Built by two partners who believe in doing it right.
Founded by Danny and Isaac, partners who have worked together in the construction industry for years, GreyLine Construction has grown by earning our clients' trust one project at a time.
Two partners, one standard of work
GreyLine Construction was founded with a simple goal: provide dependable construction services built on integrity, quality craftsmanship, and honest communication. After years of hands-on experience in the construction industry, we recognized a need for a contractor that prioritizes doing the job right over simply getting it done quickly.
From residential repairs to commercial construction and structural projects, our company was built on the belief that every customer deserves reliable service, clear communication, and lasting results. Today, we continue to grow by earning our clients' trust one project at a time.
Danny and Isaac have worked together in this industry for years, and that partnership, built on shared standards and mutual trust, is the foundation GreyLine Construction runs on today.
Most of the construction work on our projects is done by our own employees. When a project needs specialty trades such as electrical, plumbing, or HVAC, we subcontract that work as needed.
- ✓Quality craftsmanship over shortcuts
- ✓Our own crews do most of the work
- ✓Honest, transparent communication
- ✓Licensed, insured & bonded

Rooted in Twin Falls, built for all of Idaho
GreyLine Construction is based in Twin Falls, Idaho, right in the heart of the Magic Valley, and that's still where the bulk of our day-to-day work happens, from Buhl and Jerome to Gooding and Wendell.
As our reputation has grown, so has our reach. We now take on residential and commercial projects statewide, from the Treasure Valley to Eastern Idaho and the Panhandle, with the same standard of communication and craftsmanship no matter how far the job is from home.
