    Rising Damp 20 year Warranty

    Rising damp (or salt damp) is not the most common form of dampness encountered in buildings; this is left to condensation. However a high proportion of older buildings are affected by rising damp to some degree or another. In general, walls prior to the 1970s did not have damp courses or inferior ones, which allowed the damp to rise in capillary action. Rising damp can be more serious than just causing aesthetic damage, structural damage to the base of the wall can also occur.

    Condensation and Dampness

    Condensation is by far the most common cause of dampness in buildings, probably accounting for the majority of damp problems reported. It affects both old and new buildings, and can be a significant problem where the building has been modernised. Although it's the most common cause of damp it's not the only cause you may have rising damp. Condensation is directly associated with mould growth which is associated with many health problems.

    Sub-floor Ventilation

    The modern vents Anti-Damp uses for under floor ventilation provide 8 times more air flow than the old fashion terracotta type vents. They come in 4 different sizes and 4 different colours. Warm air can hold more water as vapour than cool air. One should also be aware that the problem can occur well away from the site of most water vapour production. E.g. water vapour produced in the kitchen may diffuse through the house into a cold bedroom where it will condense on cold walls.

Hi Barry

I would just like to thank you and Tony and for the great job done on sorting out our under floor ventilation.

Your advice made most sense (of all the companies I got quotes from) and the focus on quality and especially house aesthetics was very refreshing,

Tony, who did the installation of the actual ventilation bricks did a great job! The quality of his work was excellent, he asked the right questions, made some good suggestions and even cleaned up nicely at the end. 

I will wholeheartedly recommend anti-damp to anyone who has underfloor ventilation issues.

Kind regards Dimitri

Barry and the team were very helpful in giving specific advice for our situation. Not only did they do a fantastic job with the vents to keep the under house area dry but also recommended builders and spoke to them on our behalf to further solve our damp issues. Great service and they came and went and kept things neat and tidy. Highly recommend barry to give advice about damp issues you may have. 

The builders HBuild  Huw principal

Formed more than 25 years ago and even the newest employees have over 5 years experience in the industry.

We are one of the few companies who offer both physical and the chemical pressure injected damp proofing methods. We believe the chemical pressure injection method, which has been perfected over many years, is far superior to any other type of damp proofing solution. There are many advantages of this solution the most important one being no large-scale disturbance of the structural integrity of the building. The damp / water proofing fluid that we use is of the highest quality available, it is also odourless and safe to use.

Although we advise the use of chemical pressure injected damp proofing should the customer prefer information on or to use the more traditional physical damp course proofing, we can do that as well. Some companies still insist on using the physical damp course method which I believe is more often than not for profit reasons i.e. less materials and a higher cost per lineal metre means a higher profit for some. We prefer to give value.

Normally we do not offer any plastering or rendering repairs as part of the job, however as well as specialising in damp proofing I am also a licensed Plasterer and therefore qualified to give advice in this area. We are always happy to advise and make recommendation but as a minimum we advise the customer that a suitable salt retardant should be used in the plaster mix.

Another major trading area of Anti-Damp is under floor and wall ventilation systems. We believe that with proper ventilation many damp situations can be alleviated before they cause major problems. There are several methods of ventilating a building and we design the ventilation system to suit the building in question. In general however we find that the most efficient system is the wind powered turbo, this method is powered by wind as the name suggests. It is silent Running, trouble free, and will lasts for years. It forces the existing vents in the building to work harder and reduce musty smells in the under floor area. We have other systems as well which include brass wire ventilators and 12V fans.

As you can see we do a wide range of work which means that we are not restricted in our view of how to solve a problem. Our company motto is “don't fix something that isn't broken” and we believe we get more business this way and the customer is always happy.

Thank-you for visiting our web-site and I hope to hear from you so that we can be of further service.
