I had a new bathroom fitted early this year. Part of the job included supply (by the bathroom fitter) and fitting of a new extractor fan in the bathroom.
6/7 months later the extractor fan has stopped working (and the insides filled with water - so it was completely broken - needed a replacement). 12 month guarantee on the work so I called out the original fitter, after originally (wrongly) blaming my roof, he went away and worked out it’s due to a condensation trap being needed between the fan and the ducting in the attic, and insulation needed on the fan ducting in the attic. He’d already been up there previously to fit the fan. (For some reason this hasn’t been an issue with my previous fan).
He fixed all this and fitted a new fan, and then once finished the work - stated he would be sending a bill of a couple of hundred (no quote beforehand for this work, so I assumed it would be covered as remedial work for the original job). This will include the cost of the new fan.
It’s not a huge amount, but I’m a bit annoyed this work wasn’t included/ suggested as part of the original job (especially as a quick search online states this is recommended with any fan installation so I would expect a bathroom installer to know) and now I’m yet again paying for a new fan. I would have been more than happy to pay for the insulation/ condensation trap materials as part of the original job if I knew without it the fan could break in a few months.
I tend to be the type of person who just tend to go along with this kind of stuff (and have been taken advantage of in the past) - so wanted to get a sense check, does this extra cost seem reasonable? I already know the fact he didn’t quote this before doing the work is completely unacceptable (though I take the responsibility of not clarifying he considered it part of the guarantee).
