Rising Damp Treatment Services

Are you looking for damp proofing professionals for rising damp in your home?

Rising damp is one of the most serious yet misunderstood damp problems that affects properties across the UK.

Treating true cases of rising damp will often involve installing a remedial damp proof course, and the earlier this can be performed the more likely you are to avoid creating an unpleasant and damp environment in your home. Also, if left to accumulate, the excess moisture content in the wall can reach the timber resulting in wet or dry rot. 

How to identify Rising Damp

Understanding what rising damp looks like, and how it differs from a penetrating damp problem or dampness caused by condensation is not always easy if you are not trained in what to look for.

Our surveyors come not only with the high-class training but also the highest standard certification which helps in analysing and identifying rising damp in your home.

Penetrating Damp treatment in Portsmouth

Penetrating damp is the result of water infiltrating a building or property through the external wall, defective pointing, cracks in the roof or floors.

There are several signs that you may have a penetrating damp problem in your home:

  1. Water marks or stains on walls, ceilings, or floors
  2. Peeling or flaking paint or wallpaper
  3. Musty or mouldy odours
  4. Rotting or crumbling wood
  5. Damp or humid patches on walls or floors

If you notice any of these signs in your home, it is possible that you have a penetrating damp problem. It is important to address this issue as soon as possible, as penetrating damp can cause structural damage to your home and can also have negative health effects if left unchecked.

Make Your Property damp-free!

We visit your property first and perform a damp survey to determine the real and the subsidiary causes of the dampness. Our specialists check all potentials points of water ingress, such as the cracks on the walls, blocked gutters, and more. When these points of water infiltration are established our team will provide you with a cost-effective quote for the remedial work.

what does a damp survey include

“Highly professional damp treatment…”


“Advanced Damp were highly professional in the damp treatment service they provided us. We found Sam’s very clear explanation of the treatment, steps for follow-up, and advice on another possible area of damp in the house all very helpful. He was on time, and committed to tidying up as part of the service.

We really appreciated Sam’s immediate response to the request we placed on the website, and the fact that he could fit us in so quickly. We wouldn’t hesitate to recommend these services.”

~ Bruce

“Practical, helpful approach…”


“Super-prompt, efficient, courteous and tidy service from Gary and his son Ben. I had lots of concerns about getting the damp treatment to fit in with some improvement work we had planned and some unplanned insurance work, and their practical, helpful approach and detailed advice has taken a huge weight off my mind.

They really tailored what they did to what we needed, and will be doing some more work for us to fit in with the schedule we have to work to. I’d have no hesitation in recommending them.”

~ Jane

“Sorted quickly and efficiently…”


“My rising damp problem was sorted quickly and efficiently by Advanced Damp.

The boys were excellent at their job and explained to me what they were doing and why, every step of the way. I felt confident that they were experienced in the problem. I will definitely use them again.”

~ Christine
