Reducing Expansion Joint: Types, Uses, and Benefits

We offer two primary configurations. Type A is a flat cap for same-plane masonry joints, used on copings and lintels. Type B is a 90° cove cap for right-angle joints, such as where a lintel meets a side wall. Both are available in stock sizes or as part of application-specific systems.

Absolutely. While renowned for its use in historic preservation, its ability to extend sealant life makes it an excellent choice for new construction. It provides long-term durability and reduces future maintenance needs for any high-quality masonry work, ensuring a lasting, protective seal from the start.

WEATHERCAP® is designed for straightforward installation by qualified masonry or restoration contractors. The soft lead cap is placed in the sealant-filled joint. We provide detailed technical information, sample specifications, CAD drawings, and installation guidance to ensure proper application for a lasting, weather-resistant seal.

Yes, WEATHERCAP® can be painted to match any desired color. If left unpainted, its lead surface will naturally oxidize to a neutral grey color that blends seamlessly with most masonry and stone, maintaining the aesthetic integrity of the structure while providing superior protection for the joint.

WEATHERCAP® is made from a soft lead composition. This material is chosen for its flexibility, durability, corrosion resistance, and ability to 'creep' or adjust to building movement without tearing. This ensures the protective seal over the joint remains intact and effective over many years.

All WEATHERCAP® products are supplied in standard 6-foot lengths to facilitate handling and installation on site. We maintain an operational supply chain and typically ship materials within 48 hours of order placement to locations across the United States, ensuring your project stays on schedule.
