Dillon is THE only way to go! Best money spent! He is smart, skilled, and experienced. Takes very good care of you and goes above and beyond. Very personable. Great pricing, actually far better than 2 other guys who came out. I had massive backyard cleanup, bought a fixer upper house that was let go last 20yrs. Backyard was overgrown by blackberry, ivy, brush. 30hrs later, its clear!

We hired them to excavate and create a walkway thru our 2 acres of woods. They also cleared another area for a planned fruit orchard and cleared and created a pad for an above ground pool. They made quick work of it all too! They gave us exactly what we asked for at a reasonable rate. They even built a little cedar bench with some stumps and cedar plank. Then cut out a little seat from a tree they fell. Gotta love the little touches and considerations. Highly recommended!

Dillon was very responsive in helping us solve the drainage issue on my property. I was thankful for his quick turnaround time to schedule and execute the job. He even took the time to come out over the weekend to avoid additional flooding for an incoming storm early that week. I would recommend his services to family and friends.

I had a somewhat complicated project in Everett but In-Depth Excavation took care of it very professionally and on time. My project required tapping into main sewer from my property but under a big retaining wall. The guys got all the materials, Survayer, soil engineer and city and county inspectors handled. Everything went well and the project was done and approved by Silver Lake Sewer District and Sno County. All this was done within the quoted price. I would recommend In-Depth Excavation to anybody and I will definitely use them again in the future.

Our deck contractor hired Dillon to dig up our existing patio and replace it with a new larger patio that would incorporate the new deck. Dillon worked with us to make sure the new patio met our specifications. He was very responsive and managed to fit in time to bring a large layer of topsoil and rake out the area that had been dug up and chewed up during the excavation. We are very pleased with the final product.

Dillon and his crew completed an extensive job for us, that at least one other company wouldn’t touch. The knowledge he brought to our job site was incredible, and the team worked very efficiently. The outcome far exceeded our expectations. He was prompt with getting us a bid, payment was painless, and his professionalism was refreshing.



Meet the Owner,
Dillon Aschenbrenner

Dillon established In-Depth Excavation in 2018 following years of experience. What started as a side job for family and friends turned into an ambitious passion and career. Dillon served on the 24-hour on-call duty rotation team for five years. At his First-panel interview he was offered an entry-level position with Alderwood Water and Wastewater District (AWWD). Dillon advanced through the ranks, exceeded qualifications, and was the youngest to be promoted to Utility Worker Lead in company history.

In December 2017, Dillon was presented with the Arden Blackledge “Excellence in Leadership”  award which is the highest annual honor given at AWWD.

He was employed by various contractors working on storm, water, sewer mains, demo, plus grading and restoring for two years. Dillon proudly serves Western Washington and is on course for growth to establish In-Depth Excavation as a competitor in diverse markets. 

We treat our Clients, Team, and Other Contractors just like Family.
