"Abdiel was super to work with. He really knew his stuff and explained so many things to me that I did not know before. He gave me such a great deal that i couldn't say no. The system is perfect and the water delightful. Lucian installed the system. Couldn't have asked for anyone more gentlemanly. Very meticulous about his work. Seems to be a great company all around."

"We have used Rabb for years. Our old filter system needed replacing. Jodi in the Warsaw office was great. Helped us with details of what was needed and helped us with pricing. Eddie came and did the installation. He was efficient, knowledgeable and very kind. Thank you Rabb for making this an easy experience."

At PG Plumbing we have a simple yet powerful reason for starting our plumbing company: to bring a breath of fresh air to the plumbing industry in Fort Wayne and Allen County.\n\nWith the rise of large corporate plumbing conglomerates, we noticed the disappearance of the small, locally-owned plumbing businesses that once thrived in our community. This inspired us to step in and make a difference.\n\nOur mission is clear: we are here to provide our customers with cost-effective, personal experiences rather than prioritizing profit margins. We understand the frustration that often comes with plumbing issues, and our goal is to alleviate that stress with a service you can trust.\n\nWe invite you to choose PG Plumbing a local, employee-owned, reliable, and trustworthy team, for all your plumbing needs. Your satisfaction is our priority, and we are committed to providing you with the best service possible. Thank you for considering us as your plumbing partner in Fort Wayne.

"Chance's work on the plumbing we needed done was excellent-- he was punctual, communicative, polite, professional as well as how the replacements of the many pipes and fixtures were executed. He was able to effectively troubleshoot the issues that arose when coordinating with the city utilities, taking initiative when I ran into a conflict. He also was willing to work with our schedule and went above and beyond our expectations. Highly recommend."

"We signed the contract at the end of September and the project was started on December 3, 2020. It took them 10 working days to get everything completed (except for the glass doors). O'Neill glass measured for the glass doors on December 18 and they were installed on January 8. The shower is perfect and we love the flooring and new sink and counter. The shower is 5' and has a bench at the one end. Matt did a wonderful job and was so professional and so precise with everything. He put down the flooring as well as doing the tile work, installing the counter and sink, and doing all the plumbing. We couldn't have asked for a better company to work with. Steve Neeley, the owner, answered text messages promptly and was patient with us as we asked questions. Thank you so much, Serenity Kitchen and Bath and to Matt who did the work!"

"Nick and Pete came out, and their estimate was much lower than the others we received. Pete came out and got to work, even working on Saturday to complete the project! Our brand new shower is beautiful and functional. We’re very happy with this project, and plan on working with them in the future. Thanks!"
