Fast, Reliable General Contractor Across Bloomington
Finding a General Contractor who understands Bloomington means finding someone who works with San Bernardino County rules, not a city hall. That distinction changes permit timelines, inspection schedules, and how a project gets scoped from day one. Iron Beam Contractors has run jobs across the 92316 zip code long enough to know where the county holds the line and where it doesn’t. Call (833) 756-5936 and you’ll speak with Nolan Driscoll, who will give you a straight answer before anyone shows up to walk your property.
Why Iron Beam Contractors Is Bloomington’s Preferred General Contractor Company
Bloomington homeowners call us for one reason more than any other: we pull the right permit through the right agency before the first wall comes down. A job permitted through San Bernardino County is not the same as one permitted through the City of Fontana, and if your contractor hasn’t done both, you’re paying for their learning curve. We have. Our team has managed additions, garage conversions, roof replacements, and ADUs on parcels throughout Bloomington, from Cedar Avenue properties with detached rear shops to corner lots off Valley Boulevard.
We’re not a broker who hands your project to a rotating cast of subs. Nolan Driscoll carries the project from the initial walk to final inspection. When a homeowner brings us a 1960s shop that was never permitted, the conversation starts with county compliance, not a sales pitch. That’s the difference between a contractor who has worked here and one who is figuring it out on your dime.
Response time matters when you’re scheduling around county plan review. We commit to a documented timeline for every Bloomington project and update you as the county moves through its review cycles.
Styles & brands we work with







Residential General Contractor in Bloomington
A Residential General Contractor in Bloomington handles the full scope of a home renovation or addition: demolition, framing, electrical, plumbing, roofing, and finishes, all under one contract and one point of contact. Most Bloomington homes are 1950s to 1970s single-story stucco tract homes with slab foundations, plus a generous share of rural-residential lots with detached garages and rear accessory shops. That housing stock dictates what we see when walls open: older wiring, failing vapor barriers, and framing that predates current shear-wall requirements for this seismic zone.
Home additions in Bloomington typically run $45,000 to $130,000 depending on square footage, foundation work, and whether the county requires structural upgrades to the existing structure. A garage conversion runs $30,000 to $80,000. Those ranges assume a permitted job. If the space you’re converting was never permitted, add the cost of as-built drawings and county compliance review.
Building on Acreage
Bloomington has more open-lot, rural-residential parcels than its incorporated neighbors. Building on acreage means we’re checking well and septic setbacks before we stake anything, and we’re hauling material and equipment across longer distances. Grading and drainage on an open lot often decides whether a pad holds or a patio slab cracks, so we walk drainage before we quote.
Retrofitting Aging Structures
Most Bloomington homes carry decades of sun, wind, and deferred maintenance. A remodel on a 1960s wood-frame home usually means a new electrical panel, subfloor repairs, and stucco remediation once we open walls. We carry allowances for those conditions instead of pretending they won’t appear.
Hire a General Contractor in Bloomington
When you Hire a General Contractor in Bloomington, you’re hiring someone to manage the trades, the materials, the permit file, and the inspection schedule. On a county-permitted job, that coordination is heavier than it looks. San Bernardino County plan review and inspection sign-off have their own rhythm, and a contractor who doesn’t respect it will burn your summer waiting on a permit that a competent operator would have staged properly.
ADU construction in Bloomington runs $90,000 to $220,000 on a prepared lot. That includes county plan review, foundation or slab work, utility connections, and all finishes. Roof replacement runs $8,000 to $20,000 depending on roofing system and whether we’re tearing off one layer or two. A concrete driveway installation runs $4,500 to $12,000, with early-morning pours scheduled in summer to beat the heat.
One Contract, Every Trade
Iron Beam runs interior remodeling, exterior envelope work, outdoor hardscape, and ADU or prefab installation under one contract. That means one draw schedule, one warranty conversation, and one person accountable when the county inspector asks a question. No chasing a framer who never met your electrician.
Specified for Longevity
We specify materials for how long they’ll last under Bloomington’s sun and wind, not for how they photograph. On roofing we can source GAF, CertainTeed, Owens Corning, and IKO systems. On stucco and exterior work we account for UV and Santa Ana wind-driven grit. On plumbing and cabinetry we work from brands our clients can actually see and touch before we order.
Trusted Brands We Service in Bloomington
Iron Beam is authorized to work with more than 50 named material and product brands, and for Bloomington jobs we lean on systems built for the Inland Empire climate. That includes roofing brands such as GAF, CertainTeed, and Owens Corning when we’re replacing a roof that has taken a decade of sun. We stock nothing in a Bloomington warehouse, but we order and stage material locally, stage deliveries to avoid blocking narrow rural driveways, and handle warranty registration through the manufacturer, not a third party. Built on real brands, real standards.

AfterCommon General Contractor Problems We See in Bloomington Homes
- Unpermitted additions and shops. We regularly see rear garages, carports, and accessory buildings that a previous owner or a family member built decades ago without county approval. When the property sells or gets refinanced, those structures have to be legalized, and that changes the scope from simple remodel to as-built drawing and county plan review.
- Older electrical panels on aging wood-frame houses. Most Bloomington homes from the 1950s through 1970s still carry original or undersized panels. Any substantial remodel or ADU triggers a panel upgrade and often a service change, which we carry as an allowance rather than a surprise change order.
- Slab-on-grade foundation movement. The county’s expansive soil and decades of wet-dry cycles leave a lot of Bloomington slabs with hairline cracking. Before we set cabinets, tile, or a new addition on an existing slab, we check flatness and moisture so the finish doesn’t fail a year later.
- Stucco and exterior sun damage. Intense UV, summer heat above 100°F, and blown dust from the Cajon Pass beat up exterior paint, stucco, and roofing faster than homeowners expect. We scope exterior repairs with that exposure in mind rather than treating Bloomington like a coastal climate.

FAQs About General Contractor in Bloomington
Bloomington is an unincorporated San Bernardino County island, so every permit runs through County of San Bernardino plan review instead of a city building department. That means extra review cycles and county inspection sign-off that a Fontana or Rialto job doesn’t carry. We build that time into the schedule before we quote.
Call (833) 756-5936 and we’ll outline the county timeline for your specific project.
Yes. We order as-built drawings of the existing structure and run a County of San Bernardino compliance review before any new work begins. The structure gets inspected to current code where it matters for safety, and we fix what the county flags. This process adds cost and time, but it’s the only path to a legal structure when you sell or refinance.
Call (833) 756-5936 for a compliance review on your property.
Setbacks dictate where a new structure can sit on your lot, and they are not negotiable with the county. We verify well location and septic system placement during our first site walk, then design the ADU or shop footprint around those lines. Getting this wrong means moving a building pad after you’ve paid for plans, so we confirm it before anything is staked.
Call (833) 756-5936 and we’ll walk your lot before you spend a dollar on design.
Summer temperatures regularly pass 100°F here, and concrete placed in midday heat cures too fast and loses strength. We schedule pours at 6 a.m. and stage material deliveries before the heat builds. Exterior stucco and roofing follow the same logic: we work the cool window and avoid wind-driven dust when we can.
Call (833) 756-5936 to schedule your project around Bloomington’s summer heat.
It’s a line-by-line document: demolition, foundation, framing, electrical, plumbing, roofing, drywall, finishes, and a named allowance for unknowns like panel upgrades or subfloor repair. Every brand we plan to source is named. The county permit fee is listed separately. You see the whole job before you sign anything.
