Fast, Reliable Window Installation Across San Bernardino
Window installation in San Bernardino costs between $450 and $1,850 per window for most homes, with full-home projects of 10 windows typically landing between $6,500 and $14,000. The range depends on window type, frame material, glass package, and whether your home sits in a wind zone that requires impact-rated glazing. We know this market cold because our dispatch and scheduling runs from our Inland Empire office, and crews serve San Bernardino neighborhoods like Del Rosa, North Park, and Verdemont every week. Call (682) 281-2168 to get a written price before any work starts.
Why Juniper Windows & Doors Is San Bernardino’s Preferred Window Installation Company
Sean Mackey leads our window installation team, and he runs every San Bernardino project on one rule: a written price before a single screw turns. That’s not a slogan. It’s how we’ve operated since 2001, and it’s the reason homeowners off Highland Avenue, in the Shandin Hills, and around Perris Hill Park keep calling us back when they’re ready for the next window batch.
We’re not a general contractor who happens to install glass. Window Installation is what we do, full stop. Our technicians are background-checked and uniformed, so when someone knocks on your door in San Bernardino, you know exactly who you’re letting in. And when you call our line at (682) 281-2168, a real person answers. 24/7. No voicemail maze, no callback queue.
Every project carries the 365-Day Done Right Promise. If something isn’t right after installation, we make it right, parts and labor, in writing, for a full year. We also hand you the Relay Visibility Guarantee: a live arrival time you can track, before-and-after photos of every job, and a digital invoice you can pay from a link. The whole experience feels less like construction and more like the rideshare apps you already use daily.
San Bernardino has its own building codes, its own wind exposure maps, and its own permitting quirks. We know what the city asks for, we pull the permits ourselves, and we pass inspections. That local knowledge saves you days of back-and-forth and keeps your project from stalling at the counter.
Casement Windows in San Bernardino
Casement windows are a smart choice for San Bernardino homes because they hinge on one side and crank outward, sealing tight against the frame when closed. That tight seal matters here more than most places: our valley gets hard Santa Ana gusts, and a poorly sealed window will whistle, leak dust, and spike your cooling bill from May through October. A casement window in San Bernardino typically runs $550 to $1,400 per unit installed, depending on size and glazing.
Impact-Rated Glass Options
Many San Bernardino neighborhoods sit in high-wind and wildfire-prone zones, which changes what glass belongs in your frames. Impact-rated casement windows use a laminated interlayer that holds the glass together even if wind-borne debris hits it. That’s not a suggestion in parts of this city; it’s what the design pressure calculations require.
Airtight Sealing for Santa Ana Season
Casements seal on all four sides with compression weatherstripping, which makes them one of the better options for keeping Santa Ana-driven dust and wind out of your living room. We’ve replaced older sliding windows with casements throughout North Park and noticed an immediate difference in indoor comfort during the fall wind season.
Double Hung Windows in San Bernardino
Double hung windows remain one of the most common upgrades in San Bernardino’s older housing stock, especially the 1950s and 1960s ranch homes that line streets off Baseline and Waterman. Both sashes move up and down, which gives you ventilation from the top or bottom, a real advantage when you’re trying to flush hot air out of a bedroom on a July evening. Expect to pay $480 to $1,250 per double hung window installed in this market.
Low-E Glass for Inland Empire Heat
San Bernardino regularly sees summer days above 100 degrees, so glass coatings are not an upsell here; they’re the point of the job. We spec low-E insulated glass units on nearly every double hung install we do in the city. The coating reflects heat back outside while still letting light through, which keeps your AC from running constantly against south-facing and west-facing glass.
What We See in Older San Bernardino Framing
Double hung replacements in older San Bernardino homes often uncover rot or termite damage in the rough opening once the old frame comes out. We don’t cover that up. We photograph it, show you exactly what we found, and put the repair cost on the same written estimate before we proceed. No surprise invoice at the door.
Trusted Brands We Service in San Bernardino
We install and service window lines from PGT, CGI, and CWS, among others. These are the brands we trust for San Bernardino’s specific mix of wind exposure, wildfire proximity, and extreme summer heat. Because our Inland Empire office stocks common parts and hardware for these lines locally, we can often turn around a repair or replacement sash in days, not the weeks a distant distributor might quote. If you have CGI or PGT windows already in your home and a seal has failed or a sash won’t lock, call us. We don’t just install new; we maintain what’s already there.
Common Window Installation Problems We See in San Bernardino Homes
- Improper flashing and sealing at the rough opening. We see this constantly on San Bernardino homes, especially where a previous contractor skipped flexible flashing tape or caulked over old, cracked sealant. During Santa Ana wind-driven rain, water finds those gaps and runs into the wall cavity before you ever see a stain on the drywall.
- Non-impact-rated glass in high-wind zones. Some homeowners try to save money by installing standard annealed glass in areas where San Bernardino’s wind exposure maps call for impact-rated glazing. When debris hits that glass, it shatters into dangerous shards. We won’t install a window that fails the design pressure requirement for your specific lot.
- Permits skipped entirely. Window replacement in San Bernardino requires a permit, and code enforcement does catch unpermitted work. We pull the permit ourselves, schedule the inspection, and make sure the job passes before we call it done.
- Faded, failed seals on sun-blasted west-facing windows. The afternoon sun off the San Bernardino Mountains border beats on west-facing glass for hours. Failed seals show up as fog between the panes, and they’re especially common in neighborhoods like Verdemont where homes sit at higher elevation with less shade cover.
Pricing for Window Installation in San Bernardino, CA
Here’s what you can expect to pay for window installation in San Bernardino, based on the projects we’ve scoped recently:
- Double hung windows: $480 – $1,250 per window installed
- Casement windows: $550 – $1,400 per window installed

Your specific price moves based on glass package (low-E, impact-rated), frame material (vinyl, aluminum, or composite), window size, and what we find in the rough opening once the old unit comes out. A 1960s ranch home with original single-pane windows often needs jambs rebuilt before the new window goes in, and that adds real labor.

FAQs About Window Installation in San Bernardino
Yes. San Bernardino requires a building permit for window replacement, even when you’re swapping like-for-like sizes. The permit ensures the installation meets current energy code (Title 24) and any wind load requirements for your specific zone. We pull the permit as part of every job and handle the inspection scheduling. Call (682) 281-2168 and we’ll walk you through the permit timeline for your address.
Impact-rated glazing is glass with a laminated interlayer (typically PVB or SGP) sandwiched between two panes, so it holds together when struck by a branch, tile, or other wind-borne debris. San Bernardino sits in a high-wind exposure zone, especially along the foothills and canyon mouths where Santa Ana winds funnel hard. Many homes here are required to meet specific design pressure ratings, and impact-rated glass is how you do that without boarding up. It also adds a layer of wildfire ember protection by keeping glass intact longer.
Yes, especially if your home still has single-pane windows. Upgrading to double-pane low-E insulated glass units typically cuts heat gain through windows by 30 to 50 percent, which translates directly into lower AC runtime from June through September. We recently installed double hung and casement windows from PGT and CGI in a 1960s ranch home off Highland Avenue in the Del Rosa area. The original single-pane windows had failed seals and the owner wanted low-E insulated glass units to cut summer cooling costs. After pulling the city permit and passing inspection, we upgraded the jambs and sashes, resulting in a tighter envelope and a projected 20 to 30 percent drop in cooling bills. Call (682) 281-2168 to get a written price on your project.
We install PGT, CGI, CWS, ES Windows, and several other trusted lines. PGT and CGI are the most common choices for San Bernardino projects because both offer impact-rated products engineered for high-wind inland climates. If you want a specific brand, tell us; we’re not limited to one manufacturer’s catalog. Estimates are free at (682) 281-2168.
Most single-window replacements take 1 to 2 hours once we’re on site, including removal, prep work, installation, and cleanup. A full house of 8 to 12 windows usually takes 2 to 3 days, not including drywall or stucco patch time if the old openings were damaged. Permits and inspections add a few days to the calendar depending on city scheduling. We’ll give you a day-by-day plan in writing before you commit. Call (682) 281-2168 for an exact timeline on your job.
