King and Son Septic installed a new septic system at a 100+ year-old home. They took care of all the details related to getting our septic up to code: inspection, permitting, installation. Is has been our pleasure to work with King and Son. They really know what to do and how to get it done!
We are very pleased with the job that King & Sons did, from scheduling our appointment and their flexibility to their communication about their arrival. Travis was very pleasant and did an efficient job while leaving everything clean. We would highly recommend King & Sons!

⭐️⭐️⭐️⭐️⭐️ 5-Star Service & Fair Pricing — Highly Recommend. We recently had our septic system’s back baffle replaced, and we couldn’t be more pleased with the experience. From start to finish, the team delivered professional, courteous, and efficient service. They arrived on time, clearly explained what needed to…
Excellent service. They work with you and explain everything well.
Please make sure you first understand their work guarantee. They said their work would solve my septic tank problem, but it didn't. They never figured out what the problem was, replaced something else, and the problem persists. Now they refuse to take responsibility and want to charge us thousands again, even though…
