We had to relocate and install new sprinklers in our retail shop. I found J.R. Wagner Fire Protection on YELP and decided to call base on the reviews. I am so glad that I did! I cannot say enough about Jon & his team. Jon made sure he met our deadline. He kept me inform step by step. He was honest! He completed the job in one and a half day vs a week quoted by another company. His team was there for inspection and took care of a preventative issue. Then Jon attended the final inspection. The whole experience exceeded my expectations!!

I had to get a leaking fire sprinkler head replaced in my home. I was pleasantly surprised when Jon answered my call late on a Friday evening He asked me to text him a picture of the leaking head, and immediately alerted me to the fact that it was a defective and recalled sprinkler head. Jon is extremely knowledgeable and recommended the right replacement heads, provided a very reasonable quote, and scheduled the job on short notice. Chad and his helper from J.R. Wagner came over on-time on a Friday, were super efficient, super professional, and got all the work done smoothly. My wife and I are very happy that we came across J.R. Wagner Fire Protection. I would highly recommend Jon and his team for any fire protection related work.

We had a problem with our hydrants testing correctly with another company so we decided to get a second opinion. J.R. Wagner came out immediately, performed the test correctly, and thankfully, our hydrants passed without any issues. We will be using J.R. Wagner from now on, and we highly recommend them!!

We had a burst fire sprinkler pipe in a brand new home we had just moved into right after the New Years holiday. They sent out a technician on a Sunday night who was able to repair the hole in the pipe and test the system so we could return water to the house before the next day. We had called around so many places and either they wouldn’t come out on a Sunday, they didn’t do residential, or they wanted a minimum of 24-48 hours of the water being off. This company was extremely professional and was able to help us out with a minimum of inconvenience. Donny the technician was very polite and courteous and really saved the day. They do charge an emergency rate for off hours but who doesn’t. If I ever had trouble with my sprinklers again, this would be the first place I would call. I would highly recommend them.
