Fast, Reliable Door Installation Across Los Angeles
Door installation in Los Angeles typically runs $900 to $4,200 for an exterior entry door, and $1,800 to $6,500 for a sliding glass door, with most projects completed in one to two days once materials arrive. If you live in an older stucco or wood-frame home in Los Angeles, plan for possible framing or seismic anchoring upgrades that code may require. We’re Owen Satterfield’s crew at Westlight Windows Los Angeles, and we’ve been doing this since 2009. Call (213) 810-3461 for a free estimate and a written price before any work starts.
Why Westlight Windows Los Angeles Is Los Angeles’s Preferred Door Installation Company
We’re an independently owned and operated Kingswell location, which means we answer to our customers in Los Angeles, not a distant corporate office. Owen Satterfield built this company on a simple promise: a written price before any work starts, a real arrival window, a clean job site, and a written guarantee on every single job. That’s the Kingswell Guarantee, and it applies to every door we install from Echo Park to Westchester.
Our technicians are background-checked and uniformed, so when someone knocks on your door to install a new one, you know exactly who you’re letting in. We carry eight manufacturer lines including PGT, CGI, CWS, and Therma-Tru, which means we match the door to your Los Angeles home instead of forcing whatever’s in stock. And if the work isn’t right within the guarantee period, the 365-Day Done Right Promise means we come back and fix it at no charge. No negotiation. No fine print.
Storm Door Installation in Los Angeles
Storm door installation in Los Angeles streets like Larchmont Boulevard and homes through the San Fernando Valley runs $400 to $1,100 for a standard unit, including installation. A storm door is the outer door mounted in front of your main entry, and in Los Angeles it serves a double purpose: it gives you a screen for the sea breeze in Playa del Rey and an extra layer of security when the Santa Ana winds rattle everything.
Why a Storm Door Makes Sense in LA
Most Los Angeles homes built before 1980 let the outside air find its way in around the original door. A properly installed storm door with weatherstripping cuts that draft and lowers your cooling load in August when the inland valleys bake. We set them on reinforced jambs and make sure the closer holds against wind gusts off the canyons in Los Angeles.
The Therma-Tru Fit
Therma-Tru storm doors are one of our flagship lines because they hold up to direct sun without warping. That matters in Los Angeles, where a west-facing entry takes UV exposure from 1 pm until sunset nearly year-round. We measure, order, and install, and you get the written price before we touch a single screw.
Sliding Glass Door Installation in Los Angeles
Sliding glass door installation in Los Angeles runs $1,800 to $6,500 depending on glass package, frame material, and whether the rough opening needs correction. On 1950s steel casement homes in Mount Washington and other hillside neighborhoods, the original sliding doors often sit in openings that have drifted out of square over decades, so stock units skip right past the problem. We custom-flash and shim those openings the right way.
Impact-rated Glass for Wind and Fire Zones
If your Los Angeles home backs up to a canyon or sits in a wind-blasted corridor near the 405, we often recommend PGT or CGI impact-rated sliding doors. These aren’t just about hurricanes, they’re about what gets airborne when Santa Ana winds hit 60 mph through the passes. And if a permit gets pulled on an older Los Angeles home, the inspector may flag the existing glass for safety compliance. Replacing the door with a compliant unit solves that in the same trip.
When the Rough Opening Isn’t Right
We replaced a sliding glass door on a Mount Washington hillside house with rusted-shut 1950s steel casement windows. The rough opening was 2 inches out of square, so our crew custom-flashed the stucco return and anchored the new jamb through the post-and-beam framing with seismic clips. No unpermitted shortcuts, because the open wall triggered a framing upgrade per LA code. That’s the difference between a door that lasts 15 years and one that starts sticking in two.
Trusted Brands We Service in Los Angeles
We install PGT and CGI impact-rated door systems, CWS entry and patio doors, and Therma-Tru entry and storm doors for Los Angeles homes. Because we’re a Kingswell location with local stock, parts and service calls don’t wait on a shipment from across the country. If a door we installed in South Pasadena or West Hollywood needs a hinge, a latch, or a seal, you get it without a four-week backorder. We pick the brand based on what your house actually needs: exposure, framing type, glass code, and budget.
Common Door Installation Problems We See in Los Angeles Homes
- Rotted frames hidden behind stucco. Water finds its way behind the stucco weep screed over decades, and by the time the door sticks, the jack studs and sill have rotted. The stucco hides it until removal reveals failed waterproofing and a frame repair that wasn’t in the original scope. We price these repairs honestly when we find them, with a written change order approved before we proceed.
- Non-tempered glass in old sliding doors. Pre-1980 Los Angeles homes often have sliding doors with standard annealed glass that shatters into deadly shards. When a permit gets pulled, code often requires safety glazing on that door. Replacing the whole unit with a code-compliant door beats retrofitting film onto 60-year-old frames.
- Corroded or missing seismic anchors. In many soft-story Los Angeles structures, sill anchor bolts from the 1950s are gone or rusted through. Installing a modern door without upgrading the sill anchor will fail a structural inspection and void the permit. We pull the base plate and inspect before we hang anything.
- Doors that bind after the first rain. Swelling frames and stucco movement from the freeze-thaw cycle in the hills around Griffith Park can shift a door jamb by a quarter inch. That’s enough to make a deadbolt grind. We flash and seal around the perimeter so water stays out of the wall cavity and the frame stays put.

FAQs About Door Installation in Los Angeles
Replacing an exterior door itself does not automatically trigger a full seismic retrofit, but on many pre-1980 wood-frame and stucco homes in Los Angeles, opening the wall exposes missing or corroded sill anchor bolts that the building inspector will require you to replace before the permit is signed off. That’s a code compliance repair, not an optional upgrade. Call (213) 810-3461 and we’ll walk you through what’s likely to be flagged on your specific home before you spend a dollar.
Hillside homes in Los Angeles neighborhoods like Mount Washington, Silver Lake, and Echo Park often have rough openings that have drifted out of square or were never standard to begin with, since many were built post-and-beam with no foundation movement tolerance. Stock doors need square openings. Custom fabrication or extensive shimming and flashing is the only way to get a clean, sealed fit. We measure and order the right unit, and you get the written price before we cut anything.
Impact-rated glazing is not required on every Los Angeles door replacement, but it is required on any door where the glazing falls within a certain distance of a walking surface or where a permit inspection flags existing non-tempered glass. In wind-prone canyons, it’s also the practical choice because Santa Ana winds launch debris at 60 mph. We quote both standard and impact-rated options and let you decide. Call (213) 810-3461 for a quote on both.
The biggest hidden cost is frame rot: decades of water intrusion behind the stucco weep screed rots the jack studs and sill plate, and that has to be repaired before a new door can be set. The second is seismic anchors, which are often missing or corroded on pre-1980 Los Angeles homes. The third is glass compliance: the inspector may require safety or impact glazing on the new unit. We write allowances into our contract for exactly these conditions, so the price you see at the walkthrough is the price you pay, with any changes approved in writing before we proceed.
Yes, in most cases a Therma-Tru storm door can be mounted to the existing door frame of a 1950s stucco home in Los Angeles without tearing out the original frame, as long as the jamb is still structurally sound and square enough to hold the mounting screws. We install into the existing casing with proper shims and seal the perimeter. Call (213) 810-3461 for a free assessment.
