A. J. Buerkle Plumbing Company is an excellent company to use if you are having plumbing problems. They are professional, courteous and efficient. I had a toilet leaking in my bathroom which damaged the sub-floor, tile floor and ceiling below. Mr. Buerkle came out and diagnosed the problem and had all the specialists needed to fix the problem. He had a carpenter available, a tile person and a plasterer for me to use. He took all of the stress off of me to get the problem solved. I would highly recommend using A.J. Buerkle.

I wanted to post a whole-hearted and enthusiastic recommendation for AJ Buerkle Plumbing Heating and Air Conditioning. We had an obscure leak from our 2nd floor laundry room into our kitchen. It was not easy to locate what was causing the leak. It involved cutting holes in a wall and a ceiling to locate the problem area and a remote camera to understand the problem. AJ Buerkle (father & son) managed the entire problem from beginning to end including a second professional to utilize a remote camera and then scheduling dry wall repair.

Throughout the entire process they were courteous, informative, and extremely neat while doing their work. I was so grateful that they didn't simply identify a problem and leave me to figure out how to proceed to fix it. I cannot give a high enough recommendation for this company. The care, thoroughness and professionalism they displayed was what you hope for when facing a problem in your home but is not always easy to find. They removed all the stress for me while dealing with an urgent problem. It is a local family business that I am happy to support and recommend.
