DPC Installation in North Shields

The streets that drop down the banks towards the Fish Quay are built into the hillside, and in some of those houses the back wall of the ground floor has earth or a raised yard against it for part of its height. A chemical damp course stops moisture rising, but it cannot stop water pushing through a wall that is partly underground. Those sections need tanking or a membrane, and the rest of the house can be injected as normal. We mark out on the survey which walls are which, so the quote covers each with the right method. In the Georgian townhouses near Northumberland Square, thick stone walls take the cream along the mortar joints at closer spacing, and the plaster afterwards has to be breathable. Hard modern plasters on those walls are often what made the damp worse in the first place.

In a Tyneside flat, the damp course work is nearly always in the lower flat, because that is where the walls meet the ground. The upper flat owner is usually unaffected, though the front elevation and the passage between the two front doors are shared ground. We can quote for the lower flat on its own, or for both owners together where the outside work affects both, which makes it simpler when two owners need to agree. Under-stair cupboards and the passage behind the front door in the lower flat are where damp often shows first, because they are cold, unheated and get little airflow. We read those areas along with the main rooms, since a patch in the cupboard can be the first sign of a wall that needs treating along its whole length.
