The Best Ways to Clean and Reseal Block Paving Effectively

Block paving is one of the most attractive and durable choices for driveways, patios, and pathways. However, like any surface exposed to the elements, it requires regular care to keep it looking its best. Over time, dirt, weeds, algae, and general wear can affect its appearance and longevity. Cleaning and resealing block paving not only enhances its visual appeal but also protects it from long-term damage. At Haddenham Driveways, we understand the importance of maintaining your investment properly, so here’s how to clean and reseal your block paving the right way.

Why Cleaning and Resealing Block Paving Matters

Without maintenance, block paving can quickly lose its charm. The gaps between the blocks can collect dirt and debris, encouraging weed growth and allowing moisture to seep through. Regular cleaning removes surface contaminants, while resealing adds a protective layer that:

  • Prevents staining from oil or dirt
  • Reduces weed and moss growth
  • Enhances colour vibrancy
  • Protects against water penetration and frost damage
  • Extends the overall lifespan of your paving

A well-maintained block paved surface not only looks impressive but also remains structurally sound for many years.

Step 1: Prepare the Area Properly

Before you begin cleaning, clear the area of vehicles, garden furniture, and any other obstructions. Remove loose debris such as leaves, soil, and small stones using a broom or leaf blower. This step ensures you don’t grind dirt deeper into the surface during cleaning.

Inspect for Damage

Check for any sunken areas, loose blocks, or damaged sections. If you spot any problems, it’s best to have these repaired by professionals at Haddenham Driveways before cleaning and sealing — this prevents further deterioration and ensures an even finish.

Step 2: Clean Thoroughly and Carefully

High-pressure washing is one of the most effective ways to clean block paving, but it must be done with care. Excessive pressure can dislodge the jointing sand or damage the blocks’ surface.

Best Practices for Pressure Washing

  • Use a moderate pressure setting and a wide spray nozzle.
  • Work in even, sweeping motions rather than focusing on one spot.
  • Start from the highest point and work downwards to prevent dirty water from running over cleaned sections.

Once the area has been cleaned, allow it to dry thoroughly before proceeding to the next step.

Step 3: Refill the Joints

After cleaning, you may notice that some of the jointing sand between the blocks has been washed away. It’s essential to replace it to maintain stability and prevent weed growth.

How to Refill the Joints

  • Use kiln-dried sand and spread it evenly over the surface.
  • Brush it into the joints using a soft broom until all gaps are filled.
  • Lightly compact the surface to ensure the sand settles properly.

This stage ensures the blocks stay firmly locked in place, preventing movement and uneven surfaces.

Step 4: Apply the Sealant

Sealing your block paving protects it from staining, fading, and moisture damage. A high-quality sealant acts as a weatherproof barrier and enhances the natural colours of the blocks.

Tips for Effective Sealing

  • Only apply the sealant once the paving is completely dry.
  • Use a roller or sprayer for an even coat.
  • Apply two thin coats rather than one thick layer for better absorption and durability.
  • Avoid walking or driving on the surface until the sealant has fully cured.

At Haddenham Driveways, we use premium-grade sealants suited to the local climate in Haddenham and Cambridgeshire, ensuring lasting results and a professional finish.

Step 5: Maintain Regularly

To keep your block paving looking great after cleaning and resealing, perform light maintenance throughout the year.

  • Sweep away debris regularly to prevent moss and dirt build-up.
  • Spot clean stains before they set in.
  • Reapply a sealant every few years, depending on usage and exposure.

Routine care keeps your surface in excellent condition and reduces the need for major cleaning or repair work later.
