We will get back to you to talk the job through.

There is nobody better in San Antonio. We do it once, we do it right, or we don't do it. We value honesty and integrity in all aspects of our business, and we offer a range of services customised to each individual project. We pride ourselves on the quality of our work and on our commitment to outstanding results. We look forward to building lasting relationships with our clients, and we guarantee your satisfaction.
We focus on installation services only, and are not currently providing repair services. New patios, walls, borders and walkways are what we do, and we would rather tell you that up front than take a call we cannot help with.
Phil and the crew are the ones on site. One customer describes two projects in 2025 — a paver walkway, then a paver patio in the back yard — and another has had them back three times.
The thing customers write about is the stone itself. One wrote that Phil “is rough and rugged and knows how to work with stone” but is “also an artist and can see what we cannot regarding stone”, and that they had used him for three projects. That is the whole pitch: somebody who looks at a pallet of irregular flagstone and sees where each piece goes.
The work runs from a mailbox column to a full flagstone patio, an outdoor kitchen or a limestone retaining wall with steps built into it.

"Before and after picture below :) Phil is a fantastic individual, and while he is rough and rugged and knows how to work with stone, he is also an artist and can see what we cannot regarding stone. We've had him for 3 projects now. This is our back patio. Thanks Phil and team!"
Worked with us? We'd love to hear how we did.
