Tuck Pointing

Tuck-pointing: When mortar joints within the bricks start to deteriorate, crack or show voids, Tuck-pointing is preformed to reinforce the structure, seal the surface of the mortar and to keep rainwater out. Tuck-pointing consists of grinding out roughly 3/4" of damaged mortar. We specialize in mortar matching. During our Tuck-pointing process, we would use custom polymer modified mortar (

Vertical Cracks (Stitching)

The bricks are the actual strength in a chimney. The mortar within the bricks acts more like a glue to hold the bricks together. Mortar in itself varies in strength anywhere between 750psi to 2500 psi. The strength of average concrete bricks however, varies between 4,000psi to 6,000psi, and clay bricks vary from 8,000psi to 10,000 psi. When Vertical Cracking is found through bricks, it me

When the exterior moisture evaporates from the masonry, this leaves behind a chalky, unsightly white film. Efflorescence in itself is only a cosmetic i
