Rolling Hills Estates chimneys and the draft question
Many houses here were expanded long after they were built, and an added family room or new dual-pane windows can leave the old fireplace starved for air. Run a large range hood in an open kitchen and it will pull smoke down the chimney and out across the floor. Before anyone talks about raising the chimney, we measure house pressure with a manometer. Whatever the stack looks like, the first job is the same: watch which way the smoke goes at the damper, then work out why.
