    Derek did a great job and was very professional and courteous. Only concern is Donnelly’s pricing schedule.

    I was very pleased with Nick’s work. But, also with his explaining every detail of what he was going to do as well as some other important plumbing tips.

    Oct 2025 - Tony Reyes came out to do a hearing system inspection. He was professional and polite. He advised on 2 improvements which I put under consideration for later. I am gun shy now. Oct 2025 - they returned to correct the original plumbing issue and it was a quick solve which made me question my prior spend of $2k. Sept 2025 - I had a plumbing issue with a toilet and they came out and I ended up paying for $2k of repairs resulting from my subpar builder but was told it caused the issue I was having. All of the repairs however did not resolve my original issue. 😐 July 2025 - Justin Henry came out to perform an AC inspection. He was on-time, courteous, and thorough. I now know about possible upgrades I can add to my systems but also that my AC is good condition. Holding at 4 stars. March 2025: Joseph Garber came out for a plumbing inspection which is a covered service for the $20/monthly fee I pay. He was professional, personable, punctual and just nice. All of their service reps should have some of the “P”s listed above. Adjusted my review rating from 2 stars to 4 stars. Jan 2025: Horrible experience with the last service visit by Kevin McCullogh. He arrived without a service appointment while I was at work but my son was at home. My son let him in to do the work when he couldn’t reach me at work. The service was done well but it was an hot mess with the payment. I had to call the main office from work to make arrangements. All of this made my son late for his college class because none of it was planned. Not the experience I am used to. Disappointed and I am doubting using them for another service I was considering.

    The team of 3 that was here to replace my sewer line were extremely confident in what they were doing. They kept we well informed and worked very well as a professional team. They were polite and workmanship was wonderful. All was cleaned up before they left. I would definitely use this crew again no doubt. Give them 5 stars for sure.
