New Window Installation Cost Breakdown (2026)
Here’s what our team sees across the West Covina market in 2026, broken down by window type and frame material. These numbers include tear-out of the old window, proper flashing, insulation, trim work, and haul-away.
| Window Type / Frame | Installed Cost Per Window | Notes |
|---|---|---|
| Vinyl, double-pane, standard size | $300 – $750 | Best value for most West Covina homes built after 1980. |
| Vinyl, double-pane, custom size | $600 – $1,000 | Older homes with non-standard openings, especially in the South Hills neighborhoods. |
| Fiberglass, double-pane | $900 – $1,400 | Better insulation numbers, more color options, longer lifespan. |
| Wood-clad, double-pane | $1,100 – $1,800 | Common request in the East Hills and Country Squire areas where homes lean traditional. |
| Impact-rated vinyl (hurricane/storm) | $800 – $1,500 | PGT, CWS, and ES Windows lines. Built to take wind-borne debris without shattering. |
| Impact-rated aluminum | $1,000 – $1,800 | Common on mid-century homes that want to keep the original sightlines. |
| Picture window (large fixed, no opening sash) | $500 – $1,200 | Lower labor, but glass and framing add up fast on big spans. |
| Bay or bow window (full assembly) | $2,500 – $5,500 | Includes structural bracing, seat framing, roof cap, and finish work. |
| Garden window (kitchen bump-out) | $1,800 – $3,800 | Includes shelf kit and exterior support brackets. |
Labor-only rates for retrofitting into existing openings run $100 to $300 per window. Full new-construction installs, where the exterior wall is opened and reframed, add $150 to $400 per window on top of material costs.
One note specific to West Covina: homes built from the 1950s through the 1970s frequently have aluminum single-pane frames that weren’t flashed well to start with. When we remove those, we often find dry rot at the sill and water damage in the rough opening. That remediation work is where costs can tick upward by $200 to $800 per opening, depending on how far the damage runs. We show you photos of everything we find before any additional work is approved. If it’s not in writing, it’s not happening.
Per-Window Price Ranges by Brand (Installed)
Juniper Windows West Covina carries eight product lines, and each hits the market at a different price point. Here’s what we quote most weeks:
- PGT (impact-rated vinyl, heavy Southeast/Southern California wind spec): $800 – $1,500
- CGI (high-end impact aluminum, the pick for coastal-adjacent homes that want narrow frames): $1,100 – $2,200
- CWS (architectural impact, big custom sizes): $1,300 – $2,800
- ES Windows (premium aluminum, clean sightlines): $1,000 – $2,400
- ECO Window Systems (aluminum, strong value for large sliders and fixed lites): $700 – $1,600
- Mr-Glass (residential vinyl, best price-per-performance in the lineup): $300 – $700
- Therma-Tru (we use their door lines alongside window jobs; entry doors with sidelites): $2,500 – $6,000
- ViewLux (vinyl, differentiates on glass packages): $500 – $1,100
These aren’t catalog prices. They reflect what we install them for in West Covina, with our labor and warranty included. If you want a firm quote on a specific line, call (350) 305-4609 and ask for Sean’s team.
What Affects New Window Installation Pricing in West Covina
- Frame material. Vinyl runs the least, aluminum sits in the middle, fiberglass and wood-clad run the most. The spread is $300 to $1,800 per window. If you’re replacing windows in a rental unit near the Westfield mall, vinyl usually makes the math work.
- Glass package. Dual-pane with Low-E and argon fill is now the baseline in Southern California, not an upgrade. But switching from standard dual-pane to impact-rated glass (built to resist wind-borne debris without shattering) adds $300 to $800 per window depending on size and brand.
- Home age and rough-opening condition. The 1950s-1970s neighborhoods, including tracts down toward the 10 Freeway, were framed when flashing standards were loose. Damaged sills and water-rotted framing add $200 to $800 per opening in remediation before the new window goes in.
- Window size and shape. A standard 36×48 double-hung is the cheap end. Arch-tops, circles, transoms, or any window that requires a custom template pushes cost up 30% to 70%. Big custom trapezoids in a hillside home get pricey fast.
- Second-story access. Most West Covina homes are single-story, but the hillside neighborhoods (South Hills, parts of East Hills) bring elevation into play. Upper-floor work requires scaffolding or lift work on some lots, adding $100 to $250 per window in labor.
- Wall construction. Stucco is the dominant exterior in West Covina, and it’s forgiving when we cut a clean rectangle. But homes with brick veneer or stone accents around window openings cost more to cut, prep, and flash properly.
How the Installation Process Works in West Covina
Here’s what a new window installation looks like with us, start to finish:
- You call or book online. A live person answers, 24/7. No voicemail maze. We schedule a walkthrough at a time that works, including evenings and weekends.
- We measure and quote in writing. Sean or one of our background-checked installers comes out, measures every opening, checks for rot and structural issues, and puts a line-item price in your hands before we leave. That price holds.
- You order. We place the order with whichever of our eight product lines fits your home and budget. Lead times run 4 to 8 weeks for most lines, a little longer for custom impact-rated from CGI or ES Windows.
- Install day. You get a live arrival time you can track on your phone. The crew shows up uniformed, drops floor protection, removes the old windows, preps the openings, installs and flashes the new units, insulates the gap, trims the interior, and hauls away everything.
- Photo proof and digital invoice. Before and after photos of every window. You pay from a link. The 365-Day Done Right Promise starts the moment the job is signed off: if anything isn’t done right, parts and labor are covered in writing for a full year.
That’s the New Window Installation in West Covina process, and it doesn’t change whether you’re putting Mr-Glass vinyl in a 1960s ranch or CGI impact windows in a hillside custom. The written price is the price.
How to Save on New Window Installation
Saving money on windows isn’t about finding the cheapest possible unit. It’s about avoiding the reasons projects go over budget. Here’s what we tell West Covina homeowners who ask:
- Replace all windows at once, not one at a time. Mobilization cost, crew scheduling, and haul-away all amortize better across 8 to 12 windows than they do across 2. You’ll pay less per window on a full-home job.
- Stick with standard sizes. If a window opening can accept a stock size (even with a small amount of trim adjustment), choose the stock unit. Custom sizing is a real line item: often $150 to $400 per window extra.
- Choose vinyl for rentals and flips. If you’re updating a rental near Nogales Street or a flip in the Citrus district, Mr-Glass or ViewLux vinyl at $300 to $750 installed is the smart play.
- Think about energy savings over time. Dual-pane Low-E windows reduce heat gain in West Covina summers. A home with single-pane aluminum is bleeding air conditioning cost every month. The window upgrade pays back in lower peak-season bills, and it’s not a small number in July and August.
- Get quotes that include everything. Tear-out, flashing, insulation, trim, and haul-away should all be in the number. A quote that doesn’t include flashing or stucco repair isn’t cheaper, it’s incomplete. Our estimates are free and written line-by-line. Call (350) 305-4609 to schedule one.
Is It Cheaper to Repair or Replace Windows?
For a failed seal (fog between the panes), a sash replacement runs $180 to $450 and buys the window another 5 to 10 years. For a broken latch, roller, or balance, you’re looking at $85 to $220 in parts and labor. But if the frame is warped, the glass is cracked, the window is single-pane aluminum, or you’re seeing water stains at the bottom corners, replacement is almost always the better use of money. A full-frame replacement on a rotted opening fixes the root cause; a patch job buys time but not much of it. Most homeowners in West Covina reach out for a quote only after they’ve chased a few repair bills and realized the old windows are done. We’ll tell you honestly which way to go. Call (350) 305-4609 and we’ll take a look.
West Covina Window Installation Costs: A Word on Climate and Code
West Covina sits in a Southern California climate zone with hot, dry summers and cool, mild winters. That means windows here get pushed hard by ultraviolet exposure and temperature swings. The reason we recommend Low-E glass on virtually every project is that it cuts solar heat gain without reducing visible light, which matters when your west-facing living room catches the full afternoon sun from June through September.
On the code side, California’s Title 24 energy standards apply to window replacement. New windows must meet prescriptive U-factor and Solar Heat Gain Coefficient (SHGC) requirements for this climate zone. U-factor is the rate heat moves through the glass: lower is better. SHGC measures how much solar radiation the window lets in: in West Covina, a lower SHGC on west and south facing glass keeps cooling costs in check. Every window we install meets or exceeds the current Title 24 requirement for this zone. We don’t offer non-compliant windows as a “budget option.” It’s not worth the trouble for you or for us.
FAQs – New Window Installation Cost
How much does a full house of windows cost in West Covina?
A full house of 10 standard double-pane vinyl windows in West Covina typically costs $4,500 to $9,000 installed. If you’re going with impact-rated glass or fiberglass frames, the same house runs $10,000 to $18,000. The size, age, and elevation of your home move the number. For a written quote on your specific home, call (350) 305-4609, free.
How much does it cost to install a window where there wasn’t one before?
Cutting a new opening, framing it, adding a header, running new flashing, and installing a window costs $1,800 to $4,000 per opening in West Covina. That includes stucco repair on the exterior and drywall work on the interior. It’s a fundamentally bigger job than a replacement, and you shouldn’t tackle it without someone who does this work daily. Call (350) 305-4609 to talk through whether an opening makes sense for your floor plan.
Can you install windows the same day?
Yes. Standard replacement jobs with in-stock vinyl windows can often be completed same-day in West Covina. Custom sizes, impact-rated glass, and second-story work may require a second day. When we give you a quote, we give you a schedule too. Call (350) 305-4609 for availability.
What’s the labor cost to install a window in West Covina?
Labor runs $100 to $300 per window for a straightforward retrofit into an existing opening. Full-frame replacement or new-construction installation runs $250 to $550 per window in labor. Complex access, rot remediation, or custom trim work adds from there. Our estimates break out labor and materials separately, so you’ll see exactly what you’re paying for. Call (350) 305-4609 for a free line-item quote.
How much do impact windows cost in West Covina?
Impact-rated windows (built to resist wind-borne debris without shattering) run $800 to $2,200 per window installed in West Covina, depending on brand and frame material. PGT vinyl starts around $800; ES Windows and CGI aluminum push past $2,000 on larger units. These windows also bring a side benefit: they cut outside noise noticeably, which matters if you live near the 10 or the 57. We carry five impact-rated lines. Call (350) 305-4609 for a quote.
Why do West Covina window prices vary so much between companies?
Because window quality, installation standards, and warranty coverage are not the same across the board. A $400 window with shoddy flashing will rot your framing in five years. A $1,000 window installed to manufacturer spec with a written 365-day parts-and-labor guarantee is the better deal long-term. We tell clients to compare written line items, not headline numbers. Juniper Windows West Covina puts every dollar in writing before any work starts, and backs every install with the 365-Day Done Right Promise. Call (350) 305-4609 for a free written estimate.

Our name comes from a hardy evergreen that handles sun, wind, and cold without complaint, which is a fitting standard for what windows and doors have to endure.

So we don’t. Every project gets a written price before a single screw turns. If something is wrong with the work in the first year, parts and labor are covered, in writing, for 365 days. That includes a free second visit if a repair fails. No charge, no argument.
