5 Best Window Companies in Los Angeles (2026)

Independently ranked by our review of ratings, reviews and reputation · How we chose

By Brad Smith, Home Services Expert · ✓ Data verified August 2026 · 8 min read

Picking among window companies in Los Angeles is one of those projects where the name on the truck matters as much as the glass itself. One company here alone has logged nearly 1,300 Google reviews, more than four times the combined total of the rest, so scale and reputation vary sharply depending on whether you want a national brand's process or a smaller shop's hands-on pricing.

Short answer: Renewal by Andersen of Greater Los Angeles leads on volume with 4.7 stars across 1,297 reviews and a full showroom process. Lion Windows & Doors posts the highest rating among smaller shops at 4.8 across 59 reviews, and 3B Windows & Doors (4.5, 148 reviews) is a family-owned vinyl window specialist known for direct, competitive pricing.

It has by far the deepest review base of any window company on this page, covering both window and sliding glass door replacement.

What people praise

Multiple installers and supervisors on-site with daily check-ins, per reviewers
Reviewer-confirmed sliding glass door and folding door installations
Large-scale operation with a physical showroom for browsing options
Consistent five-star reviews across a large volume

Worth knowing

One reviewer described the finished window frame as bulkier than the showroom sample and felt the local office was hard to reach afterward about it
Pricing runs at the premium end typical of a national brand

Our take: The clear volume leader with a formal installation process and brand-backed warranties. A safe choice for a full-home replacement, though ask specifically about final frame dimensions before signing given the one detailed complaint on file.

Cortes Auto Glass

4.5371 Google reviews

Cortes Auto Glass is primarily an automotive glass repair shop, replacing windshields and vehicle side windows rather than residential household windows. Google's category data lists it under window installation alongside auto parts and auto repair, and every review we found describes car glass work, not home window installation. We're including it because it surfaced in the data for this category, but it does not appear to be a residential window company.

What people praise

Reviewer-confirmed fast turnaround on windshield and vehicle side window replacement
Competitive pricing reported by multiple reviewers
Tint matching mentioned as a specific, appreciated detail on vehicle glass jobs

Worth knowing

Not a household window installer, based on every review we could find
One reviewer reported a faulty seal on a windshield install that led to water intrusion and disputed follow-up
Another described poor customer service and low-quality glass

Fast Windows & More Inc

4.3151 Google reviews

Fast Windows & More Inc is a family-owned Los Angeles window supplier offering vinyl and aluminum windows, patio doors, closet doors, and shower doors, with the company citing 15-plus years in business. Reviewers describe quick turnaround, sometimes same-day for custom glass orders, and competitive pricing versus big-box home stores. It's the lowest-rated name here, driven partly by complaints about front-desk customer service.

What people praise

Reviewer-confirmed fast turnaround, including same-day custom glass work
Wide product range, from vinyl and aluminum windows to patio and closet doors
Prices reviewers describe as better than big warehouse stores
Long-standing local operation

Worth knowing

Multiple reviewers specifically flagged unfriendly or unhelpful front-desk service
Lowest rating on this page, though still comfortably positive overall

How we score these window companies

Every number on this page comes from public Google data as of the date shown, not opinion or payment. Rating is the business’s live Google star average. Review volume measures how many customers have rated them, benchmarked against other Los Angeles window companies. Confidence weighs the rating by that volume, so a strong score from over a thousand reviewers carries more weight than the same score from a few dozen. Recency reflects how recently customers are still leaving reviews. No business can pay to change these numbers.

What drives window replacement costs in Los Angeles (2026)

We don’t have a locally sourced, citable price table for window replacement in LA yet, so we’re not publishing numbers we can’t back up. Cost generally depends on window count, frame material (vinyl versus aluminum versus wood-clad), whether it’s a like-for-like swap or a full frame replacement, and glass upgrades like low-E coating. Get itemized quotes from at least two companies and confirm whether they include disposal of the old windows.

Window companies serving Los Angeles

The companies above serve greater Los Angeles, including Torrance, West LA, Downtown, South LA, and surrounding neighborhoods. Searching for window replacement near me? Every listing below shows a live phone number and directions so you can reach the closest option fast.

What to ask before hiring a window company

Is this a like-for-like replacement or a full frame change, and how will that affect the final opening size?
What frame material and glass options do you offer, and what’s the energy-efficiency rating?
What’s the warranty on the windows versus on the installation labor?
Does the quote include removal and disposal of the old windows?
How long will the installation take, and how many crew members will be on-site?
Can I see a sample of the finished frame, not just a catalog photo?

Frequently asked questions

How did you choose these Los Angeles window companies?

We started from window companies in Los Angeles with a public Google presence, then ranked by rating, review volume, consistency, and recency. See How we score these window companies above.

Are these rankings paid?

No. Rankings come from the public Google data in the scorecard. A business can pay to be a Featured Partner, which adds a badge and top placement, but that never changes another business’s score or position on the underlying data.

How often is this updated?

The data carries a verified date (August 2026 on this page). We refresh listings periodically so ratings and review counts stay current.

What’s the difference between vinyl and other window frame materials?

Vinyl tends to cost less and needs little maintenance, while wood-clad and aluminum options can offer different aesthetics or durability tradeoffs. Ask each company which materials they specialize in installing.

Should I get multiple window quotes before choosing a company?

Yes. Window costs vary widely by material, glass package, and installation approach, so a second or third quote helps you compare scope, not just price.

The bottom line

Renewal by Andersen is the safe default for most Los Angeles homeowners given its scale and formal process, while Lion Windows & Doors stands out for honest, no-pressure guidance on smaller jobs. Skip Cortes Auto Glass for household window work; it’s a car glass shop, not a residential window installer. Whoever you choose, confirm the final frame dimensions before signing.
