Maintaining and repairing masonry chimneys and walls above the roofline is crucial for keeping your home waterproof. This work should be done before or during roof replacement to avoid damaging a new roof. Leaks around chimneys are often caused by deteriorating brick or stonework rather than roofing or flashing issues. Re-pointing with Type S or Portland mortar not only seals and strengthens the masonry but also prevents costly rebuilds in the future. Applying a masonry sealer helps maintain mortar joints and the chimney crown. Additionally, we offer installation services for both stock and custom-fabricated steel and copper chimney flue caps.
