Building Maintenance

When stone masonry has shifted, bulged, or deteriorated past the point of patching, it has to come apart and go back together correctly. TNT dismantles failing stonework and rebuilds it to its original line, plumb, and profile, using salvaged and color-matched units set in mortar compatible with the wall.

When brick faces spall, crack, or break away, replacing the failed units restores both the strength and the watertight envelope of the wall.

Crack injection seals active leaks and structurally re-bonds cracked concrete and masonry from the inside, without large-scale demolition.

A breathable penetrating water repellent reduces water absorption into masonry while still letting trapped moisture escape, protection without sealing water in.

Spalled and deteriorated concrete on walls, columns, and overhead surfaces is repaired with structural materials that bond, last, and protect the rebar.

Tuckpointing renews the mortar joints that hold your masonry together and keep water out, restoring both strength and weather resistance before deterioration spreads.

Through-wall flashing intercepts water that gets into the wall and sends it back out, stopping infiltration at its source rather than chasing leaks.

Architectural terra cotta defines many historic facades. We repair and replace deteriorated units while preserving the building's original detail.

From chipped edges to spalled faces, we repair and replace architectural stone with color-matched materials and craftsmanship that blends in.

Stone consolidation strengthens crumbling, friable stone in place, preserving irreplaceable original material rather than replacing it.

Define the right scope and budget before work begins. We help owners and managers plan masonry projects so there are no costly surprises mid-project.

Traffic coating systems waterproof the surfaces people and vehicles travel on, protecting the structure beneath parking decks, plazas, and walkways.

Parapets are exposed to weather on multiple sides and deteriorate first. Rebuilding restores the roofline and stops water from entering the wall below.

Removing old paint from masonry restores the wall's ability to breathe and reveals the original brick or stone, done gently to protect the substrate.

Masonry staining permanently corrects mismatched or unattractive brick and stone color, chemically bonding to the masonry while keeping it breathable.

A masonry investigation gets trained hands and eyes directly on your building to find what's failing, prove why, and define exactly what it will take to fix it.

Lintels carry the masonry above your windows and doors. When they corrode or sag, the openings crack, and the fix protects the wall above.

When a facade begins to bow, separate, or shift, stabilization re-anchors and secures the masonry before it becomes a structural failure.

A breathable elastomeric coating protects and unifies an aging facade, bridging hairline cracks and shedding water while letting the wall breathe.

Sealant joints are sacrificial; they age and fail. Replacing them keeps water and air out at the building's most vulnerable transitions.

Decades of dirt, carbon, and biological growth dull a facade. Careful cleaning restores its appearance without harming the masonry beneath.
