Estimates are calculated from this rate. Final pricing can vary with property condition, staining, surface type, and access.
Limestone is everywhere in Austin, on home exteriors, retaining walls, entry columns, and patios. It is also one of the easiest surfaces to ruin with the wrong cleaning. Hi-Tech Power Wash specializes in limestone restoration, using stone-safe solutions and low pressure to lift stains, algae, and organic growth without etching or damaging the stone.
Limestone is soft and reactive, treat it that way
The wrong chemicals and too much pressure both damage limestone, etching the surface and leaving it worse than before. We test a small area first, then use stone-safe solutions and gentle technique to lift acorn and leaf tannin stains, mold, and the gray organic film that dulls Austin limestone. The stone comes back bright and intact.

Frequently asked questions
Can you clean limestone without damaging it?
Yes. We use stone-safe methods and solutions selected to protect natural limestone, work at low pressure, and test a small area first. Improper chemicals or excessive pressure are what etch limestone, which is why the stone needs a specialist rather than a general pressure washer.
Will I always get an instant limestone estimate?
In most cases, yes, at $0.40 per square foot. Heavy organic growth, rust or mineral staining, restoration work, difficult access, or specialty stain removal are different enough job to job that they get an on-site evaluation instead, so the number you get is accurate.
Can you remove acorn and leaf stains from limestone?
These tannin stains are common on Austin limestone and we remove them regularly. Severe, long-set stains may lighten rather than vanish entirely, and we will set honest expectations before starting.
How much does limestone cleaning cost in Austin?
Limestone cleaning is $0.40 per square foot, with a $250 minimum service charge per visit. Heavy organic growth, rust or mineral staining, restoration work, difficult access, or specialty stain removal can affect that number, so those situations get an on-site evaluation and a final quote before we start.
Will the limestone stay clean afterward?
Soft washing removes the organic growth at the root, so results last. In shaded or damp areas, an annual touch-up keeps the stone bright.
