Following on from last week's blog, another thing that we are often called in to rectify is damp caused by the use of incorrect building techniques as well as the use of incorrect materials. Many old properties don’t have a damp course so water will penetrate through the brickwork and render, if the property can’t breathe. In addition, slabs had been laid uptight to the property. This caused bridging damp, where water penetrates through the external wall. This can then damage internal timbers and wall surfaces.
The basement was damp due to lack of ventilation and use of the wrong materials. We re-did this using thermalime plaster and also rebuilt the stairs.
We installed a French drain to stop any more rising damp and to allow the property to breathe again. You can read more about French drains on our previous blog.
