Avoid calling out the professionals just yet as the following list of DIY tips might just be what you need to stop penetrating damp. Here are some common symptoms and remedies of a penetrating damp problem.
The wall tie between the cavity and the inner wall could be acting as a bridge for the penetrating water. Remove any mortar on the cavity wall ties to stop the water reaching the inner walls.
Damp patches around the chimney breast usually indicate a cracked or dislodged flashing seal (the joint between the roof and the chimney stack). You can try refitting the loose flashing, however, you may find it has been damaged in which case it will need replaced.
An isolated damp patch on your inner walls can be a sign of damaged pointing or cracked bricks. Replace all damaged bricks and fill any gaps in the mortar.
If you notice damp patches around the floor of an exterior door then try fitting a weatherboard which will help prevent water flowing under your door. You might want to check for any wet rot within timbers aswell.
Check downpipes regularly to ensure they are not blocked. Try using a flexible drain cleaning rod to unblock the downpipe. To prevent blocked downpipes try using a wire mesh or a plastic cap which will act as a filter at the top of the pipe allowing water through whilst catching any leaves or dirt.
Blocked or broken gutters normally lead to damp patches and black mould forming high up on walls. Clean away any rubbish blocking the gutters and replace any damaged ones. A Wise tip would be to clean your gutters out in late autumn after the leaves have fallen from the trees.
The inner side of an external wall may show signs of damp if the bricks have suffered from wear and tear which they can do over time. The bricks may need replacing or re-pointed. The affected area should also be treated with exterior silicone water-repellent fluid.
Check your household appliances regularly, especially the dishwasher, for any water leaking. Four common areas to check for a leaky dishwasher are the rubber gaskets, hoses, water inlet valve and the water level.
Any cracks within the rendering should be address immediately as it can allow water to enter your property. Try treating damaged rendering with acrylic sealants.
Do you notice damp patches on your ceiling after a heavy down pour of rain? It sounds though you may have a damaged or missing roof slate that is allowing rainwater to enter the property. These slates will need replacing.
Patches of damp around your windows usually indicates a gap between the wall and your window frame. Seal any gaps using a frame sealant. Also, check to see your exterior windows have an unobstructed drip groove which purpose is to prevent water flowing under the window and through the wall.
