Testimonials

On 6/6/2026 Romero Lewis had this to say:
It is such a relief to have a plumbing company that I can trust unconditionally. Since purchasing an older home more than five years ago, I’ve relied on Cousin’s Plumbing for everything from routine maintenance to complex troubleshooting and emergency repairs. Throughout that time, they have never let me down. Their honesty, expertise, and professionalism are second to none. When critical repairs arise, their response is always timely, and their pricing has consistently been fair and reasonable. Todd, Johnny, and Hunter are exceptionally skilled, knowledgeable, and dedicated to finding the right solution. Brittany, who handles customer service, is always warm, friendly, and accommodating—especially when we’re dealing with a plumbing crisis. Her compassion and responsiveness make a stressful situation much easier to navigate. It’s rare to find a company that combines technical excellence with outstanding customer service, but Cousin’s Plumbing does exactly that. I highly recommend them to anyone looking for reliable, trustworthy, and professional plumbing services.

Excellent service! I called this morning and they arrived an hour later. It’s below zero with the wind chill and I’m on a crawl. My shower would not shut off. It ran all night. I couldn’t shut the main off because I was worried my pipes would freeze. Turns out I needed a new valve. That was replaced. He helped with my furnace as well. Very nice gentleman. I’m very pleased. He came recommended by quite a few friends too. So, I wouldn’t think twice about giving them a call. 💯 % recommend!
