Need someone to have a look to quote
Waterproofing has been done, but water is still leaking . I request repair of roof and waterproofing done
Need My Tiled roof sealed asap
Damp rising in outside walls of 3 ground floor units
I have an open balcony on top of a concrete slab. Under the balcony is my scullery as well as a bedroom. Between the tiled floor and the wall around the balcony, water is leaking into the scullery and bedroom. The leaks are only just where the roof and the wall meets, not any other places on the roof. In the corner of the bedroom you can also see the damp on the wall, just opposite the one outlet of the water on the balcony.
