AfterWindows & Doors in Los Angeles, CA
Window installation in Los Angeles starts with a written price you keep, and it almost always runs into one of three local realities: a hillside WUI fire code, an HPOZ profile match, or an original steel casement rusted through from the marine layer. We install and replace windows and doors across Los Angeles under the Haven Standard, which means the measured survey and the written quote are the same document. If you are pricing a replacement in Silver Lake, a stucco tract house in the Valley, or a 1920s Spanish Colonial in Hancock Park, call (509) 265-6387 and we will put the numbers on paper before any tool is lifted.
Why Los Angeles Homes Are Different
Los Angeles runs on two parallel building codes that most neighboring cities only brush against. The first is California Title 24, which sets SHGC and U-factor thresholds by climate zone. Los Angeles splits into Zones 9 and 10, so a window that passes in the Valley may fail on the fog-heavy westside. The second is the CAL FIRE Wildland-Urban Interface map, which puts the Hollywood Hills, Laurel Canyon, Pacific Palisades, Topanga Canyon, and the foothill corridors above the San Fernando Valley under fire-rated glazing and non-combustible frame requirements. A routine slider swap in one of those neighborhoods is not routine.
The housing stock makes it more layered. Silver Lake, Echo Park, and Los Feliz are full of 1920s through 1940s Spanish Colonial Revival and Craftsman bungalows with steel casement windows that corrode where paint fails. The San Fernando Valley’s 1960s and 1970s tract homes carry original aluminum sliders that seize at the frame-to-stucco seam. And in Historic Preservation Overlay Zones like Hancock Park, Angelino Heights, and Windsor Square, LADBS will reject a replacement window that does not match the original muntin profiles and divided-light patterns. None of this is a theory; it shows up on the first site visit.
Our Main Los Angeles Services
Two jobs dominate the calls we get from Los Angeles homeowners, and each has its own dedicated page with deeper pricing and local detail.
Door Installation in Los Angeles
Door installation in Los Angeles runs from entry door replacements on 1920s bungalows to new construction openings on hillside lots where WUI code dictates the frame material. Salt-air corrosion on westside homes eats aluminum threshold hardware faster than homeowners expect, and Santa Ana thermal cycling loosens weatherstripping on inland-facing slopes. We measure, write the price, and install against the same document. Full detail is on the Door Installation in Los Angeles page.
Window Replacement in Los Angeles
Window replacement in Los Angeles is rarely as simple as pulling one sash and setting another. HPOZ districts require profile-matched muntins and glass-to-frame ratios, and WUI zones require impact-rated or tempered multi-pane glazing with non-combustible frames. The westside marine layer and Valley heat do different things to the same product line, so we specify by opening, not by inventory. See the Window Replacement in Los Angeles page for full pricing.

BeforeAfterWindow Installation in Los Angeles
Window installation in Los Angeles is the job most homeowners call about first, and it is where the city’s building layers hit hardest. A 1926 casement in Los Feliz, a 1970 aluminum slider in Sherman Oaks, and a new opening on a Topanga hillside all start the same way: with a written survey that names the frame condition, the glazing spec, and the number we will hold to. That is Haven Clause 1, and it is why our Window Installation work always begins with a document you keep.
Single & Double Hung Windows
Signs you need it
Sash cords snap, counterweights detach, and the lower sash on a double hung stops staying up, especially in pre-1940 Los Angeles homes where original wood windows have cycled through decades of coastal humidity and inland heat.
What it costs in Los Angeles
Single and double hung window installation in Los Angeles typically runs $650 to $1,200 per opening, depending on frame material and whether the home sits in an HPOZ that requires profile-matched replacement.
How we do it
We pull the interior stop, remove the old sash and counterweight system, square the rough opening, flash the sill and jambs, set the new unit, and leave the measured survey, installation photo record, and written warranty with you at the end of the day.
Horizontal Roller Windows
Signs you need it
The roller track fills with dust and the sash starts to drag or bind, a common failure on 1960s and 1970s aluminum sliders across the San Fernando Valley and the stucco tracts of West LA.
What it costs in Los Angeles
Horizontal roller window installation in Los Angeles typically runs $550 to $950 per opening, with the higher end covering WUI-compliant frame materials in hillside zones.
How we do it
We measure the existing track, specify a replacement that matches the sightline and operational style, remove the old frame to the rough opening, install new flashing and the new unit, and document every step in the photo record you receive.
What Window Installation Costs in Los Angeles
| Item | Typical range in Los Angeles |
|---|---|
| Single & double hung window replacement | $650 – $1,200 per opening |
| Horizontal roller window replacement | $550 – $950 per opening |
| Full window installation, stucco-frame home | $700 – $1,300 per opening |
How long does window installation take in Los Angeles?
Most single-opening replacements in Los Angeles are completed in one day. Full-home window installation runs three to seven days depending on the number of openings and whether the home is in an HPOZ or WUI zone. Call (509) 265-6387 for a written schedule with your estimate.
Does LADBS need to inspect window installation?
Yes in most cases. Los Angeles requires permits for window replacement when the opening is being altered or the home falls under WUI or HPOZ rules. We pull the permits, schedule the inspection, and the photo record from the job travels with the permit file. Call (509) 265-6387 for a free estimate that includes permit scope.
Impact Windows & Doors in Los Angeles
Impact windows and doors in Los Angeles are no longer a coastal-only product. The CAL FIRE WUI map now covers the Hollywood Hills, Laurel Canyon, Pacific Palisades, Topanga, and the foothill corridors above the San Fernando Valley, and post-Palisades and Eaton Fire rebuilding has made fire-rated or tempered multi-pane glazing the default conversation in the trade. Our Impact Windows & Doors work is specified by the opening and the code, not by margin.
Impact-Resistant Windows
Signs you need it
You live in a WUI-designated hillside neighborhood, your insurance carrier now requires wind-borne debris protection, or your existing single-pane windows fail the Title 24 review your rebuild triggered.
What it costs in Los Angeles
Impact-resistant window installation in Los Angeles typically runs $900 to $1,700 per opening depending on the frame material and whether the unit is specified for Zone 9 or Zone 10 exposure.
How we do it
We confirm the WUI designation and climate zone on the measured survey, specify the impact-rated glazing and frame combination that carries the proper certification, install the unit to the manufacturer’s wind-load spec, and hand you the photo record and paperwork the permit requires.
Hurricane Impact Windows
Signs you need it
Your opening faces a sustained wind or wind-borne debris exposure, or your rebuilt home on a hillside corridor now carries a requirement for hurricane-rated glazing even though Los Angeles rarely sees the storm itself.
What it costs in Los Angeles
Hurricane impact window installation in Los Angeles typically runs $950 to $1,800 per opening when the unit is specified for the wind-load and debris-impact standards that WUI corridors require.
How we do it
We source the hurricane-rated unit from the manufacturer line that carries the correct certification, install it with the required anchoring and glazing tap, and document every step so the final invoice and the permit file match the written quote.
What Impact Windows & Doors Costs in Los Angeles
| Item | Typical range in Los Angeles |
|---|---|
| Impact-resistant window replacement | $900 – $1,700 per opening |
| Hurricane impact window installation | $950 – $1,800 per opening |
| Impact door replacement | $1,400 – $2,600 per opening |
Will impact windows in Los Angeles block UV fading?
Yes. Impact-rated laminated glass filters 99% of UV, which is the main driver of floor and furnishing fade in Los Angeles homes that get direct sun through large openings. Call (509) 265-6387 for a free estimate that includes the glazing spec in writing.
Do I have to be in a fire zone to need impact windows?
No. Many Los Angeles homeowners outside WUI boundaries install impact windows for the UV filtration, noise reduction on busy streets, and insurance documentation. The written quote names the spec either way. Call (509) 265-6387 for an exact quote.
Energy-Efficient Windows in Los Angeles
Energy-efficient windows in Los Angeles do two different jobs depending on which side of the 405 you live on. The westside marine layer means U-factor matters less in Venice than it does in Woodland Hills, while SHGC drives the math everywhere the sun sits on the glass for six hours a day. Our Energy-Efficient Windows are specified by opening orientation and zone, not by the brochure.
Low-E & Argon Gas Glass
Signs you need it
Rooms on the south and west side of your Los Angeles home heat up by mid-afternoon, or your current glass carries no visible low-E coating and the utility bill tracks the thermostat setting.
What it costs in Los Angeles
Low-E and argon gas window replacement in Los Angeles typically runs $600 to $1,100 per opening, with double-pane low-E units at the lower end and triple-pane argon at the higher end.
How we do it
We read the SHGC and U-factor numbers off the measured survey, specify the low-E coating and gas fill that matches the opening’s orientation, install the unit, and leave the glazing spec in the written record you keep.
ENERGY STAR Replacement Windows
Signs you need it
Your windows are single-pane originals from the 1920s through 1970s, and the southern-facing rooms gain 10 to 15 degrees between morning and late afternoon in the San Fernando Valley or the eastside flats.
What it costs in Los Angeles
ENERGY STAR replacement window installation in Los Angeles typically runs $650 to $1,250 per opening depending on frame material and climate zone, with Zone 10 units on the westside at the lower bound and Zone 9 Valley units at the higher bound.
How we do it
We specify the ENERGY STAR-rated unit that hits the correct U-factor and SHGC for the zone, pull the old sash and frame, flash and set the new unit, and include the performance numbers in the written job record.
What Energy-Efficient Windows Costs in Los Angeles
| Item | Typical range in Los Angeles |
|---|---|
| Low-E / argon gas replacement windows | $600 – $1,100 per opening |
| ENERGY STAR replacement windows | $650 – $1,250 per opening |
| Insulated laminated glass replacement | $700 – $1,300 per opening |
Which is more important in Los Angeles, U-factor or SHGC?
SHGC matters more in Los Angeles because solar heat gain, not winter heat loss, drives the energy math. In Zone 9 Valley homes we specify lower SHGC; on the westside the U-factor carries more weight. Call (509) 265-6387 for a free estimate that names both numbers.
Will energy-efficient windows reduce LA noise?
They reduce it, but they do not eliminate it. Laminated glass cuts mid- and high-frequency street noise best, while standard double-pane low-E helps with heat. The written quote names the glazing composition. Call (509) 265-6387 for an exact spec.
Sliding & Patio Doors in Los Angeles
Sliding and patio doors in Los Angeles fail in predictable ways: aluminum tracks corrode under the westside marine layer, rollers seize from dust and runoff, and Valley heat warps vinyl frames until the panel no longer seals. A new patio door in Los Angeles also has to meet whatever WUI or HPOZ rule applies to the opening. That is why our Sliding & Patio Doors paperwork starts with a written price and the measured survey, never a verbal range.
Patio Doors
Signs you need it
The door sticks, the track fills with grit, the lock no longer aligns, or the panel has dropped a quarter inch so the weatherstripping gaps open at the corner.
What it costs in Los Angeles
Patio door replacement in Los Angeles typically runs $1,400 to $2,600 per opening including the frame, hardware, and stucco return work on older Spanish Colonial and Craftsman homes.
How we do it
We measure the slab, track, and header, specify the door by opening width and code zone, remove the old frame cleanly, set and flash the new unit, and document the level and plumb readings in the photo record you keep.
Impact Sliding Glass Doors
Signs you need it
You are in a hillside WUI corridor or your insurance carrier now requires impact-rated glazing on the largest glass opening in the house.
What it costs in Los Angeles
Impact sliding glass door installation in Los Angeles typically runs $2,200 to $4,000 per opening depending on panel size, wind-load rating, and whether the home sits in a Zone 9 or Zone 10 exposure.
How we do it
We confirm the wind-load and debris-impact standard on the written survey, source the impact-rated door from the manufacturer line that carries the certification, install the track and panel to spec, and include the certification documents in the final record.
What Sliding & Patio Doors Costs in Los Angeles
| Item | Typical range in Los Angeles |
|---|---|
| Patio door replacement | $1,400 – $2,600 per opening |
| Impact sliding glass door installation | $2,200 – $4,000 per opening |
| Sliding glass door glass-only replacement | $350 – $800 per panel |
How long does patio door replacement take in Los Angeles?
Most patio door replacements are completed in one day. Impact-rated doors take longer to source, usually three to five weeks from order to install. Call (509) 265-6387 for a written timeline with your estimate.
Will the stucco around my patio door crack during replacement?
We cut back the stucco cleanly, set the new frame, and leave a stable return that painters can finish directly. The photo record documents the cut before and after. Call (509) 265-6387 for a free estimate.
Impact Garage Doors in Los Angeles
Impact garage doors in Los Angeles are a WUI-driven product now, and the conversation changed after the Palisades and Eaton fires. Hillside homes in the WUI designation now carry requirements for wind-load-rated garage doors with non-combustible panel and track materials, and the permit office will ask for the certification paperwork. Our Impact Garage Doors work includes that documentation on every job.
Hurricane-Rated Garage Doors
Signs you need it
Your garage faces the dominant wind corridor on a hillside lot, or your rebuild plan now lists a wind-load rating for the garage opening as a condition of permit approval.
What it costs in Los Angeles
Hurricane-rated garage door installation in Los Angeles typically runs $2,800 to $5,500 per opening depending on panel material, wind-load rating, and whether the track system is standard or heavy-gauge.
How we do it
We measure the opening, specify the wind-load-rated door and track system, install the panel set and hardware to the manufacturer’s spec, and put the certification paperwork in the photo record you receive.
Garage Door Replacement
Signs you need it
Panels dent or separate, the spring system no longer lifts the door evenly, or the existing door carries no rating and the home now sits inside an expanded WUI boundary.
What it costs in Los Angeles
Garage door replacement in Los Angeles typically runs $1,800 to $3,800 per opening for a standard two-car door, with wind-load-rated panels pushing the number to the upper bound.
How we do it
We document the existing spring tension, release and replace the door sections and track, set the new panel stack, test the balance, and hand you the written warranty and photo record.
What Impact Garage Doors Costs in Los Angeles
| Item | Typical range in Los Angeles |
|---|---|
| Hurricane-rated garage door installation | $2,800 – $5,500 per opening |
| Standard garage door replacement | $1,800 – $3,800 per opening |
| Wind-load code compliance upgrade | $1,200 – $2,500 per opening |
Do I need a permit for an impact garage door in Los Angeles?
Yes. The permit is tied to the WUI wind-load rating, and LADBS will ask for the certification paperwork at inspection. We pull the permit and include the documents in the final record. Call (509) 265-6387 for a free estimate.
Can you match my existing garage door panels?
We match the panel profile, color, and sightline where the manufacturer still produces the line. If the line is discontinued, we specify the closest match and name it in writing. Call (509) 265-6387 for a quote.
Custom & Geometric Windows in Los Angeles
Custom and geometric windows in Los Angeles tend to show up in two places: original 1920s through 1940s homes with arched and shaped openings, and new hillside builds where the architect drew a window that no stock line carries. The HPOZ layer makes it harder, because the replacement has to match the original muntin profile and glass-to-frame ratio or LADBS will reject it. Our Custom & Geometric Windows are sourced and built to the opening, not picked from inventory.
Arched & Curved Windows
Signs you need it
The arched unit in a Hancock Park or Windsor Square home has a failed seal or a rusted steel frame, and a rectangular replacement is not an option under HPOZ review.
What it costs in Los Angeles
Arched and curved window replacement in Los Angeles typically runs $1,800 to $3,500 per opening depending on the radius, glazing, and whether the divided-light pattern has to be true SDL to pass review.
How we do it
We take a template of the radius and muntin pattern, specify the unit with the correct glass-to-frame ratio and exterior stop, order from the manufacturer line that carries the profile, and install with the measured survey as the control document.
Oversized Openings
Signs you need it
The opening exceeds 40 square feet of glass or spans a structural header, and the code now requires tempered or laminated glazing and possibly a heavier frame than the original carried.
What it costs in Los Angeles
Oversized custom window installation in Los Angeles typically runs $2,000 to $4,500 per opening depending on glass area, glazing type, and whether the unit is impact-rated for a WUI location.
How we do it
We survey the header and load path, specify the glazing and frame that meet the structural and code requirements, order the custom unit, and install it with the header reading and photo record attached to the file.
What Custom & Geometric Windows Costs in Los Angeles
| Item | Typical range in Los Angeles |
|---|---|
| Arched & curved window replacement | $1,800 – $3,500 per opening |
| Geometric / shaped custom window | $1,500 – $3,000 per opening |
| Oversized custom window installation | $2,000 – $4,500 per opening |
How do you match an original muntin profile in an HPOZ?
We template the existing muntin bar, specify a true divided light unit with matching exterior stop, and submit the spec to LADBS for review before ordering. Call (509) 265-6387 for a free estimate that includes the HPOZ documentation.
Can you build a window to match a template I provide?
Yes. We work from the architect’s drawing or a field template our surveyor takes on site, and the written quote names the exact radius, glazing, and divided-light pattern. Call (509) 265-6387 for a custom quote.

"The survey measurements and the quote were the same piece of paper. Nothing changed on install day, which is not what happened with the two other companies we had out."
- Annette R."Replaced eight windows. They showed me the U-factor on the units they were actually fitting rather than the brochure numbers."
- Kofi B."They photographed the rotten sill they found under the old frame before replacing it, and the extra cost was agreed in writing before they carried on."
