Regularly pressure washing your driveway and treating it with a biocide or sodium hypochlorite is essential for maintaining both its appearance and structural integrity. Driveways are constantly exposed to traffic, weather, and organic growth such as algae, moss, and mildew, which can make surfaces slippery and accelerate wear. Professional pressure washing removes embedded dirt and contaminants, while biocide or sodium hypochlorite treatments kill organic growth at the root and help prevent rapid regrowth. For block paved driveways, the cleaning process can remove degraded jointing sand, making re-sanding necessary to stabilize the blocks, prevent movement, and stop weed growth. Applying a sealant afterward helps lock the sand in place, enhances color, reduces staining, and provides long-term protection against moisture and organic buildup—ultimately extending the life of the driveway and preserving its curb appeal.

Pressure washing your decking is essential for maintaining its appearance, safety, and longevity, as dirt, algae, mold, and mildew can quickly build up and create slippery, hazardous conditions. Treating the deck with a professional biocide after cleaning is equally important, as it kills organic growth at the root and helps prevent rapid regrowth, keeping the surface cleaner for longer. However, it is critical that decking is not pressure washed at too high a pressure, as excessive force can damage the wood or composite surface by splintering fibers, causing etching, or lifting boards and fixings. Using the correct pressure, techniques, and treatments ensures the deck is thoroughly cleaned without compromising its structure, preserving its finish and extending its lifespan.

Pressure washing your patio is an important part of maintaining a clean, safe, and long-lasting outdoor space. Over time, patios accumulate dirt, algae, moss, and mildew, which can cause staining and create slippery, unsafe surfaces. Professional pressure washing effectively removes these contaminants, while treatments such as biocide or sodium hypochlorite kill organic growth at its root and help prevent it from returning too quickly. During the cleaning process, worn or loose jointing material between the slabs may be removed, making re-sanding or re-pointing necessary to maintain stability and prevent weed growth or water penetration. Applying a sealant afterward helps protect the surface and joints, enhances the natural appearance of the patio, reduces staining, and provides long-term resistance against moisture and organic buildup, ensuring your patio remains attractive and durable for years to come.
