Why is this something to consider?
If it’s slippery, green or tired-looking, It’s not past saving.
Professional pressure washing and treatment can safely remove organic growth, restore appearance, and extend the life of your surfaces, often at a fraction of the cost of replacement.

Driveways are exposed to constant traffic, weather, and organic growth. Over time, this leads to algae, moss, and ingrained contamination that makes surfaces look tired and slippery — even when the structure underneath is still sound.
Our Cleaning Process
Every driveway is assessed before work begins. We identify the surface type and condition to ensure the safest and most effective cleaning method is used — avoiding unnecessary damage while delivering the best possible result.
Professional Cleaning & Treatments
Where suitable, we apply professional-grade treatments designed to break down organic growth at its source. This allows contamination to be safely removed during controlled pressure washing.
On more sensitive surfaces, alternative biocidal treatments are used to achieve effective results without compromising the material.
Re-Sanding & Finishing Touches
Following cleaning, jointing sand can be re-applied where required to restore stability, improve appearance, and help reduce weed regrowth. Optional sealing is also available for added protection and enhanced appearance.
Ongoing Care
We also offer after clean maintenance plans in form of a soft wash every 6 months to help keep driveways cleaner for longer.

How We Clean & Restore Your Patio
Every patio is different, so our process begins with a full assessment of the surface type, condition, and level of contamination.
Surface Assessment
We identify the material (concrete, natural stone, porcelain, etc.) and check jointing, drainage, and any existing damage to ensure the correct cleaning method is used.
Pre-Treatment (Where Appropriate)
For patios affected by algae and organic growth, we apply a professional-grade sodium hypochlorite solution at carefully controlled ratios. This breaks down organic contamination at a cellular level, allowing growth to be safely removed rather than simply blasted off the surface.
On more sensitive materials, alternative biocidal treatments are used to achieve effective results without risking surface damage or discolouration.
Controlled Pressure Washing
Once the treatment has had time to work, we use surface-appropriate pressure washing to thoroughly rinse and clean the patio. Pressure levels are adjusted to suit the material, ensuring an even clean without etching, pitting, or joint damage.
Joint Restoration
Where required, joints are cleaned out and re-sanded to restore stability, improve drainage, and enhance the finished appearance.
Optional Sealing
Sealing can be applied to help protect the patio from future staining, inhibit regrowth, and enhance colour depth, leaving a longer-lasting, easier-to-maintain finish.
Aftercare & Ongoing Maintenance
Following cleaning, we provide guidance on keeping your patio looking its best. Periodic re-treatment can help prevent regrowth and maintain a clean, safe surface year-round. Maintenance plans are available for customers who want long-term protection with minimal effort.

Timber decking is constantly exposed to moisture, UV light, and organic growth, which causes it to fade, discolour, and become slippery over time. Without the correct cleaning methods, decking can easily be damaged. Our decking cleaning and restoration service is designed to safely revive timber surfaces, restore natural appearance, and extend the lifespan of your deck.
How We Clean & Restore Your Decking
Timber requires a completely different approach to hard surfaces. Every deck is assessed before work begins to ensure the correct process is used.
Timber Assessment
We inspect the decking to identify timber type, condition, fixing method, and level of contamination. This allows us to choose the safest cleaning method and avoid issues such as raised grain, splintering, or surface damage.
Pre-Treatment (Where Appropriate)
Organic growth is treated using timber-safe biocidal solutions designed to break down algae and biological contamination without bleaching or harming the wood. Unlike harsh methods, this allows growth to be removed gently rather than forced out of the grain.
Controlled Low-Pressure Cleaning
We clean the decking using low-pressure techniques appropriate for timber. Pressure levels and nozzle selection are carefully controlled to remove contamination while preserving the integrity of the wood fibres.
This prevents common problems such as:
• Furring (raised grain)
• Striping or uneven cleaning
• Damage to fixings or joints
Rinse & Neutralisation
The deck is thoroughly rinsed to remove residues and ensure the surface is clean, stable, and ready for use or further treatment.
Preparation for Finishing
Following cleaning, we apply a timber-safe biocidal treatment to inhibit the regrowth of algae, moss, and organic contamination. This treatment works over time, continuing to protect the surface after cleaning and helping to keep your decking cleaner and safer for longer.
Biocidal treatments are particularly effective on shaded or damp decking areas where growth returns quickly.
Aftercare & Maintenance
Decking benefits from regular maintenance. We provide advice on aftercare and offer maintenance cleaning plans to help prevent regrowth, reduce weathering, and keep your deck looking its best year after year. This comes in the form of biocide treatments every 6 months.

All chemicals used in our pressure washing services are biodegradable. Proper PPE and processes will be strictly followed. Method statements & proof of insurance can be requested by the customer.
