Jet Stream Drainage turned out to be a great disappointment for us. The work was to dig up 1 meter of external drainage, and relay it with proper slope so that 5 meters is underground. Reconnections of the PVC piping at both ends, new piping for the length, two new access covers, and covering the dug-up area with simple stone. £1200 They quoted labour at £740 for what was explained to be easily one day of work two guys, with no special machinery or equipment.(Parts were an additional £460). When questioned(politely and very cautiously) about the possibility of changing the labour to straight-time rates(£480/day) the response was, I think you’d be better off calling someone else I cannot recommend this company.
