FAQs
Does TNT do residential work?
No. We do not perform work on homes or residential properties. We are an exclusively commercial masonry restoration contractor, and our crews, equipment, certifications, and processes are built for commercial, institutional, historic, and industrial buildings.
How do I know if my building needs masonry work?
Common signs include crumbling or recessed mortar joints, cracked or spalling bricks, water staining on interior walls, and efflorescence (white salt deposits on masonry surfaces). If your commercial building shows any of these symptoms, the damage is progressing. Submit a request through our website or call us for an on-site assessment.
What industries and building types does TNT serve?
We serve six primary markets: commercial and retail including healthcare, historic preservation, institutional buildings such as courthouses and government facilities, education, multifamily housing, and industrial. Roughly half of our work involves historic preservation, and institutional projects tend to be our largest by dollar value.
Is TNT licensed and insured?
Yes. We carry full commercial insurance and maintain all licensing required for the states and municipalities where we work. We have been in business since 1993, serving commercial building owners across four states.
Does TNT offer emergency masonry services?
Yes. We can mobilize for urgent commercial masonry situations where structural safety or water infiltration demands immediate attention. If your building has an emergency need, contact us directly and we will work to get crews to your site as quickly as possible.
What does a typical project timeline look like?
A commercial project can move from initial quote to approval in as little as three weeks, with most projects completing in one to two months after that. Building owners who give us scheduling flexibility often get the best pricing, though we routinely accommodate hard deadlines tied to fiscal years, grant requirements, or capital planning cycles.
Why hire a specialty masonry contractor instead of a general contractor?
Masonry restoration requires specialized knowledge of mortar chemistry, historic building techniques, and proper sequencing that general contractors typically do not possess. Incorrect mortar or repair methods can accelerate deterioration and cause irreversible damage. We self-perform all masonry work with our own crews, who hold certifications in lime putty restoration, stone patching, and products from manufacturers like US Heritage, Sika, Tremco, and Prosoco.
What's the difference between masonry repair and masonry restoration?
Masonry repair addresses isolated damage such as cracked mortar or a few deteriorated bricks. Masonry restoration is a comprehensive approach that returns an entire facade or structure to its original condition, addressing systemic deterioration and often involving historically accurate materials and methods.
What states and cities does TNT serve?
We serve commercial building owners throughout Iowa, Wisconsin, Minnesota, and Illinois. Our crews are based in eastern Iowa and travel routinely throughout all four states. We will travel beyond these states for the right project scope or owner.
How do I request an estimate or assessment?
Submit a request through our website, use the chat feature, or call us directly. Your request is reviewed, an estimator is assigned, and an on-site visit is typically scheduled within one to two weeks, with a proposal delivered approximately two weeks after the site visit.
Does TNT do residential work?
No. We do not perform work on homes or residential properties. We are an exclusively commercial masonry restoration contractor, and our crews, equipment, certifications, and processes are built for commercial, institutional, historic, and industrial buildings.
What types of buildings does TNT work on?
We are a commercial-only masonry restoration contractor. We work on commercial properties, churches, courthouses, government buildings, schools, universities, multifamily housing, healthcare facilities, and industrial buildings. We do not perform residential work of any kind.
What is tuckpointing?
Tuckpointing is the process of removing deteriorated mortar from the joints of a masonry wall and replacing it with new mortar to restore structural integrity and weatherproofing. It is one of the most common and critical commercial masonry restoration services, preventing water infiltration that leads to far more costly damage over time.
