ADU Company in Crestline, CA
Kitchen remodeling in Crestline means working inside cabins and older mountain homes where walls hide surprises from the 1940s through the 1970s, and where every material choice has to answer to snow load, freeze-thaw cycles, and wildfire code. We’re Costa Mesa ADU Builders, and we’ve served Crestline since 2012. We handle kitchen remodels, ADU construction, and bathroom work under one contract, so a homeowner adding an ADU for rental income can refresh the main house kitchen in the same project phase without coordinating a second contractor. Call (833) 589-8273 to talk through your lot and your numbers.
Why Crestline Homes Are Different
Crestline sits at roughly 4,500 to 5,000 feet in the San Bernardino Mountains, and the housing stock reflects a century of cabin construction that never anticipated today’s code requirements. Most homes are wood frame, single story, and small, put up between the 1920s and 1970s on pier-and-beam or shallow foundations cut into slopes. When we open a kitchen wall in Crestline, we’re usually looking at dimensional lumber that has settled, wiring that predates modern panel capacity, and floor framing that was never designed for the weight of stone counters or a kitchen island. Snow loads drive roof design, and freeze-thaw cycles punish any exterior penetration. The other reality: Cal Fire’s wildland-urban-interface rules govern defensible space, exterior material choices, and access, so a kitchen remodel that touches an exterior wall can trigger Chapter 7A fire-resistant construction requirements. None of this is optional. We plan for it from the first site visit.
Our Main Crestline Services
Two services drive most of our work in Crestline: ADU construction and bathroom remodeling. Both run into the same mountain-lot realities – steep grades, tree roots, older foundations, and fire-code setbacks – and both benefit from having one contractor accountable from the first structural cut to the final interior finish.
ADU Builders in Crestline
Adding an ADU on a Crestline lot almost always starts with a geotechnical report, because the steep, tree-rooted terrain determines whether we’re building on a standard frost-depth foundation, helical piers, or a retaining-wall-supported pad. Cal Fire’s 100-foot defensible space requirement and Chapter 7A exterior standards become the make-or-break cost item on most projects. We compare prefab brands like Boxabl, Plant Prefab, and Tuff Shed against site-built framing, so the recommendation fits your specific slope, snow-load, and access constraints. Full details on our ADU Builders in Crestline page.
Bathroom Remodeling in Crestline
Bathroom remodels in Crestline cabins often mean working within a 5-by-8 footprint with framing that has settled unevenly, cast-iron plumbing that has corroded, and subfloor sheathing compromised by decades of freeze-thaw moisture. Ventilation matters more at 5,000 feet, because a poorly vented bath fan pushes moisture into attic insulation during winter and invites mold. We handle the full interior scope in house, from rough plumbing to tile and fixture set, under one contract. See our Bathroom Remodeling in Crestline page for specifics.

Kitchen Remodeling in Crestline
Kitchen remodeling in Crestline usually means bringing a cabin-era kitchen up to modern function without pretending the structure underneath is newer than it is. Homes built from the 1920s through the 1970s on pier-and-beam or shallow foundations often need floor framing reinforcement before new cabinets, stone counters, or an island can go in. Snow-load-rated roof penetrations, freeze-resistant supply lines, and fire-resistant exterior details all come into play when a remodel touches an outside wall or adds a range hood vent. We manage the whole job from demo to finish under one contract, and our in-house Kitchen Remodeling capability means the primary residence can be updated in the same phase as a new ADU, cutting total disruption and eliminating subcontractor handoffs.
Cabinet and Countertop Replacement
Signs you need it
Cabinet boxes that have swollen from years of mountain humidity swings, drawer slides that bind, or laminate counters that have delaminated at the seams all signal it’s time.
What it costs in Crestline
Full cabinet and countertop replacement on a typical Crestline cabin kitchen runs $18,000 to $42,000 depending on cabinet line, counter material, and whether the existing footprint can be reused.
How we do it
We pull permits, demo to framing, sister or reinforce floor joists where the old structure has settled, set new cabinets level on the existing slope floor, template and install counters, and reconnect plumbing and fixtures.
Full Kitchen Gut and Rebuild
Signs you need it
Floor framing that deflects underfoot, wiring that can’t support a modern appliance load, or a layout that can’t serve a family or rental tenant any longer.
What it costs in Crestline
A full gut-and-rebuild in Crestline typically starts around $35,000 and runs up to $65,000 when the work includes structural reinforcement, panel upgrades, and moving plumbing lines.
How we do it
We strip the room to framing, bring the structure up to current snow and seismic code, rerun electrical and plumbing, insulate to mountain standards, hang and finish drywall, then set cabinets, counters, appliances, and trim in sequence.

How long does a kitchen remodel take in Crestline?
Most Crestline kitchen remodels run six to ten weeks. Structural floor work, permit review with the county, and weather delays in winter months can push the schedule. We give you a written timeline before we start cutting, and we hold to it.
Will my Crestline kitchen remodel need fire-resistant materials?
If the work touches an exterior wall, a range hood vent, or any penetration through the building envelope, Cal Fire Chapter 7A requirements can apply. Fire-resistant exterior cladding like James Hardie fiber-cement siding often becomes part of the scope, and we plan for that from the first estimate so it isn’t a change order later. Call (833) 589-8273 for an exact quote.
Brands We Service in Crestline
We work across the leading prefab ADU manufacturers, including Boxabl, Plant Prefab, and Tuff Shed for accessory structures, and we specify James Hardie fiber-cement siding on exterior applications where fire resistance and long-term durability matter.

FAQs About ADU Company in Crestline
We schedule Crestline estimates within a week of your call in most cases. Because every Crestline lot has slope, tree, and access conditions that affect the quote, we walk the property in person rather than pricing from satellite images. Call (833) 589-8273 to book a time.
Yes. We pull all building permits through San Bernardino County and coordinate Cal Fire defensible-space and Chapter 7A compliance as part of the permit package. If a geotechnical report or retaining-wall engineering is required, we bring in the right licensed professionals and keep that work inside our contract.
That’s exactly how we prefer to work. Combining a main-house kitchen remodel with an ADU build on the same Crestline property means one permit coordination effort, one site mobilization, and one contractor accountable for both scopes. You avoid the scheduling gaps that come from splitting the work between two crews.
