Fast, Reliable General Contractor Across Colton

You need a General Contractor in Colton who can look at a job, tell you what it will actually cost, and then do the work without drama. That’s what we do. Mason Remodeling has been doing this since 2004, and our crews know Colton’s streets, its older housing stock, and the San Bernardino County permit process that applies to almost every remodel here. We give you a written price before any work starts. Not a verbal estimate that drifts upward. A written price. Call us at (803) 680-2547 and we’ll walk you through exactly what your project involves, what it costs, and what’s guaranteed.

Why Mason Remodeling Is Colton’s Preferred General Contractor Company

Colton homeowners call us because we’re plain about how a job will go. We show up in clean marked uniforms, with photo ID badges, and we send you the name and photo of every crew member before they reach your door. That’s the Threshold Standard, and it’s not optional on any job we run. For a homeowner who’s often home alone, or a parent with young kids, or an older adult deciding whether to open the door, that matters more than a glossy brochure.

Our reputation in Colton comes from doing what we said we’d do. Isaac Pruett, who leads Mason Remodeling, built the company on a simple rule: a written price before a single tool is unpacked. No surprise invoices. No scope creep that shows up on the final bill without anyone telling you first. And every completed project carries a written guarantee. If something isn’t right within 365 days of completion, we make it right at no cost to you.

We also know Colton’s permit realities. Most work here goes through San Bernardino County, not a big-city building department with a streamlined online portal. Review timelines move at the county’s pace. Older parcels around the historic downtown core often have additions or converted garages that were never permitted when they were built. That changes how a job gets scoped, and we’ll tell you that on the first call, not after the inspector flags it.

Remodeling Contractor in Colton

A Remodeling Contractor in Colton handles what most people think of when they say “remodel”: kitchens, baths, flooring, walls, and the structural work that sits behind them. The first step is always the same. We check the permit history on your parcel, verify what’s original and what was added later, and write a scope of work that accounts for what we can see and what we reasonably expect to find once walls are opened. In Colton, that second part matters a lot.

Kitchen and Bath Scope Work

Kitchen remodels in Colton typically run $14,000 to $45,000. Bathroom remodels run $9,000 to $28,000. The range depends on whether you’re moving plumbing, replacing a tub with a walk-in shower, opening a wall, or working with mid-century framing that doesn’t match modern opening sizes. We put every line item in writing before work starts.

Older Colton Housing Stock

Colton has a lot of homes built between the 1940s and 1970s. That means cast-iron drain lines, undersized subfloors, and occasionally knob-and-tube wiring hiding in the ceiling. When a homeowner calls us about a “simple” bathroom swap, we plan for what we’re likely to find. If we don’t find it, great. If we do, the written scope already tells you what that correction costs. It’s why we never price an older Colton home the same way we’d price a new build.

Licensed General Contractor in Colton

A Licensed General Contractor in Colton handles what a Remodeling Contractor doesn’t: the work that requires permits, engineering, inspections, and a timeline measured in weeks or months, not days. Room additions, garage conversions, ADUs, and whole-home remodels all fall here. In Colton, these projects pull permits through San Bernardino County, and the review time varies. We handle the permit package, the plans, the inspections, and the county’s corrections. You get a single point of contact the whole way through.

Garage Conversions and ADUs

Garage conversions in Colton typically run $30,000 to $80,000. Full ADU construction runs $90,000 to $220,000. Those numbers assume the existing structure can be brought to code. On Colton’s older parcels, that’s not always true. An attached garage that was converted informally in the 1980s may have unpermitted electrical, missing vents, or slab issues that only show up when the inspector looks. We verify all of that against county records before we give you a number.

Home Additions

Home additions in Colton run $45,000 to $130,000. The single biggest cost driver is the foundation and structural tie-in. Colton sits on varied soil, and depending on the neighborhood, we may need different footing depths or shear wall details. We don’t guess at that. We have it engineered. The written price you get reflects the engineer’s scope, not a rule of thumb.

Trusted Brands We Service in Colton

We’re direct partners with vetted, professional-grade product lines, so Colton homeowners get access to the same materials custom builders specify. For cabinetry, we work with KraftMaid and Wellborn. For countertops and surfaces, Cambria, Silestone, and Caesarstone. For fixtures, Kohler, Moen, Toto, and Grohe. If you’re planning an ADU and want factory-precision components, we can also work with Mighty Buildings or Dvele on specific panelized systems. Because we order and coordinate these materials ourselves, Colton projects don’t stall waiting on a homeowner to chase down a vanity top or a shower valve.

Common General Contractor Problems We See in Colton Homes

  • Unpermitted conversions. Colton has generations of garage conversions and patio enclosures that were never permitted. When a new remodel triggers an inspection, the inspector looks at the whole assembly. If the old work isn’t up to code, it becomes part of the correction scope. We check county permit history before pricing anything.
  • Knob-and-tube and undersized subfloors. Many Colton homes built before 1950 still have wiring or floor systems that don’t meet current standards. The first day of demo is not when you want to discover that. We verify what’s likely to be in the walls as part of the scope of work, so it’s priced or visibly excluded from the start.
  • Missing or failed plumbing vents. Older Colton bathrooms often have drain lines that were patched rather than replaced. We saw this on a hall bath in the Reche Canyon area. When we opened the ceiling for the rough-in, a prior patch-job drain and a missing vent told us the plumbing wasn’t to current code. We added a change order for the drain line before inspection sign-off, rebuilt the bath with a Kohler toilet and Moen fixtures, used Cambria for the vanity top and a Silestone slab on the kitchen pass-through, and passed the county inspections on the first walk.
  • No written draw schedule. Colton’s job pacing is tighter than some neighboring cities, and without a written draw schedule and allowances, the crew ends up buying materials out of pocket and the client signs change orders mid-job instead of at planned milestones. That’s a recipe for friction. Our draw schedule is written into the contract before work begins.
