Homes and yards across Weslaco
Weslaco is a short drive east of us in McAllen, between Donna and Mercedes, and the calls we get here are the ones we get all over the Valley. It's brick homes with mortar going sandy, block privacy walls along the back of the lot, and walks or patios that have dropped at one corner.
Most of what goes wrong here starts with water. The lots are flat, and after a hard rain water tends to stand in the yard and along the house instead of running off, so footings stay wet, walks settle and the bottom rows of brick take a beating. That's why I look at where your water goes before I talk about brick or block, and why we put as much care into the base nobody sees as into the wall everybody does.
Our services in Weslaco, TX
Brick low on Weslaco walls takes the most abuse because water sits there after rain. We cut out cracked or loose brick and set a close match, so the repair blends in.
Mortar on older Weslaco houses goes soft and sandy long before the brick wears out, letting water into the wall. We rake out the bad joints to an even depth and repack them with matched mortar.
Slow-draining soil is hard on any wall that starts below grade. Our foundation block wall installation starts with a level, well-drained footing, then block laid true with grouted, reinforced cores where the plan calls for them.
Many Weslaco yards have block privacy walls, and trouble usually starts at a footing or a cracked cap. We fix leaning or cracked runs and build new walls on footings built for ground that stays wet.
On flat Weslaco lots a driveway needs a slight pitch, or water pools at the garage. We pack a gravel base and set pavers to that slope, and a cracked paver can be swapped out alone.
A sunken or tipped Weslaco walk usually sat on soil that stayed wet. We dig out the soft ground, pack a solid base and slope the walk away from your house so water runs off.

How it works when you call us in Weslaco
Call or send a request
Call (956) 331-0202 or send the form, and we set up a time for me to come out to your Weslaco house. It helps if you can be there, because I'll have questions only you can answer.
I come out and look
I look at the wall, the joints or the ground with you and tell you plainly what I see, including when good brick should just be left alone. You get a free estimate, so you know where you stand before anything starts.
We handle any permits
If the job needs a permit, we take care of the paperwork with the city and set up the inspections. Once that's settled, we put your job on the calendar.
We build, clean up, walk it
My crew and I do the work ourselves and clean up the site when we're done. Then I walk the finished job with you so you can look it over and ask anything before we leave.
Weslaco masonry questions answered
How much does masonry work cost in Weslaco, TX?
The price comes down to the size of the job, the material and how much old work has to come out first, so the honest number is the one I give you after seeing it. Matching old brick and mortar, digging out wet soil for a new base and reaching a wall tucked behind landscaping all add time, while a straight new run of block on open ground goes faster. The schedule mostly turns on the size of the job and whether a permit is involved. Call (956) 331-0202 and I'll come out and give you a free estimate.
What causes standing water and flooding around Weslaco homes?
A regional drainage study blames drainage systems that can't keep up, soils that let water through slowly and land too flat for water to run off. That study is an older draft and looks at the Lower Rio Grande Valley as a whole, not single yards, but it matches what we see on jobs in Weslaco. So when a wall or a walk has moved, I look for where the water's going before I price the repair.
How do I find out if my Weslaco house is in a high-risk flood zone?
Look up your address on FEMA's flood maps, because that's the official answer for a single property. FEMA counts any place with at least a 1% chance of flooding each year as high risk, which works out to at least a one-in-four chance of a flood over a 30-year mortgage. If your lot is in one, it's worth knowing before you build a wall, a patio or anything low against the house.
Which energy code applies to a single-family home in Weslaco?
Texas sets a statewide minimum energy code, and for single-family homes it's the energy chapter of the International Residential Code. Other homes and commercial buildings fall under the International Energy Conservation Code, and the local jurisdiction is the one that enforces it. It matters for new walls around living space, like an addition, more than for a garden wall or a walk, and I'll talk it through with you when I come out.
What is the best way to keep a block wall from settling in Weslaco?
Start with a footing that's wide, level and sitting on firm, packed ground, then keep water from pooling along the base. Most leaning walls we see in the Valley were set on loose fill or a footing too shallow for ground that stays wet. A gravel strip along the base and a little slope away from the wall can keep water moving instead of soaking in.
Can you match old brick and mortar on a Weslaco house?
Usually, yes, and it's the work we're best known for, a repair where you can't tell where the old brick ends and ours begins. I match the mortar's color and hardness as well as the brick, because mortar harder than the old brick can crack the brick around it over time. And if your brick is sound and only the joints are tired, I'll tell you to leave the brick alone.
