Dock Construction

A dock is a building in the worst environment on your property. Ours are engineered for ice, wake and wind - and built from the water, properly.

Docks we build

  • Fixed piers on driven or augured pilings
  • Floating docks that ride the water level
  • Pipe docks for seasonal removal
  • Swim platforms, sun decks and boat slips
  • Composite or treated decking - honest pros and cons of each
  • Full permitting through shoreline authorities

Built for your water, not water in general

Depth, bottom composition, ice behavior, prevailing wind and wake exposure - every shoreline is its own engineering problem. We assess yours from the water, spec pilings and framing for the real conditions, and use marine-grade hardware because regular galvanized quietly dissolves out here.

Permits are their own weather system; we've run the shoreline-permit gauntlet for years and handle the applications, drawings and inspector conversations as part of the job.

Common questions

How long does a dock take?

Permitting is the long pole - weeks to months by jurisdiction. Construction itself typically runs days to a couple of weeks once approved. Start the conversation a season early if you can.

Composite or wood decking?

Composite costs more up front, then does nothing but get hosed off for twenty years. Good treated lumber is honest value with periodic care. We build both and will price both.

What about ice?

Design question one around here. Fixed docks get ice-rated pilings or seasonal sections; floaters get positioned or pulled. Your dock will have an ice plan.

Your shoreline is wasted without one.
