Building Forum > Condensation on the walls
Hello Becky,
If you are only replacing single glazed with double glazed then this may even worsen your problem if it is condensation. Think about it like this - moisture is generated within the home by heating , cooking and breathing etc , the best thing to happen to the excess moisture is for good ventilation to remove it from within the home before it settles (although even with good ventilation inevitably some will condense on cold surfaces) . If your single glazed window is colder than the walls then most condensation will go onto the window but if that window is replaced with a double glazed unit ( ie is a better insulator) then it may mean more moisture goes on the walls instead . The key to all of this is good ventilation - (although I would definately suggest that your home probably could do with improved insulation in the walls and roof if practical as this will help). You should consider what ventilation you currently have ( eg airbricks etc) . If it were me I would insist on trickle vents being fitted to all the new windows. by having the vents open all the time ( they would be at the top of the frame ) this creates a gentle circulation of air through the property and this should help. Another suggestion is to use a dehumidifier daily but this is often costly to run and noisy.

do you have extractor fans in your kitchen and bathroom? if you have cavity walls then insulating them would help as it will keep the internal wall surface warmer and so reduce the likelihood of the water vapour condensing

Hey, thanks for the reply. I don't have an extractor fan in any of the rooms. I have found out some news over the weekend since fitting the windows. coach house - top half is render and bottom half brick; however the laying of the bricks under the render wasn't done to a high standard (as per our neighbours). The bricks in quite a lot of places have not been cemented vertical only horizontal; therefore this is causing a large draft (which we found out when the windows were being fitted).
Our neighbours believe the cavity walling is the only way to solve this problem, would this solve the issue? The walls are very called at the front of the house as they get little sun and get most of the wind hitting them due to the position of the house!
The loft has been done and is approx 8inch / 10inch thick

Hello,
I have a coach house and currently it has single glazzed windows at the mo.
We have new windows being fitted this month, but currently we have had issues with what i have been told is condensation.
The wall that our head board sits against along the bottom of the wall we had/have mould and every morning the walling is wet, like condensation. We have to wipe the walls down every morning to stop the mould getting any worse.
We also found the same problem in our living room now behind some bookcase, but no mould just the walls are very wet and the same problem in the bathroom. All the walls the condensation/water is on are the outside walls.
I have been told that when we got our new windows in the problem will stop however i'm not so sure....
all the outside walls are very cold however we don't have the problem in all the rooms
the coach house is approx 25 years old and doesn't have cavity wall insulation and is brick half way up and render at the top!
Please can someone help?
Would cavity wall insulation help......will it stop when the new windows are fitted.....???
