What is Penetrating Damp
Penetrating damp is the process of moisture moving from the exterior wall of a building to the interior. It occurs when outside moisture, like wind-driven rain, impacts a building’s wall. Building materials like brick are porous. They soak up rain to saturate the wall with penetrating damp
Defective External Porous Areas
Penetrating damp is a common problem faced by property owners and is caused by many known issues, such as leaky pipes, cracked external walls and damaged roofs and masonry.
Difference between Rising & Penetrating Damp
Unlike rising damp that starts from the ground up, penetrating damp can occur at any level of the building, including ceilings, floors and walls, and usually gets visibly worse at certain times, like during wet weather.
Moisture & Rainwater
Penetrating damp and or water ingress, is a type of damp problem that is the result of moisture or rainwater successfully penetrating through to the internal wall from outside of the property.

What causes Penetrating Damp
Penetrating damp is a type of dampness that occurs when water infiltrates a building from the outside due to structural issues. It usually affects walls, ceilings, floors and door and window frames are caused by water seeping through porous materials like brick, concrete, or stone.
Damaged Brickwork or Masonry
Cracks or degraded mortar allow water to enter.
Damage Drains & Pipes
Cracked drains & pipes can lead to to penetrating damp.
Faulty Roofing
Broken or missing roof tiles, damaged flashing, or leaking gutters.
Defective Doors & Windows
Door & window frames that are not properly sealed or the sealant is no longer effective.
Defective Render or Cladding
If external coatings deteriorate, water can seep in.
High Ground Levels
Water can seep through walls if external ground levels are too high
Defective External Surroundings
If the external walls are not kept in tip-top condition they can become a cause of penetrating damp problems. The walls can lose there ability to with stand the elements and can allow moisture to penetrate through to the internal walls of the property. This problem will increase the longer the walls are left in that condition. Contact us for a free on-site consultation to have your penetrating damp problems assessed by our engineer.

Cracked Porous Concrete
If concrete around your house becomes porous water can penetrate the concrete and penetrate deeply through to the inside of the property. The more the property is subjected to rainfall the worse the problem will become leading to unsightly damp patches appearing on internal walls which will grow in size during periods of heavy rainfall as more water penetrates.
Defective Doors & Windows
Gaps and cracks around window and door frames are common problems that, if ignored, can lead to damp and moisture.
Defective Rendering
A broken pipe on an external wall is a common cause of penetrating damp, as water continuously seeps into the structure.
Uneven Ground Level
Penetrating moisture can also be seen where external ground levels are higher than internal floors, or where damp-proof membranes to concrete ground floors are faulty causing external concrete damage
Damaged Drains
Damaged and cracked drains around a property are one of the leading causes of damp, mould, and wet rot in a home. Broken drains can also cause water to fall or collect in irregular areas and cause dampness and mould growth.
Repaired External Drain
Roof Damage
Water ingress on roofs can lead to mould, mildew and algae, causing penetrating damp and expensive repairs. Roof damage can let in moisture, causing damp to take hold.
Repairing and Preventing Penetrating Damp
The best way to ensure penetrating damp does not damage your property is to take preventative measures. Regular guttering, downpipe, roof and window, concrete and rendering maintenance will help to defend the home from dampness before it sets in. Checking renders and sealants regularly for early signs of damage also stops moisture ingress.
