Fast, Reliable Door Replacement Across Tarzana
Door replacement in Tarzana typically runs $1,900 – $4,800 for a standard exterior door with installation, and $3,200 – $7,500 when the opening needs reframing due to the non-standard jamb sizing common in 1950s – 70s ranch homes. We’re in Tarzana weekly, and our crews know the difference between a quick slab swap and the kind of job where the stucco comes off and the framing tells a different story than the bid assumed. If your door sticks, lets heat through, or the sliding panel no longer slides, call (831) 508-3441 for a written quote before any work starts.
Why Juniper Windows Woodland Hills Is Tarzana’s Preferred Door Replacement Company
We earn Tarzana’s business one opening at a time. Homeowners south of Ventura Boulevard deal with floor-to-ceiling glass that has lost its seal, and people north of the Boulevard live with non-standard door framing that a big-box installer would never catch until the new door doesn’t fit. Our crew lead, Sean Mackey, has walked hundreds of these properties. He knows that a 1963 ranch near Reseda Boulevard won’t measure the same as a 1978 townhome near the Orange Line. Every job gets a written price before a single screw turns, and the 365-Day Done Right Promise covers parts and labor for a full year after installation. You’ll get a live arrival time, before-and-after photos, and a digital invoice you can pay from your phone. That’s the Relay Standard, and it applies to every Door Replacement job we do in Tarzana.
Door Contractors in Tarzana
Door contractors in Tarzana do more than hang a slab on hinges. On a home built between 1955 and 1975, the job is really about what’s inside the wall: undersized headers, dry rot at the jamb from failed stucco flashing, and rough openings that were never square. A licensed contractor pulls the permit, orders the right door for the opening, and schedules the inspection. We handle all of it. For Tarzana, a straightforward front door replacement runs $2,200 – $3,800. When framing repair enters the picture, expect $4,000 – $7,500. You get one number, in writing, before we start.
Rough Opening Assessment
Before we quote, we measure the actual jamb on every side. Tarzana’s original construction was rarely plumb. Our crew checks for header cracks, sill rot, and whether the rough opening is even close to square. That’s how we avoid change orders later.
Permit and Inspection Handling
We pull the permit, schedule the inspection, and stay on site until the inspector signs off. If the inspector requires a structural fix we didn’t anticipate, you get a written allowance line item before we touch it. No surprises, no job stops.
Door Frame Repair in Tarzana
Door frame repair in Tarzana is often the real project hiding behind a “simple” door replacement. The old jamb may be 1/2 inch out of square, or the king studs may have dry rot from a Santa Ana rain that found its way past bad flashing. We sister studs, reframe to true, and install the new door correctly the first time. Expect $450 – $1,200 for a jamb repair on one side, and $1,400 – $3,200 when both sides and the header need work. Every repair is priced in writing and covered by the same one-year, parts-and-labor guarantee.
Header and King Stud Replacement
Tarzana ranch homes often carry undersized headers over original patio door openings. When we open the wall and find that, the permit inspector will flag it. We bring in a structural fix, get the engineering stamp, and sister or replace the header before the new door ever goes in.
Sill and Threshold Work
Termite damage at the sill is common near planter beds and sprinkler lines. We cut out the rot, treat the exposed framing, and flash the new sill properly so water never sits against the jamb again.
Trusted Brands We Service in Tarzana
We install and service Therma-Tru, ViewLux, and PGT doors. That matters in Tarzana because our local parts stock covers hinges, sills, and sweeps for these lines, which means less waiting when a warranty repair is needed. If you have an impact-rated PGT slider that hasn’t been maintained or a Therma-Tru fiberglass entry door that’s seen twenty Valley summers, we can diagnose and repair it without ordering parts from three states away.
Common Door Replacement Problems We See in Tarzana Homes
- Non-standard rough openings north of Ventura Boulevard: Many original frames measure 80 inches tall instead of the standard 82. A door ordered to standard size won’t fit, and a second trim pass becomes unavoidable. We measure first and order to the actual opening.
- Santa Ana-driven debris on sliding doors: A wind-borne branch breaks single-pane glass on older sliders. Water then works into the jamb and rots the framing behind the stucco. We recommend large-missile impact-rated glass for south-facing and windward-facing openings.
- Seal failure on mid-century glass walls: Tarzana homes south of Ventura Boulevard often have original 1960s door systems with failed insulated glass. Heat pours through the gaps, and the cooling bill shows it. Replacement cuts solar gain dramatically.
- Dry rot behind stucco flashing: The 1970s flashing details on many Tarzana ranch homes simply failed over time. Water follows the jamb, rots the king studs, and the door starts to sag. Frame repair is mandatory before the new door goes in.
Pricing for Door Replacement in Tarzana, CA
A standard single exterior door replacement in Tarzana runs $2,200 – $3,800 with installation and basic trim. A patio slider replacement lands between $3,000 – $5,500. When framing repair, custom sizing, or impact-rated glass enters the scope, the range moves to $4,000 – $7,500. Labor in the Valley market, permit fees from the city of Los Angeles, and custom jamb work drive most of the variance. You’ll get a written quote that breaks down materials, labor, and permit costs before you commit. Call (831) 508-3441 to schedule a free, no-pressure estimate.

FAQs About Door Replacement in Tarzana
Yes, in many cases the inspector will require the header, hold-downs, and wall bracing around the new door to meet current code when the wall is opened. This is especially true for homes north of Ventura Boulevard where the original framing was often undersized. We factor this into your written quote before work begins, and any new structural requirement is priced and approved before we touch it. Call (831) 508-3441 to talk through your specific opening.
If the frame is warped, replacing just the glass won’t fix the problem. The panel won’t seat correctly, and the door will keep leaking air and water. In Tarzana’s summer heat, an aluminum frame that has lost its shape is a full replacement candidate. We can quote both options, but a warped frame means a new door is almost always the better call.
Yes, a modern door with a low solar heat gain coefficient and high-quality weatherstripping blocks significantly more heat than a 1960s single-pane slider with failed seals. Tarzana’s inland Valley temperatures reflect off hardscape and drive cooling demand hard in July and August. The replacement pays back fastest on south-facing and west-facing exposures. We can provide specific U-factor and SHGC comparisons for the door you’re considering.
We stop work at that opening, document the damage with photos, and give you a written change order for the framing repair. You approve the number before we cut anything further. Dry rot and termite sill damage are common in Tarzana homes near sprinkler lines and planter beds, so we’re rarely surprised. The repair gets pulled into your permit scope, and the inspection covers the structural fix.
In the city of Los Angeles, replacing an exterior door in Tarzana requires a permit when the opening size changes or the framing is modified. Replacing a door in the exact same opening with no structural changes may not need one, but Tarzana’s non-standard framing frequently triggers structural work that does need a permit. We pull the permit, schedule the inspection, and handle the paperwork. Call (831) 508-3441 for a straight answer about your specific door.
What Our Crews Actually Find Behind the Stucco in Tarzana
Most door replacement pages talk about hinges and hardware. This one is built around what our crews really uncover on 1960s ranch homes in Tarzana. On a 1962 ranch near Vanalden Avenue and Oxnard Street, our crew pulled a warped aluminum slider and found the original jamb was 1/2 inch out of square and the header had dry-rot from a failed 1970s stucco flashing. We sistered the king studs, reframed the opening to true, and installed a Therma-Tru impact-rated fiberglass door with laminated glass interlayer. Then our permit inspection signed off on the structural repair the same day.
That’s the difference between a door installer and a door contractor who understands Tarzana’s housing stock. North of Ventura Boulevard, ranch homes carry non-standard door framing from original construction. South of the Boulevard, mid-century modern homes with floor-to-ceiling glass battle seal failure and solar heat gain. In either case, the job is rarely a simple swap. It’s an opening, a permit, and a framing reality that needs an honest pair of eyes before any price gets locked in.
We price the job with allowances for what we expect to find, in writing. If a hidden condition changes the scope, you see the number and approve it before we proceed. When the job is done, you get before-and-after photos, a digital invoice, and a one-year parts-and-labor guarantee through the 365-Day Done Right Promise. That’s how we handle door replacement in Tarzana.
