The three simplest things you can do to keep your patio/paving looking as good as new are:

Use a yard brush to sweep off debris/leaves/dirt and don’t let it accumulate
Pressure washing the patio can remove stubborn dirt and stains, and restore the patio to its original colour. However, there are risks involved with this, and if you’re not comfortable handling it yourself, we are happy to provide you with both one-off and regular patio cleaning services.
With older patios and paths, a major problem tends to be weeds making their way through any gaps. Try to keep on top of these by removing them by hand, or using weed-killer products. Again, this is a service that we can provide.
