Fast, Reliable General Contractor Across Clayton
Most Clayton homeowners call a general contractor because something in their house no longer works the way it should, or they’re ready to stop living around an outdated kitchen or bath. What they actually need first is a straight answer on scope, permits, and price. That’s what Mason Remodeling delivers. We coordinate every trade, pull the permits Clayton requires, and put the full project cost in writing before the first tool leaves the truck. If you’re planning work in Clayton and want a real number instead of a vague estimate, call (803) 680-2547 for a free, no-pressure site visit.
Why Mason Remodeling Is Clayton’s Preferred General Contractor Company
Clayton homeowners don’t hand their house keys to just anyone. The hillside lots, older framing, and narrow streets off Clayton Road and Marsh Creek Road reward a contractor who has actually done this kind of work here. Our General Contractor team has managed remodels and additions across Clayton neighborhoods including the Oakhurst Country Club area, the flats near downtown along Main Street, and the winding residential streets above Marsh Creek. We understand what design review and hillside grading mean for your schedule, because we’ve sat in those permit queues.
Every Mason Remodeling crew member is background-checked and identity-verified before setting foot on your property. You receive the name and photo of each technician before the visit, and they arrive in a clean marked uniform with a photo ID badge at the door. That’s the Threshold Standard, and it applies to every job in Clayton without exception. We don’t treat it as an upgrade. It’s the floor.
We also answer the phone. Not a call tree, not a voicemail box. A live person picks up 24 hours a day, seven days a week. When you’re mid-remodel and a question comes up at 7 a.m. on a Saturday, you reach a human who knows your project.
Styles & brands we work with
Licensed General Contractor in Clayton
A Licensed General Contractor in Clayton is the single point of responsibility for your remodel, addition, or whole-home project. Instead of you juggling separate plumbers, electricians, drywallers, and inspectors, one licensed firm coordinates every trade, holds the permit, and answers for the finished result. You need this kind of oversight for nearly any Clayton project that touches structure, plumbing, electrical, or load-bearing walls – which most kitchen and bath remodels do. A Clayton kitchen remodel typically runs $14,000 to $45,000, while a bathroom remodel lands between $9,000 and $28,000 depending on size, fixtures, and what’s hiding behind the walls.
Permits and inspections handled start to finish
Clayton pulls building permits through the city, not the county, and hillside lots often trigger additional design review or grading checks. We prepare the plans, submit for review, schedule inspections, and keep the job moving when the city asks for revisions. You never chase a permit or decode an inspector’s correction note. You also see the permit status on every draw schedule update.
What you know before work starts
You get a written scope of work, a line-by-line price, and a draw schedule before you sign anything. Allowances for cabinets, counters, and fixtures are spelled out in dollar amounts, not left vague. If a subfloor or beam issue surfaces during demo, the change order process is written into the contract, not invented mid-job in a hallway conversation.
Residential General Contractor in Clayton
A Residential General Contractor in Clayton handles the projects that make your house function better for the way you actually live – kitchen remodels, bath remodels, room additions, whole-home renovations, and accessory dwelling units. Unlike a commercial contractor, a residential GC works around your family’s daily rhythm, manages dust and debris on a tight Clayton lot, and coordinates neighbors’ access when staging spills onto the street. Home additions in Clayton range from $45,000 to $130,000 depending on square footage, foundation work, and finish level. ADU construction runs $90,000 to $220,000, which includes design, permits, utilities, and finishes.
Structural changes and load-bearing walls
Clayton’s housing stock includes a lot of 1960s and 1970s ranch and split-level homes where kitchens and baths were framed against load-bearing walls. Moving a wall or relocating a sink often means installing a properly sized beam and new rough-in. We engineer that work, pull the permits, and frame it to pass inspection the first time. You don’t guess, and you don’t get a surprise structural line item on the final invoice.
Project management with one contact
One project manager runs your Clayton job from demo to final walkthrough. You get a weekly status update, a clear schedule, and a direct phone line to the person accountable for your project. If a question comes up about cabinet delivery or tile layout, you call one number and get an answer the same day.
Trusted Brands We Service in Clayton
We install and service materials from brands Clayton homeowners can actually visit in local showrooms and compare side by side. For kitchen work, we specify KraftMaid and Wellborn cabinetry with Cambria, Silestone, or Caesarstone surfaces. Bathroom projects draw on Kohler, Moen, Toto, and Grohe fixtures. When a Clayton job calls for exterior work, we recommend GAF, CertainTeed, or Owens Corning roofing products and Belgard, Unilock, or Techo-Bloc hardscaping materials. Because several Clayton suppliers along the 680 corridor stock these lines locally, lead times stay shorter than ordering from out-of-state warehouses. We also stay current on prefab and panelized options from Cover and Dvele for Clayton homeowners evaluating faster ADU builds on tight lots.

AfterCommon General Contractor Problems We See in Clayton Homes
- Photo-only bids that miss what’s actually in the walls. A contractor quotes from your emailed pictures, then finds rotted subfloor, a bearing wall, or outdated wiring once demo starts. The price jumps because nobody walked the job first. We don’t bid without a site visit.
- Hillside permit rejections that stall projects for months. Clayton’s design review and grading requirements catch out contractors who treat this hillside city like a flat-lot suburb. We submit complete plans the first time because we know what the city reviewer looks for.
- Vague allowances that blow the budget at the cabinet store. A contract says “allowance included” without a dollar figure. Then you pick KraftMaid boxes and a Cambria top, and the change order arrives. Our allowances are written in real dollar amounts before you sign.
- Scattered crews with no single point of contact. Three different subs show up, none of them knowing the full scope. You become the unpaid project manager. One Mason Remodeling PM runs the whole job and answers to you directly.

FAQs About General Contractor in Clayton
Yes, almost always. Any Clayton project that moves plumbing, alters electrical, removes or cuts into a wall, or changes the home’s structural framing requires a city building permit through the city of Clayton. Some hillside lots also need design review or grading sign-off before the permit is issued. Mason Remodeling handles all permit applications and inspections as part of the written scope of work. Call (803) 680-2547 to find out exactly which permits your project will need.
A standard Clayton kitchen remodel runs 6 to 12 weeks from contract through final inspection, while a bathroom remodel typically takes 3 to 6 weeks. Home additions and ADUs run 4 to 9 months depending on scope and hillside permit review. Your project manager gives you a realistic calendar before you sign, with milestone dates for demo, rough-in, inspection, and finish. Call (803) 680-2547 and we’ll map out a timeline that fits your project.
The honest answer: hidden conditions behind walls, or your own selection changes. Rotted subfloor, a load-bearing wall that needs a beam, or outdated wiring discovered during demo are legitimate change-order items. We build a contingency line and a written change-order process into every Clayton contract so you never pay for something that wasn’t disclosed and approved in writing first. For a quote with clear change-order terms, call (803) 680-2547.
Yes. We remove load-bearing walls, size and install beams, and coordinate the engineering and permit work required in Clayton’s hillside and older homes. This is exactly the kind of work that separates a licensed general contractor from a handyman, and it’s built into our kitchen and whole-home remodel scopes. Call (803) 680-2547 and we’ll walk your home to see what’s load-bearing and what’s not.
You walk the finished project with your project manager and note anything that needs attention: a cabinet door that sits slightly off, a paint touch-up, a grout line that needs cleaning. We document every item, schedule the fixes, and complete them before we consider the job done. Then the 365-Day Done Right Promise kicks in: if anything isn’t right within a year of completion, we come back and make it right at no cost to you. Call (803) 680-2547 to schedule your free estimate.
