We know San Anselmo’s housing stock. The 1920s bungalows near downtown, the 1960s ranchers off Butterfield Road, the hillside homes up Red Hill and Sleepy Hollow. Each era of construction has its own door framing quirks, and we’ve pulled enough old jambs apart to know exactly what’s waiting behind them. Our Door Replacement team works all over San Anselmo, from Seminary neighborhoods to the flats along Sir Francis Drake Boulevard.
Why Juniper Windows & Doors Is San Anselmo’s Preferred Door Replacement Company
Sean Mackey leads our San Anselmo door replacement work, and he’s built a reputation for showing up when he says he will and leaving a clean job site. That’s not a small thing when you’ve got a front door open to the elements and a work schedule to manage.
We’ve replaced doors across San Anselmo for years, and the reviews from local customers consistently mention three things: the written price matched the final invoice, the crew communicated throughout the day, and the old door and framing debris were gone before the truck pulled away. Dispatch and scheduling are coordinated from our San Francisco Bay Area office, but the crews who show up at your door are local, uniformed, and background-checked. You’ll get a live arrival time you can track on your phone, photo updates while the work is underway, and a digital invoice you can pay from a link. That’s the Relay Standard, and it applies to every job we do.
No four-hour windows. No “we’ll be there sometime Tuesday.” No surprise change orders at the end. If it’s not done right, our 365-Day Done Right Promise covers parts and labor, in writing, for a full year after installation.
Door Contractors in San Anselmo
Door Contractors in San Anselmo handle everything from a straightforward slab swap to a full rough-opening reframe. When you hire Juniper, you’re getting a specialist, not a general remodeler who does doors on the side. We only do windows and doors, which means we’ve seen nearly every framing condition San Anselmo’s older homes can throw at us. Our San Anselmo Window Installation work runs alongside our door projects, so the same crew handles both. A typical door contractor job in San Anselmo runs $1,200 to $4,800 depending on door size, material, and whether the existing frame needs work.
What the Crew Actually Does
We start by pulling the interior casing to inspect the rough opening. That’s where the real condition of the job reveals itself: dry rot, improper flashing, shims that have compressed over decades. Then we remove the old slab and jamb, address any framing problems, set the new pre-hung unit square and level, insulate the gap, and flash the exterior properly. Exterior trim goes back on, caulk goes in, and the door gets adjusted until it latches cleanly and seals tight.
When to Call a Contractor Versus Doing It Yourself
If you’re swapping a same-size door with a pre-hung unit and the opening is in good shape, a skilled homeowner might manage it in a weekend. But if the door is out of square, the sill has rot, or you’re changing the door’s size or location, this is not a DIY job. A licensed contractor knows when a permit is required and stands behind the work with a written warranty. In San Anselmo, that distinction matters more than most places because of the Building Division’s specific permit triggers.
Door Frame Repair in San Anselmo
Door Frame Repair in San Anselmo is often the smarter move when the slab itself is fine but the jamb or threshold has failed. We see this constantly in homes built before 1980, where years of winter rain and inadequate flashing have compromised the wood around exterior doors. A frame repair typically runs $400 to $1,200 when we can salvage the existing door and only replace the jamb legs, sill, or brickmold.
Signs Your Frame Needs Attention
If the door sticks in the corner, the threshold feels soft underfoot, or you can see daylight around the edges when the door is closed, the frame is telling you something. Water stains on interior baseboards near the door are another red flag. These issues compound quickly in San Anselmo’s wet winters, so catching them early saves real money.
When a Full Replacement Makes More Sense
If the rot has spread into the rough-opening framing, if the header is cracked, or if you want to upgrade to a wider door or add sidelights, a frame repair isn’t enough. In those cases we reframe the opening, pull the necessary permit through San Anselmo’s Building Division, and install a new pre-hung unit that’s flashed and insulated correctly for the long haul.
One job on San Anselmo Avenue sticks with us. The owners called about a sliding patio door that was hard to operate and drafty. We assumed a simple replacement. When we pulled the old jamb, we found dry rot in the rough opening sill and a cracked header from years of water intrusion. We reframed the opening, added new flashing, and installed a Therma-Tru fiberglass unit with low-E glass. Catching that rot before it spread to the floor framing saved that homeowner thousands.
Trusted Brands We Service in San Anselmo
We install and service doors from CWS, CGI, and ES Windows, and we keep parts for these lines accessible for our San Anselmo customers. That means when a roller fails or a weatherstrip tears, you aren’t waiting weeks for a factory order. CWS makes excellent impact-rated entry doors that perform well in San Anselmo’s exposure conditions. CGI is known for their coastal-grade engineering, which matters even inland when wind-driven rain hits a west-facing door. ES Windows brings clean sightlines and modern hardware that fits San Anselmo’s mid-century homes nicely. The right door for your opening is never a compromise, because we carry eight product lines and match the door to the exposure, not the other way around.
Common Door Replacement Problems We See in San Anselmo Homes
- Dry rot in the jamb and rough opening sill. San Anselmo’s older housing stock has decades of rain exposure, and poor flashing around exterior doors lets water hang around. By the time you see rot on the surface, the framing underneath usually needs attention too.
- Unpermitted door swaps that change the door’s size or location. A homeowner replaces a single door with a French double door without pulling a permit. That works fine until they sell the house or a neighbor complains, and then it triggers a stop-work order and an inspection cycle nobody wanted.
- The wrong door for the exposure. An interior-rated door or one without proper weatherstripping on a north- or west-facing opening lets water and cold air in during San Anselmo’s wet winters. We see it on hillside homes where wind-driven rain hits the door directly.
- Out-of-square rough openings. Older San Anselmo homes settle. When the rough opening is no longer square, a pre-hung door needs shimming and adjustment that goes beyond a surface-level swap. Proper leveling now prevents sticking and air gaps later.
Pricing for Door Replacement in San Anselmo, CA
A typical entry door replacement in San Anselmo runs $1,800 to $2,600 for a standard pre-hung steel or fiberglass unit, installed. Sliding patio doors land between $2,200 and $4,200 depending on glass package and size. French door conversions start around $3,500 and can reach $7,000 when the opening needs reframing and a new header. Door frame repair alone is $400 to $1,200. Your price depends on door material, whether the rough opening is sound or needs reframing, permit requirements, and the exposure rating the door needs. We give you a written line-item quote before any work starts, and that number does not change unless we find hidden framing damage, at which point we show you photos and get your written sign-off before proceeding.

FAQs About Door Replacement in San Anselmo
You need a permit if the replacement changes the door’s size, location, or header. A same-size, in-kind swap does not require one. That distinction trips up a lot of San Anselmo homeowners: swapping a standard 36-inch door for another 36-inch pre-hung unit, no permit. Widening the opening for a French double door, that’s a permit and an inspection cycle. We handle the permitting for you on every job that requires it. Call (682) 281-2168 and we’ll tell you upfront which category your project falls into.
Most same-size door replacements take one day from tear-out to final trim. A project that changes the door’s size or involves reframing typically takes two to three days plus whatever time the San Anselmo Building Division needs for inspection scheduling. We don’t promise same-day service on door replacement work because doing this properly means letting shims set, checking the seal, and often waiting on that inspection. What we do promise is a clear calendar from the day you book. Call (682) 281-2168 for a specific timeline on your project.
We install CWS, CGI, ES Windows, ECO Window Systems, PGT, Therma-Tru, and ViewLux. Brand matters in San Anselmo because the exposure on the west side of town, up near the hills, puts a door through real weather: wind-driven rain, direct afternoon sun, cold damp winters. A fiberglass door from Therma-Tru with proper weatherstripping handles that differently than a builder-grade steel slab. We match the door to the opening’s exposure and to your home’s architectural era. Call (682) 281-2168 and we’ll show you what fits.
Dry rot in the rough opening sill is the one we find most often. Water gets past old flashing, sits against the wood, and for twenty years it quietly eats the framing. The door still closes, so nobody thinks twice about it. When we pull the old jamb, the wood crumbles in our hands. The fix is reframing the opening, adding proper flashing, and installing a door that seals against the next twenty winters. Call (682) 281-2168 and we’ll inspect your existing frame before you commit to any work.
Yes, if the slab is still sound and the damage is limited to the jamb legs, threshold, or brickmold. We replace the rotted sections with new wood or composite material, re-shim the door square, and reflash the opening. It typically costs $400 to $1,200. If the rot has reached the rough opening framing or the header is compromised, a frame-only repair won’t hold, and we’ll recommend a full replacement with a permit. Call (682) 281-2168 for a free assessment.
