“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.

It was great—they were very efficient, they came very quickly, they cleaned up, and when they were done, everything was fine. It was plumbing—may have been the bathroom sink. The bathroom sink was clogged up and wasn't going down the way it was supposed to. Everything's fine now.

I had a clog in the drain going out to the street, and I needed Donnelly's to unclog it. They came out quickly, and they undid the clog, and my drains run freely. They also gave me some other things—they sold me some other things to continuously keep my drains clean. Everything has worked so far. Based off of my experience with them, I would recommend them to others.

I had a sink that was stopped up. They were able to correct that for me immediately. They did a great job. They came out quickly for me. I would use them again.

I had a positive experience with Donnelly's Plumbing. We had a plumbing backup in the main drain. I think they did a very thorough job. What stood out about their services was just really good customer service—just really friendly, they explained every detail, and they contacted me back quickly when I called them. They were very responsive. I would give them an A.
