Hello.. I privately rent my house.. Soon after having new windows fitted mould started to appear at the top of the bathroom window after heavy rain.. We told our landlord and she said its from the shower.. Im not so sure as everytime it rains the wall starts to drip?? there was no problem before the heavy rain started.. its now been a few months Ive cleaned it numerous times and it comes back worse..
Who do i go to if she refused to find out whats causing it.. ?

It just looks like condensation.

should really have an extractor fan in a shower room or at least have tiled walls.

just open the window for 5 minutes after you shower

it will be from the shower I expect but the previous windows probably let in a lot of air so condensation didnt build up.

are you defo sure that it only came when new windows were fitted? and also you are 100% sure that it becomes wet when the weather is chucking it down? check for cracks on the outside/inside.

If you arent 100% sure on the both above, try after having a shower (or bath) ventilate the room (open windows/doors). Another possibility is that new windows created a better seal to the room thus keeping the moisture in.

3rdly it also depends where abouts you live, some areas generally have moisture than others.. my parents place is v v dry, as mine is v v moist.
#5
i would have thought your old windows allowed ventilation? so prob just condensation...do you have an extractor?
its a little worrying if it mainly happens after rain....i would tell the landlord again as its damaging her property?
#6
Good ventilation & some mould & mildew remover will do the trick.

I use a mould & mildew remover, cant remember who makes it but it's in a green bottle. It's amazing stuff, spray it, leave it on for half an hour & the mould has gone :thumbsup:

Okay, this is clearly a moisture problem, or rather a lack of ventilation.
I find that de-humidfying tablets work well, but really you need to circulate and remove moisture from the room.
Normal suggestions of leaving windows open after showers etc, but ideally you need a fan solution.
You can also buy mould resistant paint especially for these types of sceanrios.
However, unless the moisture in the air is dealt with the underlying problem will remain and water will still collect on the ceiling.

Really your landlord should be concerned about this and taking the necessary actions to ensure the air in your bathroom is of a reasonable quality.

Hope you get it sorted Steph,

im not a builder but have the windows been fitted incorectly? i mean a gap left so water is going into the cavity?
#9
You did mention it only happened after heavy rain. Is your guttering/overflow pipe clear?
#10
The window doesn't look as though it has a ventilation slot fitted either? That you can slide open and shut?
#11
black mould is condesation as it only grows on clean water vent as much as possible and when running bath etc
#12
If it starts dripping when it rains and you are not using or have recently used the shower then in is probably coming from outside. If you have been there for more than a couple of years and this only started soon after the new windows then it is probably bad fitting or damage caused while fitting.

Go outside and look for any way the water could get in. A crack or gap above or at the same height as the areas affected. Take pictures or better still a video of it when it is dripping. Try to show how it is connected to the rain.

If you don't sort it soon it may disappear again until next winter (unless we have another wet summer).


The landlord will save a lot of money if she deals with it quickly. If not joy with her then talk to citizens advice bureau.

We lived here for 3 months then the windows were fitted and there wasnt a speck of mould before that..
Im deffo sure its after rain as it has been dry for a while untill this week and the wetness appeared again it has rained heavily for days on end..
The door is left open when the shower is in use as after it appeared the shower made it worse..

I dont know.. i honestly think it was a crap job.. as we have cracks and mould around most of the windows.. (mould on these im pretty sure is from condensation as its only around the seals..

cant see how rain would make it worse unless the paint is bubbling up (i.e water penetration from the wall). If mould is just on the top of the wall paint, then its just a case of leaving your window open AFTER for 10 minutes and during a shower (and leave the bathroom door open at all times if possible)

Good point. Did the old windows have these?

If they did, I was told by a reputable window company that it was illegal to 'make the windows worse', if you get what I mean. IE - if the old windows had the ventilation slots on then legally, the new windows had to have the same ventilation.

If this is the case, it may be worth checking out.

if it was coming from outside, then the paint would be bubbling up and falling off

The old windows were single glazed .. (original windows from the 60s)
And no they didnt have vents.

from the 60s! :w00t:

loads of natural ventilation anyway then

just spray some bleach on it, clean it off, shower with window open and leave bathroom door open when you can

then see if it comes back
#26
lol thats clear condensation.........you need to air the room, every breath you take is gonna add to it

why have you let it build up so much without cleaning it?

open the vents on ur windows and open your windows for once..........YOU NEED AIR

you need a spray to kill the spores! else you are just moving the spores everywhere you put the cloth/sponge.

Just spray that dettol stuff above on it and leave it to do its job, open the window though as it stinks.

or save yourself £3 and just put thin bleach (about 8p for 2L) and water in a spray container. Works just as well in my experience. Bleach kills everything.

how you gonna rule out condensation exactly?:whistling:

if it comes back.....its not condensation.......i laughed

All your spores will be deep in the wall and once humid will come out and manifest as mould. Your landlady probably knew full well about it and gave it a good coat of paint before you moved in. Ideally you need to dry out the bathroom as much as possible and then treat, i guess the best time to do this would be over warmer months.

how have you come to that conclusion out of interest?

since it has only started happening since new windows have been put in according to the op........these new windows do not have ventilation in them like the old windows which they have replaced
#38

Time scale ....OP has been in the house for 3mths approx, so i'm sure the landlords would have given everywhere a lick of paint to make it look presentable to rent again so they wouldn't have noticed any mould growth. Just coincidence that windows were replaced and mould started growing again. Surely it would take a couple of months for things to appear again.
