OUR HISTORY
Experts in sealants and waterproofing since 1974.
JLA Supply, Inc., doing business as Sealant Specialists, was started in 1974 in Portland, OR when John Latta began distributing foam tape and insulating glass products to the window manufacturing and glazing industry. As demand increased, a second office was opened in Seattle, WA in 1978. The early 1980’s saw the start of the foam tape conversion process along with continued distribution. JLA Supply is now the largest converter of foam tape on the west coast.
Expansion into the sealant and waterproofing markets came in the mid 1980’s. The Boise, ID office was added in the 1990’s along with additional products from national manufacturers of water repellents, fire stopping and deck coatings.
In 2004 Seco Construction Supply was purchased with locations in Yakima, WA and Spokane, WA. Seco had a strong penetration into the concrete accessories market and brought with it a rental business supporting the concrete forming and tilt-up industries. In 2022, Cascade Concrete Accessories was purchased, increasing our Division 3 presence in the Oregon market.
JLA Supply, Inc., under its three DBAs, continues to serve the northwest construction market furnishing nationally known products with primary emphasis on CSI Divisions 3, 7, 9.
