What we build

Stonework thatstays put.

Pick one piece or the whole project. We do the boring parts — base prep, drainage, edge restraint — right, so the surface on top is still tight a decade later.

Paver Patios

Concrete paver and natural-stone patios set on compacted base — the foundation work that keeps the surface flat ten years later.

from $4,800 · project-based

Flagstone Walkways

Texas Oklahoma flagstone, set on a stable base with hand-cut joints — the kind of path that gets compliments from the curb.

from $2,400 · project-based

Retaining Walls

Engineered block, segmental, or full mortared stone walls — with the drainage and geo-grid behind them most crews skip.

from $3,600 · project-based

Paver Driveways

Driveway-grade pavers on a thicker base — load-rated for daily vehicle traffic, not just foot traffic.

from $9,500 · project-based

Brickwork & Stonework

Veneer, columns, mailbox piers, garden walls — masonry done with mortar joints that line up and stay tight.

from $1,800 · project-based

Pergolas & Outdoor Rooms

Cedar pergolas anchored into stone columns or footings — built to handle a Round Rock summer wind, not just a Pinterest photo.

from $6,800 · project-based

Drainage Solutions

French drains, channel drains, and re-grading — because no patio survives a yard that pools water against the slab.

from $1,400 · project-based

Fire Pits & Outdoor Kitchens

Stone fire pits and built-in outdoor kitchens — with the gas runs and ventilation specs the city actually requires.

from $2,200 · project-based

How a project goes

Four steps from grass to finished patio.

Most of the work the visitor never sees is in steps one and three. That’s why the patio is still tight a decade later.

01

Plan

Walk the property, read the slope and the drainage, sketch the layout. Measure, cost, contract — no surprise change-orders mid-build.

02

Lay

Excavate to depth, compact a four-to-six inch crushed-base substrate, geotextile underlay, screed level. The stone won’t move because the base won’t move.

03

Set

Pavers or stones placed by hand, every cut made on-site so the joints are tight. Edge restraint pinned along the perimeter. Joints filled with polymeric sand.

04

Seal

Activate the polymeric sand, sweep the surface clean, walk you through the finish. Optional sealant for color depth and easier cleaning.

From the project book

A few we’ve put down recently.

Each one was a different yard, a different stone, and a different drainage problem. We took notes on every job — these are pulled straight out of the book.

Wood Glen — Round Rock

Material
Holland pavers + limestone seat wall
Size
420 sq ft
Time
9 working days

Drainage cut into the back curve so the slope sheds toward the yard, not the slab. Seat wall doubles as planter on the inside face.

Forest Creek — Round Rock

Material
Texas Oklahoma flagstone, dry-laid
Size
38 linear ft
Time
4 working days

Every slab cut on-site for a tight gait. Decomposed-granite base, polymeric joint sand, hand-tapped level.

Cat Hollow — Hutto

Material
Mortared limestone, two-tier
Size
Lower 32 ft, upper 26 ft
Time
12 working days

Geo-grid every 18 inches, perforated drain wrapped in fabric, daylit at the south corner. Permitted — passed inspection first try.

Mayfield — Pflugerville

Material
Large-format pavers + cedar pergola
Size
560 sq ft + 12x14 pergola
Time
14 working days

Pergola posts coordinated with the paver layout so every base lands on a full stone — no awkward cuts at the columns.

We don’t lay stone on top of a problem. The base, the drainage, the cuts — that’s where the work lives.

In their words

What homeowners say

Some of the homeowners we built patios, walls, and walkways for over the last two years.

Nathan walked the property with us before the bid, pointed out a drainage issue two other crews missed, and built the patio around it. Six months and one Round Rock thunderstorm later — bone dry and the joints are still tight.

Caroline H.

via Direct

Hired Mastermind for a flagstone path and a small retaining wall. They cut every stone to fit on-site instead of forcing the layout — you can tell from the joints. Fair price, no surprises, no leftover gravel piled on the lawn when they left.

David M.

via Direct

Wanted a paver patio with a built-in fire pit and a small pergola. Nathan coordinated all three so the post locations land on full pavers — most crews would have just cut around it. The seams line up and the pergola is rock-solid.

Good to know

Frequently asked

  • Twenty-five to forty years if the base is built right. The pavers themselves outlast the homeowner — the failure point is almost always the substrate. We over-build the base on every patio so settling and edge-spread never become your problem.
