Fast, Reliable Door Replacement Across Marina del Rey
Door replacement in Marina del Rey usually costs $850 – $4,200 for a typical entry door, including labor and materials, with most standard installations running $1,200 – $2,600. The work typically takes one day once the door arrives, but ordering custom sizes for this area’s many non-standard condo and canal-front openings can add 2 – 4 weeks. Juniper Windows & Doors is the Door Replacement team serving Marina del Rey, and we’re the ones measuring, ordering, and installing right the first time. Call (682) 281-2168 for a written estimate before you commit to anything.
Why Juniper Windows & Doors Is Marina del Rey’s Preferred Door Replacement Company
Marina del Rey door openings rarely match the manufacturer’s catalog. Our crews work along Via Marina, Admiralty Way, and the beachside pocket around Basin D every week, and the pattern holds: mid-century condo buildings, canal-front townhomes, and older stucco complexes where wall thickness, jamb depth, and swing clearance all drift from stock dimensions. We field-measure every slab before ordering. That means no door arriving at the curb with a surprise gap at the sill, no improvised shim stacks, and no change order once work starts.
Sean Mackey leads our Marina del Rey installations. He keeps our team focused on one standard: written pricing first, then the 365-Day Done Right Promise in writing once the job is complete. If a hinge binds, a threshold leaks, or the door binds against the frame at any point in that first year, we return and fix it. Parts and labor, covered.
We answer the phone live, 24/7. A real person picks up, takes your address, and schedules a measured estimate at a time that works for your building’s access rules. We coordinate with front-desk staff, freight elevators, and HOA design review panels because door replacement in a coastal Marina del Rey condominium works differently than a house with a driveway.
Interior Door Installation in Marina del Rey
Interior Door Installation in Marina del Rey comes down to one thing more than any other: wall thickness. Many of the mid-century condo buildings here sit on former tidal marsh, and their interior walls were built differently than a typical Los Angeles tract house. A stock interior door jamb assumes a 4⅝-inch wall. Marina del Rey units regularly measure 5½ to 6½ inches at the bedroom and bathroom openings, particularly in older stucco buildings on concrete block. That means we order a custom jamb width, or we build out the frame cleanly so the casing sits flush against the drywall without gaps or trim gaps.
Here’s what the job involves. We pull the old slab, inspect the rough opening for squareness, measure the wall depth at three points, and then order from PGT, Therma-Tru, or ViewLux depending on the door style you want. Installation usually takes a few hours per door. A standard hollow-core interior door in Marina del Rey runs $300 – $650 installed. Solid-core doors, which block sound much better in shared condo walls, run $500 – $950. Custom dimensions, which are common here, add $150 – $400 per door.
Bypass and Pocket Doors for Marina del Rey Condos
Sliding bypass doors are common wardrobe solutions in older Marina del Rey units, and the track hardware degrades faster with salt air. If a client wants to switch from a swinging door to a pocket door in a 34-inch opening, we check the wall cavity for plumbing and electrical first, because many of these buildings hide stacks in unexpected places.
Sound Reduction on Shared Bedroom Walls
On Via Marina and Admiralty Way, unit-to-unit noise is a real complaint. A solid-core interior door with a proper perimeter seal reduces sound transmission noticeably versus the original hollow-core door. It is not recording-studio isolation, but it makes a measurable difference in a hallway-facing bedroom.
Door Installers in Marina del Rey
Door Installers in Marina del Rey see one problem more than any other market in Los Angeles County: the door opening is not square and not standard. That is why our installers template every slab before ordering, and why we keep a note on each building’s typical rough opening in our job files. Concrete-block party walls and wood framing that has moved over decades of soil settlement means the hinge spacing, reveal lines, and threshold height all need to be measured against the actual frame, not the catalog drawing.
Installation for a standard prehung exterior door in Marina del Rey runs $500 – $1,100 in labor, with materials adding whatever slab and hardware you select. A full replacement including a rot-resistant jamb, threshold flashing, and weatherstripping typically lands between $1,700 and $3,800 for a quality Therma-Tru or ViewLux entry door. If the rough opening needs reframing, which happens more often in concrete-block buildings, add $400 – $900 to the cost.
Jamb Reconstruction in Marine Air
Untreated wood jambs do not survive long near the main channel. Morning marine layer, salt spray, and direct sun from the west combine to rot the bottom 12 inches of most exterior door frames within a decade. We rebuild jambs in rot-resistant material and wrap the exposed faces so the problem does not return the next spring.
Threshold and Weatherseal Replacement
The onshore breeze pushes water against the door threshold at an angle. A properly sloped, sealed threshold with a double-fin sweep keeps that moisture outside. This is detail work, and it is where cheap installations fail first.
Trusted Brands We Service in Marina del Rey
We stock and install Therma-Tru, PGT, and ViewLux doors for Marina del Rey customers. Therma-Tru entry systems hold up well against salt air and will not warp like the original wood slabs. PGT makes impact-rated door glazing that meets coastal code requirements for wind-borne debris with minimal frame bulk. ViewLux offers contemporary aluminum door systems with narrow sightlines that suit the mid-century condo aesthetic common along the peninsula. Because we install these brands regularly in Marina del Rey, we can order replacement glass, hinges, and sweeps without waiting on out-of-state freight for most models.
Common Door Replacement Problems We See in Marina del Rey Homes
- Jamb rot from marine moisture. Salt-laden air and morning condensation off the main channel eat untreated wood jambs and door bottoms much faster than inland neighborhoods. A replacement that skips rot-resistant jamb material or proper flashing will be soft and swollen again within a few seasons.
- Non-standard opening widths. Many Marina del Rey condos and canal-front townhomes have wall thicknesses and block frames that do not match a stock 32-inch or 36-inch prehung door. Ordering without field measuring leads to a costly reframe or a gap that lets the marine breeze whistle through.
- Freight and access delays. Coastal high-rises and gated canal communities here restrict delivery windows and require certificates of insurance for freight trucks. A door that arrives on a standard commercial delivery can sit at the curb for a week while access paperwork gets sorted, and that pushes the installation date back with it.
- HOA and coastal design review. Many Marina del Rey associations mandate specific door styles, paint colors, and hardware finishes. An installer who hasn’t pulled the architectural review approval before ordering can end up with a door that fits the opening but violates the building’s approved palette, and you eat the restocking fee.
On a canal-front townhome off Via Marina, our tech replaced a warped Therma-Tru entry door and its rotted wood jamb that had been slowly damaged by marine air and salt spray off the main channel. Because the opening was a non-standard 34-inch width with a shallow header, we templated the slab, rebuilt the jamb in rot-resistant material, and set a Low-E insulated glass unit to cut the afternoon heat gain through the door glass. We also added a laminated glass interlayer for extra safety on the glazed insert, then re-flashed the threshold and finished with new weatherstripping so the door sealed tight against the onshore breeze.
Pricing for Door Replacement in Marina del Rey, CA
A standard entry door replacement in Marina del Rey runs $1,200 – $2,600 for a prehung Therma-Tru or ViewLux unit with basic hardware and a rot-resistant jamb. A custom or non-standard opening, common in the condo stock around Admiralty Way and Basin D, runs $2,800 – $4,200. Interior doors land lower: $300 – $650 installed for hollow-core, $500 – $950 for solid-core. Impact-rated patio doors with PGT laminated glazing start around $3,800 and climb from there depending on glass package and frame color.
What moves the price: the opening dimensions, whether the jamb needs rebuilding, whether your building requires a specific finish, and what glass package makes sense for your exposure.

FAQs About Door Replacement in Marina del Rey
A like-for-like entry door swap with no structural changes typically does not require a building permit in Marina del Rey, but if the rough opening is enlarged, the header is touched, or the door is part of a fire-rated assembly in a condo corridor, the LA County building code does require a permit. Your HOA’s design review runs separately from the county. We pull the county permit when the scope calls for it, and we handle the HOA submission packet so your approval is in hand before the door is ordered. Call (682) 281-2168 to discuss your building’s specific situation, and we will tell you exactly what is needed.
Replacing a standard patio slider with PGT impact-rated glazing can qualify you for a premium discount with most insurers that write coastal policies in Marina del Rey. The insurance carrier needs documentation of the product’s Miami-Dade or LA County coastal approval, which we provide with the installation packet. The discount varies by carrier, but many homeowners recover a meaningful part of the upgrade cost over the life of the policy. Call (682) 281-2168 and we will walk you through what to send your agent.
Marine air accelerates rust on steel hinges and hardware and causes untreated wood jambs and slabs to swell, warp, and rot within a few years. For Marina del Rey, we specify stainless or coated hardware, rot-resistant jamb material, and fiberglass or composite door slabs from Therma-Tru or ViewLux rather than solid wood. An impact-rated glazed insert is worth considering on west-facing doors because the afternoon sun through the glass is a major heat load in summer. Call (682) 281-2168 for a material recommendation specific to your building and exposure.
Yes. We template the exact opening dimensions, including wall depth and reveal width, before ordering any slab or prehung unit. Marina del Rey condos regularly run 33, 34, or 35 inches on original entry doors, and many jambs sit tighter than 4⅝ inches. We order the correct width, and where the jamb depth is off, we build the frame out or plane it down cleanly. The written price you approve already includes whatever the opening requires. Call (682) 281-2168 to schedule a measured estimate.
Plan on one week for field measurement and HOA review, two to four weeks for custom or non-standard doors to arrive, and one full day for installation including weatherseal and threshold work. A standard prehung unit can arrive in as little as one week if it is in our local stock. Final inspection, when a permit applies, happens within a few days of install. We give you the calendar before you sign anything, and the written price does not move after that.
If you have a door in Marina del Rey that sticks, leaks, or just doesn’t seal the way it should, call (682) 281-2168. We will measure the opening, give you a written price, and install a door that handles the marine air without complaint. Estimates are free, and the number is the number.
