Why Hillstar
What Hillstar Brings to an Altadena Bathroom
A bathroom rebuild in a 1920s Altadena house is mostly about what sits under the surface — and we've opened enough of these floors to price that honestly.
County Permits, In-House
Altadena is unincorporated LA County, so the permit desk is the County's — not LADBS and not Pasadena. We file, answer corrections, and book each inspection.
Old-Pipe Realities
Galvanized supply, cast-iron waste, and lead-solder joints on pre-1986 copper get scoped during design and put in writing before demolition starts.
Waterproofing Built to Last
Membrane behind every wet surface, pre-sloped pans, sealed transitions — engineered for decades, not for the final walkthrough.
A Schedule in Writing
Milestones are set at design and tracked through the County's final inspection. You always know the next step.
Itemized Quotes
Each line is priced before work begins. If the subfloor changes the scope, the change is documented and approved first.
One Crew Throughout
The team that designs your bathroom is the team that builds it — a single contact from first visit to final walkthrough.
Our process
From First Visit to Final Inspection
Four steps, each one owned by us rather than by the homeowner.
1
Walk the Bathroom
We measure the room, check the panel and the plumbing stack, and listen to what you actually want changed.
2
Design & County Submittal
Drawings, material selections, and the LA County Building & Safety filing — prepared and submitted by us.
3
Demo, Rough-In, Tile
Plumbing and electrical rework, membrane waterproofing, and tile setting by our own crew, inspection by inspection.
4
Punch List & Warranty
A final walkthrough together, every open item closed, and a written workmanship warranty behind the finished room.

FAQ
Altadena Bathroom Remodel — FAQ
The questions Altadena homeowners ask most: the County permit desk, old-house plumbing, foothill specifics, and what a realistic budget looks like.
Who issues bathroom permits in Altadena?
LA County does. Altadena is unincorporated — not the City of Los Angeles and not Pasadena — so building, plumbing, and electrical permits run through the County's Building and Safety office, and inspections are scheduled there as well. We handle that path end to end, submittal through final sign-off.
My house is from the 1920s. What should I expect behind the tile?
Plaster-and-lath walls, galvanized supply lines, a cast-iron stack, and — on pre-1986 copper — solder joints that may carry lead. None of it stops a remodel. We open the floor early, document what's actually there, and price any repipe or subfloor repair in writing before tile is ordered.
Do foothill properties change the scope?
Sometimes. On blocks climbing toward the San Gabriels, drainage and slab conditions can affect a ground-floor bathroom, and homes rebuilt after the Eaton Fire follow the County's rebuild guidance. The first site visit tells us which of these applies on your street.
When does an Altadena bathroom project need a permit at all?
Swapping a faucet or a vanity in place usually doesn't. Moving a drain, converting a tub to a walk-in shower, opening a wall, adding a circuit, or cutting in new ventilation does. Where a permit applies, we pull it and meet the County inspector ourselves.
What waterproofing standard do you build to?
A continuous membrane — sheet or liquid-applied — behind every wet surface, with pre-sloped pans, sealed corners, and curb or curbless details built to hold water for the long run. Exhaust is ducted outside and sized to the energy code. It's the part you never see, and it decides how long the bathroom lasts.
What does an Altadena bathroom remodel cost?
Scope decides it: a finish-level refresh, a full gut of a hall bath, and a primary-suite rebuild are three different projects. What stays constant is the format — an itemized written quote after we've seen the room, with old-plumbing contingencies priced up front instead of surfacing mid-build.
