Chimney Inspections in Norwalk, CA

Chimney Inspections for Norwalk Homeowners

Norwalk went from farmland to a city of tens of thousands inside a single decade. The tracts that went up through the 1950s were built quickly and to a price, and the chimneys reflect that: light masonry stacks on shallow footings, tile-lined, with minimal crown detail and no cap as standard. Seventy years on, the most common thing we find on a camera survey here is displaced flue tile. Some of that is seismic, but a good deal of it is simple differential settlement on ground that was agricultural before it was residential and was not always prepared as thoroughly as it would be today. A chimney is a heavy, rigid column attached to a light flexible house, so when the ground under one corner moves, the stack is where you see it. Look for a gap opening between the chimney and the wall of the house, or a stair-step crack in the mortar joints. Neither is necessarily an emergency, but both mean the flue inside has almost certainly moved too.

Rapid 1950s tract construction on former farmland, with differential settlement showing as displaced flue tiles and separation cracks.

An inspection is the only part of this trade that tells you something you could not otherwise know. A flue can look perfectly sound from the hearth and be cracked through two storeys up. That matters more here than in most of the country because of what the ground does. The 1987 Whittier Narrows earthquake put hairline shears through masonry across the Whittier and Pico Rivera area that have quietly widened ever since, and the Portuguese Bend slide is still moving under parts of Rancho Palos Verdes today. Add the ordinary rate of settlement in the postwar tracts built on old dairy and farm land in Cerritos, Artesia and Norwalk, and cracked flue tiles are common in houses that have never had a bad fire. We also do a lot of point-of-sale work. A Level 2 inspection is what a lender, an insurer or a careful buyer's agent will ask for, and a written report with photographs settles the question rather than starting an argument.
