Fireplace Remodel in Brentwood: Written Report, Licensed Technicians

If you live along the Decker Canyon corridor or closer to the Ventura County line approach, your fireplace remodel will typically run between $4,800 and $14,000 depending on material choices and whether you're converting from wood-burning to gas. Stone surrounds using locally sourced ledgestone or porcelain tile panels sit at the lower end. Full natural stone veneer with a custom hardwood or reclaimed beam mantel pushes higher. What many homeowners in this stretch don't budget for is the damper situation. Homes up here lose a surprising amount of conditioned air through old throat dampers that never seal properly. We include a top-sealing damper upgrade in most remodel scopes because it cuts that draft loss by roughly 90 percent, and your heating bills reflect it immediately.

The energy-efficiency side of your remodel matters more here than in flatland neighborhoods. Decker Canyon homes and properties near the Lake Sherwood area sit at higher elevations where winter nighttime temps regularly drop into the low 40s. A fireplace with a poorly sealing damper acts like an open window whenever it's not in use. During your remodel, Montgomery Chimney Services installs a silicone-gasket top-mount damper and verifies the seal with a smoke test before we close up finish work. If you're converting to gas at the same time, we handle the gas line sizing, permit filing, and final inspection. You can also explore our gas log options at /services/fireplace-gas-logs to compare vented and vent-free setups before we start.

Day one is demolition and assessment. Our technician strips the existing surround material, then inspects the firebox walls, lintel bar, and smoke chamber for heat damage or earthquake micro-cracking. Homes near the Lake Sherwood area and along the Ventura County line approach sit in Seismic Zone 4, so hairline mortar cracks are common and get repaired with refractory cement before any new finish goes on. Next, we remove the old throat damper. Most of these original cast-iron units have warped after decades of thermal cycling and no longer close flat. We measure the flue opening and fit a stainless steel top-sealing damper with a cable-operated handle mounted inside the firebox. This single upgrade changes the fireplace from an energy liability into a sealed unit when not in use.

With the structural and damper work done, we move to the remodel itself. If you're keeping a wood-burning setup, we verify clearances to combustibles meet current California Building Code for any modified opening dimensions. For gas conversions, we install the burner assembly, run the gas line to code, and confirm ignition and flame pattern before the surround goes up. The surround installation uses cement board backer over the framing, then your chosen stone, tile, or brick veneer is set with heat-rated thinset. Mantel installation follows, whether that's a floating beam, marble shelf, or painted MDF. Final step is a full function test: we light the fire, confirm draft with the new damper open, then close it and verify zero smoke bleed. If you're considering a fireplace insert instead of a full remodel, our insert options may save you 30 percent or more on the project.
