How Much Does Patio Door Installation Cost in Pasadena?
Patio door installation in Pasadena typically costs between $2,800 and $7,500 for a standard sliding glass door, including the door, labor, and basic framing work. Most Pasadena homeowners pay around $4,200 for a mid-grade vinyl or aluminum sliding door with standard glazing. French doors and multi-slide systems run higher, landing between $5,500 and $14,000 depending on size, glass package, and how much structural work the opening requires.
The biggest variables are the door type, the glass you choose, and what the installer finds when the old door comes out. Pasadena’s older housing stock, especially in neighborhoods like Bungalow Heaven, Madison Heights, and the Craftsman pockets north of the 210, often hides rotted framing or non-standard rough openings that add $300 to $900 to the job. We’ll walk through those numbers below so you know what to expect before anyone hands you a quote.

Patio Door Installation Cost Breakdown (2026)
Here’s what we’re seeing across Pasadena, Altadena, and South Pasadena in 2026 for a standard 72-inch by 80-inch opening. These are real project ranges from our install crews, not national averages pulled from a database.
| Line Item | Cost Range | What It Covers |
|---|---|---|
| Basic sliding patio door (vinyl, 72×80) | $1,200 – $2,800 | Entry-level to mid-grade vinyl slider, standard dual-pane glass, basic hardware |
| Mid-grade sliding door (vinyl or aluminum, 72×80) | $2,800 – $5,000 | Better U-factor ratings, low-E glass, upgraded locking, cleaner sightlines |
| Premium sliding door (impact-rated, 72×80) | $4,500 – $8,500 | Impact-rated glass (built to resist wind-borne debris without shattering), reinforced frames, multi-point locks |
| French patio door (two swinging panels, 72×80) | $3,500 – $8,000 | Hinged double doors, more hardware, tighter air sealing, wider view when open |
| Multi-slide or bi-fold door (12-foot opening) | $9,000 – $18,000 | Multiple panels stacking or folding, large structural header often required |
| Labor and installation | $800 – $2,200 | Removal of old door, haul-away, setting the new unit, shimming, sealing, trim work |
| Permit fees (City of Pasadena) | $150 – $450 | Required when the rough opening changes or structural framing is touched |
| Rot repair or framing correction | $300 – $1,200 | Common in pre-1950s homes where the sill or king studs have water damage |
| Stucco or drywall patch after install | $200 – $600 | Repairing the interior and exterior finish around the new door |
What Drives the Price Up or Down
Glass is the single biggest cost lever. Standard dual-pane glass keeps the price low, but Pasadena summers and the Santa Ana season push a lot of homeowners toward low-E coatings and impact-rated glass, which can add $1,500 to $3,500 to a door. Impact-rated units matter more in the foothill neighborhoods, Alta Dena and the Pasadena Glen area, where wind gusts hit harder during Santa Ana events.
Door material matters too. Vinyl is the most affordable and holds up well in Pasadena’s climate. Aluminum costs more but gives you thinner frames and larger glass area, which is why homeowners in mid-century ranches in Hastings Ranch and upper Linda Vista often choose it. Wood doors look right on Craftsman homes in Bungalow Heaven but run $4,000 to $9,000 and need more upkeep.
Then there’s the condition of the rough opening. In our experience across Pasadena, roughly four in ten patio door replacements in homes built before 1960 uncover some degree of rot at the sill or failing flashing. That’s not a scare tactic. It’s a reality of older framing, and it’s part of why we insist on a written price that accounts for what we can see before the old door comes out.
A Note on Pasadena Permits
The City of Pasadena requires a building permit when a patio door replacement changes the rough opening dimensions or requires new structural headers. A direct size-for-size swap generally does not need one, but if you’re converting a window to a door or widening an opening, plan on the permit line item above. Our team handles the paperwork for every permitted job. You don’t chase anything down.
What Affects Patio Door Installation Pricing in Pasadena
- Neighborhood and home age. Bungalow Heaven, Madison Heights, and Garfield Heights are dense with 1920s-to-1940s construction. Non-standard rough openings, old plaster walls, and existing rot are more common there than in the 1980s tracts up by Eaton Canyon or the newer builds near Annandale. Older framing means more labor hours, and labor is $95 to $150 per hour on most Pasadena patio door jobs.
- Glass selection. Dual-pane is the baseline. Add low-E for heat rejection and you’ll pay $400 to $900 more for a standard slider. Step up to impact-rated glass and that jumps to $1,500 to $3,500 above a basic unit. Pasadena’s summer heat makes low-E worth the money for west-facing doors.
- Door footprint. A standard 72×80 slider is a commodity size with commodity pricing. Go wider, taller, or into a custom multi-panel setup and the per-panel price climbs steeply because the frames and glass are fabricated per order, not pulled from stock.
- Structural work. Converting a window into a patio door, removing a load-bearing wall section, or installing a larger header typically adds $1,500 to $5,000. On a 72×80 replacement with no framing changes, you won’t see this cost at all.
- Finish work. Pasadena’s stucco exteriors and lath-and-plaster interiors take longer to patch cleanly than drywall. Expect $200 to $600 for interior and exterior finish repair unless the new door is a true size-for-size swap.
- Disposal and haul-away. Most installers include old-door haul-away in the labor line, but if the old unit contains tempered glass in multiple panels or there’s lead paint remediation involved (common on pre-1978 Pasadena homes), tack on another $150 to $500.
How to Save on Patio Door Installation
The smartest way to control cost is to buy the right door for your house the first time, which means matching the door to the architecture and the climate rather than chasing the cheapest unit on the rack. A few practical levers we tell our Pasadena clients:
- Do a size-for-size swap. If your existing slider is a true 72×80, replacing it with a door in the same footprint avoids framing changes, permit fees, and most finish repair. That keeps the project in the $2,800 to $4,500 range instead of climbing past $7,000.
- Choose vinyl over aluminum unless you need slim frames. Vinyl sliders with double-pane glass deliver solid thermal performance for $1,200 to $2,800 on the unit side. You give up the thinnest sightlines, but you keep a few thousand dollars in your pocket.
- Prioritize low-E glass over impact-rated unless you’re in the foothills. Most Pasadena homes east of the Arroyo don’t require impact-rated glass under current code. Low-E gets you the heat rejection for a fraction of the upcharge.
- Bundle with other openings. If you have a second door or windows you’re planning to replace anyway, doing them in one project spreads the mobilization and haul-away costs across more units. The per-opening labor hit drops meaningfully.
- Get the number in writing before the job starts. A vague estimate that becomes a surprise invoice is the most common way Pasadena homeowners overpay. Every Juniper project carries a written price before a single screw turns, and the 365-Day Done Right Promise covers the installation for a full year after completion, parts and labor, in writing. Call (626) 657-5977 for a free estimate and we’ll give you the same breakdown shown above for your specific door.
Patio Door Types and Their Costs in Pasadena
Sliding Patio Doors
The most common patio door in Pasadena, and for good reason. Sliders don’t swing into the room or the yard, they handle high-use traffic well, and their simple track mechanism means fewer moving parts to maintain. Expect $2,800 to $5,000 installed for a good vinyl or aluminum slider with dual-pane glass. Impact-rated sliders run $4,500 to $8,500 installed.
We install sliders from PGT, CGI, and Therma-Tru, and the difference between a bargain slider and a good one shows up in two places: the U-factor on the glass (lower is better for keeping Pasadena’s summer heat out) and the quality of the rollers and track. Cheap rollers bind after a few years of California dust. Good ones roll clean for a decade or more.
French Patio Doors
French doors, two hinged panels that swing open from the center, run $3,500 to $8,000 installed in Pasadena. They’re the right aesthetic choice for Spanish Colonial Revival homes in the Caltech area, Mission-style houses in San Rafael, and anywhere the architecture calls for individual door panels rather than a wall of moving glass.
French doors offer something sliders can’t: both panels can be opened at once, giving you a full-width opening instead of a half-width one. The tradeoff is swing space. You need clear floor area on both sides of the door for the panels to open, which doesn’t always work in tight Pasadena sunrooms or condos with shallow patios.
Multi-Slide and Bi-Fold Doors
Multi-slide doors, sometimes called stacking sliders, and bi-fold doors fold or stack multiple panels to open a wall almost completely. These are the most expensive option at $9,000 to $18,000 installed for a 12-foot opening, and they almost always require a structural header upgrade.
We see these most often in mid-century glass houses up in the San Rafael Hills and on new renovations in Linda Vista where homeowners want a seamless indoor-outdoor connection to a canyon view. The payoff is dramatic. The price tag is too. But with eight product lines, including ES Windows and ECO Window Systems, we can spec a multi-slide that fits the project without compromising on glass quality or frame performance.
Labor Costs and Timeline in Pasadena
Labor for a standard patio door replacement in Pasadena runs $800 to $2,200 depending on the scope. A clean size-for-size swap takes a two-person crew four to six hours, including haul-away and cleanup. Add framing changes, rot repair, or custom door assembly and you’re looking at a full day or two.
Most Pasadena jobs finish in one day. Multi-slide doors, French doors with sill repair, and any project requiring a permit inspection usually take two to three days from start to final inspection. We schedule the permit inspection before we remove the old door whenever possible, so you’re not left with a tarped opening waiting on the city.
Our crews run background-checked, uniformed technicians, and you’ll know exactly who is walking through your door because the booking system sends a live arrival time before anyone shows up. No four-hour windows. No voicemail queue when you call to check on the status. A live person answers the phone 24/7 at (626) 657-5977.
Why Pasadena’s Climate Affects Your Door Choice
Pasadena gets the double punch: intense summer sun from the west and Santa Ana winds that push dry, gritty air through the foothills in the fall. A patio door with a poor U-factor or uncoated glass turns a west-facing living room into an oven by 3 p.m. in August. That’s not an exaggeration. We’ve measured surface temperatures over 120 degrees on single-pane patio doors in Pasadena in late summer.
Low-E glass, which reflects heat while letting visible light through, cuts that heat gain significantly. For west- and southwest-facing doors, it’s the single best upgrade you can make, adding $400 to $900 to the door cost but paying back in comfort and lower AC loads every summer.
Then there’s the dirt. Pasadena’s dry-season dust and the fine grit that blows through during Santa Ana events work their way into track systems and rollers. Cheap patio door tracks clog and bind. The doors we install through Juniper’s product lines use sealed bearing rollers and elevated track systems designed for exactly this kind of environment. The extra $150 to $400 for a quality track system keeps the door sliding smoothly for years instead of seizing up after two summers.
Energy Efficiency and Pasadena Building Codes
California’s Title 24 energy code sets minimum performance standards for replacement doors, and Pasadena enforces it. A patio door installed in Pasadena must meet specific U-factor and solar heat gain coefficient (SHGC) requirements based on the home’s climate zone. Zone 6 and Zone 8 cover different parts of the Pasadena area, and the requirements roll forward with every code cycle.
What that means for your budget: you can’t legally install a bare-bones single-pane door in Pasadena in 2026. The minimum standard is dual-pane glass with some degree of low-E coating. That’s baked into the pricing we quoted above. Doors that just meet the standard land at the bottom of the range. Doors that exceed it, with U-factors below 0.30 and SHGC values tuned to your home’s orientation, land higher but perform noticeably better.
We spec and install units from PGT, CGI, ES Windows, and the rest of our eight lines with the correct Title 24 compliance for your specific orientation and climate zone. A north-facing door doesn’t need the same glass package as a west-facing one, and matching the glass to the orientation keeps the price honest.
Replacement vs. New Construction Patio Doors
If your existing patio door is in a formed opening, you’re installing a replacement door. If you’re adding a door where one doesn’t exist, or rebuilding the opening entirely, that’s new construction. The cost difference is substantial.
Replacement patio door installation in Pasadena runs $2,800 to $7,500 for a standard slider. New construction installation runs $5,000 to $12,000 or more because it includes cutting a new opening, framing it, installing a header, flashing and waterproofing the new penetration, and finishing both sides. When we convert a window to a patio door in Pasadena, which is a common project in 1950s ranch homes, the framing and finish work usually exceeds the cost of the door itself.
How to Check Your Existing Patio Door’s Condition
Before you replace, check what’s actually wrong. Some patio door problems look worse than they are. If the door sticks, the track may just need cleaning and lubrication. If there’s a draft, the weatherstripping may be shot but the door frame itself is fine. If there’s condensation between the glass panes, the seal has failed and the glass needs replacement, but the frame may still have years left.
Rot is the exception that pushes toward full replacement. Poke the bottom corners of the door frame with a screwdriver in a few places you can’t easily see. If the wood gives, the rot has taken the structural part of the opening and the whole unit should come out. This is the pattern we see over and over in Pasadena’s older neighborhoods, and catching it early usually saves $1,000 or more compared to letting the water intrusion spread into the subfloor.
Because of the way sliding door springs and moving glass panels interact, a heavy patio door panel coming off its track is a genuine safety issue. If your door has jumped its track or the rollers are visibly failing, call a professional rather than wrestling with the panel. A sliding glass door panel can weigh 100 to 200 pounds, and when it falls, it shatters into thousands of sharp tempered-glass pieces. We handle this every week and would rather see you safe than sorry. Call (626) 657-5977 and we’ll send someone.
How Much Does It Cost to Install a Patio Door in Pasadena?
Installing a patio door where none exists is the most expensive version of this project, running $5,000 to $12,000 in Pasadena. That includes cutting the opening, framing and header work, the door itself, flashing and waterproofing, interior and exterior finish, and the permit. The door unit accounts for only 35 to 50 percent of that total. The rest is labor, framing, and finish materials.
Most of these conversions in Pasadena happen on the back wall of a living room or kitchen, replacing a window. The rough opening for a standard 72-inch slider requires a new header sized to carry the wall and roof load above. That’s structural work, not cosmetic, and it needs a permit. We pull permits for these jobs routinely and schedule inspections in a sequence that keeps the project moving.
How Much Does a Patio Door Replacement Cost in Pasadena?
A straightforward patio door replacement, same size, same opening, no structural surprises, runs $2,800 to $5,000 for a standard sliding door installed. That’s the number we give most Pasadena homeowners for a vinyl slider with dual-pane low-E glass, haul-away included, finished and cleaned up.
Add a door from PGT’s impact-rated line or a Therma-Tru French door and the installed price lands at $4,500 to $8,500. Add rot repair, a custom size, or a second floor location with stair access and you’re pushing into the $6,000 to $9,000 range. The table at the top of this page breaks all of that down line by line.
Should You Repair or Replace a Patio Door in Pasadena?
The decision comes down to where the failure is. Here’s the honest guide we give on every estimate call:
- Repair if the rollers are worn but the frame and glass are fine. Roller replacement runs $150 to $400 from a good door tech. It extends the door’s life by years without touching the frame.
- Repair if the weatherstripping is shot but the door seals and operates. New weatherstripping costs $80 to $250 and fixes most drafts.
- Replace the glass if the panes are fogged but the frame is solid. A new dual-pane low-E glass pack for a standard slider runs $400 to $900. Only worth it if the frame and track are in genuinely good shape.
- Replace the door if the frame shows rot, the track is bent or pitted, or the door is leaking around the opening. Once water has gotten into the rough opening, quick fixes just cover up a bigger problem. Full replacement is the honest repair.
If you’re not sure which situation you have, call (626) 657-5977 and describe what you’re seeing. We’ll give you a straight read on it, and if it’s a repair we can’t help with because it’s not in our scope, we’ll tell you that too. No pressure. No upsell. We only install windows and doors.
FAQs – Patio Door Installation Cost
How much does a sliding glass door cost in Pasadena?
A sliding glass patio door in Pasadena costs $2,800 to $5,000 installed for a standard 72×80 vinyl or aluminum unit with dual-pane low-E glass. Premium sliders with impact-rated glass run $4,500 to $8,500 installed. The door unit itself accounts for roughly half of the total; the rest is labor, haul-away, and finish work. Call (626) 657-5977 for a free, no-obligation estimate on your specific door.
Is it cheaper to repair or replace a patio door?
Repair is cheaper when the problem is isolated to rollers, weatherstripping, or a fogged glass pack: $80 to $900 for most repairs in Pasadena. Replacement makes financial sense when the frame has rot, the track is bent, or the door is leaking around the opening: $2,800 to $7,500 installed for a standard replacement. If the frame and glass are good but the door is hard to operate, repair often buys you five or more years. Call (626) 657-5977 and we’ll help you figure out which side of the line your door is on.
How long does patio door installation take in Pasadena?
Most Pasadena patio door replacements are done in one day for a size-for-size swap. That includes removing the old door, hauling it away, setting the new one, sealing, and cleaning up. Jobs that involve framing changes, custom door assembly, or permit inspections take two to three days. We give you a live arrival time before the crew shows up, so you know exactly when the work starts.
Do I need a permit to replace a patio door in Pasadena?
No permit is required for a direct size-for-size patio door replacement in Pasadena. A permit is required when you’re changing the rough opening dimensions, installing a new header, or converting a window to a door. Permit fees run $150 to $450 depending on the scope. Our team pulls permits and schedules inspections for every job that needs them.
What’s the best patio door brand for the money in 2026?
For Pasadena’s climate and price sensitivity, PGT and Therma-Tru deliver the best balance of quality and cost in 2026. PGT’s vinyl and aluminum sliders with low-E glass run $1,400 to $4,000 for the door unit itself, and their impact-rated lines are priced competitively for the protection you get. We carry both brands, plus CGI, ES Windows, and five other product lines, so the right door is always a choice, not a compromise.
Can you install a patio door the same day?
Same-day patio door installation in Pasadena depends on whether the door is a stock size we have in inventory or a custom unit that needs to be ordered.
