During the recent storms I had a leak which stained the plasterboard quote badly. The leak was from the above roof/door of a balcony.
I'm convinced it's leaking under the door cill and down through the cavity wall onto the ceiling below. This is because it only seems to happen during heavy rain and wind.
The other possibility is it's coming in from the flat roof right at the top and dripping all the way down the cavity
It's a 3-story townhouse and there is no supporting wall for the balcony. It had 2 metal beams running the full width as support.
My house is out of the 2-year defect and I'm with Premier Guarantee. I'm not sure who I should call as without ripping the door out or roof it's very hard for anyone to give advice as to the cause.
Any ideas would be appreciated greatly
Problem one is that it is outside the 2-year warranty period when the housebuilder would be responsible for investigating and fixing. From what you have said, it would seem probable that the cause of the leak was evident on day one.
Problem two, is you have Premier Guarantee, the only "Guarantee" is that making a claim will be a long drawn out process and still cost you personally £1,000 even if they do proceed.
Problem three is I don't think you would be covered for insurance unless you can show it is a result of storm damage and even then they won't fix the latent defect.
I doubt very much the leak is being caused by the door alone. A new door would be unlikely to stop it. What you have done with sealant may help lessen the leakage short term.
From what you have said, it seems likely the leak is being cause either by a faulty of badly installed cavity tray or that no cavity trays exist at all. The plans should show if they were indicated on the working drawings. getting a copy of these again is another matter entirely as builders seldom provide them.
I must add that the Housing Association should be interested in ensuring their share of your property does not degenerate and I am surprised they are uncooperative in this respect. Especially so as one of their inspectors I suspect, would have checked your home throughout the build and on completion.
