Rising damp is the action of water moving vertically through porous building material, which is in contact with the ground. This is brought about by the drying action of air on the upper surfaces which causes the wall to act like a wick, drawing water upwards from the ground by capillary action, which then evaporates from the surface into the atmosphere. The moisture will continue to rise until it reaches a height where, unless evaporation is possible, gravity pulls it down again.
Rising damp occurs because the building’s damp proof course (DPC) has broken down or is being bridged by high ground. A DPC installed during construction will be a physical layer of impermeable material. This can consist of slate, bitumen impregnated felt or plastic, for example. Many older properties do not have a DPC.
Where appropriate, PTL will install a chemical DPC system to control the problem. The chemical DPC is injected into the walls at regular intervals. There will often be a small level of moisture held in the substrate due to salt contamination even when rising damp is controlled. Re-plastering will replace the salt contaminated plaster and protect the decorated surface from any residual moisture held in the wall.
Our CSRT trained Surveyors (Certified Surveyor in Remedial Treatments) will assist in assessing your damp problem and providing the best possible solution.
We believe our depth and range of knowledge coupled with our dedication to providing high levels of customer service are the cornerstones of our continued success. As a result of this dedication many of our earliest clients continue to consult us.

Testimonials
Vince, Matt and Tony – were the best workmen we have ever used – and we’ve used many in several old houses over the past half century; amazingly careful, tidy, efficient and we were never made to feel that our home was “the site”.
“Thank you for your report – it was very comprehensive and highly professional. Many thanks again for your excellent service.”
“I have been pleased with the three who were responsible for the work so please pass this on to David Morton. They were very professional in their approach, pleasant individuals, careful inside the house and have left the property tidy.”
“Ivan has just left, having done a wonderful job in tanking out our vault. It looks beautiful. He was very careful and tidy and considerate in his work, and also extremely pleasant and patient with my questions!”
Just a quick note to thank Alan and David for all their help. I asked a lot of questions and they were very patient explaining.
I would like to pass on my many thanks to your team who have been very professional through the process. In particular, Paul the surveyor was top class. He turned up on time, was very polite & charismatic, and very clearly examined and explained the situation to me for which I was most grateful.
“Richard was the point of contact I spoke to, he was courteous, informative and outlined the plan of action at the start of each day. They cleaned up very well, I couldn’t fault it.
“Your Operative did an excellent job, undertook the work in a clean and tidy manner, and was polite and courteous; he is a great ambassador for all those professional standards PTL aspire to!”
‘Huge thanks to you all for a brilliant service from start to finish. The wall looks better than it has for the last year, even without the re-decorating, yet!’
“Both operatives were very personable and professional – and did a fantastic job! I’m thrilled with the result. Thank you.”
