Fast, Reliable General Contractor Across Orange
When you’re planning a kitchen gut, a bathroom overhaul, or a full ADU build in Orange, you need one contractor who can carry the whole project from the first permit submittal to the final walkthrough. That’s what we do. Toolbox Contractors is a licensed General Contractor serving Orange homes from Old Towne’s Craftsman bungalows to the acreage parcels off Santiago Canyon Road. We work inside and out: cabinets, countertops, roofs, windows, fencing, hardscape, and prefab ADUs, all under one contract. Call Norm Castellano’s team at (855) 382-3257 to get a free written estimate for your Orange project.
Why Toolbox Contractors Is Orange’s Preferred General Contractor Company
Orange homeowners keep calling us back because we speak the language of this city’s housing stock. A 1910 Craftsman in the Plaza District is not the same job as a 1960s ranch in the tracts near Villa Park. If you’re inside the Historic Preservation overlay, we know what triggers design review. If your piers are original redwood and your walls are lathe-and-plaster, we’ve already priced that demo and shoring before we hand you a number. No blank stares at a century-old foundation. No change order when the inspector flags knob-and-tube. We plan for what Orange homes actually throw at a contractor, and we price it on the front end.
Orange customers routinely mention the same thing on their callbacks and reviews: the bid matched the final invoice. That matters here because remodels in the older districts have a way of surfacing surprises in the rough-in phase. When we find a dry-rotted sill plate under a Plaza bungalow, the number we discussed already anticipated that risk. That’s not luck. That’s local experience.
We also work the county side of Orange, which most city contractors won’t touch. Unincorporated parcels around Orange fall under county permitting, not city of Orange jurisdiction, and we’ve built enough out there to know how that changes the project schedule and the draw inspections. One General Contractor in Orange for both historic city lots and open county acreage: that’s the point of hiring us.
Styles & brands we work with







Remodeling Contractor in Orange
Remodeling Contractor work in Orange usually means taking an older home down to the studs in some rooms while preserving what’s still structurally sound, and that’s a much more careful sequence than new construction. On the west side around Old Towne, a kitchen or bath remodel often runs $14,000 to $45,000 for a full kitchen and $9,000 to $28,000 for a bath, depending on whether we’re rerouting plumbing, opening load-bearing walls, or working around original framing. In the 1950s tracts east toward the 55, remodels are cleaner, but we still see galvanized supply lines and undersized panels that need upgrading before new fixtures go in.
Full-Scope Interior Work
One crew can demo, frame, drywall, tile, set cabinets, and trim out. You don’t call a plumber and a cabinet installer separately. We handle the rough-in, the Schluter shower system, the KraftMaid or Wellborn cabinet install, and the Cambria or Caesarstone countertops, then we close walls and paint. One schedule, one accountable group of people.
Exterior and Envelope Upgrades
The same contract can cover a GAF roof, PGT windows, and James Hardie siding on the same house. Orange’s Santa Ana wind season in the fall makes this sequencing matter: we don’t tear off a roof in October and leave a house exposed for a window order to arrive. We order materials before demo starts, and we schedule exterior work for the shoulder seasons when Orange’s weather is most predictable.
Licensed General Contractor in Orange
Licensed General Contractor work in Orange means one entity responsible for every trade, every permit, and every inspection on your project. We pull permits with the city of Orange for work inside city limits, and we pull county permits for parcels in the unincorporated pockets that carry an Orange mailing address, which is a distinction that trips up a lot of homeowners and some contractors. A full home addition in Orange runs $45,000 to $130,000, and a detached ADU runs $90,000 to $220,000. A garage conversion is $30,000 to $80,000. Those ranges assume we’re handling grading, drainage, and utility runs, not just framing and finish.
Permit Management
We handle the submittals, the plan checks, and the inspector walks. On county acreage, that includes septic and well setback verification, which can change a building pad location by ten feet or more. We flag that before you pour concrete, not after the inspector red-tags the form boards.
Foundation and Subfloor Repairs
Orange’s pre-1920s homes sit on redwood piers that were installed a century ago. Many of them have rotted. We sister joists, replace piers, and level floors before we ever set a cabinet or tile a shower pan. If you’re remodeling a Plaza-area home, budget for this. We’ll tell you what we see in the crawlspace on the first walkthrough.
Trusted Brands We Service in Orange
We install materials you can actually verify, not whatever’s on the distributor’s clearance rack. On Orange jobs, you’ll see Quikrete and Sakrete mixes in our concrete and paver base work. For ADU builds, we work with Abodu on prefab options that get you a permitted structure faster than stick-built, and we handle the site work, foundation, utilities, and inspections that Abodu requires. When we need retaining wall or paver materials, Oldcastle product shows up on our Orange job sites regularly. We carry or source local inventory so Orange projects don’t stall waiting on a truck from Riverside.

AfterCommon General Contractor Problems We See in Orange Homes
- Historic review surprises. Exterior changes visible from the street in the Old Towne Plaza Historic District can trigger design review before the city issues permits. We submit the drawings and materials schedule the first time so the review doesn’t bounce.
- Septic and well setbacks on acreage. On unincorporated parcels off Santiago Canyon Road or Chapman, septic leach field and well locations can force a building pad to shift. We verify setbacks in the bid phase, not the rough-in phase.
- Long material hauls and access problems. A paver or concrete truck on a rural unpaved driveway in Orange’s eastern hills is a real logistics issue. We scope access improvements, like temporary culverts or stone pads, before delivery day.
- Original wiring and plumbing fails. Knob-and-tube wiring and galvanized supply lines are common in Orange’s 1900-1920s housing. You don’t want a new kitchen on a 60-amp service. We inspect and upgrade as part of the remodel scope.
Pricing for General Contractor in Orange, CA
Orange pricing reflects two very different project profiles. A city-lot remodel near the Plaza works within tight access and historic constraints, while an acreage parcel east of the 241 involves grading, drainage, septic and well verification, and possibly a long material haul. That’s why our Orange estimates are line-itemed, not lump-summed. Below are the current ranges we quote for the major scopes.
| Project | Orange, CA Price Range |
|---|---|
| ADU Construction | $90,000 – $220,000 |
| Home Addition | $45,000 – $130,000 |

FAQs About General Contractor in Orange
County permits, not city of Orange permits. Unincorporated parcels with an Orange mailing address fall under Orange County building jurisdiction. We file with the county, schedule county inspectors, and handle the septic and well setback verification they require before we pour the foundation. Call (855) 382-3257 and we’ll confirm which jurisdiction your parcel falls under before we quote.
They can add anywhere from a few thousand to over ten thousand dollars to the site work. A leach field or well that sits too close to the proposed structure forces us to relocate the build pad, run longer utility trenches, or install an engineered septic redesign. We pull the county records and take field measurements in the bid phase so that cost appears in your estimate, not in a change order after the rough-in. Call (855) 382-3257 for a site-specific number.
On a sloped or unpaved Orange parcel, we establish the pad elevation, cut or fill as needed, install a drainage swale that directs stormwater away from the foundation, and compact the soil before we form any footings. On a recent detached ADU build off East Santiago Canyon Road, we regraded the lot and cut a drainage swale that keeps runoff from pooling at the slab. Expect grading and drainage to add $5,000 to $20,000 depending on slope and soil. Call (855) 382-3257 for a free site walk.
Yes. We prepare the drawings, materials schedule, and exterior finish samples the city’s design review board wants to see, and we attend the review if needed. Exterior changes visible from the street, including windows, roofing material, and porch details, are the typical triggers. Interior remodels usually clear without design review unless the home is on the city’s historic register. Call (855) 382-3257 and we’ll tell you if your property falls inside the overlay.
We scope access before we bid. On unpaved or narrow drives, we plan for a temporary culvert, a compacted stone pad for the concrete or paver truck, and a staging area that doesn’t block the road. On the East Santiago Canyon ADU we mentioned, the crew managed a 200-foot material haul over an unpaved driveway and had a temporary culvert installed before the first delivery. That access work is in the estimate up front. Call (855) 382-3257 for a free estimate that includes access, not just construction.
