Window Replacement Contractor Services in Los Angeles

Full Frame Window Replacement

We tear out the old frame, sill, and trim down to the studs, then set a new unit with fresh flashing and insulation. Best for rotted frames or homes changing window size. Common on older Sherman Oaks and Pasadena houses where the original wood has given up.

View Details

Retrofit Window Replacement

Retrofit keeps your existing frame and fits a new window into the opening, which means less stucco repair and a faster install day. Ideal when the frame is solid but the sashes and glass are done. Most retrofit jobs finish in one day per room.

View Details

Insert Window Replacement

Insert windows drop into the existing frame pocket with minimal disruption to interior trim and exterior finishes. A clean, affordable choice for condos and rentals where you want better glass without a full tear-out. We measure the pocket depth to the sixteenth of an inch.

Window Sash Replacement

When only the moving part is failing, sash replacement saves you the cost of a whole unit. We match the sash profile, replace the weatherstripping, and rebalance the hardware. A good fit for double hungs with cracked glass but a healthy frame.

Double Hung Window Replacement

Double hung units tilt in for cleaning and vent from top or bottom, which matters on two-story homes in Studio City and Encino. We set new balances and check the tilt latches before we leave. Available in vinyl, fiberglass, and wood.

View Details

Single Hung Window Replacement

Single hung windows cost less than double hung and work well in bedrooms, hallways, and rentals where only the bottom sash needs to open. We install them with new flashing tape and silicone caulk so water stays outside where it belongs.

Casement Window Replacement

Casement windows crank open for full ventilation and seal tight against wind-driven rain. Popular in kitchens and coastal-facing rooms from Santa Monica to Woodland Hills. We check the crank mechanism and hinge alignment on every unit before sign-off.

View Details

Sliding Window Replacement

Sliding windows give you wide glass and an easy horizontal glide, ideal for patios and family rooms. We replace worn rollers and tracks so the new panel moves with one finger. Available in two-, three-, and four-panel configurations.

View Details

Bay Window Replacement

Bay windows push out for extra floor space and light, and they are a common upgrade on Valley ranch homes. We build the seat, roof, and side panels to match your exterior, then seal every joint. Expect a two-day install for most bays.

View Details

Bow Window Replacement

Bow windows use four or more panels in a gentle curve, giving a softer look than a bay. We frame, flash, and finish the curved head and sill so nothing leaks behind the stucco. A strong choice for living rooms in Northridge and Tarzana.

View Details

Picture Window Replacement

Picture windows are fixed glass, so they deliver the biggest view and the best energy numbers per square foot. We use low-E glass and argon gas to cut heat gain on west-facing walls. Perfect above a sofa or behind a dining table.

View Details

Awning Window Replacement

Awning windows hinge at the top and open outward, so you can vent a room even in light rain. They pair well above kitchen sinks and in bathrooms. We set the friction stays so the sash holds wherever you leave it.

View Details

Garden Window Replacement

Garden windows box out from the wall with glass on three sides and a shelf for plants. Great for kitchens that need light but no direct sun. We insulate the base and seal the exterior corners against our occasional heavy winter rain.

View Details

Egress Window Replacement

Egress windows meet code for bedrooms and basements, with a clear opening big enough to climb through. We size the unit to the required clear width and height, then verify the well or clearance. Required on many permitted remodels in Los Angeles County.

View Details

Storm Window Replacement

Storm windows add a second layer of glass or polycarbonate over your existing unit, cutting noise and drafts for less than a full replacement. A practical fix for historic homes in Pasadena and Beverly Hills where the original windows must stay.

View Details

Vinyl Window Replacement

Vinyl is the workhorse material here: low maintenance, never needs paint, and handles Southern California sun without warping. We use multi-chamber profiles with welded corners. The most affordable path to ENERGY STAR rated performance for most homes.

View Details

Fiberglass Window Replacement

Fiberglass frames expand and contract less than vinyl, so they hold their seal through big temperature swings from the Valley to the coast. Strong, paintable, and a good match for stucco exteriors. We stock Marvin and Milgard fiberglass lines.

View Details

Wood Window Replacement

Wood windows match the character of Craftsman and Spanish homes across Los Angeles, and they can be stained or painted to your trim. We specify rot-resistant species and prime every edge before install. Andersen, Pella, and Kolbe options available.

View Details

Aluminum Window Replacement

Aluminum frames are slim, strong, and rust-free, which suits modern and mid-century homes. We use thermally broken profiles to reduce heat transfer. A clean look for large openings where you want maximum glass and minimum frame.

View Details

Composite Window Replacement

Composite frames blend wood's look with engineered durability, resisting rot and moisture better than natural wood. A smart pick for bathrooms, kitchens, and any window that sees splash or humidity. We finish them to match your existing trim.

How Our Window Replacement Process Works

Replacing windows should not feel like a mystery. Here is the same four-step path we run on every job, from a single bedroom sash in Van Nuys to a full house in West Hills.

Free Measure and Quote

We come out, measure every opening with a tape measure and level, and note the frame condition. You get an itemized quote by email, usually within 24 hours. No deposit to get the number.

Order and Schedule

Once you approve, we order your units from Andersen, Pella, Marvin, Milgard, or Simonton. Standard sizes arrive in two to three weeks. We confirm your install date and give you a window, not a vague morning.

Install Day

Our crew lays drop cloths, pulls the old units, checks for rot, and sets the new windows with shims, flashing tape, and insulation. We caulk inside and out, then test every sash for smooth operation.

Walkthrough and Warranty

Before we leave, you inspect each window with the lead installer. We hand over the manufacturer paperwork and our five-year workmanship warranty. If a latch sticks or a seal fails, you call us, not a call center.

Anyone can hand you a catalog and a quote. We measure, order, install, and warranty the whole job, so there is one number to call if anything is off. Here is what that looks like in practice.

Licensed, Insured, and Code-Correct We hold an active California Contractor License through the CSLB and carry full liability and workers comp coverage. Every install meets current California building code, and we pull permits when your project needs them. You get documentation, not a handshake.
Same-Day Estimates, Seven Days a Week Call before noon and we can usually measure the same day. Our estimators arrive in marked trucks with samples of vinyl, fiberglass, and wood so you can compare in your own light. Quotes are itemized by window, not a lump sum you have to decode.
Energy Ratings That Actually Cut Bills We spec NFRC-rated units with low-E glass and argon gas, which cut heat gain on west-facing walls and hold warmth on cold Valley nights. Many of our windows qualify for ENERGY STAR, and we will show you the label before you buy.
