A proper patio clean starts with checking the surface, not just turning up and blasting it with pressure. This first step helps decide the safest pressure, treatment and cleaning approach for sandstone, porcelain, concrete and natural stone patios.
We check the patio material, staining, joints, drainage and risk areas before choosing the safest cleaning method. This page explains what this stage does, why it matters, and how it supports a better patio cleaning result.
Why Surface Assessment Matters
Different patios react differently to pressure. Indian sandstone can be softer and more open textured, porcelain is usually denser but can hold marks in textured surfaces, and older concrete slabs can have weak edges or tired joints. A surface assessment reduces the risk of damage and improves the final result.
What this step includes
- Identify the patio material and condition
- Check for black spot, algae, moss, lichen and ingrained dirt
- Look at joints, pointing, drainage and nearby delicate areas
- Choose the safest pressure and treatment approach
- Spot areas that may need extra care or repeat treatment
Common Problems This Step Helps Avoid
Mistakes with poor patio cleaning
- Using the same pressure on every surface
- Cleaning loose pointing too aggressively
- Missing blocked drainage points before starting
- Not checking for delicate edges, old slabs or weak joints
