About Us


Eric Swanson
President

Eric Swanson is a fourth generation carpenter builder.  His father was an AIA board certified architect who practiced in Florida for over 40 years.  The 2004 hurricane season, specifically on the US East Coast was the motivation for the invention and development of the Trap-Loc Building Products. 

25 years prior to founding Top Down Siding, LLC in 2007, Eric founded, co-owned and operated a custom manufacturing facility that serviced customers at the wholesale level. In addition, he created products that were sold in his own stores direct to retail.

Since that time the company has received several patents related to this building product technology with additional innovations and patents currently pending.
