When to get in touch.
- Brick faces flaking or breaking away
- Open mortar joints or loose stone
- Localized masonry damage around the chimney or fireplace
A considered starting point.
Understand the existing system
Identify damaged units and joints and assess the extent of deterioration.
Define the right scope
Consider water entry and material compatibility before choosing a repair approach.
Plan the details
Plan replacement brick or stone, mortar color and profile, and the transition to existing work.
Before you decide.
A hard replacement mortar is not automatically the best choice for older, softer brick. Material compatibility matters. If your home is in a historic district, ask the local preservation or building office about exterior-work requirements before the scope is finalized.
Your questions, answered.
Can you match old St. Louis brick?
Matching depends on availability, dimensions, texture, and weathering. A repair consultation can identify options and explain how close the new material may be to the existing masonry. An exact match should not be assumed.
What is spalling?
Spalling is the loss or flaking of a masonry unit’s face. Moisture and freeze-thaw cycles can contribute, but the specific cause and extent need evaluation before repairs are chosen.
Homeowner guidance: Chimney Safety Institute of America. Appliance installation and operation must follow the specific manufacturer’s instructions. Service scope and availability are confirmed before scheduling.
