Detecting a blockage early can prevent water from seeping into your home's foundation. Look for these warning signs:

Moreover, the sludge that accumulates in a blocked pipe is a rich nutrient broth. It supports the germination of seeds dropped by birds or wind. It is not uncommon to find grass, weeds, and even small trees sprouting from the top of a blocked downpipe. These root systems are biological jackhammers; as they grow, they exert immense pressure on the joints and seams of the guttering, exacerbating leaks and ensuring the blockage becomes permanent. blocked downpipe guttering
