ADU Company in Crestline, CA
Kitchen remodeling in Crestline means working inside aging mountain cabins where 1960s wiring, single-wall plumbing runs, and warped pier-and-beam floors collide with modern code and snow-load realities. Most homes here were built as weekend escapes, not year-round kitchens, so the work rarely stops at cabinets and countertops. Casita ADU Builders has served Crestline since 2013, and we plan every kitchen around freeze protection, fire-safe materials, and the tight access that comes with winding mountain roads. Call (877) 658-7475 for a free estimate on a kitchen that actually works up here.
Why Crestline Homes Are Different
Crestline sits inside the San Bernardino National Forest at roughly 4,500 feet, and that single fact reshapes nearly every remodeling and ADU decision. The housing stock is dominated by mid-century and 1960s-80s mountain cabins and second homes: small footprints, wood siding, pier-and-beam or slab-on-grade foundations on sloped lots. Many still carry original knob-and-tube wiring or undersized 60-amp panels that cannot legally support a modern kitchen, let alone an ADU. Septic systems on older parcels often need evaluation before any square footage gets added. Winter brings real snow and ice, so any exterior wall opened for plumbing or electrical work has to be insulated and sealed differently than a flatland build would be. Dry-season fire risk means San Bernardino County’s High Fire Severity Zone requirements shape material choices: ember-resistant siding, Class A roofing, and defensible-space clearances around the structure. Steep driveways and narrow roads off Lake Gregory Drive and around the Top Town area also mean material deliveries get staged differently, sometimes with smaller trucks or hand-carry for the last stretch. None of this is impossible. It just means the contractor has to know the mountain before the first permit gets pulled.
Our Main Crestline Services
Most Crestline homeowners call us about two things: building an ADU on a tricky mountain lot, or gutting and rebuilding a bathroom in a cabin that was never designed for daily use. Here is what each involves up here.
ADU Builders in Crestline
Building an ADU in Crestline is a forest-build exercise more than a backyard project. Fire-defensible space, tree clearance, driveway grade for emergency access, and snow-load roof design all come before floor-plan talk. We work across leading prefab manufacturers like Abodu, Cover, and Dvele, plus Tuff Shed conversions for a faster, lower-cost path. James Hardie fiber-cement exteriors hold up to mountain weather and meet the fire-resistance bar lenders and inspectors want to see. Read the full Crestline breakdown here: ADU Builders in Crestline.
Bathroom Remodeling in Crestline
Bathrooms in Crestline cabins are often the first room to fail: cast-iron drains rusting out, single-wall plumbing freezing in January, subfloor rot where snowmelt tracked in for decades. We handle the full gut-and-rebuild, including freeze-protected supply lines, sealed and insulated exterior walls, proper ventilation for a humid mountain climate, and finishes that suit a cabin without pretending it’s a suburban tract home. Our in-house teams do the work under one contract. Details are here: Bathroom Remodeling in Crestline.

Kitchen Remodeling in Crestline
Kitchen remodeling in Crestline usually starts with a structural reality check: the original 1960s cabin wiring will not carry a modern appliance load, the floor has settled on a sloped lot, and the plumbing was never insulated for real winter. We plan the whole job around those conditions. From freeze-protected supply lines to fire-resistant Kitchen Remodeling materials and cabinetry that handles temperature swings, a Crestline kitchen has to be built for the mountain, not just for looks.
Full Cabin Kitchen Renovation
Signs you need it
Your panel is still 60 amps, outlets spark when you plug in a toaster, or cabinet doors no longer close square because the floor has moved.
What it costs in Crestline
A full cabin kitchen renovation in Crestline typically runs $38,000 to $65,000 depending on layout changes, panel upgrades, and how much rot we find once walls are opened.
How we do it
We demo to studs, upgrade the panel and wiring, re-plumb with freeze-protected lines, level or reinforce the floor, then install cabinets, counters, and appliances, pulling permits and passing inspections at every stage.
Countertop and Cabinet Replacement
Signs you need it
Laminate is peeling from years of temperature swings, or drawer slides and hinges have given out and the cabinet boxes are still sound enough to keep.
What it costs in Crestline
Countertop and cabinet replacement in Crestline typically runs $12,000 to $28,000 depending on material grade and whether we are refacing or replacing boxes.
How we do it
We measure for new cabinets or reface existing boxes, template and install countertops, adjust for sloped floors with a level base, and reconnect plumbing with insulated supply lines.

Is kitchen remodeling in Crestline worth it on a second home?
Yes, if the house will ever be lived in for more than weekends. A mountain kitchen that can’t handle real cooking or winter freezes drags down resale and rental income, and buyers up here notice deferred maintenance immediately.
What kitchen materials hold up best in the Crestline climate?
Solid plywood cabinet boxes handle temperature and humidity swings better than particleboard. Quartz or granite counters resist cracking better than laminate. We spec materials suited to freeze-thaw cycles, not showroom conditions.

Inside, we build kitchens and baths around a range of cabinet, countertop, and fixture brands matched to the cabin or the ADU’s manufacturer, including prefab partners like Abodu, Cover, and Dvele.

What Crestline Customers Say
"Detached unit in the back yard. Utilities trenched, separate meter, and it passed final on the first inspection."
— Robert Gallagher"Garage conversion to a one bedroom unit. He handled the plans, the city submittal, and every round of corrections. Took six months from first meeting to final inspection and he never once made the permit process my problem."
— Aisha Prince"Knew the local setback and parking rules cold, which saved us from designing something that would never have been approved."
— Maria Martinez
