Freeze-Thaw Spalling
Protecting Chicago Brick from Freeze-Thaw Damage.
Brick is a naturally porous material. In Chicago, when wind-driven rain saturates the masonry, the moisture becomes trapped. During the winter, this trapped water freezes and expands, causing the faces of the bricks to pop off — a process known as spalling. Furthermore, applying a surface sealant over deteriorating mortar will not stop leaks.
At Star Tuckpointing, we focus on structural integrity first. We ensure all mortar joints are solid, performing necessary tuckpointing prep work before applying our deep-penetrating silane/siloxane brick sealers. This creates an invisible, breathable barrier that repels water without trapping internal moisture or altering the natural color of your building.
Our Standards
Our Brick Waterproofing Standards
Silane/Siloxane Technology
We exclusively use professional-grade penetrating water repellents that chemically bond with the brick substrate, rather than cheap film-forming acrylics that peel and trap moisture.
Breathable Protection
Our application allows water vapor to escape from the interior of the building while blocking exterior rain, preventing interior mold and structural rot.
No Discoloration
The sealant dries completely clear, leaving no shiny or cloudy residue on your historic Chicago brick.
Visual Proof
The Star Tuckpointing Standard.

FAQ
Brick Wall Waterproofing in Chicago - Frequently Asked Questions
Does my brick wall need waterproofing?
If your Chicago brick wall shows efflorescence, spalling bricks, or damp interior walls, waterproofing helps. Even healthy walls benefit from a penetrating sealer that blocks water absorption while letting the masonry breathe.
How much does it cost to waterproof a brick wall in Chicago?
Waterproofing a brick wall in Chicago typically costs $2 to $5 per square foot depending on wall height, access, and condition. Star Tuckpointing provides a free written estimate that separates sealing from any needed tuckpointing or flashing repairs.
How long does brick waterproofing last in Chicago?
A penetrating silane-siloxane sealer lasts 7 to 10 years on a Chicago exterior. South- and west-facing walls in full sun may need reapplication sooner. Star Tuckpointing uses commercial-grade sealers engineered for Midwest freeze-thaw conditions.
Should I seal my brick?
Sealing can protect the wall through the freeze-thaw season. The ideal window is April through November when temperatures stay above 40 degrees. Star Tuckpointing schedules sealing around the weather.
