The complete guide to why deck corners open with the seasons, why it matters, and how to close them for good — on new and existing decks.

Both the TopCap and FasciaCap lines are now protected by U.S. Design Patents — securing the innovation behind GAPCAP™'s decking solution.

GAPCAP™ has signed an agreement with Carter Lumber's corporate office, opening the door for any Carter Lumber location nationwide to carry GAPCAP™ products.

From a garage prototype to a patented product: how a 16-year deck builder's frustration with corner gaps became GAPCAP™.
