Commercial Tuckpointing & Masonry Restoration in Des Moines, IA

Tuckpointing is vital in Des Moines due to the city's extreme seasonal temperature shifts, which cause mortar to expand and contract. By replacing deteriorated joints with specialized mortar, TNT prevents moisture from entering the building envelope.

Common signs include crumbling mortar, "spalling" (where the brick face pops off), and white powdery salt deposits known as efflorescence. In older neighborhoods like Sherman Hill, periodic inspections are recommended.

TNT has restored Des Moines City Hall and the Police Station, the Fort Des Moines Monument, and Park Avenue Elementary School. East of the city we restored the Jasper County Courthouse in Newton. Those are civic and institutional buildings with the documentation, coordination, and public-access requirements that come with them.

Yes. Government and institutional masonry is a core part of our work, from downtown through the capitol complex. We are set up for the procurement, documentation, and scheduling that public projects require, and our completed Des Moines work is almost entirely civic.

Parapets, copings, cornices, and window heads. Those details move the most and take the most weather, and they usually fail well before the damage is visible from the sidewalk. Our assessments start at the roof line for that reason, not at eye level.

Yes. Our central Iowa crews work Des Moines, West Des Moines, Ankeny, Urbandale, and Polk County, and our completed work here includes City Hall, Fort Des Moines and Park Avenue Elementary. We are a trusted local presence in the capital, not a contractor passing through.

Those districts are century-old load-bearing brick laid with soft, lime-based mortar. Mortar is meant to be the sacrificial element, failing before the brick does. Repoint with hard Portland mortar and you reverse that: the joint becomes stronger than the masonry around it, so when the wall moves the brick face spalls instead. Mortar has to be matched to the original in strength and composition, not just color.

Before winter, if the choice is yours. A joint that is just starting to recess in the fall can be an open, water-holding joint by spring. Our exterior season runs roughly mid-February through the end of November, so the assessment is best done the season before the work, which also gives time to budget it properly.
