not realising the extent of the blockage problem, your plumbers were quick ti identify where we had damaged 50yr old pipes, what was needed to get to them, the extent of the damage, how long it would be to fix it, and the price it cost. they kept us appraises throughout the opperation of what was being done and the costing involved. they put in extra access point for future use and tidied up after themselves in a very professional way. much obliged to their prompt service
