What is penetrating damp?

Penetrating damp, another name is lateral damp, is the result of water penetrating from the outside of a building and into your property causing problems to exterior and internal walls if not recognised and dealt with at an early stage. Unlike rising damp, penetrating damp can happen at any level within the property including roofs, ceilings and walls, it is most commonly caused from leaky pipes, broken gutters, poorly maintained brickwork, deterioration of mortar joints showing cracks which over time can become damaged or need re-pointing, crack stitching may be needed in some cases, water management systems are also a typical cause of penetrating damp. It is a very common problem found within older properties that have solid walls, newer properties tend to have much more protection from penetrating damp through the use of cavity walls and the way they are built these days, therefore new builds are less likely to suffer from this type of damp problem, although situations can arise in modern building.

Installed Kair Flat Ventilation System, “Work was carried out efficiently and neatly and clearly every effort had been made to clean up afterwards. The work took longer than scheduled - into second day - due to difficulty boring holes through re-inforced concrete (not anticipated) but this did not inconvenience me as flat is unoccupied at present. Allround a very friendly and helpful workforce. Very satisfied with outcome and would recommend this firm.”

Fixing a damp problem and re-plastering, “We had a damp problem in our hallway and a number of contractors looked and quoted for the work. Top Joints were the only company to properly look into what had caused the problem and did not automatically assume we had rising damp (old house, no DPC). It turns out a leaking stop cock was causing a localised problem, yet everyone else tried to sell us a DPC. Once the real problem had been identified, Top Joints' quote and plan of remedial action was very competitive and we were happy to give them the work. Everyone we dealt with was courteous and polite and queries were responded to quickly and professionally. I would recommend Top Joints.”

Disruption was minimal despite working in three separate rooms and the loft. This included cutting through three ceilings and fitting inlet and outlet vents through external walls. Kept informed of progress during the day. Quickly resolved small technical issue after installation. Would thoroughly recommend this company..”
