We have used St Paul Pipeworks on a couple of occasions and they are a good plumbing company. They are immediately responsive when we need them and they have a very good knowledge about a wide range of plumbing issues. They have been able to solve a couple of problems for us that previous plumbers could not solve. We had an antique drum trap in the basement, for example, and it was dicey as to whether or not it could be repaired. But they managed to get it fixed and now it is working perfectly. They also just repaired a valve in the shower for us - the one that causes the water to go up to the shower head. Now, that is working perfectly too. They are very honest people about what they can and can not do and we really appreciate that. They do not oversell themselves. They do good work and I have been recommending them to people I know!
