Kirkwood's Brick Is Old. The Mortar Holding It Together Is Older. And It Needs the Right Repair.
Kirkwood is one of the oldest communities in St. Louis County — and its housing stock reflects that history. Walk down Woodbine Avenue, Argonne Drive, or Taylor Avenue and you’re looking at brick homes that were built before World War II. Many of the most distinctive properties in Kirkwood’s historic neighborhoods were constructed in the 1910s, 1920s, and 1930s — which means their mortar joints have been weathering Missouri winters for 80 to 110 years.
At that age, mortar deterioration isn’t a question of if — it’s a question of how much. And in Kirkwood’s older neighborhoods, the answer is often: more than homeowners realize until they get a professional assessment.
What makes tuckpointing in Kirkwood specifically different from tuckpointing in a newer St. Louis suburb isn’t the process — it’s the materials. Kirkwood’s pre-war brick was manufactured to different specifications than modern brick. It’s softer and more porous. It was laid with lime-based mortars that have the flexibility to move slightly with temperature changes — absorbing the stress of freeze-thaw cycles without transmitting it to the brick.
When that aged lime mortar is replaced with modern Portland cement mortar — harder, less flexible, and stronger than the brick itself — something has to give when the wall moves. And it won’t be the new mortar. It’ll be the brick. Faces spall. Edges crack. The very repair meant to preserve the wall begins destroying it.
This is why ECI’s approach in Kirkwood starts with a material assessment before any work begins. We identify your brick type, evaluate the existing mortar composition, and select a replacement mortar specifically matched to your property. In Kirkwood’s pre-war neighborhoods, that almost always means a lime-based formulation. The repair takes a bit longer to cure than modern cement. But it works with your historic brick rather than against it — and it lasts.
Common Masonry Issues in Kirkwood's Older Neighborhoods
Deeply Recessed Mortar Joints
In Kirkwood’s oldest properties, mortar has sometimes recessed so deeply that it’s no longer protecting the brick edge. Water infiltrates not just through the joint but along the brick face itself, accelerating deterioration significantly.
Efflorescence
The white staining that appears on brick faces throughout Kirkwood’s older neighborhoods is efflorescence — mineral salts carried to the surface by water migrating through the wall. It’s cosmetically unappealing but more importantly it’s evidence that water is moving through the wall system. Tuckpointing stops that movement.
Chimney Mortar Deterioration
Kirkwood’s older homes feature brick chimneys that have been exposed to weather from all four sides for decades. Chimney mortar deteriorates faster than wall mortar due to this full weather exposure — and a failing chimney is a specific fire and water safety concern beyond just aesthetics.
Porch and Foundation Brick
The brick on Kirkwood’s older front porches and foundation courses is often in worse condition than the main wall — exposed to ground moisture from below and weather from above simultaneously.

Frequently Asked Questions — Tuckpointing in Kirkwood
Why is mortar selection so important for Kirkwood's older homes?
Kirkwood’s pre-war brick is softer and more porous than modern brick, and was laid with lime-based mortars designed to flex with seasonal movement rather than rigid modern Portland cement. Using Portland cement to repair this historic brick forces stress into the brick itself — causing spalling and cracking. ECI always assesses brick type and existing mortar before selecting a repair mortar for Kirkwood properties.
How do I know if my Kirkwood home needs tuckpointing?
Signs include recessed or crumbling mortar joints, white mineral staining on brick, cracks between bricks rather than through them, and any interior moisture near exterior walls. On Kirkwood’s older homes, an inspection every 10-15 years is a sound maintenance practice even without visible symptoms.
