Preserving History
Historic buildings are the foundation of what many of our local towns throughout the United States were built on. Those local towns, their communities, the local governments and historical societies are passionate about preserving that history, so we feel especially honored every time we’re chosen to be a part of the process of restoring historic properties.
What We Do Best
Restoring a historic building means understanding the original materials, construction methods, and architectural intent — then matching them precisely. Our team brings decades of hands-on preservation experience to every project, working with historical societies, architects, and property owners to maintain the character and structural integrity of buildings that matter to their communities.

FAQs
Do you have examples of historic building restoration?
Yes. Roughly half of our work is historic preservation, including churches, courthouses, and government buildings that require period-appropriate materials and techniques. The portfolio page features many of these projects with detailed photography.
How does deferred masonry maintenance increase long-term costs for public buildings?
Water that enters through failed mortar joints and caulking damages the wall system from the inside out, affecting insulation, structural steel, interior finishes, and building systems. What starts as routine repointing can become a full envelope reconstruction if deferred too long.
How does TNT minimize disruption to public buildings during restoration?
We plan access, scaffolding, and work sequencing around building operations, public access points, and event schedules. Pre-construction coordination with facility managers ensures the building remains functional and accessible throughout the project.
Can masonry restoration be phased across multiple budget cycles or fiscal years?
Yes. We regularly work with government entities to phase large restoration projects across multiple fiscal years, prioritizing the most critical repairs first and planning subsequent phases around approved budgets and funding availability.
When should a building owner or facility manager request a masonry investigation?
Request an investigation when you observe recurring water infiltration, cracking, spalling, efflorescence, or mortar joint failure, or when planning a capital improvement budget for masonry restoration. Investigating before damage spreads prevents more expensive repairs later.
How does TNT help with capital planning for masonry work?
We help owners understand what work is needed now versus what can be deferred, identify the highest-priority items, and structure project phasing to spread costs over time. Projects range from $2,500 to the millions, and we work with owners to align scope with budget.
Why should I get a masonry assessment before budgeting for repairs?
Without a proper assessment, budgets are based on assumptions that often underestimate or mischaracterize the actual conditions. A masonry investigation identifies what work is truly needed, allows owners to prioritize critical items, and reduces the risk of unexpected costs once work begins.
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.
