Our crews know Martinez streets well, from the 1920s bungalows off Alhambra Avenue to the newer developments up near Hidden Lakes. That matters because pre-1930s homes here rarely have square, stock-sized rough openings, and a door that gets forced into a mismatched frame will sag, bind, or crack the jamb within months. When you call, a live person answers and schedules your estimate around a time that works for you, with a live arrival time you can track on your phone.

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

Founded in 2001 and part of the Relay Home Co. family, Juniper Windows & Doors has spent more than two decades focused entirely on windows and doors, never general remodeling. That narrow focus is why Martinez homeowners trust us with door replacements that other contractors walk away from, like a 1920s Alhambra Valley home where the original jamb is out of square by three-quarters of an inch and the rough opening matches no stock door sold today.

Every Martinez job gets a written price before a single screw turns, covered by the 365-Day Done Right Promise. If the work isn’t right within a full year, parts and labor, we make it right. Our technicians are background-checked and uniformed, so when someone knocks on your door in downtown Martinez or up near the Franklin Canyon area, you know exactly who they are before you open it.

Sean Mackey leads our team, and he has built the operation around one standard: no estimate that morphs into a surprise invoice at the door. The Relay Visibility Guarantee gives you a live arrival time, before-and-after photos of every job, and a digital invoice you can pay from a link. Dispatch and scheduling for Martinez are coordinated from the brand’s San Francisco Bay Area office; crews serve Martinez locally every week.

Interior Door Replacement in Martinez

Interior Door Replacement in Martinez usually involves removing a worn, warped, or dated slab door and hinges, then fitting a new door to the existing jamb or installing a prehung unit when the frame is part of the problem. In a Martinez home built before 1930, the job frequently includes planing or shimming the jamb because true-dimension framing lumber means the opening is rarely a clean module like today’s stock sizes. A hollow-core six-panel slab replacement typically costs $350 – $600 in Martinez, while a solid-core or shaker-style door runs $450 – $850 depending on width, material, and hardware.

When a Slab Swap Makes Sense

If your existing jamb is square and solid, and the only issue is a scratched, dented, or builder-grade slab, we can often install a new door on the existing frame in a few hours. This is the most affordable path and works well for Martinez homes where the trim and casing are worth preserving. We check hinge alignment during the estimate so a heavier new door doesn’t sag on the old hinge mortises.

When the Jamb Needs Replacing

In older Martinez homes, a warped jamb often means the slab was never right to begin with, and a new prehung unit is the sturdier fix. We remove the old casing and frame, anchor a new prehung door to the studs, and reinstall trim cleanly. This costs more than a slab swap but eliminates binding doors and gaps that leak sound from hallways or neighboring rooms.

Interior Door Installation in Martinez

Interior Door Installation in Martinez refers to doors going into new openings, closets, or partitioned spaces, or doors replacing units where the rough frame itself needs work. In Martinez’s pre-war housing stock, this often means building out or trimming down a non-standard rough opening to fit a modern prehung door. We also install interior doors in newer Martinez homes near the Vista Oaks area, where stock sizes fit more easily. Expect installation labor to run $250 – $500 per unit, with the door unit itself adding another $150 – $700 on top depending on style and core material.

Prehung Units in Older Frames

When a Martinez bungalow’s original jamb has shifted on clay soil over 90 years, we recommend a prehung unit. The old frame comes out, the rough opening gets corrected with shims and blocking, and the new unit goes in plumb and square. This prevents the one-finger close you actually want instead of a door that needs a shoulder to latch.

Closet and Laundry Doors

Bifold and sliding interior doors in Martinez homes take daily abuse, especially in hallways near the laundry or pantry. We replace tracks, rollers, and panels, and we can switch a dated bifold to a modern barn-door or hinged setup if the opening allows. A full closet door replacement with new track and panels typically lands between $400 and $800 in Martinez.

Trusted Brands We Service in Martinez

We install and service door products from Therma-Tru, PGT, CGI, and CWS, and we keep common hardware and replacement parts on hand for Martinez customers. Therma-Tru prehung units are our go-to for older Martinez openings because their fiberglass construction holds its shape as the hillside clay expands and contracts through wet winters and dry summers. For exterior doors facing Alhambra Avenue or Highway 680 noise, we pair PGT or CGI impact-rated glass with weatherstripping upgrades so the door seals tighter and blocks more sound.

Common Door Replacement Problems We See in Martinez Homes

• Non-standard rough openings in pre-1930s homes: Downtown Martinez and Alhambra Valley houses were framed before dimensional lumber was standardized, so a stock door rarely drops in cleanly. We measure the actual opening, not the old door, and order or plane accordingly.
• Sagging hinges on clay-soil foundations: Martinez’s Diablo clay shrinks and swells with seasonal moisture, which shifts door frames over time. Reusing old hinge mortises on a heavier solid-core door causes binding within months, so we refit or replace the hardware.
• Warped slabs from coastal fog and dry inland heat: Martinez sits at a boundary where summer afternoons bake doors and foggy mornings add moisture back. Hollow-core doors from the 1970s and 80s in the Hidden Lakes and Vine Hill areas frequently warp or separate at the seams.
• Missing permits on size-changing replacements: The 2020 Martinez Municipal Code update means any door replacement that alters the opening size or header triggers a building permit. Like-for-like swaps do not, but changing a 30-inch door to a 36-inch door in a downtown home absolutely does, and skipping it can stall a sale during escrow.
