Fast, Reliable Window Installation Across Covina
Window installation in Covina runs anywhere from $450 for a basic single-hung insert to $2,400+ for a custom casement or bay unit with stucco repair, and most full-home jobs land between $8,000 and $22,000 depending on frame condition and glass package. The bigger variable in Covina isn’t the window. It’s the house. Homes near downtown were built when rough openings were framed by hand, and they rarely match modern stock dimensions. Homes in Covina Hills were framed in the 80s and 90s with larger openings, vaulted sightlines, and bigger glass. Both require a different approach, and that’s the work we do every week here.

Why Meridian Windows & Doors Is Covina’s Preferred Window Installation Company
We show up when we say we will. That sounds simple, but Covina homeowners who’ve been burned by a no-show contractor tell us it’s the reason they call us back for the next project. Every crew member is background-checked and uniformed, so you know who’s at the door before you open it. The phone is answered by a live person 24 hours a day, every day of the year, including holidays. No voicemail loop, no “we’ll call you back Tuesday.”
Meridian Windows & Doors is part of the Garrison Partners family and has operated to The Garrison Standard since 2009. That standard means every job gets a written price before work begins, and every installation is covered by our 365-Day Done Right Promise. If the work fails within that year, we return at no charge. No fine print about labor exclusions. No argument. We also keep eight manufacturer lines in our portfolio, including CGI, CWS, and ES Windows, so the right unit is spec’d for your opening rather than whatever happens to be sitting in a warehouse.
A meridian is a fixed line you measure everything against. That’s what the name means, and it’s how we run every install in Covina.
Casement Windows in Covina
Casement windows in Covina work well in the pre-1960s tracts near downtown, where older homes often have narrow vertical openings that don’t suit wide sliders or double-hungs. A casement hinges on one side and cranks outward, which gives you the full opening for cross-ventilation, something that matters in Covina’s summer months when the San Gabriel Valley heat settles in. Expect to pay $750 to $2,200 per casement unit installed, with labor and standard low-E glass included. Custom sizing for out-of-square rough openings in older Covina homes adds $150 to $400 per window depending on how far the jamb is off.
Where Casements Make Sense in Covina
West-facing bedrooms and living rooms in Covina get hammered by afternoon sun from roughly May through October. A casement with low-E glass, which is a thin coating that reflects heat while letting light through, cuts that gain noticeably. We’ve also installed casements in second-story Covina homes where the crank mechanism makes opening and closing far easier than lifting a double-hung sash over a stairwell.
What Casement Installation Involves
We remove the old sash and frame, check the rough opening for square, shim where needed, set the new unit, flash and seal the exterior, and patch any cracked stucco around the opening. On older Covina homes, that stucco work is almost always part of the job, and we plan for it up front rather than surprising you halfway through.
Double Hung Windows in Covina
Double hung windows in Covina are the most common replacement we install in the downtown tracts, particularly on the 1940s and 50s ranch homes along streets like Cypress and Citrus. Both sashes move vertically, which means you can open the top, the bottom, or both for ventilation. A standard double-hung replacement in Covina runs $550 to $1,400 per unit installed. If the existing jambs are rotted or badly out of square, which we see regularly in homes that have been through 60+ Covina summers, expect to add $100 to $300 per opening for jamb repair or replacement.
Why Older Covina Homes Need Jamb Work
Downtown Covina homes were framed before modern dimensional lumber standards. The rough openings are often off by a half-inch to an inch, and the original wood jambs have shifted over decades of ground settlement. A stock double-hung won’t sit square in that opening. We sister new jamb liners, shim the frame until it’s plumb and level, and then set the sashes. Skip that step and the window binds, leaks air, and voids the manufacturer’s warranty.

What We Installed on Cypress Street
We installed eight double-hung ECO Window Systems units with low-E insulated glass in a 1950s ranch home near Cypress Street and Citrus Avenue in downtown Covina. The original wood jambs were out of square by nearly an inch, so our tech sistered new jamb liners before setting the sashes and finished with stucco patching around each opening. The homeowner told us the west-facing rooms stayed noticeably cooler that first summer.
Trusted Brands We Service in Covina
We’re authorized to install and replace products from CGI, CWS, and ES Windows, plus five other manufacturer lines. That matters in Covina because the right window for a 1950s downtown ranch isn’t the same unit that belongs in a 90s Covina Hills build with a 6-foot rough opening. We don’t push one brand, and we don’t stock a single line and call it a day. If you already have a window brand you trust, we’ll work within that line. If you want a recommendation based on your home’s orientation, frame condition, and budget, we’ll make one. Parts and replacement units for Covina customers are ordered the same week we scope the job.
Common Window Installation Problems We See in Covina Homes
- Stock-size orders that don’t fit the rough opening. Covina’s downtown homes frequently have non-standard jamb depths and out-of-square frames. Ordering a stock unit before measuring the actual opening forces a reorder and adds two to three weeks to the schedule. We measure every opening on-site before ordering anything.
- Unplanned stucco repair. Removing old windows in Covina’s mid-century neighborhoods inevitably cracks the surrounding stucco. If the estimate doesn’t include patching and texture matching, you’ll get a change order mid-job or a gap left around the new frame. We plan stucco work into the written price up front.
- Permit timeline surprises. Covina’s building department processes residential window permits on its own schedule, which doesn’t always match neighboring cities. A job that sails through West Covina in a week might take two or three in Covina. We handle the permit paperwork and build that timeline into the schedule before we start.
- Retrofit vs. full-frame confusion. A retrofit insert into an existing frame is cheaper, but if the frame is rotted, you’re paying to dress up a problem that will fail. In Covina’s older homes, we flag frame condition during the estimate and recommend full-frame replacement when it’s honest to do so.

FAQs About Window Installation in Covina
Yes, Covina requires a building permit for window replacement when the opening size changes or when going from a retrofit to a full-frame install. If you’re swapping like-for-like inserts into existing frames, the permit requirement may not apply, but we confirm with Covina’s building department on every job rather than guessing. We pull the permits, schedule the inspections, and make sure the job passes before we call it done. Call (817) 686-2228 and we’ll check your specific project before you commit.
A standard single-window replacement in Covina takes one day of on-site work. A full-home job of 8 to 14 windows typically runs three to five working days, depending on stucco repair volume and whether Covina’s inspection schedule adds a day. The bigger time variable is the permit turnaround and any custom-unit lead time, which runs two to four weeks for non-stock glass packages. We give you a calendar with dates on it before work starts, not a vague “soon.”
Double-hung windows have two sashes that slide vertically, while casement windows hinge on one side and crank outward. For Covina’s older ranch homes, double-hungs match the original look and are easier to retrofit into existing openings. Casements seal tighter against drafts and give you full-opening ventilation, which helps on hot Covina afternoons, but they require more clearance to swing open. Both are solid choices here; the right one depends on your room layout and whether you want to preserve the home’s street appearance.
Yes, though the size of the drop depends on your current glass and your home’s insulation. Covina regularly sees summer highs above 90 degrees, and single-pane windows from the 1950s transfer a lot of that heat into your rooms. Low-E insulated glass, which reflects thermal energy while letting visible light through, typically cuts window-related heat gain by 30 to 50 percent. West-facing rooms see the biggest difference. We can’t promise a specific dollar figure on your utility bill, but we can show you the difference in glass specs before you choose.
The honest answer: rotted framing, unexpected termite damage, or stucco that crumbles when the old window comes out. On Covina’s older homes, the frame behind the drywall is sometimes in worse shape than the window itself, and there’s no way to fully know until the old unit is out. That’s why our written estimate includes a line item for known stucco repair and a clear note on what we do if we find hidden damage. We stop, show you what we found, and give you the number before we proceed. No change order gets added without your sign-off. Call (817) 686-2228 for a free estimate and we’ll walk through what’s likely on your specific home.
