Our Process

The Softwash Solution

We treat the infection, not just the symptom.

1. Biocide Application

We apply a specialist biocide to the affected area. This is not just a cleaner; it's a treatment that penetrates the surface to kill the root system of moss, algae, and lichen.

Deep Penetration: Reaches the roots

Sterilisation: Kills invisible spores

2. Natural Cleansing

Once treated, the dead organic matter will weather away naturally over time with wind and rain. The surface actively resists new growth for months or even years.

Long-Term: Results improve over time

Maintenance: Fewer cleans needed

Black Spot

Removes stubborn lichen.

Red Algae

Treats unsightly wall stains.

Why Remove Moss & Algae?

The benefits of our professional biological treatments.

Prevents Damage

Moss holds water against surfaces, which can freeze and cause cracks in roof tiles, brickwork, and render.

Long Lasting Results

Our biocide treatments kill spores at the microscopic level, keeping surfaces cleaner for far longer than pressure washing alone.

Safe Soft Washing

We use low-pressure application methods that are safe for delicate surfaces like K-Rend, older roofs, and heritage stone.

Red Algae Removal

We effectively treat and remove the stubborn red streaks (Trentepohlia) often found on light-coloured walls.

Improves Safety

Algae on paths and decking is incredibly slippery. Our treatment removes this hazard, making your garden safe.

Stops Regrowth

The residual effect of our biocides continues to work after application, preventing new spores from germinating for months.

Price Promise

The price quoted includes all labour, equipment, and biocide solutions – no hidden extras. A home in Maghera gets the same fixed, upfront quote as anywhere else we cover.

Fully Insured

We carry full public liability insurance, giving you complete peace of mind while we work on your property.

Frequently Asked Questions

Common questions about our moss and algae treatments.

Why does moss come back after pressure washing?

Pressure washing only removes the visible growth. The spores and roots remain deep in the porous surface and quickly regrow. Our biocide treatment kills the root system, ensuring a much longer-lasting clean.

Is the treatment safe for my pets?

Yes, once the treated surface is dry, it is completely safe for pets and children. We take precautions during application to keep everyone safe.

How long does the treatment take to work?

You will see immediate results as we clean the surface, but the biocide continues to work for weeks, lightening the surface and preventing regrowth. The "self-cleaning" effect on roofs can continue for months.

Will it damage my roof tiles?

No. We use a "Soft Wash" method which relies on the cleaning product rather than high pressure. This is the recommended method for cleaning roofs as it avoids damaging the delicate surface of the tiles.

How often should I get this done?

Every surface is different and requires varying levels of maintenance with location, vegetation and climate all being a contributing factor to rate of regrowth. Ask our specially trained applicators for tailored advice relating to your specific needs.
