Moisture problems? We can assist.

Damp is one of the most frequent problems encountered within the average home or business. Dealing with damp should be a top priority. To treat rising damp it is imperative to identify the source and apply the appropriate solution as soon as possible to prevent further damage.  This will save you time and money before the problem becomes insurmountable. We use top-of-the-range damp proofing products to address your damp problems. We offer a friendly professional service with guaranteed results and a complete and permanent solution.

At Thorn Damproofing Contractors we have been working with complexes since the 80’s, and each project comes complete with its own set of unique problems that require a specific solution. For that very reason we put together a detailed report in order for the client to best assess how they would like to solve the issues relating to damp.

Do not put your assets at risk due to poor advice or incorrect assessment of the damp issues – we have the experience and professional systems in place to ensure that your requirements are met in a professional manner. Please contact us to set up an appointment to discuss your solutions.
