Serving Idaho Counties: Ada, Canyon, Payette and Boise
"Expect the best and get it!"

For more than three decades, Patrick Feely has been the driving force behind quality excavation and underground utility work across Ada, Canyon, Payette, and Boise Counties. As the owner of Shamrock Construction & Excavating, Patrick brings a rare combination of field experience, project management skill, and customer-first leadership to every job.
Patrick built his career on a simple philosophy: do the work right the first time, communicate clearly, and treat every project as if it were your own property. That mindset has made him a trusted name throughout Boise, Meridian, Eagle, Garden City, Star, Nampa, Caldwell, Kuna, Middleton, New Plymouth, Fruitland, and Payette.
His passion for the trades began early, and over the years, he expanded his expertise across excavation, drainage, utility repair, septic systems, demolition, and multi-phase site development. Today, Patrick is known for taking on the challenging projects—complex sites, tight deadlines, underground failures, and multi-discipline builds—while delivering the reliable results Idaho homeowners and builders count on.
Above all, Patrick believes that a contractor should bring peace of mind. That’s why he ensures every client gets direct communication, honest guidance, and a superintendent dedicated to overseeing each phase of the project. If a concern comes up, Patrick treats it as priority number one.
Shamrock Construction & Excavating was built to solve the kinds of problems that require skill, planning, and dependable execution. The company specialises in multi-phased and highly technical projects, saving clients time, stress, and unnecessary costs by handling everything from underground utilities to full site preparation.
With 24/7 emergency service, a fleet of modern equipment, and highly trained operators, Shamrock serves residential, commercial, and municipal clients across Southwest Idaho. Every project—big or small—receives the same professional attention and commitment to quality.

Shamrock’s strength lies in communication. Every client receives a dedicated superintendent, clear expectations, and updates throughout the entire project. Patrick’s team ensures you always know what’s happening, why it's happening, and what comes next.
