How Much Does Window Replacement Cost in Pasadena?

Window Replacement in Pasadena typically costs $650 to $1,850 per window including installation, with most full-home projects of 10 to 15 windows landing between $8,000 and $22,000. Entry-level vinyl double-hungs start around $450 installed, while impact-rated or custom fiberglass windows in historic Bungalow Heaven homes can exceed $2,800 each.

Those are real numbers from our 2026 project logs across Pasadena, Altadena, and South Pasadena. Your exact price depends on window count, material, glass package, and whether we’re dealing with stucco, wood siding, or brick veneer. We write every quote down before work starts, so you’ll see the number on paper before a single screw turns.

Window Replacement Cost Breakdown (2026)

Here’s what homeowners in Pasadena are paying this year, broken down by window type and material. These ranges include labor, basic trim work, and haul-away of old windows.

These are all-in figures: the window unit, installation labor, flashing, insulation around the frame, interior trim, and disposal of the old sash and frame. We don’t quote a “window only” price and then surprise you with labor charges at the end.

What About Full-Home Projects?

Most Pasadena homes have 10 to 20 windows. Here’s what that looks like in practice:

• Small bungalow (8-10 windows): $6,500 – $14,000
• Mid-size home (12-18 windows): $10,000 – $24,000
• Large home or hillside property (20+ windows): $16,000 – $40,000

Homes in neighborhoods like Madison Heights or Linda Vista with original wood windows often require more trim work, which pushes labor higher. Newer stucco homes are faster to work with and tend to sit at the lower end of these ranges.

What Affects Window Replacement Pricing in Pasadena

• Window material. Vinyl is the most economical. Fiberglass runs about 40% more but handles Pasadena’s summer heat expansion better. Wood-clad windows are the priciest, and Craftsman-era homes in Bungalow Heaven often need custom wood exteriors to satisfy historic district requirements.
• Glass package. Standard dual-pane Low-E glass is included in most quotes. Upgrading to triple-pane or adding argon gas fill adds $80 to $200 per window. In Pasadena, where summer afternoons routinely hit 95°F, a lower solar heat gain coefficient makes a measurable difference in cooling bills.
• Impact-rated glass. Homes in the foothill areas north of the 210, particularly in the Eaton Canyon-adjacent neighborhoods, increasingly need impact-rated glass built to resist wind-borne debris without shattering. Expect that upgrade to add $350 to $700 per window. It’s not optional for some insurance policies anymore.
• Frame condition and retrofit work. If the existing frame is rotted, warped, or out of square, we’re doing more than a swap. New construction windows with nailing fins require cutting back stucco or siding, which adds $150 to $400 per opening. Older Pasadena homes with original 1920s framing often need this.
• Permit requirements. Pasadena’s building department requires permits for window replacement when openings are resized or structural headers change. Standard same-size retrofits usually don’t need permits, but egress changes do. Permit fees run $150 to $450, and we handle the paperwork.
• Window size and accessibility. A second-story window that needs scaffolding or a ladder lift costs more than a ground-floor unit. Same with oversized picture windows that require two or three technicians to set safely.

How to Save on Window Replacement

You don’t have to gut your budget to get good windows. Here’s what we tell Pasadena homeowners who want to spend wisely:

• Replace in phases. Start with the hottest rooms: west-facing bedrooms, living rooms that bake in afternoon sun. Then do the rest over 12 to 24 months.
• Choose vinyl where it counts. Modern vinyl windows from PGT and ECO Window Systems perform well in Pasadena’s climate without the fiberglass price tag. You can save $300 to $500 per window and still get Low-E glass and solid warranties.
• Don’t downsize the opening. Keeping the same rough opening avoids structural work, header changes, and permits. Retrofit installations cost noticeably less than new construction.
• Bundle windows and doors. If you’re replacing a patio door or entry door anyway, doing it all in one project saves on mobilization, haul-away, and scheduling. Juniper installs Therma-Tru entry doors and ViewLux patio doors alongside window work.
• Ask about glass options before you upgrade. Triple-pane is nice, but many Pasadena homes do fine with quality dual-pane Low-E. Save the premium glass for south- and west-facing exposures where the heat gain is real.

Is It Worth Replacing Windows on an Older Pasadena Home?

Short answer: yes, especially if your windows are original single-pane units from the 1920s through 1960s. Pasadena’s temperature swings, from 40°F winter nights to 100°F summer afternoons, stress old windows hard. Single-pane glass with worn weatherstripping loses heat in winter and lets heat pour in during summer. We’ve measured 20°F temperature differences between the glass surface and the room in old Craftsman homes.

Replacement windows with Low-E coatings and insulated frames typically cut heat transfer by 40% to 60% compared to original single-pane units. That translates to lower cooling costs from June through October, when Pasadena Water and Power rates climb with the temperature.

Historic District Considerations

Homes in Bungalow Heaven Landmark District and parts of Madison Heights have design review requirements. You may need wood exterior windows or specific divided-light patterns that match the original character. That pushes pricing toward the higher end of our table, but it’s not optional if you’re in a designated historic zone. We’ve done enough work in these neighborhoods to know what the city’s design review board looks for, and we spec windows accordingly from the start.

Vinyl vs. Fiberglass vs. Wood: What Pasadena Homeowners Should Know

Most of our Pasadena customers choose between three materials. Here’s the practical difference:

Vinyl

Vinyl is the workhorse. It doesn’t rot, doesn’t need painting, and modern vinyl extrusion resists the UV exposure that Pasadena dishes out. PGT and ECO Window Systems both make vinyl lines that hold up well in our climate. Expect to pay $450 to $950 per window installed. The trade-off: vinyl frames are thicker than fiberglass, which means slightly less visible glass area for the same opening.

Fiberglass

Fiberglass expands and contracts at nearly the same rate as glass, so it’s exceptionally stable over decades. It can be painted any color, which matters for historic district compliance. Fiberglass runs $900 to $1,500 per window installed. It’s the premium choice for homeowners planning to stay in their Pasadena home long-term.

Wood and Wood-Clad

Full wood windows are rare for replacements here, mostly because Pasadena’s dry summers and occasional Santa Ana winds punish exposed wood. Wood-clad combines a wood interior with a vinyl or aluminum exterior. For Bungalow Heaven and other historic areas, wood interior with aluminum exterior is the standard. Budget $1,100 to $2,200 per window installed. The wood interior gives you that warm Craftsman look; the exterior cladding means you’re not painting every five years.

What Makes Juniper Windows Pasadena Different

We’re the window and door specialist inside the Relay Home Co. family, and we’ve been doing this since 2001. Sean Mackey runs the Pasadena team, and his standard is simple: every job gets a written price before a single screw turns. No vague ranges that change at the door, no surprise line items on the final invoice.

Here’s what that looks like when you book with us:

• A written price before work starts. Not a verbal estimate, not a “we’ll see how it goes.” A number, on paper, covering the full scope.
• The 365-Day Done Right Promise. If it’s not done right, we make it right, for a full year after installation. Parts and labor, in writing, on every project.
• The Relay Visibility Guarantee. You get a live arrival time you can track, before-and-after photos of every window, and a digital invoice you can pay from a link. Same transparency you’d expect from a rideshare app, applied to your home.
• Background-checked, uniformed technicians. You’ll know exactly who’s walking through your door, with a name and a face before they arrive.
• A live person answers the phone 24/7. Call at 2 a.m. with a broken window and a cold draft, and you’ll talk to a human, not a voicemail tree.

We carry eight product lines: PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux. That matters because the right window for a South Arroyo bungalow is different from the right window for a 1960s ranch in Hastings Ranch. We spec from what fits your home, not from whatever’s left in a warehouse.

Frequently Asked Questions: Window Replacement Cost in Pasadena

How much does it cost to replace 10 windows in Pasadena?

Replacing 10 standard vinyl double-hung windows in Pasadena typically costs $6,000 to $9,500 including installation. If you’re choosing fiberglass or wood-clad windows, expect $9,000 to $15,000 for the same count. Call (626) 657-5977 for a written quote on your exact window sizes and material.

What is the cheapest window to replace?

Single-hung vinyl windows are the most affordable, running $450 to $800 per window installed in Pasadena. They’re a practical choice for rental properties, garages, or rooms where you want solid performance without paying for premium features. Keep in mind that double-hungs, which allow both sashes to tilt in for cleaning, cost only about $100 more per window and are the more common choice.

How much does an impact window cost in Pasadena?

Impact-rated windows, which are built to resist wind-borne debris without shattering, run $1,200 to $2,800 per window installed in Pasadena. The premium over standard glass covers laminated interlayers and heavier frames. Homes in foothill areas north of the 210, especially near Eaton Canyon, increasingly need impact-rated products for insurance compliance. Call us for a quote on your specific elevation and exposure.

Is it cheaper to repair or replace windows?

In Pasadena, repairing a single window, like replacing a broken sash or failed seal, runs $150 to $450, while full replacement runs $650 to $1,850 per window. If your windows are more than 20 years old or you have multiple failing units, replacement usually makes more financial sense than patching. We’ll give you an honest recommendation on a free estimate call: (626) 657-5977.

Can you replace windows the same day in Pasadena?

Most standard window replacements are installed same-day once the units arrive, which is typically 2 to 4 weeks after ordering. In-stock vinyl windows from our PGT and ECO lines can sometimes be installed within a week. We handle the measurement, ordering, and installation, and you’ll get a live arrival time on install day through the Relay Visibility Guarantee. Call (626) 657-5977 to check current availability.

How long do new windows last in Pasadena’s climate?

Quality vinyl windows last 20 to 30 years in Pasadena’s climate, while fiberglass windows can last 30 to 40 years. The main enemies here are UV exposure and extreme temperature cycling, which break down seals and warp cheap frames faster than in coastal climates. That’s why we carry products from manufacturers like PGT and ES Windows that engineer for inland Southern California conditions, not Seattle drizzle.
