Sound familiar?

Your waterfront is losing value every season you wait.

Silt builds up. Seawalls lean. Shorelines wash away. Each year it gets harder — and more expensive — to fix.

  • ✕ Your boat can't reach the dock anymore
  • ✕ The lake is shallow, weedy or smells bad
  • ✕ Your seawall is leaning, rusting or leaking soil
  • ✕ Your yard or bluff is washing into the water
  • ✕ You don't know which permits you need — or where to start

Frequently Asked Questions

Do you handle the permits?

Yes. We prepare the drawings, surveys and the Michigan Joint Permit Application (EGLE + U.S. Army Corps of Engineers), plus local soil-erosion and zoning permits.

How long do permits take in Michigan?

Most waterfront permits in Michigan are issued in about 2 to 6 months. Starting early is the best way to hit your construction window.

How much does lake dredging cost?

It depends mostly on cubic yards removed, distance to the spoils site, access and mobilization. Use our free calculator to get your volume, then request a free estimate.

Which seawall material is best for Michigan?

Steel sheet piling is the most common choice: strong, long-lasting in heavier gauges, and good in ice. Vinyl, aluminum and wood each fit specific situations.

What areas do you serve?

We're based in Fruitport and serve West Michigan, including Muskegon, Grand Haven, Spring Lake, Holland, Whitehall and Grand Rapids-area lakes, plus larger projects across the Great Lakes region.

Do you work with lake associations and townships?

Yes. We work with lake boards, associations, townships and engineers on lake dredging and dam projects — including projects funded by special assessment districts or grants.
