Every wood window replacement we do includes the unit, the labor, the flashing, the caulk, the trim work and the cleanup. We quote the whole job up front so there's no surprise line item when the truck shows up.
Every opening is measured to the sixteenth of an inch, and we check the rough opening for rot, out-of-square framing and prior water damage before we order anything. If the framing needs work, you'll know before we place the order, not after.
Your choice of Andersen, Pella, Marvin, Kolbe, Loewen, Milgard, Simonton or Jeld-Wen. We spec low-E glass and argon fill on every unit unless you tell us otherwise. Grid patterns, finishes and hardware are all confirmed in writing before the order goes in.
New flashing tape on the rough opening, silicone caulk on the exterior and interior, and insulation gun foam in the gap around the frame. This is the step that keeps water out for the next 30 years, and we don't skip it.
Interior casing and exterior trim are installed and caulked. We match the existing profile where we can and fabricate custom trim where we can't. Paint touch-up is on us if the new trim needs a spot coat.
Full-frame jobs get a permit through the Los Angeles Department of Building and Safety. We pull it, schedule the inspection, and handle any corrections the inspector flags. You don't fill out a single form.
Old windows, glass, packaging and debris all leave with us. We sweep the floor, wipe down the sills, and walk the job with you before we pull out of the driveway. You shouldn't have to clean up after a contractor.
Wood Window Replacement Los Angeles CA is the removal of your existing wood-sash windows and the installation of new wood-framed units, including the frame, sash, glass, weatherstripping and flashing. On a full-frame job we pull the old unit down to the rough opening, check for rot in the header and sill, shim the new frame level, and seal it with silicone caulk and flashing tape. On an insert job we keep the existing frame and drop a new sash-and-jamb assembly inside it, which saves on trim work and drywall repair.
Los Angeles homes take a specific beating: UV that bakes south-facing wood until it checks and cracks, marine layer moisture in Santa Monica and Venice that swells frames, and 40-degree day-night swings in the Valley that work seals loose. If you're searching for wood window replacement near me Los Angeles, the telltale signs are foggy glass, sticking sashes, and water staining on the interior sill. We've been replacing wood windows in Los Angeles County since 2010, and we know which neighborhoods have original 1920s Douglas fir and which have 1980s aluminum-clad units that are ready to go.
Five steps, no surprises. We measure, order, install, seal and walk the job with you before we pack up the truck.
Schedule
Call or book online — a real human picks up and confirms a 2-hour arrival window.
Diagnose
Licensed tech inspects on-site, then walks you through the cause and your options.
Fix
The job is completed to code and done right the first time — no shortcuts, no surprises.
Guarantee
Every job backed by a written workmanship warranty — and we stand behind it.
Tape measure and laser level
Every opening is measured to the sixteenth of an inch and checked for square and plumb before we order. A window that's out of level by an eighth of an inch will stick within a year.
Pry bar and utility knife
Used to remove the old sash and trim without damaging the surrounding drywall or stucco. We cut the caulk line first so the trim comes off clean and can be reused if you want it.
Caulking gun and silicone caulk
Exterior and interior sealing on every unit. We use 100 percent silicone on the exterior and paintable latex on the interior so the trim can be painted without adhesion problems.
Insulation gun
Low-expansion foam goes in the gap between the new frame and the rough opening. It stops air infiltration and adds an R-value to the assembly without bowing the frame.
Window setting blocks and shims
The frame sits on setting blocks at the sill and is shimmed at the jambs and head. This is what keeps the sash operating smoothly for the life of the window.
Flashing tape
Applied to the rough opening sill and jambs before the new unit goes in. This is the single most important step for water management, and it's the one most installers skip.
Drill and screwdriver set
Used to drive screws through the nailing fin and into the framing. We use stainless fasteners on exterior work so they don't rust out in the marine layer.
AAMA installation standard
We follow the American Architectural Manufacturers Association installation standard on every job. That means proper flashing sequence, correct fastener spacing and a verified seal at the rough opening. It's the difference between a window that passes inspection and one that leaks.
NFRC-labeled glass packages
Every insulated glass unit we install carries an NFRC label listing U-factor, SHGC and visible transmittance. You can look up the exact performance of your window before it goes in. No mystery glass.
ENERGY STAR certification
Our standard glass package meets ENERGY STAR requirements for the Los Angeles climate zone. That means low-E coating, argon fill and a thermally broken frame. It's the baseline, not an upgrade.
Permit-pulled full-frame work
Every full-frame job gets a permit and a final inspection through the Los Angeles Department of Building and Safety. We handle the paperwork and the corrections. It protects your resale value and your insurance coverage.
01
What we do: We measure the existing profiles, spec new wood units with true divided lites and a factory-primed exterior, and pull the permit through the Los Angeles Department of Building and Safety. Historic profile match is confirmed before we order.
→ You keep the original look, gain low-E glass and modern weatherstripping, and pass historic review without a fight.
02
What we do: We do a fast measure, quote insert wood windows with new sills and flashing, and schedule the install inside the escrow window. Most 10 to 15 window jobs finish in two to three days.
→ The inspection items clear, the house shows better, and you close escrow without a price reduction.
03
What we do: We replace with Marvin or Andersen wood units, dual-pane laminated glass, and fresh flashing and caulk. We also tune the balances and replace the weatherstripping on every sash.
→ Street noise drops by 25 to 35 decibels, the drafts stop, and the rooms stay warmer in winter without touching the thermostat.
04
What we do: We offer wood window replacement 24/7 Los Angeles emergency service. A tech comes out, boards the opening, and we order the replacement unit the next morning. Permanent install usually happens within 7 to 10 days.
→ Your house is secure the same night, and the permanent window is in before the next rain.
Los Angeles is not one climate. A wood window in Santa Monica fights marine layer moisture and salt air. The same window in Woodland Hills bakes at 105 degrees in August and drops to 55 at night. We spec different glass, different finishes and different flashing details depending on which side of the hill you're on. In historic districts like Angelino Heights and Hancock Park, we work within the Historic Preservation Overlay Zone rules and match original profiles. In the Valley, we see a lot of 1950s and 1960s ranch homes with original Douglas fir frames that are ready for replacement. Wherever you are in Los Angeles County, we pull the permit, follow AAMA installation standards, and use ENERGY STAR-rated glass. If you're comparing wood window installation cost Los Angeles quotes, ask each contractor what glass package and flashing method they're using. The cheap quote usually skips both.
Sherman Oaks
Mix of 1950s ranch homes and newer builds. Many original wood windows are still in place and ready for replacement. We do a lot of insert work here to preserve original interior trim.
Santa Monica
Marine layer moisture rots sills faster here than anywhere else in the county. We spec aluminum-clad exteriors and heavier flashing on every Santa Monica job.
Pasadena
Historic districts and Craftsman bungalows. True divided lites and profile-matched trim are standard on our Pasadena work. We've been through the Cultural Heritage Commission process many times.
Woodland Hills
Inland heat and wide day-night temperature swings. We spec low-E glass with a low SHGC to cut heat gain on west-facing walls. Fiberglass or aluminum-clad exteriors hold up better here than bare wood.
North Hollywood
Older housing stock with a lot of 1920s and 1940s wood windows. Many have been painted over so many times the sashes are frozen. We replace the sash and jamb liner together to fix it right.
UV exposure that bakes south and west-facing wood
Bare or poorly finished wood checks, cracks and peels within 5 to 7 years. We spec factory-primed or aluminum-clad exteriors and low-E glass to cut the UV load on the interior.
Marine layer moisture in coastal neighborhoods
Wood swells and sills rot faster within 3 miles of the ocean. We use stainless fasteners, heavier flashing and aluminum-clad exteriors on coastal jobs.
Wide day-night temperature swings in the Valley
Frames expand and contract daily, which works caulk joints loose and causes sashes to stick. We shim and seal with materials rated for the swing and tune the balances on every sash.
Historic Preservation Overlay Zone requirements
Vinyl and many modern profiles are not allowed in HPOZ neighborhoods. We match original wood profiles and handle the review paperwork so the job passes without a delay.
Wood windows fail in predictable ways here. UV, marine moisture and temperature swings all take their toll. Here are the four problems we see most often and what we do about them.
Problem
Rot spreads into the rough opening and header, and eventually the window stops sealing entirely. Water gets behind the stucco and into the wall cavity, which turns a $1,400 window job into a $6,000 framing repair.
Our Fix
We pull the unit, cut out the rotted wood, sister in new framing material, treat the surrounding wood with a borate preservative, and install new flashing tape before the new window goes in. The repair is permanent, not a patch.
Problem
Once the seal fails, moisture gets between the panes and the window is permanently cloudy. You lose the insulating value of the argon fill and the low-E coating stops working. Your energy bill climbs and you can't see out.
Our Fix
We replace the insulated glass unit with a new NFRC-labeled IGU from the same manufacturer. If the sash is also failing, we replace the whole sash. Either way, the fog is gone and the U-value is back to spec.
Problem
Wood swells in the marine layer and shrinks in the Valley heat. A stuck sash is a fire-safety issue in a bedroom and a ventilation problem everywhere else. Forcing it cracks the sash and breaks the balance system.
Our Fix
We replace the sash and jamb liner, install new spiral or block-and-tackle balances, and tune the fit so the window opens with two fingers. If the frame is out of square, we address that too instead of just replacing the sash.
Problem
A drafty wood window leaks conditioned air year-round and lets in 30 to 40 decibels of street noise. On a busy street in Studio City or under the flight path in Pacoima, that's the difference between sleeping and not sleeping.
Our Fix
We install new wood units with dual-pane laminated glass, fresh weatherstripping and a properly shimmed frame. A tight install with the right glass cuts noise by 25 to 35 decibels and stops the draft at the source.
Wood frames outperform vinyl on looks, repairability and resale in Los Angeles's historic districts. Here's what you actually get when you replace wood with wood instead of swapping to plastic.
Original Character Preserved
If your home is in a Historic Preservation Overlay Zone, vinyl is often a non-starter. Wood sashes match the original profile, muntin pattern and depth, so your 1912 Craftsman still looks like a 1912 Craftsman. We match existing trim profiles and can replicate divided-light grids down to the inch.
Real Energy Savings
A single-pane 1960s wood window runs about U-0.90. A new wood unit with low-E glass and argon gas hits U-0.28 to U-0.32, which cuts heat gain on west-facing walls by 40 to 60 percent. That's a measurable drop on your summer DWP bill, not a marketing number.
Repairable, Not Disposable
Vinyl cracks and can't be patched. Wood can be sanded, epoxied and repainted for decades. A wood window installation Los Angeles homeowners invest in today can be serviced in 2046 with a scraper and a can of paint instead of a full tear-out.
Quieter Rooms
Wood is denser than hollow vinyl, and a properly shimmed and caulked wood frame with laminated or dual-pane glass cuts street noise by 25 to 35 decibels. That matters on a busy street in Studio City or under a flight path in Pacoima.

“We had 14 original 1952 wood windows that were painted shut and foggy. American Reliable measured on a Tuesday, quoted Wednesday, and installed in three days two weeks later. They matched the original trim profile exactly. Our DWP bill dropped $94 the first full month. Crew cleaned up better than they found it.”

“Marine layer had rotted the sills on our north-facing windows. They pulled the units, replaced the rotted framing, flashed everything properly, and installed new Marvin wood windows with low-E glass. Passed Santa Monica inspection first try. Two years in, zero leaks, zero sticking.”
David K.
Homeowner, Santa Monica
“We're in a historic district and vinyl was off the table. They walked us through the Cultural Heritage Commission requirements, spec'd true divided lites, and handled the paperwork. The new windows look original. Neighbors have asked for their number three times already.”

Real answers to the questions we hear most often from local homeowners and property managers.
When the existing frame is rotted or out of square, full frame replacement pulls everything down to the rough opening. We install new flashing, new sill pan and new trim. This is the right call for any Los Angeles home with water staining around the interior casing.
View Full Frame Window ReplacementRetrofit keeps your existing interior trim and drywall intact while replacing the sash and jamb liner. It's faster and cheaper than full-frame, and it's a good fit for 1980s and 1990s Los Angeles homes where the framing is still solid.
View Retrofit Window ReplacementInsert windows drop into the existing wood frame with minimal disruption. Ideal for condos and apartments in Santa Monica and Beverly Hills where HOA rules limit exterior changes. We measure the existing pocket to the sixteenth of an inch to guarantee a clean fit.
View Insert Window ReplacementIf your frame is sound but the sashes are rotted or the glass is fogged, sash-only replacement saves 30 to 50 percent versus a full unit. We match the original profile and can replicate true divided lites on historic Los Angeles homes.
View Window Sash ReplacementDouble hung is the classic Los Angeles Craftsman and Victorian profile. Both sashes slide and tilt in for cleaning. We stock common sizes and can match original weight-and-pulley systems or upgrade to modern spiral balances.
View Double Hung Window ReplacementSingle hung units have a fixed upper sash and an operable lower sash. They cost less than double hung and work well on bedrooms and hallways where you don't need top ventilation. Popular on 1960s tract homes in the Valley.
