Fast, Reliable Door Replacement Across Van Nuys
A front door or patio door replacement in Van Nuys typically runs $1,400 – $4,800 installed, depending on the door style, material, and what our crew finds once the old frame comes out. Sliding patio doors run higher, usually $2,800 – $7,200, because the track, subfloor, and framing almost always need attention in a 1950s stucco home. We know Van Nuys housing stock well enough to give you a written price before work starts, and that price covers what we can see plus allowances for what we can’t. Call (831) 508-3441 for a door replacement quote that reflects your specific house, not a generic average.
Dispatching from our Los Angeles office, crews serve Van Nuys locally. Sean Mackey, who leads Juniper Windows Woodland Hills, insists on one rule: every door quote gets documented in writing before a single screw turns. No verbal ballparks that magically grow at the end.
Why Juniper Windows Woodland Hills Is Van Nuys’s Preferred Door Replacement Company
Van Nuys homeowners keep calling us for one reason: we treat a 1950s ranch house like what it is, an older home that hides surprises behind its stucco. The Door Replacement crew has opened enough walls west of Van Nuys Blvd to know exactly what lives in there: undersized headers, dry rot spreading from failed door pans, original steel casements that haven’t opened in twenty years. We budget for that reality. Then we lock the number in writing.
Our Van Nuys customers also get the Relay Visibility Guarantee on every job. You see a live arrival time before we show up. You receive before-and-after photos of the door, the framing, the flashing. You pay from a digital invoice. If something isn’t right after installation, the 365-Day Done Right Promise covers it, parts and labor, in writing, for a full year.
Every technician who arrives in Van Nuys has passed a background check and wears a Juniper uniform. When the doorbell rings, you know exactly who’s on the other side. And if you call our office at any hour, a real person answers. No voicemail tree.
Door Installers in Van Nuys
Door Installers in Van Nuys deal with a specific kind of house: 1940s to 1960s ranch and minimal traditional builds with wood-framed stucco exteriors and single-pane aluminum or wood doors that the Valley sun has been baking for sixty-plus years. A simple slab swap in a newer home might take a morning. In Van Nuys, the same job often becomes a frame repair project. A front door install typically runs $1,400 – $2,900 when the opening is sound. Add $400 – $900 when the jamb shows rot or the header needs sistering.
Exterior Door Replacement, Including Stucco Tie-In
Exterior doors in Van Nuys sit inside stucco walls, and pulling an old frame requires cutting back that stucco cleanly so the new door can be flashed and sealed correctly. We cut, install, reframe if needed, and patch the surrounding stucco so the sill doesn’t leak into the wall cavity six months later. For a standard front or side entry door, Van Nuys homeowners pay between $1,800 and $3,400 complete.
Sliding Patio Door Installation
Original aluminum sliders on Van Nuys ranches are usually warped, off-track, or leaking air through failed weatherstripping. Replacement involves removing the old frame, checking the subfloor and header, and installing a new dual-pane slider that seals against Santa Ana wind. Expect $2,800 – $7,200 installed, including haul-away of the old unit and any subfloor shimming.
Door Contractors in Van Nuys
Door Contractors in Van Nuys handle more than the door itself; they manage the permit, the framing inspection, and the stucco repair that a quality install requires. When a Van Nuys homeowner pulls a permit for an exterior door replacement, the city checks compliance with California Energy Code Title 24, which often means upgrading insulation and flashing at the rough opening once the wall is open. A door contractor who doesn’t mention this is doing you a disservice. We write that allowance into the contract from day one.
A permitted front door replacement with stucco repair and Title 24 compliance generally lands between $2,200 and $4,800 in Van Nuys. The higher end covers wider openings, custom fiberglass or steel doors, and any framing corrections the inspector requires. You’ll see every line item before we start.
Framing and Flashing Repair Before Door Install
Before a new door goes in, the rough opening has to be right: square, dry, properly flashed, and carrying the header load. In Van Nuys homes we regularly replace rotted jambs, add king studs, and install new galvanized drip caps. This work surfaces as a written change order when we open the wall, never as a verbal surprise after the fact.
Steel Casement Door Replacement
Older Van Nuys homes west of Van Nuys Blvd sometimes have original steel casement doors that have rusted solid from decades of Valley heat. These can’t be repaired, they need full frame extraction and a new rough opening retrofit. We handle the entire job, including stucco patching, and match the new door’s sightlines to the home’s original character.
Trusted Brands We Service in Van Nuys
We install and service doors from Therma-Tru, ViewLux, and PGT, three manufacturers whose products hold up to Van Nuys heat and wind better than most. Therma-Tru fiberglass entry doors give you the look of wood without the warping. ViewLux patio doors maximize glass area with narrow sightlines. PGT impact-rated products are built for wind-borne debris, and we’ve installed them on Van Nuys homes that face open exposure during Santa Ana events. We keep common parts and hardware for these brands in local inventory, which shortens lead times for Van Nuys customers. When a replacement threshold, sweep, or hinge set is needed, we rarely have to order it from out of state.
Common Door Replacement Problems We See in Van Nuys Homes
- Dry rot behind original door sills. 1950s door openings in Van Nuys usually have no sill pan or drip cap at the threshold. Water gets in at the corners, rots the subsill, and spreads into the jamb and sometimes the wall framing. We document it, write the change order, and replace the rot before hanging the new door.
- Rusted steel casement doors seized shut. The original steel out-swing doors found on some Van Nuys-era homes have been cooking in 100°F-plus summers for sixty years. They stick, they seize, and the hinges eventually tear from the frame. Repair isn’t practical; we replace the entire unit and retrofit the opening.
- Undersized headers sagging under wind load. Many Van Nuys ranch homes were framed with the minimum header the 1950s code allowed. Santa Ana winds push against a new, heavier door and expose that weakness. You feel it as a door that binds in summer and rattles in fall/winter. We sister or replace the header when we open the wall.
- Failed weatherstripping from UV and heat. Van Nuys summers bake door weatherstripping until it cracks, shrinks, and falls out of the kerf. That’s why you feel air moving around the edges and hear the door rattle. New dual-pane doors with low-E glass and fresh compression gaskets fix both comfort and cooling cost in one step.
Pricing for Door Replacement in Van Nuys, CA
A front door replacement in Van Nuys costs $1,400 – $4,800. Sliding or French patio doors run $2,800 – $7,200. The range exists because every 1950s stucco home is different once the wall is open. A clean opening with sound framing sits at the low end. Dry rot, undersized headers, Title 24 insulation upgrades, and stucco repair move the number up, and each of those items appears as a line item on a written change order before we proceed. You approve everything, in writing. Nothing happens on the fly. Call (831) 508-3441 to schedule a free estimate at your Van Nuys home.

FAQs About Door Replacement in Van Nuys
Because Van Nuys homes from the 1940s through 1960s hide conditions behind stucco that no one can see before demolition: dry rot in jambs, undersized headers, failed waterproofing, or Title 24 insulation requirements the building inspector flags once the wall is open. Your quote doesn’t “increase” arbitrarily; you receive a written change order documenting exactly what we found, what it costs, and why it’s required. You approve it before we spend a dollar. Call (831) 508-3441 and we’ll explain how allowances work before we ever touch your door.
Yes, if the opening is being modified or the door is in a location governed by Los Angeles building code, and even a like-for-like exterior door replacement can trigger a permit when the frame is disturbed. The bigger issue is that a permit in Van Nuys often means a Title 24 energy compliance check, which can require upgrading insulation or flashing at the rough opening. We pull permits for you, schedule the inspection, and build any code-required items into the written contract up front. For an exact scope for your house, call (831) 508-3441.
We can. Therma-Tru fiberglass doors come in wood-grain textures and panel profiles that echo the original mid-century look of Van Nuys ranch homes, without the warping and rot that plagued the originals. For steel casement doors, we source ViewLux or custom pre-hung units with slim sightlines that preserve the era’s horizontal emphasis. Sean Mackey’s team has matched doors on homes across Van Nuys, and we document every detail before ordering. Call (831) 508-3441 to see samples and discuss your door’s original design.
Van Nuys summers routinely exceed 100°F with intense UV exposure, and that combination bakes rubber and vinyl weatherstripping until it cracks, shrinks, and no longer seals. You’ll notice air leaking around the door edges, dust on the threshold, and higher cooling bills. We install compression-rated gaskets and door sweeps designed for high-heat climates, and we can replace failed weatherstripping on an existing door or as part of a full replacement. For a fast inspection at your Van Nuys home, call (831) 508-3441.
Yes, and the reason goes beyond the door itself. A new, properly hung door with a fresh weatherseal stops panel rattle, but loose framing and blown-out gaskets also cause the noise you hear during Santa Ana events. Our installers correct the opening, replace missing or compressed weatherstripping, and make sure the frame is anchored to the studs so wind load transfers cleanly. On a 1950s ranch near Van Nuys Blvd and Victory Blvd, our crew replaced a warped aluminum slider with a Therma-Tru door and the wind rattle disappeared, in part because we rebuilt the jamb and added proper sill flashing. Call (831) 508-3441 to talk about your specific door.
