Client Feedback

What Our Clients Say

We let our work speak for itself — but don't just take our word for it.

Trinity Excavating handled the entire site prep for our new home build. They were professional, on schedule, and the grading was perfect. Our builder said it was the easiest site he's worked on. Highly recommend.

Homeowner New Home Build · Olathe

We needed a large commercial lot graded and drained before our construction crew could start. Trinity showed up with the right equipment and a crew that worked efficiently. Completed ahead of schedule and within budget.

General Contractor Commercial Site · Johnson County

Had a challenging drainage issue at our property that two other companies said was impossible. Trinity diagnosed the problem quickly and installed a solution that actually works. Fair price and excellent communication throughout.
