Frequently Asked Questions – Dock Installation on harsens island
Yes. Most dock installations on Lake St. Clair require approval from the Michigan Department of Environment, Great Lakes, and Energy (EGLE). In some cases, the City of St. Clair Shores may also have local requirements. We handle all necessary permitting for you.
That depends on your shoreline, water depth, and how you plan to use the dock. Permanent docks are great for long-term, year-round use. Seasonal docks can be removed before winter. Floating docks work well in deeper or fluctuating water. We’ll assess your site and recommend the ideal option.
Most installations take between 2 to 5 days after permits are approved. Weather, materials, and shoreline access can affect the timeline. We provide clear scheduling and communication from start to finish.
We use marine-grade materials including pressure-treated lumber, composite decking, galvanized fasteners, and aluminum frames—each selected for durability against water, sun, and freeze-thaw cycles.
Permanent docks are designed to handle winter conditions, but seasonal docks should be removed to avoid ice damage. We offer seasonal removal and reinstallation services to protect your investment.
