Great service!
If I could give 10 stars, I absolutely would! King & Sons came out today to pump my septic tank and snake my sewer line, and I couldn’t be more impressed with their service. Randy, his grandfather, and another team member (I hate I can’t remember his name!) were absolutely outstanding. From the moment they…

King &Sons is amazing. After being told by another company they would need to rip up our front yard and replace the septic lines and a few other things, we reached out to Randy King and he was here in an hour and had our system working again in another hour. Told us our system was fine and just needed cleaning. If I…

We've been customers of King & Sons for over 30 years. They have always been friendly, honest, professional, and reliable that entire time. Today, we had an emergency.

Had King & Sons drain my septic tank for the first time in over 15 years. Brian dug up the lid and got the job done. Price was very reasonable and scheduled service was done on time. Highly recommend this company.

I have used this services for more than 30 years , alway on time and excellent Service
We just moved into our home last June and weren’t entirely sure when our septic was last pumped or where it even was located. I asked around if anyone knew a good septic company that they would recommend, and king and sons was spoken highly of. I called and left a message requesting service and got a quick response…
Good service. Recommend
We had King and Sons pump our septic. They pumped the system and then shared how we could keep it kept up better and also made recommendations for state of system. They will be making improvements - new lid in just 2 days. Great turnaround. Nice family business!
Very professional, on time, and informative. Was a bit more expensive this year then the company I used a couple years ago but after calling around, all the companies have raised their prices. I'd use them next time for sure.
Excellent
We had our septic system cleaned out for the first time. King & Sons were very professional and curious. We will be using you all again when the time comes.
They are all so friendly and got my issue resolved quickly.
