Damp Treatment | Everything You Should Know

Most Obvious Causes of Damp


There are many different causes of damp, here are some of the main causes;

Plumbing


Even the tiniest leak could set off a large-scale damp patch in your home.

 

Check for:

  • Corroded water pipes that are concealed in walls

  • New plumbing for central heating, kitchens and bathrooms that drip when first used

  • Failing waste pipes in older bathrooms

  • Damaged seals around baths and showers



Leaking Gutters


A leaking gutter can allow water to run directly onto the wall or splatter on window sills and the ground below. This type of moisture build-up can cause damp in your home.

Check for:

  • Splattering – from gutters splashing water onto walls

  • Tracks of water in the roof which may be following roof timbers for several feet



Holes in Roof


There probably isn’t going to be a massive gaping hole in your roof without you realising. But some of the tiles or slates may be missing, have slipped or have broken, leaving the roof exposed.


Undersized Gutters


Climate change, causing an increase in rain may be the reason that your gutter is too small. Either this or whoever installed it was incompetent or unaware of the required size. There may be an odd occasion when extremely heavy rain causes your gutter to overflow – but this should not be a regular occurrence.

Check for:

Water spilling over the edges of the gutters on a regular basis

 

Chimney Stacks and Roofs


It is very common for a chimney stack and the surrounding roof to have weak stops – especially if the property is old.

Check that:

  • Roofs and chimney stacks have watertight flashings

  • Chimney pots are fitted with rain caps


Downpipes


Older cast iron downpipes can rust easily. When this happens it will not always be obvious because the problems could be lying where it’s not visible.

Check for:

  • Holes in the back of a downpipe

  • Water spewing back out of the downpipe joints

  • Water tracking from the downpipe along brackets and to the face of the wall

Damp Treatment Options


If you do find damp, you need to arrange damp treatment immediately!

There are different methods of damp treatment available including;

  • Solvent-based systems

  • Aqueous systems

  • Gravity feed systems

  • Injection mortars

  • Injection creams

  • Electro-osmosis systems


Basic damp treatment procedures involve drilling a series of small holes in the wall and either inject or feed the product into the holes. The patterns of drilling and pressure used to administrate the injection will vary depending on the product.

Always hire a professional when it comes to damp treatment to ensure that the problem is resolved the first time around. A professional will also know which product is suitable for the situation.
