Fast, Reliable General Contractor Across Piedmont
General contractor work in Piedmont, CA is different from the flatlands. A kitchen remodel that would be straightforward in Emeryville often turns into structural work here because the pre-1940 houses sit on steep, slab-on-grade or raised foundations with decades of hidden rot underneath. Mason Remodeling has been handling exactly this since 2004, and the single most important thing we tell Piedmont homeowners is this: get the price in writing before demolition starts. We deliver a written line-item quote on every project, every time, before a single tool is unpacked. Call (803) 680-2547 to schedule a free estimate for your General Contractor project.
Why Mason Remodeling Is Piedmont’s Preferred General Contractor Company
Piedmont homeowners call us because we understand what’s behind their walls. The housing stock here runs old – much of it built between 1900 and 1940 – and that means knob-and-tube wiring, termite-compromised subfloors, and framing that no longer meets current seismic code. Our crews have worked in Crocker Highlands, Piedmont Avenue, and the streets off Highland and Wildwood. We don’t guess; we scope. Every project gets a written price, and every crew member who comes to your door arrives in a clean uniform with a photo ID badge, introduced by name and photo before the visit. That’s the Threshold Standard, a named verification process, and it’s how we’ve earned trust in Piedmont since our founding as part of the Threshold Group family of home-service companies. A live person answers our phone 24 hours a day, seven days a week – no call trees, no voicemail loops.
Styles & brands we work with
Construction Company in Piedmont
A Construction Company in Piedmont does the heavy lifting: demolishing load-bearing walls, raising headers, replacing subfloors, and framing additions that meet the city’s own building department requirements. When a Piedmont homeowner calls us for this kind of work, they’re usually planning a kitchen or whole-home project where the existing structure needs real engineering before finishes go in. A typical home addition in Piedmont runs $45,000 – $130,000. An ADU – increasingly common as Piedmont homeowners try to add rental value without leaving their neighborhood – runs $90,000 – $220,000. The single biggest cost driver here isn’t finishes. It’s what the city’s plan-check reviewer flags after we open the walls.
Structural and Permit Work
Most pre-1940 Piedmont homes need a structural letter from a licensed engineer before any load-bearing change gets approved. That letter, plus the city’s plan-check sign-off, typically adds two to four weeks to the calendar. We pull every permit, coordinate the inspections, and make sure the rework passes the first time.
Foundation and Subfloor Repair
In Piedmont’s hillside lots, a small kitchen remodel regularly exposes rot where the mudsill meets the subfloor. It’s not an upsell. It’s a code requirement. We write the change order, price it in writing before proceeding, and keep the project moving on a clear draw schedule.
Remodeling Contractor in Piedmont
A Remodeling Contractor in Piedmont handles the visible transformation: new cabinetry, countertops, flooring, tile, and fixtures installed inside an older home that wasn’t plumb or square to begin with. The finishes matter, but the prep work matters more. A kitchen remodel in Piedmont runs $14,000 – $45,000. A smaller kitchen remodel runs $9,000 – $20,000. A bathroom remodel runs $9,000 – $28,000, and a small bath runs $5,000 – $12,000. Window replacement runs $4,500 – $15,000. Those are the honest local ranges, and they reflect what it takes to get level countertops and square cabinet runs inside walls that haven’t moved in ninety years.
Kitchen and Bath Interior Work
We install specification-grade cabinetry from KraftMaid and Wellborn, and surfaces from Cambria, Silestone, and Caesarstone. In a 1928 bungalow, that means shimming studs, sistering joists, and floating floors before the first base cabinet gets set. We price that prep work up front, not after demo.
Whole-Home and Addition Scope
Piedmont homeowners doing whole-home work need a general contractor who can sequence subs without letting the project stall at inspection. We coordinate plumbing, electrical, structural, and finish trades under one written scope, with a written guarantee covering every job for 365 days from the completion date.
Trusted Brands We Service in Piedmont
We spec materials that hold up in Piedmont’s cool, damp winters and dry summers, including solid-wood cabinetry and quartz surfaces that don’t warp or stain when the marine layer rolls in off the Bay. Our vetted product lines include Cambria and Caesarstone for countertops, Wellborn for cabinet boxes and doors, plus ABODU, Cover, and Dvele for pre-engineered ADU and accessory dwelling unit shells. We maintain supplier relationships that let us get replacement parts and hardware to Piedmont jobsites quickly when something fails mid-project, and our 365-Day Done Right Promise backs every completed installation.
Common General Contractor Problems We See in Piedmont Homes
- Hidden subfloor rot under old kitchens and baths. We find it on roughly half of the pre-1940 Piedmont jobs we scope. The fix is structural repair before finishes, and it’s priced in writing when we find it.
- Knob-and-tube wiring still live behind walls. Many Piedmont homes never had their original electrical fully replaced. If we open a wall and find active knob-and-tube, we stop work, bring in the electrical permit, and price the upgrade before proceeding.
- Design review delays on visible exterior work. Piedmont’s own building department reviews exterior changes and additions, and that review can stretch a timeline by two to four weeks. A good contractor builds that into the schedule before you ever sign.
- Scope creep from verbal allowances. Homeowners who accept “we’ll figure it out when we open it up” end up with change orders that weren’t priced. We write allowances, walk you through the local failure modes, and price every change in writing before work continues.

FAQs About General Contractor in Piedmont
A typical kitchen remodel in Piedmont takes 8 to 14 weeks once permits are approved, and two to four of those weeks are often spent waiting on the city’s plan-check and design review when load-bearing work is involved. The demo, structural repair, rough-in, and finish phases can move quickly once inspections pass, but the pre-construction review on an older home is the part nobody can speed up. Call (803) 680-2547 to get a realistic calendar for your specific house.
Yes, in most cases. Piedmont’s building department requires permits whenever you move plumbing, change a shower valve, touch structural framing, or alter the rough-in. A simple fixture change in place may not need one, but the moment you open a wall and find rot or outdated wiring, the permit becomes unavoidable. We pull all required permits and manage inspections for you. Call (803) 680-2547 to have us check your scope before you start.
A kitchen remodel in Piedmont runs $14,000 – $45,000. A bathroom remodel runs $9,000 – $28,000. A home addition runs $45,000 – $130,000. Those ranges reflect local labor, permit fees, and the structural surprises that come with pre-1940 hillside homes. Every project gets a written line-item quote before work begins, so you’ll know your number before you commit. Call (803) 680-2547 for a free estimate.
A change order is a written document that amends your original scope and price. When we open a wall in a Piedmont home and find termite damage or a rough-in that no longer meets code, we stop, write the change order with a specific price, and get your written approval before proceeding. You never get a surprise invoice at the end. That’s the only way we work. Call (803) 680-2547 to discuss your project scope.
Yes. Piedmont has its own design review process for visible exterior changes, and we prepare the drawings, submittal package, and response letters the city requires. We also build the design-review timeline into your schedule so the finish date doesn’t slip without you knowing why. Call (803) 680-2547 to have us walk you through what your project will need.
