Casement Window Replacement in Los Angeles Crank-Out Windows That Seal Tight and Catch the Breeze

Casement window replacement runs $260 to $950 per window, per Angi, based on frame material and glass. A casement swings out on side hinges and presses against a compression seal when it closes, so it seals tighter than a slider. PaneRight LA connects you with local contractors who replace worn casements across Los Angeles and swap sliders for casements where you want more breeze.

Why Is It Time to Replace Your Casement Windows?

Worn hinges, stripped cranks and sagging sashes are the three signs. When the frame is sound, repairing casement windows costs less; when the sash or frame is warped, replacement is the fix that lasts. Have old steel casements? Read about steel casement window restoration before you replace them.

01

Why Won’t Your Casement Window Close All the Way?

The sash has dropped on its hinges, or the frame has bent, so the sash hits the frame before it reaches the seal. Worn hinge arms, a lock that doesn’t line up and swollen wood on old sashes all cause it. Forcing the crank to close it strips the gears.

02

Why Do Casement Cranks Keep Failing After Every Repair?

The crank isn’t the real problem. If the sash drags on the sill or the hinges bind, every turn puts extra force on the gears, and a new operator wears out just like the old one. Fix the hinges and sash first, then put in the new crank.

03

Are Sagging Casements Letting In Drafts and Rain?

Yes. A sagging sash leaves a gap at the top corner on the lock side, and wind drives dust and rain through it. Crushed or torn weatherstripping makes it worse. New hinges and seals fix a sound sash; a warped or rotted one needs casement window sash replacement or a new window.

What’s Included in Our Casement Window Replacement Service?

Every job covers measuring, windows built to size, removal, a sealed install, new screens, the permit and haul-away. Most stucco homes get retrofit casements that cover the old frame, and full-frame installs are used where frames are rotted or bent.

01

Can You Switch Sliders or Double-Hung Windows to Casements?

Yes. A casement fits the same opening, and a wide opening can take two casements side by side, or a casement next to a fixed pane. Check egress first, since a casement’s clear opening differs from a slider’s. See our sliding window replacement page for keeping sliders.

02

Do New Casements Come With Inside Screens and Fold-Away Cranks?

Yes. Casement screens mount on the inside, since the sash swings out. Most new casements have a fold-down or nesting handle that tucks away so it doesn’t catch blinds. For casement window screen replacement on windows you keep, see our window screen replacement service.

03

Can You Pair Casements With a Large Picture Window?

Yes. A fixed picture window with a casement on one or both sides gives you a big view plus airflow. It’s a common setup for living rooms facing a yard or the hills.

How Much Does Casement Window Replacement Cost in Los Angeles?

Angi puts casement replacement at $260 to $950 per window. Size, frame material, glass and grids set the price.

JobCost (Angi)
New casement window$260 to $950
Casement window glass replacement$150 to $1,200
Crank or lock repair$50 to $200

Why Do Casements Cost More Than Sliders?

A casement has hinges, a crank operator and a multi-point lock, and a slider has a latch and rollers. The sash also has to be stiff enough to hang from one side without sagging. That added hardware and framing raises the price.

How Can You Save on a Casement Window Project?

Use casements where you need airflow or egress, and fixed or slider windows elsewhere. Pick standard sizes and white or tan frames. Replace several windows in one visit so setup and permit costs are shared.

Casement or Awning: Which Works Better in Kitchens and Bathrooms?

Over a kitchen sink, a casement is easier to crank open than pushing up a slider across the counter. An awning window hinges at the top and swings out from the bottom, so you can leave it open in light rain. Use awning windows high on bathroom walls for privacy and airflow, and casements where you need a full opening.

How Are Casement Windows Installed, Step by Step?

  1. Measure. Every opening, plus egress checks in bedrooms.
  2. Quote. A written price for each window.
  3. Permit and order. Contractors file the permit and order windows built to size.
  4. Remove. Old sashes, hardware and the frame if needed come out.
  5. Install and seal. Windows go in plumb and square, so the sash hangs true.
  6. Test. Contractors crank, lock and check the seal on every window.

What Should LA Homeowners Know Before Choosing Casement Windows?

01

How Wide Must a Casement Be to Meet Bedroom Egress Rules?

The California Residential Code calls for a clear opening of at least 5.7 square feet, 20 inches wide and 24 inches tall, with a sill no higher than 44 inches. A 20-inch clear width needs about 41 inches of clear height to reach 5.7 square feet. Egress hinges swing the sash wide open for the most clear space; see our egress window installation page.

02

Do Casement Windows Hold Up in Santa Ana Winds?

A closed casement does well, since wind from outside presses the sash harder into its seal. An open sash can catch a gust and bend the operator or hinges. In January 2025, the National Weather Service warned of Santa Ana gusts up to 100 mph, so close casements when a wind advisory goes out in Porter Ranch, Altadena or the Palisades.

03

Will an Outswing Casement Block Your Walkway or Patio?

It can. A casement on a narrow side yard or next to a patio table sticks out as far as the sash is wide. Use a slider or awning window there, or pick a narrower casement.

Why Do LA Homeowners Choose PaneRight LA for Casement Windows?

  1. Repair first. Contractors fix hinges and cranks when the window is sound.
  2. Egress checked. Every bedroom casement measured against code.
  3. Plumb installs. Frames set square so sashes don’t sag.
  4. Itemized quotes. Brand, series, U-factor and SHGC for every window.
  5. Warranty in writing. Ask for a written labor warranty on top of the manufacturer’s warranty.

Where Do Contractors Install Casement Windows in Los Angeles?

Contractors work across the San Fernando Valley, Burbank, Glendale, Pasadena, Altadena, Santa Monica, Beverly Hills, Pacific Palisades, the South Bay and Long Beach. That covers Spanish homes in Los Feliz with old steel casements, mid-century homes in the Valley and beach homes in Venice that catch the afternoon ocean breeze.

Casement Window FAQs

What Are the Cons of Casement Windows?

They cost more than sliders, the crank can wear out and the sash swings into outdoor space. Screens go inside, and you can’t fit a window AC unit in one.

Are Casement Windows More Secure Than Sliders?

Yes. Casement locks hook into the frame, and multi-point locks grab it in more than one spot. A slider can be lifted out of its track without an anti-lift device, which LADBS requires on sliding windows for that reason.

How Do You Clean the Outside of a Casement Window?

Crank it fully open. Many new casements have cleaning hinges that leave a gap on the hinge side, so you can reach the outside glass from indoors.

How Big Can a Casement Window Be?

Angi lists standalone casements up to 36 inches wide and 36 to 72 inches tall. For wider openings, pair two casements or add a fixed pane.

Can You Repair a Casement Crank Instead of Replacing the Window?

Yes. Casement window crank replacement swaps the operator for a matching model, and Angi puts crank and lock repairs at $50 to $200 per window. See our window repair service. For 1920s steel casements, see our steel casement window restoration page.
