If you're looking for a big, flashy company to handle your septic work and excavation in Prescott, Dewey-Humboldt, Mayer, Prescott Valley, and Chino Valley, AZ, it might be prudent to keep on looking for another company-after all, we are essentially a one-man operation!
When our leach field began to fail we called a company with 32 years experience. Communication was difficult from the beginning and after the perc test became nearly impossible. We decided to try Kelmac. Communication was always quick and clear. Kelly showed up when he said he would and and never left us wondering what the project status was.

We are building a new home and have had a number of hurdles but the septic system was not one of them. I contacted Kelmac and they took care of everything. The system was installed without issue. In fact I changed the location of the leach lines after starting the permit process and Kelmac knew what would need to be done for the new design to pass inspection. This has probably been the easiest and trouble free aspect of our build so far.

I needed a second opinion on my septic system issue. The septic tank company I use highly recommended Kelly. I am so happy I called him! He was on time, professional, and most importantly...honest. He took the time to explain how everything worked and answered all of my questions. I will ONLY call Kelly the next time I have a septic problem.

So I call this guy (Kelly) to get a second opinion on an estimate I had just received to repair my septic system. I emailed him all the info and docs that I had received from the company. (Real Estate deal, not my choice) He reviews them, we talk and he winds up making a recommendation that doesn't even include him making a dime. Wow. If that's not a good litmus test for someone that's trustworthy what is? At no time did he bash the other company and he spoke with a lot of knowledge and common sense.
This was such a tremendous help because it allowed me to regroup and focus on the task at hand

I called Kelly because we were facing a potential problem with our current septic system related to a home remodel project. I was told by another septic technician that Kelly is the only guy he trusts to dig and install septic systems. That kind of insider information you don't ignore! Kelly was very friendly and helpful over the phone; and as it took several days for me to find out all of the information on how we needed to proceed with our project, Kelly called multiple times to follow up and check on how we were doing. In the end, we did not need to make changes to our septic system, but I was

Do you know how sometimes people write that if they could give six stars they would?! That is how I feel about KelMac! Kelly has provided (and continues to provide) outstanding and professional service. His insight and suggestions have been invaluable as we develop our raw land. I've also found him to be honest and ethical. We do not hesitate to recommend KelMac.

I recently had to install an alternative leach field on my property. I called two local septic tank companies and asked who they might recommend. They both spoke very highly of Kel-Mac Excavation. Kelly did a great job on the project. He always showed up when he said he would and consulted with me on every step of the job. I'm highly satisfied with Kelly and the job he did and would recommend him to anyone.

Kelly did an awesome job with my alternative septic installation. He was very professional and responsive throughout the entire project. He even sent me pictures of progress when I wasn't able to be there. Very reliable and honest. I would not hesitate in recommending him or using him for a future project.

KelMac did an excellent job of repairing my driveway after it was destroyed during the June 16, 2017 monsoon storm and subsequent ones. He did a thorough assessment, corrected run-off issues, and put new gravel on the road. Kelly is punctual, skilled, and ethical. He did the work exactly as he said he would do it. I agree with one of the other reviewers: Kelly's also a nice guy and easy to work with.
