Flooring in West Lake Hills, and What Sits Under It

Directly on the fault

West Lake Hills sits on the Balcones fault zone itself, and that is the least predictable ground in our entire service area.

Everywhere else in this corridor we can tell you which side of the escarpment you are on and reason from there — stable limestone to the west, moving clay to the east. Here the boundary runs through the neighbourhood. Faulted blocks put limestone and clay-rich material against each other at short distances, and it is genuinely possible for the conditions under one end of a house to differ from the other.

That is not a reason to worry. It is a reason not to accept a generic answer about your slab, and a reason we survey rather than assume. Two houses facing each other across a street here can behave differently, and the one next door tells you less than it would in Cedar Park.

Mid-century custom, which complicates everything

The housing here is predominantly 1960s to 1980s and heavily custom, sitting on steep, wooded, rocky lots.

That produces three recurring complications.

Stepped and multi-level slabs. Houses were built into the slope rather than on a pad, so a single property may have three or four floor levels. Every step is a transition to detail, and every one is a place where a floating floor needs an expansion break. A flatness reading in one room predicts nothing about the next.

Layers of previous work. Sixty years of renovation means what is under a floor is genuinely unknown until it comes up. Sheet vinyl over adhesive, later tile over that, plywood underlayment sandwiched between. Pre-1985 sheet vinyl with a felt backing is a testing question rather than a demolition one, and it gets settled before anything is disturbed.

Real hardwood worth saving. Unlike the tract stock further north, houses of this era and this quality frequently have genuine solid hardwood under later carpet. Restoring it is usually both cheaper and better than replacing it, and it is worth lifting a corner before deciding.

Refinishing, and how many sandings are left

Where solid hardwood is present in a house that has changed hands several times since 1970, the question is not whether it can be sanded but how many sandings it has left.

A solid board tolerates roughly six to ten across its life, and previous owners’ sandings count against that budget. We check the thickness at a floor vent or a door threshold before agreeing a floor can be sanded at all. If this is the last sand the floor will take, you should know that before you spend the money, because it changes what you do next time.

Access and logistics

Steep, narrow, wooded lots with tight driveways are the norm. It affects material delivery and it occasionally affects which grinding equipment can reach a house.

It is not an obstacle, but it is a reason an estimate here is written after a visit rather than over the phone, and a reason a quote that arrives without anyone having seen the driveway should be treated carefully.

Tile on faulted ground

Because the substrate here is genuinely variable rather than uniformly stable, we are more conservative about rigid tile than we would be in Bee Cave four miles west.

Where a survey shows anything suggesting movement — an existing crack pattern, doors that have changed behaviour, an older tile field that has failed along a line — a crack-isolation membrane goes into the specification rather than being offered as an upgrade. It appears as its own line so you can see the cost and the reasoning together.
