What makes San Marino different from Pasadena or Alhambra isn’t the weather. It’s the paperwork. The city’s building department enforces some of the strictest historic-preservation and design-review standards in the San Gabriel Valley. Exterior door replacements on the many 1920s – 1930s homes often require a Certificate of Appropriateness or design-review sign-off before a permit gets issued. That’s a step neighboring cities rarely require for a simple door swap, and skipping it is the single most expensive mistake we see homeowners make.

• Entry door replacement: $1,200 – $4,200 depending on material, sidelites, and design-review requirements
• Interior slab replacement: $450 – $1,100 per door including hardware and trim
• Pre-hung interior unit (door + frame): $700 – $1,400 per opening
• Custom jamb work on older San Marino homes: $250 – $600 per opening due to non-standard framing

Why Juniper Windows & Doors Is San Marino’s Preferred Door Replacement Company

Sean Mackey leads our team, and he’s built the company around one practice that matters most in San Marino: getting the design-review question answered before money changes hands. We don’t order a slab until we know whether the opening faces a street that triggers historic review. That single habit has saved San Marino homeowners thousands in re-order fees and stop-work delays.

We’re part of the Relay Home Co. family, founded in 2001, with two decades of installations behind the brand. Every project runs on the Relay Visibility Guarantee: a written price before anything starts, a live arrival time you can track, before-and-after photos of every job, and a digital invoice you pay from a link. No estimate that morphs into a surprise invoice at the door. And if something isn’t right after we leave, the 365-Day Done Right Promise covers parts and labor in writing for a full year.

Our technicians are background-checked and uniformed. When you book, you know who’s walking through your door on St. Albans Drive or Lorain Road. Dispatch and scheduling are coordinated from the brand’s Los Angeles office, and crews serve San Marino locally with realistic, honest lead times.

Interior Door Installation in San Marino

Interior Door Installation in San Marino usually runs $450 – $1,100 per door for a slab replacement, or $700 – $1,400 for a pre-hung unit that includes the frame, hinges, and casing. San Marino homes built in the 1920s and 1930s frequently have non-standard rough openings, so don’t assume a stock 36-inch slab from a big-box store will drop in cleanly. We measure every opening before ordering anything, and most of our San Marino interior work includes custom jamb extensions because the plaster returns are thicker than modern drywall.

Homeowners along Huntington Drive and in the neighborhoods near Lacy Park often call us when a dated hollow-core door has warped, a bathroom door no longer latches, or an original five-panel door needs to match replacements in adjacent rooms. We replace the slab, adjust or replace the jamb, set the hinges, and install new hardware. If the floor has settled and the door rubs, we address the reveal before hanging anything.

Matching Original Details

Older San Marino homes often have original door casings with profiles you won’t find at a supply yard. We source matching trim or mill a close profile locally. When a client asks us to match an existing door style, we document the panel configuration, stile width, and hardware finish before quoting, so the new door reads as part of the house rather than a patch.

Hardware and Swing Corrections

Some San Marino interiors have doors that swing the wrong way into tight hallways. We re-hang slabs, mortise for new hinges, and patch old hardware locations. This is common in homes where a previous owner flipped a door without thinking through traffic flow, especially in the smaller bedroom hallways of 1930s-era residences.

Door Installers in San Marino

Door Installers in San Marino have to handle more than square openings and level floors. The city’s older housing stock frequently includes out-of-square headers, thick plaster returns, and rough framing that was hand-cut before standardized dimensions existed. Our crews shim, plane, and build out jambs on nearly every pre-1940 home we touch. For flat-lot homes near Valentine Elementary or the newer builds around the Huntington Library corridor, the work is more standard, but we still measure twice before ordering anything.

A typical exterior door installation in San Marino takes one day once the slab arrives. Interior doors go faster: we can usually hang two or three slabs in a single day, depending on how much jamb work each opening needs. Custom orders through Therma-Tru, ViewLux, or PGT take two to six weeks from order to arrival. If design review is required, add one to three weeks before the order is even placed.

Front Door Replacement with Design Review

We recently replaced a weather-beaten original front door on a 1928 Spanish Colonial in the Huntington Library-adjacent Lacy Estates area, matching the arched jamb profile and sourcing a Therma-Tru fiberglass slab with a factory-applied stain that mimicked the original mahogany. Because the opening faced the street, we pulled the design-review paperwork before ordering, and the homeowner avoided a stop-work notice that a neighboring contractor had received the month prior on a similar Tudor two blocks over.

Hillside Adjustments and Thresholds

San Marino’s hillside lots on streets like St. Albans Drive and Oak Grove Avenue often have grade changes and stucco-to-wood transitions that force threshold modifications and flashing details not typical on flat-lot replacements. We check the exterior grade against the interior floor height before the door is fabricated. Getting that wrong means water under the threshold or a door that drags on the landing every time it opens.

Trusted Brands We Service in San Marino

We’re direct with eight product lines, and for San Marino homes we most often recommend Therma-Tru fiberglass for front doors that need to look like wood without the maintenance, ViewLux for contemporary homes that want clean sightlines and strong thermal performance, and PGT when a hillside home on the north edge of the city needs impact-rated glass. We keep installation hardware and common jamb components on our trucks so San Marino jobs don’t stall waiting for a hinge or a threshold from a distributor. If a door slab arrives with a finish issue, we handle the warranty claim directly with the manufacturer.

What we don’t do is sell you a brand because it’s what we have in stock. We spec the product for the opening, the solar exposure, and the style of the house. A shaded entry on a Mediterranean Revival needs a different threshold design than a west-facing door near the San Marino Country Club.

Common Door Replacement Problems We See in San Marino Homes

• Historic-preservation surprises: A homeowner orders a stock exterior door, then discovers the design-review committee requires a specific panel configuration and jamb return profile. That’s a re-order and three more weeks of lead time. We check what the city’s overlay triggers before we quote anything.
• Non-standard rough openings: San Marino’s 1920s homes frequently have rough framing that was hand-cut. A standard 36-inch slab won’t always fit without custom jamb extensions, planing, and shimming. We measure both width and diagonal on every opening.
• Hillside threshold problems: On streets like St. Albans Drive and Oak Grove Avenue, grade changes force threshold modifications. Stock thresholds leak when the exterior landing slopes toward the door, and a correct flashing detail is the difference between a door that lasts and one that rots the subfloor.
• Warped slabs from sun exposure: West-facing doors in San Marino take intense afternoon heat. Older solid-wood doors warp, crack, and stop latching. We often recommend fiberglass slabs with factory-applied stains that hold their shape and finish far longer in direct sun.
