Fireplace Inspection in Woodland Hills: Written Report, Licensed Technicians

A homeowner on a quiet street off Tujunga Village called us last winter after converting from a wood-burning fireplace to vented gas logs. The original masonry firebox was built in the late 1950s, and he assumed the switch to gas meant fewer problems. But after a couple of months, he noticed a faint smell when the logs ran for more than an hour. His wife started getting headaches on evenings they used the fireplace. He wasn't sure if the gas logs were installed wrong or if the chimney itself was the issue. What he described is something we hear regularly from Studio City homeowners who've made this exact conversion without getting the firebox inspected first.

Gas log sets produce carbon monoxide just like wood fires do, but the combustion byproducts behave differently inside an aging masonry chamber. When a firebox has hairline refractory cracks or a damper that no longer seals properly, CO can migrate into wall cavities and living spaces instead of venting up the flue. Along the Ventura Boulevard flats and the Moorpark Street corridor, many homes share the same 1950s single-wythe brick construction. These fireboxes were sized and lined for wood fires. Dropping a gas log set into one without verifying clearance-to-combustibles and refractory integrity is a common but serious oversight. That's what prompted his call to Family Home Chimney Experts.

We scheduled a Level 2 inspection, which NFPA 211 requires whenever a fireplace's fuel type changes. Our technician ran a camera scan through the full flue and examined the firebox panel by panel. Three refractory panels had cracks wide enough to expose the brick behind them, and the mortar joints in the smoke chamber had eroded to the point where gaps were visible without magnification. The damper blade was warped from decades of heat cycling and couldn't close flush. That gap alone was costing him conditioned air every day the fireplace sat unused. The gas log set itself had been installed with inadequate clearance to the side walls of the firebox, violating manufacturer spacing requirements by over an inch.

We documented every deficiency with photos and measurements, gave him a written report, and outlined a repair sequence: refractory panel replacement, smoke chamber parge coating, damper replacement with a top-mount unit, and repositioning the gas log set to meet clearance specs. After the fireplace repair work was completed, we re-inspected and confirmed the system met NFPA 211 standards for a gas-appliance-connected flue. No more headaches, no more smell. If you've converted to gas logs in a Tujunga Village or Moorpark Street corridor home and skipped the inspection step, call Family Home Chimney Experts at the number above. One visit can tell you whether your firebox is safe for the fuel it's actually burning.
