We might have enjoyed a dry summer, but with autumn just around the corner, leaks and damp at home are something to watch out for.
There are different kinds of damp, and sometimes you need a surveyor to identify which is which, but here are some basic pointers.
Penetrating damp usually moves horizontally from the outside in but patches can also appear on ceilings and floors as well as walls.
Missing or loose flashing; missing, rusting or blocked guttering; defective pointing and bricks, and cracked or missing render typically cause penetrating damp.
If the damp is at the bottom of a wall, it’s usually rising damp, in which case the solution is a new damp proof course (DPC).
Sometimes, the DPC is just being prevented from doing its job. You should be able to see it (providing there is one) along your home’s exterior brickwork.
Perhaps you’ve noticed damp on a chimney breast, or where the chimney breast would have originally been?
This could be because the chimney stack needs to be repaired, the chimney pot isn’t capped, or the chimney breast isn’t ventilated properly indoors.
When a fireplace opening is sealed up, a vent should be fitted, but vents can get blocked with dust and debris. If there isn’t a vent, don’t delay in fitting one.
Other common causes of damp are problems with the roof. All roofs should be inspected regularly and maintained when necessary.
