Bathroom Remodeling in Altadena
Outlet and circuit checks first, fire-area vent choices, a county permit set and a membrane tested before tile.
A three-light tester pushed into the outlet beside the sink is the first probe in an Altadena bathroom. It shows whether the circuit is grounded and whether a ground-fault device protects it, and an older circuit can fail that test without anyone noticing. What the tester reports sets the electrical line of the quote before tile, vanity or fixtures are discussed. Fire hazard maps cover part of Altadena, so the vent choices need thought too.
Fire-area choices for the exhaust duct
If the address is mapped as a fire hazard area, the exhaust fan's outlet is one of the openings embers can use to get into the house, so the cap and its screen matter. We plan a metal duct with a noncombustible cap and fine mesh, and the county building department confirms what applies to the address. The fan itself is sized to the room and runs on a switch or humidity sensor you choose, so steam leaves the room before it settles into the walls and ceiling.
Waterproofing and the permit set
Because no city government covers Altadena, the county building department is the one that reviews this permit. On the drawings go the new shower drain, the membrane that wraps the walls and floor, and any electrical changes the tester turned up. Once the membrane is on, we flood the pan and let the water stand before any tile is set. A leak found then is a small repair. One found after tiling means opening finished walls. Inspections come in order: rough plumbing and wiring while the walls are open, the membrane test before tile, and the final after the fixtures are set.

Bathroom Remodeling in Altadena: questions
A bonded sheet membrane or a liquid-applied coat covers the cement board, wraps up the walls and runs across the pan to the drain. Seams and corners get reinforcing tape and extra membrane. The pan is flooded, the water line is marked, and tile starts only when the line has not moved.
It can. In a rebuild the shower floor sits lower in the new framing, and the membrane runs continuous from that floor up the walls. The drawings show the depth before framing starts, so the plumber and the tile setter work to the same number.
Pipes exposed by demolition are judged on the spot. Supply lines that are corroded, galvanized or past their working life are replaced while the wall is open, and a drain with a crack or a poor slope is reworked. What stays in the wall is pressure tested, and the written scope records each finding.
