“James offered to stay and help me fix some things outside of a normal water heater install process, so that I wouldn't have to do it myself and reschedule the install date.”
“This company was very responsive, quick, and had reasonable prices that they were very transparent about. Stephen came out to assess and then replace my water heater. He didn't try to upsale me unnecessary stuff. Its refreshing to see companies that still do honest work at great prices. Same day service!”

When the tech Allan finally reached out, he asked if I still wanted him to come. I said yes, and throughout our conversation he asked me three times if I wanted to reschedule — making it clear he had no interest in making the trip. I went ahead and cancelled. If this …”
Positive
“We had a leak at the floor on one of out toilets. Since we had been discussing replacing them for nearly a year, we decided this was the right time to do so. Called Dial One, we've been using them for years, to give us a quote on 2 replacement purchases and installation. The tech came on Friday, gave us a quote for everything we wanted, and said he could deliver on Tuesday. On Tuesday he and another tech came and …”
“We had a toilet repaired and it works great. Also, we had Steven and Ashton install a new bathroom cabinet and faucet. It looks great and they did a good job.”
