I recently had Desormo Excavation to replace my old leach field, and I cannot recommend them enough. The owner and operator, Tim Desormo, was incredibly prompt, fair in his pricing, and highly efficient. Tim and his assistant, Alec, took on the task of replacing my outdated non-functioning system with a brand-new, larger capacity leach field. Both Tim and Alec were exceptionally knowledgeable, hardworking, and adept at handling the excavation and technical aspects of the job. They made a complicated project look easy and completed everything in less than a day.

Desormo Excavation was amazing. They put in two stone pads for us today. They scheduled us so quickly, and they did a great job. They are professional but personable as well. They go right to work and get the job done for a fair price. It's nice to know there are companies you can still trust and count on. I highly recommend Desormo Excavation if you need any work done. Thank you Tim and AJ, you did a great job! Know that you are appreciated for what you do.

From the Google listing, checked 30 Aug 2026.

Several reviews describe drain field and leach field replacement jobs finished fast. Robert wrote that the crew "completed everything in less than a day" on a new leach field, and Diane said the crew arrived early and worked quickly. Reviewers name Tim Desormo, Alec and AJ as the people on the job, and more than one mentions the yard seeded and cleaned up afterward.

Before You Call

If a tank starts acting up as it refills, the question worth asking on the phone is whether a plugged outlet baffle could be the cause. Baffle replacement is work Desormo Excavation does, and Tim can tell you if that matches what you are seeing.
