I had to update my review to add how excellent John has been since the installation of the pressure relief valve. He made himself available to answer many questions I had following the installation which I appreciated very much and addressed additional concerns I had regarding mitigating any possible issues with the fire sprinkler system in the future. He was patient and provided his professional recommendations while allowing me to decide on any next steps. He talked me through all that was done after I decided to add a pressure regulator to the sprinkler system and let me know he is available should we have any additional questions, concerns or notice significant changes with the pressure. His customer service is top tier and I appreciate the service he provided and more importantly, peace of mind knowing there are measures in place to reduce the possibility of future issues. read more

I called a plumbing company to replace a leaking pressure reducing valve (black left) but the shutoff valve (silver right) got triggered after water was restored. It was stuck to providing water only to fire sprinkler but nothing inside the house. The person left without fixing it, since he said it is part of a fire sprinkler system that he is not licensed for . I called John the next day and he came the same day. He tried to reset the shutoff valve and tried to push down the stuck part but to no avail. He ordered the part and got it replaced. He is honest, professional, knowledgable and really care for his customer. read more

So thankful to God for guiding my husband to find John Harden and his company. John seems to be a very honest and professional individual. Even by phone he is courteous, making himself available when one calls. He is patient in listening and understanding inquiries, then is thorough in explaining. He gave an estimate over the phone and explained possible scenarios. John offered to come to my home earlier than originally scheduled. This was after working on another long overnight job with his crew. I appreciated him still showing up on time. He inspected the fire sprinkler head that had been leaking the week prior. I appreciated the knowledge and honesty he shared. He didn't want to over charge. He mentioned that he could return and thoroughly inspect the area once the ceiling was cut open. Honest hard working individuals need to be applauded and recognized for their honor and integrity. My plumber came out & cut open the ceiling. John Harden was nice enough to take the call and communicate with my plumber and come to a conclusion. John Harden came back and inspected thoroughly. Helped me find out that our RainDial controller wasn't working properly. He also showed me the pressure build up on the fire sprinkler gauge before turning on and off the water sprinklers for the yard. He explained the process of static build up. John basically schooled me on valuable information a homeowner should already know if they have a fire sprinkler system installed in their home. John ended up installing a new fire sprinkler pressure gage and a pressure release device at the back of the house. He had a lot of patience with me following him around and asking questions. With his permission, I recorded his instructions. It was for my reference and also to share with my family because of my forgetfulness. Thankful for the reasonable price charged, not to mention with superb service. I have to say that God sure used John Harden in our time of need. In a sense he rescued us by helping prevent what could have been a devastating nightmare. Again, thankful for his time and honesty. All in all, my husband and I are so thankful for John's service and professionalism. Impressive boss with integrity that can be trusted. Harden Fire Protection will be on my permanent list to call and refer others to when Fire Safety arises. read more

John was a God send answering on a Friday night when our garage was getting soaked from a broken fire sprinkler. Although we didn't have him come until first thing Saturday morning, it was a blessing to even find him because it was difficult locating a certified professional to work on residential sprinklers. He educated us on the issue and fixed it in a very timely manner, as well as made a recommendation for a pressure valve that should eliminate us from having this problem again. I would 1000% recommend him to anyone in need of his services. read more

My husband was installing a ceiling fan in the attic in our home and accidentally cracked the fire sprinkler pipe, flooded the upstairs bedrooms, and leaked into the garage. John immediately responded and gave a great fast estimate via text and explained in a phone call. He came today to do the repair, system flush, and inspection. He was on time, very friendly, professional, knowledgeable, and patient with me in answering all my questions and informing me how the system worked and what to look for in the future that would show signs of needing attention. Definitely can't say enough good things about this guy and his work. Bonus, less cost than any other estimate ( and I called 5 companies) I don't always go with the lowest estimate because the work is usually reflected in the price. Not in this case, I feel like I got the best of both worlds. Will use him again if needed and recommend him to all my friends and neighbors. read more
