"This has been the most frustrating experience in my life. They said the project would take a day and a half. It has been 2 weeks and there is NO end in sight. They do not believe in keeping the customer informed about the status of the project. They say "somebody will contact you- but nobody does. They left the work site in an unsafe condition. Repeated request to remedy the situation have been ignored. First and last time user of Angie's services. I am non verbal. NO PHONE CALLS. I want to see someone in person ."

We're dedicated to providing our clients with the very best in service, installation, and repair for all phases of your plumbing needs. We specialize in a variety of residential and commercial services and take pride in the attention to detail put into each of the projects we're involved with. We're known for our quality work and the integrity of our business. We look forward to building long-term relationships with our clients, and guarantee your satisfaction.

"Last year Reliant performed a repair on our wastewater line which broke under our garage. It broke this year and they refused to cover their previous work trying to blame the city and our foundation. We have had recent foundation issues - because of the leak under our garage causing soil heaving! They ghosted us after it became clear that their previous work was the issue. Another plumber (Blue Ribbon, 5-stars!) did a much better repair but cannot fill the 5' deep hole under our garage because Reliant never closed the permit from last year. They also did not install all parts listed in the invoice we paid, yet still claim they are not at fault for the current issue. The timeline is now nearly 6 weeks since the current issue began with no issue in sight. I have repeatedly asked for updates and better communication, yet I am the one who always calls them. Regular people cannot be expected to be plumbing experts. We relied on this company to operate in good faith. They have not."

"I really needed my outside faucet replaced, it was not working properly and was very hard to turn off, to prevent leaking. I called Excalibur Plumbing and they sent Curtis out to fix my issue. He was very friendly, courteous and easy to work with. I use this faucet a lot in the summer time to water my flower bed and my yard. It's now working better than ever! Thanks Curtis!"
