Donnelly's was very good. I had a backed-up septic tank, and they used a machine to clean it out. I would give them an A+ because they did a good job.
The technicians from Donnelly's were on time and knowledgeable, and they did a good job as far as the quality of the work. They cleared a drainpipe for me and reconnected a sink. I chose them because of their responsiveness; I couldn't get a hold of some of the other guys. They get an A rating.
I liked the service tech who came out. I haven't had a problem since. I thought he was good, and I'd give him an A+ grade.
Donnelly's was great. They were honest with me about what the problem was, and they fixed it right the first time. I had an issue with my washing machine basin. The trap broke, and the drainage line was clogged. They were excellent.

We had a clog, so they cleaned out where the sewer cuts up through the ground and repaired that problem. It was just a clog—it didn't run over, thank goodness. They did a few other little plumbing jobs, but that's about all I had to have. They came here twice—very nice. I would give the top grade, A, and I would use this company in the future.

My experience with Donnelly's Plumbing, Heating, & Cooling was extremely positive. What was so positive, what I appreciated, was they were very forthcoming and were able to give us the information we needed in order to fix our problem. They did work for us. They cleaned out some sewer lines. We would give them an A.

I can tell you this much, they've always done good work for us. I can't recall exactly what they did, but I didn't have any problems with their service at all. We've had some plumbing issues, and I'm pretty sure that they were out here to take care of plumbing issues in terms of backed up drain pipes and stuff like that. I think they've done a very good job. They might have been here since then also. I would call them again if I had any plumbing issues or needs.

I've had Donnelly's Plumbing, I think twice. I know at least once, and they performed the job that I needed done expertly, professionally, and effectively. They opened a drain.

I've had them several times over the last couple years. I don't remember what it was—probably a blocked drain. They come right way; they're very prompt. The people who came were very nice, and they seemed very thorough. Good, quality work from them. I would recommend them to others.

We had a backed-up sewer. They responded immediately and did an excellent job. I would call on them again.
