Brentwood houses and the way they breathe
Big Brentwood houses often have two or three fireplaces sharing one masonry stack. When one fire is lit, smoke can drift down a neighboring flue into another room, a problem that looks like a leak but is really a short flue partition or uneven flue heights at the top. A fireplace competes with every fan and vent in the home for air, so we note what else runs while the fire burns before blaming the chimney for chimney repair.
