Retaining Wall Cleaning

Remove stains, algae and buildup to refresh and protect retaining walls.

Retaining Wall Cleaning for Charlotte-area homes

Retaining walls hold water and shade, so they collect algae, stains and buildup faster than flat surfaces. We clean the face and the caps so the wall matches the restored hardscape around it.

Signs it is time

Green or black streaks run down the wall face
The caps are stained or discolored
The wall looks darker than the patio or walkway next to it
White mineral deposits show on the block or stone
Moss or algae grows in shaded sections

Questions about retaining wall cleaning

Why do retaining walls stain faster than patios?

Walls stay damp longer, often sit in shade and catch runoff from the soil behind them. That suits algae and mineral deposits.

Can you clean the wall and the patio at the same time?

Yes. Cleaning both together gives a consistent finish across the whole hardscape.

What are the white deposits on my wall?

White deposits are usually efflorescence: salts carried to the surface as water moves through the block or stone. Cleaning removes them, and keeping water moving away from the wall helps stop them coming back.
