We had 2 storm water pipes that needed to be cleared every 2 years. After being flooded for the 3rd time we decided to bite the bullet and get the pipes relined. One goes under the concrete driveway and the other is 2.5 metres under a raised garden bed with a retaining wall so access via traditional methods would be hard.
All our dealings with The Drain Man staff were of the highest order. We dealt with a number of people over the 10 day project and all were professional, courteous and more than happy to explain everything they were doing as the job progressed.
As the pipes are blocked while the resin cures they checked the weather radar each morning before commencing work and on the one occasion when they couldn't work they rang to say they wouldn't be here that day. When one of the pipes was being cured and a few showers hit they rang 3 times within 3 hours to check that we weren't having any water problems with the rain. Also left a mobile number so they could return quickly if we did have any problems.
Overall we would absolutely recommend The Drain Man, not cheap, but you get what you pay for an excellent profession, through and courteous job.
