Honesty, integrity, reliability, professionalism, genuine customer service, consumer education - these are the reasons that I keep using Drainworks for jobs large and small - from $6-8000 excavation in 2006-07 to plumbing job under my bathroom sink in 2011. If Drainworks makes an appointment, they arrive on time or call if they have been delayed. They are courteous and respectful of my house, my pets, my time, and me. They are knowledgeable and always explain things to me so that I can understand what the problem is, what it will take to fix the problem, and the cost, so I can make an informed decision about what to do. I live a house that is over 100 years old where the plumbing is not new. Since Drainworks replaced the drainage system under my house in 2006/07 by excavating under the foundation of my house, I have not had any problems with sewer backups or tree roots. What a relief that I don't have to be worried about a wet basement every time it rains. I also use Drainworks for simple problems like a slow-moving drain under my bathroom sink when baking soda and vinegar no longer solve the problem. But what I like most of all about Drainworks is that they listen to my concerns and respond to them with good old-fashioned customer service, whether it is a toilet that needs a shim or an old gasket that needs TLC or a mysterious slow drip that appeared after a snaking job. There is a good reason that I am loyal to Drainworks - they have earned my respect. When I pay Drainworks to resolve a plumbing issue, they do it right and they leave me a very satisfied customer.
