What we actually build.

We do four things on the waterfront, and we’re honest about all of them. Each entry below is a project we’ll quote, permit, and stand behind for decades.

Permits, materials, dockmaster electrical & water hookup, full cleanup.

SPC · 02 Concrete seawall holding back ocean waves

Seawalls & Bulkheads

Murus aquaticus · vinyl, concrete, wood

Read the entry →
Field note

If your wall is leaning, weeping, or pushed back > 1″ from level, it’s repairable — don’t wait for a collapse to rebuild from scratch.

SPC · 03 Luxury boats moored at a private marina

Boat Lifts

Elevator nauticus · 4,500 – 24,000 lb

Best for
Anyone tired of hull growth, stained gel coat, or worrying about storms with the boat in the water.

Includes
Lift, install, remote, GFCI panel, 2-yr install warranty + manufacturer warranty.
Read the entry →
Field note

Add a lift to a new dock build and you save ~$1,800 vs. retrofitting later — pilings get sized for it the first time.

The work either holds for the next hurricane, or it doesn’t. There’s no grey area on the water-line — so we don’t leave any in the build. — Bill Theil, owner
