Fast, Reliable General Contractor Across Colton
If you’re planning a kitchen remodel, room addition, or full-home renovation in Colton, the biggest variable isn’t the tile you pick. It’s what’s hiding inside the walls. Colton’s housing stock runs heavy to post-WWII tract homes and mid-century ranches, and a lot of them still have original aluminum wiring, cast-iron underslab drains, and framing that was never meant to meet California’s current seismic code. The permitting process won’t let you ignore any of it. That’s where we come in. Polaris Contractors is a full-scope general contractor serving Colton and the surrounding Inland Valley, and we handle every phase of the work under one contract, from the first pre-construction inspection to final sign-off. Call (855) 473-6535 for a free estimate.
Why Polaris Contractors Is Colton’s Preferred General Contractor Company
Colton homeowners consistently tell us the same thing: they tried assembling a kitchen remodel with three different subs and it turned into a scheduling nightmare. We solve that problem by being the single accountable team from start to finish. Rick Sondermann leads our crew with a direct, no-guesswork approach that’s built on decades of seeing what actually happens when you open up older homes. Our reputation across the 92324 zip code is built on showing up when we say we will and writing contracts that account for what Colton’s houses actually contain.
We’re not a listing service or a broker. We employ and manage the full scope of work, from the roof down to the pavers. When we say we know Colton, we mean we know what the soil does near the foothills on the north side, how the Santa Ana winds hit homes off La Cadena Drive, and what a 1950s ranch off Valley Boulevard typically looks like behind its drywall. That knowledge directly shapes how we bid, how we schedule, and how we protect your budget.
Styles & brands we work with







Residential General Contractor in Colton
When a Colton homeowner calls us for a residential general contractor, they’re usually planning a kitchen remodel, a bathroom gut, a room addition, or a whole-home renovation that touches multiple trades at once. The job starts with a walkthrough and a written scope of work that includes allowances for the things we can’t see until demolition starts. A kitchen remodel in Colton typically runs $14,000 – $45,000 depending on layout changes, cabinetry, and whether we’re moving plumbing or electrical. A bathroom remodel lands between $9,000 and $28,000. Room additions and home additions run $45,000 – $130,000 because they trigger foundation, framing, roofing, and full permit review.
Pre-Construction Inspection and Scope
Before we write your contract, we look at the panel, the subfloor, the foundation, and the roof. That lets us set realistic allowances for code upgrades instead of letting them blindside you mid-project. We’d rather spend an extra hour on the front end than hand you a change order for $8,000 of unexpected rewire work after the drywall is down.
Permits, Drawings, and Structural Work
Colton requires permits for any structural change, and the city’s plan review catches details that add square footage or modify load-bearing walls. We pull permits, coordinate with the inspector, and keep the project moving through rough-in, in-wall, and final inspections without you having to chase anyone down. Your project, managed start to finish.
Hire a General Contractor in Colton
When you hire a general contractor in Colton, you’re buying accountability. The wrong hire is the contractor who quotes the job assuming nothing unexpected happens, then hands you a stack of change orders when the aluminum wiring shows up. That’s not how we work. Colton’s pre-1980s housing stock frequently contains aluminum wiring and underslab plumbing that only surface once walls are opened, and any permitted addition triggers a full inspection sign-off on those systems before the new work can proceed. That’s a cost driver that rarely appears in neighboring newer cities like Grand Terrace or Loma Linda, and any contractor who doesn’t budget for it is setting you up for a stall.
Contingency Allowances Written Into the Contract
We build a contingency line into every Colton contract, and it’s not a blank check. It’s a defined allowance with a written scope of what it covers: electrical upgrades, plumbing corrections, dry rot repair, seismic hold-downs. If we find something beyond that, we stop work and bring you a written change order with updated pricing before we touch another stud. You approve it or you don’t. Nothing moves without your sign-off.
One Team, Full Scope
A home addition in Colton isn’t just framing. It’s foundation work on expansive clay, roofing, electrical, plumbing, stucco, windows, and finishing. We run every trade through our own schedule and our own project manager. No more calling a plumber who blames the electrician who blames the framing crew. From the first excavation to the final paint walk, it’s our name on the job and our phone you call.
Trusted Brands We Service in Colton
We spec materials from brands that hold up under Colton’s heat and UV: James Hardie siding for stucco replacements, KraftMaid and Wellborn cabinetry for kitchens and baths, and Tuff Shed structures for backyard storage or workshop builds that match the property’s existing roofline. Because we order directly through our partner network, we’re not waiting on a big-box order desk. Parts, replacement panels, and warranty items arrive on our schedule, not someone else’s. We’ll guide you to the right material for your budget, and we install everything to the brand’s specification, installed to ours.

AfterCommon General Contractor Problems We See in Colton Homes
- Aluminum branch wiring from the 1960s and 70s. It’s a fire hazard when combined with modern fixtures, and Colton code won’t sign off on an addition without correcting it. We budget for copper rewire runs on any home built before 1980.
- Cast-iron underslab drains that rust and collapse. We’ve found failed drain lines under slab foundations that had been leaking for years. A room addition over that ground means replacing the line before we pour.
- Expansive clay soil near the north foothills. Colton’s soil swells with winter rain and shrinks in summer heat, which cracks foundations and shifts framing. We recommend a soil assessment before any addition.
- Undersized framing for current seismic code. Mid-century Colton homes were built before modern shear wall and hold-down requirements. Open up a wall for a remodel and the inspector will flag it. We catch it early and fix it once.
Pricing for General Contractor in Colton, CA
We believe in giving you real numbers before you sign, not vague ranges that shift once work starts. Here are typical Colton market ranges for common projects:
| Project | Typical Colton Price Range |
|---|---|
| Home Addition | $45,000 – $130,000 |
| Kitchen Remodel | $14,000 – $45,000 |
| Bathroom Remodel | $9,000 – $28,000 |
What moves a kitchen remodel between $14,000 and $45,000? Layout changes, cabinet grade, whether you’re keeping the existing footprint, and what’s behind the drywall. A bathroom at the low end keeps the tub and vanity location and swaps finishes. At the high end, we’re moving walls, replacing subfloor, and running new circuits. Home additions range widely because a garage conversion in Colton runs $30,000 – $80,000, while a second-story addition on an older ranch can hit $130,000 once foundation and seismic work are factored in. Call (855) 473-6535 to schedule your free estimate and get a written line-item quote. Estimates are free, and our fixed-price line items don’t change unless you approve a written change order.

FAQs About General Contractor in Colton
We stop work, bring in a licensed electrician or plumber, and get you a written change order with updated pricing before we proceed. On a recent 1950s ranch off Valley Boulevard, we opened a wall for a room addition and found original aluminum branch wiring and a failed cast-iron underslab drain that had been hidden for decades. The original contract had a contingency allowance for exactly this kind of find. We replaced the circuits with copper and the drain line with new ABS before rough-in, and the project passed final inspection without further surprises. Call (855) 473-6535 to discuss your project and we’ll walk you through how allowances work.
Any room addition in Colton requires a building permit, and if you’re changing the roofline or foundation, you’ll need structural and possibly soil reports. We pull all permits, coordinate with the city, and manage the inspection schedule through rough-in, in-wall, and final. If an inspector flags an existing condition like aluminum wiring or undersized framing, we handle that in the same permit cycle rather than stalling the draw schedule. Call (855) 473-6535 for an exact breakdown of what your project triggers.
Colton’s clay soil swells with winter rains and shrinks in summer heat, which pushes against foundations and can crack slabs. For any addition, we recommend a soil assessment and often specify a post-tension slab or deeper footings than you’d see in coastal cities. Skipping that step is the fastest way to get a foundation crack and failed waterproofing two years after you move in. Call (855) 473-6535 and we’ll explain what your lot needs.
Yes, we provide fixed-price line items for the scope we can see, plus a written contingency allowance for the scope we can’t see until demolition. If we use less than the allowance, you keep the difference. If we find something beyond it, we stop and bring you a written change order with pricing before we touch another stud. You approve it or we don’t do it. Call (855) 473-6535 for a free estimate and a contract that protects you.
A draw schedule ties payments to completed milestones, not dates. You pay for what’s been built and inspected, not what a contractor promises is coming next week. We structure draws around permit approval, rough-in inspection, drywall, and final walk. If we’re waiting on the city, you’re not paying for work that hasn’t been signed off. Call (855) 473-6535 to schedule your free estimate and we’ll explain the schedule for your specific project.
