Fireplace Inspection in Brentwood: Written Report, Licensed Technicians

A standard fireplace inspection from Montgomery Chimney Services runs between $195 and $325 for homes in the Brentwood hills, Decker Canyon, and properties closer to the Lake Sherwood area along the Ventura County line approach. That range depends on whether you need a Level 1 visual inspection or a Level 2 camera scan, which is required any time you're selling or buying a home. Most of the residences in these areas were built between the 1970s and early 2000s with prefabricated or masonry fireplaces that have gone decades without a close look at the firebox panels or flue lining. If we find refractory cracks during the inspection, we'll document them with photos and recommend repair before they expose framing to heat transfer. You can schedule that work through our fireplace repair service without needing a second trip.

Here's where energy efficiency and damper sealing factor in. A warped or corroded damper lets conditioned air escape straight up the flue year-round. In hillside homes near Decker Canyon, where temperatures swing 15 to 20 degrees between morning fog and afternoon sun, that air loss drives up cooling costs from May through October. We include a damper function test in every inspection. If the damper doesn't seal within a quarter inch of closed, we flag it and quote a top-sealing damper replacement on the spot. Addressing the damper during the inspection visit saves you a separate service call fee and often pays for itself within two heating seasons through reduced energy waste.

The inspection starts at the firebox. Our technician examines each refractory panel for cracks, spalling, and gaps where mortar has deteriorated. In Brentwood homes built along the Ventura County line approach and up toward the Lake Sherwood area, we regularly find hairline cracks in firebox panels caused by seasonal ground movement and the temperature cycling that comes with infrequent use. Even a crack narrower than a dime can allow heat to reach combustible framing behind the firebox wall. We measure clearance-to-combustibles at multiple points because original construction in these neighborhoods sometimes placed wood framing closer to the firebox than current NFPA 211 standards allow. Any clearance violation gets documented with measurements, not just a pass-or-fail note.

After the firebox, we move to the damper assembly and the flue. The technician operates the damper manually, checking for warping, rust, and incomplete closure. A damper that sticks open even slightly creates a direct path for carbon monoxide to backdraft into your living space when wind patterns shift through Decker Canyon, which happens regularly during Santa Ana events. We then run a camera up the flue to inspect the liner for cracks, creosote buildup, and signs of moisture intrusion. The camera scan is especially important for properties near the coast-facing ridgelines where marine air accelerates corrosion inside clay and metal flue liners. You'll receive a written report with photos, a CO risk assessment, and specific next steps if we find damage that needs fireplace repair.
