JN Corcoran Inc was founded in 2006 and is operated by a husband and wife team (John & Nikki). Since we started our business has steadily grown. In our business we have two areas, one is marine and the other is landscape/hardscape. We use the most advanced and the highest grade materials available. We constantly strive to introduce new and more innovative ideas into our business.

For the marine portion of our business we install dock and boathouse foundations, and breakwalls. We drive two types of pilings, steel and fiberglass. We also install CHANCE helical piers (ABChance.com) and are a certified CHANCE installer. We have the ability to drill through any rock or ledge surface. The lumber we use is a marine grade lumber. Our brackets are custom made and all of our brackets and hardware is coated with a hot dip galvanize. We apply for all agency permits.

For the landscape/hardscape portion of our business we install walkways, steps, patios, retaining walls, stone piers and fire pits. We also install Norway and Colorado Blue Spruce trees. We plant an array of shrubs and install premium hardwood mulch in brown or black. For our hardscape projects we use Techo-Bloc or Belgard pavers, fieldstone flagstone, bluestone and granite. We offer a spring clean up service.

Marine Grade Heavy Duty Lumber

The pressure treated lumber that we use is a marine grade heavy duty lumber. Our frames are constructed using 3” x 10” lumber which is available in custom length one piece boards, for example 30 footers.

Custom Made Piling Bracket

The brackets we use are custom made for each project. Steel brackets, welded and hot dipped galvanized.

All bolts are galvanized and recessed.

Skirting & Picture Frame Option

The decking that we use can be pressure treated wood or a composite material. There are a few options. Skirting is a nice finish to a dock or boathouse foundation and what we call picture frame. There are many advantages to using composite decking, low maintenance, slip and spill proof, splinter proof and also the option of using two tone colors

Two Tone Composite Decking Option.
