Arguing with my husband because we seem to disagree.
We have been tenants in our flat for 3.5yrs. Never missed a rent payment, no noise problems, neighbours like us etc.
Landlord is lady who bought the flat from her son, our original landlord about 6 months into our first tenancy. She is often away in Spain and acts quite put out if we contact her for any repairs (we do this once or twice a year normally!)
Anyway, long story short as much as possible. We have had problems with dampness on the lounge carpet once before and she sent out the "handyman" she never sends an actual tradesman it's the same guy for everything. He said it was related to the boiler and done his thing and eventually it dried up.
Fast forward two weeks ago my husband resealed the bathroom sealant (he is not very good with DIY by his own admission) and now the damp patches in the lounge are back. He's convinced the two are connected.
I got a plumber out today and he said it's unlikely that's the reason it's probably the boiler or a pipe under the carpet.
The stain is getting worse and he thinks it's our responsibility to fix things! I think it's definitely the landlords and we haven't done anything wrong, we tried our best! He's worried she may try and evict us because of the damage 
he's a worrier bless him but it's starting to piss me off as it needs sorting and we don't have the money for plumbing work on a rented property!
