Why Proper Render Maintenance Matters

Eradicates Unsightly Staining:
Red, green, and black algae thrive on porous render, making your home look damp and neglected. We kill these organic infections at the root to restore the original color.
Prevents Long-Term Damage:
Algae and lichen hold moisture against your walls. During winter, this moisture freezes and expands, which can cause your expensive render to crack or blow off the brickwork.
A Fraction of the Cost of Painting:
Many homeowners think they need to repaint their stained render. A professional soft-wash restores the surface to a like-new condition for a fraction of the price.

Why We NEVER use high Pressure on Render:

High-pressure jets will instantly score, scar, and blow chunks out of modern render systems. Instead, we use a specialized "soft-wash" method. By applying professional PureSeal biocides at low pressure, we safely melt away organic staining without ever putting your walls at risk.

Our Cleaning Process

We survey your property to identify the specific type of render and assess the severity of the organic staining. This allows us to select the correct PureSeal chemical mix and provide a clear, accurate quote.

Frequently asked questions

Will pressure washing damage my render?

Yes, using high-pressure jets on render is highly destructive and can blast the face right off the masonry, leading to cracking and water ingress. That is exactly why we do not pressure wash render. Instead, we use a specialized "soft-wash" method that relies on chemical treatments rather than aggressive force to clean the surface safely.

What is soft-washing and how does it work?

Soft-washing involves applying professional, COSHH-compliant biocide treatments to your walls at very low pressure—similar to the pressure of a garden hose. These treatments get deep into the pores of the render to kill the root cause of the stains, breaking down the dirt without any risk of structural damage.

Can you remove those red, green, and black stains from my walls?

Absolutely. Those colored streaks are actually living organic matter—typically green algae, red algae, or black spot mold. Because our biocide treatments are designed to kill organic growth at the root, they completely eradicate these stains and keep them from growing back quickly.

How long does the soft-wash treatment take to work?

You will notice a dramatic improvement on the very same day. However, because our biocide treatments continue working and actively cleaning the surface over time, your render will often look even brighter and cleaner in the weeks following the treatment as the remaining dead organic matter is naturally washed away by the rain.
