Fast, Reliable Window Installation Across West Hills

Window installation in West Hills isn’t like window installation in Canoga Park or Woodland Hills. West Hills sits in a Very High Fire Hazard Severity Zone, and that single designation changes what windows you can legally install, what a permit review will demand, and what a reputable installer should know before they ever quote a frame. We’re TruePane Windows & Doors, and we’ve been working the hillside streets and ranch tracts of West Hills long enough to know that a bid from an out-of-area crew often falls apart at the permit counter. Call (888) 635-0804 and we’ll walk you through what your house actually needs.

Why TruePane Windows & Doors Is West Hills’s Preferred Window Installation Company

We’re not a franchise outfit that parachutes into West Hills with a truck and a clipboard. TruePane is a second-generation glazier’s company, founded by Dale Kessler, and our crews know the streets above Roscoe Boulevard, the ranch tracts off Sherman Way, and the custom homes backing up to the Santa Susana foothills. When a West Hills homeowner calls us about a fogged slider or a window that binds in July heat, we know what we’re likely to find before we pull into the driveway.

Our technicians are background-checked and uniformed. They measure every opening twice. They register both manufacturer warranty layers in writing before the truck leaves the driveway. That’s The Keystone Standard, and it’s on every job we do in West Hills. We also back the workmanship with a Done Right Promise. No paperwork fights. No fine print. If the pane is not true, the job is not done.

West Hills homeowners have called us for over a decade for single-hung retrofits, full-home slider replacements, and post-fire rebuilds. A live person answers the phone 24 hours a day, not a voicemail tree. That matters when you’ve got a broken window on a windy October night and you want to talk to someone who knows the difference between a 1960s aluminum frame and an SFM-listed assembly.

Our Window Installation Services in West Hills

Fixed & Picture Windows

Fixed windows do real work in West Hills, especially on the north-facing sides of ranch homes where the Santa Susana winds push hard against glass all winter. We install picture windows with SFM-listed dual-glazed low-E glass where permits require it, and we set them plumb and square so the seals hold through a decade of thermal cycling. A properly set picture window on a 1960s West Hills ranch should not need re-sealing because it was measured once and installed badly.

Fixed & Picture Windows

Sliding Windows

The original aluminum sliders on 1960s and 1970s West Hills homes are the single most common replacement we do. The frames warp. The rollers wear flat. The seals die young because summer highs over 100°F push the aluminum through expansion cycles it wasn’t designed to survive. We replace them with fusion-welded vinyl or thermally broken frames, sized correctly for the opening, and we flash them to keep wind-driven rain out of the wall cavity.

Sliding Windows

Casement Windows

Casement windows give West Hills homeowners something a slider can’t: a positive seal against wind. When a Santa Ana event funnels down the Pass, a properly cranked casement press-seals against its weatherstripping instead of just overlapping it. We install casements in hillside custom homes and ranch retrofits where the homeowner wants both ventilation and a tight closure. The hardware matters, and we quote manufacturer lines side by side so you see exactly what you’re buying.

Casement Windows

Awning Windows

Awning windows work well in the lower sections of West Hills homes, especially in bathrooms and kitchens where a hopper or slider lets in dust and wind. Because they hinge at the top and open outward, they shed rain even when left cracked open during a passing storm. We set awning windows with the same flashing and leveling discipline as every other Window Installation we do.

Trusted Brands We Service in West Hills

We’re an authorized installer for more than a dozen manufacturer lines, including, PGT, and CGI. For West Hills specifically, we often quote Milgard Tuscany for ranch retrofits and CGI for hillside homes where the fire-hazard classification demands a stronger frame. We also work with CWS and ES Windows when a homeowner wants a specific look or a narrow-frame profile. We keep the paperwork straight on warranty registration so you don’t have to chase a manufacturer’s phone tree later.

Common Window Installation Problems We See in West Hills Homes

  • Non-rated windows ordered before the permit. A homeowner gets a bid from an installer who doesn’t know West Hills is in a VHFHSZ. The frames arrive, the permit review flags them, and the project stalls for weeks. We check the compliance path before we order anything.
  • Seal failure from thermal expansion. The stretch of summer days above 100°F in the West Valley murders single-pane aluminum seals. A half-measure retrofit can fail within two years. We write this into the quote so there are no surprises.
  • Hillside access for oversized units. The northern streets above Roscoe Boulevard don’t always give a crew room to stage a 6-foot picture window. We scope the material haul before we commit to a day on site. If it needs a lift or a second set of hands, that’s in the estimate, not a change order.
  • Original aluminum sliders and hollow-core patio doors. These are the windows-and-doors equivalent of an open gate in a fire zone. They leak air, warp in heat, and don’t come close to current standards. We replace them with assemblies that pass a VHFHSZ review the first time.

Pricing for Window Installation in West Hills, CA

So you know the numbers before you call. A single casement window install in West Hills typically runs $850 to $1,600, depending on frame line and opening condition. A fixed picture window runs $700 to $1,400 installed. Sliding window replacements on a 1960s ranch run $900 to $1,800 per opening, and if we’re replacing an original aluminum slider with an SFM-listed assembly, expect the glazing and frame cost to push toward the higher end of that range. Full-home retrofits on a three-bedroom ranch typically land between $14,000 and $28,000. Add 10 to 20 percent for hillside access, lead-safe practices on pre-1978 paint, or oversized openings that need a custom frame. We quote line by line, on paper, and the number we quote is the number on the bill. Call (888) 635-0804 for a free estimate.

What West Hills Customers Say

Trusted by homeowners across West Hills and surrounding areas.

★★★★★

"Impact windows on the whole house. They handled the permit, the inspection, and gave me a folder with every approval number for the insurance company. My windstorm premium dropped enough to notice."

Bill T. · Verified customer
★★★★★

"Whole-house window replacement at 71 years old is not something you want to do twice. Dale walked the house himself for the quote. Crew was the same three men all four days, and the foreman knew every window by room."

Pat and Ray L. · Verified customer
★★★★★

"Eleven windows replaced in two days. The crew chief, Marcus, showed me the level on every single frame before they caulked it. My wife noticed the street noise was gone before I did."
