Casement Windows

Casement windows are hinged on the side and crank outward, which makes them one of the tightest-sealing designs you can put in a Los Angeles home. They’re the window we recommend when a room faces a windy canyon or a busy street, because the sash presses against the weatherstripping when closed, blocking drafts better than most sliding designs. Westlight Windows Los Angeles installs casement units from PGT, CGI, and ES Windows, with most single casement replacements running $600 – $1,400 installed depending on size and glass package. The crank mechanism is the part that fails most often, so we check gearing and hardware operation on every install before we call it done.

Side-hinged operation for maximum seal

Because a casement window closes against a fixed frame, it naturally compresses its own gasket. In older Los Angeles houses, that means a noticeable drop in street noise the day the window goes in.

Where we see the biggest benefit

Bathrooms over a vent pipe, kitchens facing an alley, bedrooms near a freeway wall-these are the spots where Awning & Hopper Windows also work well in Los Angeles. These are the spots where casement windows earn their keep in Los Angeles.

Double Hung Windows

Double hung windows have two sashes that slide vertically, so you can open the top, the bottom, or both at once. In Los Angeles, that matters in two-story homes where cleaning an upper window from inside becomes an easy job instead of a ladder project. Most double hung replacements from Westlight Windows Los Angeles run $500 – $1,300 per unit installed, with the final number shifting on glass coating, frame material, and whether the existing opening needs reframing. We install double hungs from ECO Window Systems and PGT, and every unit is shimmed, leveled, and insulated at the rough opening before trim goes back on.

Top sash ventilation and easy cleaning

Tilting the top sash down lets warm air out while cooler air comes in low. And when both sashes tilt inward, you clean the outside of the glass from inside your own living room.

Replacing old wood sashes in pre-war Los Angeles homes

We see a lot of double hung retrofits in neighborhoods with 1920s and 1930s houses. The old wood sashes warp, paint seals the frame shut, and the result is a window that hasn’t opened in a decade.

Vinyl Windows

Vinyl windows are built with extruded PVC frames, which means they never need painting and never rot, warp, or rust. For a Los Angeles homeowner dealing with salty air at the coast or sprinkler strikes in inland neighborhoods, vinyl removes a whole category of maintenance. Westlight Windows Los Angeles installs vinyl windows from ECO Window Systems and CWS, and most vinyl replacements run $400 – $950 per unit installed. That makes vinyl the most predictable budget option we offer, with the trade-off being fewer color and finish choices compared to aluminum or composite.

Why vinyl wins in coastal Los Angeles air

Salt air chews through wood and pits aluminum over time. Vinyl doesn’t flinch. That’s why we recommend it without hesitation for homes west of the 405.

Putting a number on the decision

If you’re comparing vinyl to wood or fiberglass, the price spread is often $300 to $600 per opening. We’ll show you the written breakdown before any work starts, so the decision is yours without pressure.

Picture Window

A picture window is a fixed pane of glass that doesn’t open, built to frame a view. In Los Angeles, that means a west-facing wall taking in the late-afternoon sun over the hills, or a south-facing living room pointing at a backyard that deserves the full treatment. Picture windows are the least expensive opening to replace because there’s no operating hardware, with most units running $350 – $900 installed at Westlight Windows Los Angeles. We can size picture windows with low-e coatings and gas fills from ECO Window Systems or PGT, so the view doesn’t come with a wall of heat in August.

Glass packages that cut heat without dimming the room

Low-e glass is a thin coating that reflects heat back into the room in winter and out in summer. For a picture window, it means you keep the view and lose the glare.

Framing for big openings

A five-foot picture window needs a heavy-duty frame and proper header support. Our installers size the header before cutting the rough opening, so the wall stays structural while the view goes in.

Bay Window Installation

Bay window installation adds a projecting window structure that extends outward from your exterior wall, giving you floor space, a deep sill, and a wider light path than a flat window. It’s one of the more involved window projects we take on in Los Angeles, because the bay is built from three or more window units joined at angles and supported from below. Expect most bay window installations from Westlight Windows Los Angeles to run $1,800 – $4,500 installed, depending on the width, the roofing over the bay, and the window units selected. Owen Satterfield’s crews have installed bay windows in bungalows, Tudor revivals, and mid-century builds across the city.

Structural support top to bottom

The cantilevered section needs a solid knee brace or cable support, plus flashing at the roof seam. We pull any required permits and have the work inspected before we close the wall.

Ventilation in a bay fixed front

Most bay designs use a fixed center picture unit with operating casement or double hung windows on the angled sides. That gives you the view plus airflow when the wind shifts in the evening.

Window Contractor

A window contractor is the person or company responsible for installing windows to the manufacturer’s specification, in a way that keeps the building envelope sealed and the window operating correctly for years. In Los Angeles, hiring a licensed window contractor matters because this city’s building department has specific requirements for egress, thermal performance under Title 24, and structural attachment. Westlight Windows Los Angeles has operated as an independently owned Kingswell location since 2009, handling both retrofit and full-frame window replacement. Most contractor-installed window work runs $500 – $1,600 per opening depending on the scope.

Retrofit versus full-frame replacement

When the existing frame is square and sound, a retrofit inserts a new window inside the old frame with less demolition. When water damage or rot has set in, a full-frame replacement removes everything to the studs. We’ll show you both options and the written price for each.

What a good window contractor checks before quoting

Squareness of the rough opening, condition of the header, depth of the jamb, and whether the existing flashing was ever done correctly. Missing any of these turns a straightforward install into a leak inside six months.

Window Installers

Window installers are the technicians who show up at your Los Angeles home and do the physical work: removal, shimming, leveling, insulating, sealing, and trim. The difference between an okay install and a problem house is how these details get handled. Every window installer at Westlight Windows Los Angeles is background-checked and uniformed, so you know exactly who is walking through your door. Our crews handle window installation and window replacement work across Los Angeles, from East Los Angeles to the coast.

Shimming and leveling before fastening

A window dropped into a slightly out-of-square opening will bind, leak, and wear out its hardware early. We level and shim every unit before the first screw goes in, then insulate the gap.

Interior trim and exterior capping

After the window is in, the opening gets insulated and trimmed. Exterior capping bends aluminum over the old wood frame so you never paint that trim again.

Brands We Service

Westlight Windows Los Angeles installs products from eight manufacturer lines, so we’re never trying to force one brand onto your home. PGT and CGI are our go-to impact-rated lines for coastal and canyon wind zones. ViewLux gives us an aluminum option with clean sightlines for mid-century and contemporary Los Angeles houses. CWS rounds out the vinyl and aluminum options when budget is the primary driver.

Because we install these brands every week, our crews know the hardware, the flashing details, and the installation tolerances specific to each. That matters when a warranty issue comes up down the line, because we can diagnose and correct without guessing. Whether you have PGT, CGI, ViewLux, or any other make in your home, we can help.

Signs You Need a Pro Right Now

• Condensation between the panes. That’s a failed seal, which means the insulating gas has escaped and the glass unit can’t do its job anymore. In Los Angeles, it shows up first on south and west-facing windows that get the most sun.
• Drafts you can feel with a hand. If air moves around the frame on a windy afternoon, the weatherstripping or the sealant has failed. You’re paying to heat or cool the street.
• Sashes that stick or drop. A window that won’t stay open is a safety issue, and a window that won’t close is a security issue. Both point to worn hardware or a failing balance system.
• Visible rot or water staining around the frame. Water has already found a path. The longer it sits, the more framing gets replaced, and the bigger the final bill becomes.
• Single-pane glass that radiates heat. If the glass itself is hot to the touch in the afternoon or cold in the morning, you’re losing energy constantly. Title 24 requirements in Los Angeles make replacement mandatory when doing significant renovation anyway.
