[i]Hi, Sorry if this sounds like a silly post but I am clueless when it comes to building work etc...
I was hoping someone could advise me about could any of the following cause damp and mold within a house structure please...
When I moved into my house in 2009 there were no problems internally but the external wall had a few cracks in it. Over time these cracks became what you see in the photographs below..
Around 2013.. Mold and damp began forming on the internal wall and no matter how many times I would clean it - it would return. Anyway long story short, after finally getting a massive overhaul to the outside and inside of the house at the end of 2018 - all the damp and mold had been sorted and gone.
Only, In Dec 2020 I had to stay in hosp with my daughter for 3/4 days (my other daughter was home) When i came home.. I was mortified to find my bathroom upstairs, landing window and downstairs toilet, area by the back door covered in black mold again.
I have since found out that when my new guttering was put on, the downpipe wasnt put on right so for the past 2 years, the rainwater was coming back in on itself and although the external wall is ok... There is a big gap between the bottom of the walls and the path.
Could the damp and mold problem be structural from when the wall had the gaping holes in it and could the downpipe and the outside gaps be causing it to? [/i]
