls in love with a drawing.
Our insured and bonded team brings the right materials and equipment to every job — compression-set casement weatherstripping, brush pile weatherstrip in a slider track, multipoint locking hardware on a casement sash, an air leakage rating measured at 75 pascals, co-extruded bulb gasket at the sash perimeter, low-conductance warm-edge spacer — and backs the work with a written workmanship warranty. We serve Livermore and nearby communities including Dublin, San Ramon, Danville, Alamo.

Materials, equipment and how we do bay and bow window assemblies
The difference between bay and bow window assemblies that lasts and bay and bow window assemblies that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with compression-set casement weatherstripping, brush pile weatherstrip in a slider track, multipoint locking hardware on a casement sash, an air leakage rating measured at 75 pascals, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Livermore job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of window work in the Tri-Valley means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Livermore Chooses Livermore Window Replacement
- ✓We specify by elevation rather than by house, because a wall facing the pass and a wall behind the garage are two different problems and should not get the same window.
- ✓The published air-leakage figure, in cfm per square foot of window area, goes on the proposal beside the price, so you can see what you are buying instead of taking our word for it.
- ✓We quote two operating types on every exposed opening and tell you in writing when the cheaper one is the right call for that wall.
- ✓We will talk you out of an impact or design-pressure package on wind grounds, because that rating measures storm survival and it is not the failure this valley produces.
