Window Replacement in Pasadena - Free In-Home Measure, Written Price

Trusted Window Replacement for Pasadena Homeowners

Window Replacement in Pasadena costs between $450 and $2,200 per window depending on the frame material, glass package, and whether the opening needs reframing. Juniper Windows Pasadena has installed windows across Pasadena, Altadena, and the San Gabriel foothills since 2001, and we’re the windows-and-doors specialist inside the Relay Home Co. family. Led by Sean Mackey, our crews work one project at a time, and every job gets a written price before a single screw turns. If you’re fighting drafty sashes, fogged glass, or painted-shut frames in a Craftsman bungalow near the Arroyo, call (626) 657-5977 and we’ll get you on the schedule.

We stock and install PGT, CGI, CWS, and ViewLux product lines, which means we can match the architectural character of your home without compromising on thermal performance. And because Pasadena summers push attic temperatures past 140 degrees, we spec windows with the right U-factor and solar heat gain coefficient for each elevation, not just whatever is on the truck.

Energy Efficient Windows

Energy Efficient Windows are replacement units engineered to reduce heat transfer between your living space and the outside air, typically rated by U-factor (lower is better) and solar heat gain coefficient, or SHGC. In Pasadena, where July and August regularly hit triple digits in the foothills, energy efficient windows make the difference between an air conditioner that cycles normally and one that runs all afternoon. Juniper Windows Pasadena installs energy efficient windows for $750 to $1,900 per opening, with the final number depending on the frame material and glass package you choose.

Low-E Glass and Argon Fills

We spec Low-E coatings on nearly every Pasadena job because the sun here is relentless. Paired with an argon or krypton fill between the panes, this combination drops a window’s U-factor from around 0.50 to 0.27 or lower. You’ll feel the difference on the south-facing side of your house before you see it on the utility bill.

Frame Material and Thermal Breaks

Vinyl frames with internal thermal breaks outperform old aluminum at roughly the same price point. Fiberglass and composite frames cost more but hold their shape across Pasadena’s hot-cold swing without warping. We walk you through the numbers honestly, including when a cheaper window will actually serve your house fine.

Window Repair

Window Repair covers the mechanical and structural fixes that keep your existing windows operating: balance systems, hinge replacements, weatherstripping, track realignment, and sometimes glass replacement within the original frame. If a window won’t stay up or a crank grinds to a stop, you need repair, not a full replacement. Juniper Windows Pasadena completes most window repairs in Pasadena for $175 to $700 per window, and every repair carries the ability for a no-charge follow-up visit if the same issue returns.

Balance and Spring System Repair

Double-hung windows rely on hidden balances to hold the sash at any height. When a balance snaps, the sash slams shut or won’t lift at all. We replace balances in pairs so both sides of the window wear evenly and operate smoothly.

Hardware and Track Realignment

Sliding windows and patio doors drift out of square over time, especially in older Pasadena homes where foundations settle into the clay soil. We reset rollers, lubricate tracks, and replace bent or stripped hardware so the window closes flush and locks without force.

Window Replacement Company

A Window Replacement Company is a contractor that specializes in removing old windows and installing new ones, rather than doing general remodeling or scattered handyman work. Juniper Windows Pasadena is exactly that; we don’t do kitchens, bathrooms, or roofing. Our entire operation is windows and doors, which is why we can offer fixed written pricing on window replacement in Pasadena ranging from $450 for a basic vinyl single-hung up to $2,200 for a large impact-rated picture window with a premium frame.

What Specialization Gets You

Because we install windows five days a week, our technicians can spot framing rot, out-of-square openings, and broken moisture barriers before they become change orders. That’s the benefit of hiring a company that doesn’t split its attention. You get the right flashing detail and a cleaner interior trim line because we’ve done it thousands of times.

Written Pricing, Every Time

Every proposal we hand to a Pasadena homeowner is a written, line-item price, finalized before the install date. The number on that sheet is the number you pay, covered by our 365-Day Done Right Promise in writing. No estimate that morphs into a surprise invoice at the door.

Window Glass Replacement

Window Glass Replacement swaps the insulated glass unit, or IGU, inside an existing frame without replacing the whole window. It’s the right fix when the frame and hardware are in good shape but the glass itself is cracked, fogged, or scarred. Juniper Windows Pasadena charges $250 to $700 for window glass replacement in Pasadena, with the range driven mainly by glass size, Low-E coating, and whether the unit is tempered or impact-rated.

Fogged and Failed Insulated Units

When the seal on a double-pane IGU fails, moisture creeps in and the glass fogs permanently. That haze means the insulating gas has escaped and the window is working against you. We order replacement IGUs to fit the exact glass pack dimensions, so the new unit drops cleanly into your existing sash.

Impact-Rated Glass Upgrades

For homes in the Pasadena foothills near the burn scar zones, we can upgrade glass packages to impact-rated units built to resist wind-borne debris without shattering. It’s a smaller job than full window replacement but delivers a meaningful jump in safety and noise reduction. Ask Sean Mackey directly whether your current frames can accept the thicker glass pack.

Window Sash Replacement

Window Sash Replacement replaces the moving part of the window; the frame that holds the glass, while leaving the outer window frame in the wall untouched. You need it when a sash is rotted, warped, or so compromised that installing new glass alone would be throwing money after a failing structure. Juniper Windows Pasadena prices window sash replacement in Pasadena from $350 to $900 per sash based on size and frame material.

Rotted Wood Sash Replacement

Pasadena’s older Craftsman and Spanish Revival homes often have beautiful original trim but water-damaged sash bottoms. We can fabricate a replacement sash that matches the original profile and sightlines so the window looks right from the curb. The new sash gets a proper paint-grade or stain-grade finish before it goes in.

Vinyl and Composite Sash Swaps

On newer vinyl windows, sash replacement is usually a clean remove-and-replace of the same manufactured profile. We order from the original maker whenever possible, which preserves the fit, the finish, and any remaining manufacturer warranty. If the original line is discontinued, we match the opening precisely with an equivalent from our product lines.

Window Glass Repair

Window Glass Repair addresses minor glass damage before it turns into a full IGU replacement: small cracks, chips, and seal damage at the edge of the pane. In some cases a glass repair can be done same-day; in others it’s the right first step to prevent a crack from spreading through the entire lite. Juniper Windows Pasadena handles window glass repair in Pasadena starting around $150 for a simple chip repair and ranging up to $500 when glass replacement within the frame is required.

Chip Repair Versus Replacement

A shallow surface chip can often be stabilized with resin injection, especially on the outer pane. But a crack that reaches the edge of the glass means the structural integrity is compromised and the entire lite should come out. We’ll tell you straight which situation you have and won’t sell a repair that won’t last.

Tempered Glass Handling

Windows near doors, in bathrooms, and in sidelights are almost always tempered, which means they can’t be cut on site. We order tempered lites to spec from our suppliers and swap them in with the right glazing and setting blocks. Working with tempered glass isn’t a homeowner-level fix; we handle it with proper tooling and gloves.

Window Pane Replacement

Window Pane Replacement is the straightforward replacement of a single pane of glass within a window, most common in older single-pane homes that haven’t been upgraded to double-pane IGUs yet. If you have a cracked pane in a wood-framed window and the rest of the window is sound, you don’t need a whole new window. Juniper Windows Pasadena does window pane replacement in Pasadena for $150 to $450 per pane, including glazing, setting, and cleanup.

Single-Pane to Double-Pane Considerations

Replacing one pane in an old single-pane window is cheap, but the window will still leak energy all year. We’ll show you the honest math: the cost to replace the pane now versus the long-term savings of upgrading to an energy efficient window later. If the budget says pane now, we do the pane now and document the rest.

Historical Window Pane Matching

Pasadena has strict preservation expectations in neighborhoods like Bungalow Heaven and the Prospect Historic District. We can source glass with the slight wave and thickness of period-appropriate material so a replacement pane doesn’t scream “new” next to its neighbors. The glazing putty gets tooled to match the original profile.

Window Seal Repair

Window Seal Repair restores the weather-tight barrier between the glass, the frame, and the outside air when original seals have degraded, shrunk, or pulled away. A failed seal is the quiet culprit behind condensation between panes, drafts you can’t trace, and windows that rattle in their tracks on windy days. Juniper Windows Pasadena performs window seal repair in Pasadena for $175 to $500 depending on whether we’re replacing glazing beads, installing new weatherstripping, or resealing the unit to the frame.

Weatherstripping and Compression Seals

Older Pasadena homes often have double-hungs where the original felt or rubber weatherstripping long ago flattened into nothing. We replace compression seals with modern EPDM or silicone bulb gaskets that hold their shape through hot summers and cool winters. The difference in road noise alone is noticeable, especially near the 210 and 134 corridors.

Structural Seal and Glazing Bead Repair

For fixed and picture windows, the structural silicone seal is what holds the glass in place. When that seal fails, you get water intrusion at the sill and the glass begins to move. We pull the glazing bead, clean the old silicone, and re-bed the glass with fresh sealant applied to the maker’s spec.

Brands We Service

Juniper Windows Pasadena installs and services ViewLux and PGT window lines, and our crews work regularly with CWS and CGI products on larger renovation projects. ViewLux is a favorite for Pasadena homeowners who want slim sightlines and contemporary aesthetics without sacrificing thermal performance. We know their hardware, their glazing options, and their quirks, because we install them every month, not once a season.

PGT and CGI are our go-to lines for impact-rated windows, the kind built to take a wind-borne 2×4 without shattering. CWS rounds out the line card for mid-century and custom-shape work. Whether you have any of these brands, or a window from another manufacturer entirely, we can give you an honest read on repair versus replacement, and we’ll never steer you toward a full replacement when a targeted fix is the smarter money.

Signs You Need a Pro Right Now

• Condensation between the panes. Fog or droplets trapped inside a double-pane window mean the seal has failed and the insulating gas is gone. The window still looks fine from the outside, but it’s now conducting heat like a single pane and will only get worse.
• Windows that won’t stay open or closed. A sash that slams shut or creeps down on its own has a failed balance or a stripped crank. That’s a mechanical failure, and forcing it will damage the frame and the track.
• Visible water stains or soft wood at the sill. Water intrusion around the window opening points to a broken seal or bad flashing. In Pasadena’s clay-heavy soil, settled foundations make this worse, and rot moves fast once it starts.
• A crack that runs to the edge of the glass. Edge cracks compromise the structural strength of the entire lite. On double-pane units, the crack will eventually let moisture into the IGU and turn a repair into a replacement.
• Drafts you can feel from across the room. If you can feel outside air on your hand three feet from a closed window, the weatherstripping is gone or the frame has warped. You’re heating and cooling the Pasadena air, not your living room.
