Where We Install Floors, and What Is Under Them

Twenty communities, working outward from Leander across four counties. They are grouped by the ground they sit on rather than alphabetically, because the ground is the thing that changes our answer and the county line is not. The Balcones Escarpment runs north to south through the middle of this map and separates two different worlds: up on the plateau a slab sits on rock and stays where it was poured, and out on the Blackland a slab rises and falls with every wet and dry season. A floor specified for one of those and installed on the other is the single most common failure we get called out to.

Edwards Plateau

Up on top of the escarpment, where soil is measured in inches and the slab was poured on rock or on cut caliche. These floors barely move. When one of them is out of level it has been out of level since the pour, which changes the whole repair conversation: you are correcting a defect, not chasing a season.

• Liberty Hill, TX Williamson County · 78642 Liberty Hill is acreage and very new construction on the Edwards Plateau, where well water hardness and slabs that have not finished curing both come up.
• Bee Cave, TX Travis County · 78738 Bee Cave sits on stable Edwards Plateau limestone, which is why large-format tile and stone are viable here in a way they are not east of the escarpment.
• Dripping Springs, TX Hays County · 78620 Dripping Springs is fast master-planned growth on stable Edwards Plateau limestone, where many houses run on wells or collected rainwater rather than city supply.

Edwards limestone

The 183A growth corridor. Same hard limestone shelf, but under an enormous quantity of 2005-and-later tract housing — which means builder-grade carpet reaching the end of its life all at once, and slabs that were poured fast on ground that gave the crew no margin for error.

• Cedar Park, TX Williamson County · 78613 · 78630 Cedar Park sits on the Edwards limestone shelf with karst voids underneath it, so slabs here are stable but rarely flat, and grinding does more than pouring.
• Georgetown, TX Williamson County · 78626 · 78628 · 78633 Georgetown pairs one of the largest active-adult communities in Texas with a Victorian courthouse square, so slip resistance and 1890s pine both come up here.
• Lakeway, TX Travis County · 78734 · 78738 Lakeway has been building continuously since the 1970s on stable Edwards limestone, so the era of the house decides the job far more than the ground does.
• Brushy Creek, TX Williamson County · 78681 Brushy Creek is late-1980s and 1990s housing on Edwards limestone, old enough that most floors here are already on their second or third replacement.

Marble Falls limestone

The Lake Travis shoreline communities. Older limestone above the flood pool, steep lots, and a housing mix that runs from 1970s weekend cabins to current custom builds on the same street.

• Lago Vista, TX Travis County · 78645 Lago Vista is Lake Travis shoreline living, where houses sit unconditioned between visits and a floor has to survive swings a lived-in house never sees.
• Jonestown, TX Travis County · 78645 Jonestown mixes 1960s and 70s lakeside cabins with recent construction, so what is underneath an old floor here is genuinely unknown until it comes up.

Llano granite

Out past the Colorado into the Llano Uplift, where the bedrock changes from sedimentary limestone to granite and gneiss and the soils turn coarse and sandy. Different ground from anywhere else on this list, and it drains accordingly.

• Marble Falls, TX Burnet County · 78654 Marble Falls sits on the Llano Uplift where the bedrock turns from limestone to granite, giving it coarse sandy soils found nowhere else in our service area.

Balcones boundary

Directly on the fault zone itself. This is the least predictable ground in the service area — limestone and clay can change inside a single lot line, and two houses facing each other across a street genuinely behave differently.

• Austin, TX Travis County · 78704 · 78751 · 78756 · 78759 Austin straddles the Balcones fault, so a pier-and-beam bungalow in Hyde Park and a slab in the east of the city need genuinely opposite advice.
• West Lake Hills, TX Travis County · 78746 West Lake Hills sits directly on the Balcones fault zone, where limestone and clay can change inside a single lot and mid-century custom homes complicate every survey.

Austin Chalk

A hard, chalky limestone under the eastern Williamson County suburbs. It sits between the plateau and the black clay in every sense: firmer than Taylor Marl, more mobile than the Edwards.

• Round Rock, TX Williamson County · 78664 · 78665 · 78681 Round Rock sits on Austin Chalk, between the stable limestone west of it and the moving Blackland clay east — which is why the city has both kinds of floor problem.

Colorado terrace

River-terrace gravels and sands along the Colorado arm. Well drained, mixed lot by lot, and the reason two neighbouring properties can need different substrate work.

• Volente, TX Travis County · 78641 Volente sits on Colorado River terrace deposits above Lake Travis, where drainage varies lot by lot and no two slabs on a street behave identically.
• Spicewood, TX Travis County · 78669 Spicewood is acreage on Colorado River terrace ground west of the lake, where properties run on wells and substrate conditions change lot to lot.

Taylor Marl clay

Off the escarpment and onto the Blackland. Highly plastic clay with severe seasonal shrink and swell — this is where a slab genuinely moves through the year, where rigid tile telegraphs it, and where an uncoupling membrane stops being an upgrade and becomes the specification.

• Pflugerville, TX Travis County · 78660 · 78691 Pflugerville sits on Taylor Marl clay that swells and shrinks every year, which is why floating floors and crack isolation are specifications here, not upgrades.
• Hutto, TX Williamson County · 78634 Hutto pairs the most active clay in the corridor with some of its newest slabs, so both seasonal movement and incomplete slab cure are live issues here.
• Jarrell, TX Williamson County · 76537 Jarrell is among the newest housing in the corridor, sitting on Taylor Marl clay where slab cure and seasonal movement both bear on a first floor replacement.

Blackland Prairie

The deep black clay east of the corridor. The most mobile ground we work on and the oldest housing stock, so pier-and-beam and slab problems turn up in the same neighbourhood.

• Taylor, TX Williamson County · 76574 Taylor has real early-twentieth-century housing on the deepest black clay in our service area, alongside a new-build fringe growing around the semiconductor investment.
• Manor, TX Travis County · 78653 Manor is rapid new construction on deep Blackland clay east of Austin, where slab moisture and seasonal movement both bear on every flooring decision.

Not on the list? Ask. The limit is not really mileage, it is the return trip: a sand and finish means being on site on consecutive days including the coating days, and past a certain drive that stops being schedulable honestly. If you are past it we will say so and give you a name closer to home, rather than book you and let the dates drift.
