Damp - hopefully successful steps to banishing my problem

Postby Bezmonduk » Sat May 12, 2007 2:01 pm

Hi All, I have recently moved into my first home and now problems are starting to appear - the house was newly plastered/decorated before I moved in, after a few weeks I noticed several patches of damp in the bedroom ceiling - went into attic and the roof was leaking in several places - I have reslated the roof/replaced the flashing - which got that sorted, but now dampness is coming through the front wall and an adjoining wall - so next to do is replace guttering and possibly down pipes as I have been though the damp check lists and it seems to be combination of rising and penetrating damp.
The question is - after replacing guttering how long do I have to wait before I see any improvement (if any) as I do not want to replaster over a still damp wall.
If this does not resolve my problem then I will try applying either Ultra Proof waterproofer or Enviroseal to my external walls - as they still allow excess moisture to evaporate?
Lastly - due to money/time constraints I will go for a DPC

Does this sound like the logical order in which to progress things?

Simply Build It

Sounds good. See our project on waterproofing external masonry for some fantastic products which allow the walls to breathe.

Saturated masonry takes about a month for an inch (25mm) to dry out so leave it a while before making a decision although it should not get any more damp of course.

Thanks for the reply - sorry for not getting back - 'internet' problems at home.
Once my guttering is done, in next couple of weeks hopefully (been let down a few times) I'll wait about a month to see if there is any improvements.

Hi Bezmonduk,

I am not sure if you tried the water repellant products you mentioned, but I would be keen to get your views on them.

We have a brick wall that used to be rendered, the render has been removed and the bricks are damaged. The options seem to be rebuild the wall, re-render it, or clean it up and use a repellant product. Most people I speak to are against the use of a repellant product and are advising either of the first options.

If you did use the repellant, where did you purchase it from? I can't seem to find a retailer.

Your views/experience would be appreciated.
