Tuck Point Masonry Repair: Techniques and Cost Explained

WEATHERCAP® enhances masonry repairs by protecting the most vulnerable part of the joint: the sealant. Its soft lead construction is installed over the sealant, shielding it from UV radiation and weather. It also flexibly accommodates building movement, preventing the sealant from tearing or checking, which is a common point of failure in standard tuckpointing and masonry repairs.

Yes, the WEATHERCAP® system is suitable for both historic restoration and new construction projects. Certain products, like the A-2 Type A cap, are specifically designated for new installations. By incorporating our joint protection system from the start, architects and builders can ensure maximum durability and weather resistance for masonry joints, extending the building's lifespan.

The primary difference is their shape and application. Type A is a flat cap designed for joints between masonry units on the same plane, such as copings or lintel tops. Type B is a 90-degree cove cap used for right-angle joints, like where a window sill meets a wall or at corner junctions. Both types provide the same patented protection for the underlying sealant.

Absolutely. WEATHERCAP® is ideal for historic buildings and is a core part of its design. It has been used on numerous national landmarks like the Washington Monument and is specified in the U.S. General Services Administration's Historic Preservation Technical Procedures. Its ability to blend in visually while protecting venerable masonry makes it a preferred choice for preservation specialists.

WEATHERCAP® is designed to be installed as an adjunct to caulk or sealant. After preparing the masonry joint, sealant is applied, and then the soft lead WEATHERCAP® strip is embedded into it. This creates a composite seal where the lead cap protects the sealant and provides a flexible, durable barrier against moisture and movement. It is supplied in 6-foot lengths for field cutting.

The system is made from a soft lead composition. This material is specifically chosen for its unique properties: it is highly flexible, has a low elastic modulus to accommodate movement without stress, and it naturally oxidizes to a neutral grey color that blends seamlessly with most masonry and stonework. This ensures both long-term performance and aesthetic compatibility.
