Why waterproof?
Star Tuckpointing exclusively utilizes silane/siloxane waterproofing agents that infiltrate deep into the masonry substrate and bond chemically to provide a superior barrier against the elements. Waterproofing agent is sprayed onto the surface and does not change the color or appearance of the masonry. There will be no shiny film or cloudy residue left on the brick. Our sealants generally last approximately 7-10 years. The warranty on this type of application is 3 years.
Technical guide
We use industrial-grade sealants engineered for Chicago's severe freeze-thaw cycles. Understand the technical differences, active solids, and manufacturer lifespans of the products available for your property.

Likely candidates
Single wythe cinder block and renaissance stone veneer walls are particularly porous and likely candidates for waterproofing.
Sandblasted and waterblasted brick is especially porous and benefits from a protective sealant.
Star Tuckpointing recommends sealing all types of cinder blocks to sustain the masonry work.

FAQ
Chicago's freeze-thaw cycle forces water into porous cinder block and mortar, then expands when it freezes, cracking and spalling the masonry. A silane-siloxane sealer lets moisture escape while blocking water absorption, dramatically extending the life of your walls.
A quality silane-siloxane sealer lasts 7 to 10 years on a Chicago exterior. Lifespan depends on wall exposure, sun, and drainage. Star Tuckpointing uses penetrating sealers that bond inside the masonry rather than forming a surface film that peels.
Tuckpointing first, then waterproofing. Sealing over deteriorated mortar traps moisture and accelerates damage. Star Tuckpointing repairs failed mortar joints and flashing, then applies sealer so the wall is structurally sound and water-resistant.
Not exactly. Sealers form a surface film, while penetrating waterproofers soak into the brick and bond internally. For Chicago exteriors, penetrating silane-siloxane waterproofers outperform surface sealers because they let vapor escape and resist UV breakdown.
