Fast, Reliable General Contractor Across Castro Valley
When a Castro Valley homeowner calls us about a kitchen remodel, a room addition, or a garage conversion, the first thing we do is ask about the house itself. What year was it built? Does it sit on a slope in Greenridge or Palomares Hills? Has any previous work been permitted? Those answers shape the entire job because Castro Valley sits in unincorporated Alameda County, which means most remodels here go through the county’s Building Services rather than a city building department. We know that process cold, and we’ll walk you through it before you sign anything. Call (903) 568-7222 and we’ll give you a straight read on your project.
Why Bradford Remodeling Is Castro Valley’s Preferred General Contractor Company
Our General Contractor team works under The Garrison Standard, which puts every price and every guarantee in writing before a single tool comes out. That matters in Castro Valley, where homeowners have been burned by bids that looked complete but weren’t. We see it all the time: a written quote for a bathroom remodel that quietly leaves out tile, hardware, and fixtures, or a kitchen bid that never mentions the cabinet pulls. The homeowner finds out after demo day, when the price suddenly grows. We don’t operate that way.
The 365-Day Done Right Promise backs every completed project. If the work fails inside that window, we come back and correct it at no charge. That’s a written guarantee, handed to you at job close along with a documented scope of work and a clean site. No surprises, no open-ended allowances, no “we’ll figure that out later.”
You’ll also reach a live person when you call, 24 hours a day, seven days a week. Not a voicemail tree. Not a callback queue. A real person who can answer your question right then.
Curtis Lane leads our team, and every technician who walks through your door is background-checked and in uniform. You’ll know exactly who’s coming before they arrive.
Styles & brands we work with
Remodeling Contractor in Castro Valley
Remodeling Contractor work in Castro Valley covers the full scope of what we do: kitchens, bathrooms, additions, and whole-home renovations. The first sentence of any conversation should establish what the job actually involves, because that’s where Castro Valley homeowners get burned most often. A real remodeling contractor in Castro Valley needs to pull the right Alameda County permits, account for the home’s age and structure, and price every line item before work starts. That’s exactly how we operate.
A kitchen remodel across Castro Valley typically runs $14,000 to $45,000. A bathroom remodel lands between $9,000 and $28,000. Those ranges reflect what we see across Greenridge, Five Canyons, the Lake Chabot side, and the older neighborhoods west of Redwood Road. The difference between the low and high ends comes down to structural work, layout changes, and materials, not vague “upgrades” buried in the fine print.
Kitchen and Bath Remodels
Older Castro Valley homes, especially those built in the 1960s and 1970s, frequently have load-bearing walls where today’s homeowners want open sightlines. Removing one requires a structural engineer, a new header, and a county inspection before the wall comes down. We price that work into the initial written quote, not as a change order after demolition.
We also run the rough-in for relocated sinks, island plumbing, and new electrical before the drywall goes back up. That timing matters: if the rough-in isn’t inspected first, the county won’t sign off and the walls have to come back open.
Room Additions and Garage Conversions
Additions in Castro Valley’s hillside neighborhoods often trigger geotechnical review because of slope and drainage conditions. A room addition may need soil testing and a grading plan before Alameda County issues the permit. Garage conversions carry their own set of requirements around foundation, insulation, and egress windows, and skipping the permit there is a fast way to create a resale problem later.
Licensed General Contractor in Castro Valley
A Licensed General Contractor in Castro Valley is the person who owns the permit, the schedule, and the final inspection sign-off. We handle all of it. When you hire us for a Castro Valley project, we pull the Alameda County permits, coordinate the trade inspections, and carry the job through the county’s final sign-off. You don’t get handed a list of calls to make.
Home additions run $45,000 to $130,000 across Castro Valley. ADU construction typically lands between $90,000 and $220,000, while a garage conversion runs $30,000 to $80,000. These are big numbers, and they should come with a written scope of work that spells out exactly what’s included: the framing, the rough-in, the finishes, the fixtures, the trim. Our fixed pricing means the number on the contract is the number you pay unless you change the scope yourself.
Permits and Inspections
Alameda County’s Building Services reviews plans, issues permits, and schedules inspections for most Castro Valley work. The process moves differently than in San Leandro or Hayward, where city building departments handle their own permits. Knowing that difference keeps a project from stalling at the counter.
Written Scope and Fixed Pricing
Every Castro Valley project starts with a written price and a documented scope. No numbers that move at the door. No allowances that turn out to be guesses. If cabinet hardware, tile, or fixtures are part of the job, they’re in the written quote from day one.
Trusted Brands We Service in Castro Valley
We install materials from a documented roster so specifications are traceable and quality isn’t left to guesswork. That includes KraftMaid and Wellborn cabinetry, Cambria and Caesarstone surfaces, Kohler and Moen fixtures, GAF and James Hardie exterior products, Therma-Tru doors, and Belgard hardscaping. We’ve also worked with product lines from Cover and Dvele on specific Castro Valley projects where pre-fabricated or panelized components made sense. When a homeowner wants a particular brand, we can source it and write it into the contract by model number. No bait-and-switch on materials, ever.

AfterCommon General Contractor Problems We See in Castro Valley Homes
- Unwritten scope of work. A bid says “kitchen remodel, $22,000” but doesn’t list cabinet hardware, tile, or fixtures. The homeowner discovers after demo that those items were never included. We write every line item before you sign.
- Skipped or deferred Alameda County permits. Some contractors assume unincorporated Castro Valley means no permits are required. That’s false, and the homeowner ends up with open permits at resale or a failed inspection later. We pull permits on every job that requires one.
- Change orders after demolition. Older Castro Valley homes frequently have subfloors or rough-in that don’t match the original plans. A contractor who didn’t account for that will reprice the job once the walls are open. We anticipate those conditions and price them into the original quote.
- Unmatched finishes after patch work. When a new header goes into a 1970s home, the surrounding trim and subfloor rarely match what’s on the shelf. We patch the original materials and match the existing profile so the job looks like it was always there.
We handled a kitchen remodel in the Greenridge neighborhood where the original 1970s layout had a load-bearing wall between the kitchen and dining room. After our general contractor confirmed the span with a structural engineer, we pulled the Alameda County permits, installed a new header, and ran the rough-in for a relocated sink and an island with a Kohler faucet and Cambria countertop. The punch list included patching the original oak subfloor and matching the existing trim, and the county’s inspection sign-off on the framing and electrical cleared before we closed up the walls.

FAQs About General Contractor in Castro Valley
Yes, most kitchen and bathroom remodels in Castro Valley require permits through Alameda County’s Building Services, not a city building department. Castro Valley is unincorporated, which means the county reviews plans and issues permits for most structural, electrical, plumbing, and mechanical work. Skipping the permit creates open-permit issues at resale and can fail inspection if the work is discovered later. We pull the permits and manage the inspections as part of the job. Call (903) 568-7222 to get your project scoped and permitted correctly.
The main cost drivers are structural changes, layout moves, and material grade. Removing a load-bearing wall, relocating a sink or range, and adding an island with stone countertops push a kitchen toward the upper end of the $14,000 to $45,000 range we see in Castro Valley. A cabinet-and-countertop refresh on a flat-lot home on the west side lands lower. Hillside homes in Palomares Hills or Five Canyons may add geotechnical review and drainage work to the total. We write every driver into the initial quote so you see exactly what you’re paying for.
A kitchen or bathroom remodel in Castro Valley typically runs six to ten weeks from signed contract to final punch list, assuming the scope doesn’t change. Structural work, hillside geotech review, and Alameda County inspection scheduling can extend that. A room addition or ADU often runs four to eight months. We give you a written schedule at contract signing and update you as inspections clear. The 365-Day Done Right Promise covers the work for a full year after we hand you the signed guarantee.
Only a change you request changes the price. Our written quote includes the full scope: materials, allowances, rough-in, finishes, and trim. If you decide mid-project to upgrade from a standard vanity to a custom one, or add a new circuit, we write a change order you approve before we proceed. That’s the only time the number moves. Unpriced change orders after demolition are not how we work in Castro Valley. Call (903) 568-7222 and we’ll show you a written quote with the full scope before you commit.
We handle both. Our team pulls the Alameda County permits, schedules the inspections, and carries the job through final sign-off. You don’t need to file anything or chase the county. At close, we hand you a signed written guarantee under the 365-Day Done Right Promise and a documented scope of work showing what we built and what it covers.
If you’re planning a remodel in Castro Valley, call (903) 568-7222 and we’ll give you a straight price in writing. The estimate is free. The scope is documented. The guarantee is for a full year.
