St Paul Pipeworks called me back after I searched and searched for a plumber and could not find one. Two of their technicians came out to inspect my gas lines and replaced them. They took their time ensuring that the job was done correctly. They stayed to ensure that the boiler and everything else worked properly. Because they do not deal with carbon monoxide issues, they left us with a strong message to get someone in to test for that, which we did. They care! They went the extra mile with their time and generosity, giving me the needed attention that this type of job required as well as giving me a double discount! This was a "big" job, a very expensive job and they came through for me remarkably! I use St Paul Pipeworks all the time and I recommend that you do as well!
