Check for leaks and blockages. Now is the perfect time when drains and gutters can get blocked by leaves and debris like twigs and bird nests.
If anything obstructs the easy flow of water away from a building, damp can occur. If you notice that water’s falling sharply from a certain point on a gutter, there’s probably a blockage there, so scoop it out with a trowel, taking full safety precautions if you’re using a ladder.
To stop gutters getting blocked, fit gutter guards, grates that block debris but still allow rainwater to get through.
