Rising Dampness
True 'rising' dampness will cause
damp to be evident in the walls but this dampness will not normally rise higher
than 1 metre. Most building products are porous and therefore able to draw
moisture from the ground. This moisture is then drawn up into the property and
drawn out of the walls to evaporate into the air. A DPC is installed to provide
a barrier to stop this moisture travelling into the property. |

Failed Damp Course
All new
construction will incorporate a DPC, usually 150mm above ground level. However,
in older properties which either didn't have a damp course installed or where
the original damp course has broken down, a new damp course is required. This
would normally be a "chemical DPC". |

Blocked Cavities
If cavities become blocked, the damp
course will be 'bridged' and water will penetrate the property. If dampness is
evident, a first step would be to arrange for
us to clear any debris from
the cavities. |

Bridged Damp Course
Dampness can occur within a property
when the damp course and/or the air bricks are "bridged". This often
happens when a patio is added or a new driveway is laid; both of these result in
the ground level being raised.
The usual minimum depth from damp proof course to ground level is 150mm. To
avoid dampness, ensure that any alteration to the ground bounding the property
does not encroach on the damp course or the air bricks. |

Condensation
Condensation tends to cause a black
mould growth on walls, particularly in corners or in areas where the air is
unable to circulate. Ensure that the property is adequately ventilated and has
air bricks fitted and extractor fans where water vapour is produced. A common
cause of 'dampness' is condensation caused by inadequate ventilation and
insufficient background heating; an imbalance between heat and ventilation. |

Blocked Air Vents
Air bricks can become obstructed
internally or externally. Ensure that air vents are free from obstruction to
maintain air flow. |

Penetrating
Dampness Through Walls
Dampness can penetrate a property
through the walls in the following circumstances:-
-
If debris within the cavity are
stilling on the cavity wall ties. Cavities will need to be checked and
cleared if necessary.
-
If the mortar between the
bricks has started to breakdown and is coming loose. If this is the case,
the brickwork will need re-pointing. This involves raking the mortar from
the joints and repointing with new mortar.
-
If bricks have become porous.
If this is the case, the damaged bricks will need to be replaced. In some
cases, it is possible to apply a water seal to the brickwork externally.

Leaking Gutters and
Downpipes
If guttering and downpipes are in a bad
state of repair, water will not discharge away from the property correctly and
can run down the walls. Over time, this can cause damage to the brickwork and
can result in the water penetrating the property. |

Defects in Roof Coverings,
Abutments and Valleys. Defective Chimney Flashings
Dampness within the roof space or
affecting the ceilings and walls of the rooms on the first floor can be caused
by defects in the roof covering. The roof can become defective following high
winds and rain or over a period of time through wear and tear. Regular checks
should be carried out to ensure that the roof is water tight. The easiest way to
check the roof is to go into the loft and check for any areas where daylight
is
coming through. However, this won't show up problems with the flashings or
blocked or slipped valleys or back trays. It is often a
good idea to have the roof checked, by an established roofing company, after any high winds or before the onset of winter. |
