Fast, Reliable General Contractor Across Crestline
Hiring a General Contractor in Crestline means finding someone who understands what 4,500 to 5,000 feet of elevation does to a building. Snow load, freeze-thaw cycling, steep slopes, and wildfire exposure shape every decision here, from footing depth to roof framing to the siding you choose. Timberline Contractors has spent years working on Crestline’s older mountain cabins, A-frames, and hillside homes, and we know what the local building department will flag before you spend a dollar. Call (866) 253-5808 for a free estimate on your remodel, addition, or full exterior upgrade.
Why Timberline Contractors Is Crestline’s Preferred General Contractor Company
Crestline homeowners call us because we quote the job the way the mountain actually demands, not the way a valley contractor would price it from a flat warehouse in San Bernardino. That difference shows up in the first conversation: we ask about your foundation type, your roof pitch, your snow-load history, and whether the county has record of every addition on the property. Skipping those questions produces a bid that falls apart at inspection. Nelson Fung built Timberline Contractors around this exact discipline, and his approach carries through every estimate, permit packet, and change order.
Our Crestline customers consistently point to two things in reviews: we show up when we say we will, and the final invoice matches the written line-item quote. That matters in a mountain market where weather windows close fast and a missed rough-in can push a project back six weeks. We schedule Crestline work around the snow season with realistic sequencing, and our crews know the roads off Highway 18 well enough to plan material deliveries around grade and switchback constraints.
Local knowledge here is not a marketing line. It is knowing that a 1970s cabin on pier-and-post footings may need a lateral retrofit before you add square footage. It is knowing that Lake Gregory-adjacent lots get heavier wet snow than the higher ridgelines, and that drainage across a hillside lot has to be engineered before any hardscape goes in. That is the level of detail Crestline homeowners should expect from a General Contractor in Crestline.
Styles & brands we work with







Construction Company in Crestline
As a Construction Company in Crestline, Timberline Contractors handles the full build sequence: demolition, structural correction, framing, rough-in, finish work, and final inspection. In most Crestline homes, the first step is not swinging a hammer. It is understanding what is already there and whether it can support what you want to add. A typical room addition in Crestline runs $45,000 to $130,000 depending on slope conditions, foundation work, and finish level, while a garage conversion runs $30,000 to $80,000 and an ADU construction project runs $90,000 to $220,000, though ADU pricing moves significantly based on whether you choose a traditional stick-built unit or a prefab route through partners like Dvele repair in Crestline, Abodu, or Boxabl.
Slope and Foundation Corrections
Many Crestline lots pitch at 15 to 30 percent or more, which means any addition starts with geotechnical or structural assessment of what holds the existing building up. Pier-and-post systems from the 1960s and 1970s were rarely designed for the snow loads current code requires. A compliant quote includes footing enlargement, post replacement, or lateral bracing where the inspector will require it, not just where it is convenient.
Permit-Ready Scope and As-Built Legalization
Older Crestline cabins frequently carry additions that were never permitted. Before new scope can be approved, the county wants to see the existing conditions documented and corrected to code. We build that as-built legalization step into the estimate from day one. It adds cost, but it is the only path to a final sign-off that carries any weight with your insurer.
Remodeling Contractor in Crestline
As a Remodeling Contractor in Crestline, we do not treat your mountain home like a suburban track house with a steeper driveway. Remodel work here means working inside homes built for a different era, with outdated electrical panels, single-pane windows, and framing that has settled over decades of freeze-thaw cycling. A full kitchen remodel in Crestline typically runs $14,000 to $45,000, while a bathroom remodel runs $9,000 to $28,000 and a roof replacement runs $8,000 to $20,000. What drives those numbers: load-bearing corrections, insulation upgrades, snow-rated roof assemblies, and the cost of getting materials up a mountain road.
Interior Remodel on Mountain Footprints
Crestline homes are often small-footprint cabins and A-frames where opening a wall means touching structure. We sequence kitchen and bath remodels carefully: confirm the bearing conditions first, order custom cabinetry early from partners like KraftMaid or Wellborn, and time countertop templating from Cambria or Silestone around the rough-in window. The result is a remodel that feels intentional, not wedged in.
Exterior Envelope and Snow-Load Retrofits
Remodeling in Crestline is not only cosmetic. A roof that has carried wet snow for twenty years may need new sheathing, stronger rafters, or a full replacement to GAF or CertainTeed shingles rated for the local snow load. Our exterior remodels connect the roof, siding, and drainage into one scope so water does not find its way behind new interior finishes. That is the difference between a remodel that lasts and one that fails the first hard winter.
Trusted Brands We Service in Crestline
We bring a curated catalog of more than 50 brand partners to Crestline, which means you are not stuck choosing from whatever a single showroom keeps in stock. For hardscape and paver work on hillside retaining walls, fire pits, or driveways, we install Unilock, Techo-Bloc, and Cambridge Pavers systems that hold up to frost and slope drainage. Roofing runs through GAF, CertainTeed, Owens Corning, and IKO, so you get six manufacturer options instead of one. On kitchen and bath finish work, Cambria quartz, Silestone, Kohler, and Toto are standard options, not upgrades we ration. We stock common parts locally so Crestline customers do not wait for a valley run when a trim piece is missing.

AfterCommon General Contractor Problems We See in Crestline Homes
- Undersized pier-and-post foundations showing snow-load deflection. We see sag in deck framing and floor joists on nearly every hillside home built before 1990, and a remodel that ignores it is building on borrowed time.
- Unpermitted additions from decades past that block any new permit. The county will not approve new scope on a property with illegal square footage, so we fold as-built legalization into the same project schedule.
- Roof assemblies without ice-dam or ember-resistant detailing, which either leak after the first hard freeze or get flagged during a fire-hardening review. Crestline’s wildfire zone requires Class A-rated assemblies and specific vent detailing that flatland roofers often skip.
- Drainage and erosion failures on sloped lots where a downspout dumps against a hillside foundation or a walkway channels water under the house. We correct grade and install proper drainage before finish work covers the evidence.

FAQs About General Contractor in Crestline
Yes. Crestline sits at roughly 4,500 to 5,000 feet, and the county requires roof and deck framing designed for the local snow-load zone, which is significantly higher than the valley below. A structural engineer stamps the calcs, and the inspector checks them. Call (866) 253-5808 if your deck is sagging or you are planning an addition, and we will tell you what the engineering step will cost before you commit.
Yes, and we do this routinely. We start with an as-built documentation step, bring the existing structure up to current code where required, and then fold your new remodel scope into the same permit package. That sequence is the only way to get a legal sign-off on a property with prior unpermitted work.
Documented, to-code work gives your carrier the paper trail they need to write or renew a policy without excluding the mountain-specific risks. Our inspection sign-off packets on a recent hillside A-frame remodel off Lake Gregory became exactly what the homeowner’s carrier wanted at renewal. The alternative is a claim that gets challenged because the work was never permitted.
A compliant Crestline quote includes engineering for snow load and slope stability, footing and foundation corrections, as-built legalization on unpermitted additions, ice-dam and ember-resistant roof detailing, and erosion control on sloped lots. A cheap quote omits those line items, then hits you with change orders at inspection. Ours lists them from the first estimate, which is free, at (866) 253-5808.
Yes. We build new ADUs, additions, and full exterior envelope projects alongside remodels of mid-century A-frames and 1960s-1980s cabins. Working on older mountain homes means we sequence structural correction before finish work, and we carry that discipline into new construction where snow load and fire hardening apply from the first framing inspection.
