AfterHow Much Does New Window Installation Cost in Los Angeles?
New window installation in Los Angeles typically runs $650 to $1,450 per window installed, with a whole-house project (10 to 15 windows) landing between $7,500 and $19,500. A single standard vinyl double-hung window replacement usually comes in around $750 to $1,100, while a large custom picture window or a wood-clad unit can push past $2,000. Those numbers include the window, the labor, haul-away of the old unit, and finish work around the frame.

New Window Installation Cost Breakdown (2026)
Here’s what Los Angeles homeowners actually pay across the categories that make up a window project. These ranges reflect 2026 pricing for this market, including materials and installation labor. Your exact figure depends on window count, glass package, and how much framing or stucco repair the opening needs.
| Line Item | Typical LA Range (Installed) |
|---|---|
| Standard vinyl double-hung window | $650 – $1,000 |
| Vinyl single-hung window | $600 – $900 |
| Vinyl slider / horizontal roller | $700 – $1,150 |
| Casement or awning window | $850 – $1,400 |
| Fixed picture window | $550 – $1,000 |
| Wood-clad or fiberglass premium unit | $1,200 – $2,200 |
| Bay or bow window (per unit) | $2,200 – $5,500 |
| Patio / sliding glass door | $2,400 – $5,800 |
| Low-E glass upgrade (per window) | $80 – $260 |
| Full-frame replacement (vs. insert) | +$150 – $400 per window |
| Stucco repair around opening | $75 – $300 per window |
| Permit for structural/egress changes | $200 – $600 |
| Old window removal and haul-away | $40 – $90 per window |
On a 12-window house in a neighborhood like Sherman Oaks, a standard insert replacement with low-E glass commonly comes in around $9,000 to $14,000. Swap in wood-clad units or add two patio doors and the project climbs past $25,000 fast. Full-frame work (where we pull the whole old frame instead of setting the new window inside it) adds roughly 20 to 30 percent because the opening has to be rebuilt and finished. That’s the big fork in the road on most bids, and it’s the first thing we check on site.
What a Written Price Covers
When we put a number on paper, it includes windows, standard installation labor, old-unit haul-away, and cleanup. It also includes the option for a free second visit if anything fails within the guarantee period. It does not include structural reframing, glass breakage during removal of a badly rotted frame, or work that requires a city permit for egress. Those get flagged before we start so nothing surprises you later. See our full New Window Installation in Los Angeles page for the process step by step.
What Affects New Window Installation Pricing in Los Angeles
- Window count and project size. Labor doesn’t scale perfectly with volume, so the per-window price drops as you add units. A 15-window job often runs $75 to $125 less per window than a 3-window job.
- Glass package. In Los Angeles, west- and south-facing rooms bake in the afternoon. Upgrading to low-E glass (a thin coating that reflects heat while letting light through) or adding a second pane with argon fill adds roughly $80 to $260 per window but cuts cooling load measurably in the San Fernando Valley.
- Frame material. Vinyl is the most cost-stable option. Fiberglass and wood-clad cost more up front but hold up longer under LA’s UV exposure, especially near the coast where salt air does its own work.
- Operation type. Sliders and casements cost more than single-hungs because they have more moving hardware. A casement in a hillside home with big swing clearance needs careful spec’ing.
- Insert vs. full-frame replacement. If your existing frame and sill are sound, an insert replacement (the new unit fits inside the old frame) saves $150 to $400 per window. If the frame is rotted, we have to go full-frame, and that number changes.
- Permits and HOA rules. The City of Los Angeles requires permits for certain egress and structural changes. Some HOAs in Pasadena, Santa Monica, and the hillside communities around Encino restrict window color and grid patterns, which can narrow your product choice and affect cost.
- Access and floor level. Second-story work, tight side yards, and hillside lots with steep grade add labor and equipment time. A window at ground level on a flat lot is the cheapest thing we install.
What Drives Price Up or Down in the LA Market
A few things hit differently here than they do in most metros.
Coastal salt air accelerates frame wear. In Long Beach, Redondo Beach, and Santa Monica, aluminum frames from the 1970s are often corroded at the sill. That pushes homeowners toward vinyl or fiberglass and sometimes forces stucco repair around the opening, which tacks on $75 to $300 per window.
Valley heat demands better glass. Homes in Woodland Hills, Northridge, and Chatsworth regularly see afternoon temps 10 to 15 degrees higher than the coast. The low-E investment pays back faster there than anywhere else in the county, so it’s the upgrade we push hardest when we’re in the Valley.
Old single-pane stock is everywhere. A huge share of LA’s housing was built between 1920 and 1970, and much of it still has original single-pane wood windows. Those units are leaky and often have failed sills. We see this constantly in Bungalow-era homes around Highland Park and Eagle Rock. The good news: replacement windows cut both noise and heat, and many homeowners notice the difference in the first month.
Hillside access adds cost. If your home sits on a slope in Silver Lake or Mount Washington, we may need scaffolding or special rigging. That’s labor you can’t skip, and it’s never a surprise on our quote because we walk the property before we price it.
Earthquake-era anchoring matters. We anchor and shim every unit to California’s seismic expectations, and we don’t cut corners on flashing. Cheap installs fail at the flashing first, and that’s where water intrusion starts.
How to Save on New Window Installation
You don’t have to chase the lowest bid to save money. Here’s what actually moves the number:
- Replace in one project, not room by room. Bundling 10 or more windows drops the per-window labor price meaningfully. Staging the job across three years costs more in the end.
- Use insert replacement where the frame is sound. We check the frame first. If it’s solid, you skip the full-frame rebuild and save $150 to $400 per window.
- Choose vinyl for the back of the house, upgrade the front. Nobody cares what the kitchen window is made of. Put the money where it shows.
- Ask your utility about rebates. LADWP has offered energy-efficiency incentives in past cycles for qualifying glass upgrades. We’ll tell you what qualifies when we quote.
- Time it around the shoulder seasons. Spring and fall are our busiest months. Scheduling in the off-season can mean faster turnaround and less scheduling pressure on you.
- Get the price in writing before you commit. A written quote is the single best protection against scope creep. That’s a standard we hold on every job, not a favor.
One more thing worth doing: get two or three estimates. Not to find the cheapest, but to see who shows up on time, answers their phone, and puts a number on paper. That tells you more about a contractor than any review. If you want ours, call (817) 686-2228. Estimates are free and there’s no pressure to book.

- Written price before work starts on every job, with no moving at the door.

FAQs – New Window Installation Cost
How much does new window installation cost in Los Angeles in 2026?
Most single-window replacements run $650 to $1,450 installed, and a full-house project of 10 to 15 windows typically lands between $7,500 and $19,500. Bay windows, wood-clad units, and patio doors push the number higher. Call (817) 686-2228 for an exact quote on your home. Estimates are free.
Is it cheaper to repair or replace my windows in Los Angeles?
If it’s one failing sash or a bad hinge, repair usually runs $150 to $450 and beats replacement. If you have three or more failed units, rotted frames, or single-pane glass throughout the house, replacement wins on cost over the long run. A full-frame replacement on a rotted window runs $1,000 to $2,200, whereas patching around rot tends to fail again within a few years. We’ll tell you honestly which way makes sense after we look. Call (817) 686-2228 to set up a free assessment.
Can you install new windows the same day?
Single-window replacements often finish in 2 to 4 hours, and a full-house project of 10 to 15 windows typically takes 1 to 2 days. Same-day full-house installation isn’t realistic with quality work, but we don’t drag projects out either. Call (817) 686-2228 and we’ll give you a real timeline based on your window count.
Do I need a permit to install new windows in Los Angeles?
Straight replacements in the same opening usually don’t require a permit. If you’re changing the opening size, converting a window to a door, or affecting egress in a bedroom, the City of Los Angeles will require a permit, and that typically runs $200 to $600. We flag permit needs before the job starts so it’s never a surprise. Call (817) 686-2228 if you’re unsure which category your project falls into.
Will new windows actually lower my energy bill in Los Angeles?
New low-E windows can cut cooling costs by roughly 10 to 25 percent in homes with original single-pane glass, with the biggest savings in the San Fernando Valley and other inland areas. Coastal homes see a smaller gain on cooling but often notice a real drop in outside noise. The upgrade adds $80 to $260 per window. Call (817) 686-2228 to talk through what makes sense for your house.
How much does a sliding patio door cost installed in Los Angeles?
A standard sliding patio door runs $2,400 to $5,800 installed depending on size, glass package, and frame material. We carry Therma-Tru and other entry and patio systems, and every install includes the same written price and 365-Day Done Right Promise. Call (817) 686-2228 for a quote on your specific opening.
