AfterFast, Reliable Door Installation Across Los Angeles
Door installation in Los Angeles typically runs between $850 and $4,800 per opening for most residential projects, depending on whether you’re swapping a slab, installing a prehung unit, or facing the reframing and fire-rated glazing requirements common on hillside parcels. Most jobs take one to two days once measurements are confirmed and product arrives. Westlight Windows & Doors has been installing entry, storm, and sliding glass doors across Los Angeles since 2009, and our crews know what LADBS inspectors actually check on the day of final sign-off. Call (903) 354-7134 and a real person answers, day or night.
We work everywhere from Echo Park to Chatsworth, and we schedule every Los Angeles job with a committed arrival window, not a vague “sometime Tuesday.” The door you order is the door we install, at the price we wrote down before any work started.
Why Westlight Windows & Doors Is Los Angeles’s Preferred Door Installation Company
Los Angeles homeowners have seen every kind of contractor behavior there is, and a lot of them call us after someone else made a mess. Owen Satterfield, who leads Westlight, built this company on a simple idea: write the price down, show up when you said you would, and come back if the work fails. That’s the Kingswell Way, and it applies to every door we hang in Los Angeles, whether it’s a Therma-Tru entry unit in a 1930s Los Feliz bungalow or a new sliding glass door in a Sylmar ranch.
Every Los Angeles job gets the same four promises in writing before we touch the wall: a written price, a committed arrival window, a clean job site, and a written guarantee on the completed work. If a repair fails within the guarantee period, we come back and fix it at no charge. That’s the 365-Day Done Right Promise, and we hand it to you at job completion, not buried in fine print.
Our technicians are background-checked and uniformed, so when someone knocks on your door in Los Angeles, you know exactly who you’re letting in. We stock parts locally and can pull from eight manufacturer lines, including PGT, CGI, and Therma-Tru, which matters when an inspector requires a specific fire-rated unit on a VHFHSZ parcel and you need it ordered that week, not next month.
Storm Door Installation in Los Angeles
Storm Door Installation in Los Angeles protects an older front door from year-round UV exposure and keeps the occasional rain from soaking the threshold. Here, the bigger enemy is sun, not snow. A storm door on a west-facing entry in the San Fernando Valley takes brutal afternoon light for hours every day, and a cheap aluminum frame will warp within two seasons. Prices for storm door installation in Los Angeles run $650 to $1,800 installed, with custom sizing and finish upgrades pushing toward the top of that range.
What We Check Before We Hang It
The existing jamb in a 1940s Los Feliz or Silver Lake home was rarely built square, and storm doors punish any opening that’s out of plumb. We check the framing, flashing, and sill condition before ordering, because hanging a storm door on rotted sill plate just hides the problem for one more wet season.
Frames That Handle Santa Ana Winds
Periodic Santa Ana wind events can push sustained gusts hard against an exterior door face. We spec storm door frames with reinforced corners and adjust the sweep clearance so the door doesn’t chatter in a 40 mph gust up in the foothill communities.
Sliding Glass Door Installation in Los Angeles
Sliding Glass Door Installation in Los Angeles usually means replacing an original single-pane aluminum unit from a post-WWII stucco ranch or a fogged-glass slider in a coastal home losing its seal years early. Los Angeles gets roughly 284 sunny days a year, and that UV load degrades insulated glass unit seals faster than almost anywhere in the country. Expect to pay $1,200 to $4,200 for a standard two-panel slider installed, with three-panel and multi-track configurations running higher, especially on hillside properties that trigger fire-rated glazing requirements.
When the Marine Layer Attacks
In Santa Monica and Venice, persistent coastal moisture accelerates salt-air corrosion on aluminum frames and hardware. Rollers seize, tracks pit, and lock mechanisms bind within a couple of years on cheap units. We order stainless hardware as a default on coastal Los Angeles installations and mention it in your written quote so you know what you’re paying for.
Getting Title 24 and Chapter 7A in the Same Door
A sliding glass door on a Very High Fire Hazard Severity Zone parcel in Los Angeles has to satisfy both energy code and fire-rated glazing requirements. That combination doesn’t leave a contractor much room for guesswork, and we spec the unit before the sale closes, because ordering the wrong glass mid-job is how quotes jump four figures and inspections get red-tagged.
Trusted Brands We Service in Los Angeles
Westlight carries eight manufacturer lines, which means the product gets matched to your Los Angeles home rather than the other way around. For impact-rated and fire-rated requirements on hillside parcels, we install PGT and CGI units that meet Chapter 7A from the factory, not retrofitted after the fact. For entry doors that hold finish and weather seal through years of harsh western sun, we lean on Therma-Tru. For modern sliding glass systems where the homeowner wants clean lines and real thermal performance, ES Windows fills that gap. Because we stock parts locally, Los Angeles customers aren’t waiting on a slow freight line when a replacement roller or sash needs to arrive fast.
Common Door Installation Problems We See in Los Angeles Homes
- Rotted jamb assemblies under the threshold. In 1920s-1940s Spanish Colonial Revival and Craftsman-era homes across Silver Lake, Los Feliz, and Hancock Park, the original door openings hide undersized headers, rotted sill plates, and no flashing pan. A new slab hung on that framing drags within one wet season.
- Fire-rated glazing red-tags on hillside parcels. Vinyl and aluminum door frames installed on VHFHSZ properties fail inspection when the glass isn’t tempered or fire-rated. Re-ordering a Chapter 7A unit mid-job is the single most common quote-killer we see in Los Angeles.
- Stucco ranch door rack bind in the San Fernando Valley. The original single-pane slider cutouts in Valley homes were never squared for a modern prehung unit. The door binds in the track, and the marine-layer salt air corrodes hardware within a couple of years.
- Warped slabs from year-round sun exposure. A west-facing door in a neighborhood like Pacific Palisades or Sherman Oaks absorbs direct afternoon UV for thousands of hours. Untreated wood and low-grade vinyl warp, crack, and lose finish.
Pricing for Door Installation in Los Angeles, CA
Los Angeles door installation costs more than the national average because of code requirements here, not less. A standard single entry door swap runs $850 to $2,200. A prehung entry unit with new jamb, casing, and hardware runs $1,800 to $3,600. Sliding glass doors run $1,200 to $4,200. French and double doors run $2,000 to $4,800. Add $400 to $1,200 when Chapter 7A fire-rated glazing is required on a VHFHSZ parcel. Every one of those figures is a written price you receive before any work starts, not an estimate that changes at the door.

FAQs About Door Installation in Los Angeles
Yes. LADBS requires a permit for nearly all door replacements, and if your parcel sits in a designated Very High Fire Hazard Severity Zone, the inspector will specifically verify Chapter 7A compliance on any door with glazing. Swapping a solid slab without glass may not trigger the fire-rated requirement, but the permit is still required. Call (903) 354-7134 and we’ll tell you what applies to your address before you spend a dollar.
Because the original framing inside a 1920s-1940s Los Angeles door opening was rarely built to modern code. Undersized headers, rotted sill plates, no flashing pan, outdated wiring inside the wall: once these are exposed, the inspector requires them fixed. Westlight avoids the surprise by writing an inspection-first allowance into the contract, and any change gets priced and approved in writing before we touch it.
Yes. On a VHFHSZ parcel in Los Angeles, the unit must be dual-pane, tempered or fire-rated glass, with a rated frame. PGT and CGI both manufacture sliding glass doors that satisfy both code sets from the factory. We spec that unit before the sale closes so there’s no mid-job reorder and no red-tag at inspection.
It will if the hardware is cheap. Aluminum and steel hardware corrodes fast in Santa Monica, Venice, and Marina del Rey, where the marine layer sits on metal surfaces for hours. We default to stainless hardware on coastal Los Angeles installations and document it in your written quote so there’s no guesswork.
Usually, yes. The original trim on a Spanish Colonial Revival or Craftsman bungalow often can’t be sourced anymore, so we cut and fit around it rather than through it. We photograph the trim before work starts, and any trim that must be removed for flashing access gets documented in the written scope. Call (903) 354-7134 for an exact measurement and a free estimate.
