Frequently Asked Questions

There are many factors that can influence the amount of regrowth, we recommend a deep clean of your driveways & patios every 2-3 years. 

However, the lifespan of your results depends on three main factors:

• Surface Material: Concrete and tarmac results usually last 12+ months. Block paving typically needs a refresh after 9 months, as the jointing sand can attract new weed seeds over time.
• Environment: If your property is in a shaded area or near the wooded parts of the Woodford Valley, moss and algae may return faster (within 6 months) due to moisture and lack of sunlight.
• Biocide Treatment: Unlike pressure washing which removes surface dirt, a Biocide treatment soaks into the surface and kills any organic spores like moss, algae, and lichen at the root. This creates a self-cleaning effect. The treatment stays active in the surface for 9-12 months, preventing green regrowth far longer than water alone.

Most residential jobs in Salisbury are completed within 2 to 5 hours, depending on the property size and services required.

• Driveway Pressure Washing: Typically takes 2–5 hours. This includes setup, deep cleaning, and rinsing down. If re-sanding is required, we usually return on a dry day for a final 1-2 Hour application.
• Gutter Cleaning: Gutter cleaning usually takes 1–2 hours. Using a high-reach gutter vacuum system allows us to clear debris quickly and safely from the ground.
• Combined Service: If you book both together, we can typically complete the entire job in a single morning or afternoon session.

In Salisbury and the surrounding Wiltshire area, professional driveway cleaning typically costs between £150 and £350, depending on the size and surface material. Most local homeowners can expect to pay around £4 to £6 per square metre for a professional pressure wash and treatment. 

• Surface Material: Block paving often costs more than tarmac or concrete because it requires re-sanding with kiln-dried sand, once the cleaning is complete to maintain structural integrity.
• Level of Soiling: Driveways with heavy black spot lichen, moss, or oil stains may require specialist chemical treatments called biocides. Which can add £80+ to the total as this is a specialist product.

, we use professional-grade, HSE-approved cleaning chemicals and sanitisers to ensure a deeper and longer-lasting clean than water alone can provide.

While we only use chemicals, when necessary, they are essential for professional results for the following reasons:

• Pressure washing alone: Pressure washing alone will not remove black spot lichen or mould. Our biocide treatments target the roots, to help reduce regrowth reappearing as quickly.
• Preventing Regrowth: High pressure water cleans the surface, but it doesn't kill organic spores. Our treatments act as a sanitiser to prevent the rapid return of weeds and moss. We recommend a 9 monthly biocide treatment to help with the ongoing maintenance to exterior surfaces.
• Surface Protection: Using the correct chemical technique called soft washing allows us to clean delicate surfaces without the risk of damage from excessive water pressure.
• Targeted Purpose: Every chemical we use in Salisbury is chosen for a specific purpose, whether it’s lifting oil or eliminating algae, ensuring the best possible finish for your property.

Our team is fully trained in the application of these treatments. We prioritise the safety of your home, using only HSE-approved products that are biodegradable and safe once dry.

• The Drying Phase: The treatment typically takes 1–3 hours to dry depending on the Salisbury weather. Once there is no visible moisture or pooling on the surface, it is perfectly safe for paws and little feet.
• No Harmful Residue: Unlike DIY products, our professional biocides break down naturally and do not leave behind corrosive salts or toxic fumes.
