Moisture ingress and drainage

Make sure you’ve got sufficient drainage to an appropriate outfall.


Don’t let the damp drain your resources. When it comes to moisture and damp, it’s often what you don’t see that can be the culprit. Making sure the water has a place to go, and that it can’t linger underneath is an essential part of keeping your property dry.

In a nutshell

Let the rain drain away!

The drainage system must include gutters, downpipes and drains for the removal of water from the roof.

What lies beneath?

The subfloor. That’s the bit under the house if there is space above the ground. If your rental has one of these and it is enclosed then a ground moisture barrier must be installed if it is reasonably practicable to do so.

Deny the damp

A ground moisture barrier sounds more technical than it is. Basically, it’s just there to block the moisture in the ground from rising into the property. It also helps to prevent moisture damage to the underfloor insulation

Check the pipes

Check the pipes are in good nick and have somewhere appropriate to drain to.
