Chicago Tuckpointing has over 25 years of experience water sealing and protecting all types of porous and above grade building surfaces. The sealant Chicago Tuckpointing applies is a transparent breathable layer that offers excellent protection against the freeze and thaw cycles, efflorescence, mold, wind driven rain and acid rain. Manufacturer specifications recommend re-applying a new layer of sealant every 10 years. Before applying a water sealant Chicago Tuckpointing will do a full assessment of the area that needs sealing. It’s important to replace any loose mortar and cracked bricks before applying a water sealant to any masonry surface. This is to insure that there is a solid base for the sealant to be applied.
