Official program pageWindows & Doors in Los Angeles
Light In. Heat Out. Bills Down.
Dual-pane low-E vinyl and fiberglass windows, multi-slide doors and entry doors for Los Angeles homes — Title 24 compliant, rebate-eligible, sound-rated and sealed tight so the AC stops fighting the sun.
What's included
Your Windows & Doors Options
Dual-Pane Low-E Vinyl Windows
The LA default. Two panes with a low-emissivity coating that blocks heat gain in summer and holds warmth in winter — the single biggest comfort jump from single-pane glass. Energy Star rated, rebate-eligible.
Fiberglass Windows
Stronger and more stable than vinyl in direct sun and south-facing walls. Won't warp, rot or fade — the right call for hillside homes and large fixed picture windows.
Aluminum-Clad Wood Windows
Wood warmth inside, weatherproof aluminum outside. The pick when you want a high-end look on a mid-century or Craftsman without repainting every few years.
Multi-Slide & Pocket Doors
Floor-to-ceiling glass that stacks or pockets away for true indoor-outdoor LA living. We handle the structural header, tracks and weather sealing — not just dropping in a box.
Patio, Sliding & French Doors
Replacement sliders, French doors and hinged patio units with energy glass and smooth-rolling hardware. Often the leakiest old opening in the house — and the most visible upgrade.
Entry & Front Doors
Fiberglass and steel entry doors with sidelights and transoms. Insulated, secure and weather-stripped, with the curb-appeal payoff that photographs.
Soundproof & Traffic-Rated Windows
Laminated and triple-pane assemblies rated for STC and OITC — the fix for homes near the 101, 405, LAX flight paths and Metro lines. Cuts outside noise dramatically without changing the look.
Egress & Safety Windows
Code-correct egress windows for basement conversions and bedroom additions, with tempered safety glass where required. We pull the permit and size the opening to code.
Window Walls & Openings
We remove and reframe walls to create large window walls, corner glass and clerestory runs — engineered headers, flashing and Title 24 glazing handled as one scope.
Our promise
What We Lock In Before Day One
Title 24 Compliant By Default
Every window and door we spec meets California's Title 24 glazing requirements for your climate zone. The CF1R and NRa paperwork is in the contract — not a surprise at the counter.
Rebates And Credits Filed
We spec Energy Star and rebate-eligible glass, verify current utility programs the week you sign and help with applicable paperwork.
Full-Frame, Not Insert
We pull the old frame and flash the rough opening — no retrofit insert hiding rot behind a new sash. You see what's in your walls before we close them.
Fixed Price, Written Scope
Window and door model numbers, glass packages, trim scope and warranty terms in writing before a single sash comes out.

How The Build Actually Goes
Six stages, no mystery. We map the timeline to your project and your city's permit requirements before work begins.
- Stage 01
Measure & Spec
We measure every rough opening, note orientation and shading, and spec the glass package (U-factor, SHGC, low-E, sound rating) for your house and your street. 1 visit.
- Stage 02
Proposal & Order
Window and door model numbers, glass packages, trim and rebate math side by side at two or three tiers. You pick, we order and lock the schedule. 3–5 days to confirm; lead times run 2–8 weeks.
- Stage 03
Permit & Title 24
Permit pulled with LADBS or your city, Title 24 glazing compliance documented, HOA drawings if needed. We chase the counter so you don't. 1–3 weeks.
- Stage 04
Prep & Interior Protection
Floors covered, furniture masked, blinds down and old windows and doors out. Full-frame openings inspected and repaired before the new units go in.
- Stage 05
Install, Flash & Finish
New units set, leveled, insulated and flashed. Hardware and weather seals tuned, casing and trim installed, caulked and painted to match. Most homes are 1–3 days on site.
- Stage 06
Inspection & Handoff
City inspection cleared, old windows and doors hauled away, glass cleaned, warranty registered and rebate paperwork filed. Then we're a phone call away.

- Low-E coating blocks UV that fades floors, art and furniture
- Eligible utility-rebate products specified, with paperwork support
- Title 24 compliant glazing and U-factor documented for the permit and your CPA
- Full-frame replacement means new flashing, seal and casing — not a retrofit insert leaking behind the wall

Our living room faced the 101 and was unbearable. They swapped the single-pane for sound-rated triple-pane and the noise dropped overnight — and the AC actually keeps up now.

What It Usually Runs
Real ranges from recent LA jobs so you know where you stand before we ever walk the property. Your exact number comes from a site visit.
City permit fees are not included in project prices or cost estimates. They are separate costs based on what the city charges for your project. WOW processes all permits for every project so clients don't have to worry, and we provide the city fee receipts for their control.
Single window replacement
$750–$1,800 / window
One dual-pane low-E vinyl unit, full-frame, with permit and trim. Price moves with size, glass package and whether it's a retrofit insert or full-frame.
Whole-home window package
$12,000–$45,000
10–20 windows on a typical LA home, full-frame, with Title 24 compliance, permit and haul-away. Before any currently available utility rebates.
Multi-slide or patio door
$3,500–$18,000
Multi-slide, pocket or French patio door with structural header work, flashing and hardware. Large multi-panel systems land at the top of the range.
Entry door with sidelights
$2,500–$9,000
Fiberglass or steel entry door, sidelights and transom, installed and weather-sealed. Curb-appeal upgrade that's often the fastest payoff.
Sound-rated window upgrade
$1,400–$3,200 / window
Laminated or triple-pane STC/OITC-rated assemblies for freeway, flight-path and traffic noise. Priced per opening with the same full-frame scope.
FAQ
Questions People Actually Ask
Usually yes. Window and exterior door replacement triggers a building permit and Title 24 glazing compliance in most LA jurisdictions, especially when you change the opening size, add egress, or swap single-pane for dual-pane on an exterior wall. We pull the permit with LADBS or your city and clear the inspection as part of the contract.
Title 24 is California's energy code. It sets the maximum U-factor and Solar Heat Gain Coefficient your windows must meet based on your climate zone and how much glass the home has. Compliant glass is what unlocks the comfort and rebate upside — and it's required to pass inspection. We document it on the CF1R form and hand it to you.
Federal credits ended Dec 31, 2025, but LADWP and SoCalGas rebates may still apply. We check what's live the week you sign and help with eligible paperwork.
For most Los Angeles homes, dual-pane low-E is the sweet spot — it handles our mild winters and hot summers at a fraction of the cost. Triple-pane earns its keep on sound-rated jobs (freeway, flight path) and on high-elevation or north-facing walls that get cold. We'll show you the payback math, not push the upgrade.
A retrofit insert drops a new window into the existing frame — cheaper and faster, but it hides the old frame and any rot behind it. A full-frame replacement pulls the old frame entirely, lets us inspect and flash the rough opening, and is the right call when the frame is compromised or you want maximum glass area. We default to full-frame and tell you when insert is genuinely fine.
Yes, dramatically. Laminated and triple-pane assemblies rated for STC and OITC can cut perceived outside noise roughly in half — the single biggest improvement for homes near the 101, 405, LAX or Metro lines. The glass package matters more than the frame material; we spec the rating for your street.
No. Modern low-E coatings are nearly clear — they reflect infrared heat without a heavy tint. You get the same light with far less heat gain. If you want a tinted or reflective look we offer that too, but the default is bright and neutral.
On site, most homes are one to three days. The lead time is the glass order — typically two to eight weeks depending on the product line and whether it's standard or custom sizes. We confirm the schedule when you sign and protect every floor and surface during the install.
Yes. For condos and HOA-controlled properties we provide the spec sheets, drawings and color samples your board needs. We won't order glass until the HOA signs off so you're not stuck with custom units you can't install.
Manufacturer coverage typically runs lifetime on vinyl and fiberglass frames and 20 years on insulated glass seals, with registration we handle. Our own workmanship warranty — flashing, sealing, trim and operation — is separate and in writing.
Before. Tighter, low-E glazing lowers your cooling load, which means a smaller solar array covers the same percentage of your bill. Doing it backwards means buying panels to fight the heat leaking through single-pane glass. This is exactly the sequence The Green Room is built around.
Yes. We remove and reframe walls for larger windows, corner glass and clerestory runs — with engineered headers, proper flashing and Title 24 glazing. It's a structural job, not a swap, and we pull the permit and engineer the opening so it's done right.
Either. A slab swap is fast and cheap but rarely solves a draft or a rot problem. A full door-and-frame replacement with new weather seals, threshold and flashing is what actually stops the air leak — we'll tell you which your opening needs.
