Why Juniper Windows Pasadena Is Altadena’s Preferred Door Replacement Company
Altadena homeowners call us because we show up knowing what a 1923 Craftsman jamb looks like versus a 1960s ranch rough opening. The difference matters: most door replacement crews work from stock sizes that fight old framing. We field-measure every opening and write the price down before ordering anything. That written number does not move, backed by our 365-Day Done Right Promise, which covers parts and labor on the completed install for a full year.
Our technicians are background-checked and uniformed, and The Relay Standard means you get a live arrival time you can track, before-and-after photos of the door, and a digital invoice you can pay from your phone. Altadena customers get the same transparency they expect from a rideshare app. If something isn’t right after install, we return for a free second visit, no charge, no argument.
And because a real person answers our phone 24/7, you never sit in a voicemail queue when a door won’t latch at 7 p.m. on a Sunday.
Door Contractors in Altadena
Door Contractors in Altadena handle the full replacement: removing the old slab and hardware, assessing the jamb and rough opening, and installing a new door that actually fits the framing it sits in. On a 1910s Craftsman near Lake Avenue, that often means custom-trimming a premium slab to match original 2.25-inch thick jambs rather than forcing a modern pre-hung unit into an opening that hasn’t been square since the Coolidge administration.
For a standard single exterior door replacement in Altadena, expect $1,200 to $4,800 installed, depending on material and glass package. A custom door with millwork matching runs $3,500 to $9,500. The bigger cost driver on a home this age is usually the jamb work, shimming, and trim profile matching, not the slab itself.
Custom Millwork and Period Matching
Homes in the Presidents Streets neighborhood have original Douglas fir detailing that deserves more than a box-store slab. We cut and route trim to match the existing profile, and we can source glass packs that preserve the wavy-glass look in side lites. You keep the character. The door actually closes square.
Designer and Architect Coordination
When an Altadena homeowner is working with a designer on a full entry remodel, we coordinate directly: door slab, hardware finish, glass specification, and jamb build all get locked into the written estimate before ordering. The longest lead item in the whole project is almost always the custom door or specialty glass, so we order that first and schedule the balance around it.
Door Frame Repair in Altadena
Door Frame Repair in Altadena typically costs $450 to $1,800, depending on how much of the bottom of the jamb has rotted out and whether the frame needs partial or full replacement. On wood-frame homes built between 1910 and 1950, sprinkler overspray against the entry wall is the usual culprit: the bottom 12 inches of the jamb wicks water for years, dry rot sets in, and one day the door binds in the frame for no obvious reason.
The fix is not hanging a new slab on a compromised frame. We cut out the rotted section, splice in new wood or composite filler matched to the original thickness, and re-hang the door with fresh shims. If the frame is too far gone, we rebuild the jamb to original dimensions rather than tearing out surrounding masonry or siding.
Jamb-Sag Repair on Settled Openings
Altadena homes on hillside lots settle over decades. A door that swung freely in 1985 might bind at the top corner today. We re-shim and re-hang rather than plane the slab down, which preserves the original door and the millwork profile around it.
Weatherstripping and Threshold Replacement
Intense sun and Santa Ana winds chew through weatherstripping faster in Altadena than on the coast. If you feel daylight under the door or dust blowing through in October, the threshold and seals likely need replacement. This runs $250 to $650 and meaningfully cuts drafts in winter.
Trusted Brands We Service in Altadena
We install and service PGT, CGI, CWS, and ViewLux doors, plus Therma-Tru for classic wood-grain entries. For Altadena hillside homes with brush-fire exposure, CGI and PGT impact-rated doors are common requests because they’re built to resist wind-borne debris while meeting fire-safe glazing standards. We keep local stock of common hardware, thresholds, and weatherstripping for these lines, which means replacement parts for a failed seal or sagging hinge don’t sit in a warehouse queue for two weeks.
Common Door Replacement Problems We See in Altadena Homes
- Warped and settled original doors. A century of dry heat and hillside settling leaves solid wood doors that no longer sit square in the frame. The door binds at the top, drags at the bottom, and the deadbolt stops aligning with the strike plate.
- Dry rot in the bottom of the jamb. Sprinkler overspray against wood-frame walls is a slow killer in Altadena. By the time the door starts sagging, the bottom foot of the jamb is often powder.
- Failed weatherstripping from sun and wind. The San Gabriel foothill sun bakes rubber seals until they crack, and Santa Ana winds push dust straight through the gaps. This is a seasonal annoyance that turns into a heating and cooling bill if ignored.
- Stock pre-hung doors forced into old openings. We see this constantly: a previous contractor ordered a standard 80-inch pre-hung unit for a 1915 Craftsman with an opening that’s 79 and 5/8 on one side and 80 and 3/8 on the other. The fix is custom-fitting, not shimming harder.
Pricing for Door Replacement in Altadena, CA

FAQs About Door Replacement in Altadena
Because a big-box stock slab is 80 inches tall and your 1920s Craftsman jamb is not. Custom doors are built to the exact dimensions of your existing opening, with the glass pack, stile width, and panel profile you specify. The shop order itself takes 4 to 6 weeks, then finishing and delivery add another 1 to 2. A stock slab off the floor of a retail store still has to be cut to fit your jamb, which often destroys the original millwork profile and looks wrong from the moment it’s hung. We order the custom door first because it’s the critical path on the schedule, and we give you the written price before we place that order. Call (626) 657-5977 and we’ll map the timeline for your specific opening.
Yes, and it’s the right call on about half the Craftsman homes we walk into in Altadena. If the jamb is square, the sills are sound, and the rot hasn’t eaten the bottom corners, we remove the old slab, prep the hinges, and hang a new door trimmed to match the original thickness. You keep the original frame, the trim, and the character. The slab itself runs $800 to $2,400 depending on material, and installation with hardware and weatherstripping is typically $500 to $1,200. We’ll tell you honestly if the frame is too far gone to save, and that assessment is part of the free estimate. Call (626) 657-5977 to schedule a look.
Request a 20-minute fire-rated door assembly as your floor, and on steeper lots with direct wildland interface we often specify a 45-minute rated unit. The key spec is not just the label on the slab but the full assembly: frame, hinges, glazing, and the seal. For glass in or beside the door, you want fire-rated or impact-rated glazing that holds up to heat and debris without shattering, and the edge seals should be intumescent, meaning they expand when heated to block smoke. We spec these units through PGT and CGI, both of which build for California hillside conditions. Get the exact spec for your lot by calling (626) 657-5977; we’ll pull the current Los Angeles County requirements for your address.
The door isn’t swelling; the frame is moving. Santa Ana winds bring dry air and big barometric swings, and on an older wood-frame Altadena home the jamb shifts just enough to pinch the slab. The fix is re-hanging the slab with new shims and, in many cases, trimming 1/8 to 3/16 inch off the latch side to give the door room to move without binding. We then re-weatherstrip the opening so you don’t trade the binding problem for a draft problem. This repair runs $300 to $700. Call (626) 657-5977 for an exact quote; it’s a same-visit fix in most cases.
For a same-size door replacement, usually not. Los Angeles County, which governs Altadena, treats like-for-like replacement of an exterior door as maintenance when you are not changing the rough opening or the wall structure. If you are enlarging the opening, changing the header, or adding a side lite where one didn’t exist, a permit is required and we pull it for you. Where the line gets blurry is on hillside properties with fire code overlays; changing door glazing or achieving a new fire rating can trigger a plan check. We sort that out in the estimate phase so the job doesn’t stall at inspection. Call (626) 657-5977 and we’ll check your specific property against current County requirements.
