The Hidden Dangers of Waiting
A small leak might seem harmless at firstjust a bit of water near the fireplace or discoloration on the bricks. But water is one of the most damaging forces to any masonry structure. Once moisture enters, it expands during freezing temperatures and begins to erode the brickwork and mortar from the inside out.
Creosote buildupanother commonly ignored issueacts like fuel in your chimney. All it takes is one stray spark to ignite it, causing a fast-moving and devastating chimney fire.
The longer these issues are left untreated, the more expensive and invasive the repairs become. In extreme cases, full chimney reconstruction or flue replacement may be requiredboth of which are far more costly than preventive maintenance.
