AfterHow Much Does New Window Installation Cost in Los Angeles?
New window installation in Los Angeles typically runs $850 to $2,400 per window installed, with most single-family homes landing between $1,100 and $1,600 per opening once impact-rated glass and current Title 24 requirements are factored in. A full-house project of 12 to 15 windows generally comes in between $14,000 and $28,000. That range holds whether you’re in a 1920s bungalow in Highland Park or a newer build in Playa Vista, though the details behind the number shift quite a bit from block to block.
Here’s the part most pricing pages skip: in Los Angeles, the window itself is often the smaller half of the bill. Labor, permits, stucco repair, and lead-safe handling on pre-1978 homes routinely account for 40 to 55 percent of what you’ll pay. Understanding that split is the difference between comparing real quotes and comparing hopes.

Key Takeaways
- Typical Los Angeles cost: $850 – $2,400 per window, installed.
- Impact-rated glass adds roughly $150 – $400 per window but can lower insurance premiums.
- Labor and stucco repair are the biggest variables in LA, not the glass.

New Window Installation Cost Breakdown (2026)
These are installed prices for the Los Angeles market, covering materials, labor, disposal of old units, and standard flashing. They reflect real 2026 pricing, not national averages pulled from a different state with a different climate and a different permit desk.
| Line Item | Typical Cost Range | Notes |
|---|---|---|
| Single-hung vinyl, standard size | $850 – $1,250 | Most common replacement in LA |
| Double-hung vinyl | $1,000 – $1,500 | Both sashes operate |
| Casement window | $1,200 – $1,900 | Crank operation, better airflow |
| Sliding glass window | $1,300 – $2,100 | Common in mid-century homes |
| Impact-rated glass upgrade | +$150 – $400 per window | Wind-borne debris resistance |
| Wood or fiberglass frame upgrade | +$300 – $800 per window | Better for historic districts |
| Full-frame installation (vs. insert) | +$250 – $600 per window | Replaces frame and trim |
| Stucco repair and patching | $150 – $500 per opening | Varies with stucco age and texture |
| Lead-safe handling (pre-1978 homes) | $100 – $250 per opening | Required by EPA rules |
| Los Angeles city permit | $150 – $600 total | Based on project valuation |
| Second-story or ladder access | +$100 – $300 per window | Safety and equipment cost |
| Old window removal and disposal | $40 – $90 per window | Usually included in our pricing |
So what actually moves the number? Three things dominate. First, whether it’s an insert replacement (new sash and glass set into the existing frame) or a full-frame replacement (the entire frame comes out). Inserts save money; full-frame fixes the water intrusion that causes most of the rot we find in older Los Angeles homes. Second, the glass package. A basic dual-pane unit and a laminated impact-rated unit are both “dual pane,” and they’re nowhere near the same price or the same product. Third, access. A ground-floor window in a single-story home in Reseda is a straightforward install. The same window on the second floor of a hillside house in Mount Washington is not.
We carry eight product lines – PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux – so we’re never pushing one brand at every house. If a project calls for a specific frame material or a specific U-factor to pass Title 24, we have options on the shelf rather than a single catalog to work from. You can see how we approach the full scope on our New Window Installation in Los Angeles page.
What Affects New Window Installation Pricing in Los Angeles
Los Angeles isn’t a single market. A window quote in Boyle Heights and a window quote in Pacific Palisades can differ by thousands on similar square footage, and it’s rarely about the window. Here’s what drives the spread.
- Permits and Title 24 compliance. California’s energy code sets minimum U-factor and SHGC requirements for replacement windows, and the thresholds differ depending on your climate zone. Los Angeles County spans several zones, so a window that passes in coastal Santa Monica may not meet the number required in the San Fernando Valley, where summer heat pushes cooling loads higher. Your quote should show the rated values, not just claim compliance.
- Impact rating. Much of Los Angeles County sits in or near a wind-borne debris region, and more insurers are asking about impact-rated glass. Laminated impact glass (built to resist wind-borne debris without shattering) adds cost but can reduce your premium. If you’re in a high-fire-severity area, the conversation also shifts toward tempered glass and ember-resistant framing.
- Stucco exterior. Most LA homes are stucco, and stucco doesn’t move politely. Pulling a window out of a stucco wall means cutting back, setting the new unit, then re-floating and re-texturing the patch. Matching a 60-year-old sand float finish takes a craftsman, and it costs more than the caulk-and-go approach some outfits use. In Burbank and Glendale we regularly see three-coat stucco that needs careful feathering to blend.
- Home age and lead paint. Any home built before 1978 triggers EPA lead-safe work practices: containment, wet methods, and proper disposal. It adds $100 to $250 per opening. We built this into our pricing after finding it was the single most common “surprise” line item on competitors’ invoices.
- Historic and HOA restrictions. If you’re in a Historic Preservation Overlay Zone, like parts of Angelino Heights or the Craftsman districts, or you’re in a planned community with design review, the required profile and color can limit which units qualify. That can push you from a standard vinyl frame to a wood or fiberglass one, which is a real cost jump.
- Glass size and shape. Oversized picture windows, arched tops, and anything custom-fabricated cost more than a stock size. Large glass also means heavier units, more crew, and sometimes a crane or a lift. A 6-foot-wide picture window in a Mid-Wilshire condo is a different job than three standard sashes.
One more factor worth naming: who you hire. A quote that’s $400 per window below everyone else is usually missing permit fees, stucco repair, or proper flashing. Those get added back at the door, or they never happen and you find out during the first real rain. That’s exactly the pattern our no-hassle upfront pricing exists to end – a written price before a single screw turns, and it doesn’t change later.
How to Save on New Window Installation
There’s no magic discount that makes windows cheap. But there are real ways to bring a Los Angeles project down without cutting corners on the parts that keep water out.
- Do the worst windows first. If you can’t do the whole house this year, target the north-facing and west-facing openings where condensation and heat gain are worst. Phasing keeps each phase affordable and lets you judge the work before committing to the rest.
- Choose inserts where the frame is sound. If your existing frames aren’t rotted or leaking, an insert replacement can save $250 to $600 per opening versus full-frame. A reputable installer will tell you which frames are worth keeping and which aren’t. We will.
- Bundle the project. Per-window labor drops when the crew is already on site. Fifteen windows in one visit costs meaningfully less per window than five windows across three visits.
- Ask your insurer about impact-rated glass. The upfront cost is higher, but in LA County wind-borne debris zones, the premium credit can offset part of it over time. On a full house, that’s worth asking about before you order.
- Check for utility and efficiency programs. State and utility efficiency rebates for qualifying window upgrades come and go, and the rules change. Ask whoever quotes your job whether anything currently applies. If there’s money on the table, you should know before you sign.
- Get the price in writing before work starts. This is the biggest saver, and it’s not a discount at all. A quote that morphs into a surprise invoice is how most window projects get expensive. We hand you a written price up front and stick to it.

FAQs – New Window Installation Cost
How much does a single window cost to install in Los Angeles?
A single replacement window in Los Angeles costs $850 to $2,400 installed, depending on the type, glass package, and whether it’s an insert or full-frame replacement. A standard single-hung vinyl insert in a one-story home is often around $950 to $1,200. Call (682) 281-2168 for an exact quote on your window – estimates are free.
Is it cheaper to repair or replace a window?
Repair runs $150 to $500 for things like a broken sash, failed seal, or sticky track, and replacement starts around $850 installed. Repair wins when the frame is solid and the problem is isolated. Replacement wins when you’re seeing fog between the panes, water stains around the frame, or rot at the sill – those are signs the whole unit is failing, and patching it just delays the inevitable. Worth noting for LA: a single failed seal on 1960s aluminum is normal. A failed seal plus a soft sill usually means replacement.
Do I need a permit to replace windows in Los Angeles?
Yes, most window replacement in the City of Los Angeles requires a permit, and permit fees commonly run $150 to $600 based on the project valuation. Windows are a structural opening, and the city treats them that way. Replacements that keep the same opening size are simpler than those that change it, but the paperwork still applies. We pull the permits and include the cost in your written quote, so it never shows up as a surprise.
How much do impact windows cost in Los Angeles?
Impact-rated windows in Los Angeles typically add $150 to $400 per window over standard dual-pane, putting a typical impact window in the $1,000 to $2,600 installed range. The glass is laminated to hold together when struck by wind-borne debris. If your insurer offers a premium credit for impact-rated openings, factor that in – it can change the math over the life of the windows.
Can you install new windows in Los Angeles the same day?
Most window installations take 3 to 8 hours per batch of windows, and many single-story jobs finish in one day once the units are on hand. The lead time is usually in ordering the windows, not the install. Because we stock eight product lines, we can often find the right unit faster than a shop working from one catalog. Call (682) 281-2168 and we’ll tell you honestly what your timeline looks like.
