What causes rising damp?

Rising damp is caused by moisture travelling upwards through masonry from the ground when a damp proof course is damaged, bridged or missing.

What causes penetrating damp?

Penetrating damp is usually caused by water entering through external defects such as damaged brickwork, leaking roofs, faulty guttering or cracks in walls.

Can damp damage my property?

Yes. If left untreated, both rising damp and penetrating damp can damage plaster, timber, flooring and decorative finishes while contributing to mould growth and structural deterioration.

How do you treat rising and penetrating damp?

Treatment depends on the cause of the problem. Solutions may include installing a chemical damp proof course, repairing external defects, removing damaged materials and carrying out specialist remedial works.

Is rising damp more common than penetrating damp?

Penetrating damp and condensation are generally more common than rising damp, but all damp problems require accurate diagnosis to ensure the correct treatment is carried out.

Do you provide damp treatment throughout Yorkshire?

Yes. CS Damp Proofing Ltd provides professional rising damp and penetrating damp treatment for homeowners, landlords and commercial clients across Yorkshire, Teesside and the North East.

Stop damp before it spreads

Ground moisture and external water ingress require specialist attention, starting with finding out exactly how moisture is getting into your property. We inspect the affected areas carefully, check the condition of any existing damp proof course, and look for the real cause before recommending any work. Rising damp can leave tide marks, damaged plaster, peeling wallpaper and rotting skirting boards, especially in older homes across Yorkshire.

Penetrating moisture can creep through cracked walls, faulty guttering or roof defects, then show up as staining, mould and cold patches indoors. CS Damp Proofing Ltd carries out detailed damp surveys in Ripon and across the wider area to help you avoid bigger repair bills later. When the source is clear, we can put the right timber preservation work in place instead of patching over the symptoms.

A treatment plan that matches the cause

Ground moisture behaves very differently from rainwater ingress, so we treat each problem according to how it's affecting the building. Our survey looks at internal surfaces and external defects together, because a stained wall might point to failed plaster in one property and damaged brickwork in another.

Where needed, we install a new chemical damp proof course and remove contaminated materials that would otherwise keep drawing moisture back in. We can address defects linked to rainwater entry, such as cracked masonry or failed rainwater goods, before they cause more decay. You get honest advice shaped by 30 years of practical experience rather than unnecessary work.
