Masonry contractor in Sinton, TX - repairs that hold up on clay ground
H&K Corpus Christi Concrete & Masonry repairs brick, mortar, chimneys and foundations on Sinton, TX homes, and builds the walls, walkways and outdoor kitchens people here keep putting off.

Our masonry work in Sinton, TX
We're based in Corpus Christi, and Sinton is one of the cities we work in, along with Portland and Robstown. The streets around downtown, near Sinton Street and the old county courthouse, hold a lot of older brick houses. Farther out it's mostly newer homes on slabs, bigger lots and open farm ground. Most of our calls here are about worn mortar joints, a chimney that's started to flake, or a yard project that's been waiting a few years.
The ground shapes most jobs here. The clay soil around Sinton swells when it's wet and shrinks in a dry summer, so a crack in a brick wall usually starts below it, and we look at the footing and the slab before we touch the mortar.
What we do for homes in Sinton
Foundation repair
When the clay under a Sinton slab dries out and shifts, cracks show up in the brick first, and we fix the cause before patching what you see.
Chimney repair
Older chimneys near downtown take years of Gulf wind and rain, so we check the crown, the concrete cap on top, and any loose brick first.
Tuckpointing
Mortar on Sinton's older brick homes wears out long before the brick does. We grind out the soft joints and pack in fresh mortar that matches.
Brick repair
A spalled brick, one whose face has popped off, lets water into the wall behind it, so we cut it out and set one that matches your house.
Driveway pavers
Pavers suit the long driveways on Sinton's bigger lots because a sunken spot can be lifted and reset, and the base underneath decides how long they stay flat.
Retaining wall construction
Around flat Sinton lots, our retaining walls usually hold a raised bed or a small grade change, with drainage behind to keep wet clay from pushing them out.
Masonry restoration
Some of the brick houses close to downtown deserve to be brought back, not covered up, so we clean, repoint and repair them with matching materials.
Fireplace installation
Sinton gets a few cold nights, so a new fireplace is often about the room, and we still size the flue, the smoke passage, so it draws right.
Stone veneer installation
Stone veneer, a thin face of real or cast stone, gets a drainage layer behind it, because Sinton's damp air will find any spot that can't dry.
Concrete block walls
Block walls make good property lines and privacy walls on the bigger lots around Sinton, and we fill and reinforce the cores to stand up to Gulf wind.
Foundation block wall installation
For an addition, a pier-and-beam home or a raised floor out on farm ground, we lay block foundation walls on a footing sized for the clay underneath.
Outdoor kitchen masonry
Long, warm evenings make an outdoor kitchen worth building here. We build the base in block, face it in brick or stone, and fit it to your grill.
Walkway construction
Where a front walk has heaved or sunk on Sinton clay, we dig out, pack a proper base and lay brick, stone or pavers to keep it even.
Brick wall installation
A brick garden or screen wall suits the older brick houses near downtown, and we set it on a real footing because clay moves a short wall too.
Stone masonry
Stone handles long Sinton summers well, so we use it for columns, mailbox posts, entries and planters, laid by hand with mortar mixed to suit the stone.
Brick pointing
If only a few joints have cracked or washed out, pointing fills just those, which is often all a Sinton brick home needs between bigger mortar jobs.
What should Sinton homeowners watch for in their brick?
Between storms off the Gulf and long, humid summers, Sinton brick takes a beating from above as well as below, so small signs are worth a look.
- Stair-step cracks in brick walls
- Mortar that crumbles when scratched
- Doors or windows that start sticking
- Loose or flaking chimney brick
- White powder streaks on brick
- Walkway or pavers heaving or sinking
If you spot one of these, call or send the form and tell me what you're seeing. I'll come out and give you a straight answer, even if it's nothing.
Repair the brick or rebuild the wall?
In Sinton the answer usually turns on what's under the masonry. If the footing and the ground have stopped moving, a repair usually holds, and if they haven't, patching just buys time.
When a repair is enough
The cracks are old and haven't grown, the brick is sound, and it's mostly the mortar that's worn. We repoint the joints, swap out the damaged brick and match the color, so the wall keeps its original look.
When rebuilding makes sense
A wall that leans, bulges or keeps cracking after repairs, or a chimney with brick loose from the top down, needs taking apart. We rebuild it on a sound base, and I'll tell you plainly when that's where we are.
What Sinton's ground and weather ask of masonry
I come out to look at every job myself, and I'm on site with our crew while the work gets done, so the person who quoted it is there when it's built.
Licensed and fully insured
Every Sinton job, from a few joints to a whole wall, is done by a licensed and fully insured crew.
Permits handled with the city
Sinton wants a building permit before structural work like foundation repairs, and when yours needs one, we apply and keep you posted.
Mortar matched to old brick
On older Sinton brick we mix a softer mortar to suit it, because mortar harder than the brick cracks the brick instead.
Your estimate in writing
I put what moves the price and schedule in writing: how much masonry, matching old brick, access, and any permit review.
