Chimney repair, cleaning and fireplace service in Thornton Park

Rust on the damper, on the firebox floor or on the metal of a fireplace insert is a sign of moisture, and in Thornton Park, an Orlando neighborhood with official city boundaries, our technicians look at rust as a symptom to trace rather than a stain to scrub. Where is the water coming from, and how long has it been there?

There are two main sources. Rain entering from above, through a missing or damaged cap, a cracked crown or failed flashing, runs down the flue and lands on the damper and firebox. Humidity is the other. Humid outside air moving down a chimney that is open to the sky, especially when the air conditioning pulls air through the house, can condense on cool metal inside the fireplace.

Soot mixed with that moisture becomes acidic and speeds up the corrosion. A rusted damper eventually stops sealing or seizes shut. Rust on the firebox floor can stain the firebrick and point to standing water. On a factory-built fireplace, rust on the metal firebox or chimney pipe can weaken parts that must stay sound, and the maker's parts list decides what can be replaced.

The fix starts at the source. A properly sized cap stops rain entering the flue. A crown repair or new flashing stops water moving into the masonry. A top-sealing damper can close the flue at the top against humid air when the fireplace is not in use. Then the damaged parts are cleaned, repaired or replaced, and a sweep removes the acidic soot.
