Plumber Job - Meyersdal, GP, 1448

Inspection carried out by others due to a water stain forming on the ceiling. An audio test was performed and visual inspection carried out. No pressure leak was detected, however the report concludes that the water damage on the ceiling has been caused by a faulty shower trap. My insurance does not cover this and the Contractor sent out to access the situation does not specialize in water trap repairs. I require a reputable Company that is accredited by the PIRB that is experienced in the above, with the necessary insurance in place to carry out the above as detailed.
