Finding a Vendor that you can consider a true Partner is rare, but DuxxBak Composite Decking is that Vendor!  Our relationship with DuxxBak is nothing if not special.  Jerry and his team are friendly, professional and the most helpful people that I deal with.  Their products are high quality, competitively priced and they always ship on time!  During this time of inventory outages and long lead times, DuxxBak has always had product ready to ship and this has increased our market share from our competitors.

Their innovative line of products sells themselves and DuxxBak has remedied the issues with composite decking on many fronts! I hold DuxxBak in high esteem as a vendor, but the most important thing is our relationship as friends.

Just wanted to put in a word on the benefits of the Duxxbak decking. It’s unique design gives us the capability to offer our customers a dry space under their deck and is much more cost-effective than purchasing and installing a separate under deck system. Additionally,  it is easy to install, colorfast, attractive and gives a solid floor with no visible fasteners. Couple that with one of the best warranties in the business and you have a product that practically sells itself.
