During every cleaning, we perform a visual inspection that can identify common repair needs. Signs that indicate you need more than just cleaning include cracked or deteriorating mortar joints, damaged flue tiles, rust on your damper, or water stains around your fireplace. White staining on your chimney exterior (called efflorescence) is a clear indicator of moisture problems that typically require repair work. Similarly, if your chimney cap is damaged or missing, you’ll need replacement to prevent water damage and keep animals out. We also check for structural issues like leaning or separation from your house, problems with your chimney crown, or damaged flashing where your chimney meets your roof. These issues don’t get better on their own and can lead to expensive problems if ignored. The good news is that catching them early during routine cleaning usually means simpler, less expensive repairs.
