Pressure Washing Process.
Each job is unique, and we tailor our approach accordingly — however, these steps outline the typical process we follow for pressure washing.
Initial Inspection.
Not sure if your surface needs a light refresh or a more intensive deep clean? Whenever possible, Black Spot carries out an in-person inspection to assess the area accurately. We measure the space, evaluate the condition, and explain the cleaning process required — ensuring you're fully informed about the methods involved before any work begins.
Itemised Quote.
Following our initial inspection, we will provide a detailed quote for the job. All Black Spot quotes outline the individual steps required to complete the work to a professional standard. Each stage of the process is itemised, allowing you to see the steps involved along with the associated costs, ensuring complete transparency with no hidden charges at the end of the job.
Chemical Pre-Treatment.
Depending on the level of cleaning needed, some jobs could require a non-corrosive cleaning solution to be applied to target stains, moss, algae, and mildew. This fast-acting treatment breaks down contaminants, making them easier to remove and delivering instant results, while preparing the surface for a thorough clean.
Pressure Wash.
Once the pre-treatment has had time to work, we use high-powered pressure washing equipment to tackle dirt, grime, and any remaining debris. Our skilled technicians adjust the pressure levels according to the surface material, ensuring that delicate areas are not damaged — leaving your patio or driveway refreshed and rejuvenated.
Rinse and Detailing.
After the main pressure washing is complete, we perform a thorough rinse to ensure that all cleaning solutions, debris, and residue are fully removed. During this stage, we also pay attention to any tough spots that may require additional detail work. This ensures that the surface is completely clean and free from residue, providing a spotless finish.
Repointing & Sealing.
For added protection, Black Spot offers post-treatment repointing and sealant services. Repointing restores structural integrity, prevents water ingress, and improves the overall appearance and durability of your patio. The sealant creates a water-resistant barrier that guards against future stains and weathering, while also enhancing the surface’s appearance and helping to maintain a long-lasting clean.
Maintenance Plans.
Ensure your surfaces stay clean and well-maintained with our customised pressure washing maintenance plans. Regular visits help prevent the build-up of dirt, moss, and algae, saving you from costly repairs and keeping your patio or driveway looking its best throughout the year. A simple, cost-effective way to maintain the value and appearance of your property.
