Fast, Reliable Window Replacement Across Oakland
Drafty windows in an Oakland home are not a cosmetic problem. Fog rolling off the bay, June gloom stretching into July, and a century-old sash rattling every time a BART train rumbles past Rockridge – these are the daily reminders that your windows have stopped doing their job. Window Replacement in Oakland usually runs $650 – $1,400 per window installed, depending on size, frame condition, and glass package. We serve every Oakland neighborhood, from Montclair to Fruitvale to the flatlands off International Boulevard, with a written price before any work starts. Call (682) 281-2168 for a free estimate.
The housing stock here throws curveballs contractors in newer cities never see. Edwardian and Craftsman frames with single-pane glass, hillside homes where the wind never really stops, and marine air that eats soft wood sills from the inside out. Sean Mackey and our crews know which frames in the Laurel District tend to hide dry rot behind the trim, and why homes in the Oakland Hills need Mr Glass repair in Oakland more than their neighbors down by Lake Merritt. Local knowledge changes how we quote, how we prep, and how long the job takes.
Why Juniper Windows & Doors Is Oakland’s Preferred Window Replacement Company
We have been replacing windows in Oakland long enough to know that no two jobs here look alike. A bungalow off Park Boulevard has different framing than a 1980s condo near Jack London Square, and we treat them that way. Our Oakland customers consistently point to the same three things in their feedback: the written price that does not move, the live arrival time they can actually track, and crews who leave the job site cleaner than they found it.
Every technician who walks through your door is background-checked and uniformed. You will know their name before they arrive, see before-and-after photos of the install, and get a digital invoice you can pay from your phone. Founded in 2001, Juniper Windows & Doors is part of the Relay Home Co. family and runs on the Relay Standard: book in a tap, live arrival time, photo updates, written price, no surprises. Our response time to Oakland is same-day for quotes in most neighborhoods, and we carry local inventory for the common glass sizes found in Oakland’s older housing stock, so lead times stay short.
Sean Mackey leads the Oakland team with a straightforward rule: if the work is not done right, we make it right, for a full year after installation. That is the 365-Day Done Right Promise, and it covers parts and labor, in writing, on every project we do.
Window Sash Replacement in Oakland
Window Sash Replacement in Oakland means swapping out the movable part of the window – the frame that holds the glass – without tearing into the surrounding wall. It is the most common job we do in Oakland’s older neighborhoods, where the original double-hung frames are often worth keeping. When the sash itself is rotted, warped, or no longer seals, you get a fresh sash that slides cleanly and locks tight, usually in a single day. Expect to pay $450 – $900 per sash in Oakland, depending on wood versus vinyl and whether we are matching an existing profile in a historic district.
Rotted Wood Sash Frames
Homes in Crocker Highlands and Trestle Glen have beautiful original woodwork that the marine layer works against year-round. Soft sashes let air in, let heat out, and eventually stop opening altogether. We rebuild or replace the sash before the rot spreads to the jamb and turns a repair into a full-frame job.
Fogged or Broken Sash Glass
When the seal fails on a double-pane sash, condensation gets trapped between the glass and it looks cloudy from the street. We replace the glass or the entire sash, and the new unit carries the same 365-Day Done Right Promise as a full replacement.
Window Glass Repair in Oakland
Window Glass Repair in Oakland addresses cracked panes, failed seals, and impact damage without necessarily replacing the whole window. If the frame is sound and only the glass is compromised, this is the fastest and least expensive fix. Oakland pricing for glass replacement runs $175 – $550 per pane for standard sizes, more if the glass needs to be tempered for safety near doors or low to the floor.
Cracked Panes from Hillside Wind
The Oakland Hills get gusts that never show up in weather apps. A pine branch, a loose lawn chair from a neighbor’s deck, a pebble kicked up by a windstorm off Highway 13 – these cause cracks that start small and spider across the pane within days. Same-week glass replacement keeps the glass from failing completely and the home exposed.
Failed Insulating Glass Units
If a double-pane window fogs from the inside and wiping does not fix it, the insulated glass unit has failed. We measure, order, and install a new IGU, and explain the U-factor on the replacement so you know exactly what thermal performance you are getting.
Trusted Brands We Service in Oakland
We stock and service PGT, CGI, and ES Windows product lines for Oakland homes, which means faster turnaround when a window needs matching hardware, a replacement sash, or a warranty part. PGT’s impact-rated glass is a natural fit for hillside exposure and upper-floor installations. CGI carries heavy-duty frames that hold up to the temperature swings between Oakland’s fog belt and the warmer flats. ES Windows gives us a clean, narrow sightline option for mid-century homes in the Oakland Hills where the view matters as much as the seal. We keep common parts for these brands on hand so Oakland customers are not waiting on a shipment from across the country.
Common Window Replacement Problems We See in Oakland Homes
- Single-pane glass in pre-1950 homes. Most Oakland homes built before the 1950s still have their original single-pane windows. In the Rockridge and Temescal flats, that means heat pours out in winter and traffic noise from Highway 24 never really leaves the living room.
- Dry rot from fog and coastal moisture. The same marine layer that cools summer afternoons here also sits against wood frames for hours each night. We regularly open up trim in the Dimond District and find sills that looked fine from the outside but crumble when touched.
- Stuck double-hung windows in hillside homes. Hillside houses and their shifting soils create subtle frame settling that binds old sashes. Homeowners in the Montclair area often call us after years of using a broomstick to prop a window open, and a replacement sash or full-frame window solves it permanently.
- Poorly installed retrofit windows from decades past. Oakland saw a wave of insert-window retrofits in the 1980s and 1990s, and many were cut flush to bad wood. We see gaps behind the trim near Lake Merritt and in the Adams Point area that were never insulated or sealed, leaking air the whole time.
Pricing for Window Replacement in Oakland, CA
Here is what you can expect to pay in Oakland’s market right now.

Oakland pricing runs slightly higher than the outer East Bay suburbs because of the age of the housing stock and the hillside access on many properties. Figure $650 – $1,400 per window installed in Oakland, versus $600 – $1,200 in flatter areas like Alameda and San Leandro. The difference comes mostly from added labor on older frames and upper-floor work.
