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

Sean Mackey built Juniper Windows & Doors on a pretty simple idea: write the price down before the first screw leaves the truck. That commitment matters in Novato, where a door quote that drifts upward at installation is a real pain point we hear about constantly. Our 365-Day Done Right Promise covers parts and labor in writing for a full year after installation. If something isn’t right, we come back and fix it. No charge, no argument.

Every technician who shows up at your Novato home is background-checked and uniformed. You’ll get a live arrival time you can track, before-and-after photos of the work, and a digital invoice you can pay from your phone. That’s the Relay Visibility Guarantee, and it applies to every job we do. Whether you’re off Ignacio Boulevard or tucked into the hills above Hamilton Field, we coordinate scheduling from our San Francisco Bay Area office and serve Novato locally with crews who know this terrain.

Door Contractors in Novato

Door Contractors in Novato handle the full replacement job: removing the old slab and frame, addressing any hidden rot or water damage, setting the new pre-hung unit, insulating, sealing, and trimming out the opening. You need a licensed contractor when the rough opening is out of square, when WUI fire-rated assembly rules kick in, or when the existing jamb has water damage you can’t see from the surface. A straightforward slab swap on a clean opening typically runs $900 to $1,600 in Novato. A full pre-hung replacement with new casing and threshold work generally lands between $1,800 and $3,200, and can go higher with sidelites or custom glass.

Entry System Replacement

Most Novato homes we visit have wood jambs that have been soaking up Marin fog for two or three decades. Replacing just the slab without addressing the jamb is a short-term fix. We scope the full opening, check the king and jack studs, and build the new unit to spec. If the door faces west toward the coastal fog line, we’ll recommend a rot-resistant composite jamb instead of wood. That detail alone can add ten years to the install.

WUI-Compliant Door Installations

Novato sits inside Marin County’s Wildland-Urban Interface, which means exterior door replacements in many neighborhoods must meet fire-rated assembly standards. That includes the door slab, the glazing, and sometimes the frame hardware. We handle the paperwork and coordinate with Marin County building inspectors so the door passes the first time. Miss this step and you’re reordering product and living without a front door for another three weeks.

Door Frame Repair in Novato

Door Frame Repair in Novato comes down to one recurring problem: fog and winter rain get into wood jambs, soften the bottom hinge area, and the whole door starts to sag or stick. We see it constantly in the Ignacio and Hamilton corridors, where marine air hangs around longer than it does up in the dryer hills. Repair usually involves cutting out the rotted section, splicing in new wood or composite, re-shimming, and resetting the hinges. A localized jamb repair at the bottom typically costs $350 to $700 in Novato. Full jamb replacement on both sides runs $800 to $1,400, depending on whether the threshold and brickmold need to come out too.

Rot Repair and Jamb Splicing

When fog and rain rot the bottom six to twelve inches of a door jamb, you don’t always need a full replacement. We cut out the damaged section, treat the exposed framing, and splice in rot-resistant material that won’t absorb moisture the way the original wood did. The repair is structural, not cosmetic, and we prime and paint the splice so it blends into the existing trim.

Threshold and Weatherstripping Correction

A door that closes but still lets fog-cooled air slip under the bottom rail is a frame alignment problem, not a door problem. We check the threshold height, the sweep, and the weatherstripping to close the gap. In older Novato homes with settling foundations, the fix sometimes means re-leveling the threshold and adjusting the strike plate. It’s a smaller job, usually $200 to $450, and it makes an immediate difference on foggy mornings.

Trusted Brands We Service in Novato

We stock and install PGT, CGI, and Therma-Tru doors, so Novato homeowners aren’t stuck waiting on a warehouse in another county. If you have a PGT entry system with impact-rated glass, we know the hardware, the hinge specs, and the glazing requirements. If you’re replacing a tired wood door with a Therma-Tru fiberglass unit, we can match the grain and finish to your existing trim. We don’t push a door you don’t need. We’ll tell you which brand fits your exposure, your WUI zone, and your budget, then write the price down so you can decide on facts.

Common Door Replacement Problems We See in Novato Homes

• Fog-belt rot in wood jambs. The Ignacio and Hamilton areas catch more fog than the rest of Novato, and that moisture works its way into bottom hinge pockets. Within a few years, the door sags, sticks, or won’t latch. The fix is a rot-resistant composite jamb with proper flashing, not another pine jamb that’ll rot the same way.
• WUI fire-rated assembly oversights. Homes built before 1995 often have original doors that don’t meet current Marin County WUI codes. Replacing an exterior door without checking the fire-rating requirement leads to a failed inspection and a reorder. We verify the assembly spec before we quote so there’s no surprise at the end.
• Water intrusion behind stucco and siding. Older Novato homes frequently lack pan flashing under the door threshold. Water gets behind the stucco or siding, rots the sheathing, and you only see it once the old door is out. We install proper pan flashing and sealant on every exterior door replacement, because skipping it just moves the problem deeper into the wall.
• Swollen door slabs from seasonal humidity swings. A wood door that fits fine in September might bind in February after a wet winter. If you’re already replacing the door, we’ll steer you toward fiberglass with a composite jamb so the door moves less with Marin County’s seasonal moisture.
