Fast, Reliable Door Installation Across Fairfax
Door installation in Fairfax, CA usually runs $850-$4,200 depending on the door type, frame condition, and whether the home sits in a mapped WUI hazard zone. Call (888) 635-0804 to schedule a free estimate. We’ve worked on enough homes off Cascade Drive, Bolinas Road, and along the creek-side lanes of 94930 to know that Fairfax doors fail differently than doors in San Anselmo or Kentfield. Here’s why, and what we do about it.
Why TruePane Windows & Doors Is Fairfax’s Preferred Door Installation Company
Fairfax homeowners call us because the door problem they’re looking at is usually not what a big-box installer expects. The town’s location at the bottom of a redwood-shaded Ross Valley canyon keeps exterior wood damp most of the year. That’s why we see door frames on 1920s-1950s cottages that are swollen, racked, and split in ways flatland Marin towns just don’t experience. Our crews have pulled permits through the Town of Fairfax building department, know which mapped parcels trigger WUI fire-resistance requirements, and spec hardware that survives canyon moisture instead of corroding in two seasons. Our Door Installation team has handled hundreds of Fairfax homes, and the feedback we hear most is that we showed up when we said we would and the door hasn’t bound since.
We’re local dispatch, not a regional call center. When you call (888) 635-0804, a live person picks up and can talk through what you’re seeing: a latch that won’t engage, a threshold that’s split, fog between the glass panels. We keep background-checked, uniformed technicians on crews that know Fairfax’s narrow hillside streets and steep driveway approaches. That matters when a delivery truck has to navigate a switchback off Cascade Drive with a pre-hung door assembly.
Our Door Installation Services in Fairfax
Entry & Swing Doors
Entry doors take the brunt of Fairfax’s damp canyon air. Original solid wood doors from the 1940s and 1950s absorb moisture from redwood canopy drip and morning fog, then swell until the deadbolt binds. We replace them with fiberglass or steel entry systems that hold their dimension year-round, set them in a properly flashed rough opening, and use stainless-steel hinges that won’t rust out in a few seasons. A typical entry door replacement in Fairfax runs $1,200-$3,800, including frame and hardware.

Storm Doors
Storm doors in Fairfax are trickier than people expect. The same damp that rots wood also warps cheap aluminum storm door frames, and a standard vinyl storm door may not pass WUI inspection on homes mapped in the Very High Fire Hazard Severity Zone. We quote storm doors side by side on paper, including fire-rated and marine-finish options, so you see exactly what the town will sign off on. Expect $650-$1,900 for most Fairfax storm door installs.

Arched & Custom Doors
Fairfax has a concentration of craftsman bungalows and hillside cottages with non-standard openings: arched tops, odd rough-in widths, threshold heights that were never square to begin with. A true arched entry or a custom cottage door is a craft job, not a stock item. We measure every opening twice, order to fit, and set the door so the reveal is even and the latch engages without lifting the handle. Custom arched door work in Fairfax typically runs $2,800-$6,500 depending on material and finish.

Double & French Doors
Double and French doors on older Fairfax homes often bind at the meeting stile because the surrounding frame has shifted over decades. We square the rough opening, shim precisely, and hang the pair so both panels swing true. Cost ranges $1,800-$4,200 in Fairfax, and the work usually takes one day.

Trusted Brands We Service in Fairfax
We’re an authorized installer for more than a dozen manufacturer lines, and for Fairfax homes the brands that matter most are PGT, CGI, and CWS. Why those three? They all build door assemblies with WUI-compliant glazing options and frames that handle sustained moisture without swelling or corroding. When you call (888) 635-0804, we’ll quote manufacturer lines side by side on paper and register both warranty layers in writing before the truck leaves your driveway.
Common Door Installation Problems We See in Fairfax Homes
- Swollen frames and racked jambs. Redwood canopy drip keeps exterior door frames wet for months at a stretch. On a hillside cottage off Cascade Drive, our crew found a 1940s door frame so swollen the jamb had racked a full half-inch, popping the hinges and splitting the threshold.
- Fog between glass panels. Canyon damp degrades door glazing seals faster than in flatland Marin. Fog between the panes means the insulated glass unit has failed, and in many Fairfax doors the fix is a new door, not a panel repair, because the frame has already moved.
- Latches and deadbolts that bind seasonally. Wood doors swell in wet months and shrink in dry spells. Homeowners call us in the winter when the deadbolt won’t turn, then think it’s fixed by summer. A properly set fiberglass or steel door doesn’t do this.
- Standard vinyl failing WUI inspection. Standard vinyl door frames pass energy code but fail fire-resistance requirements in parts of Fairfax mapped as Very High Hazard. We’ve seen projects halted mid-permit because the spec didn’t account for it. We spec fire-rated assemblies from the first quote.
Pricing for Door Installation in Fairfax, CA
Here are the ranges Fairfax homeowners can expect for the most common door jobs:
- Storm door: $650-$1,900 installed
- Entry door (fiberglass or steel): $1,200-$3,800 installed

The two factors that push Fairfax prices higher than, say, San Rafael are the WUI-compliant door assemblies the town requires on hazard-mapped parcels and the extra labor of working on steep hillside sites where access is narrow and every tool has to be walked in. We give a written line-item quote before any work starts. Call (888) 635-0804 for pricing on your specific door, and we’ll come out and measure the opening properly.

FAQs - Door Installation in Fairfax
The canyon geography is the main reason. Fairfax sits at the bottom of a redwood-shaded Ross Valley canyon where morning fog settles and redwood canopy drip keeps exterior wood damp for most of the year. Homes in San Anselmo and Kentfield get more sun and wind, which dries surfaces out. In Fairfax, wood door frames stay wet long enough for rot to set in, and the original door units on 1920s-1950s cottages rarely had proper sill flashing. We replace rotted frames with rot-resistant or composite materials and install stainless flashing at the sill so the new door doesn’t repeat the cycle. Call (888) 635-0804 for a free estimate.
Yes, often it does. Most of Fairfax is mapped inside a CAL FIRE Very High Fire Hazard Severity Zone, and the Town of Fairfax building department applies WUI glazing requirements to door assemblies on those parcels regardless of how close the nearest open space looks from your front steps. A door with standard non-tempered glass can fail plan check and force a change order mid-project. We check the fire-hazard map for your parcel before we write the quote, and we spec a fire-rated dual-pane unit from the start when required. Call (888) 635-0804 and we’ll verify what your specific door needs.
We use stainless-steel hinges, stainless or hot-dip galvanized fasteners, and powder-coated steel or fiberglass frame components whenever possible. Standard zinc hardware corrodes in Fairfax’s persistent moisture and will seize or stain within a few years. We also set all door assemblies with flashing tape at the sill and a proper drainage path so water never has to rely on caulk alone. For an exact hardware spec on your door, call (888) 635-0804 and we’ll walk through it.
Fog between the panes means the insulated glass unit’s seal has failed, and in a Fairfax door the surrounding frame usually has failed too. The same damp that kills the seal swells the wood or corrodes the frame, which means most fogged doors we see here are beyond a simple glass replacement. You’d pay for a new glass unit now, then pay again when the frame finally gives out. A new door with a properly flashed, fire-rated dual-pane unit fixes both at once. Call (888) 635-0804 for a free assessment.
You can, but it’s usually a poor fit for Fairfax’s specific conditions. Standard vinyl storm doors pass energy code but many fail WUI fire-resistance requirements on hazard-mapped parcels, and cheap vinyl frames are not stiff enough to hold square on a hillside cottage whose rough opening has shifted over decades. By the time you’ve paid for the door, the call-back, and the second install with a compliant unit, you’ve spent more than a fire-rated storm door would have cost on day one. Call (888) 635-0804 and we’ll quote both options side by side so you can see the real math.
