Many people may find themselves battling damp when the weather turns cooler, and if you were already living in a house with a damp problem the recent weather may have made you feel that you were fighting a losing battle.
Damp tends to show up in ‘cold spots’ in houses, though this name may feel quite euphemistic if you have a bad case of damp in your home. Cold spots may be particular points on external walls that they get so cold that any moisture can form condensation, that leads to damp.
What leads to these patches? Well any of the following:
Hygroscopic Salts: These appear like tiny salt gains on your wall. They are actually caused by damaged plaster and can built up to create white staining, or a raised, crunchy salt deposit. These attract more moisture than non-damaged plaster, and can cause damp problems.
Rusty or cracked wall tiles: Gaps between the tile and the wall can harbour damp, which can eventually cause tiles to crack and fall off, as well as a general damp problem in the wall.
Poor weather proofing: Bricks are weather proofed to last for a certain amount of time. Old brick on Victorian properties may have worn down or had the showing faces blown off them, which can allow damp to penetrate and cause a damp problem.
