Martin Unlimited is a family business owned by Doug and Denise Martin. Started in their home in 1998, they have already outgrown a small commercial space. Now they have opened a bigger facility at 1125 East State Street in Cassopolis, Michigan, hired more employees, and expanded their product line.

Southwest Michigan’s authorized dealer and distributor for Royal Crown Limited, Doug and Denise sell Triple Crown vinyl fencing, Deck Lok systems, and Brock Vinyl Decks and docks. Royal Crown vinyl cuts like wood but lasts years longer and looks better without splitting, rotting or needing paint. Unlike treated wood, this durable product contains no toxic chemicals, is 100% recyclable, and available in three beautiful colors. Triple Crown residential and agricultural fencing comes in a variety of styles to enhance the appearance and value of any property. Strong and flexible, it is engineered to withstand rain, sun and snow. Brock Decks and Brock Docks have stylish, grooved surfaces, which are cool to the touch, slip-resistant and quick to drain water. Royal Crown’s newest deck system, Deck Lok, features wood grain look planks in complete deck, railing, and finishing packages. Royal Crown vinyl never needs sealing or painting and, best of all, the long-term investment is lower than treated and painted wooden docks, decks, and fencing.

Doug and Denise proudly supply this high-quality, maintenance-free vinyl. Martin Unlimited wholesales these top-of-the-line products to contractors and landscapers throughout the area. They always welcome new dealers to supply, as well. To complement Royal Crown’s fences and decks, Martin Unlimited also supplies a wide variety of gates, railings, arbors, and trellises.
