Why Mason Remodeling Is Running Springs’s Preferred General Contractor Company

Running Springs homeowners keep calling us back because we write the price before the first tool comes off the truck, and we put a name and a face to every crew member who walks up the driveway. Isaac Pruett leads our general contracting work, and he insists on the same thing on every job: a written scope, a written price, and a written guarantee with a 365-day completion date on it. That matters more on a steep hillside lot than anywhere else, because the unknowns are real and the fix has to be handled without drama.
We work all over Running Springs, from Smiley Park up toward the Highway 330 corridor and across the ridgeline roads where driveway access gets tight. Our crews know what county inspection expects on structural changes to older mountain cabins, and we pull permits on anything load-bearing. Homeowners here tell us the same thing: once they see the technician’s name and photo before the visit and the ID badge at the door, the whole conversation changes. That’s the Threshold Standard, and it applies to every Mason Remodeling job, no exceptions.
The General Contractor team at Mason Remodeling has been doing this since 2004 as part of the Threshold Group family. We’re not new to mountain work, and we’re not going to price your Running Springs project like a flatland build and then surprise you later.
Styles & brands we work with







Remodeling Contractor in Running Springs
A remodeling contractor in Running Springs handles the full sequence: demolition, rough framing, structural repair, plumbing and electrical rough-in, drywall, finishes, and the final walk-through with the inspector. The slopes here change the framing plan before anything else. Most of the housing stock on the mountain dates back decades, and once walls open, what looked like a cosmetic refresh often turns into structural work on rim joists, subflooring, and load-bearing beams. That’s normal here. It just needs to be priced honestly before you’re halfway through.
A kitchen remodel in Running Springs typically runs $14,000 – $45,000 depending on cabinet grade, whether you’re moving plumbing, and how much structural repair the existing framing needs. A bathroom remodel runs $9,000 – $28,000, with the lower end covering a cosmetic refresh on a small cabin bath and the upper end covering a full gut with a custom walk-in shower and snow-load-rated framing changes.
Kitchen Work on a Hillside Cabin
Older Running Springs kitchens were often built with whatever framing was available at the time, and that means walls that are not square, floors that have settled with the slope, and plumbing runs that don’t match current code. We plan for that. Cabinet installation here runs $4,000 – $13,000, and countertop work $2,000 – $6,500, with Cambria and Silestone among the surfaces homeowners ask for most.
Bath Work in Older Mountain Homes
A tub-to-shower conversion in a Running Springs cabin often triggers more than just a pan replacement. Water has usually been sitting against the subfloor for years. We scope that before we quote, so the number we hand you on paper is the number you can plan around, not a starting point.
Licensed General Contractor in Running Springs

A licensed general contractor in Running Springs takes responsibility for the permit set, the structural engineering, the scheduling of subcontractors, and the final inspection sign-off. On a mountain lot, that license matters more, because the county wants to see load calculations on anything that changes the way snow sits on, or water runs under, your home. We handle that end-to-end, and we do it without asking you to be the go-between.
For a home addition in Running Springs, plan on $45,000 – $130,000. The wide range reflects the actual cost drivers here: hillside grading, retaining walls, foundation depth on sloped lots, and whether the addition ties into existing cabin framing or stands on its own. A garage conversion runs $30,000 – $80,000, and the same grading and snow-load rules apply.
Permits, Engineering, and Inspections
We pull permits on decks, additions, and any structural change to an older cabin. Skipping the permit on a load-bearing change is the fastest way to fail sign-off and end up tearing finished work back out. Our team handles the engineering and the county inspection, so the punch list is closed before we call the job done.
Written Scope and Written Price
Every project gets a written price before work begins. That includes a line-item scope, the permit path, and the exclusions stated plainly. If something changes once the walls are open, we write a change order and you approve it before we proceed. No verbal estimates that grow on the final bill.
Trusted Brands We Service in Running Springs
We install and service cabinetry from KraftMaid and Wellborn, surfaces from Cambria and Silestone, and fixtures from Kohler and Moen. Because we’re running jobs all over the Running Springs area, we can often source parts faster than a homeowner ordering solo. A written line-item quote names the brands and the allowances up front, so you’re not approving a mystery cabinet line at the end of the job. We also work around prefab and panelized build options where they fit a mountain lot’s access constraints, names like Abodu and Mighty Buildings come up on some hillside ADU conversations.

AfterCommon General Contractor Problems We See in Running Springs Homes
- Hidden dry rot at deck ledgers and rim joists. Older mountain cabins hold water against the frame in ways flatland houses don’t. Once a wall or a deck is opened, what started as a cosmetic refresh often becomes a structural repair.
- Slope-driven grading and drainage surprises. Running Springs lots tilt, and water follows the grade. A plan that doesn’t include drainage, retaining, or re-sloping will fail long before the finishes do.
- Snow-load framing that was never rated for current code. Roofs and beams on 40 and 50 year old cabins often need a snow-load upgrade before the county will sign off on an addition or a second-story change.
- Access for deliveries and crews on ridgeline roads. Tight driveways and switchbacks on Highway 18 and the smaller ridge roads change how materials get staged. We plan for that, so the dumpster and the lumber don’t block your only way out.

FAQs About General Contractor in Running Springs
Yes, you need a permit for any structural, electrical, or plumbing change, and in Running Springs the county specifically reviews load calculations on changes to older cabin framing. We pull the permits and handle the inspection sign-off so the finished work stays legal and insurable. Call (803) 680-2547 if you want us to look at your cabin and tell you exactly what the permit path looks like.
We write a fixed base scope with named allowances for the known finishes, plus a written change-order process for what’s discovered after demo. That way you get a real number, not a guess. If we open a wall and find dry rot or a failing subfloor, you approve the added line item before we continue, and the price is never a verbal promise that grows on the final bill. Call (803) 680-2547 for a written estimate.
A snow-load-rated beam typically adds $1,500 – $4,000 in material and engineering on a mid-size remodel, depending on span and what it’s carrying. On a hillside cabin, the county often requires that upgrade before signing off on an addition or a load-bearing wall removal, so we price it in from the start rather than discovering it at inspection. Call (803) 680-2547 and we’ll tell you exactly what your specific roof and slope require.
A cosmetic bathroom refresh on a Running Springs cabin can run 2 – 3 weeks once demo starts. A full kitchen with structural repair, permit inspections, and cabinet installation usually runs 6 – 10 weeks. Mountain weather, inspection scheduling, and what we find inside the walls can shift that window, and we’ll update the calendar in writing as the job progresses. Call (803) 680-2547 for a schedule tied to your actual project scope.
The single biggest price change in Running Springs is hidden dry rot behind the walls and under the floor, which the original quote could not see. The second is unplanned grading or drainage work once the slope is exposed. Both are handled through a written change order you approve before we spend another dollar. Call (803) 680-2547 if you want a contractor who writes that process into the agreement from day one.
