Natural stone is a statement of durability and elegance, but it isn’t immune to the elements. From the creeping spread of organic growth to the stubborn residue of a heavy construction project, your stone surfaces deserve more than just a high-pressure blast, they require a specialist’s touch.

Ace Power Washing restores the beauty of Ontario’s stone surfaces against our harsh seasonal weathering. We specialize in removing algae and lichens, alongside expert post-construction cleanup of cement and mortar smears. From stubborn rust and efflorescence to engine oil and limescale, we provide targeted solutions for every stain. Our team also offers professional stone repairs and mechanical cleaning to preserve your masonry. We invite you to explore our website to see the results.

How Do You Know Your Stone Needs Attention?

Sometimes it’s obvious, and sometimes it creeps up on you. Here are the most common signs we see when we visit properties for the first time:

  • Visible green or black algae, moss, or mildew
  • Efflorescence – deposits are white soft, powdery
  • Limescale, mineral deposits are hard, dense, and crusty
  • Staining from oil, rust, leaves, or general outdoor grime that regular hosing won’t shift
  • Slippery surfaces, especially dangerous on steps or walkways where algae has built up
Worth knowing: Algae and moss aren’t just cosmetic problems. Left untreated, they hold moisture against the stone surface, which accelerates cracking and deterioration,especially through freeze-thaw cycles here in Ontario. Catching it early saves you money in the long run.

Our Stone Restoration Process

We don’t just point a pressure washer at a surface and call it done. Every stone restoration job gets assessed first, and we tailor our approach to the material and what it needs. Here’s how a typical job goes:

  1. On-Site Assessment

    We walk the property with you, identify the surfaces that need work, and note any areas requiring extra care (loose stones, damaged mortar, deep staining, etc.).

  2. Site & Property Protection

    Before any water or chemicals are introduced to the site, a rigorous protection protocol must be executed to safeguard the property’s value and the surrounding environment (this includes: Organic saturation, surface masking & shielding, environmental runoff management)

  3. Controlled and Temperature Pressure Washing

    We adjust pressure levels based on the stone type. Softer materials like flagstone and natural limestone need a gentler touch than concrete pavers,and we know the difference.

  4. Deep Treatment

    Joints, edges, and hard-to-reach spots get individual attention to ensure the whole surface looks consistent when we’re done.

  5. Finishing & Optional Sealing

    We can discuss sealing options with you post-clean, which helps protect the surface and keep it looking better for longer.
