Fast, Reliable Window Replacement Across Berkeley

Older homes with wood sash and historic district requirements land on the higher end.

Why Meridian Windows & Doors Is Berkeley’s Preferred Window Replacement Company
We know Berkeley’s housing stock because we work in it every week. A 1910 brown-shingle bungalow on the flats and a 1960s hillside contemporary need different products, different flashing details, and different paperwork. Our Window Replacement team specs from eight manufacturer lines, so the decision starts with what your house actually needs, not what happens to be in stock. The price goes on paper before any work starts, and it does not move at the door. That is the Garrison Standard, and we have held to it since 2009.
Elliot Vance runs our Berkeley installs and keeps the same discipline on every job: uniformed, background-checked technicians, a written scope, and a call answered by a live person at any hour. We do not rotate crews from out of town. The people who show up are the ones who know the building department’s quirks and the fog patterns west of San Pablo Avenue. Every job is covered in writing by the 365-Day Done Right Promise. If it fails within a year, we come back at no charge.
Window Repair in Berkeley
Window repair in Berkeley often means restoring the existing wood sash rather than pulling the whole unit out, especially on the older Victorians and brown-shingles south of campus. We replace broken glass, rebuild rotted sills, re-glaze dried putty, and re-flash openings that have been leaking for decades. A typical repair runs $180 to $650 depending on whether we are re-glazing a single sash or rebuilding a sill and jamb. Historic district requirements often make repair the smarter move, because replacing the window outright can trigger design review.
Sash and Glass Repair
We pull the sash, route out rotted wood, splice in new stock, and re-glaze with proper glazing compound that actually lasts in Berkeley’s marine-layer moisture. Glass replacement runs $90 to $300 per pane for clear or low-E insulated units.
Flashing and Leak Repair
West Berkeley and the flats get regular fog, and pre-1940 homes often have no sill pan flashing under the windows. We pull the exterior casing where needed, install proper flashing, and re-seal with a joint detail that sheds water instead of trapping it. Leak repairs run $300 to $900 per opening depending on how much rot we uncover.
Window Replacement Company in Berkeley
As a full-service window replacement company in Berkeley, we handle everything from single insert replacements to whole-house frame-out projects, plus our Patio Door Installation in Berkeley. Inserts keep your existing trim and jambs, which often clears the historic review process faster in districts the Landmark Preservation Commission oversees. Full-frame replacement is the right call when the rough opening has rot, the studs need shimming, or you want to change the opening size. Single insert replacements run $850 to $1,900, and full-frame work runs $1,400 to $3,200 per opening, including haul-away.
Insert Window Replacement
For Berkeley homes with sound frames, inserts preserve the original interior trim and exterior casing. The new window slides into the existing jamb, we insulate and seal the perimeter, and the whole job often takes under an hour per opening. This is the most common route in Elmwood and North Berkeley, where wood trim is part of the home’s character.
Full Frame Replacement
When the existing frame is rotted or the opening was never flashed correctly, a full-frame job removes everything down to the rough opening. We rebuild the jamb, install new flashing, and set the new window in a plumb, square opening. Hillside homes in the Berkeley Hills often need this because wind-driven rain has been eating at unflashed sills for decades.

Trusted Brands We Service in Berkeley
We are authorized to install and replace products from ViewLux, PGT, CGI, and CWS, among eight manufacturer lines we keep in the portfolio. For Berkeley hillside exposures, we often spec PGT or CGI impact-rated units. For quiet, energy-efficient inserts on the flats, ViewLux vinyl fits well. Because we are a local shop serving Window Replacement in Berkeley, we can order exact sizes and have units delivered to our Bay Area shop quickly without the big-box supply chain delays.
Common Window Replacement Problems We See in Berkeley Homes
- Historic district compliance: In designated landmarks and districts, Berkeley can require wood-frame profiles and specific divided-light patterns. Ordering a standard white vinyl unit without checking the parcel first means a full reorder and several lost weeks.
- Fog-side water intrusion: Homes west of San Pablo Avenue and in the flats deal with marine-layer humidity that works into unflashed openings. Without sill pan flashing, new windows often leak within the first year because water has no path out.
- Wind-driven rain in the Berkeley Hills: East of Grizzly Peak, design pressures climb fast. A standard unit that works on the flats can fail on a hillside exposure. We calculate design pressure per opening, not per house.
- Old sash rot hidden in trim: Berkeley homes built before 1930 often have hidden rot in the jamb corners where water collected for decades. Full-frame replacement is the only honest fix when the structure is gone, even if the trim looks fine from the street.
Pricing for Window Replacement in Berkeley, CA
Standard vinyl insert replacements in Berkeley run $850 to $1,900 per window installed. Full-frame replacements run $1,400 to $3,200 per opening. Wood-frame windows, especially in historic districts, land at the top of that range or slightly above because the material and labor are heavier. Glass-only repairs run $90 to $300 per pane. Permits, when required, add $200 to $600 depending on the scope and whether a zoning certificate is needed. The price we write down includes the permit cost, haul-away, flashing, and interior trim work unless we flag something else during scope.

FAQs About Window Replacement in Berkeley
If you are replacing windows in kind, meaning same size and same opening, a building permit is typically required but the review is faster than you might expect, usually two to four weeks. If your home is in a designated historic district or on the Landmark Preservation Commission’s list, that timeline can stretch to six or eight weeks while design review runs. We pull the permits, file the paperwork, and handle the inspections. Call (817) 686-2228 for an exact permit timeline for your parcel.
Yes. If the sash and frame are sound, we can replace the insulated glass units and keep your original wood. Glass-only replacement runs $90 to $300 per pane depending on size and whether you want low-E or laminated glass. For older Berkeley homes, this often avoids historic review entirely because the window profile does not change.
We are authorized dealers and installers for PGT, CGI, CWS, and ViewLux, along with four other manufacturer lines. The right brand depends on the opening, the exposure, and the house. We spec per opening, not per brand. Call (817) 686-2228 for a written spec and price.
For most of Berkeley, no. Impact-rated glazing is overkill on the flats and the west side. But in the Berkeley Hills, where wind-driven rain and gusts climb, we often specify PGT or CGI units designed for higher design pressures. The extra cost is worth it on exposed hillside openings that a standard unit will not handle.
Honestly, the only thing that changes price is what we find inside the wall: rotted studs, missing framing, or water damage hidden behind the trim. We show you the condition during scope and write the price with the known conditions listed. If we find something hidden, we stop, show you, and get a written change order signed before we proceed. No price moves without your signature. Call (817) 686-2228 for a free estimate and a written line-item quote.
