If you have an exposed aggregate, stamped, or brushed concrete driveway, it needs to be cleaned & sealed every 2-3 years. The same goes for brick roadways & walkways – they should be cleaned, repaired (for any areas that have sunk), and then sealed. You can remove weeds, grass or ants from the cracks and joints to make it look like new.
When these paved surfaces are not maintained, the sun, chemicals, and general wear and tear can cut the surface life by up to 50%. Just as you paint your house and fix the sink, your paved surfaces need attention to extend their life and keep them functional.
