Most Fontana homes are 50 to 70 year old stucco-over-wood-frame tract houses. The work we do here isn’t the same as what we do in coastal LA or up in the mountains. It’s specific. And that’s the point.

Why Toolbox Contractors Is Fontana’s Preferred General Contractor Company

We’ve worked enough homes in Fontana to know exactly what fails first and what it costs to fix it right. The housing stock off Sierra Avenue, along Valley Boulevard, and throughout the older 92335 and 92336 neighborhoods is mid-century tract construction. That means original plumbing, aging roofs, and framing that’s been through decades of intense heat and wind. We write our scopes for that reality, not for a brand-new build.

Fontana customers consistently tell us the same thing: they’ve been burned by contractors who quoted low, used builder-grade materials, and disappeared when the change orders started. We don’t play that game. Every project gets a written line-item estimate, documented change orders, and materials from manufacturers we’ve vetted. When we install a roof in Fontana, we spec fasteners and flashing for the Cajon Pass wind and salt-air environment, not whatever’s cheapest at the supply yard.

Our relationship with 50+ material brands means we’re not stuck with a generic catalog. That matters when you’re replacing a roof on a 92336 tract home and the original galvanized nails are already rusting at the shank. We can pull GAF or CertainTeed roofing systems, PGT impact windows, and CGI doors without waiting on special orders. Call (855) 382-3257 and we’ll put together a scope that fits your home’s actual condition.

Hire a General Contractor in Fontana

Hire a General Contractor in Fontana when your project touches more than one trade, or when the condition of your home demands someone who understands mid-century tract construction. A kitchen remodel in Fontana runs $14,000 to $45,000 depending on cabinet grade, countertop material, and whether we’re moving plumbing. A bathroom remodel lands between $9,000 and $28,000. When a homeowner asks us to also replace the roof, swap the windows, or rebuild a fence on the same house, that’s where the single-contract advantage pays off. You’re not coordinating a roofer, a window crew, and a fence installer separately.

Written Scopes and Change Orders

Older Fontana homes hide things. Original cast iron plumbing, subfloor rot under a bathroom, foundation settling in a 1960s tract house. We document everything up front and write change orders when we find something the original estimate didn’t account for. You’ll never get a surprise bill without a signed line item. That discipline matters on a $45,000 to $130,000 home addition in Fontana.

Wind-Rated Specifications

The Santa Ana winds that funnel through the Cajon Pass don’t just lift shingles; they drive salt-laden air against fasteners, hinges, and flashing 40 miles from the ocean. We spec hot-dip galvanized or stainless hardware in corrosive zones, and we specify marine-grade hinges and sealed joints on exterior doors and gates. The cheap galvanized stuff that builders used in the 1960s is already gone or failing. We don’t repeat that mistake.

General Contractor Services in Fontana

General Contractor Services in Fontana span the full envelope of a home, inside and out. For a mid-century tract house in 92335 or 92336, that often means a roof replacement at $8,000 to $20,000, windows at $4,500 to $15,000, and a kitchen or bath remodel on top of it. For newer subdivisions in 92337, we’re more likely quoting impact windows at $8,000 to $25,000 or a backyard ADU at $90,000 to $220,000. The build type changes the scope, and we adjust accordingly.

Interior Remodels

A Fontana kitchen remodel typically involves pulling original cabinetry, often reworking plumbing and electrical in a 60-year-old wall, and installing new cabinets, counters, and fixtures. We install KraftMaid and Wellborn cabinetry, Cambria and Caesarstone countertops, and Kohler or Moen fixtures. Bathrooms get Schluter tile systems and proper waterproofing under walk-in showers, which run $4,500 to $12,000 in this market.

Exterior Envelope Work

Roofing, windows, siding, and fencing all take a beating in Fontana’s heat and wind. Roof repair runs $400 to $1,800, while a full replacement on a typical Fontana ranch sits between $8,000 and $20,000. Vinyl fence installation runs $3,500 to $9,000, and aluminum fence runs $4,000 to $10,000. We install PGT and CGI impact windows, GAF and CertainTeed roofing systems, and we’re certified to back those manufacturers’ warranties.

Trusted Brands We Service in Fontana

We work with manufacturers whose products actually hold up in Fontana’s climate: PGT and CGI for impact-rated windows and doors, plus Tamko and Boral for roofing and trim systems. We keep relationships with local supply yards in the Inland Empire so we can pull common SKUs fast and avoid the wait that comes with special orders. When a Fontana homeowner needs a specific material spec, like stainless hardware or marine-grade hinges on exterior doors, we know exactly which brand to order and we’ve installed enough of it to stand behind the work.

Common General Contractor Problems We See in Fontana Homes

• Rusted galvanized fasteners on roofs and fences. The salt-laden air that pushes inland from the Cajon Pass wrecks builder-grade galvanized nails and hinges years before the material itself fails. On a tract home off Valley Boulevard, we found roofing nails rusted at the shank and fascia soft enough to fail a probe test. We replaced them with hot-dip galvanized and stainless.
• Mid-century framing meeting modern remodels. A 60-year-old stucco-over-wood-frame home in 92336 has original plumbing, settling, and sometimes subfloor rot. Cutting into those walls for a kitchen or bath remodel without a written scope and change order process is how budgets blow up.
• Wind-lift roof and exterior damage along the northern edge. Homes closer to the base of the Cajon Pass see more lifted shingles, damaged fascia, and failed flashing than homes in the southern 92337 subdivisions. Builders who don’t account for wind exposure spec the wrong fasteners.
• Applying residential assumptions to commercial builds. Fontana’s logistics warehouses are tilt-up concrete, not wood-frame stucco. If a contractor only knows tract homes, they’re lost on a commercial project. We work both build types, and the scopes look nothing alike.
