Fast, Reliable Home Remodeling Across Tustin
Home remodeling in Tustin means something different depending on which side of the 5 you live on. Old Town bungalows with pier-and-beam floors, Tustin Ranch tract homes with slab foundations, and Tustin Legacy infill with long-span timber framing each demand a very different scope of work. We’re Square One Builders, and we’ve done all three. Our crews are on Tustin job sites every week, and we quote remodels based on the actual house you have, not a generic zip code formula. Call (877) 688-9930 to schedule a free estimate, and we’ll walk your property with you before any numbers are written.
Why Square One Builders Is Tustin’s Preferred Home Remodeling Company
Tustin homeowners call us after they’ve already talked to two or three specialty contractors and realized they’d be managing a roofing crew, a cabinet shop, and a floor installer on their own. That’s the problem we solve. We handle Home Remodeling from structural work to finish carpentry under one contract, with one project lead accountable for the whole thing. Brent Calloway runs our Tustin work personally. He walks every site before we quote, and he’s the one who answers when an inspection question comes up mid-project.
Our Tustin customers tend to be people who’ve owned their homes long enough to know where the weak spots are. They know Old Town homes settle. They know Tustin Ranch roofs see serious UV. They want a contractor who already knows that too, not one who has to learn it on their clock.
Styles & brands we work with
Home Remodeling Contractor in Tustin
A Home Remodeling Contractor in Tustin handles the full renovation of a kitchen, bathroom, addition, or whole-home update, coordinating every trade from demolition through final inspection. The scope on a Tustin job often includes pier-and-beam leveling in the older neighborhoods or stucco repair and roof replacement in the tract communities. A typical kitchen remodel in Tustin runs $14,000 to $45,000, while a home addition starts around $45,000 and can reach $130,000 depending on square footage and foundation conditions.
Foundation and Structural Scope
Before we price cabinets, we check what’s underneath the floor. In Old Town Tustin, that usually means inspecting beams, piers, and termite damage. On Tustin Legacy parcels, it can mean long-span timber framing or slab work tied to the old base’s construction history. We scope structure first, because that’s what keeps a remodel from becoming an emergency mid-project.
Full-Scope Coordination
You don’t hire separate specialists for plumbing, electrical, cabinetry, and roofing. We run all of it. That means one draw schedule, one point of accountability, and no phone calls where the plumber blames the framer. From the ground up, your remodel is fully managed by one team.
Home Remodeling Companies in Tustin
Home Remodeling Companies in Tustin range from one-truck handyman outfits to full-service general contractors, and the difference shows up in how inspections get handled and how material selections get coordinated. A design-build firm might charge a premium for drawings. A specialty cabinet installer can’t touch your foundation. Square One Builders sits in the middle of that market with full GC licensing and a 50-plus brand material portfolio, so the same team that levels your floors also orders your cabinetry and installs your windows. A bathroom remodel in Tustin typically runs $9,000 to $28,000, and a garage conversion lands between $30,000 and $80,000.
Material Sourcing Without the Runaround
We spec from a curated brand list across roofing, cabinetry, countertops, plumbing fixtures, windows, siding, fencing, and hardscaping. Want Cambria on the counters but Silestone on the island? Fine. CertainTeed on the roof instead of Owens Corning? Both are in our supplier network. You get the right material for your project without switching contractors.
Accountability Through Inspection
On Tustin acreage and Legacy parcels, we pull county permits where required and stay on site through inspection sign-off. We don’t close walls until the inspector clears the work. That discipline is why our Tustin clients don’t carry change-order anxiety into the back half of their project.
Trusted Brands We Service in Tustin
We install and service a wide range of nationally recognized brands across Tustin, with local supplier relationships that keep lead times short. For roofing, we work with CertainTeed, Owens Corning, IKO, and Atlas, which means we can match your existing roof profile or upgrade to a higher-tier material without changing contractors. For countertops we carry Cambria and Silestone. For cabinetry, KraftMaid and Wellborn. Our Tustin customers get access to these brands through our supplier network, with ordering handled by us, not left to you to chase down.

AfterCommon Home Remodeling Problems We See in Tustin Homes
- Pier-and-beam rot in Old Town: The 1920s to 1940s bungalows off El Camino Real often have load-bearing beams with decades of slow moisture damage. We open the floor, inspect, and re-level before any finish work starts.
- Knob-and-tube wiring behind 1920s walls: Old Town kitchens and bathrooms frequently still have original wiring. We include electrical re-rough-in in the scope when we see it, not as a surprise change order later.
- UV and dry-rot on Tustin Ranch exteriors: Santa Ana wind season strips stucco and roofing of protective coating fast. Sun-damaged fascia, dry-rotted window trim, and brittle shingle underlayment are routine finds.
- County permitting confusion on acreage: Properties outside city limits but with Tustin addresses often need county building department permits and septic/well setback review. We pull the right permits from the start, so inspection sign-off doesn’t stall the project.

FAQs About Home Remodeling in Tustin
Yes. If the property sits outside Tustin city limits but carries a Tustin postal address, the county building department is the permitting authority, and county rules apply to septic setbacks, well clearances, and grading. We confirm jurisdiction before we quote, so you’re not surprised by a forced change order after the first inspection attempt. Call (877) 688-9930 if you want us to check your parcel.
A pier-and-beam remodel in Old Town costs more than a slab-tract kitchen because we usually level the floor system before cabinetry goes in. That means inspecting joists, replacing rotted beams, and sometimes pouring new piers. It’s not a mystery; it’s a line item. Add roughly a week and a few thousand dollars to the base kitchen range, and we’ll tell you the exact number after we open the floor. Estimates are free.
Yes, and we’ve done it. The septic system’s design capacity becomes the limiting factor, not the lot size. A two-bedroom ADU on a property with an older septic may require a system upgrade, which pushes the total toward the upper end of the $90,000 to $220,000 ADU range. We review septic records early in scoping so the design fits the actual site.
For a Tustin Ranch bathroom with a slab foundation and standard 1980s to 2000s framing, budget $9,000 to $28,000, with the higher end covering a full gut, new shower pan, custom vanity, and higher-tier fixtures from Kohler or Grohe. If you’re keeping the layout and just updating surfaces, the lower end holds. Call (877) 688-9930 and we’ll scope your specific bathroom.
We send a site lead out before we quote to check driveway width, turn radius, and overhead clearance. On long rural driveways with tight turns, a concrete truck or a framing lumber delivery may need a staging plan or a smaller vehicle. We bake that into the draw schedule and the material haul allowance before you sign anything, so it doesn’t blow your timeline later.
