Call (888) 635-0804 and a live person answers, 24/7, not a voicemail tree.
Why TruePane Windows & Doors Is Westlake Village’s Preferred Window Installation Company
We have worked on enough 1970s and 1980s tract homes along Lindero Canyon Road, Three Springs Drive, and the streets off Westlake Boulevard to know what we will find before the first window comes out. Original aluminum sliders with corroded frames. Single-pane glass that turns a west-facing living room into an oven by 2:00 p.m. in August. Flashing tape that has dried to powder. Westlake Village homeowners tend to stay in their homes for decades, which means the windows we pull are usually the ones the builder installed forty or fifty years ago.
Dale Kessler founded TruePane in 2008 on a simple rule: if the pane is not true, the job is not done. Our installers are background-checked, uniformed, and trained as journeymen, not day laborers picked up for a weekend job. We measure every opening twice, quote manufacturer lines side by side on paper, and register both warranty layers before the truck leaves your driveway. That is The Keystone Standard, and it is in writing on every Westlake Village job.
We are not the cheapest bid you will get. We are the last call you should need to make, because the work is done right and we stand behind it. The Done Right Promise means if something is not right, we make it right, no paperwork fight and no fine print that covers neither.
Our Window Installation Services in Westlake Village
Here is what we install most often in Westlake Village, and why it matters in this specific climate and fire zone. Our Window Installation team handles every job from a single retrofitted opening to a full-house replacement.
Casement Windows
Casement windows are popular in Westlake Village because they seal tightly against wind, which matters when Santa Ana gusts come downslope off the Santa Monica Mountain foothills. We see a lot of 1970s single-pane casements that have racked out of square from repeated wind events, so the sash no longer seats against the jamb. A new casement with multi-point locking hardware and a compression seal closes that gap permanently. In Westlake Village, casement window installation typically runs $750-$1,600 per opening depending on size and frame material.
Fixed and Picture Windows
Fixed picture windows are common on the golf course side of Westlake Village and in homes positioned to capture the lake view. The catch is that a non-openable window still has to meet Chapter 7A fire code in this Very High Fire Hazard Severity Zone. That means multi-pane tempered glass, and in many cases ember-resistant screening even on a fixed unit. We handle that as standard practice, not an upsell. Picture window work in Westlake Village runs $500-$1,800 per opening depending on glass size and fire-code requirements.
Sliding Windows
The original aluminum sliders from Westlake Village’s 1968-1985 buildout are the single most common window we replace. The aluminum frames corrode after decades of heat cycling, the rollers grind down, and the insulated seals fail. What we find when we pull one out is often worse than the homeowner expects, which is why we write allowances into the contract and get written approval before we cut anything. Sliding window replacement in Westlake Village typically runs $600-$1,300 per opening.
Single and Double Hung Windows
Double hung windows show up a lot in the two-story colonials and traditional homes off Triunfo Canyon Road and around the North Ranch area. The challenge in this climate is the seasonal wood-frame movement. Dry heat causes wood frames to shrink and gap, so the sashes bind in July and drafts pour in at night. We size hung windows with enough clearance to handle Westlake Village’s heat differentials without rattling in the wind. Single and double hung installation runs $700-$1,500 per opening in Westlake Village.

Trusted Brands We Service in Westlake Village
TruePane is an authorized installer for more than a dozen manufacturer lines, including, PGT, and CGI. For Westlake Village’s fire-zone requirements, we often specify CGI impact-rated products, ES Windows for custom architectural profiles, and ECO Window Systems for cost-conscious retrofits that still meet code. We register both warranty layers in writing before the truck leaves the driveway, so if a seal fails or hardware binds, the fix is covered, in writing, with durations stated. That is how a square deal works.
Common Window Installation Problems We See in Westlake Village Homes
Here is what our crews actually find behind the walls of Westlake Village homes, the failures that drive a quote up and the ones that catch out-of-area contractors off guard:
- Fogged insulated glass in original aluminum sliders. The argon is gone, the seal has failed, and the homeowner notices the haze between the panes but assumes it is cosmetic until the summer cooling bill arrives. By the time we pull the sash, the frame is often corroded enough that a retrofit patch would be throwing good money after bad.
- Racked casement openings from Santa Ana wind cycles. Decades of downslope gusts off the foothills push the entire window frame out of square. The sash no longer seats, drafts pour in, and the only real fix is a full-frame replacement with the rough opening corrected.
- Wood frame shrinkage and gapping. Westlake Village’s 100 degree-plus summer days and cool nights cycle wood door and window frames through repeated expansion and contraction. The result is gaps that open seasonally, hardware that binds, and weatherstripping that fails twice as fast as it should.
- HOA-driven stop-work orders. Westlake Village’s planned-community covenants govern exterior appearance closely. Skip the HOA approval on a double-hung replacement and the association can halt the project for six weeks while the permit clock runs. We handle the HOA submittal before we pull the first window.

FAQs - Window Installation in Westlake Village
Because Westlake Village sits inside a Very High Fire Hazard Severity Zone, and local building officials enforce California Chapter 7A WUI code on nearly every window replacement, even a single opening. That means multi-pane tempered glass, non-combustible or fire-rated frame materials, and in many cases ember-resistant screening. A contractor from Thousand Oaks or Calabasas who does not work FHSZ homes regularly may not flag this, and it will surface at inspection. We price it up front and write it into the contract.
Usually three things: corroded aluminum frames from decades of inland-valley heat cycling, dried-out flashing tape that has lost all adhesion, and a rough opening that has racked slightly out of square from Santa Ana wind stress. The framing correction is the part most quotes ignore, and it is the part that turns a two-day retrofit into a two-week full-frame job. We inspect the opening before we price, and any surprise is priced and approved in writing before we cut a single stud.
We prepare and submit the application for you. Westlake Village’s covenants govern exterior appearance tightly, so the HOA wants to see frame color, window style, grille pattern, and sometimes the manufacturer’s cut sheet before they approve. We have done this enough times to know what the architectural review boards off Lindero Canyon and Westlake Boulevard will accept. The HOA process usually adds two to six weeks, and we build that into the schedule so the permit clock does not become your problem.
The window frame has likely racked out of square. Repeated Santa Ana wind events, especially on west- and north-facing exposures that catch downslope gusts off the Santa Monica Mountain foothills, push the entire window assembly out of true. The sash no longer seats against the jamb, so drafts pour in even though the weatherstripping looks intact. The fix is a full-frame replacement that corrects the rough opening, not a new piece of weatherstripping. Call (888) 635-0804 and we will inspect it for free.
In most Westlake Village homes, yes. The Chapter 7A inspection requirement applies to the glazing and frame regardless of whether the sash operates. A fixed window with single-pane or standard annealed glass can still fail under radiant heat and wind-driven ember exposure, which is exactly what the code is designed to prevent after the Woolsey Fire. We specify the screening as standard practice on FHSZ jobs, not as a line-item upsell.
