Power washing

Surface cleaning for brick and stone.

Power washing removes dirt, soot and staining from the face of the masonry.

Grime and staining hide the condition of brick and stone. A clean face shows the joints, the cracks and the earlier repairs, so the masonry can be judged as it is.

NOVA Renovation offers masonry cleaning on its own, or as part of a restoration.

What cleaning is for

General guidance on why dirt and staining matter to masonry.

  1. Moisture

    Stains that point to water

    Dark streaks often mark where water runs off a sill or a ledge. Cleaning shows whether they come back.

  2. Repairs

    A face to match to

    New mortar and brick are easier to match to a clean face. New work then does not stand out.

  3. Inspection

    Seeing the wall

    Dirt, soot and staining hide cracks, open joints and failed repairs. A clean face can be judged as it is.

  4. Character

    The color of the masonry

    Brick and stone that have darkened over the years can look like a different material until they are clean.

What builds up on a face

What you might notice on brick, stone or a fireplace.

  • Dark streaks down the wall

    Staining that runs down from sills, copings or a chimney crown.

  • Dull, patchy color

    A face that has darkened unevenly, or looks dirty after rain.

  • Soot and smoke staining

    Blackened brick or stone around a firebox or a flue.

  • Rust stains

    Orange streaks running down from steel above a window or a door. Worth a look before any cleaning.

A guide, not a diagnosis.
