We’re Juniper Windows Pasadena, and we’ve been replacing doors across Bungalow Heaven, Hastings Ranch, Madison Heights, and the San Rafael Hills since the brand was founded in 2001. Call (626) 657-5977 for a written quote before any work starts – no estimate that morphs into a surprise invoice.
Why Juniper Windows Pasadena Is Pasadena’s Preferred Door Replacement Company
We work on Pasadena’s housing stock every week: 1900s – 1930s Craftsman bungalows, Spanish Colonial Revivals with carved wood entries, and 1950s – 60s Ranches with original aluminum sliders and hollow-core doors. That matters because a door job on a 1922 Craftsman in Bungalow Heaven is a different job than one on a 1962 Ranch off Sierra Madre Boulevard. We know the difference and we quote it accordingly.
Homeowners across Pasadena consistently mention three things in their feedback: the written price we lock before work starts, the live arrival time they get on their phone, and the fact that a real person answers our line 24/7. The 365-Day Done Right Promise covers parts and labor in writing for a full year after installation. If the work isn’t right, we make it right. Sean Mackey leads our Pasadena team, and the crew showing up at your door is background-checked and uniformed.
We also understand the permitting split that runs through this city. A door visible from the street in Bungalow Heaven may need historic design review. A replacement on an unincorporated county pocket three blocks away may need Los Angeles County sign-off. We handle both paths and we know which one applies before we quote.
Door Installers in Pasadena
Door Installers in Pasadena handle the physical replacement: pulling the old slab and frame, correcting a rough opening that has settled out of square, setting the new pre-hung unit, re-trimming, re-caulking, and hauling the old door away. When a Pasadena homeowner has a door that binds, a frame that has rotted at the bottom from sprinkler overspray, or an original hollow-core that swells after rain, this is the crew that does the work. A standard pre-hung entry replacement in Pasadena runs $1,200 to $3,200 for labor and a quality fiberglass or steel unit; a custom wood door with jamb matching on a historic property runs higher, usually $2,500 to $6,500.
Full-Frame Replacement vs. Slab-Only
Most Pasadena homes we see need a full-frame replacement, not just a new slab. Original jamb legs on 1920s Craftsman entries are often rotted at the base from decades of irrigation overspray, and the rough opening has shifted as the foundation settled. A slab swap won’t fix that. We pull the entire unit and set a new frame that is shimmed, squared, and insulated.
Seismic and Wind Considerations on Sloped Lots
Pasadena’s hillside acreage and canyon-adjacent streets see real Santa Ana wind loads, and the county requires stronger anchoring on some structures than city code does. We check the rough opening, the header, and the king studs before we quote, so we don’t discover half-rotted framing after you’ve already signed for the door.
Door Contractors in Pasadena
Door Contractors in Pasadena scope a job before a single screw turns. That means measuring the rough opening, checking the slope of the slab or threshold, verifying whether the property falls under Pasadena city design review or Los Angeles County permitting, and confirming what the wall structure actually is – stucco over wood frame, solid masonry, or a mix. A Pasadena homeowner needs a contractor when the work involves structural change, a historic property, a detached ADU, or a door that must meet current energy or seismic code. Contractor-led full replacements here run $1,800 to $4,800 for most single doors, and $2,800 to $5,500 for Ranch-era sliding glass door retrofits.
When County Permitting Applies Instead of City Review
Pasadena’s borders weave around unincorporated county pockets, particularly near Altadena and parts of Hastings Ranch. If your parcel sits in an unincorporated area, the county reviews the structural side and may pull in septic or well setback checks. We handle the paperwork and the sequencing, so the door quote you get reflects the real permit path, not a guess.
Detached ADUs, Workshops, and Outbuildings
Door replacement on a detached ADU or workshop is rarely straightforward. The original rough opening was often framed by hand, sometimes undersized for any modern pre-hung unit. The slab may slope toward the door, not away from it. We field-measure, level, and reframe where needed, then install a door that actually closes without a shoulder shove.
Trusted Brands We Service in Pasadena
We install and service doors from PGT, Therma-Tru, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, and ViewLux. For Pasadena’s dry heat and UV exposure, we lean heavily on Therma-Tru fiberglass for entry doors, PGT for impact-rated sliding glass and patio units, and CWS for custom divided-light work that holds up against Santa Ana wind. We keep common seals, weatherstripping, and hardware for these brands moving through our Pasadena schedule, which means a door replacement here doesn’t wait on a parts shipment from the East Coast. If you already have one of these product lines in your home, we can service it and match the new door to it.
Common Door Replacement Problems We See in Pasadena Homes
- Water damage to door bottoms and jambs. Pasadena’s sloped lots and decades of sprinkler overspray mean many original entry doors have rotted at the base. The door itself may be fine; the frame and sill are the failure point.
- Warped or cracked doors on detached ADUs and outbuildings. County-permitted structures from the 50s and 60s often have rough openings that don’t meet current seismic or wind-mitigation design pressure. The door flexes, cracks, or pulls its own hinges loose.
- Faded and peeling west-facing doors. Pasadena’s intense afternoon sun destroys finishes on doors that catch the western exposure. Seals break down, the door dry-rots at the edges, and the hardware loosens in the wood.
- Binding and swelling after rain. Original hollow-core doors on mid-century Ranches swell when the winter rains come, because the door was never sealed at the bottom edge and the frame allows moisture intrusion from the threshold.

FAQs About Door Replacement in Pasadena
An Altadena address is generally unincorporated Los Angeles County, so the county reviews the structural scope and may trigger septic or well setback checks on the permit. A Pasadena city address falls under Pasadena’s own planning and building department, and if the door is visible from the street in a historic district, you also face design review. We determine which path applies before we write the quote. Call (626) 657-5977 and we’ll pull the parcel record and tell you exactly what your job needs.
Yes, in most cases. Bungalow Heaven is a designated landmark district, and any door visible from the street must clear Pasadena’s design review. That typically means matching the original door style, glass texture, muntin profile, wood species or acceptable composite equivalent, and putty profile. We’ve done this work in the district, including a 1922 Craftsman where we matched the jamb profile and installed a Therma-Tru fiberglass door with a laminated glass interlayer that passed review. Call (626) 657-5977 and we’ll tell you what the reviewer will look for on your specific house.
Sometimes. Many 1960s Ranch sliders sit in an opening that is close to a modern rough opening, but the header and king studs were not designed for an impact-rated unit’s weight and design pressure. We inspect the framing before quoting. If the header is undersized, we reframe only what is needed, not the entire wall. If the opening is structurally sound, we can set a PGT or CGI impact-rated slider in a day. Call (626) 657-5977 to get a framing read on your slider.
SHGC, or solar heat gain coefficient, measures how much solar radiation passes through the glass. A lower SHGC means less heat enters. For a west-facing patio door in Pasadena’s afternoon sun, you want a SHGC of 0.25 or lower to keep the room livable without running the AC constantly. The trade-off is that very low SHGC glass can tint the view slightly. We’ll walk you through the numbers for PGT and CGI units so you choose the balance you want. Call (626) 657-5977 for an exact SHGC comparison on your wall orientation.
We field-measure everything first: the slope at the threshold, the rough opening dimensions at three points, the header size, the condition of the jamb pockets, and where water currently runs in the rain. Then we quote the door plus whatever threshold, flashing, or re-grading work is needed to keep water out. A written price covers it before we start, and the 365-Day Done Right Promise covers it after we finish. Call (626) 657-5977 to schedule a free estimate on the ADU or workshop.
