Trusted Construction in San Antonio for Homeowners Who Expect It Done Right
Construction - San Antonio means dealing with heat, shifting clay soil, and building codes written for Texas weather, and that changes how the work should be done. Whether you’re adding square footage, repairing structural damage, or remodeling a kitchen, the difference between a project that holds up and one that fights you for years comes down to discipline: written pricing before work starts, crews who show up inside their window, and a guarantee that stands behind the finished work. Preston Harley leads our construction team in San Antonio, and every job we take on carries the same promise we’ve held since 2010: The Garrison Standard. That means you know the price before we swing a hammer, and the work is backed in writing for a full year. Call (409) 215-3468 to talk through your project.
What Our Construction Service Includes
Construction is a broad word, and in San Antonio it covers everything from a rotted porch beam to a full addition. Here’s what we handle, and how we approach each piece.
Home Additions
Adding a bedroom, a second living area, or extra square footage over a garage changes how your home breathes, how it’s taxed, and how the roofline ties together. In San Antonio, additions also have to account for slab foundations on shifting clay soil, which is why we begin every addition with a structural review before we quote a number. Garrison Partners plans the work so the new space connects cleanly to the existing structure, with permits pulled by the book and the price fixed in writing before concrete is poured. You’ll see the full scope, the materials, and the schedule before you commit, and the finished work is covered by our 365-Day Done Right Promise.
Kitchen and Bath Remodeling
A kitchen or bath remodel in a San Antonio home often means dealing with cast-iron plumbing, older electrical panels, and layouts that were not built for modern fixtures. We handle the full gut and rebuild, and we coordinate the plumbing, electrical, tile, cabinetry, and finish work so you don’t have to chase four different crews. Before any demolition starts, we document the existing plumbing and wiring locations and give you a written price that includes the work we’ll do, not a number that gets adjusted at the door. If you’ve been putting off a remodel because you’ve heard stories about contractors who vanish mid-project, this is where the Garrison Standard matters most.
Structural Repairs
Foundation movement, water damage, and termite issues are all common in the San Antonio area, and a cracked beam or sagging floor is not a cosmetic problem. We assess the condition with a level and a moisture meter, identify whether the root cause is water, soil movement, or an original framing issue, and then give you a written scope for the repair. Doors that stick, drywall cracks that reappear after patching, and floors that slope toward the center of the house are all signs we look for. Garrison Partners repairs the cause, not just the symptom, and we’ll tell you honestly if the fix is small or if it requires deeper work.
Decks, Patios, and Outdoor Structures
San Antonio’s heat, sun, and occasional hard rains are rough on exposed wood, and a deck that sits in full south-facing sun needs different materials than one that’s shaded. We build and repair decks, pergolas, patio covers, and detached workspaces, and we’ll recommend materials rated for the UV load and humidity swings this city sees each year. Every outdoor project gets a written price up front, and we treat the site the way we’d want our own yard treated at the end of the day: swept, stacked, and clean. If the work is a repair on an older structure, we’ll tell you what’s worth saving and what needs to come out before you spend a dollar.
Interior and Exterior Trim, Siding, and Repair Work
Trim rot, siding damage, water intrusion around windows, and drywall repair all fall under the umbrella of construction, and they’re the jobs that keep a home from quietly falling apart. In San Antonio’s humidity swings, caulked joints fail and painted wood peels faster than in drier climates, so we use materials and sealants built for that cycle. We handle the small repairs with the same written-price rule as the big projects: you see the number before work begins, and the work is done to the same Garrison Standard whether it’s a hundred-dollar fix or a full exterior restoration.

Brands We Service for Construction
We work with materials and components from Amarr, Wayne Dalton, Craftsman, and Raynor on projects that involve garage structures, exterior doors, and integrated storage, and we know how each brand’s products behave in San Antonio conditions. Amarr doors, for example, come with specific wind-load ratings that matter in this part of Texas, and we install and repair them according to the manufacturer’s specs rather than guessing at the hardware. Wayne Dalton’s lighter-weight panels and Craftsman’s builder-grade hardware each have their own mounting and adjustment requirements, and we’ve handled enough of them to know where the failure points tend to be after a few San Antonio summers.
Raynor’s higher-end lines show up on newer custom homes around Alamo Heights, Terrell Hills, and Stone Oak, and we know those systems well enough to service them without a learning curve on your dime. Whether you have one of those brands on your home or something else entirely, we can help. The brand matters less to us than the condition of the structure it’s attached to, and we’ll tell you what you actually need rather than selling you a name.
Signs You Need Construction Work Right Now
- Doors that stick or won’t latch. When interior doors start catching on their frames or exterior doors won’t close square, the cause is often foundation movement or framing that has shifted. In San Antonio’s clay soil, this shows up seasonally, and ignoring it lets the underlying movement continue against the framing. Once a door binds, the structure around it is under stress, and that stress doesn’t fix itself.
- Cracks that widen or return after patching. A hairline crack in drywall is normal; a crack that runs diagonally from a corner and returns within months is not. Diagonal cracks around door and window openings are a classic sign of differential settlement. If you’ve patched the same crack twice, the framing behind it is still moving, and the next step is a structural look rather than another coat of mud.
- Spongy or sloping floors. A floor that bounces when you walk across it, or one that visibly slopes toward the middle of a room, is telling you about the joists and beams underneath. San Antonio slab homes see slab issues; pier-and-beam homes see joist rot and settlement. Either one is a structural conversation, and the sooner we look, the less invasive the repair tends to be.
- Water staining on ceilings or walls. A water stain that grows after rain or spreads across a ceiling means a leak somewhere above it, and by the time you see the stain, the water has already been working on the framing. In San Antonio’s hard-rain months, a small roof or flashing leak becomes a mold and rot issue inside a single season. Stains inside the house are a construction repair, not just a paint touch-up.
- Visible rot on exterior trim, siding, or deck boards. Soft wood, peeling paint that reveals dark streaks, and boards that crumble when probed are all signs of moisture damage. San Antonio’s humidity and occasional freezes open up paint and caulk, and once water gets behind trim or siding, it travels. Rotted exterior wood invites insects and lets the damage spread to the framing behind it, so replacing the visible rot early is cheaper than reframing a wall later.
Our Construction Process – Step by Step
- 1
Contact and scheduling. Call (409) 215-3468 and a live person answers; we don’t route you through a voicemail loop or a call center script. We’ll ask about the project, set a visit window that works for your schedule, and tell you who is coming to your door before they arrive. Every member of our San Antonio construction team is background-checked and uniformed, so you know who belongs on your property.
- 2
On-site assessment. We walk the site with you and look at the actual structure. That means a level on floors, a moisture meter on suspect walls, a look at the foundation line, and an honest conversation about what’s urgent and what can wait. We’re not there to sell you; we’re there to diagnose. If the project involves structural questions, we’ll explain what we’re seeing and what it points to before we quote anything.
- 3
Written, fixed-price quote. Before any work starts, you get the scope and the price in writing. That’s not a policy; that’s the Garrison Standard, and it applies to every construction job in San Antonio, from a single beam repair to a full addition. The number we put in writing is the number you pay, and if the project changes, we talk about it and re-paper it before moving forward, never after the invoice is written.
- 4
Scheduled work, done by the book. We arrive inside the window we gave you, protect the work area, and work through the scope in the order we wrote it down. Permits are pulled properly, materials are selected for San Antonio conditions, and the site is kept clean as we go rather than left as a wreck until the final day. If sub-trades are involved, we coordinate them so you’re not the general contractor on your own project.
- 5
Final walkthrough and written guarantee. When the work is done, we walk the job with you, address anything you see that isn’t right, and leave you with the written 365-Day Done Right Promise. If something fails in that year, we come back and make it right at no charge. That guarantee is the same one every Garrison brand carries, and it’s the reason we work as if the next job depends on this one, because it does.
How Much Does Construction Cost in San Antonio?
Construction pricing in San Antonio depends on scope, materials, and what the structure underneath is doing, but you should have real numbers to plan around. A small structural repair, like a rotted porch beam or a sagging joist, typically runs $800 to $2,500 depending on access and whether any finish work is needed. A bathroom remodel in a standard San Antonio home generally lands between $12,000 and $28,000, while a kitchen remodel runs $25,000 to $60,000 or more depending on cabinet grade, countertops, and how much plumbing and electrical moves. A room addition starts around $150 to $250 per square foot when tied into the existing slab and roofline, and it goes up from there if the foundation work is significant.
What affects the price most is what’s behind the walls: moving plumbing, upgrading an electrical panel, or repairing framing you didn’t know was damaged changes the number. That’s why we never quote a construction project over the phone without seeing it, and why we never let a number move at the door. Your free estimate from Garrison Partners includes the full written scope, so you can compare it against any other bid on the same footing. If you’re tired of estimates that come in low and invoices that come in high, we’re built to stop that exact pattern.

Frequently Asked Questions – Construction in San Antonio
Residential construction covers any structural, remodeling, or repair work done to a home, including additions, kitchens, baths, decks, siding, and structural repairs. In San Antonio, residential construction also means working with the city’s permitting requirements and building for local soil and weather conditions. At Garrison Partners, we define it by what we promise: written pricing, licensed and by-the-book work, and a one-year written guarantee on the finished job.
A small repair like a beam replacement or deck board repair typically takes one to three days once we’re on site. A full kitchen or bath remodel generally runs three to eight weeks depending on material lead times and what’s behind the walls, and an addition runs two to five months including permits, foundation work, framing, and finishes. We’ll give you a schedule in writing with your quote, and we keep you informed if anything changes rather than leaving you guessing.
The cost depends entirely on scope: small structural repairs often run $800 to $2,500, remodels run $12,000 to $60,000 or more by room, and additions run $150 to $250 per square foot. The single biggest factor is what’s behind the surfaces you can see, which is why we assess before quoting and put the price in writing before work starts. Call (409) 215-3468 for a free estimate with a fixed written scope.

You don’t need to prepare anything structurally; we’ll do the measuring, diagnosing, and scoping. The best preparation is writing down your questions so we can answer all of them during the walkthrough, before any work begins.
