AfterFast, Reliable Window Replacement Across San Fernando
Window replacement in San Fernando, CA typically runs $850 to $1,400 per window for a standard vinyl insert, and $1,200 to $2,100 for a full-frame replacement on the pre-1978 stucco homes that dominate neighborhoods around the San Fernando Mall and Maclay Avenue. Most full-home jobs in San Fernando take two to four working days once permits clear. We know this market because we work in it every week, including older ranch houses off San Fernando Road and the tighter post-war lots near Rudford’s. Call (682) 281-2168 and we will give you a written line-item price before any work is scheduled.
Why Juniper Windows & Doors Is San Fernando’s Preferred Window Replacement Company
San Fernando homeowners call us because we scope the job the right way on the first visit. A lot of homes here were built before 1978, which means original single-pane aluminum sliders, rough openings that are rarely square, and stucco returns that hide what is actually behind them. Our team is used to re-framing around old wood sills and re-flashing openings that have shifted over decades, and we write the full scope into a fixed price before ordering glass.
Every technician who shows up at a San Fernando home is background-checked and in uniform. You will get a live arrival time you can track, before-and-after photos of the work, and a digital invoice you can pay from a link. Sean Mackey leads the team, and he is the person who reviews every San Fernando project before it gets scheduled. Our Window Replacement crew is built around the Relay Visibility Guarantee, which means no four-hour arrival windows and no mystery about who is walking through your door.
Window Repair in San Fernando
Window repair in San Fernando usually means one of three things: a failed insulated glass unit that has fogged between the panes, a rotted wood sill under an original slider, or hardware that no longer locks or seals. On homes near Maclay Avenue and San Fernando Road, we see the full range. A fogged double-pane sash can often be replaced without touching the frame, which keeps the job small and fast. A rotted sill on a pre-1978 stucco home is a different animal, because the sill is often set into the wall, and cutting it out correctly means protecting the stucco return.
Sash and Glass Replacement
When the frame is still square and solid, we replace just the sash or the glass pack. In San Fernando, this typically runs $350 to $650 per window depending on glass size and whether the unit is Low-E. The work is clean: we pull the old sash, set the new one, and re-seal. Most jobs are done in a single visit.
Frame and Sill Repair
Older San Fernando homes, especially the mid-century builds around the San Fernando Mall area, often have original wood sills that have been absorbing moisture for sixty years. We will cut out the rot, sister in new wood, re-flash the opening, and reset the sash. This runs $400 to $900 per opening depending on how far the rot extends. We write the scope after we open the wall, and the price is locked before we order materials.
Window Replacement Company in San Fernando
A window replacement company working in San Fernando has to understand what is behind these walls. The housing stock here is mostly pre-1978 stucco over wood framing, with single-pane aluminum sliders as the original install. Replacing them well is not a sash swap. It means pulling the old frame, checking the rough opening for square, re-flashing, re-insulating the jamb, and setting a new unit that actually seals. Done right, this runs $1,200 to $2,100 per window for full-frame work. Done wrong, it leaks air and the stucco cracks around the perimeter.
Full Frame Replacement
We remove everything down to the rough opening, fix any framing issues, install a new nailing flange, flash it correctly, and set the new window. This is the right call for most original single-pane sliders in San Fernando, especially on west-facing walls that take the afternoon heat. Expect $1,200 to $2,100 per opening.
Insert Window Replacement
When the existing frame is square and solid, an insert drops into the old opening with minimal disruption to stucco and trim. This is common on San Fernando homes where windows were replaced once already, usually in the 1990s. Inserts run $850 to $1,400 per window, and most are installed in under an hour per opening once the opening is prepped.
Trusted Brands We Service in San Fernando
We install and service PGT, CGI, CWS, and ViewLux product lines, and we carry the parts and hardware those brands need for service calls in San Fernando. If you have an existing PGT slider that has lost its seal, we can source the replacement sash without waiting on a distributor to ship from out of state. For new installs, CWS vinyl double-hungs and casements are a strong fit for San Fernando’s post-war ranches, and PGT impact-rated units make sense for homeowners who want a window that will hold up to wind-blown debris off the Verdugo foothills. We will never push a brand that does not fit your elevation, your budget, or your home’s original framing.
Common Window Replacement Problems We See in San Fernando Homes
- Out-of-square rough openings on pre-1978 stucco homes. The original framing has shifted over decades, and when we pull the old aluminum slider we often find the opening is off by half an inch or more. We fur out the jamb and re-flash before setting the new unit, which is scope that only becomes visible after tear-out.
- Single-pane clear glass on south- and west-facing walls. San Fernando sits in a valley pocket that traps heat, and clear single-pane glass turns a living room into a solar oven by 3 p.m. We spec Low-E insulated glass units with a low SHGC for those elevations, which is the single biggest energy lever most replacement projects have.
- Dry-rotted original wood sills hidden behind old aluminum tracks. Very common around the San Fernando Mall corridor, where original window flashing was never done to modern standards. The sill looks fine from the outside until the old unit comes out.
- Wrong permitting assumptions. San Fernando is its own incorporated city with its own Building & Safety counter. If a contractor assumes LA City or LA County rules apply, the submittal gets rejected and the schedule slips. We handle the City of San Fernando permitting path from start to finish.
Pricing for Window Replacement in San Fernando, CA
Here are honest ranges for the San Fernando market. A standard vinyl insert runs $850 to $1,400 per window. A full-frame replacement on an older stucco home runs $1,200 to $2,100 per window. A full-home job, typically eight to twelve windows, usually lands between $9,000 and $18,000 total, depending on brand, glass package, and what the tear-out reveals. The big cost drivers are frame condition, glass spec, and whether the opening needs re-framing. Juniper Windows & Doors writes every San Fernando estimate as a fixed line-item price before work begins. If tear-out reveals an out-of-square opening that needs furring, we write it into a change order and get your sign-off before ordering glass.

FAQs About Window Replacement in San Fernando
Yes. San Fernando is an incorporated city with its own Building & Safety department, so window replacement permits run through City of San Fernando Building & Safety, not LA City or LA County. The submittal path and inspection lead times are different, and we handle the full permitting process on every job. Call (682) 281-2168 and we will explain exactly what your project needs before we start.
We install PGT, CGI, CWS, and ViewLux, and we stock parts and hardware for those lines locally. For most San Fernando ranches, CWS vinyl double-hungs and casements are the best value. For wind exposure near the foothills, PGT impact-rated units are worth considering. We will spec the right product for your elevation and your budget, not the brand with the best distributor margin.
Most full-home jobs in San Fernando take two to four working days of installation time once the permit is issued and materials are on site. The permit process through City of San Fernando Building & Safety can add one to two weeks depending on current inspection scheduling. Inserts go faster than full-frame work. We give you a realistic calendar before we schedule anything, and the 365-Day Done Right Promise covers parts and labor in writing for a full year.
Yes, and for San Fernando specifically, the biggest lever is glass spec, not just frame material. The valley pocket here traps heat, especially on west- and southwest-facing walls, so we spec Low-E insulated glass units with a low solar heat gain coefficient for those elevations. Homeowners who replace original single-pane clear sliders with Low-E units typically notice a real drop in afternoon heat gain. We recently replaced eight original sliders in a 1950s ranch near Rudford’s on San Fernando Road with CWS units built around Low-E insulated glass, and the homeowners saw their cooling load drop noticeably once the SGHC dropped.
The honest answer is that on pre-1978 stucco homes, tear-out sometimes reveals conditions no one could see from the outside: out-of-square rough openings, dry-rotted sills, or framing that needs furring and re-flashing. On a job off Maclay Avenue we found rough openings out of square by nearly an inch behind the old stucco return, which required furring out the jamb before setting the new sashes. That scope only surfaced after tear-out, and we wrote it into a change order before ordering glass. The price does not change without your written sign-off. Call (682) 281-2168 for an exact quote on your San Fernando home.
