Masonry & Concrete Restoration Services
Stone Rebuilding
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.
Brick Repair & Replacement
When brick faces spall, crack, or break away, TNT cuts out the failed units and replaces them with brick matched in size, color, and texture, restoring the strength and watertight envelope of commercial and historic walls.
Crack / Epoxy Injection
Crack injection seals active leaks and structurally re-bonds cracked concrete and masonry from the inside, without large-scale demolition.
Masonry Waterproofing & Water Repellents
Waterproofing a commercial masonry building starts with the repairs (tuckpointing, through-wall flashing, and sealants), then a breathable penetrating water repellent that cuts water absorption while letting trapped moisture escape.

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

Tuckpointing
TNT is a commercial tuckpointing contractor serving Iowa, the Quad Cities, and western Illinois. We renew the mortar joints that hold your masonry together and keep water out, with mortar matched to your building so the repair lasts.

Through-Wall Flashing
Through-wall flashing catches the water that gets into a masonry wall and sends it back out. TNT installs and replaces flashing at lintels, shelf angles, parapets, and window heads, so leaks stop at the source instead of being chased from the inside.

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

Limestone & Stone Repair
From chipped edges to spalled faces, TNT restores limestone and architectural stone on commercial and historic buildings, patching with color-matched mortars and replacing units past saving. Stone that has moved out of plane needs stone rebuilding.

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

Project Scope & Budgeting Assistance
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.

Parking Garage Repair & Coatings
Traffic coating systems waterproof the surfaces people and vehicles travel on. TNT applies pedestrian and vehicular coatings to parking garages, ramps, plazas, and walkways to protect the concrete structure below.

Parapet Repair & Rebuilding
Parapets take weather on both faces and across the top, so they are usually the first masonry on a building to fail. TNT repairs and rebuilds parapet walls, integrating new coping and through-wall flashing to keep water out of the wall below.

Paint Stripping
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 & Facade Investigations
A facade inspection and masonry investigation puts 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, before you set a budget.

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

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

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

FAQs
Does TNT provide masonry condition assessments?
Yes. We offer masonry investigations and project scoping services that evaluate the condition of a building's masonry, identify areas of concern, and help owners prioritize and budget for necessary work.
What happens if masonry damage is ignored?
Untreated masonry damage worsens with every freeze-thaw cycle, allowing moisture deeper into the wall system. What starts as minor mortar joint failure can progress to structural instability, interior water damage, and repair costs that far exceed what early intervention would have required.
Can masonry restoration be done in cold weather?
Our primary season runs from mid-February through the end of November. However, interior masonry work and exterior work using heated enclosures can be performed outside that window when conditions require it.
How long does a typical restoration project take?
Timelines vary based on scope and complexity — targeted repairs may take one to two weeks, while large-scale facade restorations can span several months. Our estimators assess the project on-site and provide a detailed proposal with anticipated duration, and we work with building owners to phase work when needed to accommodate budgets and operations.
Does TNT work on both structural and cosmetic masonry issues?
Yes. We self-perform all masonry restoration work, from structural repairs like lintel replacement, parapet rebuilding, and facade stabilization to cosmetic work like mortar matching and stone patching. We address the full spectrum of masonry conditions.
What is the difference between tuckpointing and repointing?
Repointing is the removal of deteriorated mortar and its replacement with new mortar. Tuckpointing is a specific technique that uses two contrasting colors of mortar to create the appearance of fine, uniform joints. In common usage, the terms are often used interchangeably to describe mortar joint repair.
How do you match historic mortar and brick?
Our team includes lime-putty-certified craftsmen who analyze original mortar composition, color, aggregate, and joint profile to produce an accurate match. Brick and stone matching follows a similar process of sourcing materials that align with the original in color, texture, and dimension.
What are the signs a building needs masonry restoration?
Visible warning signs include crumbling or recessed mortar joints, cracked or spalling bricks, efflorescence (white salt deposits), bowing walls, and water staining on interior surfaces. If any of these are present, a professional assessment should be scheduled promptly.
How often does commercial masonry need maintenance?
Most commercial masonry should be inspected every three to five years, with mortar joints and sealants checked on an ongoing basis. Catching deterioration early prevents small problems from becoming major structural issues.
What causes masonry deterioration on commercial buildings?
The primary cause is moisture entering the wall system and then cycling through freeze-thaw expansion, which cracks mortar and spalls brick and stone over time. Wind-driven rain, failed caulking, poor flashing, deferred maintenance, and the use of incompatible repair materials all accelerate the process.
What is the difference between masonry restoration and masonry repair?
Masonry restoration returns a building's masonry to its original condition and appearance, addressing widespread deterioration across a facade. Masonry repair targets specific localized damage such as cracked mortar joints, broken bricks, or a failing lintel.
