DPC Installation in Durham

Durham's streets climb out of the river valley, and many terraces in Gilesgate and the villages around the city step down a slope. On those houses the original damp course steps too, and the ground floor inside may be higher or lower than the pavement outside. We set the injection line to the floor level inside, stepping it where the floor steps, so the barrier sits where it can protect the room. Back walls cut into the slope can have earth against them, and those need a different treatment from injection, which we tell you about if we find it. Front steps up to the door are another detail on hillside streets, as they are often built against the wall and can carry water into it, so we check those as part of the survey.

In a terrace the party wall is shared, and it is common for one owner to treat their side while next door does nothing. Injecting your side still stops moisture rising in your half of the wall, and we treat the party wall from your side only. For landlords, we put the work, the walls treated and the guarantee in writing, which is useful when a letting agent, a tenant or a future buyer asks what was done. We also plan around tenancies where we can, so a let room is stripped, injected and replastered in the gap between one tenant leaving and the next moving in, with time allowed for the plaster to dry before the room is redecorated. If the room has to be used sooner, we say so and leave it ready for a breathable paint.
