Have you noticed that the paint is peeling off the walls, or that a small damp patch has appeared under the window sill? I’m assuming that if this is the case you’ve attempted to just paint over it again and again? Does it work? Probably not.

It’s crucial to understand how to damp proof your home should the need ever arise. There are great damp proofing specialists based in Hampshire, Birmingham, London and everywhere else, but it’s very important to understand how to tackle the issue yourself first.  You should know exactly what to look for and what products you should use if you notice any damp. If you do not solve the problem immediately, damp will continue to grow.

Firstly you have to identify all of the damp areas and find out exactly what’s causing them. This can be a little tricky but you can eliminate some obvious damp proofing elements before you pay for a specialist to come out.

Is the damp at a high level or in an isolated area? You have to check outside for condensation overflow or pipes dripping from the brickwork. The constant source of water falling against the brickwork can be drawn into the internal finishes and manifest into damp patches and produce salt. If you can see this is happening you have to put an end to it immediately. By stopping the external source of damp you will completely rectify the problem, obviously.

Various structural defects will also cause excessive damp. Prior to purchasing a house you must have a thorough observation of the brickwork and structure, this will be done by a conveyancing company. If you’ve lived in your home for many years, routine checks are always in order to prevent any damp.

You have to have a damp proof course in your home, this is a physical barrier of slate that is situated above the internal floor levels and external ground level. This is an essential part of construction and will stop any rising damp manifesting. If this isn’t working properly you will need to re-install a cavity drain from the outside and solve the dampness internally.

There are few simple steps when tackling damp proofing. In order to complete this task you will need to purchase a DIY chemical injection kit, damp-proofing cream, a club hammer and a power drill.

Firstly you must remove the skirting board, or anything that could constrict your access to the damp. You must drill holes downwards above floor level or deep into the wall, it’s important to make sure these holes are evenly placed. Now you must insert the DPC fluid with an injection pump, the fluid will disperse and act as a water repellent.  Once the surface darkens and becomes wet you’ll be able to stop the injection pump.

You must leave the damp patch to dry for about a month before you fill the gap with a waterproofing agent. Only when this is complete can you go ahead and reinstall the skirting board.

I hope these tips help you and I wish you the best of luck resolving the problem!
