Damp Prevention

Damp is usually caused by excess moisture getting into the property. This can be from rising damp (moisture coming up from the ground), penetrating damp (water coming through walls or roof), or condensation (caused by poor ventilation).

Signs include tide marks on walls, crumbling plaster near the skirting, peeling wallpaper, salt deposits, or a musty smell. Rising damp typically affects the lower parts of walls.

The cost depends on the type and severity of the damp. Simple condensation fixes may be inexpensive, while rising damp treatment or full damp-proofing can be a bigger investment. However, preventing damp early is cheaper than repairing long-term damage.

Yes. By tackling the source of moisture, treatments prevent the damp conditions that allow mould to grow. Additional ventilation may also be recommended to reduce condensation and stop mould from returning.

Small jobs like improving ventilation or applying surface treatments can take a day. More extensive damp-proofing or replastering can take several days to a week depending on property size and severity.

Often, yes. Even after damp-proofing, poor ventilation can still cause condensation. Installing vents, extractor fans, or air bricks helps keep moisture levels under control.

Yes. Damp and mould can trigger respiratory problems, allergies, asthma, and worsen existing health conditions. Tackling damp quickly helps protect your health.

With the right treatment—such as damp-proofing courses, tanking, or cavity drainage systems—damp can be permanently resolved. Ongoing maintenance (e.g., keeping gutters clear, ensuring good ventilation) also helps prevent recurrence.

In many cases, yes. Once damp-proofing is complete, affected plaster often needs removing and replacing to ensure salts and moisture don’t reappear.

Yes. RT Installation Systems provide guarantees, often ranging from 10 to 30 years depending on the method used. This gives peace of mind that the treatment is long-lasting.
