  • BIG-BigStretch-Garage

    Homes move. Window frames pull away from the siding or doors shift against the brick. They move when the temperature changes, the rain falls, the wind blows or the earth quakes. Most caulks can’t take it – they dry hard and crack. That’s why you need Big Stretch® high performance water-based sealant.  Its powerful adhesion and extreme elasticity will stick, twist, bend, compress, and stretch – more than 500% of original size! – to handle most any movement your home can dish out, all without cracking.

    • soffits
    • eaves
