Quality Marine Construction — Dock Building & Marine Contractor in Gananoque, 1000 Islands

Quality Marine Construction is a Gananoque-based marine contracting company operated by Jon Mills, a lifetime Gananoque resident who has spent his career working on the waterways and shorelines of the Thousand Islands. Jon is both a pipefitter and a certified welder, which means Quality Marine handles structural marine work — dock frames, boathouse repairs, steel fabrication — in-house rather than subcontracting specialty tasks to outside trades. The shop is located at 695 Stone Street in Gananoque, and the team operates with the kind of local knowledge and island-access logistics that waterfront property owners genuinely need: they know the channels, the tides, the access points, and the engineering quirks of shoreline construction in this particular stretch of the St. Lawrence.

Services

  • Dock Construction & Replacement — New dock installations, full rebuilds, and structural assessments for aging shoreline infrastructure across the Thousand Islands waterway
  • Boathouse Repairs & Upgrades — Frame repair, decking replacement, lift system support, and weatherproofing for boathouses of all sizes and configurations
  • Barge Service to the Islands — Material transport and on-site construction work at island properties with limited mainland-direct access — a capability that most area contractors simply don’t have
  • Custom On-Site Welding — Structural steel fabrication, custom hardware manufacturing, and weld repair for marine and waterfront applications
  • Anchor Resetting & Mooring Hardware — Anchor chain inspection and resetting, mooring hardware replacement, and shoreline anchoring systems for seasonal and year-round watercraft

Service Area

Quality Marine Construction serves Gananoque and the broader Thousand Islands waterway, including island properties, riverfront estates, and lakefront cottages across the Leeds County and Frontenac County shoreline corridor.

Why It’s on home.renovation.reviews

Waterfront property owners in the 1000 Islands face a category of infrastructure work — docks, boathouses, marine access — that most general contractors simply don’t handle. Quality Marine fills that gap with welding certifications, island logistics, and the owner’s lifetime of local knowledge baked in. It belongs in a directory that takes eastern Ontario’s distinctive property landscape seriously.
