Bathroom Remodeling in Altadena
Altadena bathroom remodels that check the joists under a heavy tub first, with ember rules for the window and vent confirmed by the county.
Will the floor hold a cast iron tub once it is full and someone steps in? That question belongs on an Altadena walk-through, and the answer sits under the tile. We open the floor, look at joist size and the bearing at each end, and press an awl into the wood near the drain. Some Altadena lots sit in mapped fire hazard zones, so the fan cap and window get checked as well.
Weight and the joists below
A filled tub puts its weight on a short stretch of a few joists, and that load travels to whatever holds those joists up. We check span, spacing and any sag, then follow the joists to their bearing on a wall, girder or post. Rot near the drain, or a notch cut deep for an old pipe, changes the plan. A weak joist gets doubled or sistered full length, and blocking spreads the tub load across its neighbors. If a post or pier under the room has settled, that is quoted separately.
Ember rules for the vent and the window
Where a lot is mapped, ember-resistance rules can reach the parts of a bathroom that meet the outside. A replaced window would use double glazing where one pane is tempered, or a fire-rated assembly. The fan duct gets a metal cap with a damper. Los Angeles County reviews permits for unincorporated Altadena and confirms what applies to the parcel. We look up the mapping before any window or cap is ordered. Inside, the order stays the same: framing repairs, rough plumbing, a tested pan, then tile.

Bathroom Remodeling in Altadena: questions
Soft or stained sheathing is cut out to firm wood and replaced with new plywood fastened to the joists. Under a heavy tub, any joist with rot or a deep old notch is sistered full length or doubled. The county sees structural repairs on the permit set, and the quote shows them as separate lines.
The base under the tile falls toward a drain that clamps the membrane, and that membrane climbs the walls past the showerhead. Before tile, the pan is filled with the drain plugged and watched for any drop. A failed grout joint then sends water down the membrane and away from every stud.
Yes, within what the joists and the drain fall allow. A moved fixture brings its vent along, and a heavy tub set on a new wall may need the joists under it reinforced. The county reviews the new layout, and the rough lines are inspected with the walls open.
