Fast, Reliable General Contractor Across Rialto
If you’re searching for a General Contractor in Rialto, the first thing you should know is that most full remodels here run between $14,000 and $45,000, depending on the scope, and the biggest cost driver is what’s hiding under your slab. Most of Rialto’s housing stock is post-1950 tract construction on slab-on-grade with original cast-iron drain lines, which means a visual walkthrough alone won’t give you an honest price. We’re Mason Remodeling, and we’ve been scoping and pricing Rialto work long enough to know exactly where to look before we put a number in writing. Call (803) 680-2547 and we’ll walk your project room by room.
Why Mason Remodeling Is Rialto’s Preferred General Contractor Company
Rialto homeowners call us because we don’t quote off a clipboard and a guess. We scope the actual conditions: the age of the cast-iron under the slab, the insulation depth in the attic, the panel capacity at the main, and the permit path through the city. That changes the price, and you deserve to know it before demolition starts, not after. Every Mason Remodeling project gets a written price before any work begins. Not a ballpark, not a verbal estimate. A written line-item price. That’s the Threshold Standard, and it applies to every job we take in Rialto without exception.
We also send you exactly who is coming. Every crew member is background-checked, identity-verified, and in a clean marked uniform. You receive the technician’s name and photo before the visit, and they show a photo ID badge at your door when they arrive. If you’re home alone, or you’ve got kids napping in the back room, that matters. And if the work isn’t right within 365 days of completion, we make it right at no cost to you. That’s the 365-Day Done Right Promise, written into every contract.

General Contractor Services in Rialto
General Contractor Services in Rialto means one company accountable for the whole job: demo, rough-in, finish work, permits, and the city inspection sign-off. A homeowner in the Las Colinas or Sunflower Ridge area typically brings us in when a kitchen or bath has hit the end of its useful life, or when the floor plan no longer works for the family living in it. Kitchen remodels in Rialto run $14,000 to $45,000. Bathroom remodels run $9,000 to $28,000. Both ranges assume we’ve already inspected what’s under the slab, because that’s the line item that separates an honest price from a surprise change order.
Whole-Home Coordination
When a Rialto home needs work across multiple trades (framing, plumbing, electrical, tile, cabinetry), someone has to own the sequence and the inspection calendar. We do. We schedule the rough-in to pass before drywall, schedule the finish work after the city signs off, and keep the draw schedule tied to completed milestones rather than dates on paper.
Structural and MEP Scope
Load-bearing changes, panel upgrades, and drain-line reroutes are not finish work. In a slab-on-grade house, moving a kitchen sink across the room means breaking concrete and routing new ABS under the slab. We price that before demo. If it’s not in the written scope, you won’t see it as a surprise invoice.

Construction Company in Rialto
A Construction Company in Rialto that actually builds here has to understand what these houses are made of: post-1950 tract construction, slab foundations, cast-iron drains, and attics that were under-insulated by modern Title 24 standards. Home additions in Rialto run $45,000 to $130,000. ADU construction runs $90,000 to $220,000. Those are broad ranges because a 400-square-foot ADU with a kitchen and a separate meter is a different job than a bump-out off the back wall, and we scope both the same way: from the foundation up, with permits pulled and inspections passed.
Additions and ADUs
A room addition in Rialto means matching the existing slab elevation, tying the roofline cleanly, and upgrading the service panel if the load calculation demands it. We handle the architecture, the structural drawings, and the permit set. The price is written before we move dirt.
Garage Conversions
Garage conversions in Rialto run $30,000 to $80,000 and carry their own set of city requirements: insulation, egress, ventilation, and often a separate entry. We pull the permits, pass the inspections, and hand you the sign-off at final.
Trusted Brands We Service in Rialto
On a Rialto remodel, you’re not limited to whatever a subcontractor has in the back of the truck. We run specification-grade partnerships with KraftMaid and Wellborn cabinetry, Cambria, Silestone, and Caesarstone surfaces, and Kohler, Moen, and Toto fixtures. For hardscape and structural concrete work, we spec Sakrete mixes appropriate for the Inland Empire’s summer heat, which matters when you’re pouring a slab or setting fence posts in July. We don’t stock inventory in Rialto; we order direct and stage deliveries to your address, so lead times are real and quoted, not guessed. You pick the finish, we put it in writing, and the order goes on the draw schedule.
Common General Contractor Problems We See in Rialto Homes
- Underslab cast-iron failures. Most Rialto houses built before the mid-1970s have cast-iron drain lines under the slab. By now, they’re corroded, root-intruded, or cracked. We inspect before we quote; a wall-out remodel can turn into a slab-access job, and that changes the number.
- Permit stalls on structural or MEP work. Rialto requires permits and inspection sign-off on structural, plumbing, and electrical work. If a previous contractor skipped the permit, the current project inherits the correction. We pull permits ourselves and schedule inspections in sequence so the draw schedule stays on track.
- Vague allowance language. A contract that says “allowance for cabinets” doesn’t tell you what you’re buying. When you pick KraftMaid or Cambria later, the scope of work no longer matches the signed price. We spec the actual product, the actual finish, and the actual quantity before the contract is signed.
- Insulation and Title 24 compliance on additions. Older Rialto homes were built with minimal attic insulation and single-pane windows. When you add square footage, the new space has to meet current energy code. We calculate Title 24 compliance as part of the scope, not as a post-inspection surprise.

AfterPricing for General Contractor in Rialto, CA
Here are honest, market-calibrated ranges for the work Rialto homeowners ask us about most. These numbers assume a typical post-1950 slab-on-grade home, normal site access, and permits pulled by us. If we find underslab repairs, panel upgrades, or structural work during the inspection, we’ll write it into the price before you sign, not after we’ve opened the wall.

FAQs About General Contractor in Rialto
A kitchen or bath remodel in Rialto typically requires building, plumbing, and electrical permits, and structural permits if you’re removing or altering load-bearing walls. Mechanical permits apply if you’re relocating HVAC. We pull every permit, schedule the inspections in the city’s required sequence, and the project isn’t considered complete until the final sign-off is recorded. Call (803) 680-2547 and we’ll tell you exactly which permits your specific project will trigger.
We price it by inspecting the underslab plumbing before we write the contract. On a 1960s tract home near Rialto Avenue and Willow, our crew opened a galley kitchen for a full remodel and found the cast-iron drain under the slab had root intrusion at the wye, so we had to break out a 4-foot section of slab, reroute to ABS, and pour back before cabinet set. We wrote the underslab reroute as a change order before demolition, kept the KraftMaid cabinet order and Cambria counter template on the draw schedule, and finished the punch list with the city inspector’s sign-off on the rough-in and final. That’s how it should go: the hidden condition becomes a written line item, not a surprise.
A kitchen remodel in Rialto typically runs 6 to 10 weeks from demo to final inspection; a bathroom runs 3 to 5 weeks. The calendar is driven by the city’s inspection sequence: rough-in passes before drywall, final passes before you take the keys back. We give you a written schedule tied to milestones, not dates pulled from the air, and we update it as inspections pass. Call (803) 680-2547 for a timeline specific to your project.
Three things change a Rialto remodel price: underslab cast-iron replacement, structural corrections the city requires, and finish selections that were left as vague allowances. We eliminate all three by inspecting the slab and drains before quoting, pulling permits and passing the rough-in before the walls close, and spec’ing your actual cabinets, counters, and fixtures before the contract is signed. If you authorize a change, it’s a signed change order with a set price. Nothing else moves the number. Call (803) 680-2547 and we’ll show you what a written, fixed-scope price looks like.
Yes. ADU construction in Rialto runs $90,000 to $220,000, and home additions run $45,000 to $130,000. Both require architectural drawings, structural engineering, Title 24 energy calculations, and full permit and inspection sign-off. We handle every part of it from the slab up, and the price is written before we break ground. Call (803) 680-2547 for a free estimate on your Rialto addition or ADU.
