Tuck point & Masonry Repair



Many older chimneys and fireplaces were built using a softer grade of mortar which was prevalent for the period. Over the years these soft mortar joints tend to soften and crumble away as they are exposed to environmental acids and moisture. Expansion and contraction of brick and natural harmonic vibrations also cause these older mortar joints to erode and fall apart. If older chimneys are not tuck pointed or have the mortar joints ground out and refilled with a new higher grade of mortar they can begin to lean and pose a major public safety hazard.

Without the use of specialty tuck point grinders with attached dust control systems, tuck pointing can be an extremely dirty and dangerously dusty repair. We grind out the old mortar joints (with a dustless tuck point grinder)to a depth of ½ inch to ¾ inch depending on brick or block construction,  clean the mortar joints with three stage filtered vacuum, moisten, and repack the joints with a blended mortar of sand, portland cement, lime, and latex acrylic additive for superior bond strength and water resistance. Acid wash and mortar color matching is also available. 
Tuck pointing can be an extremely dusty and dirty repair. Insist contractors use dust control equipment and carry full liability insurance.
