Fast, Reliable General Contractor Across San Antonio
General contracting in San Antonio means navigating homes built on clay soil that moves. Our General Contractor team handles the full scope of remodeling and construction work here, from kitchen remodels in established neighborhoods to whole-home additions on the north side. When a San Antonio homeowner calls us, the first question is usually about cost, so here’s the honest answer: most full kitchen remodels in this market run $14,000 – $45,000, bathrooms $9,000 – $28,000, and additions $45,000 – $130,000. Call (254) 269-5071 and we’ll walk you through a written line-item quote, not a rough guess.
San Antonio’s housing stock is unlike what you’ll find in Austin or Dallas. Many homes north of Loop 410 and across the west side are post-tension slab construction from the 1970s through the 1990s, which changes how we plan plumbing moves, electrical runs, and even where we place a new kitchen island. You need a contractor who knows what’s under the concrete before anyone swings a hammer. That’s exactly what we do.
Why Mason Remodeling Co San Antonio Is San Antonio’s Preferred General Contractor Company
San Antonio homeowners keep calling us back because we lead with the thing that scares people most about remodeling: what it actually costs once the walls are open. Every project starts with a written price, delivered before any work begins. No verbal estimate that drifts upward. No invoice surprises at the end. That standard has been part of Mason Remodeling since our founding in 2004 as part of the Threshold Group family, and it applies to every San Antonio job we take, from a tub-to-shower conversion to a full garage conversion.
We also take the “who’s coming to my house” question seriously, because most homeowners do. Every crew member who arrives at your door in San Antonio is background-checked, identity-verified, and wearing a clean uniform with a photo ID badge. You receive the technician’s name and photo before the visit. That’s the Threshold Standard, and it’s non-negotiable. Isaac Pruett, who leads Mason Remodeling Co San Antonio, has built the local operation around the same principle: you know exactly who is in your home, and you have their name before they knock.
Reviews from San Antonio customers repeatedly mention two things: the written price held, and the crew was exactly who the office said they’d be. In a market where word-of-mouth drives most remodeling decisions, that matters. We answer the phone with a live person 24 hours a day, every day of the year, including weekends and holidays. If you call our San Antonio office at (254) 269-5071, a human picks up. No call trees.
Styles & brands we work with
Construction Company in San Antonio
A Construction Company in San Antonio has to account for soil movement before it accounts for anything else. Our construction work here spans room additions, structural repairs, and foundation-sensitive interior work. The San Antonio market prices additions between $45,000 and $130,000 depending on square footage, roofline complexity, and what the soil under the slab requires. When we scope a room addition on the north side, we’re checking post-tension cable layouts, drainage patterns, and how the existing slab is performing before we ever finalize a number.
Structural and Addition Work
Room additions in San Antonio rarely start with a clean slate. Most existing homes have settled unevenly, which means the connection point between old slab and new foundation needs an engineer’s eye. We sequence the work so that any soil-related movement is identified first, then priced in writing before concrete is poured. On a recent pier-and-beam project in Alamo Heights, our crew opened a wall to relocate a kitchen sink and found the rim joist had dropped nearly an inch after a dry summer, leaving the subfloor sagging and the drain rough-in out of level. We wrote a change order for sistering the joists with pressure-treated lumber, had the inspection sign-off before closing, and still kept the project on the original draw schedule. That’s what a San Antonio contractor is supposed to do: find the problem, price it in writing, and keep moving.
Garage Conversions and Permits
Garage conversions in San Antonio run $30,000 – $80,000, and the permit path matters more than most homeowners expect. Converting unconditioned space to living space triggers insulation requirements, egress upgrades, and often electrical service changes. We pull permits on every project and handle inspections so the work passes the first time. No homeowner should discover after the fact that their converted garage can’t legally be called a bedroom because a window wasn’t sized for egress.
Remodeling Contractor in San Antonio
A Remodeling Contractor in San Antonio is only as good as how they handle what’s behind the drywall. Our remodeling work focuses on the trades that make a home livable: kitchens, bathrooms, whole-home layouts, and the tile, cabinetry, and fixtures that go into them. San Antonio pricing for a kitchen remodel is $14,000 – $45,000; a bathroom remodel runs $9,000 – $28,000. Those ranges reflect what we see in single-family homes across the city, from King William historic properties to far northwest subdivisions.
Kitchen and Bath Remodels
Every kitchen or bathroom remodel in San Antonio is a discovery project. Open a 1970s north-side kitchen and you’re likely to find aluminum wiring that doesn’t meet current code, galvanized supply lines with restricted flow, and cabinets hung on framing that’s been moving with the clay for four decades. We write allowances into every contract for these hidden conditions. When a surprise shows up, the homeowner sees a written change order with a fixed price before we touch anything. That’s not a favor; it’s how our written-price policy works.
For tile and fixtures, we work with specification-grade product lines like Kohler and Moen, and surfaces from Cambria and Silestone. You get vetted, professional-grade materials without having to chase down a supplier yourself. And if the job isn’t right within 365 days of completion, our Done Right Promise means we make it right at no cost to you.
Trusted Brands We Service in San Antonio
San Antonio’s intense UV exposure and flash-drought cycles are hard on roofing and exterior materials. That’s why we stock and install roofing from manufacturers like Atlas and CertainTeed, and hardscape lines like Belgard for pavers and patios. When a San Antonio homeowner needs a roof repair after a hailstorm rips through the northwest corridor, or a driveway replaced after flash-drought soil shifts crack the concrete, we have local access to parts and materials without waiting on a distributor in another city. Fast turnaround for San Antonio customers means we’re not quoting lead times that stretch into the next season.

AfterCommon General Contractor Problems We See in San Antonio Homes
- Post-tension slab surprises. Cutting into a post-tension slab without X-raying the cable layout can cause a catastrophic cable snap during a kitchen or bathroom remodel. We map the cables before any saw cutting, every time.
- Hidden code triggers. Opening walls in a 1970s home almost always reveals outdated wiring or failed waterproofing that a permit inspector will flag. We build allowances into the contract so these aren’t surprise charges after demo.
- Late-summer foundation movement. San Antonio’s expansive clay shrinks during dry spells, and cracks that show up overnight in late August are often the result of weeks of gradual soil contraction. We assess slab movement before any remodel, not after tile is down.
- Heat-timed concrete failures. Exterior work like driveways and patios poured during peak summer heat can crack within months if the soil underneath is shifting from flash-drought conditions. We time and cure exterior concrete work differently in San Antonio than we would in a cooler climate.
Pricing for General Contractor in San Antonio, TX
Here’s what a San Antonio homeowner can expect, based on what we see across the city’s single-family housing stock:
| Project Type | Typical Price Range |
|---|---|
| Kitchen Remodel | $14,000 – $45,000 |

Several factors move the needle in San Antonio specifically. Foundation condition is the biggest one: a home on settled clay may need slab or pier work before a remodel begins, and that’s priced separately. The age of the home matters too. A King William historic home with original framing costs more to remodel than a 1990s north-side house. We give you a written line-item quote for free, so you know the exact number before you decide.

FAQs About General Contractor in San Antonio
Yes, in most cases. When walls are opened on a permitted remodel, the inspector will require current-code compliance for anything exposed, which in a 1970s San Antonio home typically means upgrading aluminum wiring branches, adding GFCI protection, and replacing galvanized piping sections that are no longer code-compliant. We write allowances for these triggers into the contract so you see a realistic number upfront. Call (254) 269-5071 and we’ll explain what your specific house is likely to trigger.
Post-tension slabs contain steel cables under tension, and cutting into a cable can cause it to snap with explosive force. Before any plumbing or electrical relocation in a post-tension San Antonio home, we X-ray the slab to map the cable layout, then design the trenching runs to avoid them entirely. This adds a step to the project but prevents a repair bill that can exceed the cost of the original remodel. We include cable mapping in every slab-cut quote.
Late August is when San Antonio’s clay soil is at its driest after months of summer heat, and clay shrinks as it dries. That shrinkage pulls on the slab, and cracks that were forming slowly underground finally become visible. The right sequence is to have the slab and foundation assessed before any remodel work starts, because laying tile or expanding a footprint on a slab that’s actively moving wastes money. We include that assessment in our scoping process. Call (254) 269-5071 to schedule a walkthrough.
Usually yes. A bathroom remodel in San Antonio that involves changing plumbing fixtures, upgrading electrical, or reconfiguring the shower or vanity typically requires a permit, even if the walls stay put. The city’s permitting process is straightforward, but the inspections are real. We pull the permits and handle the inspections on your behalf so the work is signed off properly and covered by your homeowner’s insurance if anything ever happens downstream.
The realistic approach is a written contract with line-item allowances for known unknowns: outdated wiring, failed waterproofing, settlement-related framing repairs, and post-tension cable mapping. When a surprise is discovered during demo, we document it, price it in a written change order, and get your approval before touching it. That’s the only honest way to remodel an older San Antonio home. Call (254) 269-5071 for a written quote on your project, free.
