Damp proofing specialists you can trust
Damp Proofing Specialists with over 25 years’ experience in the building and construction industry.
Guardian Damp Proofing covers the North Wales area, specialising in Property Care and Preservation including damp proofing, timber treatments, condensation control and water proofing.
Every property is different. We assess the cause before recommending a solution, so the work we carry out addresses the source of the problem rather than the symptoms.
Diagnosing the problem
Damp can be caused by a number of various issues
The most common form of damp is caused by condensation, rain penetration or rising damp. Identifying which one you have is the first step to solving it.
Rain penetration
Driving rain finds its way in through defective masonry, pointing, roofs or failed rainwater goods.
Rising damp
Where a damp proofing course is missing, bridged or faulty, moisture rises from the ground into the walls.

Outstanding, professional company.
Excellent company, very professional, honest appraisal of what work needing doing and a very reasonable price! All great guys, hardworking, tidy, very friendly, we highly recommend them!
Excellent company
These guys were brilliant! A prompt reply to my initial enquiry, Dan explained everything that needed doing in detail, 100% honest, did the job at a very fair price and actually did more than we expected. We have already asked them to do another job for us!
Excellent from start
Excellent service from the start. Communication all along. Kept to agreed dates and times. Tidy and courteous workers. Took all the rubbish away and left the room very tidy. Excellent standard of finish. Would recommend.
So pleased with the entire experience
I cannot recommend this company more highly. Their work is just top notch and they are so thorough when it comes to the treatment process. Meticulously clean, and the crew are a joy to work with. Dan is brilliant at communicating and honest as the day is long.
Reliable company with good standard of work
Dan and his team did a good job of tanking my garage. I was kept well informed of progress and Dan answered any questions promptly, including making an extra visit to check the first layer of tanking. I would use Guardian again and recommend them to others.

Write a reviewThe technical bit
Damp proof course(DPC)
If your property does not have a damp proofing course (DPC) or the damp proofing cause is bridged or faulty, dampness will be able to rise through the ground into your walls.
Bridging can be as simple as raised external ground levels or a render that crosses the course. A survey identifies exactly where the protection has failed — and what it takes to restore it.
