Greg at GPS Plumbing is an incredibly dedicated master of his trade who truly loves his job. He has all the right knowledge and equipment to get the job done as quickly and efficiently as is possible. For me, he had to replace both sewer and water pipes from the street to under the slab in my house (in mid-January). As with many major plumbing jobs, problems were encountered, but none that Greg and his team couldn’t resolve. I don’t expect that I will ever have sewer issues ever again, but I’m glad that I now have GPS Plumbing in my phone book. Thanks Greg and team, you are highly recommended!

Greg is an excellent plumber! He is impressively knowledgeable and has efficiently resolved and/or repaired a variety of plumbing problems that we've experienced. He was also able to identify a location where we could install a (much needed) water conditioner and did so within a limited space. We would definitely recommend GSP Plumbing!
