If you’re planning a kitchen gut, a full home remodel, or an ADU in 95110, 95112, or the surrounding ZIPs, you already know this market runs on tight lots, strict planning review, and housing stock that ranges from century-old Victorians to mid-century ranch homes. One contractor handles every phase, from the cabinets to the roof, with brand-name materials and a written scope that holds up to inspection and insurance review.

Why Toolbox Contractors Is San Jose’s Preferred Home Remodeling Company

San Jose homeowners don’t have time to coordinate five separate specialists. They want one accountable general contractor who knows the city’s seismic codes, historic review boards, and Title 24 energy requirements. That’s what we do. Our Home Remodeling team has worked through gut renovations in 95110 and 95112 where knob-and-tube wiring, galvanized supply lines, and soft-story framing hide behind lath and plaster. We pull permits up front, run the lateral bracing and shear detailing inspectors look for, and hold every allowance and change order in writing.

Norm Castellano leads our crews with a straight answer first and a written scope second. That matters when a planning review stretches a Willow Glen tear-down by weeks. We don’t bluff the timeline and we don’t bury the contingency. What we quote is what the job actually requires, documented for the building department and for your insurer.

We’re not a single-trade outfit asking you to find your own plumber, electrician, or roofer. From KraftMaid cabinets and Cambria countertops to GAF roofing systems and PGT impact windows, the same contract carries the whole remodel. Here’s how that plays out in San Jose: a kitchen gut on one side of the house, a roof replacement on top, an ADU in the back, and one draw schedule for all of it. Our San Jose customers keep one point of contact from the permit counter to the final inspection.

Homeowners here recognize brand names. We carry vetted lines like Cambria, Caesarstone, Kohler, Moen, and Toto because our customers ask for them by name. The material depth means you’re not stuck choosing from a generic catalog, and the pricing ranges we give below reflect what these materials actually cost in this market.

Luxury Home Remodeling in San Jose

Luxury Home Remodeling in San Jose usually means a full-gut kitchen and primary bath, premium countertops, high-end fixtures, and structural work that brings the seismic load path up to what the city now requires before drywall closes. In neighborhoods like Willow Glen and Naglee Park, a luxury remodel often runs $16,520 to $53,100 for the kitchen alone, with bathrooms landing between $10,620 and $33,040. Cambria and Caesarstone countertops, Grohe and Toto fixtures, and KraftMaid or Wellborn cabinetry are standard asks on these jobs.

Kitchen and Bath Scope

We open load-bearing walls, reframe the rough openings, and run new electrical and plumbing before the finish materials go in. On a Willow Glen bungalow near the downtown core, our crew opened a load-bearing wall between kitchen and dining and found knob-and-tube wiring and old galvanized supply behind the lath, forcing a rough-in update before the new KraftMaid cabinets and Cambria counters could go in. We pulled the permits up front, ran the lateral bracing and shear detailing the inspector wanted at the opened wall, and held every allowance and change order in writing.

Whole-Structure Finishes

A luxury remodel often extends beyond one room. We install PGT impact windows, replace exterior doors with Therma-Tru, and top the structure with a GAF or CertainTeed roof system when the scope calls for it. One crew handles the interior and exterior, so the scheduling doesn’t stall waiting on a sub.

Full Home Remodel in San Jose

A Full Home Remodel in San Jose is the path when you’re buying an older home in 95110 or 95112 and planning to gut it rather than tear it down. The job spans kitchen, baths, windows, roof, and often an ADU. Kitchen work in this scope typically runs $16,520 to $53,100, a full bathroom remodel $10,620 to $33,040, and a roof replacement $9,440 to $23,600. If you’re adding square footage, a home addition starts around $53,100 and can reach $153,400.

Tight-Lot Rebuilds

Most San Jose lots don’t give you room to expand outward, so a full remodel means working inside the existing envelope and sometimes building up. The Santa Clara Valley clay under these homes can shift, and older foundations in the downtown core often need seismic retrofit attention before vertical work begins. We budget for that in the initial estimate, not as a surprise change order after demolition exposes the slab.

ADUs and Detached Work

Backyard ADUs are the most common full-scope addition we handle in San Jose, with construction ranging from $106,200 to $259,600. Through partnerships with Abodu, Dvele, and Boxabl, we offer prefab structures that cut site time and work within the city’s strict planning reviews. The same contract can carry the main house remodel and the ADU, which keeps permitting and sequencing cleaner.

Trusted Brands We Service in San Jose

We install and service materials from brands San Jose homeowners already know and ask for: PGT impact windows for the wind and seismic zones, CGI for rated openings, Tamko and Boral for roof and exterior systems. Because we stock and order these lines directly for San Jose jobs, turnaround on replacements and material changes is faster than a contractor who has to call around town mid-project. The 50+ brand partnerships span cabinets, countertops, roofing, windows, doors, fixtures, fencing, pavers, and siding, so the scope doesn’t force you into whatever the local supplier happens to have in the yard that week.

Common Home Remodeling Problems We See in San Jose Homes

  • Knob-and-tube and galvanized in the 95110 – 95113 core. Century-old Victorians and Craftsman bungalows routinely hide cloth-wrapped wiring and corroded supply lines behind lath and plaster. A gut remodel has to budget for a full rough-in update, not just a fixture swap.
  • Lateral bracing gaps where walls were opened before. San Jose’s governing structural loads are seismic, not snow. When a previous owner opened a load-bearing wall without shear detailing, the inspector will flag it, and the fix has to happen before drywall closes.
  • Shrink-swell clay under slabs. The Santa Clara Valley’s clay soils move between wet and dry seasons. Older foundations in the flatland ZIPs often show cracking that needs evaluation before we set new structural members.
  • Historic review conflicts on tear-downs. In Willow Glen and Naglee Park, a demolish-and-rebuild or even a deep gut has to clear character review. The neighbor’s ADU is likely under construction at the same time, which complicates staging and access on a tight lot.

What San Jose Customers Say

Trusted by homeowners across San Jose and surrounding areas.

★★★★★

"He caught an error in the engineer's drawings before it got framed, which would have been an expensive thing to discover later."

Gabriela Martinez · Verified customer
★★★★★

"The foundation survey came back dead on. Everything downstream of that being square is the reason the rest of the build went smoothly."

Oscar Flores · Verified customer
★★★★★

"He was upfront about a soil issue that added cost early rather than absorbing it and surprising us at the end."
