AfterWindows & Doors in Woodland Hills, CA
Window installation in Woodland Hills, CA means working with two forces most installers never face together: summer temperatures that routinely cross 110°F and hillside tracts inside California’s Very High Fire Hazard Severity Zone. Most homes here were built between the 1950s and early 1970s with single-pane aluminum sliding windows that were never designed for either condition. We replace those openings with dual-pane, fire-rated assemblies specified for the western San Fernando Valley’s thermal load and WUI code requirements. Call (509) 265-6387 for a written price before any work starts.
Why Woodland Hills Homes Are Different
Woodland Hills has the distinction of being one of the hottest urban neighborhoods in California. West-facing and southwest-facing facades take direct afternoon sun for hours at peak intensity, which is why single-pane west-facing rooms become uninhabitable in July and August. That heat load is compounded by Santa Ana wind events that funnel through this corridor and stress door threshold seals and weatherstripping at failure rates higher than coastal LA neighborhoods.
The hillside tracts near the Santa Monica Mountains foothills carry a second, harder requirement. Large portions of Woodland Hills fall within the Very High Fire Hazard Severity Zone. The 2018 Woolsey Fire burned directly through parts of this area, and the rebuilds and retrofits that followed are inspected under California’s Chapter 7A WUI requirements by the LA Department of Building and Safety. Standard residential window units without verified fire-rated glazing or tested door assemblies get red-tagged. Contractors who treat Woodland Hills like a standard valley job miss this compliance gap entirely. We don’t.
Our Main Woodland Hills Services
Two services carry the most weight in Woodland Hills: full door installations on homes where the original frames have warped under decades of thermal cycling, and complete window replacement on ranch-style and split-level tracts still running single-pane aluminum. Each has its own dedicated Woodland Hills page with pricing and scope detail.
Door Installation in Woodland Hills
Door installation in Woodland Hills involves more than swapping a slab. The original 1950s and 1960s frames on many homes have shifted with hillside settlement and decades of Santa Ana wind loading. We measure for frame squareness, threshold seal integrity, and fire-rated assembly compliance on every job. On hillside properties in the WUI zone, the door assembly itself must meet Chapter 7A testing standards, not just the glass. That means specifying tested door units, not whatever is in stock. See the full scope on our Door Installation in Woodland Hills page.
Window Replacement in Woodland Hills
Window replacement in Woodland Hills is driven by two failures: failed seals on original single-pane aluminum and thermal cracking in west-facing glass. Homes built from the 1950s through the early 1970s simply were not designed for 110°F summer peaks. The fix is low-SHGC dual-pane glazing sized to the opening, installed to current code. Hillside homes rebuilt after the Woolsey Fire require fire-rated, multi-pane tempered glazing that most valley-focused contractors do not carry. See the full breakdown on our Window Replacement in Woodland Hills page.

BeforeAfterWindow Installation in Woodland Hills
Window installation in Woodland Hills means replacing single-pane aluminum units on homes built from the 1950s through the early 1970s. The original glazing in these ranch and split-level tract homes was never rated for the valley’s 110°F summer peaks or the afternoon sun that hammers west-facing rooms. On hillside properties, the work also has to clear Chapter 7A fire-rated glazing requirements, which most standard window contractors in the valley are not set up to meet. We handle Window Installation from measured survey to final inspection with the price written before any work begins.
Single & Double Hung Windows
Signs you need it
Sashes that stick mid-travel, failed balances, or condensation collecting between panes on an older Woodland Hills home mean the original single-pane unit has reached the end of its service life.
What it costs in Woodland Hills
Single and double hung window installation in Woodland Hills typically runs $450 to $1,100 per window, with the high end driven by oversized openings and fire-rated glazing on hillside lots.
How we do it
We remove the old sash and frame, inspect the rough opening for rot or settlement, install the new unit with new flashing and insulation, and finish with interior trim and a documented photo record.
Horizontal Roller Windows
Signs you need it
Aluminum roller tracks that bind, fogged glass, or frames that rattle during Santa Ana wind events tell you the original rollers and seals have failed.
What it costs in Woodland Hills
Horizontal roller window installation in Woodland Hills generally lands between $400 and $950 per window, depending on frame size and whether the opening needs fire-rated glass.
How we do it
We pull the old frame, check the sill for slope and drainage, bed the new roller unit in sealant, and verify track alignment before buttoning up the interior.
3-Panel Sliding (3-Lite Roller) Windows
Signs you need it
Three-panel sliders that fall off their tracks or let dust in around the meeting rails have worn rollers and compressed weatherstripping that is past repair.
What it costs in Woodland Hills
3-panel sliding window installation in Woodland Hills ranges from $1,000 to $2,500 per opening, with the wide span reflecting the need for reinforced headers on some 1950s frames.
How we do it
We size the new three-lite unit to the existing rough opening, reinforce the header if required, set the frame square, and adjust all three sashes for equal reveal.
What Window Installation Costs in Woodland Hills
| Item | Typical range in Woodland Hills |
|---|---|
| Single & Double Hung Windows | $450 - $1,100 per window |
| Horizontal Roller Windows | $400 - $950 per window |
| 3-Panel Sliding (3-Lite Roller) Windows | $1,000 - $2,500 per opening |
How long does window installation take in Woodland Hills?
Most single-room window installations in Woodland Hills finish in one day, while full-home replacements run three to five days. Permits on hillside properties in the WUI zone can add inspection time. Call (509) 265-6387 for a written timeline.
Will the price change once work starts?
No. The price on your written quote is the price on your final invoice, unless we uncover hidden structural damage during tear-out and you approve a written change order. That’s Clause 1 and Clause 5 of the Haven Standard. Call (509) 265-6387 for an exact quote.
Impact Windows & Doors in Woodland Hills
Impact windows and doors in Woodland Hills serve two functions that overlap here more than anywhere else in LA. The Woolsey Fire burn zone and the surrounding Very High Fire Hazard Severity Zone require fire-rated, multi-pane tempered glazing by code. Santa Ana wind events through this corridor also demand glass that can take flying debris at high speed. We install Impact Windows & Doors from PGT, CGI, and ES Windows, specified by what the opening requires, not by what is in stock.
Impact-Resistant Windows
Signs you need it
Homes in Woodland Hills WUI zones that still carry single-pane glass will not pass a Chapter 7A inspection, and that is the first sign the opening needs impact-rated glazing.
What it costs in Woodland Hills
Impact-resistant window installation in Woodland Hills runs $900 to $2,600 per window, with laminated multi-pane assemblies on hillside lots at the top of that range.
How we do it
We measure the opening, specify the correct PGT, CGI, or ES Windows assembly for the WUI zone, remove the old unit, and install the new one with stainless hardware and fire-rated flashing.
Hurricane Impact Windows
Signs you need it
Windows that bow inward during Santa Ana gusts, or that sit on elevations where ember exposure is a real risk, belong in the hurricane-impact category for this city.
What it costs in Woodland Hills
Hurricane impact windows in Woodland Hills typically cost $1,100 to $2,800 per unit, driven by the heavier laminated glass and reinforced frame profiles required.
How we do it
We pull the existing frame, verify the rough opening will accept the thicker impact assembly, install with structural screws, and document the finished glazing for inspection records.
What Impact Windows & Doors Costs in Woodland Hills
| Item | Typical range in Woodland Hills |
|---|---|
| Impact-Resistant Windows | $900 - $2,600 per window |
| Hurricane Impact Windows | $1,100 - $2,800 per window |
| Impact Door Assemblies | $2,200 - $5,800 per opening |
Do Woodland Hills homes actually need impact windows?
If your home sits inside the Very High Fire Hazard Severity Zone, Chapter 7A requires fire-rated glazing that meets the same multi-pane tempered standard as impact glass. Outside that zone, impact windows are optional protection against Santa Ana debris. Call (509) 265-6387 to check your parcel.
What is the difference between fire-rated and impact-rated glass?
Fire-rated glass is tested for ember ignition resistance under WUI standards, while impact-rated glass is tested for missile strikes and pressure cycling. In Woodland Hills WUI zones, your windows need both ratings on the same lite. Call (509) 265-6387 for a free specification review.
Energy-Efficient Windows in Woodland Hills
Energy-efficient windows in Woodland Hills are not a comfort upgrade. They are a load calculation. West-facing rooms in this neighborhood can sit above 100°F for hours on a July afternoon, and single-pane glass does nothing to slow that heat. Low-SHGC dual-pane glazing is the fix that turns an unusable west bedroom into a living space. We install Energy-Efficient Windows with U-factor and SHGC ratings matched to the orientation of each opening.
Low-E & Argon Gas Glass
Signs you need it
Rooms that stay hot hours after the sun goes down, or glass that radiates heat at you from across the room, are running on old clear single-pane units with no low-E coating.
What it costs in Woodland Hills
Low-E and argon gas window installation in Woodland Hills ranges from $500 to $1,300 per window, depending on whether the frame is a retrofit or full replacement.
How we do it
We spec the low-E coating and argon fill by compass orientation, then install the insulated glass unit into a frame sized for the existing rough opening.
ENERGY STAR Replacement Windows
Signs you need it
Utility bills that spike in July and August, hot glass surfaces you can feel from three feet away, and drafts around the sashes all point to ENERGY STAR replacement windows.
What it costs in Woodland Hills
ENERGY STAR replacement windows in Woodland Hills run $550 to $1,450 per window, with the high end covering oversized west-facing openings.
How we do it
We measure each opening, select the right ENERGY STAR model for the southern California climate zone, and install with new insulation and weatherstripping throughout.
What Energy-Efficient Windows Costs in Woodland Hills
| Item | Typical range in Woodland Hills |
|---|---|
| Low-E & Argon Gas Glass | $500 - $1,300 per window |
| ENERGY STAR Replacement Windows | $550 - $1,450 per window |
| UV-Blocking & Fade Protection Glass | $500 - $1,250 per window |
How much do energy-efficient windows cut utility bills in Woodland Hills?
Most Woodland Hills homeowners see a 15 to 30 percent drop in summer cooling costs after replacing west-facing single-pane windows with low-SHGC dual-pane units. The exact figure depends on wall insulation and roof condition. Call (509) 265-6387 for a heat-load review.
Does the direction my windows face change the glass spec?
Yes. West- and southwest-facing openings in Woodland Hills need a lower SHGC to block afternoon solar gain, while east-facing windows can carry a higher SHGC without penalty. We spec glass by orientation on every job. Call (509) 265-6387 for details.
Sliding & Patio Doors in Woodland Hills
Sliding and patio doors in Woodland Hills take a beating from two directions: the thermal cycling of 40-degree overnight swings in summer, and Santa Ana winds that push threshold seals past their design limits. Many 1950s and 1960s ranch homes still carry the original aluminum sliders, now running on worn rollers with compressed weatherstripping. We replace them with Sliding & Patio Doors built for the valley’s specific wind and heat pattern.
Patio Doors
Signs you need it
Doors that need two hands and a hip to open, or gaps at the threshold where dust and heat come in, mean the rollers and seals have failed beyond adjustment.
What it costs in Woodland Hills
Patio door installation in Woodland Hills runs $1,400 to $3,800 per opening, depending on width and whether the new door needs a fire-rated assembly.
How we do it
We remove the old slider, verify the rough opening is square and level, install the new door on new rollers, and replace the threshold seal.
Impact Sliding Glass Doors
Signs you need it
Hillside homes in the WUI zone need an impact-rated sliding glass door to pass inspection, and split-level homes that face the canyon winds will fail their seals early without one.
What it costs in Woodland Hills
Impact sliding glass doors in Woodland Hills cost $2,200 to $5,800 per opening, driven by reinforced frames and laminated glass panels.
How we do it
We specify a tested assembly from PGT or CGI, pull the old frame, reinforce the rough opening, and install the new door with stainless hardware.
What Sliding & Patio Doors Costs in Woodland Hills
| Item | Typical range in Woodland Hills |
|---|---|
| Patio Doors | $1,400 - $3,800 per opening |
| Impact Sliding Glass Doors | $2,200 - $5,800 per opening |
| Sliding Glass Door Replacement | $1,200 - $3,400 per opening |
Are sliding doors in Woodland Hills required to be fire-rated?
Only if the home falls inside the Very High Fire Hazard Severity Zone. Those openings must carry a tested door assembly under Chapter 7A. Outside the zone, standard doors are permitted. Call (509) 265-6387 and we’ll check your parcel records.
Why do my current patio doors jam every summer?
Aluminum frames expand in the valley’s July heat, and if the original 1950s or 1960s installation did not allow for thermal movement, the door binds. The fix is a properly shimmed and flashed replacement. Call (509) 265-6387 for a free opening assessment.
Impact Garage Doors in Woodland Hills
Impact garage doors in Woodland Hills are not a niche product. Garages in this city face the largest wind-blown ember exposure of any opening on the house during Santa Ana events. A standard unrated garage door is the weakest point in a WUI-zone building envelope. We install Impact Garage Doors that meet wind-load code compliance and Chapter 7A assembly standards for homes in the Very High Fire Hazard Severity Zone.
Hurricane-Rated Garage Doors
Signs you need it
Garage doors that flex visibly during wind events, or that sit on hillside elevations where ember collection is serious, are candidates for hurricane-rated replacement.
What it costs in Woodland Hills
Hurricane-rated garage door installation in Woodland Hills runs $2,400 to $6,200 per opening, with double-wide doors at the upper end.
How we do it
We remove the old door and tracks, install the new rated door with reinforced hardware, and verify wind-load capacity against the site’s exposure.
Wind-Load Code Compliance
Signs you need it
If your garage door was installed before the current wind-load codes were adopted in this corridor, it likely will not pass inspection on a WUI-zone property.
What it costs in Woodland Hills
Wind-load code compliance retrofits in Woodland Hills run $1,800 to $4,500 per opening, including structural reinforcement and new rated door panels.
How we do it
We assess the existing opening, reinforce the jambs as required, install the rated door, and provide the documentation for inspection.
What Impact Garage Doors Costs in Woodland Hills
| Item | Typical range in Woodland Hills |
|---|---|
| Hurricane-Rated Garage Doors | $2,400 - $6,200 per opening |
| Wind-Load Code Compliance | $1,800 - $4,500 per opening |
| Energy-Efficient Garage Doors | $1,600 - $4,000 per opening |
Do garage doors need to be fire-rated in Woodland Hills?
If the garage is attached to a home inside the Very High Fire Hazard Severity Zone, the door assembly must meet Chapter 7A testing standards. That includes the panel construction and the perimeter sealing details. Call (509) 265-6387 to confirm your property’s zone.
How long does an impact garage door install take?
Most single-bay impact garage door installations in Woodland Hills finish in one day. Double-bay openings or structural reinforcement work can run two days. Call (509) 265-6387 for a written timeline on your opening.
Custom & Geometric Windows in Woodland Hills
Custom and geometric windows in Woodland Hills show up most often on two types of homes: mid-century customs in the hillside tracts, and post-Woolsey rebuilds that laid out openings for light, not for stock window sizes. Both require a fabrication partner who can produce odd-shaped units that still meet the area’s fire-rated glazing requirements. We handle Custom & Geometric Windows from ES Windows and CWS, built to the measured opening and delivered with the same WUI compliance documentation as any standard window.
Geometric & Shaped Windows
Signs you need it
Non-rectangular openings that were framed custom decades ago cannot be filled with stock units, and the original single-pane glazing is now failing.
What it costs in Woodland Hills
Geometric and shaped window installation in Woodland Hills runs $1,200 to $3,600 per opening, with odd angles and small radii driving fabrication cost.
How we do it
We template the exact opening, fabricate the unit to the template, and install with flashing and sealant matched to the WUI zone requirements.
Arched & Curved Windows
Signs you need it
Arched windows with cracked single-pane glass, or that have lost their seal and fog between the panes, need a custom-curved replacement unit.
What it costs in Woodland Hills
Arched and curved window installation in Woodland Hills costs $1,500 to $4,200 per opening, with large radii at the higher end.
How we do it
We measure the radius directly, fabricate the curved insulated glass unit, and install it into the original masonry or wood opening with new stops.
What Custom & Geometric Windows Costs in Woodland Hills
| Item | Typical range in Woodland Hills |
|---|---|
| Geometric & Shaped Windows | $1,200 - $3,600 per opening |
| Arched & Curved Windows | $1,500 - $4,200 per opening |
| Custom Impact Windows | $1,400 - $4,800 per opening |
Can custom windows meet Woodland Hills fire code?
Yes. Custom and geometric windows can be fabricated with fire-rated, multi-pane tempered glazing that meets Chapter 7A standards. The key is specifying the rating at fabrication, not trying to modify a stock unit. Call (509) 265-6387 for a specification review.
How long do custom windows take in Woodland Hills?
Custom and geometric windows typically run four to eight weeks from template to delivery, depending on the shape and the glass ratings required. Standard windows are usually two to three weeks. Call (509) 265-6387 for a written lead time on your opening.

Two things push prices up in Woodland Hills. The first is fire-rated glazing on properties inside the Very High Fire Hazard Severity Zone, which adds cost to every lite. The second is hillside access and structural reinforcement on older frames. What does not push price up is the quoting process: the measured survey and the written quote are the same document, and that price is fixed before any work starts.
