Trusted Home Renovation for San Bernardino Homeowners
Home Renovation in San Bernardino means working with a contractor who understands this city’s specific housing stock. Homes here run from 1940s bungalows near downtown to newer tract builds up toward North Park and Verdemont. Each era brings its own surprises when you open a wall. Toolbox Contractors is a licensed general contractor, and Norm Castellano leads a team that handles the full scope of a renovation: the kitchen, the roof, the windows, the fence, the ADU out back. One contract, one point of accountability. If you’re planning work on your San Bernardino home, call (855) 382-3257 to talk through your project and get a free estimate.
Home Renovation Contractors
Home Renovation Contractors are the general contractors who pull permits, schedule the trades, and carry the liability when you’re changing the structure or systems of your house. You need one the moment your project involves plumbing rough-ins, electrical changes, or anything load-bearing. Toolbox Contractors fills that role for San Bernardino properties, with pricing that tracks the scope: a kitchen remodel runs $14,000 to $45,000, a bathroom remodel $9,000 to $28,000, and a full home addition starts around $45,000. We carry home renovation work from initial walkthrough to final inspection.
Single Point of Accountability
Most renovation horror stories start with a homeowner trying to coordinate a plumber, an electrician, and a cabinet installer who never talk to each other. We remove that variable. Toolbox Contractors runs the entire job under one license and one schedule.
Material Knowledge That Shows Up in the Work
We can talk through why a PGT impact window makes sense for a house backing up to the foothills, or why a PGT or CGI window holds up better when the Santa Ana winds kick through the Cajon Pass. That product-level knowledge is what you’re paying a contractor to have.
Styles & brands we work with







Home Renovators
Home Renovators are the people physically executing the work, from demolition day to the final punch list. You need them when a project is too complex or too dangerous to DIY, which covers most work beyond paint and trim. Toolbox Contractors handles our Home Renovation in Muscoy and across San Bernardino County, from small bathroom remodels at $5,000 to $12,000 up to whole house renovations that exceed six figures. Norm Castellano’s crews have opened enough walls in this city to know what’s behind them.
Brand-Level Installation Standards
A renovation succeeds or fails in the details: how the shower pan is sloped, how the cabinet boxes are shimmed, how the countertop overhang is supported. We install to manufacturer spec so warranties actually apply when you need them.
Interior-to-Exterior Scope
Strange as it sounds, most renovation firms won’t touch a fence or a roof. We do. That means seal and flashing work done by the same team that built your kitchen, which matters when one mistake floods the other.
Home Improvement Contractors
Home Improvement Contractors cover the mid-size projects that improve a home without a full gut: a tub-to-shower conversion, a paver patio, an impact window swap. You need one when the project requires a permit or a licensed trade. Toolbox Contractors handles these jobs across San Bernardino, with pricing calibrated to your market: a shower replacement runs $3,000 to $8,500, a paver patio $3,500 to $11,000, and a vinyl fence $3,500 to $9,000. Compare those numbers to any other local bid.
Defined Scope, Fixed Price
We write line-item quotes that define what’s included before work starts. No change orders because someone “forgot” to mention the dumpster fee. No surprises at invoice time.
Materials From Brands You Already Know
We install Delta and American Standard fixtures when budget matters, Grohe and Toto when you want to step up. Same with countertops: Caesarstone and Silestone alongside more accessible quartz brands. You choose the tier; we handle installation.
Home Renovation Companies
Home Renovation Companies range from single-trade specialists to full-scope general contractors, and the difference shows up the moment your project touches a second trade. You need the latter when you’re doing a kitchen-plus-roof or a bathroom-plus-window job. That’s where Toolbox Contractors operates, with San Bernardino pricing for cabinet installation between $4,000 and $13,000, countertop installation between $2,000 and $6,500, and full home renovation work that’s quoted per project. We’re one of the few Home Renovation in Colton companies also serving San Bernardino with full-scope ADU capabilities.
What One Company Handles Here
A full building envelope: James Hardie siding, PGT or CGI windows, GAF, CertainTeed, or Owens Corning roofs. A full interior: KraftMaid and Wellborn cabinets, Cambria countertops, Kohler fixtures. An ADU: Abodu, Dvele, or Plant Prefab. That breadth is rare.
Built Around How You Actually Live
If backyard housing is in your future, we build for it. ADU construction in San Bernardino runs $90,000 to $220,000 depending on whether you go prefab or site-built. Few renovation companies can even offer that conversation.
Renovation Contractors
Renovation Contractors are licensed general contractors who specialize in improving existing homes rather than building from scratch. You need one when your project involves structural changes, a new roofline, or moving mechanical systems. Toolbox Contractors fills that role in San Bernardino, and our pricing reflects the local market: roofing replacement between $8,000 and $20,000, window replacement $4,500 to $15,000, and complete home additions starting at $45,000. We also serve Home Renovation in Muscoy from the same dispatch.
Roof-to-Foundation Capability
We are credentialed to install GAF, CertainTeed, and Owens Corning roofing systems, which matters because those manufacturers only back warranties through certified installers. That’s leverage you can verify before you sign.
Foothill-Specific Construction Sense
Homes in the foothills above San Bernardino and in Highland deal with drainage and wind differently than homes in the flatlands. We spec materials accordingly: Tamko or Boral roofing for heat exposure, PGT windows for wind-driven debris. Vocabulary that translates to fewer leaks.
Whole House Renovation
Whole House Renovation means touching every major system in a home, usually in phases, with the goal of bringing an older property to modern standard. You need it when deferred maintenance has stacked up: the roof, the windows, the kitchen, the bathrooms all need work in the same decade. A whole house renovation in San Bernardino typically runs from $100,000 to $300,000 depending on square footage and material choices. Toolbox Contractors has the full scope to handle it without farming work out.
Phasing Without Losing Momentum
A full renovation doesn’t always happen all at once. We sequence the work so you’re never living without a kitchen and a bathroom at the same time. Roof first, then envelope, then interior.
Retrofit Reality Checks
Older San Bernardino homes have character and problems: knob-and-tube wiring, cast-iron drain stacks, undersized headers. We cost those realities into the estimate instead of discovering them at demolition, which is how fixed-price renovation should work.
Brands We Service
We install Tamko and Boral roofing systems on homes throughout San Bernardino County. Tamko’s laminated shingles handle the San Bernardino heat well, and Boral’s tile profiles fit the Spanish-style architecture common in older neighborhoods here. Both brands hold up when installed to spec, and we follow the manufacturer’s nailing pattern and ventilation requirements line by line.
For windows and doors, we work extensively with PGT and CGI impact products. PGT’s WinGuard line is a common choice for homes in the foothills or anywhere wind-borne debris is a concern. CGI builds heavy-duty impact windows and doors that meet stricter ASTM standards, which matters if you’re renovating a home with larger glazing areas. Whether you have one of these brands or any other make, we can help you match the replacement product to the existing architecture.

- Roof granules in the gutters. If your gutters are collecting asphalt granules after rain, your shingles are losing their protective layer. In San Bernardino’s sun, a roof in that condition fails faster than in cooler climates. A roof repair runs $400 to $1,800 before the problem spreads into decking and insulation.
- Windows that fog or won’t seal. Failed seals show up as condensation between panes or drafts you can feel on windy days. Those windows are no longer insulating, and you’re paying for that heat loss every month. Replacement runs $4,500 to $15,000, and delaying it just adds utility costs.
- Spongy spots in a bathroom floor. A soft floor near the tub or toilet means water has been getting where it shouldn’t, often for months. By the time you feel it, the subfloor is compromised. A small bathroom remodel at $5,000 to $12,000 fixes the leak and the damage at once.
- Fence posts leaning at the property line. When posts tilt, the footer wasn’t deep enough or drainage is pooling at the base. A leaning fence becomes a downed fence after a good storm. Vinyl fence installation in San Bernardino runs $3,500 to $9,000, and doing it before a section falls saves the headache of a neighbor dispute.
- Cracks wider than a quarter inch in drywall. Small hairline cracks are cosmetic. Wide cracks, especially around door frames, can mean settlement or a shifting foundation. Get a structural assessment before you paint over something that’s still moving.
Our Process, Step by Step
- 1
Walkthrough and scope review. We walk the property with you and talk through what you want to change, what’s working, and what can’t be moved without structural work. You’ll see us take notes on drainage, electrical panel location, and access points. That discipline shows up in pricing later.
- 2
Written line-item estimate. You get a quote that breaks out material costs, labor, permits, and disposal. No allowances unless you want allowances. If you want Caesarstone instead of a basic quartz, the line item changes and nothing else surprises you.
- 3
Permit application and scheduling. We pull permits for the work that requires them in San Bernardino. If the project needs an inspection, it gets inspected. We don’t ask you to accept unpermitted work as a cost-saving measure.
- 4
Construction with weekly updates. You’ll know what happened that week and what’s happening next. If we find something unexpected behind a wall, you get a photo and a call before we touch it, not a change order after the drywall is up.
- 5
Final walkthrough and closeout. We walk the finished work with you and create a punch list for anything that isn’t right. The job isn’t done until that list is cleared and you’re satisfied with the fit, finish, and function of everything we touched.
How Much Does Home Renovation Cost in San Bernardino?
A kitchen remodel in San Bernardino typically runs $14,000 to $45,000 depending on whether you’re refacing cabinets or gutting the room. A small kitchen remodel runs $9,000 to $20,000. Bathroom work follows a similar spread: $9,000 to $28,000 for a full remodel, $5,000 to $12,000 for a small one. At the high end, a home addition starts at $45,000 and an ADU runs $90,000 to $220,000. Those are your market numbers, and any San Bernardino contractor bidding far below them is cutting something.
What affects the price most is scope creep and hidden conditions. A 1940s bungalow near downtown San Bernardino is going to have surprises the moment the drywall comes down: outdated wiring, cast iron drains, undersized joists. A 1990s tract home in North Park is more predictable. The second factor is material tier. KraftMaid cabinets cost more than a stock line, and PGT impact windows cost more than builder-grade. We price both tiers honestly and let you choose where to spend. To avoid overpaying, get everything in writing and never accept an estimate that says “allowance” without a defined cap. Every free estimate from Toolbox Contractors includes a walkthrough, a line-item breakdown, and a fixed price you can compare against anyone else in the area.

Frequently Asked Questions About Home Renovation in San Bernardino
Home renovation is the process of updating, repairing, or changing the structure and systems of an existing home, from cosmetic updates like new cabinets to structural work like a room addition. Unlike new construction, renovation works within and around existing framing, which requires a contractor who can diagnose what’s behind the walls. In San Bernardino and nearby Loma Linda, that often means dealing with older construction methods and materials. Call (855) 382-3257 if you’re not sure whether your project counts as renovation or repair.
A small bathroom remodel typically takes 2 to 3 weeks, a kitchen 4 to 8 weeks, and a whole house renovation 3 to 6 months depending on scope and permit review times in San Bernardino. The schedule depends more on inspection timing and material lead times than on how many people are on site. We give you a written schedule with your estimate so you know what to expect.
Most renovation projects in San Bernardino fall between $9,000 for a small bathroom and $220,000 for an ADU, with kitchens at $14,000 to $45,000 and full home additions at $45,000 to $130,000. Your exact number depends on scope, material choices, and the condition of what’s behind your walls. Call (855) 382-3257 for an exact quote; estimates are free and have no obligation attached.
Yes. We install and service PGT and CGI impact windows in San Bernardino, and we can match existing window styles when you’re renovating part of a home. If your home already has PGT or CGI products, we can assess whether a repair or full replacement makes more sense. Call (855) 382-3257 to schedule a walkthrough.
For active leaks, storm damage, or safety hazards, call (855) 382-3257 and we’ll get a crew out as fast as possible. Emergency work is prioritized separately from scheduled renovations, and we’ll tell you honestly when we can arrive. For non-emergency work, we’ll schedule the soonest available appointment.
Workmanship is backed by our own guarantee, and manufacturer warranties apply to the materials we install: GAF, CertainTeed, Owens Corning, PGT, Boral, and others all have their own terms. We install to the manufacturer’s specification so those warranties are actually valid when you need to make a claim. Ask us about specific product warranties during your estimate.
Clear the work area of personal belongings, decide where you’ll set up a temporary kitchen or bathroom if yours is being renovated, and take photos of the existing condition before work starts. If you have pets, plan where they’ll stay during noisy phases. We’ll walk you through a preparation checklist specific to your project before demo day.
