AfterHow Much Does Custom Window & Door Order Cost in Los Angeles?
A custom window order in Los Angeles typically runs $850 to $2,800 per window installed, and a custom entry door usually lands between $1,200 and $6,500 installed depending on material, size, and hardware. Whole-home custom orders of 10 to 15 openings generally fall in the $18,000 to $45,000 range. Those numbers include the custom build, delivery, permit coordination, and installation by our crew.
We’re Westlight Windows & Doors, an independently owned and operated Kingswell location serving Los Angeles since 2009. Every price we quote is a written price before any work starts. That’s the first line of the Kingswell Guarantee, and it’s why we put real dollar ranges on this page instead of “call for pricing.”

Custom Window & Door Order Cost Breakdown (2026)
Here’s what the line items actually look like for a Los Angeles custom order. These are installed prices, meaning the window or door, the labor, the disposal of the old unit, and the finishing work are all included.
| Item | Typical LA Range (Installed) | Notes |
|---|---|---|
| Custom vinyl window, standard size | $850 - $1,400 | Single-hung or slider, dual-pane, low-e glass |
| Custom vinyl window, oversized or arched | $1,400 - $2,400 | Custom frame geometry, tempered glass on large panes |
| Custom aluminum window | $950 - $1,900 | Common on mid-century homes in the Valley and Westside |
| Impact-rated window (PGT, CGI) | $1,300 - $2,800 | Required in some LA-area jurisdictions near fire zones |
| Energy-efficient window (ECO Window Systems) | $1,100 - $2,200 | Triple-pane and high-performance low-e options |
| Custom entry door, Therma-Tru fiberglass | $1,800 - $5,200 | Sidelites, transoms, and glass inserts add cost |
| Custom entry door, wood | $2,400 - $6,500 | Staining, custom joinery, and hardware selection |
| Patio door, sliding or French | $2,000 - $5,500 | Width drives price faster than height |
| Custom interior door | $600 - $1,600 | Solid core and custom millwork cost more than hollow |
| Permit and inspection coordination | $150 - $600 | City of LA and surrounding jurisdictions vary |
| Old unit removal and disposal | Included | Part of every Westlight install |
What pushes a quote toward the top of those ranges? Non-standard sizing is the biggest one. The moment a window leaves the standard grid, the manufacturer builds a dedicated frame, which adds material and labor. After that comes glass specification: tempered glass, laminated glass, and impact-rated assemblies all cost more than standard dual-pane. Third is finish and hardware, especially on doors, where a good handle set and a matching stain can add several hundred dollars on their own. Fourth is access. A second-story window over a steep slope in the Hollywood Hills takes longer to install safely than a ground-floor window in a single-story ranch house in Lake Balboa, and that time shows up in the price.
What Affects Custom Window & Door Order Pricing in Los Angeles
Los Angeles isn’t one market. It’s dozens of micro-markets with different housing stock, different permit offices, and different weather exposure. Here’s what actually moves the number on a custom order here.
- Housing age and framing. Much of the housing stock in Koreatown, Highland Park, and Echo Park was built before 1940, which means true-dimension lumber and walls that are often out of square. A custom order handles that better than a stock unit, but the measurement and shimming work takes longer, and that’s reflected in the install labor.
- Glass specification. Low-e glass (a thin coating that reflects heat back into the room in winter and out in summer) is standard on most of our lines. Upgrading to triple-pane or laminated glass adds cost but matters in west-facing rooms that take the full afternoon sun.
- Impact and fire-zone requirements. Parts of the San Fernando Valley and the foothill communities fall under wildfire-adjacent building requirements that call for impact-rated or specific fire-rated assemblies. PGT and CGI both build to those specs, and they cost more than a standard unit.
- Custom sizing and shape. Arched, round, and non-rectangular windows are built to order, and the pricing reflects it. A single arched window can cost double a same-width rectangular one.
- Hardware and finish. Door hardware is where budgets quietly climb. A quality handle set, multipoint locking, and a custom stain or paint match can add $400 to $1,200 to a single entry door.
- Permit jurisdiction. The City of Los Angeles, Santa Monica, Burbank, and Pasadena all run their own permit processes with their own fees and timelines. We handle the paperwork, but the fee itself lands in your quote.
If you want the full picture of how the order process works from first measurement to final walkthrough, our Custom Window & Door Order in Los Angeles page walks through it step by step.
How to Save on Custom Window & Door Order
Custom doesn’t have to mean the most expensive option on the block. A few practical moves bring the number down without cutting into the quality of the finished job.
- Batch the order. Manufacturers price per unit, and a 12-window order costs less per window than three separate orders spread across a year. If you know you’ll replace the back of the house eventually, doing it now with the front saves real money.
- Stay inside standard sizing where you can. If a window opening can be adjusted to a standard size during the install, you get custom performance at closer to stock pricing. We’ll tell you honestly when it’s worth it and when it isn’t.
- Choose the right line for the room. A west-facing bedroom deserves the energy-efficient ECO Window Systems glass. A closet or hallway window doesn’t. We carry eight manufacturer lines so the product matches the job instead of the job bending to fit one brand.
- Skip the upgrade you won’t notice. Triple-pane is worth it in a sun-baked west-facing room and rarely worth it on a shaded north wall. We’ll point out the difference before you commit, not after.
- Get the price in writing first. This is the one that actually saves money. A vague verbal estimate is how budgets blow up. Every Westlight customer gets a written price before any work starts, and that price doesn’t move.

Why Custom Orders Cost More Than Stock (And When It’s Worth It)
Stock windows come in fixed sizes. Custom windows are built to the exact opening in your wall. That difference is the whole reason a custom order carries a higher price tag, and it’s also the reason custom units fit better, seal tighter, and last longer in a house that wasn’t built to a modern grid.
In Los Angeles, that matters more than in most cities. Homes built between 1920 and 1955, which is a large share of the housing in Silver Lake, Los Feliz, and West Adams, rarely have openings that match today’s stock dimensions. Forcing a stock window into an old opening means filling gaps with trim and sealant, and those gaps are where air leaks and water intrusion start. A custom unit fits the opening it was measured for.
When is stock the smarter call? New construction with standard framing, or a rental property where you’re replacing a single damaged unit and matching the existing grid. Outside those cases, custom almost always wins on fit and longevity.
How Long Does a Custom Order Take in Los Angeles?
Plan on 4 to 10 weeks from signed order to installation day. Standard vinyl and aluminum units from our stocked lines usually land on the shorter end, around 4 to 6 weeks. Impact-rated assemblies, wood doors, and anything with custom finish work tend to run 8 to 10 weeks or longer, mostly because the manufacturer builds each unit to your measurements rather than pulling it from a warehouse shelf.
Permit processing adds time in some jurisdictions. The City of LA generally moves faster than smaller neighboring cities with their own review queues, but we build the permit window into your schedule up front so you’re not guessing. Once the units arrive, a typical whole-home install takes one to three days depending on count and access.
FAQs - Custom Window & Door Order Cost
How much does a custom window cost in Los Angeles?
A custom window in Los Angeles runs $850 to $2,800 installed, with most single-window replacements falling around $850 to $1,600. Oversized, arched, and impact-rated units sit at the higher end. Call (903) 354-7134 for an exact quote, free of charge.
Is it cheaper to repair or replace a window in LA?
Repair usually costs $150 to $450 and replacement runs $850 and up, so repair wins on a single cracked pane or a broken sash. But if the seal has failed, the frame is rotted, or the unit is more than 20 years old, replacement is the better spend because you’d be paying twice. We’ll tell you which one makes sense for your window, not ours.
Why is a custom door more expensive than a stock door?
A custom door runs $1,200 to $6,500 installed versus roughly $400 to $1,200 for a stock unit, because it’s built to your exact opening, thickness, and hardware spec. Sidelites, transoms, and custom stain matching add to that. Therma-Tru fiberglass sits in the middle of the range and holds up well in LA’s sun exposure.
Do I need a permit for window and door replacement in Los Angeles?
In most Los Angeles jurisdictions, like-for-like replacement doesn’t require a permit, but changing the size of an opening or altering the structural framing does. Permit fees typically run $150 to $600. We handle the paperwork and confirm requirements for your specific address before work starts. Call (903) 354-7134 and we’ll check your address with you.
Can you give me a written price before the work starts?
Yes, and it’s the first promise in the Kingswell Guarantee. Every homeowner gets a written price before any work begins, plus a committed arrival window and a clean job site. If the work fails within the guarantee period, we come back and fix it at no charge under our 365-Day Done Right Promise.
What happens if my custom order arrives damaged or the wrong size?
We inspect every unit before it goes into the opening. If a manufacturer ships a wrong or damaged piece, we coordinate the replacement and you don’t pay for the delay. That’s part of ordering through a company that carries eight manufacturer lines and stands behind the order, not just the install.
Get a Written Price Before You Commit
Custom window and door orders in Los Angeles don’t have to be a mystery. You should know what you’re paying before the first measurement, not after the last screw.

That’s the Kingswell Way: say the price before the work, show up in the window we gave, leave the place cleaner than we found it, put the guarantee in writing, and come back if it fails.
