IRB waterproofing quote needed. Greetings to whom it may concern, I have a house with part of the roof being flat. The problem initially was the gutter connectors are to small for a large amount of water. Subsequently outlet avenues were made available as to alleviate the water buildup. I have had work done on the roof and recently had an assessor from outsurence asses the roof His recommendation is that a thorough waterproofing needs to be done as the waterproofing done last year is flaking and allowing some water to seep through. This needs to be sorted out and would request an assessment and quote in this regards.

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.

+- 50m2 - Durbigum OR Torch-on (ABE). Need a quote for the bill of quantity - hence there is no need to have people contact me. A Bill of Quantity is to establish costing. Once the client approves the estimate then an appointed contractor is informed. Pricing - includes material & labour. Draws are paid on progress and not a deposit - that tells me a contractor is not positioned financially - material on site is another matter altogether. See JCB for standard contractual info.
