At Sashco, we buck the notion that caulking failure is the norm. It’s not. We are obsessively focused on creating quality sealants. That’s why we don’t make good, better, best — only high-performance sealants for every project.

Lexel® is the tough elastic sealant for every interior and exterior job. It has superior adhesion to almost any surface, wet or dry, and is instantly waterproof! Lexel® is extremely elastic and has a 700% maximum joint movement so it won’t crack over time, meaning you only need to do a job once. It is paintable, sticks to itself and is crystal clear. In fact, it is 19 times clearer than silicone and won’t yellow or get cloudy over time

When there’s a nagging roof leak that others can’t fix, or when you don’t want to take your chances, use Through the Roof!® Its unique co-polymer rubber formula creates a permanent, invisible seal, even when applied in the middle of a rain storm. (It works great on dry surfaces, too). Through the Roof! will stick to almost any roofing surface – metal, plastic, asphalt, wood, concrete, and more. Plus, it won’t freeze.

Homes move. Window frames move away from the siding, or doors shift against the brick. This movement happens as the home settles as well as with temperature changes and even wind. If movement causes a sealant to crack, you can lose the air or moisture barrier in your home. That’s why you need Big Stretch®. With powerful adhesion and extreme elasticity, it will stick, twist, bend, compress, and stretch — 500% maximum stretch.

Why does mold grow so quickly? Because you’re feeding it! Mold feeds on body oils, shower products, cooking oils, and bacon grease that collect in the corners of your shower and kitchen. That’s why we created CleanSeal®, the first ever active enzyme caulk that breaks down these oils - eliminating mold food. By taking away the food, we literally strip mold of its power to grow.

It’s ugly. Your mortar cracks and your stucco streaks. Replacement and repeated repairs re-crack, not to mention that they’re costly and time-consuming. Forget the concrete powder, mix bucket, and big trowel. Just squeeze in Mor-Flexx® to repair crumbly mortar, cracked stucco, or textured walls. It’s easy, it’s fast, and it works. Mor-Flexx® is textured to blend in seamlessly with mortar and stucco.

Just Say No to Cracks! Step outside and you’re likely to see a concrete crack in less than two seconds flat. They’re in driveways, sidewalks, garages, patios, pool decks, and basements. Cracks harbor weeds and anthills, and cause toe injuries (ouch!). They’re eyesores that never seem to go away. Changes in temperature, moisture, shifting soils, and traffic only make them worse. Enough is enough! Use Slab®-The Serious Fix for Concrete Cracks. 

eXact Color® is the easiest and fastest way to create a custom color caulk. This 100% water-based acrylic sealant requires no special tools. Simply mix in any waterbased paint or stain to get an exact match. Forget about needing to have 50+ colors on hand. You only need this one to match your job.
