Trusted General Contractor for San Bernardino Homeowners
Finding a General Contractor in San Bernardino who can actually handle the whole job, from foundation to roofline, still means weeding through a dozen single-trade specialists. Most homeowners in the Inland Empire end up stitching together separate bids for cabinets, countertops, roofing, windows, and a fence, then spend months playing phone tag when schedules slip. That’s the problem we built Toolbox Contractors to solve. Led by Norm Castellano, our team operates as one contract and one point of accountability for interior remodels, exterior upgrades, and ADU construction across San Bernardino, Colton, Loma Linda, and the surrounding foothill communities. Whether you’re gutting a kitchen on a 1950s rancher north of the 210 or adding a backyard prefab ADU off Waterman Avenue, you’ll have one crew, one schedule, and one phone number: (855) 382-3257.
Key Takeaways
- One licensed general contractor handles interior, exterior, and ADU scope, no juggling five trade crews.
- We install materials from 50+ vetted brands including KraftMaid, Cambria, GAF, PGT, and Schluter.
- San Bernardino kitchen remodels typically run $14,000 – $45,000; bathroom remodels $9,000 – $28,000.
- Prefab ADU capability through Abodu, Dvele, Boxabl, and Plant Prefab, a capability most local GCs lack.
- Free estimates with written line-item pricing. No change orders, no surprise markup.
Styles & brands we work with
Construction Company
A construction company is the entity that pulls permits, manages subcontractors, orders materials, and carries the liability for a project. When you hire Toolbox Contractors in San Bernardino, you’re hiring a licensed general contractor with the authority to run every phase, electrical rough-in to final paint. For a full overview of what that means, see The Complete General Contractor Guide for San Bernardino Homeowners. Most construction companies in this market cap out at one trade: a roofer who won’t touch your bathroom, a cabinet shop that won’t replace the windows. We scope the whole envelope. A typical kitchen remodel here runs $14,000 – $45,000, a roof replacement $8,000 – $20,000, and a home addition $45,000 – $130,000. We coordinate it all under one contract.
One Crew, Permits to Punch List
San Bernardino’s building department has its own quirks, and we know what flies. We pull permits, schedule inspections, and keep the job moving without you chasing paperwork. When the inspector signs off, the punch list is already done.
Materials That Match the Scope
We order everything through our trade accounts, from GAF roofing systems to Schluter shower waterproofing to Cambria countertop slabs. That means no substitutions, no depot-brand surprises, and no “we’re waiting on the supplier” delays.
Remodeling Contractor
A remodeling contractor specializes in transforming existing spaces rather than building new ones from the slab up. When you need it, the scope usually feels overwhelming on day one: a 1980s bathroom in the Verdemont hills with original fixtures, a General Contractor in Loma Linda kitchen with zero storage, a Muscoy laundry room that’s now a bedroom. Toolbox Contractors handles interior remodels at every scale. Kitchen remodels in San Bernardino run $14,000 – $45,000. Small bathrooms come in around $5,000 – $12,000. Walk-in shower installations typically $4,500 – $12,000. We carry the same license for a $9,000 vanity swap as we do for a $130,000 addition.
Full Interior Scope, One Schedule
You don’t need a separate tile crew, a separate plumber, and a separate countertop fabricator. We run all of it from one schedule so the Schluter shower pan gets waterproofed before the tile crew arrives, not after.
Brand-Name Finishes at Every Budget Tier
If your budget calls for Delta fixtures and Quikrete countertops, we’ll spec them honestly. If you want Kohler, Grohe, and Caesarstone, we have direct accounts. Either way, you’re choosing from a curated catalog, not whatever’s on the shelf at the big box.
Licensed General Contractor
A licensed general contractor carries California state licensure, liability insurance, and workers’ compensation for every crew member who steps on your property. It matters because San Bernardino County sees more than its share of unlicensed operators running ads on community boards, and the homeowners who hire them end up with no permit, no inspection, and no recourse when the tile cracks. Toolbox Contractors holds active licensure and insurance, and Norm Castellano’s name is on every contract we sign. Typical projects we license and build: kitchen remodels at $14,000 – $45,000, ADU construction at $90,000 – $220,000, and paver driveways at $7,000 – $18,000.
Your Name Goes on the Permit
When we pull a permit, you’re protected. The city inspects our framing, our electrical, our waterproofing. If a problem surfaces three years later, the permit trail holds us accountable. That’s the whole point of the license.
Insurance and Warranty, in Writing
Every Toolbox Contractors proposal includes our insurance documentation, our license number, and the workmanship warranty terms spelled out. Nothing verbal. If a vendor we hire damages your property, it’s covered under our policy, not your homeowner’s insurance.
Residential General Contractor
A residential general contractor focuses on single-family homes, townhomes, and occasionally duplexes, as opposed to commercial or industrial work. When you need one, you’re usually staring down a project with multiple trades and no clear sequence: a roof replacement plus window replacement plus a fence, or a kitchen gut that includes moving a load-bearing wall. Toolbox Contractors is built as a San Bernardino residential general contractor that can run all of it under one roof, and we also serve as our General Contractor in Highland for nearby homeowners. Window replacement here typically runs $4,500 – $15,000, vinyl fence installation $3,500 – $9,000, and impact windows $8,000 – $25,000. We also handle the hard-to-coordinate combos like roofing and windows at the same time.
The Building Envelope, Start to Finish
Roof plus windows plus siding is what we call an envelope project. We install GAF and Owens Corning roofing, PGT impact windows, and James Hardie siding, so the whole exterior system is installed to the manufacturer’s specification, not pieced together by three separate crews who never talked.
Homeowners Who’ve Been Burned
If you’ve already had a contractor walk off mid-job, you’re not alone. We get those calls regularly. We come in, assess what’s salvageable, give you a written line-item price to finish the work, and then actually finish it.
Hire a General Contractor
Hire a general contractor when your project crosses more than two trades, when you need permits, or when a failed sub would mean tearing out finished work. You hire a GC because you want one person to call when the window order arrives late or the inspector flags the rough-in, which is why a General Contractor Maintenance Checklist for San Bernardino Homeowners helps you stay ahead of issues. Toolbox Contractors operates as that single accountability point in San Bernardino. Our projects range from a $2,000 – $6,500 countertop installation to a $90,000 – $220,000 ADU build. The common thread: one contract, one schedule, one phone call to (855) 382-3257 when anything shifts.
What We Actually Do During the Job
We order materials, schedule subcontractors, enforce quality at each stage, handle the building department, and keep the site clean. We also absorb the phone calls and coordination overhead so you don’t get texted by a drywaller at 7 p.m. asking where the can lights go.
The Paper Trail
Before we start, you get a written contract with a price breakdown by phase. No “we’ll figure it out as we go.” If the tile backsplash line item says $800 – $2,500, that’s what you pay unless you change the scope in writing.
General Contractor Services
General contractor services cover the full range of construction and remodel work a licensed GC performs, from a small bathroom vanity swap to a full home addition. It’s the broadest category in residential construction, and it’s where most operators overpromise. Toolbox Contractors actually delivers the full list from our home base in San Bernardino: kitchen remodels ($14,000 – $45,000), bathroom remodels ($9,000 – $28,000), roof replacements ($8,000 – $20,000), window replacement ($4,500 – $15,000), paver patios ($3,500 – $11,000), fence installation ($3,500 – $9,000), and garage conversions ($30,000 – $80,000). One crew covers all of it.
Interior, Exterior, and the Backyard
We don’t hand off the outdoor scope to a landscaping company or the ADU to a prefab middleman. Our hardscape division installs Belgard and Unilock pavers, our fencing crew runs Master Halco and Bufftech systems, and our ADU builds use Abodu and Plant Prefab structures designed for California weather and setback rules.
One Contract, Every Phase
You sign one proposal that includes every trade. If the roof needs to be done before the kitchen install, that’s in the schedule. If the window order delays the siding, that’s our problem to solve, not yours to chase.

Brands We Service
Most San Bernardino contractors have one brand they push. We maintain direct accounts and installer certifications with dozens, which means we can speak honestly about what’s worth the money. When Norm Castellano quotes a Tamko or Boral roof system, he’s installed enough of them to know how they hold up under Inland Empire sun and Santa Ana winds. We install PGT impact windows specifically because they’re engineered for wind-borne debris zones, which matters for homes near the Cajon Pass where gusts hit 60+ mph.
The same applies to our interior lines: Schluter waterproofing for wet areas, KraftMaid and Wellborn cabinetry for storage that survives daily use, and Cambria or Caesarstone for countertops that don’t stain when your teenager leaves a red pasta bowl out overnight. Whether you have a specific brand in mind or want our honest recommendation, we can help you in Colton and across the same service area with the same material depth.

- Hairline cracks spreading across the ceiling or walls. In San Bernardino’s clay-heavy soils, seasonal ground movement is common. If the cracks are widening or reappearing after you’ve patched them, a structural issue may be developing. We can assess whether it’s cosmetic settlement or something that needs an engineer’s letter.
- Your kitchen has one usable countertop and zero drawer space. You’re not remodeling for fun; you’re losing hours each week to a layout that doesn’t function. A full kitchen remodel in this market runs $14,000 – $45,000, and the return on resale in San Bernardino consistently trends higher than most of Southern California.
- Water stains on the ceiling after the last rain, or the roof is 20+ years old. Roof failures here are rarely catastrophic; they start as a $400 – $1,800 repair and become an $8,000 – $20,000 replacement if ignored. If your roof predates 2005, call us for an inspection before the next winter storm cycle.
- You’ve been told you need a new roof, new windows, and a new fence, and the bids are from five different companies. That’s exactly the scenario a general contractor exists for. Consolidating the scope under one contract usually saves 10 – 20% on coordination overhead alone, and you stop getting five different warranty phone numbers.
- Your garage is dead space and you need a home office or rental unit. A garage conversion runs $30,000 – $80,000 in San Bernardino and the ADU market is still growing fast out here. If you’ve been thinking about it for a year, the cost of waiting is a year of lost rental income.
Our Process, Step by Step
- 1
Initial call and free estimate. Call (855) 382-3257 and tell us what you’re planning. We’ll schedule a site visit, usually within a few days, and give you a written line-item estimate broken down by phase, no vague “renovation package” pricing.
- 2
Site assessment and material consultation. Norm or a senior project lead walks your home, measures everything, and talks through material options. If you want Cambria counters and KraftMaid cabinets, we’ll price them. If Delta and Quikrete fit the budget better, we’ll show you that number too. You choose from a curated list, not a generic catalog.
- 3
Permits and scheduling. We pull the necessary permits from the City of San Bernardino and schedule inspections. Every crew role, subcontractor, and material delivery gets sequenced into a timeline we share with you. If something shifts, we update you before it affects your life.
- 4
Construction. The work happens in phases, with daily cleanup and a single point of contact. We inspect at each transition, from rough framing to drywall texture to final trim, so the next trade never covers up a mistake from the last one.
- 5
Final walkthrough and warranty. We walk the finished project with you, write a punch list if anything’s off, and close it out before we collect the final payment. Your workmanship warranty is in writing, and our phone number doesn’t change when the last check clears.
How Much Does General Contractor Cost in San Bernardino?
A kitchen remodel in San Bernardino typically runs $14,000 – $45,000 depending on cabinet grade, countertop material, and whether you’re moving plumbing. A bathroom remodel sits at $9,000 – $28,000, with small bathrooms and tub-to-shower conversions falling at the lower end. Roof replacement runs $8,000 – $20,000, window replacement $4,500 – $15,000, and an ADU construction project $90,000 – $220,000 depending on whether you go site-built or prefab through partners like Abodu and Boxabl. The biggest price driver is material choice: a KraftMaid island kitchen with Cambria counters lands around double what a Quikrete-and-stock-cabinet version costs.
What affects the price: structural work (moving walls, foundation repairs), permit complexity in older homes, and the number of trades needed. The best way to avoid overpaying is to consolidate scope, which is exactly what we do. A single GC bid for roof-plus-windows-plus-siding is cheaper than three specialty bids because the schedule overlap gets eliminated. Every Toolbox Contractors estimate is line-itemed, includes material allowances, and shows our markup openly. Call (855) 382-3257 for a free estimate on your specific project, and we’ll give you numbers you can actually compare.

Frequently Asked Questions About General Contractor in San Bernardino
A general contractor is a licensed professional who manages and executes construction projects from permits to final inspection. In California, a GC with a B license can perform or supervise more than two unrelated trades on the same project. That’s the distinction from a trade-specific contractor, and it’s the license Toolbox Contractors holds in San Bernardino.
If your project needs a plumber, a framer, and an electrician, a general contractor coordinates all three, schedules the work, and carries the liability. That’s the core value of hiring a GC instead of running five separate bids.
A small bathroom remodel typically takes 3 – 5 weeks once permits are approved. A full kitchen remodel runs 6 – 10 weeks. A roof replacement is 3 – 5 days of actual work, while a home addition or ADU can take 4 – 8 months depending on the scope and prefab versus site-built choice.
Permit approval with the City of San Bernardino adds 1 – 3 weeks on average, and we factor that into the schedule before we give you a start date. Call (855) 382-3257 and we’ll give you a realistic timeline for your specific project.
Most San Bernardino projects fall between $9,000 and $45,000 for remodels, with larger additions and ADUs running up to $220,000. Kitchen remodels average $14,000 – $45,000, bathrooms $9,000 – $28,000, and roof replacements $8,000 – $20,000 in this market. The cost depends on material grade, structural changes, and square footage.
Our estimates are line-itemed and free. We’ll show you where the money goes, including our markup, so you know exactly what you’re paying for. Call (855) 382-3257 for a precise quote.
Yes. We install PGT impact windows and GAF roofing systems as certified installers, which means the manufacturer’s warranty is backed by our credentialing, not just a verbal claim. We also install Tamko, Boral, and Owens Corning roofing systems regularly.
If you already have a specific brand in mind, tell us during the estimate and we’ll spec it. If you don’t, we’ll recommend what holds up best in San Bernardino’s summer heat and wind patterns.
For roof leaks, storm damage, and urgent structural issues, call us at (855) 382-3257 and we’ll assess the situation right away. We prioritize active leaks and safety issues over scheduled remodels. For non-urgent work, our standard scheduling applies.
If the roof is actively leaking during rain, we’ll get tarps up and a repair scheduled quickly, then quote the permanent fix. Don’t wait for the water to reach the drywall.
We provide a written workmanship warranty on every project, with terms spelled out in your contract before work begins. Material warranties run separately through each manufacturer, and as certified installers for GAF, PGT, and other brands, those warranties are fully valid when we install them.
If anything fails due to our workmanship, we fix it. That’s the standard Norm Castellano has held Toolbox Contractors to in San Bernardino, and it’s not changing.
Make a list of the specific problems you’re trying to solve, not just “remodel the kitchen.” If you have inspiration photos, pull them up. Clear access to the rooms we’ll be measuring, including the garage if you’re considering a conversion. Know your rough budget range so we can steer you toward materials that fit.
Don’t demo anything before we arrive. We need to see the existing conditions to quote accurately, and a premature tear-out can trigger code requirements you didn’t know existed. Call (855) 382-3257 to schedule your free estimate.
