Top Tips for Cleaning Brick and Render Surfaces Without Damage
Top tips for cleaning brick and render surfaces without damage. Brick and render are both popular finishes for homes across Edinburgh, the Lothians, Fife, the Borders, and the surrounding areas — but like any external surface, they’re exposed to Scotland’s unpredictable weather. Over time, dirt, moss, algae, and pollution can build up and spoil your property’s appearance.
At Dunse Power Cleaning, we often get asked: “How do I clean my brick or render without causing damage?” The truth is, using the wrong cleaning method can actually make things worse — so here are our expert-approved tips to help you get it right.
Why Brick and Render Need Special Care
Brick and render are strong materials, but they’re not immune to damage. Harsh cleaning techniques — especially high-pressure washing — can:
🚫 Strip away protective surface layers
🚫 Expose the inner structure to moisture
🚫 Cause cracks or premature wear
This is why it’s essential to use the right approach for long-lasting results.
Top Tips for Cleaning Brick and Render Safely
🧼 1. Inspect the Surface First
Before any cleaning starts, inspect the area for:
- Cracks
- Loose mortar
- Flaking render or exposed brick faces
Cleaning over these problems can push water deeper into the structure, making it worse. Always repair first, clean second.
💧 2. Avoid High-Pressure Washing on Delicate Areas
While pressure washing is excellent for driveways and patios, brick and especially render can suffer under too much force. If pressure washing is used, the correct setting and nozzle type must be selected to avoid stripping away surface layers.
At Dunse Power Cleaning, we adjust our equipment to suit the material, ensuring an effective clean without any damage.
🌱 3. Use Soft Washing for Render
For most modern renders, soft washing is the safest and most effective cleaning method. It combines:
- Low-pressure water application
- Environmentally friendly cleaning solutions
- Gentle rinsing
This method removes dirt, algae, and moss without harming the surface or encouraging future growth.
🧪 4. Apply Suitable Cleaning Solutions
Using the right cleaning agents is key. We recommend using:
- Biocides to tackle moss and algae growth at the root
- pH-neutral detergents for general dirt and grime
- Avoiding strong acids or harsh chemicals, especially on painted surfaces, stone, or older brickwork
Professionals like us know which solution to apply for different surfaces, ensuring a deep clean without risk.
🧹 5. Don’t Forget Preventative Maintenance
Once cleaned, regular upkeep can stop dirt and algae from returning:
- Keep gutters clear to prevent water overflow onto brickwork or render
- Trim back plants and trees near walls to reduce moss and algae growth
- Arrange professional cleaning every 1-2 years, depending on your location and exposure
