Does mould encourage more mould?

[linspins]

Help! I just can't keep on top of cleaning away mould in our house. It's really depressing me. We live in a normal 1930's semi, but mould keep springing up.. around window frames, round the kitchen door, up the walls in the (cold unheated damp) utility room etc. Recently I was mortified to find mould along behind the curtain rail in the living room and some on a wall in my son's bedroom. Upstairs, some of the edges of the ceiling curve down a little, and are obviously under-insulated, as condensation gathers there, although the rest of the ceiling is fine. We have recently got a tumble dryer, to help cut down on humidity in the house, and are waiting for a new kitchen with an extractor fan. I know I should open the windows more but it's been so cold.
Sorry for long post, my main question is this: if I clean away all the mould I can, but some gets left accidentally, does this mean mould will come back quicker because there is still some around? Or is there mould spores in the air anyway, everywhere? Does a tiny bit of mould in the house encourage more? Thanks all!

It will grow back slowly and yes at a certain stage it is air-born and not good for you, especially small children.

Can you identify the source and tackle that? There should also be some good anti-mould sprays out there to use, once you've cleaned the areas.

If it's the black spot type mould, then , no, I don't think its mere presence encourages more mould. The spores are, as you say, pretty much everywhere. It's the damp condition that encourages the mould to grow. It stops without damp. Though mould present will of course mean that there are more mould spores in the air.

If the mould is lines (not spots in a line, but actual lines), solid or ringed blotches, or 3-dimensional, then even the least bit left will regrow and just drying out the environment will not be enough to get rid of it.

Where are you? We've been opening our windows for at least a few hours every day for weeks now, and some days leave windows open a crack all day.

Yes mould does grow and spread. Here's what you need to do to get rid of it permanently:

(1) Use a spray mould remover.
(2) Buy some anti-mould sealant for your walls and use it - you will need quite a lot to do a good job, it needs to go everywhere.
(3) Increase heat and ventilation.
(4) Stop using the tumble drier until you have an extractor

I do use an anti -mould spray...it just seems to regrow so fast. Yurgh. And some of the window seals seem to have it permanently in them, not even bleach shifts the marks.

Whomovedmychoc, is that anti-mould-sealant a clear stuff you paint on? Is it matt or shiny, or a paint?
I am aiming to improve ventilation now that the weather isn't vile - and when summer finally comes and the walls are bone dry I will tackle them with the anti-mould sealant.
Thanks for the tips all. xx

You will find it very hard to find I'm afraid. Sometimes you can get hold of it from builders. A better bet is probably mould retardant paints which have an antifungicidal agent in.
