Top 5 Signs Your London Stone Patio Needs Professional Cleaning | Expert Guide

By James Wilson, Head of Stone Restoration 8/11/2025

Is your stone patio showing signs of wear and tear? From stubborn algae growth to fading surfaces, discover the five critical indicators that your London stone patio needs professional attention. Our expert guide helps you identify common problems and understand when to call in the professionals. Learn how timely intervention can protect your investment and maintain your patio's beauty for years to come.

Is your stone patio losing its natural charm? As London's leading stone restoration experts, we've helped countless homeowners across Knightsbridge, Mayfair, and beyond restore their outdoor spaces to their former glory. Here are the telltale signs that indicate it's time for professional stone patio cleaning.

1. Stubborn Green and Black Staining

London's damp climate creates perfect conditions for algae and moss growth. If you notice persistent green or black patches that won't budge with regular cleaning, it's time for professional intervention. These organic growths can penetrate deep into the stone, causing long-term damage if left untreated. Our stone polishing service can eliminate these stubborn stains while preserving your stone's integrity.

2. Visible Efflorescence

White, chalky deposits on your stone patio are signs of efflorescence – a mineral buildup caused by water evaporation. While common in South Bank properties and other riverside locations, this issue requires professional attention to prevent permanent staining.

3. Fading and Discoloration

Has your once-vibrant stone lost its lustre? UV exposure and London's weather can cause natural stone to fade and discolor over time. Our limestone restoration techniques can rejuvenate your patio's original color and protect it against future weathering.

4. Uneven Surface Texture

If your patio feels rough or uneven underfoot, it could indicate surface erosion. This is particularly common in Fitzrovia properties exposed to heavy foot traffic. Professional cleaning and sealing can help restore smooth texture and prevent further deterioration.

5. Water Absorption Issues

Does water no longer bead on your stone surface? This suggests your sealant has worn off, leaving your patio vulnerable to damage. Learn more about protection in our guide to professional stone sealing.
