💧 Penetrating Damp – It’s Often Not the Wall That’s to Blame! 🏡
One of the most common causes of penetrating damp we find isn’t a failed damp-proof course at all—it’s defective rainwater goods and bridging caused by external render or high ground levels.
When gutters become blocked, cracked, or start overflowing, large volumes of rainwater continually soak the external masonry. Over time, this moisture penetrates through the wall, leading to damp patches, damaged plaster, peeling paint, mould growth, and even timber decay if left untreated.
Another issue we regularly encounter is bridging. This happens when external render, paths, patios, or raised ground levels are too high against the property, allowing moisture to bypass the original damp-proof course and enter the wall.
At The Property & Damp Company, we don’t believe in simply treating the symptoms. Every survey is carried out to identify the true source of the moisture ingress before recommending the correct remedial solution.
Typical remedial works may include:
✔️ Repairing or replacing defective gutters and downpipes.
✔️ Reducing external ground levels where they are bridging the damp-proof course.
✔️ Removing external bridging render and reinstating it to the correct height.
✔️ Repointing defective brickwork and repairing damaged masonry.
✔️ Applying breathable waterproofing systems where appropriate.
✔️ Replastering internally using specialist damp-resistant systems once the source has been eliminated.
The key to successful damp remediation is accurate diagnosis, not guesswork.
If you’re noticing damp patches, peeling plaster, mould growth, or signs of water ingress, arrange a professional survey before spending money on unnecessary treatments.
