“Installed a utility sink in our laundry room, very helpful and fairly priced compared to other quotes. The best part is they have drywall options so you don’t have to hire multiple folks. They were also readily available when we needed them. Really enjoyed working with them!”

“The workers were great, the communication, the attention to detail and friendliness exceeded expectations. Gave us a quote and stood by it, no trying to upsell or upcharge. We needed our water lines to be dug down deeper than they were. They were clean, on time and walked us through step by step along the way. The guys were so professional, knowledgeable and helpful. Would highly recommend and will definitely be calling them again for any future services!”

Would highly recommend and would love to work with them again with any future needs!”

Most companies would’ve just told me to schedule a service call, but he genuinely wanted to help me get it done myself. Really appreciate that. Solid company and even better people.”

“*Edited 5/27/26: Following up on my previous experience, Garrett’s plumbing recently helped me with an unrelated broken tub valve. Their response time was excellent, and having an in-house tile expert made the repair process stress-free. Their family-owned team is not only professional but incredibly kind, they even fixed a stubborn front door for me while they were here. I stand by the fact that they are reliable, kind, multi-talented pros. I can’t recommend this team enough! After a pipe broke during an outdoor spigot repair and started flooding our bedroom, I was in a total panic. I called, and spoke with the owner of the company, who had his son Donald arrive at my house within an hour. He fixed the break incredibly fast and charged a very fair price for the emergency visit. Beyond the plumbing repair, he also referred me to a water mitigation expert who showed up within the hour as well. They walked me through the entire restoration process, which really helped put my mind at ease during a stressful situation. If you need a plumber who is fast, honest, and has a great network of professionals to help with the aftermath, this is the one to call! 5 stars.”

“Garrett’s plumbing is a great company for any of your plumbing needs! I had Ronnie and his crew remove my old cast iron and replace it with PVC. He was very honest and transparent about pricing and went above and beyond with the service and workmanship. He also did the top out and worked with my roofing contractor to get everything all sealed up properly. He also installed a nice water softener to keep us healthy with filtered water. I would refer and encourage anyone else to Garrett’s plumbing. They are a very nice personal family operated company. Thanks for all your help Ronnie and the team you did a fantastic job!”

“Had an amazing experience with Garrett’s plumbing! Donald did a spectacular job of replacing our old water heater. Everything was smooth, fast, and well communicated. They even cleaned up afterwords. Highly recommend this family business!”

“Donald truly came to the rescue! Great attitude and very thorough on his explanation of the issue. Would highly recommend his service again!”

“Great plumbing experience! Best service I’ve ever had honestly! Doesn’t bs you and is great on price!”
