Take Our Clirent's Word For It

"I feel so grateful I came across Keether and his company. They are efficient, kind, and trustworthy. Keether promptly answered my call and saved the day. They will forever remain my go to people for any future problems. You can't go wrong with these guys!"

Olivia Hardt
"Keeth proved an exceptional plumber who I would hire again. He repaired a pipe leak in a tight crawl space underneath our house, replaced parts in one of our toilets to stop a leak and improved its efficiency, cleared a pipe blockage, and replaced bathroom sink parts to stop a leak. We’ve had no recurrent issues since he performed this work. Based on our experience with other plumbers, we found Keeth able to quickly diagnose and repair plumbing issues and consider ourselves fortunate to have hired him based on a referral from our neighbor who is a real estate agent."

Bob Garza
"I have had the pleasure having Keeth do work for us both at our restaurant and home. I was in the trades for 35 years and rare that I would be willing to refer so many tradesman, Keeth is one whom I love to refer. First and foremost it begins with integrity and he has integrity in spades. Principle plumbing has always been on time, never late which is rare along with quality work. Don’t hesitate and call now for a terrific plumber."

He is quick to ask for clarifications and not shy to recommend better options. He takes pride in his work which is not often experienced these days. Truly, he has been a joy to work with. I strongly recommend you use Keith for all you plumbing needs. You will be in good hands!!!!!!!"

"Keeth is absolutely amazing! He is hands down my number 1 plumber! Not only do I go to him for all the plumbing needs in my own house, I’m a Realtor and refer him to do the work in all of my clients’ homes! Always reliable, efficient, responsive and reasonably priced. Plus he’s a wonderful man and very enjoyable to work with!"

Keeth was on the ball and not only where their prices the best out of the 5 companies I asked for bids from, is service was a phenomenal and went above and beyond my expectations. I cannot say enough good things about this company and would definitely recommend them for any job, large or small."
