Sashco

Since 1936, Sashco has been a leader in high-performance sealants, caulks and finishing products innovation for conventional home construction and log/wood homes.

At Sashco, we’re driven by a passion to make products that work right the first time. Like you, we get frustrated by the toy that breaks, screwdrivers that bend and tires that wear out too soon.

That’s why you won’t find good-better-best product lines
at Sashco. We only make high-performance products
designed to work best for their applications. We like
to call it “delighting the customer with a better way.”

   While supply chains are disrupted, many contractors are
   having difficulty finding their go-to products, which can
   be unsettling when the integrity of a job depends on it.

   We produced this special edition of Les's Corner, which
   reviews the various sealant technologies that can be
   substituted for each other, examples of each, and
   the differences you can expect when doing so.

Through the Roof!® – It Seals Leaks That Asphalt Can’t!

Use it on flashing, vent pipes, skylights, gutters/downspouts, ductwork/vents, chimneys, shingles/shakes, flat roof tile, and metal RV roofs.
Available in cartridges or brush-on grade.
