AfterFast, Reliable Door Installation Across Kentfield
Door installation in Kentfield runs $1,200 to $7,500 for most entry, French, and custom door projects, with design-review-sensitive custom work on Craftsman and Tudor homes reaching $9,000 to $14,000 when fire-rated jambs and period-matched millwork are required. TruePane Windows & Doors serves the 94914 corridor daily, from the flat courts off Sir Francis Drake to the upslope lanes above College of Marin. Crews know that a door on a shaded north elevation off Woodland Road behaves differently than one on a sunny west-facing lot near Crown Road. Call (888) 635-0804 and a live person answers, any hour, to schedule a door installation estimate in Kentfield.
Why TruePane Windows & Doors Is Kentfield’s Preferred Door Installation Company
We have hung doors in Kentfield long enough to know what the county planner will flag before we ever cut a hinge mortise. This is unincorporated Marin County. That means design review applies to visible elevations, and a door that looks fine on a showroom floor can stall at the permit counter because the profile does not match the original lite pattern. We quote for that reality up front, not after the bill is written.
Every Kentfield job runs on the same rule Dale Kessler wrote on the shop whiteboard: if the pane is not true, the job is not done. Our technicians measure every opening twice, wear uniforms, and register both manufacturer warranty layers in writing before the truck leaves your driveway. That is the Keystone Standard, and it is on every TruePane contract.
The Done Right Promise covers the workmanship. If something is not right, we come back and make it right. No paperwork fights. No arguing about what the warranty says. We stand behind it.
Call (888) 635-0804. A background-checked Kentfield-area technician will walk the opening with you, check the rough framing and sill condition, and give you a written line-item quote that reflects what Kentfield’s design review and fire-zone rules will actually require.
Our Door Installation Services in Kentfield
Most Kentfield homeowners need a door that solves two problems at once: standing up to the Ross Valley’s wet-dry cycling and passing Marin County’s design review. We stock and install for both.
Entry & Swing Doors
Entry door replacement is the bread and butter of Kentfield work. The original wood doors on 1920s and 1930s homes have often taken decades of morning condensation off the redwood canopy, and rot at the bottom rail is common. We install pre-hung steel, fiberglass, and wood-clad entry systems, but we always check the sill pan and rough opening first. In Kentfield, the door itself is rarely the only thing that needs work.
Double & French Doors
French doors on Kentfield hillside lots fail in a specific way: unretained fill settles under the slab on the downhill side, the jamb goes out of square, and the out-swing panel starts dragging. We see it on the sloped lots below Corte Madera Ridge and above the Ross Valley floor. Shimming a hinge buys a month. We reset the threshold, re-square the jamb, and re-flash the pan so the door swings true for years.
Bifold & Folding Doors
Bifold and multi-panel folding doors are showing up on more Kentfield remodels, especially mid-century ranch homes where the original patio door was a single-width slider. These units carry substantial glass weight, and on a 1960s floor assembly the header often needs reinforcing before the door can be hung. We scope that in the quote. Door Installation of this type in Kentfield requires structural awareness that generic installers skip.
Pivot Doors
Pivot doors make a dramatic entry, but on Kentfield estates with heavy tree cover and shaded north faces, the door slab has to be engineered for dimensional stability or it will warp within two seasons. We work with Marvin, PGT, and CGI to specify pivot systems rated for the exposure. The door has to swing on the hinge line, not twist against the jamb. That is the whole job.
Arched & Custom Doors
Kentfield’s unincorporated Marin County design review often requires historically sympathetic door profiles and hardware for visible elevations. Swapping in an off-the-shelf fiberglass door can trigger permit revisions, while a custom wood-clad door with period muntin patterns sails through. We draw, order, and install arched and custom doors that match the house, not just fit the rough opening.

Trusted Brands We Service in Kentfield
TruePane is an authorized installer for more than a dozen manufacturer lines, and for Kentfield doors we regularly quote, PGT, and CGI side by side on paper so you can see the cost difference and the fire-rating difference before you buy. Marvin’s wood-clad units are the go-to for period-sensitive Kentfield work. PGT and CGI bring the impact and fire-rated assemblies that Marin County increasingly requires on upslope lots. We do not push one brand. We pull the numbers and talk it through.
Common Door Installation Problems We See in Kentfield Homes
- Rot migrating from the threshold into the king studs. On the wooded upslope streets near the Rose Bowl, redwood duff and leaf litter pack against the sill pan and hold moisture for months. You will not see the damage from inside until the door starts pulling away from the jamb.
- Sagging out-swing French doors on hillside lots. Fill settles, the slab drops a quarter inch on the downhill side, and suddenly the inactive panel will not latch. We see it regularly on the slope-side homes above Sir Francis Drake.
- Warped wood entry doors on shaded north and east elevations. A door that never gets direct sun through the redwood canopy never fully dries. Paint fails, the slab cups, and the door starts sticking against the jamb in winter.
- Design-review rejections on replacement doors. Homeowners buy a door, then the county flags it because the profile does not match the original. We have pulled too many doors out of dumpsters on Kentfield jobs. We quote the design-review-compliant door from the start.
Pricing for Door Installation in Kentfield, CA
Here are honest numbers for the Kentfield market. A standard pre-hung entry door runs $1,200 to $2,400 installed, assuming the rough opening and framing are sound. A double French door with re-squaring and re-flashing on a hillside lot runs $3,800 to $6,500. Custom wood-clad entry doors with period muntin patterns, true-divided lites, and a fire-rated jamb run $7,000 to $14,000 depending on the species, the hardware, and the design-review requirements. The county review itself does not add much cost, but the door that passes review does.
We give written line-item quotes before any work starts. The price on the quote is the price on the ledger. Call (888) 635-0804 for a free estimate in Kentfield, and we will walk the opening and give you the real number.

FAQs - Door Installation in Kentfield
Yes. Kentfield is unincorporated Marin County, so any replacement door on a visible elevation is subject to the County’s design-review process. The reviewer will check the door profile against the original or historically appropriate style for the house. A door that matches the home’s character passes. A generic off-the-shelf unit can be sent back for revision. We quote the door that will pass before we order it. Call (888) 635-0804 for an estimate that accounts for Marin County review from the first sheet.
Homes on Kentfield’s upslope lots fall inside California’s Very High Fire Hazard Severity Zone, which means exterior doors must meet state fire-resistance standards. That typically requires a fire-rated door slab or assembly, and in some cases a steel or clad-wood fire-rated jamb. We do not guess on this. We pull the parcel’s hazard-zone designation and specify the door to match, then register both warranty layers in writing before we leave. Call (888) 635-0804 and we will check your parcel while we are on the phone.
You check the king studs behind the sill pan, which is what we do on every Kentfield door job before quoting the work. The tell from inside is a door that has shifted against the jamb or a threshold that feels soft underfoot. On the wooded lots near Crown Road, redwood duff holds moisture against the sill for months, and rot that starts in the jamb often travels into the framing. We sister new framing when we find it, and we install a sloped sill pan with flashing tape so it does not recur. For an exact assessment, call (888) 635-0804 for a free door and framing inspection.
It depends on the elevation and the door profile. A flush fiberglass door with a contemporary profile can trigger design-review revisions on a Craftsman or Tudor home. A fiberglass door with a wood-grain texture, period-appropriate panel layout, and the right lite pattern often passes. The county cares about how the door looks, not just what it is made of. We quote doors that satisfy both the homeowner’s budget and the county’s review. Call (888) 635-0804 for a written side-by-side comparison of wood-clad and fiberglass options that will pass Kentfield review.
Winter sticking is usually the frame, not the hinges. Cold wet months soften the soil under a Kentfield hillside slab, the downhill side settles another fraction of an inch, and the jamb goes out of square. You can adjust hinges forever and the doors will still bind. The fix is re-squaring the jamb, resetting the threshold, and sometimes adding a steel strap to stabilize the header. We do that work on Kentfield hillside doors regularly. Call (888) 635-0804 and we will come look at the actual framing, not just the hinge screws.
