Fast, Reliable General Contractor Across Bloomington
If you’re searching for a General Contractor in Bloomington, you already know the headaches that come with remodels in an unincorporated community. Permits run through San Bernardino County Land Use Services rather than a city hall, and older homes off Cedar Avenue or around Bloomington High School often hide wiring and framing issues behind walls that have been there since the 1960s. Polaris Contractors handles the full scope under one agreement, from opening the first wall to final county inspection. Rick Sondermann leads our team, and he’ll tell you straight what a project should cost and what surprises to plan for. Call (855) 473-6535 to schedule your free estimate.
Why Polaris Contractors Is Bloomington’s Preferred General Contractor Company
Most Bloomington homeowners we work with have lived in the same house for two decades or more. They’ve added rooms, converted garages, enclosed patios, and hired different guys for each job because no single contractor covered everything. That’s exactly why our full-scope approach fits this community: one team accountable for the kitchen, the roof, the windows, the fence, and even a prefab ADU if the family needs more room.
We’ve earned our reputation in the 92316 zip code by being direct about what a remodel actually costs when the walls come open. Rick Sondermann has walked enough Bloomington jobsites to know what the county inspector will flag on a 1950s ranch versus a 1970s stucco tract home. Our quotes include allowances for code upgrades and concealed damage, so you’re not blindsided by a change order you never saw coming.
We respond quickly to Bloomington. Whether you’re off Valley Boulevard near the I-10 or deeper in the residential streets around Mary B. Lewis Elementary, we’re a short drive from our Newport Beach office and schedule visits when you’re actually home. Our General Contractor team manages the entire project with written line-item pricing, county permits, and inspections passed before we call the job done.
Styles & brands we work with







Construction Company in Bloomington
A Construction Company in Bloomington has to work with San Bernardino County rules, not a city building department. When a homeowner calls us about an addition, a garage conversion, or a structural repair, the first thing we check is whether the parcel has legacy unpermitted work that will surface during plan review. That’s not a roadblock, it’s just how Bloomington works. We handle permit applications, county inspections, engineering when required, and all construction under one contract.
Room additions in Bloomington generally run $45,000 – $130,000 depending on square footage, foundation type, and whether you’re extending an existing roofline or building a separate structure. Garage conversions typically land between $30,000 and $80,000 once you account for insulation, electrical, plumbing, and bringing the space up to current code.
County Permits and Legalization
San Bernardino County Land Use Services reviews every permit application for consistency with what’s actually on the parcel. If a previous owner enclosed a patio without permits, the county can flag it before approving your new kitchen or addition. We walk you through the legalization process, document existing conditions, and fold required corrections into the project scope with clear pricing.
Additions and Multi-Generational Builds
Bloomington has a high share of multi-generational households, and that shapes the work. A junior ADU or converted garage becomes a separate living space for adult children or aging parents. We build to current county standards for egress, fire separation, and ventilation so the space is legal, comfortable, and safe.
Remodeling Contractor in Bloomington
A Remodeling Contractor in Bloomington is only as good as their inspection process. Before we quote a kitchen or bathroom, we look inside the walls where we can: behind the stucco, under the sink, in the attic. Older Bloomington homes built between the 1950s and 1970s commonly have cloth-sheathed wiring, undersized floor joists, or headers that were notched by a previous handyman. We price those realities into the project from day one.
Kitchen remodels in Bloomington typically run $14,000 – $45,000. A smaller kitchen with basic cabinetry and counters can start around $9,000 – $20,000. Bathroom remodels fall between $9,000 and $28,000, while a straightforward tub-to-shower conversion runs $3,500 – $10,000. Cabinetry from KraftMaid or Wellborn, quartz from Cambria or Silestone, and fixtures from Kohler or Grohe all influence the final number, and we’ll guide you to the material tier that matches how long you plan to live in the house.
Kitchen and Bath Remodels
When we open a 1960s Bloomington kitchen, we expect surprises. On a ranch off Cedar Avenue near the Rialto border, we found cloth wiring and a load-bearing header that had been notched for a previous unpermitted addition. We pulled the county permit, added engineering for a proper beam, and included a written change order for the electrical rough-in and framing repairs before any drywall went back up. That’s how we run every project: document, price, approve in writing, then build.
Whole-Home Updates
Many Bloomington homeowners choose to tackle multiple systems at once rather than piecemeal projects. A whole-home remodel might include James Hardie siding, new windows from PGT or CGI, a GAF or Owens Corning roof, and updated hardscaping with Belgard pavers. We coordinate all of it under one project agreement so you’re not juggling three contractors and wondering who’s responsible for what.
Trusted Brands We Service in Bloomington
Polaris Contractors brings curated access to 50+ vetted brands, and we stock common parts and materials for Bloomington jobs so turnaround stays tight. For cabinetry, we work with KraftMaid and Wellborn, both known for holding up through decades of daily use. James Hardie siding is a frequent choice for Bloomington exteriors because it handles the intense summer sun and Santa Ana wind cycles better than most materials. When a Bloomington homeowner needs a structure for a small lot, Tuff Shed offers a practical footprint for storage or a workshop, whether detached or integrated into a larger project. We’ll match the right brand to your budget and your long-term plans, not just default to whatever’s cheapest.

AfterCommon General Contractor Problems We See in Bloomington Homes
- Unpermitted additions and conversions: Garage conversions, enclosed patios, and bump-out rooms built without county permits are extremely common on older Bloomington parcels. These must be legalized before a sale, refinance, or any new permitted work.
- Cloth wiring and outdated electrical: Homes built before the mid-1970s frequently have cloth-sheathed wiring that no longer meets code. Opening a wall for a kitchen or bathroom triggers electrical upgrades that a generic quote never includes.
- Notched or undersized framing: Previous owners sometimes cut into load-bearing headers or floor joists to run plumbing or ductwork. The county inspector will flag this, and the repair becomes part of the project scope with written pricing.
- Stucco and roofing stress from Santa Ana winds: Bloomington sits east of the Cajon Pass, so homes take real wind and heat cycles. Exterior cracks, lifted shingles, and failed flashing are the result, and exterior envelope work needs to be coordinated, not patched piecemeal.

FAQs About General Contractor in Bloomington
Yes. Bloomington is unincorporated San Bernardino County, so every room addition, ADU, and structural change requires a permit through San Bernardino County Land Use Services, not a city building department. We pull all permits, schedule inspections, and handle corrections before the job closes. Call (855) 473-6535 for guidance on your specific parcel.
We build allowances into the contract for exactly these discoveries, document what we find with photos and written descriptions, and present you with a priced change order before any corrective work begins. You approve the scope and cost in writing, then we proceed. Nothing hidden, no surprise at the end. Call (855) 473-6535 to talk through how this works on your project.
Common triggered upgrades include replacing cloth-sheathed wiring, adding fire-rated assemblies where required, upgrading undersized floor joists, and correcting notched or damaged structural headers. The county inspector will flag these during plan review or rough-in inspection. We include realistic allowances for them in the initial quote, so the cost is understood from the start. Call (855) 473-6535 for an estimate that accounts for your home’s actual condition.
Yes. Legalizing unpermitted work is a routine part of many Bloomington projects. We document existing conditions, work with San Bernardino County Land Use Services to determine what’s required for compliance, and complete the retrofit work with permits. This is often necessary before a sale, refinance, or new addition can be approved. Call (855) 473-6535 to schedule a consultation on your specific property.
Payments are tied to completed milestones, and every change order is written, priced, and approved by you before the work starts. We don’t proceed on verbal approvals. Draw schedules are set before construction begins, so you always know what’s being paid for and when. Call (855) 473-6535 for a project estimate with clear payment terms in writing.
