how do i treat the first signs of rising damp ?

Question

Just spotted some damp mouldy spots on a wall in my bedroom...

Answer 1

cover it with paint and sell up - always comes back

Answer 2

Well, you've started the right way to address it now.

err, don't ask in B&Q

I assume you've done the obvious and topped any water tracking up the outside such as walls, plants, paint, soil beds

How do you know its rising damp, could it be penetrative damp or condensation, i think so ?

And its a bedroom right. So, I'll take a guess that its upstairs so its not rising damp.

pentrative damp:
This comes hrough the wall. If your house is painted brick it could be that the wall cannot breath. either sandblast the paint off or repaint the outside to cover up and paint cracks. further room ventilation should be installed such a trickle vents in the wall or window.

Condensation:
(Often the most likely)
can happen if air cannot circulate around the cavity, leaving cold air spots in the wall. This can be curred by vents in the soffets or air bricks to the cavity.Extra room ventilation + trace heat will help

If its ground floor bedroom and you're sure its rising damp a good chemical injection will fix it, either via a hire shop yourself or via a builder/damp proofer. Either way its not that expensive to cure rising damp.

A builder can advise...no need to panic

Glad to help.

Answer 4

Getting an independent specialist surveyor who really knows what he is doing is really quite difficult .There are so many things it could be from condensation to cold bridging to hygroscopic salts on a chimney breast.
One thing for certain, if your bedroom IS upstairs, is that you can rule out rising damp.

Answer 5

need more information, is it a bungalow? or if a house is your bedroom on ground floor ? Age of house and what type of DPC (damp proof course - slate or membrane ?
If your bedroom is upstairs it is unlikely that the problem is rising damp.

Answer 6

use damp proofing and water arresting treatment in the affected area. no other solution.
