Fast, Reliable Door Replacement Across Kentfield
Replacing a door in Kentfield usually costs between $700 and $2,600 installed, depending on whether it’s an interior slab swap or an exterior door that has to meet Marin County’s fire-hardening codes. If you live off Sir Francis Drake Boulevard or up in the hills near Crown Road, you already know this isn’t a simple swap-out market. Juniper Windows & Doors handles the whole job, from measuring the jamb to pulling the permit, with a written price before anything starts. Call (682) 281-2168 to get yours.
Why Juniper Windows & Doors Is Kentfield’s Preferred Door Replacement Company
Kentfield homeowners deal with something most door contractors don’t think about: the WUI, or Wildland-Urban Interface. Marin County maps nearly all of Kentfield inside it, which means exterior door replacements here often have to meet ignition-resistant standards, not just look good. We’ve worked through those inspections. Our techs know what the county asks for on thresholds, weatherstripping, and door slab ratings, so the job doesn’t stall at final inspection.
Sean Mackey leads our team, and he’s built the operation around a simple rule: the price we write down is the price you pay. No change orders after the fact, no “we found rot” surprises. Kentfield customers get the same written estimate, digital invoice, and live arrival time whether the job is a single interior door or a full entry replacement on a hillside home.
We coordinate scheduling from our San Francisco Bay Area office, and crews serve Kentfield directly. You’ll know who’s coming, when they’ll arrive, and what the work will cost before any material gets ordered. That’s how door replacement should work.
Door Frame Repair in Kentfield
Door frame repair in Kentfield is often the real job, even when the door itself looks fine. Older homes near Ross Common or along College Avenue sit on soil that shifts with Marin’s wet winters and dry summers, and that movement pulls jambs out of square. A new slab hung in a twisted frame will bind, drag, or leave gaps that let embers and wind-driven rain through during fire season.
What We Actually Repair
We replace rotted jamb legs with rot-resistant stock, true up the frame so the door swings cleanly, and rebuild thresholds that have sagged or cracked. On exterior doors, we also check that the weatherstripping meets WUI ember-resistance specs. That’s not an upsell; it’s what the county inspector will look for.
Cost and Timing
Frame repair in Kentfield typically runs $350 to $1,100 depending on how much of the jamb has to come out. Installing a new door slab and hanging hardware usually adds $300 to $800. Most frame jobs take one day once the material arrives. Call (682) 281-2168 and we’ll give you a written range before you commit to anything.
Interior Door Replacement in Kentfield
Interior door replacement in Kentfield covers everything from swapping a hollow-core bedroom door for a solid-core panel to replacing sliding closet doors that have come off their tracks. Homes here run the range: 1950s ranchers near Kent Woodlands, later split-levels off Goodhill Road, and newer builds that still have contractor-grade slabs. Each one has different hinge spacing, jamb depths, and trim profiles.
What You Should Know Before Ordering
Measure the slab and the rough opening, not just the slab. Kentfield homes with settled foundations often have out-of-square openings, and a standard-size door may not fit without planing. We measure on-site for every job and order to the opening, not the old door’s numbers.
Realistic Pricing
A standard interior door replacement in Kentfield runs $550 to $1,400 installed, including slab, hardware, and trim adjustments. Pre-hung units cost more, $800 to $2,000, because the old jamb comes out and a new one gets set and shimmed. We’ll tell you which route makes sense for your house and hand you a fixed number before work begins.
Trusted Brands We Service in Kentfield
We install and service doors from PGT, Therma-Tru, and CGI, plus glass inserts from ES Windows. We keep common replacement components in stock for Kentfield jobs: fire-rated door slabs, WUI-compliant weatherstripping, impact-rated glass, and rot-resistant jamb stock. That means most exterior door replacements don’t wait on a special order. If your Kentfield home needs a specific brand to match existing hardware or HOA requirements, we’ll source it and lock the price before ordering.
Common Door Replacement Problems We See in Kentfield Homes
- Swollen jambs on hillside properties: Winter rain plus summer dryness causes wood to expand and contract. We see jambs that have swollen so much the door won’t latch; replacing the slab without fixing the jamb just moves the problem to the new door.
- Ignored WUI fire-hardening requirements: A homeowner replaces an exterior door without a permit, then fails the county inspection because the threshold and weatherstripping aren’t ember-resistant. We handle the permit and specs from day one so this doesn’t happen.
- Out-of-square openings in older Kentfield homes: Foundation settling means standard doors get planed to fit, but that leaves gaps. We rebuild the frame so the new door swings true and seals tight.
- Interior doors that no longer close after a remodel: New flooring raises the floor height, and suddenly the door drags. We undercut the slab cleanly or reset the hinges so the door clears the finish floor without a visible gap.

FAQs About Door Replacement in Kentfield
Yes, most exterior door replacements in Kentfield require a Marin County permit, and because Kentfield sits inside the Wildland-Urban Interface, the new door may need to meet fire-hardening specs like non-combustible thresholds and ember-resistant weatherstripping. We pull the permit and schedule the inspection for you. Call (682) 281-2168 and we’ll confirm what your specific project needs.
Because the jamb is out of square. Kentfield’s clay-heavy hillside soils expand in winter and contract in summer, which shifts door frames over time. A new slab in an old frame will still bind. The fix is frame repair, not another door. We’ll check the frame before you buy anything, and the estimate is free.
Yes. We install impact-rated glass inserts from PGT and ES Windows on exterior doors in Kentfield. These use laminated glass built to resist wind-borne debris without shattering, which matters during Marin’s high-wind fire season. We’ll confirm the glass rating meets county requirements for your zone. Call (682) 281-2168 for pricing.
We service and install doors from Therma-Tru, PGT, CGI, and ES Windows, plus CWS on custom orders. We stock common replacement parts locally for Kentfield jobs, so you’re not waiting weeks for a hinge or threshold. If your door is from another brand, we can often source parts through our supplier network.
A standard interior door takes half a day; an exterior door with frame repair and WUI compliance typically takes one to two days. Permitting can add one to two weeks depending on Marin County’s current review queue. We’ll give you a written timeline alongside your written price, so you know the calendar before you sign. Call (682) 281-2168 to get started.
