AfterHow Much Does Windows & Doors Cost in Los Angeles?
Window and door replacement in Los Angeles typically runs between $300 and $1,800 per window and $800 to $4,500 per door, depending on size, glass type, frame material, and the complexity of the opening. Most Los Angeles homeowners replacing a full house of windows spend between $8,000 and $22,000 installed – a wide range that reflects the city’s mix of 1950s ranch homes in the Valley, Craftsman bungalows in Silver Lake, and Spanish-revival construction in Hancock Park, each with its own framing quirks. At TruePane, we quote manufacturer lines side by side on paper so you see exactly what you’re buying before any work begins.
Windows & Doors Cost Breakdown (2026)
The figures below reflect what Los Angeles homeowners are actually paying in 2026 – labor, materials, and standard installation included. They assume a straightforward swap (existing opening, no structural alteration). Prices rise when openings need reframing, when stucco or drywall repair is required, or when custom sizing is involved.
| Product Type | Low End | Mid Range | High End |
|---|---|---|---|
| Single-hung window (vinyl, standard size) | $300 | $550 | $850 |
| Double-hung window (fiberglass or wood-clad) | $550 | $900 | $1,600 |
| Sliding window (aluminum, common in L.A. mid-century builds) | $400 | $700 | $1,100 |
| Casement window (vinyl or fiberglass) | $500 | $950 | $1,800 |
| Picture / fixed window | $350 | $650 | $1,200 |
| Bay or bow window | $1,400 | $2,800 | $5,500 |
| Entry door (steel or fiberglass, prehung) | $800 | $1,800 | $3,500 |
| Entry door (solid wood, custom) | $2,000 | $3,500 | $6,500 |
| Sliding patio door (vinyl, 6 ft) | $900 | $1,600 | $2,800 |
| Sliding patio door (aluminum, 8 ft – popular in L.A. indoor-outdoor builds) | $1,200 | $2,400 | $4,500 |
| French door (interior or exterior, pair) | $1,400 | $2,600 | $4,800 |
| Impact-rated window (PGT, CGI, or ES Windows) | $900 | $1,600 | $3,000 |
| Impact-rated entry door | $1,800 | $3,200 | $5,500 |
| Full-house window replacement (10-15 units, average L.A. home) | $8,000 | $14,000 | $22,000 |
A few things push those numbers in either direction. Stucco exteriors – which cover the majority of homes in Los Feliz, Koreatown, and much of the Eastside – add $150 to $400 per opening for cut-and-patch work that a proper install requires. Second-story work adds a modest labor premium. And because Los Angeles sits in a seismically active region, some older homes in neighborhoods like Highland Park or Chatsworth need header reinforcement before a larger opening can take a new unit – that’s a separate carpentry line item that a thorough estimator will flag upfront, not after demo day.
What Affects Windows & Doors Pricing in Los Angeles
- Glass package and energy rating: California’s Title 24 energy code requires a minimum U-factor and solar heat gain coefficient (SHGC) for replacement windows in Los Angeles County. Low-e dual-pane glass that meets those thresholds typically adds $80 to $180 per unit over standard clear glass – but it’s not optional for permitted work. Triple-pane is available from lines like Andersen and Marvin, and makes sense for rooms on the west or south face of a home in the San Fernando Valley where afternoon heat load is significant.
- Frame material: Vinyl frames are the most common choice in Los Angeles because they don’t warp or corrode in coastal air (particularly relevant for homes in Playa del Rey or Marina del Rey). Fiberglass holds paint better and is dimensionally stable. Wood-clad frames from lines like Pella or Marvin cost more but match the character of pre-war Craftsman and Colonial homes in Pasadena and South Pasadena precisely. Aluminum frames, ubiquitous in mid-century builds across the Valley, are typically the least expensive but carry a thermal penalty unless they’re thermally broken.
- Opening condition and site complexity: A pocket replacement (insert into existing frame) is faster and less disruptive than a full-frame tear-out. Homes in older parts of Los Angeles – particularly pre-1960 construction in Boyle Heights or Echo Park – often have wood framing that has shifted, settled, or rotted at the sill, which adds repair time. Out-of-square openings require custom shimming and, in some cases, frame modification.
- Permit requirements: The City of Los Angeles requires a permit for structural changes to window openings and for most full exterior door replacements. The Los Angeles Department of Building and Safety (LADBS) permit fee for residential window work runs roughly $100 to $300 per permit, depending on scope. Like-for-like replacements that don’t alter the opening size are sometimes exempt, but the rules vary by jurisdiction – unincorporated L.A. County operates under slightly different thresholds than the City. We pull the correct permits and handle the inspection schedule on your behalf.
- Manufacturer line and lead time: Milgard, which manufacturers locally and has strong distribution in Southern California, typically ships faster than East Coast lines. Custom colors, grilles, or non-standard sizes on lines like Andersen 400 Series or Marvin Elevate can add two to six weeks to lead time, which affects scheduling. We carry quotes from more than a dozen manufacturer lines so you can weigh cost against wait time on paper.
- Number of units and project scope: Replacing eight or more windows in a single visit almost always carries a better per-unit cost than doing them one at a time. Labor is the primary driver – the crew mobilizes once, measures once, and completes cleanup once. Homeowners in Los Angeles who have deferred maintenance on a full house of original single-pane aluminum sliders often find a full replacement project priced more attractively per window than they expected.
How to Save on Windows & Doors in Los Angeles
The most reliable way to control cost is to get more than one quote – but to compare them on the same basis. A quote that omits stucco repair, permit fees, or haul-away is not a lower price; it’s a deferred surprise. Ask every contractor to itemize those line items explicitly. At TruePane, that’s standard practice: upfront pricing with no items that appear on the bill but not the quote.
Time your project. January through March tends to be the slowest season for window and door work in Los Angeles. Contractors are more available, lead times from some manufacturers are shorter, and scheduling a full-house project in that window (no pun intended) often results in a more attentive crew and tighter timelines than the summer rush.
Bundle the work. If you’re replacing windows, consider whether any exterior doors need attention in the same pass. The cost-per-opening drops when the crew is already there, the permit is already open, and the stucco patch is already on the schedule. We regularly save Los Angeles homeowners $600 to $1,200 on a combined window-and-door project versus two separate mobilizations.
Check utility rebates. Southern California Edison and SoCalGas both run residential energy efficiency rebate programs that have, in past years, offered $50 to $200 per qualifying window installation. Program terms change, so verify current availability at the time you’re ready to schedule – but it’s worth a ten-minute check before you sign anything.
Ask about standing discounts. TruePane offers a free written repair estimate, an maintenance check, and a permanent 5% discount for seniors and veterans – no coupon required, just mention it when you call. For homeowners 55 and older who’ve been in the same Los Angeles home for twenty-plus years, that senior discount is applied automatically.

FAQs – Windows & Doors Cost in Los Angeles
How much does a single window replacement cost in Los Angeles in 2026?
A single window replacement in Los Angeles runs $300 to $1,800 installed, depending on size, frame material, and glass package. A standard vinyl single-hung in a typical San Fernando Valley ranch home sits closer to $400 to $600. A wood-clad casement in a Craftsman bungalow in Altadena runs $900 to $1,500. Those ranges include labor, standard hardware, and haul-away – stucco repair and permits are separate line items if applicable. Call (888) 635-0804 for an exact quote on your opening; the estimate is free.
Is it cheaper to repair or replace a window in Los Angeles?
Repair costs $150 to $450 for most common issues – failed seals, broken hardware, worn weatherstripping. If the frame is structurally sound and the glass failure is isolated, repair is almost always worth it. But if your windows are original single-pane aluminum sliders from the 1960s or 1970s (common throughout the Valley and older parts of the Westside), the math usually favors replacement: energy savings on cooling alone in a Los Angeles summer can offset the cost in three to five years, and modern dual-pane units meet Title 24 requirements that originals cannot. We’ll tell you honestly which direction makes sense – we’re not in the business of replacing windows that don’t need replacing. Call (888) 635-0804 and we’ll walk through it with you.
Does Los Angeles require a permit for window replacement?
Los Angeles requires a permit for structural window work and for most full exterior door replacements – the LADBS permit fee runs $100 to $300 for most residential scopes. Like-for-like replacements that don’t change the opening size are sometimes exempt under City of Los Angeles rules, but jurisdiction matters: unincorporated L.A. County, Santa Monica, and Burbank each have slightly different thresholds. We determine the permit requirement for your specific address and pull it on your behalf. No homeowner should be guessing at this.
How much does a sliding patio door replacement cost in Los Angeles?
A sliding patio door replacement in Los Angeles runs $900 to $4,500 installed, with the wide spread driven almost entirely by size and frame material. A standard 6-foot vinyl slider runs $900 to $1,600. An 8-foot thermally broken aluminum slider – the kind that fits the indoor-outdoor lifestyle built into most post-1980 L.A. construction from Encino to Culver City – runs $2,000 to $4,500. Pocket replacement into an existing frame is on the lower end; full-frame removal with stucco repair pushes toward the top. Call (888) 635-0804 for a free same-day estimate.
Can TruePane complete a window or door replacement in a single visit?
Most standard replacements are completed in a single day – sometimes a single morning. A typical 10-window project on an average Los Angeles home takes one crew one full day. Larger scopes, custom units with longer lead times, or projects requiring structural framing may span two visits, but we tell you that upfront in the quote, not after demo starts. Both warranty layers are registered before the truck leaves the driveway, and the Done Right Promise covers any callbacks from day one.

What Our Customers Say
"Our bay window had rotted at the sill and two other outfits wanted to talk us into a flat picture window instead. TruePane rebuilt the opening and matched the original look. Neighbors have knocked on the door about it."
- Gene A."Two entry doors. Showed up when they said, second day was a half day like they said, and the painter they recommended confirmed the frames were dead plumb. The financing was explained in actual dollars, not a brochure."
- Janet R."Impact windows on the whole house. They handled the permit, the inspection, and gave me a folder with every approval number for the insurance company. My windstorm premium dropped enough to notice."
