Slate Chimney Caps: Choosing the Best Options for Your Home

It's a patented soft lead strip used with sealant in masonry joints. It protects the sealant from environmental stress and accommodates building movement to prevent leaks. This extends the life of the joint seal, making it ideal for both new construction and historic restoration projects.

Type A is a flat cap for joints between masonry units on the same plane, like coping top joints. Type B is a 90-degree cove cap for right-angle joints, such as where a projecting lintel meets a vertical wall, or at cornices and window sills.

Yes, our lead joint caps can be painted to match the surrounding masonry or architectural elements. If left unpainted, the lead oxidizes to a neutral grey color that naturally blends in with most stone and masonry, providing a subtle, clean finish.

Its soft lead construction is ideal for historic structures, which often experience settlement and movement. The system protects vulnerable, aging masonry joints from moisture penetration without stressing the material. It is specified in GSA Historic Preservation Technical Procedures for this reason.

All WEATHERCAP® products are supplied in standard 6-foot lengths. This allows for easy transportation and handling on the job site, and they can be cut to fit specific joint dimensions as needed during installation. Most orders ship within 48 hours.

No, WEATHERCAP® is designed as an adjunct to caulk or sealant, not a replacement. It is installed within the sealant-filled joint to cover and protect it, reducing the effective opening size and shielding the sealant from UV exposure and weather, thereby prolonging its life.
