Fast, Reliable General Contractor Across Bloomington
If you’re planning a remodel, addition, or detached ADU on a Bloomington lot, the first thing you need is a contractor who understands how San Bernardino County permits and inspections actually work here. We’ve been building in Bloomington long enough to know that a bid built on Fontana timelines won’t survive contact with the county review desk. San Mateo Construction handles the whole scope under one contract, from county records checks to final inspection sign-off. Call us at (855) 901-7266 and we’ll walk your property and give you a straight answer on cost and schedule.
Why San Mateo Construction Is Bloomington’s Preferred General Contractor Company
Bloomington homeowners keep calling us back because we scope the job the way it actually runs here, not the way it runs in a neighboring city. We know the difference between a Fontana city permit and a San Bernardino County Land Use Services review, and we know which one applies to your address. That matters on a detached ADU or shop build where county lot-coverage rules are often more forgiving than Fontana or Rialto, but the review path is longer and more document-heavy. Our General Contractor team has pulled county records for dozens of these projects, and we always check for unpermitted prior work before we quote a remodel or addition.
Noel Carrington runs our projects with the understanding that Bloomington’s older housing stock carries hidden conditions: mid-century stucco framing that’s settled, owner-built additions that never saw an inspector, decomposed-granite soil that drains poorly once winter rain hits. We price those in from the start rather than treating them as surprises mid-job. Homeowners who’ve worked with us in Bloomington say the same thing: the quote held, the schedule held, and the county sign-off came through.
Styles & brands we work with







General Contractor Services in Bloomington
General Contractor Services in Bloomington means more than swinging a hammer. It means managing the county permit path, the septic and well setback checks, the grading and drainage plan, and the materials coordination for a job that might start at the roofline and end at the foundation. A whole-home remodel here typically runs $45,000 to $130,000 for an addition, and a detached ADU starts around $90,000 and can reach $220,000 depending on septic, grading, and site access. We pull county records before quoting so the number you get is the number you can build to.
Whole-Home and Room Additions on Older Lots
Most Bloomington additions land on 1960s or 1970s stucco homes with generous setbacks and ad hoc add-ons from prior owners. We match the newer framing to the older structure, excavate for footings on compacted decomposed granite, and coordinate the county inspection schedule before drywall goes up. A room addition here runs $45,000 to $130,000, and the biggest wildcards are usually drainage and what we find when we open the existing wall.

Detached ADUs and Shop Buildings
On the larger lots off Valley Boulevard and the old farm-road grid, a detached ADU or shop is often the single best move a Bloomington owner can make. The county allows lot coverage that city rules in Fontana and Rialto would block outright. ADU construction in Bloomington runs $90,000 to $220,000. Garage conversions are $30,000 to $80,000. We handle the well and septic setback review, the site plan, and the equipment access assessment before we ever quote a number.

Construction Company in Bloomington
Construction Company in Bloomington should mean one accountable team across every trade, not a parade of subs you didn’t choose and can’t hold responsible. San Mateo Construction carries the full scope: we re-roof the house, replace the windows, remodel the kitchen, and pour the driveway under the same contract. That’s the difference between a coordinated build and a jobsite full of finger-pointing. One contract, one schedule, one point of contact, and the county inspector knows who pulled the permit.
Exterior Systems and Hardscape
Bloomington’s dry heat and Santa Ana winds crack stucco, curl old roofing, and stress concrete flatwork. We run GAF and CertainTeed roofing, PGT windows, James Hardie siding, and Belgard or Techo-Bloc hardscaping so the exterior holds up under inland-empire sun. A concrete driveway runs $4,500 to $12,000. A paver driveway is $7,000 to $18,000. We grade and drain every horizontal surface so winter rain doesn’t undermine what summer heat already stressed.
Kitchen and Bath Remodels with Real Material Selection
We help Bloomington owners choose from vetted brands across every system, not whatever’s left at the supply yard. Countertops come from Cambria, Silestone, or Caesarstone. Fixtures from Kohler, Grohe, Toto, or Moen. Cabinetry from KraftMaid or Wellborn. You’re choosing from a curated list with honest material tiers so you don’t overpay for premium where value-tier does the job. A kitchen remodel in Bloomington runs $14,000 to $45,000, and a bathroom remodel runs $9,000 to $28,000.
Trusted Brands We Service in Bloomington
We carry relationships with 50+ manufacturers across roofing, windows, cabinetry, countertops, plumbing, siding, hardscaping, fencing, and ADU systems. That includes PGT windows and doors, and we work with manufacturers like Abodu, Dvele, and Boxabl on prefab ADU builds for Bloomington lots where site access makes stick-built slow. For Bloomington homeowners, that means we can source the right system for the condition of your house and the realities of your lot. You get name-brand components with local availability and our install crews who know how those systems hold up in inland-empire climate.

AfterCommon General Contractor Problems We See in Bloomington Homes
- Unpermitted owner-built additions. The back garage or add-on that was never permitted is the single most common discovery on Bloomington’s older lots. We run county records before demolition so we’re never surprised mid-framing.
- Decomposed-granite drainage failures. The same soil that compacts hard in summer turns unworkable and erosive in winter rain. Footings and flatwork planned without grading fail within a season or two.
- County permit timelines baked into city-style bids. A quote built on Fontana or Rialto review speeds is wrong the day it’s written. County Land Use Services review is the first schedule variable on any Bloomington ADU, shop, or addition.
- Septic and well setbacks on acreage lots. A detached ADU can’t simply go where the yard looks open. Setback distances from existing septic systems and wells often dictate the buildable envelope and drive cost before design even starts.

FAQs About General Contractor in Bloomington
Because every plan, inspection, and site check runs through San Bernardino County Land Use Services rather than a city building department. That review path is slower and more document-heavy than Fontana or Rialto, and it adds real scoping time before a number can be locked. A bid that skips that step is wrong before ground is broken. Call (855) 901-7266 and we’ll tell you what the county will actually need for your address.
Yes, every time. We run the county records check before we quote because nearly every older Bloomington property has some owner-built structure that was never permitted. Finding that early means the quote accounts for correcting it; finding it after demo starts means a change order. We’ll pull the records, walk the property, and give you a number that holds.
On acreage lots, your septic system and well have required setback distances that dictate where a new structure can sit. That often shrinks the buildable envelope more than the lot lines do. We verify those distances during scoping so the ADU or shop lands where the county will approve it, not where the yard happens to look open. Call for a free site assessment.
Bloomington’s decomposed-granite soil compacts hard in dry months and erodes in winter rain. A proper addition needs graded compaction, positive drainage away from footings, and often a swale or dry well to handle storm runoff. Skimping there means failing footings and cracked flatwork within a season or two. We price grading and drainage as a line item, not an afterthought.
We match the new framing to what the house actually has, which means opening walls carefully, checking settled headers and sills, and repairing before we close anything up. Older stucco gets matched in texture and color so the newer work doesn’t look like a patch. Our crews have done enough Bloomington remodels to know where these older homes hide their problems. Call (855) 901-7266 to schedule a free estimate and we’ll show you what we see.
