Now signing authorized dealers
Stock the only deck system that keeps the space underneath dry.
AmeriDex is the patented above-joist Dryspace system. Cellular PVC boards lock onto the Dexerdry seal at install, so 100% of rain runs off the deck instead of into the joists. Give your customers something your competitors simply cannot sell.
Built for the trades that build near the water

A product your competitors can't put on the shelf next to yours.
Decking is a commodity. Same boards, same margins, a race to the bottom on price. AmeriDex is a patented, differentiated system that lets you sell on value instead of competing on price.
Higher margins, no price war
A patented system with no direct shelf equivalent means you set the value conversation, not the lowest bidder down the street.
Protected dealer territory
We sign a limited number of dealers per market. Lock in your area before a competitor does and own the AmeriDex name locally.
Marketing that drives demand
Sales sheets, samples, social creative, and homeowner-facing ads. We help generate the leads that send buyers to you.
Made in the USA, in stock
Manufactured by Patwin Plastics since 1971. Domestic production means reliable supply and lead times you can quote with confidence.
A 25-year warranty to sell behind
Confidence at the counter. A long, written warranty closes hesitant buyers and reduces callbacks for your installers.
Repeat, attach-rate revenue
Every linear foot of deck pulls through seal, fasteners, and accessories. Recurring system sales, not one-and-done boards.
The demand is already there
Your customers are paying for square footage they can't use.
On every raised deck and waterfront dock, rain passes straight through the gaps, soaking joists and wasting the space below. Homeowners don't see the rot until year twelve, and by then it's a full tear-out.
AmeriDex stops water at the walking surface on day one and turns the area underneath into dry, usable space: covered storage, an outdoor kitchen, a year-round lounge. That's a story that sells itself, and you're the only dealer in town who can tell it.

Dealer questions, answered.
What builders, lumber yards, and marine suppliers ask before signing on.
Is my territory protected?
Yes. We sign a limited number of authorized dealers per market so you are not competing with the dealer down the street on the same product. Apply early to lock in your area before someone else does. We will confirm exact territory details when we talk.
Is there a minimum order to become a dealer?
We keep the entry simple and reasonable so you can stock the system and prove it out without an oversized commitment. We will walk you through opening order and restock terms based on your market size when you apply.
What lead times can I quote my customers?
AmeriDex is manufactured in the USA by Patwin Plastics, so supply is domestic and predictable. We give every dealer current lead times up front so you can quote install dates with confidence.
What does AmeriDex do to help me sell?
You get real board and seal samples, sales sheets, counter and showroom displays, social creative, and homeowner-facing advertising that drives demand into your market. We treat your sell-through as our job too.
Who installs it, and is training available?
AmeriDex installs on a conventional 16-inch on-center frame, no special substructure. We provide installation guidance and instructional videos so your builders are confident on their first job.
What's the warranty I'm selling behind?
A 25-year residential limited warranty and a 10-year limited commercial warranty on the deck board system. A long written warranty closes hesitant buyers at your counter.
