Fast, Reliable General Contractor Across San Juan Bautista
If you’re searching for a General Contractor in San Juan Bautista who understands adobe walls, historic review boards, and coastal fog as well as they understand modern framing, you’re in the right place. We work on 1800s adobes near the Mission, mid-century homes off The Alameda, and rural ranches on the town’s edges. Our team manages the entire scope under one contract, from structural retrofits to kitchen cabinetry. Call (855) 901-7266 to start with a free estimate.
San Juan Bautista isn’t a tract-home suburb. It’s a town of roughly 1,900 people where a kitchen remodel might require a hidden steel moment frame before a single cabinet goes in. We know that going in. It changes how we bid, how we schedule, and how we talk with the historic review board. That local fluency saves you weeks and thousands in rework.
Why San Mateo Construction Is San Juan Bautista’s Preferred General Contractor Company
San Juan Bautista homeowners call us because we’ve already done the hard learning curve on their exact housing stock. We’ve pulled permits through the State Historic Park design review process for Mission-adjacent properties. We’ve matched lime plaster on adobe walls. We’ve sistered floor joists in 1890s wood-frame Victorians where the original lumber had dry rot from a century of fog-influenced winters. That experience means our bids from day one include the structural and preservation work other contractors discover halfway through, then bill as surprise change orders.
Noel Carrington leads our team with a straightforward approach: we tell you what your house actually needs, not what pads the invoice. San Juan Bautista customers regularly mention that our written line-item quotes match our final invoices. When the 1890s adobe near the Mission required an unplanned steel moment frame, the change order was written and approved before we touched a single cabinet. That’s how we work. We also carry the full exterior-to-interior scope: the same crew responsible for re-roofing your house can rebuild the kitchen, replace the windows, and pour a paver driveway. One accountable team, not a patchwork of subcontractors pointing fingers.
Styles & brands we work with







Construction Company in San Juan Bautista
As a Construction Company working throughout San Juan Bautista, we handle the structural and envelope work that keeps your house standing straight and dry: foundations, seismic retrofits, roofing, windows, additions, and full exterior re-sheathing. Homeowners here come to us when a house has outgrown its floor plan, when old foundations show cracks from expansive soils, or when an un-reinforced masonry (URM) building near the Mission needs a modern retrofit that won’t alter its historic character. A home addition in San Juan Bautista runs $45,000 to $130,000 depending on scope, and a roof replacement lands between $8,000 and $20,000 based on material and structural condition.
Seismic and Foundation Scope
San Juan Bautista sits near the San Andreas Fault, and the valley’s expansive soils heave and settle with seasonal moisture. We routinely install shear walls, foundation anchors, and moment frames in older adobe and wood-frame houses. The goal is a house that stays plumb and safe through the next quake, not one that just looks better.
Rural and Ranch Property Work
On the town’s edges, we work on ranches and rural parcels off San Juan Highway and Monterey Street extension where septic, well lines, and long driveways add scope. We manage grading, retaining walls, and drainage as part of the same contract as the house itself.
Remodeling Contractor in San Juan Bautista
As a Remodeling Contractor in San Juan Bautista, we take older homes and make them work for modern life without erasing what makes them worth preserving. A kitchen remodel here runs $14,000 to $45,000, and a bathroom remodel lands between $9,000 and $28,000. Those numbers reflect the reality of working inside historic envelopes: uneven plaster walls, wavy subfloors, old framing that needs reinforcement, and finishes that must pass historic review.
Kitchens That Fit Old Walls
We recently finished a kitchen remodel in an 1890s adobe near the Mission where the original walls had no shear reinforcement and the subfloor was uneven from decades of settling. Our crew installed a hidden steel moment frame to satisfy URM requirements, then used KraftMaid cabinets with custom scribe molding to fit the wavy plaster. The final inspection cleared both the city and the historic review board.
Bathrooms That Handle Moisture
Fog-influenced winters mean bathroom ventilation and waterproofing can’t be afterthoughts here. We use Schluter waterproofing systems under tile in every wet area, and we spec marine-grade hardware on doors and fixtures so hinges and handles don’t pit and seize within five years.
Trusted Brands We Service in San Juan Bautista
We carry a curated portfolio of 50+ name-brand suppliers, and we help you choose what fits your house and budget. For windows and doors on San Juan Bautista homes, we regularly specify Therma-Tru entry doors for their weather resistance and ECO Window Systems and ViewLux for coastal-rated frames that won’t corrode in salt fog. We keep common fasteners, flashing, and sealants in our local stock so we’re not waiting on a parts truck from Hollister when your job is mid-install. You pick from vetted brands, not whatever happens to be on a supplier’s shelf that week.

AfterCommon General Contractor Problems We See in San Juan Bautista Homes
- Zinc-plated fasteners and mild-steel railings failing within two winters. Salt fog from the valley’s marine layer corrodes standard hardware fast. We spec stainless and hot-dip galvanized components from the start, which costs more up front but avoids a full railing or fastener replacement within a decade.
- Inland-grade window frames and exterior door hardware seizing in fog. Frames that work fine in Gilroy pit and seize here. Window replacement in San Juan Bautista runs $4,500 to $15,000, and we steer homeowners toward marine-grade frames and stainless hardware for anything facing the prevailing west wind.
- Paver patios and driveways heaving from expansive soils. Unsealed joints let seasonal moisture in, and the soil does the rest. A paver driveway here runs $7,000 to $18,000. We use flexible, sealed joint systems that move with the soil instead of cracking against it.
- Unreinforced adobe and masonry walls near the Mission failing historic review. You can’t slap a modern addition onto a URM building without retrofitting it first. We handle the seismic engineering, the historic material matching, and the review board submittals as one scope.
Pricing for General Contractor in San Juan Bautista, CA
Here’s what we actually quote in San Juan Bautista, in 2026 dollars. Every range assumes the project is coastal-spec where it matters: stainless fasteners, hot-dip steel, marine-grade frames, sealed joints. The inland-spec version of any of these jobs costs about 15 to 25 percent less on day one, but the cheap spec usually forces early replacement within a decade. We quote the honest number first, because that’s the number that holds.

What moves your number within a range: structural condition, historic review requirements, material tier, and site access. A Mission-adjacent adobe will land higher.

FAQs About General Contractor in San Juan Bautista
The fog drives salt air inland through the San Juan Valley, and that salt air attacks standard building materials hard. We spec stainless steel and hot-dip galvanized fasteners, marine-grade window and door hardware, and sealed paver joints on every exterior-facing job. Inland-grade zinc hardware corrodes within two winters here, so we don’t use it. Call (855) 901-7266 and we’ll walk you through the material spec on your specific house.
Yes. Properties within or adjacent to the State Historic Park boundaries go through design review, and any structural work on adobe or unreinforced masonry buildings requires a URM retrofit plan before permits are issued. We prepare both the engineering and the historic material matching as part of the bid, so you’re not stuck negotiating with two boards at once. Call (855) 901-7266 and we’ll check your parcel’s historic designation before you commit to anything.
A coastal-spec roof runs about 15 to 25 percent more than the same roof specified for inland conditions. The difference comes from stainless flashing, hot-dip fasteners, and underlayment rated for persistent moisture. A roof replacement in San Juan Bautista runs $8,000 to $20,000, and the coastal-spec version sits in the middle to upper end of that range. The inland-spec roof looks cheaper until the flashing rusts out and you’re re-roofing in eight years. Get an exact number at (855) 901-7266.
We write the change order before we do the work, and you approve it in writing before our crew touches anything. On a recent 1890s adobe kitchen near the Mission, the hidden steel moment frame was scoped, priced, and signed before a single cabinet came off the truck. That’s the standard, not the exception. If your house has adobe walls or a brick foundation, call (855) 901-7266 and we’ll tell you what to expect before we ever open a wall.
Expansive soils in the San Juan Valley heave and settle with seasonal moisture, which shows up as foundation cracks, sticking doors, and sloping floors. We handle foundation anchors, shear reinforcement, French drains, and re-grading as part of the same contract as your remodel. A home addition in San Juan Bautista runs $45,000 to $130,000, and drainage work is often a line item we recommend including. Call (855) 901-7266 for a free evaluation of your foundation and drainage.
