Penetrating Damp describes any circumstance whereby unwanted water enters the home from the outside. This can include leaks from broken plumbing or ineffective roofs, but also can describe ingress through rising damp, defective windows, poor pointing, spalled brickwork or down the chimney.
Problems related to Penetrating Damp
- Damage and staining to masonry, plaster and paint work.
- Moisture in timbers – this can lead to decay by wood rot or insect infestation.
- Further moisture related problems (i.e. cold, wet surfaces on which condensation can occur).
How to fix Penetrating Damp
There are as many ways to fix penetrating damp as there are ways for water to enter your home. It may be as simple as fixing a pipe or plugging a leak. The best advice is to identify the access point and try to stop the water there.
However there is a whole industry of tradespeople who are devoted to supporting your home’s fight against the weather – indicating that not all problems are easy to fix.
Water has an incredible ability to permeate solid building materials such as bricks, mortar, plaster and timber. Stopping this natural process can be extremely difficult. Professional damp-proofers have a number of techniques to repair such issues.
Complications arising from Penetrating Damp
As mentioned before, damp timbers and plaster can become a breeding ground for fungus, mould, rot and wood-boring insects. Removal of the water source will serve to restrict the damage caused by these problems. Unfortunately, once they are in your home, rot, fungal spores and woodworm are not easy to get rid of completely.
Rotting or infested timbers often require replacement and/or fumigation. This can be expensive depending on the areas affected.
