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

Sebastopol homes aren’t cookie-cutter. You’ve got 1920s bungalows off Main Street, 1970s ranchers in the Hessel area, and newer builds east of town near the orchards. We’ve worked on all of them. Customers around Sebastopol consistently tell us the same thing: they wanted a contractor who would show the actual price in writing, not float an estimate that creeps upward after demo starts. That’s how we operate. Every quote from Juniper Windows & Doors is line-item specific and locked before we order materials.

Sean Mackey leads our crews, and he’s built the Sebastopol book of business on one habit: showing up when the live arrival time says we’ll be there, with background-checked technicians in uniform. The 365-Day Done Right Promise backs every installation, covering parts and labor in writing for a full year. If something isn’t right, we return and fix it. No charge, no argument. That guarantee matters in a town where fog, rain, and old framing test doors harder than most places in Sonoma County.

Interior Door Replacement in Sebastopol

Interior door replacement in Sebastopol typically runs $350 – $1,200 per opening, including the slab, hinges, hardware, and trim work where needed. Older homes near downtown often have non-standard rough openings, so we cut and route slabs to match rather than forcing a stock door into a frame that’s settled out of square. That’s the kind of detail that separates a clean, silent close from a door that rubs the jamb every July when the humidity spikes.

Slab-Only Swaps

If your existing frame is square and solid, we can replace just the slab, which keeps the job to the lower end of that range. We measure the existing hinge mortises and bore placements so the new door drops in without patching or repainting the jamb. This works well for hollow-core doors that have been kicked in, scratched by pets, or simply look dated.

Pre-Hung Replacements

When the jamb itself is split, water-stained, or out of plumb, a pre-hung unit is the better fix. We pull the old casing, set the new frame with shims, and re-trim both sides. In Sebastopol’s older pier-and-post homes, floors often slope, so we plane the bottom of the door to follow the floor line and keep the reveal consistent. Expect the upper end of the range when the frame is replaced.

Interior Door Installation in Sebastopol

Interior door installation in Sebastopol covers new openings where no door existed before, which most commonly happens during bedroom additions, pantry conversions, or when homeowners carve a laundry room out of a garage. Pricing lands between $350 and $1,200 per door for standard interior units, but new openings add framing, drywall, and trim work that pushes the total higher depending on wall construction. We’ll give you that number in writing before cutting the first stud.

New Openings in Existing Walls

Cutting a new doorway into an interior wall is rarely just drywall work. Sebastopol homes built before 1980 often have plaster over wood lath, and some load-bearing walls need a header sized for the span. We check the wall before quoting so the price you approve is the price you pay. Our techs handle the framing, drywall patch, and trim, and we leave the room broom-clean.

Closet and Pantry Doors

Bifold and barn-style doors are common in Sebastopol homes where square footage is tight and swing clearance is scarce. We install both, along with pocket doors where the wall allows. The hardware matters more than most people expect; cheap rollers bind and rattle within a year. We stock heavier-duty tracks and soft-close kits that hold up to daily use.

Trusted Brands We Service in Sebastopol

We install and service doors from CGI, CWS, and ES Windows, three product lines that hold up well in Sebastopol’s wet winters and windy spring afternoons. Because we’re part of the Relay Home Co. family, we have access to parts and warranty support that smaller shops can’t touch. If a roller wears out or an astragal seal tears on a CWS sliding door off Gravenstein Highway, we can usually get the part within days rather than weeks. We also work with Therma-Tru for fiberglass entry doors, which resist rot better than wood in damp conditions common around the Laguna de Santa Rosa.

Common Door Replacement Problems We See in Sebastopol Homes

After two decades of installation work, certain issues show up again and again in Sebastopol. Here’s what we find when we pull the trim back:

  • Rotted jambs and thresholds from wet winters. Sebastopol gets real rain, and when door flashing fails, water wicks into the framing and sits there for months. By the time you see soft wood, the damage usually extends past what a simple sealant bead can fix.
  • Foggy insulated glass units. That grey haze between the panes means the seal has failed. It’s common enough that we stock replacement IGUs for the doors we service, which keeps turnaround shorter than ordering from a regional distributor.
  • Improper flashing around sliding door tracks. Sliding glass doors in older Sonoma County homes often sit directly on the subfloor with no pan flashing underneath. Water follows the track, rots the plywood, and eventually the whole threshold sags. Proper replacement means pulling the door and rebuilding the sill with a sloped, flashed pan.
  • Settled frames that bind in summer. Sebastopol’s clay-rich soil expands and contracts with moisture. Door frames shift. A door that swings fine in December may not latch in August, which is why we check opening dimensions seasonally on repeat service visits and plane or shim as needed.

Pricing for Door Replacement in Sebastopol, CA

Here are honest Sebastopol ranges, not teaser numbers. Exterior entry doors run $700 – $2,800 installed, with fiberglass from Therma-Tru landing in the middle and custom oversized units at the top. Sliding glass doors start around $1,200 and climb past $3,500 for impact-rated or oversized models. Interior doors sit between $350 and $1,200 per opening. What moves the price? Frame damage you can’t see until demo, permit fees through the City of Sebastopol Building Department, and glass upgrades like low-E or laminated interlayers. A written quote for your specific door and existing frame takes about an hour to put together. Call (682) 281-2168 for your free estimate, and you’ll have the number in writing before you commit to anything.
