Fast, Reliable General Contractor Across Antioch
When an Antioch homeowner starts planning a kitchen remodel, room addition, or whole-home renovation, the first question is usually the same: what will this actually cost, and who am I letting through the door? Mason Remodeling answers both before the first tool is unpacked. We deliver a written price on every project, and we send you the name and photo of every crew member before they arrive. If you’re planning construction work in Antioch, call (803) 680-2547 and we’ll walk the job with you, scope it honestly, and put a fixed number in writing.
Construction work in Antioch covers a broader range of housing eras than almost anywhere else in East Contra Costa County. That matters because the right scope for a 1960s ranch in Delta Fair is not the right scope for a 1910 bungalow near downtown. Our General Contractor team plans for the house we’re actually standing in, not the house a generic estimate assumes.
Why Mason Remodeling Is Antioch’s Preferred General Contractor Company
Mason Remodeling has been part of the Threshold Group family since 2004, and our Antioch customers keep calling us back because we do two things consistently: we scope work honestly on the front end, and we stand behind it when it’s done. Homeowners in Antioch want to know who is coming, what the job will cost, and what happens if something goes wrong. We answer all three questions on the first visit.
Every crew member who works in Antioch goes through the Threshold Standard. That means each technician is background-checked, identity-verified, arrives in a clean marked uniform, shows a photo ID badge at the door, and is introduced to you by name and photo before the visit. If you’re home alone, or you have young children, or you’re an older adult who opens the door carefully, that matters. You’ll know exactly who to expect before you unlock the deadbolt.
We also hold a written guarantee on every completed project, with coverage terms stated plainly. Our 365-Day Done Right Promise applies across general contracting, bathroom remodeling, and whole-home remodels. If the work is not right within a year of completion, we make it right at no cost to you. A live person answers our phone around the clock, every day of the year, including weekends and holidays. No call trees, no leaving a message and hoping.
Styles & brands we work with
Licensed General Contractor in Antioch
A Licensed General Contractor in Antioch is the person who holds the state contractor’s license that covers your project, pulls the permits, coordinates the trades, and carries the responsibility for code compliance from rough-in to final inspection. Mason Remodeling is led by Isaac Pruett, and every Antioch project runs through that same standard. When a remodel touches structure, plumbing, or electrical, Antioch’s building department requires permits, and the work has to be sequenced so inspections happen before anything gets covered up.
What the Work Actually Involves
Most Antioch remodels start with demolition, then move into rough-in for plumbing, electrical, and framing changes. After that comes the first inspection, and only then do the walls get closed. Counters, cabinets, tile, and fixtures go in last. The sequence matters because an inspection failure at rough-in can reset the whole calendar.
When Antioch Homeowners Need This
You need a licensed general contractor when the job spans more than one trade: a kitchen remodel that moves plumbing, a bathroom remodel that relocates a shower drain, a room addition, or an ADU. A kitchen remodel in Antioch typically runs $14,000 – $45,000, and a bathroom remodel runs $9,000 – $28,000. If the job involves moving walls, adding square footage, or touching the service panel, the license is not optional.
Residential General Contractor in Antioch
A Residential General Contractor in Antioch manages homeowner-facing remodeling projects end to end: scope, permit drawings, scheduling, inspections, and the final walkthrough. Not every project needs the same license class, but every project needs someone who knows Antioch’s housing stock. That’s the part a generic contractor misses, and it’s the part that costs Antioch homeowners money when it’s missed.
Scoping for Older Antioch Homes
Antioch’s housing stock spans early-1900s downtown bungalows, 1960s – 70s ranch tracts, and newer hillside subdivisions. A general contractor here must scope a wall-opening or window job differently depending on whether it hits original knob-and-tube wiring, aluminum branch wiring, or stucco over wood lath. That mix, not one dominant trait, means the same kitchen or bath scope can require a different trade sequence by block.
Flat-Lot Thinking Costs Money Here
Treating Antioch’s hillside and delta-adjacent lots as standard flat-lot builds is a mistake. Drainage, grading, and foundation repair can add scope before framing even starts. We price for the lot we’re standing on, not the one a template estimate assumes.
Trusted Brands We Service in Antioch
We don’t ask Antioch homeowners to choose between good products and a contractor who can actually get them. Our specification-grade material partnerships cover cabinetry from KraftMaid and Wellborn, surfaces from Cambria and Silestone, and fixtures from Kohler, Moen, and Toto. Founded in 2004, Mason Remodeling has spent two decades building relationships with these manufacturers, which means our Antioch customers get vetted, professional-grade materials in one place. We also service projects that involve factory-built ADU products from brands like Abodu, Cover, Dvele, and Mighty Buildings. When a homeowner in Antioch wants a factory-built accessory dwelling unit, we can handle the site work, utilities, and foundation scope that those projects require.
Common General Contractor Problems We See in Antioch Homes
- Plaster-on-lath where drywall was assumed: Downtown Antioch bungalows from the early 1900s often have plaster walls over wood lath, not modern drywall. Scoping a kitchen or bath remodel on the assumption of conventional 2×4 framing with drywall leads to a rude discovery on demo day, and a change order the homeowner never saw coming.
- Unpermitted past work hiding behind walls: Many older Antioch homes have had electrical or plumbing work done over the decades without permits. When we open a wall and find it, the repair has to be documented and brought to code before we can close up. That’s a real cost, and a contractor who doesn’t flag it up front is not doing you a favor.
- Low allowances for rough-in plumbing and electrical: Mid-century ranch tracts in neighborhoods like Delta Fair often have original 3-wire circuits and galvanized supply lines. If the allowances for plumbing and electrical rough-in are set too low, the first inspection sign-off forces a change order well beyond the original draw schedule. We set allowances honestly, because a written price is only worth something if it holds.
- Hillside drainage and foundation scope: Antioch’s newer subdivisions climb the hills on the south and west sides of town, and the lots don’t always shed water the way flat lots do. A room addition or ADU on a sloped lot can require additional grading, drainage, or foundation work before framing starts. We look at the lot, not just the footprint.
We took on a 1964 ranch in Antioch’s Delta Fair area where the homeowner wanted a kitchen remodel. When we opened the wall, we found the range circuit was old 3-wire without a ground. We pulled permits, had the rough-in inspected before the walls closed, and documented the electrical correction as a change order. The job finished with KraftMaid cabinets, Cambria counters, and a final punch list sign-off. That’s how a scoped job should go: discoveries get documented, priced, and approved, not buried in the final bill.

FAQs About General Contractor in Antioch
Yes, if the project touches plumbing, electrical, or structural framing, Antioch’s building department requires permits. That covers most kitchen and bathroom remodels. Cosmetic work like painting or replacing a vanity without moving plumbing may not need one. Call (803) 680-2547 and we’ll tell you what applies to your specific project.
A typical Antioch kitchen remodel runs 8 to 14 weeks from permit submission to final punch list. Projects on older homes with plaster walls or unpermitted past work can add 2 to 4 weeks. We’ll give you a written schedule with your written price, and we’ll update it when inspections are scheduled.
The most common change orders in Antioch come from discoveries behind walls: knob-and-tube wiring in a downtown bungalow, unpermitted plumbing in a mid-century ranch, or drainage problems on a hillside lot. Our approach is to document every discovery, price it, and get your written approval before proceeding. Nobody gets surprised on the final bill. Call (803) 680-2547 for an exact quote, and we’ll show you how our change order process works.
Yes. ADU construction and garage conversions in Antioch involve foundation work, utilities, and multiple inspections. A licensed general contractor manages the permit drawings, the trade sequencing, and the inspections. ADU construction in Antioch typically runs $90,000 – $220,000, and a garage conversion runs $30,000 – $80,000.
Your written estimate should list every line item, including demolition, rough-in plumbing and electrical, finish materials, permit fees, and the schedule. It should also state the process for change orders and the terms of the workmanship warranty. At Mason Remodeling, a written price is delivered on every project before any work begins. It’s standard, never an upgrade or a favor.
