The most common external property problems are caused by mother nature some visible and some not. Internal problems such as damp might not be visible and could be hiding away in the cavity wall.



Spalling is caused when water is absorbed into brickwork and freezes. This causes the water to expand as it ices, putting pressure on the masonry.

rising damp


Damp is caused by the cavity wall insulation creating a bridge allowing the water to pass through to the inside of the home allowing fungi to grow.



Efflorescence is the formation of white crystalling on the face of bricks. This is casued by excessive amounts of moisture within the wall.



Cracks are mainly caused by water corrosion slowly washing away the cement and freezing temperatures causing the water to expand.

Moss is commonly found on the roof of properties, but can also be found on brickwork. This is caused by porous masonry holding water.
