Damp Proofing Quotes in Portstewart Northern Ireland

If you're suffering with rising damp in a property constructed after this date it might be that your DPM has been damaged somehow.

Rising Damp Portstewart Northern Ireland

Solving rising damp issues can be as simple as checking your home's external walls and seeing if you can spot a damp proof course. It ought to be 150 millimetres (around 6 inches) above the level of the ground for adequate protection. Where you find this space does not exist, you can dig the earth away to increase it, or if this process isn't feasible, a higher DPM will have to be installed.

If this isn't the root cause of the problem and your DPM is correct, there could be more problematic issues to resolve caused by the dampness coming up from the ground, through your floor, and into the walls of your property.

Portstewart damp proofing experts will quickly be able to determine the cause of your rising damp, and using a number of procedures will soon take care of the problem. A damp proofing cream (such as Dryzone) can be carefully injected into your wall if you have an older house with no damp proof course, or one that's damaged over a significant area. Holes are drilled at intervals along the brickwork, and a special nozzle is used to inject the cream, which then diffuses before curing to form an effective waterproof barrier.

If the damp proof cream isn't suitable, or the damage to your membrane is too extensive, a brand new damp proof course might have to be installed. Though this is obviously a pretty extreme course of action, it may be the only method to remedy your damp issues effectively.
