All you need to know about cleaning and sealing a driveway including materials, labour and time frames.
Sealing a block paved patio or driveway has many benefits, over and above looking elegant and stylish! A quality sealer will also protect and secure your paving from the elements and help to reduce usage wear and tear. Block paving is expensive, so sealing it is a sensible thing to do to protect your investment. Block paving can protect your paving from stains such as oil leaks from cars, helps to prevent algae and weeds from growing, lengthens the lifespan of the driveway by binding the jointing sand used and reduces the level of fading and wear, preserving the colour of your paving.
Cleaning and sealing a driveway will involve using a pressure washer to remove all traces of weeds, algae and any old stains. Then once the driveway is completely dry and clean, joints are refilled with kiln dried sand if required and all excess sand is removed from the surface. Finally, the sealer is applied using a brush, roller or a squeegee, as per manufacturer’s instructions.
You may want to consider cleaning and updating other areas of your home at the same time. The companies which offer driveway cleaning and sealing services will often also offer other brick & masonry cleaning services, which will be ideal for any walls which border the driveway to finish the job nicely - a sparkling clean drive bordered by grubby walls will not look great!
Driveway cleaning, sanding and sealing will typically cost between £8.50 and £12.50 per square metre. but the prices quoted will vary with location, the type of sealant and the size of the drive. The type of sealant used makes a big difference to the price, the most expensive of the sealants on offer is "Resiblock", but this product comes highly recommended.
Don’t bother paying to get your driveway sealed during the winter, there is simply too much moisture at ground level during the winter and the block paving won’t have the chance to fully dry out. Applying expensive sealant products like Resiblock is a complete waste of money when the blocks are damp as the seal will not last, in damp condition’s even if the surface appears dry it will still be holding moisture deep inside the material. So rather than sealing the paving against moisture, you will actually be sealing the moisture inside. Beware of any companies using pressure tactics to convince you to carry out this work at a reduced price during the winter months!
