Fireplace Remodel in Pasadena: Written Report, Licensed Technicians

A fireplace surround swap with new tile or stacked stone typically runs between $4,500 and $9,000 in the Pasadena foothills, depending on material choice and whether you're also replacing the mantel. That's the cosmetic side. But in La Crescenta and Sunland, where many homes date to the 1950s and 1960s, the firebox often sits behind a smoke chamber with exposed, rough-mortared corbeled bricks. Those uneven surfaces trap creosote and restrict draft. Code requires a smooth smoke chamber before you can modify an opening or convert to gas, and parging that chamber with a refractory sealant adds $800 to $1,500 to your project. Skip it, and you'll fail inspection.

Flue lining is the other budget item that surprises homeowners. If your existing clay tile liner is cracked from decades of thermal cycling or from the seismic activity common in the foothill corridor near Tujunga, a new stainless steel liner runs $1,200 to $2,500 depending on flue height and diameter. When you're converting from wood to gas during a remodel, the liner diameter usually changes, so relining isn't optional. We include a Level 2 camera inspection before quoting any remodel, which means you know the full scope before we pull a single tile off the surround. If gas conversion interests you, take a look at our gas log installation options for a simpler alternative.

Every remodel starts with the camera. Our technician feeds a CSIA-standard video scope up through the damper and into the smoke chamber to document the condition of the liner, the corbeled brickwork, and any mortar gaps. In La Crescenta and Sunland homes built on hillside lots, we frequently find hairline cracks in clay flue tiles caused by ground movement that you'd never see from below. If the liner needs replacement, we size a new stainless steel liner to match the BTU rating of whatever appliance you're installing, whether that's a gas insert or a new EPA-certified wood-burning unit. The old liner gets removed section by section from the top down. For smoke chamber parging, our tech applies ChamberTech 2000 refractory morite in thin layers with a trowel and specialized brushes, building a smooth, insulated surface that improves draft and meets NFPA 211 clearance requirements.

Once the flue system passes inspection, the visible remodel begins. We demo the existing surround down to the framing or masonry substrate, inspect for heat damage to nearby studs, and install cement board as a non-combustible backer. Stone veneer, porcelain tile, or natural marble goes up next. Mantel installation follows, with clearance heights dictated by Pasadena building code: a minimum of 12 inches from the firebox opening for combustible mantels. If you're adding a fireplace insert rather than a full custom surround, we handle the framing and finishing around the unit so everything fits flush. After final inspection, we walk you through damper operation, gas valve location if applicable, and maintenance schedules so the new setup lasts.
