Power Washing 101: When and Why You Should Clean Your Stonework
Your stonework is built to last, but like anything exposed to the elements, it needs proper care to keep looking its best. Over time, dirt, moss, stains, and grime can build up on patios, walkways, driveways, retaining walls, and other stone features — dulling their appearance and even affecting their longevity.
That’s where professional power washing comes in. At Kings Stoneworks, we don’t just install stone — we help maintain it. In this post, we’ll break down everything you need to know about power washing: what it is, why it matters, and when to schedule a clean.
What is Power Washing?
Power washing (also called pressure washing) is the process of cleaning surfaces using high-pressure water. For stone surfaces, this helps remove:
Dirt and dust buildup
Moss, algae, and mildew
Oil, tire, and rust stains
Salt and other winter residues
Organic debris from trees or nearby landscaping
When done correctly, power washing restores the look of your stonework without damaging the material. It’s a fast, effective way to bring back the natural color and texture of your outdoor surfaces.
Why Clean Your Stonework?
1. Preserve Appearance
One of the main reasons homeowners power wash their stonework is simple — it just looks better. Over time, your once-vibrant patio or driveway can start to look tired and discolored. Power washing revives that original clean, sharp look and boosts your property’s curb appeal.
2. Prevent Long-Term Damage
Moss, algae, and other organic buildup can trap moisture, which leads to deterioration — especially during Toronto’s freeze-thaw cycles. Power washing removes this growth before it can cause cracks, shifting, or staining that might require costly repairs down the line.
3. Improve Safety
Slippery buildup like moss or mildew isn’t just unattractive — it’s a slip hazard, especially on walkways and stairs. Power washing keeps your surfaces clean and safe for everyday use, especially in damp or shaded areas.
4. Prep for Sealing or Repairs
If you’re planning to reseal or repair your stonework, power washing is an essential first step. It ensures the surface is clean and clear, so sealants or jointing materials adhere properly and last longer.
When Should You Power Wash?
Knowing when to schedule a power wash can help you keep your stonework in peak condition. Here are a few helpful guidelines:
▸ Spring Cleaning (After Winter Wear)
Winter can be tough on stonework — snow, ice, salt, and sand all leave behind grime and residue. Spring is the ideal time to refresh your surfaces and assess any damage caused by freeze-thaw cycles.
▸ Before and After Special Events
Hosting a backyard gathering, open house, or family event? A quick power wash will make your patio, porch, or entryway look freshly installed. After a heavy-use season, it’s also great for restoring cleanliness.
▸ Once a Year for Maintenance
As a general rule, we recommend homeowners power wash once a year to prevent buildup and maintain your stone’s natural beauty. However, heavily shaded areas or high-traffic surfaces might need more frequent care.
▸ Before Resealing or Repairs
As mentioned earlier, power washing before applying new joint sand, sealants, or making repairs ensures a better bond and longer-lasting results.
