Fast, Reliable General Contractor Across Alum Rock
Hiring a General Contractor in Alum Rock means finding someone who understands that this unincorporated pocket of east San Jose plays by different rules than the city neighborhoods next door. Most Alum Rock homes are mid-century stucco-and-wood-frame builds from the 1950s through 1970s, sitting on the alluvial fan below the Alum Rock hills. That combination of age, hillside proximity, and county jurisdiction means remodels here frequently turn into legalization and code-upgrade work. We handle that reality up front, with inspection-first walkthroughs and written allowances so you’re never blindsided after demo starts. Call us at (866) 472-1908 to schedule a free estimate.
Why San Bruno Construction Is Alum Rock’s Preferred General Contractor Company
We work on enough Alum Rock parcels to know exactly what the county will flag during inspection. That’s not something a contractor who primarily builds in incorporated San Jose can say with confidence. Alum Rock homeowners call us because we’ve pulled Santa Clara County permits on older ranches where informal additions and second units were built decades ago without paperwork. We keep that process moving instead of letting it stall your project.
Noel Carvalho, owner at San Bruno Construction, has built the company around a simple idea: one contractor, every phase, from countertops to rooflines to ADUs. We coordinate the licensed trades so you don’t have to. That matters doubly in Alum Rock, where a kitchen remodel can quickly become a structural repair and a permit legalization. You don’t need three separate vendors pointing fingers. You need one accountable team that priced the unknowns into the contract before the walls came down.
We serve the entire 95127 ZIP, from the flats near Alum Rock Avenue up to the slope-adjacent parcels along Mt. Hamilton Road and the streets climbing toward Alum Rock Park. Our strongest Alum Rock reviews come from homeowners who’d been burned by change-order surprises on previous projects and appreciated that our written line-item quotes named the likely code upgrades before we started.
Styles & brands we work with







General Contractor Services in Alum Rock
General Contractor Services in Alum Rock span kitchen and bath remodels, whole-home renovations, room additions, garage conversions, and ADU construction. On a mid-century Alum Rock home, the work almost always starts with an honest look at what’s behind the drywall: cloth wiring, undersized joists, failed waterproofing, and additions that never hit the county record. We write allowances for those findings into your contract. Surprises get priced and approved in writing before we touch them. A kitchen remodel in Alum Rock typically runs $14,000 to $45,000, while a bathroom remodel lands between $9,000 and $28,000.
Kitchen and Bath Remodels With Code Upgrades Baked In
Opening a 1960s Alum Rock kitchen usually triggers electrical panel upgrades and insulation requirements under current California energy code. We plan for that. Our cabinet lines from KraftMaid and Wellborn, paired with Cambria or Silestone countertops, give you real material choices without forcing a premium-only budget.

Additions and Legalization of Existing Work
Home additions in Alum Rock run $45,000 to $130,000. When an existing addition was built without county permits, we fold the legalization scope into the addition contract so the whole building gets signed off together.

Construction Company in Alum Rock
As a full-scope Construction Company serving Alum Rock, San Bruno Construction manages interior remodels, exterior envelope work, hardscaping, and new structures under one contract. That range matters here because Alum Rock’s concentrated winter rains expose hillside seepage and retaining-wall failures right after the first storms. A remodel that ignores drainage and foundation waterproofing fails within a season. We include those scopes when the site calls for them. Driveway and hardscape work on Alum Rock slopes also requires grading you don’t see on flat San Jose lots.
Slope-Adjacent Site Work
Parcels climbing toward the Alum Rock hills often need retaining wall repair, drainage swales, and foundation waterproofing before interior work makes sense. We sequence those trades so the structural work gets inspected and signed off before finishes go in.
Exterior Envelope and Hardscape
Roof replacement in Alum Rock runs $8,000 to $20,000. Paver patios land between $3,500 and $11,000. On hillside lots, we coordinate roofing, siding, and drainage scopes together so the water management system works as one piece.
Trusted Brands We Service in Alum Rock
We bring access to 50+ vetted product brands to every Alum Rock project, so your budget decisions aren’t forced into whatever a contractor happens to stock. For kitchens, that means cabinet lines from KraftMaid and Wellborn paired with Cambria and Silestone countertops. For bathrooms, Kohler, Grohe, and Toto plumbing fixtures. For roofing, GAF and CertainTeed. For the exterior envelope, James Hardie siding and PGT impact windows. ADU and prefab builds come through Abodu, Dvele, Mighty Buildings, Boxabl, and Plant Prefab. You choose from real options. We coordinate delivery, install, and warranty registration.

AfterCommon General Contractor Problems We See in Alum Rock Homes
- Unpermitted additions and second units. Alum Rock has a long history of informal construction that never hit county records. A remodel often triggers legalization before final sign-off.
- Cloth wiring and outdated electrical. Mid-century homes throughout 95127 still carry original wiring that fails current code the moment walls open. Panel upgrades and rewiring become part of the permit scope.
- Undersized framing over spans. We regularly find ceiling joists and headers that were sized for 1950s loads, not modern insulation and tile. Structural upgrades come out of the same inspection-first review.
- Hillside water and retaining walls. Winter rains shed fast off the Alum Rock hills. Foundation seepage and wall failures show up right after the first storms, so drainage belongs in the original scope, not a change order.

FAQs About General Contractor in Alum Rock
Alum Rock is unincorporated Santa Clara County territory, so your permit goes through the county, not the city of San Jose. An inspector may flag informal additions or unpermitted second units that were never on record, which triggers a legalization process before final sign-off. We handle that with the county directly. Call (866) 472-1908 for a free walkthrough and we’ll tell you what your parcel will trigger.
Cloth wiring, undersized framing, and prior unpermitted work are the three biggest drivers. We write allowances into your contract for those items after an inspection-first walkthrough, so a change order is priced and approved in writing before work continues, not sprung on you after demo. Call (866) 472-1908 if you want that process from the start.
Yes. Legalization means opening the work far enough for a county inspector to verify framing, electrical, and plumbing, then correcting any deficiencies to current code. It’s common on Alum Rock parcels where informal additions were built decades ago. We’ve done it on ranches off Mt. Hamilton Road and throughout 95127. Call (866) 472-1908 for an exact quote on your property.
We sequence drainage, foundation waterproofing, and retaining-wall repair into the original scope if the site needs it. Alum Rock’s concentrated winter rains expose seepage fast, so installing finishes before the water management is right means doing the job twice. Call (866) 472-1908 and we’ll walk your lot.
A kitchen remodel in Alum Rock typically runs $14,000 to $45,000. A bathroom remodel lands between $9,000 and $28,000. Both ranges include our inspection-first review and written allowances for the code upgrades older homes in 95127 usually trigger. Call (866) 472-1908 for a free, line-item estimate.
