We are the decking experts offering the most experienced staff and the largest inventory in the St. Louis Metro area, with the largest variety of decking products in Missouri.

Here at Hackmann's, we stock five major brands of composite decking with a large inventory of capped composite decking in each brand: Timbertech, Trex, Fiberon, Evergrain, and DecKorators. Capped composite decking is low maintenance, weather, rot and insect resistant, and will not warp or split; and with its protective PVC cap adds fade, stain, and scratch resistance.  We also offer railing to match each of these composite lines. 

In addition to capped composites, we also stock Azek brand  PVC decking and  Zuri Premium Decking by Royal.  We also offer on special order Endeck, Gorilla, and Lattitudes Decking from Missouri Vinyl Products, as well as Clubhouse, Fortress, Gossen, and Duralife Decking in a variety of colors.
