Why all pre-cast chimneys should be inspected prior to close of escrow
Here is a quote from a property inspection report done by a property inspection company last week on a home in Lake Forest:
“Pre-cast concrete chimneys were built in factories and then trucked to a site and erected, as distinct from masonry chimneys that are built on site with individual bricks and mortar. In this respect, pre-cast chimneys are unique. However, like all masonry chimneys, they are vulnerable to seismic activity, but unlike masonry chimneys they are also subject to cracks that are induced by the interaction of moisture and a chemical additive that causes the reinforcing steel within the chimney to expand and crack the chimney walls. Such cracks can be small, but they are nonetheless subject to stringent repair methods. However, if any crack penetrates the chimney wall it may be difficult to repair the chimney without costly repairs or replacement or possibly relining the chimney. For this reason, we recommend that all pre-cast chimneys be further inspected/video scanned or certified by a specialist before close of escrow.”
