Fast, Reliable Window Installation Across West Hollywood
Window installation in West Hollywood means working around rent-stabilized units, design review boards, and 1920s steel casements that have been holding on for a century. The work is different here than it is ten minutes east. We know the difference because we’ve been in these buildings, on these streets, and in front of the city’s Design Review process more times than we can count. If you own or manage a property in West Hollywood and need windows replaced, call (888) 635-0804 for a free estimate. A real person answers, and we’ll talk through your building, your timeline, and what the city will ask for before anyone touches a window.
What sets West Hollywood apart from every other city in Los Angeles County is this: nearly all of its multi-family housing stock was built before 1979. That puts almost every apartment building here under the city’s Rent Stabilization Ordinance. A window replacement in an RSO unit is not a walk-in, swap-the-sash job. It requires written tenant notification, coordinated access, and often a trip through Design Review. We handle all of that as part of the job, not as an afterthought. You can read more about how we approach Window Installation across all our service areas, but this page is specifically about West Hollywood.
Why TruePane Windows & Doors Is West Hollywood’s Preferred Window Installation Company
TruePane has the kind of local reputation that only comes from doing the work and standing behind it. Dale Kessler founded this company in 2008 on a rule that still hangs on the whiteboard: if the pane is not true, the job is not done. That rule governs every install we do in West Hollywood, from a single casement in a courtyard apartment on Havenhurst Drive to a full sliding-window replacement in a Fountain Avenue rental building. We are not the cheapest bid in the room. We are the last call a homeowner or landlord needs to make, because we put both warranty layers in writing and register them before the truck leaves the driveway.
West Hollywood customers keep our crews busy because we understand the RSO, the Design Review process, and Title 24 requirements in Climate Zone 9. That is not marketing language. It is the difference between a permit that sails through and a stop-work order. Our technicians are background-checked, uniformed, and trained to measure every opening twice. We quote manufacturer lines side by side on paper so you see exactly what you are buying. And our Done Right Promise means if something is off, we come back and fix it. No paperwork fights, no arguing.
Our Window Installation Services in West Hollywood
Most of the windows we install in West Hollywood fall into a few categories, driven by the city’s architectural character and the practical realities of its housing stock. Here is what we do most often, and how it applies specifically to this city.
Casement Windows
Casement windows are common in West Hollywood’s Spanish Colonial and Streamline Moderne buildings from the 1920s through the 1940s. Original steel casements are beautiful but decades past useful life. We replace them with custom units that match the original sight lines closely enough to satisfy Design Review, while upgrading to dual-pane, low-e, argon-filled insulated glass. A typical casement replacement in a West Hollywood apartment building runs $900-$2,400 per opening, depending on size, material, and whether the surrounding stucco needs repair.

Fixed & Picture Windows
Fixed and picture windows are popular in the Mid-Century Modern apartment buildings and condos along corridors like Sweetzer Avenue and the Sunset Strip. These windows frame views and bring in daylight, but old single-pane units leak conditioned air and let in street noise. We install fixed windows with modern thermal barriers and upgraded framing. In West Hollywood, expect to pay $700-$1,800 per fixed window, with larger picture windows running higher depending on glass area and structural requirements.

Sliding Windows
Sliding windows dominate 1950s and 1960s apartment stock in West Hollywood, especially in the low-rise stucco buildings along Fountain Avenue. The original aluminum sliders are often corroded at the track, fogged between the panes, and impossible to seal against drafts. We replace them with thermally broken aluminum or vinyl sliders sized to fit existing openings. A standard sliding window replacement here typically runs $850-$2,200 per unit. Two-lite and three-lite configurations cost more.

Single & Double Hung Windows
Single and double hung windows show up in West Hollywood’s Craftsman and transitional buildings, though they are less common than casements and sliders. When we install them, we match the original proportions and muntin profiles so the facade keeps its character. This matters because West Hollywood Design Review will flag mismatched window proportions on a permit submittal. Plan on $800-$2,000 per opening for single and double hung work in this city, with custom muntins adding to the cost.

Trusted Brands We Service in West Hollywood
We are an authorized installer for, PGT, CGI, and ES Windows, among others. For West Hollywood’s older buildings we frequently work with CGI, ES Windows, and ECO Window Systems because their product lines offer the narrow sight lines and custom profiles that Design Review wants to see on a 1920s Art Deco or Streamline Moderne facade. We keep local stock and established supply channels for these brands, which means faster turnaround when a West Hollywood building needs matching replacements on short notice. We quote manufacturer lines side by side on paper, so the decision is yours with full visibility into what each option costs.
Common Window Installation Problems We See in West Hollywood Homes
Opening up an older West Hollywood building always turns up something. Here is what we find most often, and how it affects a window job:
- Corroded steel jamb anchors in pre-1960 buildings. The original steel window frames on Fountain Avenue and Havenhurst Drive are often held in with anchors that have rusted to nothing. Once the old window is out, the opening needs anchor replacement before a new unit can go in. If this is not caught in the pre-inspection, it becomes a stop-work order and an unplanned structural permit.
- RSO tenant-notification compliance gaps. In any rent-stabilized unit in West Hollywood, the city requires written tenant notification before work begins. If the dates are not logged, the permit can be voided and the city can issue fines under the Rent Stabilization Ordinance. We handle the paperwork and the scheduling, and we keep a paper trail for every unit.
- Design Review rejection for off-the-shelf window proportions. A vinyl double-hung off the shelf does not match an Art Deco or Spanish Colonial facade. Design Review will reject it, and the landlord eats a tear-out and refit. We submit custom sight-line-matched units the first time, informed by what has passed review on similar buildings in West Hollywood.
- Title 24 SHGC failures on single-pane replacements. West Hollywood sits in Climate Zone 9, where Title 24 sets specific Solar Heat Gain Coefficient requirements. Single-pane glass does not meet the threshold. Any permitted replacement here effectively requires dual-pane, low-e glass. Landlords who assume they can stay with single-pane learn this at permit review. We educate before we quote, so there is no surprise.
Pricing for Window Installation in West Hollywood, CA
Window installation in West Hollywood runs higher than in neighboring Los Angeles for a simple reason: this city’s design review and RSO requirements add real steps that cheaper operators skip. A single casement replacement in a rent-stabilized courtyard building may run $900-$2,400. A sliding window in a 1960s Fountain Avenue apartment falls in the $850-$2,200 range. Fixed and picture windows run $700-$1,800. Labor for an RSO-compliant job, including tenant notification and coordinated access scheduling, typically adds $150-$400 per unit depending on the building. These are honest ranges for this market, not teaser prices. We give written, line-item quotes before any work starts, and we do not change the number once the job begins. Call (888) 635-0804 to schedule a free estimate for your West Hollywood property.
One point worth stating clearly: in West Hollywood, the cheapest bid is usually the most expensive one. A contractor who skips the pre-inspection, ignores RSO tenant rules, or submits an off-the-shelf window that Design Review rejects is going to cost you more in stop-work orders, refits, and city fines than the difference between their number and ours. A square deal means the price is the price, and the work is done right the first time.

FAQs - Window Installation in West Hollywood
Yes, in most cases. West Hollywood requires Design Review for exterior changes to buildings subject to the Rent Stabilization Ordinance, which covers nearly all pre-1979 multi-family stock. A single window replacement changes the exterior appearance, so the city wants to see that the new unit matches the original proportions, sight lines, and material character. We prepare the submittal with that in mind from the first measurement. Call (888) 635-0804 if you need help navigating the process for your building.
We coordinate directly with tenants, provide written notice with the required timing, and schedule work around their availability to the extent the building allows. The city requires documentation of tenant notification for RSO units, and we keep a paper trail for every unit we touch. This is standard practice for us on Sweetzer Avenue and throughout West Hollywood, not an add-on service. Call (888) 635-0804 to discuss the access logistics for your building.
No. Title 24 sets maximum Solar Heat Gain Coefficient thresholds for replacement windows in Climate Zone 9, which covers West Hollywood. A high-SHGC window that lets too much solar heat through will fail the compliance check. The short version is that dual-pane, low-e glass is effectively required on any permitted replacement here. We quote compliant glass packages from the start, so there is no failed inspection. Call (888) 635-0804 for specifics on your building’s requirements.
Fogging means the insulated glass unit’s seal has failed, and the window is no longer providing any real thermal performance. For a 1950s aluminum slider in West Hollywood, it also means the frame is probably corroded at the track and the unit is due for full replacement, not just a glass swap. Replacing the sash or the entire window with a Title 24-compliant unit is the standard fix. Call (888) 635-0804 for an assessment of what your building’s sliders actually need.
Not always, but the replacement has to match the original sight lines and proportions closely enough to satisfy Design Review. On Havenhurst Drive, we replaced a 1920s courtyard apartment’s original steel casements with custom aluminum-clad units after the city flagged a first submittal for too-wide frames. Our crew worked around tenant schedules under RSO rules, used flashing tape and low-E argon-filled insulated glass units, and got final sign-off because the new sash profiles were indistinguishable from the old steel. That is the standard, and it is achievable. Call (888) 635-0804 to talk through what your building needs.
We pre-inspect every opening before we write the quote. On a 1960s Fountain Avenue building, that means checking for corroded steel jamb anchors, undersized framing, and failed waterproofing behind the original window. If we find something, it becomes a written allowance in the contract, not a surprise. And if we do uncover something unexpected mid-job, we stop, price it, and get your written approval before touching it. No change orders that you did not sign off on. Call (888) 635-0804 to schedule a pre-inspection.
West Hollywood is the only city where a window replacement spans rent-stabilization law, historic preservation review, and California’s strictest energy code, all within a 1.9-square-mile footprint. That combination is real, and it shapes every job we do here. If you own a building on Havenhurst, Sweetzer, or Fountain, or anywhere else in the 90069, we know what your windows are up against. Call (888) 635-0804 for a free estimate, and we’ll talk through it plain.
