Waterproofing & Window Caulking

Masonry Waterproofing & Caulking Services in Chicagoland

Water is the single greatest threat to brick and stone structures. Greg Mason Inc offers commercial-grade masonry waterproofing and professional window caulking services to keep your building completely watertight. By sealing out moisture, we protect your property from freeze-thaw damage, interior mold growth, and costly structural deterioration.

The Importance of Breathable Masonry Sealants

Many amateur contractors make the mistake of painting bricks or applying film-forming sealers that trap moisture inside the wall. We only utilize premium silane and siloxane penetrating sealants. These advanced chemicals soak deep into the pores of the brick, repelling liquid rainwater while still allowing trapped water vapor to safely escape.
