Limestone Cleaning & Restoration in Austin, TX
Limestone cleaning from $299
Limestone is everywhere in Austin, from home exteriors to retaining walls, fireplaces, and entry columns. It is also one of the easiest surfaces to ruin with the wrong cleaning. Hi-Tech Power Wash specializes in limestone restoration, using pH-neutral 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
Acidic cleaners and high pressure both damage limestone, etching the surface and leaving it worse than before. We use pH-neutral, stone-safe solutions and gentle technique to remove 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 pH-neutral, stone-safe solutions and low pressure. Acidic cleaners and high pressure both etch limestone, which is why limestone needs a specialist rather than a general pressure washer.
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 typically runs $299 to $599 depending on the area and the level of staining. Get an instant ballpark with our estimate tool.
Can you clean limestone fireplaces and interior stone?
Yes. We clean interior and exterior limestone, including fireplaces, columns, and retaining walls, using stone-safe, low-odor solutions.
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.
