Window installation in Westminster, CA runs $650 – $1,850 per window for most retrofit and full-frame replacements, with whole-home projects typically landing between $9,000 and $28,000 depending on window count, glass packages, and frame condition.

Call (817) 686-2228 for a written price before any work is scheduled, and we’ll walk you through exactly what your project needs.
We know how Westminster homes were built. Many of the single-story ranchers and two-story stucco boxes here went up in the 1960s and 1970s, which means original aluminum frames, single-pane glass, and window openings that have settled out of square over the decades. That changes how we measure, order, and install. The work has to account for the existing rough openings, the stucco returns, and the local code requirements that have tightened significantly since those homes were framed.
Why Meridian Windows & Doors Is Westminster’s Preferred Window Installation Company
Elliot Vance runs our window installation team, and he runs it on a simple rule: the price goes on paper before a single screw turns, and it does not move at the door. Homeowners in Westminster have dealt with enough contractors who quoted one number and invoiced another. That’s not how we operate. A meridian is a fixed line you measure everything against, and that is what the name means and how we run every install.
We’re part of the Garrison Partners family, held to The Garrison Standard since 2009. Every job gets a written 365-Day Done Right Promise: if the work fails within a full year, we come back at no charge. No fine print about labor exclusions. The crew shows up in uniform, background-checked, and you’ll know exactly who is walking through your door. We stock product from eight manufacturer lines, including PGT, CGI, and CWS, so the right window is spec’d for the job, not the one that happens to be in stock at a distributor’s warehouse.
Our scheduling and dispatch is coordinated from the brand’s Los Angeles office, but the crews serving Westminster work locally and know the streets, the housing stock, and the permit office routines.
Casement Windows in Westminster
Casement windows in Westminster are a common replacement choice for the wide picture openings on 1970s ranch homes, and a full-frame casement install here runs $900 – $1,650 per opening, depending on glass and hardware. Casements hinge on the side and crank outward, which gives them a tighter air seal than sliding or double-hung styles when closed. That matters in Westminster, where coastal breezes and Santa Ana gusts both find their way through loose weatherstripping on older units.
When a Westminster homeowner asks for maximum ventilation and a clean sightline, a casement is usually the right call. They work well in kitchens over sinks, in living rooms where a central picture window doesn’t open, and in west-facing bedroom walls where you want to catch the late afternoon ocean air while keeping the sun’s heat under control.
Frame and Glass Considerations
On casement replacements in Westminster, we pay close attention to the crank hardware and the sash seal. Older casements with stripped cranks or warped frames get replaced as a complete unit, not patched. The glass package matters too. For west-facing exposures, we typically spec low-E glass with a SHGC tuned for climate zone 8 compliance, which keeps the room cooler without sacrificing visible light.
Measurement in Out-of-Square Openings
Westminster homes from the 1960s and 1970s often have window openings that are no longer perfectly square. That is a fact of framing we deal with constantly. A casement still works in these openings because the crank mechanism pulls the sash tight against the frame on all four sides, which gives you a better seal than a sliding sash in the same rough opening.
Double Hung Windows in Westminster
Double hung windows in Westminster are the most requested style for two-story 1980s stucco homes and the ranch models that line the streets near Westminster Boulevard, with installed pricing for our work running $700 – $1,750 per window for full-frame replacement. Both sashes move up and down, which is why they remain the default choice for bedrooms and living rooms where easy cleaning and traditional proportions matter.
The double hung’s real advantage in Westminster is flexibility. You can open the top sash to release hot air while keeping the bottom closed, which helps on warm afternoons when the marine layer hasn’t arrived. On upper-story windows, tilt-in sashes mean you can clean the outside glass from inside the house, which matters on the second floor of a two-story Westminster home where an extension ladder isn’t practical.
The Retrofit Question
We always check the condition of the existing jamb liners and balances before recommending a retrofit double hung. On 1970s-era aluminum frames that have corroded near the coast, we strongly recommend a full-frame replacement rather than bolting new sashes into tracks that are already binding. A retrofit into compromised frames fails within a season, and it won’t hold air the way a new frame will.
Noise Reduction on Busy Corridors
Homes near Bolsa Avenue or Westminster Boulevard deal with constant street noise, and a double hung with laminated glass makes a measurable difference. We regularly spec laminated glass on the street-facing side of Westminster homes to cut the traffic drone, and the same package improves the DP rating for wind exposure. The two goals line up more often than not.
Trusted Brands We Service in Westminster
We are authorized to install and replace products from PGT, CGI, and CWS, among the eight manufacturer lines we carry. The brand decision depends on the specific opening, the exposure, and the budget in front of us. For Westminster’s climate zone 8 requirements, CWS and PGT both offer glass packages that hit the U-factor and SHGC numbers the city’s Title 24 compliance check will require. Because we stock these product lines locally for our Westminster customers, we aren’t waiting on a distributor in another county when a sash needs to be reordered or a hardware component fails at inspection. That shortens lead times and keeps the job on schedule.
Common Window Installation Problems We See in Westminster Homes
- Skipped Title 24 compliance checks. Westminster sits in climate zone 8, and the city requires specific U-factor and SHGC values for replacement windows. We see homeowners order glass that misses the mark, and then the permit gets flagged and the whole order has to be redone. We verify compliance before anything is ordered.
- Reusing corroded 1970s aluminum frames in a retrofit. Near the coast, the original frames on older Westminster homes often have corrosion inside the tracks. New sashes bolted into those frames bind within months and leak air. Full-frame replacement costs more, but it is the right fix when the frame is already failing.
- Guessing design pressure on second-story units. Westminster’s wind exposure changes by street and structure height. A miscalculated DP rating on an upper-floor window means a failed inspection and a reorder. We check the exposure category on every opening before we spec glass.
- Ignoring west-facing heat gain. The afternoon sun on a west-facing Westminster bedroom is relentless, especially during summer. Without a low-E coating tuned for that exposure, the room cooks. We see homes where new windows were installed without anyone checking which direction the glass faced.
Pricing for Window Installation in Westminster, CA
Most single-window replacements in Westminster run $650 – $1,850 installed, and the biggest cost drivers are frame condition, glass package, and whether the opening needs a full-frame replacement or can take a retrofit unit. A typical casement runs $900 – $1,650. A double hung runs $700 – $1,750. Whole-home projects across 8 to 15 openings usually land between $9,000 and $28,000.
We also serve Westminster with pricing that reflects the real conditions of the house, not a national average. Laminated glass for noise reduction, low-E coatings for Title 24, and custom sizing for 1970s openings all move the number. You get a written line-item quote before anything is scheduled, and that quote is the price. Call (817) 686-2228 to schedule a free estimate.

FAQs About Window Installation in Westminster
Yes, Westminster requires a building permit for window replacement when the opening size changes or the installation is a full-frame replacement, and the city enforces Title 24 energy compliance for all window work in climate zone 8. Retrofit installations into existing frames sometimes fall under a simpler process, but we always verify with the city before ordering product. Call (817) 686-2228 and we will check your specific openings and tell you what applies.
A fixed or casement window with low-E insulated glass and a SHGC rating tuned for west-facing exposure works best, because it blocks the late heat gain while keeping the room bright. In Westminster’s climate zone 8, we spec a glass package that hits the energy numbers the city inspects and cuts the actual heat load on the room. Casements give you ventilation when the ocean breeze picks up; fixed picture windows give you the widest view with no moving parts to maintain.
Most Westminster homes with 8 to 10 replacement windows take two to four working days from first window out to final trim and cleanup, assuming the openings need no structural correction. Full-frame work runs slower than retrofit, and custom sizing for older openings adds lead time before the install date. We give you a calendar with the written quote, so you know the schedule before you commit. Call (817) 686-2228 for a project-specific timeline.
Yes, laminated glass reduces street noise measurably. Laminated glass uses an interlayer between two panes that disrupts sound transmission, and it works well on busy corridors like Bolsa Avenue and Westminster Boulevard where traffic is constant. The same lamination also raises the design pressure rating, so one upgrade solves two problems on a noisy, exposed wall.
The window fails inspection, and the unit must be reordered with the correct DP rating, which adds weeks and cost to the job. We check the wind exposure category for each opening before ordering, so the unit arrives with the right structural rating the first time. The Garrison Code is how we run every job: measure, verify, order, install, inspect. No skipped steps and no hoping the inspector won’t look.
