Permit Acquisition

If the very word “permitting” makes you sweat, don’t worry. The permitting process can be overwhelming as it changes routinely. We’ve been doing it for decades. Let the experts ensure that your project is properly permitted.


There’s nothing like living on or around Flathead Lake in Western Montana, but the lake and lake conditions can place a lot of wear and tear on docks and buildings. We can renovate and restore your project to like-new condition.

Our Unique Area of Specialization

Dock Structures

Dock Structures

We can use any number of materials to create a structure that fits the size and specifications of the landscape. We have built timber dock structures that draw on the natural Montana landscape, as well as steel buildings that stand the test of time.



We bring years of custom building experience and quality construction to each and every project, regardless of size and scope. Remember, we build year-round, and in low water.
Pile Driving

Pile Driving

Building on a sound foundation is key to the longevity of any dock. Our experienced crew is well-versed with the Flathead lake-bed, as well as the best way to insert piling into the ground to ensure a solid, quality dock that will last for years to come.
