Fast, Reliable General Contractor Across Montclair
Montclair homeowners call us when the job is too big to guess at. We’re Bradford Remodeling Co Riverside, and we handle general contracting across Montclair with a straight price in writing before the first tool hits the truck. Most of our Montclair work sits in the older ranch and Spanish-style homes between Holt Boulevard and the 10 Freeway, and a good share of it runs up into the northern foothills where acreage lots and county requirements change how a project gets scoped. Curtis Lane runs our crews, and every job closes with a signed written guarantee in your hand. Call (424) 567-8472 for a free estimate.
Why Bradford Remodeling Co Riverside Is Montclair’s Preferred General Contractor Company
Montclair homeowners tend to be past the point of giving a contractor the benefit of the doubt. They have seen the no-show, the reprice at the door, the half-finished rough-in left under a tarp. What changes the conversation is a price that does not move and a guarantee that has a name on it. Ours is the 365-Day Done Right Promise. If completed work fails inside a year, we return and correct it at no charge. That is written into the contract, not implied.
Every Bradford technician who walks onto a Montclair property is background-checked and uniformed. You know who is coming before they park. The Garrison Standard, which Curtis Lane enforces on every job we run, puts this in writing: written price before work starts, documented scope, clean site at close. No exceptions, no “the market shifted” conversation at the punch-list walk.
We coordinate dispatch from our Inland Empire office, and our crews know Montclair’s specific pain points: slab foundations on expansive clay, aging cast iron supply lines, and the county permitting maze that comes with acreage work in the foothills. That local knowledge is not marketing copy. It is how we scope a job so the change order does not eat your contingency.
Styles & brands we work with
Hire a General Contractor in Montclair
Hire a General Contractor in Montclair when the work touches structure, grading, permits, or more than two trades. We are not a handyman service that adds a surcharge for complexity. We are the crew that pulls the county permit, schedules the structural engineer, coordinates the plumber and the electrician, and stands behind the result for a full year. On Montclair’s older housing stock, that often means dealing with what is behind the wall: cast iron drain lines, ungrounded wiring, drywall cracks from shifting slab foundations. The common thread is that none of it gets discovered after the contract is signed. We open the wall in the scope phase, not on day eleven.
Whole Home Remodel
A whole-home remodel in Montclair typically runs $45,000 – $130,000 depending on square footage and condition. Older 1950s and 1960s ranches in the flatlands often hide corroded galvanized supply lines and original electrical panels that need replacement before finish work can start. We price those discoveries into the written estimate.
Room Addition
Adding square footage in Montclair means dealing with the slab, the soil, and San Bernardino County setback rules. A room addition runs $45,000 – $130,000, and on foothill lots the grading and drainage can shift the number as much as the framing. We scope the site before we quote, not after.
General Contractor Services in Montclair
General Contractor Services in Montclair cover more than swinging hammers. Our crews also coordinate the utility locates, the material deliveries, the traffic control on narrow foothill roads, and the Caltrans-adjacent noise and dust barriers when the job sits within earshot of the 10 Freeway. On acreage lots, that can mean hauling a mini excavator up a slope with no turnaround, digging a bench into the hillside, and managing a spoil pile without wrecking the neighbor’s swale. We handle that end to end.
Garage Conversion
A garage conversion in Montclair runs $30,000 – $80,000. Older single-car garages on slab foundations often need a structural upgrade to meet current live-load code. If the garage was built before the 1980s, expect a conversation about pulling new electrical and possibly replacing the slab edge where spalling has started.
ADU Construction
ADU construction on a Montclair acreage lot runs $90,000 – $220,000, and the wide range is driven mostly by the site. County septic and well setbacks, slope stability, and equipment access define the budget before the first wall goes up. We do the site walk, the county as-built pull, and the written scope as one package.

AfterCommon General Contractor Problems We See in Montclair Homes
- Slab cracks from expansive clay. The Pomona Valley’s clay soils shrink in summer and swell after winter rains. We see the result in cracked stucco, sticking doors, and drywall seams that open and close with the season. Repair means stabilizing the soil and re-floating the wall, not just patching the crack.
- Corroded galvanized supply lines. Homes in the ‘H’ section of Montclair, between Holt Boulevard and the 10 Freeway, often still carry original galvanized supply lines. The mineral-heavy local water has eaten them from the inside, and pinhole leaks under slabs are a recurring call. Repiping is the fix.
- Cast iron drain failures. 1950s and 1960s cast iron drains have a lifespan, and many Montclair homes are past it. We scope with a camera before quoting, because a belly in the line under the slab changes the entire remodel budget.
- Acreage setbacks and county permitting. Foothill lots developed before modern grading codes often fail current San Bernardino County setback separation for septic and wells. Any new detached structure forces a site rethink, and we pull the county as-builts before we quote so you do not eat design fees on a permit that will not issue.

FAQs About General Contractor in Montclair
Yes, acreage work in Montclair’s northern foothills falls under San Bernardino County permitting, not city review, and a detached shop or ADU almost always requires a full site plan, a grading review, and septic or well setback verification. County as-builts drive the decision, so we pull them before we write a quote. Call (424) 567-8472 and we will scope the permit path with you at no charge.
Current county rules generally require a 100-foot separation between a leach field and a new structure, but your parcel’s recorded easements and as-built drawings control the actual number. Many pre-1970 foothill lots do not meet that separation as platted, which forces a redesign, not just a smaller footprint. We pull the county file before you spend money on plans.
Montclair sits on expansive clay that swells when winter moisture gets under the slab edge, and the swell lifts the foundation unevenly. The crack you see in the drywall is the symptom; the fix is often better drainage, a deepened perimeter drain, or soil treatment under the slab, not just a drywall patch. Call (424) 567-8472 for a site evaluation.
Yes, a slab foundation does not rule out a garage conversion, but the existing slab often needs edge thickening or a structural overlay to meet current live-load code for a dwelling. We typically cut test holes and review the original pour thickness before pricing, so the written quote reflects the structural work, not a surprise later. Conversions in Montclair run $30,000 – $80,000.
Include the exact scope of grading and drainage work, the septic and well setback verification, a written allowance for soil overexcavation if clay is found, and a clause that ties change orders to the written contingency figure. Bradford puts all of that in writing before the first stake goes in, and our 365-Day Done Right Promise covers the completed work for a full year. Call (424) 567-8472 for a free estimate.
