What's causing paint on interior walls to bubble since heavy rain

bells_on_it

Hi I'm after advice as I've only loved in my house 4 months.

I decorated my dining room recently using good quality paints (valspar premium and dulux endurance), the walls were clean and dry before I started bit now areas of the pain is bubbling.

Its only on the exterior wall side and the interior walls are fine. Also some staining had come through on the same wall inside on the first floor. It's been brought on by this awful rain we've been having and I don't know what to do? Is it caused by the weather therefore covered by my buildings insurance or is it something else that I need to remedy?

Any advice would be great

Thanks

Should have added that when the rain subsides the bubbles do also but then when its starts pelting at it again the bubbles get bigger

You need to have a look at the outside of your house for a cause. It sounds like it's going to be some type of water ingress. Is this house new to you?

Yes we've lived here 4 months though its an old house built in 1905. I've never heard of water ingress? Is it serious? The house is stone brick, and then its painted (bit of a shame)

Could it be sweat then?

I'd check the wall outside for obvious dampness and possible water sources. Is the guttering leaking on to it? Is the soil level above the damp proof course? Is the mortar damaged? Next time it rains heavily get out there and see what's happening. Also, when it stops (I know, not often at the moment!) check regularly as the wall dries out and look for anywhere that's remaining damp for longer. This helped me track down a problem one time as it led me to the area which had an otherwise fairly well hidden fault.

Hi

I have same problem as yours, walls on first floor look a little wet with very small and light moisture patches on the inside. I went outside and the bricks look darker as compared to the rest of the house.
I bought a dehumidifier and that has helped the patches as well but I know the rain outside will keep spoiling the wall.
I am waiting that rain stops for a few days.
I have got water seal and once the rains stops I will put a coat or two of that on bricks outside and see if that helps.
I got a clear water seal, I will try it on a small part of wall first and then do rest of it.

you will need to find out why the look a differenet colour seal it in will only cause more problems

Hi

They just look darker i think coz of rain water. The remaining bricks look light and drier. The reason is that mine is a semi detached property and the property next to me starts about a meter behind my house so the front part of my property is exposed to rain water more than the remaining part of the buildin.

My house is stone but its painted therefore I can't see the bricks?? I'm wondering if the paint work is failing though and allowing rain through
