Fast, Reliable Home Remodeling Across Orange
A full kitchen remodel in Orange typically runs $14,000 to $45,000, while a bathroom lands between $9,000 and $28,000. What actually moves those numbers is what’s hiding behind the walls of this city’s housing stock, which splits sharply between century-old Craftsman homes in the Old Towne district and mid-century tract houses in the newer ZIPs. At Square One Builders, we’ve worked both, and we know the difference before we open the first wall. Call (877) 688-9930 to schedule a walkthrough and we’ll give you a straight answer on what your remodel will cost, not a vague range designed to get a signature.
Why Square One Builders Is Orange’s Preferred Home Remodeling Company
Orange homeowners hire us for one reason: we’re a full-scope general contractor, not a specialty shop trying to coordinate three subs from different companies. One contractor, every system. From structural framing to cabinetry, windows to roofing, plumbing fixtures to hardscaping, it’s our crew and our accountability through the whole job. Brent Calloway started this company on that principle, and it’s the reason we get called back for second and third projects in the same households.
We know the city’s design review process in Old Towne Orange cold. That’s not a marketing line, it’s a working reality. When you’re opening walls in a 1918 Craftsman near the Plaza, you need a contractor who has already sat through multiple historic review cycles and knows which changes trigger review and which don’t. We have. Our estimates for Orange jobs include the permitting and review timeline as a line item, because pretending it doesn’t exist is how remodels stall at rough-in and homeowners get stuck paying carrying costs on a torn-apart house.
We also stock and source materials from 50+ brands across every system, including CertainTeed and Owens Corning roofing, so Orange customers aren’t waiting on supply-chain gaps when a project hits the framing stage. Your remodel, fully managed, from the ground up.

Home Remodeling Companies in Orange
Home Remodeling Companies in Orange fall into two camps: those who understand the Old Towne Orange Historic District’s design review rules and those who don’t. The difference shows up as a stopped inspection, a failed permit, or a remodel that stalls at the framing stage because somebody didn’t file the design-review paperwork before demo day. The job here isn’t just demolition and rebuild. It’s knowing which wall openings, window swaps, and rear additions trigger city review, and building that timeline into the contract and draw schedule before the first hammer swings.
Historic District Remodeling
In the pre-1930s Craftsman and Victorian homes around the Plaza, almost every opening triggers some level of historic design review. We handle the documentation, the submittals, and the Mills Act-eligible paperwork that preserves property-tax incentives while keeping the project moving. The materials have to match or sympathetically replicate period detailing. We spec that deliberately, not as an afterthought.
Tract Home Remodeling
A few blocks away in the postwar tracts and Chapman University-area housing, the same kitchen wall opening usually needs no historic review at all. Those jobs move faster and center on modern systems: new cabinetry, flooring, windows, and ADUs. We price and schedule them accordingly, without the review timeline baked in.
Whole House Remodel in Orange
A Whole House Remodel in Orange is where our single-contract model matters most. When you’re opening every room, the interaction between electrical, plumbing, framing, roofing, and exterior systems is where loose coordination falls apart. A home addition typically runs $45,000 to $130,000, and a whole-home scope often layers that with kitchen and bath work. Our job is to sequence it so you’re not redoing work, paying for re-inspections, or living through avoidable delays.
Structural and System Work
Opening an older Orange home turns up what the last remodel buried. Knob-and-tube wiring spliced into newer romex. A notched load-bearing header. Failed waterproofing under a mid-century slab. We inspect for these before we quote, and we write allowances into the contract so they’re priced and approved in writing before we touch the rough-in. No surprise change orders handed to you verbally at 7 a.m.
Finishing the Scope
Once the structural and systems work passes inspection, we handle cabinetry, countertops, flooring, windows, doors, and exterior trim under the same contract. There is no point where we hand you a list and tell you to find a cabinet guy. The finish schedule is our responsibility, down to the last piece of hardware.
Trusted Brands We Service in Orange
We spec materials from brands Orange homeowners actually recognize, including CertainTeed and Owens Corning roofing systems, plus IKO and Atlas for specific roof profiles common on mid-century tract homes. The brand selection is deliberate: CertainTeed for its lifespan and warranty on flat and low-slope roofs that take winter rain, Owens Corning where attic ventilation and heat management matter on hot Santa Ana afternoons. We spec the right material for your project, not whatever is easiest to source. For Orange customers, that means faster installation and fewer callbacks on materials that have to perform in this specific climate.

AfterCommon Home Remodeling Problems We See in Orange Homes
- Undersized or notched framing in pre-1930s Craftsman homes. These houses were built for different loads than today’s kitchens and baths carry. When a wall opens and we find a header that was notched by an old remodel, it gets priced and approved in writing before we touch the rough-in.
- Knob-and-tube wiring hidden behind plaster. Common in Old Towne Orange, often spliced into romex by a previous homeowner or handyman. A wall opening triggers the code upgrade, and we build that allowance into the estimate from the start.
- Failed waterproofing around mid-century and postwar tract homes in ZIPs like 92865 and 92867. The original waterproofing on some of these slabs and low-slope roofs is decades past its service life. Winter rains expose it, usually through the subfloor or ceiling.
- Santa Ana wind damage to exterior finishes and roofing edges. The hot, dry winds that blow through Orange each fall and spring dry out exterior wood, paint, and roofing faster than coastal OC. We inspect for wind-driven wear before we quote, because it changes the exterior scope.

FAQs About Home Remodeling in Orange
Does opening up a wall in an Old Towne Orange home really change the price that much?
Yes. A pre-1930s Craftsman or Victorian wall opening frequently reveals knob-and-tube wiring, notched or undersized framing, and original plumbing that has to come out. Those are code-triggered upgrades once the wall is open, and they can add $5,000 to $15,000 to a room scope depending on what’s found. That is not a surprise we spring on you. We inspect before we quote, write allowances into the contract, and get written approval on any change before we touch the rough-in. Call (877) 688-9930 for an exact quote on your house.
Will our Old Towne Orange remodel need historic design review?
If you’re making exterior changes, a rear addition, or swapping windows in the Old Towne Orange Historic District, the answer is almost certainly yes. Interior wall openings that don’t change the exterior footprint may not trigger review, but anything visible from the street or changing the building envelope usually does. That review timeline has to be in the draw schedule before demo day, or the job stalls mid-rough-in. We handle the submittals and the Mills Act-eligible documentation as part of our scope.
What do you actually inspect before a whole house remodel in Orange?
We inspect the structural framing, electrical and plumbing systems, roofing, waterproofing, subfloor condition, and exterior envelope before we write a number. In Orange that means checking pre-1930s homes for knob-and-tube and notched headers, and checking mid-century tract homes in ZIPs like 92865 and 92867 for failed slab waterproofing and worn low-slope roofing. The inspection determines the allowances, and the allowances determine the honest quote.
How do permits affect a remodeling timeline in Orange?
Permits add time, and the amount depends on your district. In the postwar tracts, a standard permit might add a week or two to the schedule. In Old Towne Orange, historic design review can add four to eight weeks depending on the scope and the commission calendar. We build that timeline into the contract and the draw schedule, so you’re never paying carrying costs on a torn-apart house while waiting for a review hearing.
Can you handle both an Old Towne historic rehab and a tract-home remodel in Orange?
Yes. We’re a full-scope general contractor, and Orange’s two-track market is exactly what we’re built for. One week we’re matching period detailing and pulling historic review paperwork near the Plaza, the next we’re sequencing a tract home remodel and ADU a few blocks away. The same crew, the same contract model, the same inspection-first pricing discipline. Call (877) 688-9930 and tell us which Orange you live in. We’ll tell you what it’s going to take.
