]Hi, please see pics below re damp problem. Anyone had this problem before. Can anyone recommend someone reasonably priced to fix this?

 

We've tried a dehumidifier but it doesn't work.

Unless there is a definite leak around the window, this is more likely a condensation issue. There is plenty that you can do without necessarily throwing money at it. There is plenty of info around the net, or you can contact me for a free fact sheet.

Solid wall house? A combination of condensation, lack of ventilation. Old solid wall house all sealed up, moisture created and condensation on a cold area of outside wall. There are ways to reduce this for example extractor fans in the kitchen and bathroom, condensing tumble dryer etc. Having some positive ventilation during the day while the house is empty will help. If possible windows slightly open and all the doors open so air gets around.

 

Do you have a cellar? And an attic? Air coming from the cellar vents working it's way around the house and exits by the Velux window trickle vent.

 

Another way but costs is fitting an Envirovent. Excellent for houses of multiple occupation.

Had some more thought over this? Is this a bay window? Check that you have a working drip on the outside sill. Also check the condition of the bricks and is the damp proof course working. Bay's are often built separate to the house and are 'loose' . The damp proof courses often fail and being 'loose' even and chemical dpc often fails.

 

Also check the outside pointing and the bricks for being frost damaged and porous.

Thanks for the replies and for handypandy sending me info. I'll have to keep and eye on it and see how it goes. Maybe a bigger dehumidifier is needed.

Whilst dehumidifiers are useful, they are not a solution and also have a downside. The primary issues with condensation are always heating, insulation and ventilation.

Now you know. Put some heat on and open windows. Get a tumble dryer as well. End of simple

.......and a CONDENSING tumble dryer, or one that can be permanently vented OUTSIDE.

 

(I knew a Muppet that vented indoors and blamed the landlord for condensation & mould.)
