Their plumbers and technicians are incredibly personable and professional. They call ahead to let you know they’re on the way, which I really appreciate, and you don't mind having them in your house - take off their boots, mindful of your space, and they don't swear or use foul language. When they arrive, they quickly diagnose the problem and explain what’s going on. They seem honest and knowledgeable, and in our experience they fix the issue. They also provide helpful suggestions on how to properly maintain your plumbing systems to avoid future problems. Overall, a very positive experience. I highly recommend Clow Darling to anyone looking for reliable, friendly, and professional plumbing services! (I'm out of town, on septic and well) ⭐⭐⭐⭐⭐

I had a time sensative issue and called Clow Darling for assistance. After speaking to the after hours receptionist, they said someone would call me shortly. Within a few minutes, Nathan Steward gave me a call and gave me a suggestion that I had overseen. It worked and saved me a lot of stress. Thank you so much! I would highly reccommend!

I've had no heat for 2 days, it's very cold. I keep being told all their techs are busy with schools and apartment buildings that don't have heat, that no one is talking about on social media for some reason. I hear they used to prioritize No Heat calls and at least drop off a floor heater if they couldn't make it. Do not call Clow in an emergency.

I had an issue where it started with a timer not flushing. a block in the sewage. And the water was flowing back causing an unfortunate mess. when I explained the severity of the situation to Armondo on the phone. He was so kind and understanding and acknowledged my frustration and fear. He was able to get Devin and Truck out to fix my problem. My problem is fixed I think. And I am happy. I also got a water heater installed. Phil was polite and probably the best tech I have encountered with so far. He even sent a texted video to my husband when they were done so I did not have to try and explain things to my husband later.

Scheduled an appnt for a furnace inspection for Oct 6 as we had purchased a new house. Waited two hrs past the scheduled appnt time, tech was a no show. Called to inquire and left a message with “Joan”, the person I originally spoke with. A week has gone by and no response. Horrible customer service and communication. I will absolutely be looking elsewhere for a new hvac system and any further service.
