Hiring a General Contractor in Thousand Oaks means trusting someone with your home, your schedule, and your money.

Just a fixed, written number, a crew you’ll recognize by name and photo before they arrive, and a 365-Day Done Right Promise that backs every project. If you’re planning a remodel, addition, or repair in Thousand Oaks, call (805) 309-3386 for a free written estimate.
Construction Company

A construction company in Thousand Oaks is the licensed entity that carries your project from drawings to final inspection, and Mason Remodeling Co Thousand Oaks has done exactly that since 2004 as part of the Threshold Group family of home-service companies. When you need structural work, additions, or a full remodel, the right construction company handles permits, scheduling, subcontractors, and quality control so you don’t have to. Kitchen remodels in Thousand Oaks typically run $14,000 – $45,000, while a full addition can cost $45,000 – $130,000 depending on square footage and finishes. We don’t guess at those numbers, and you won’t either, because you’ll have them in writing before the first tool is unpacked.
Permit Handling and Inspections
Thousand Oaks follows Ventura County building codes, and pulling the right permits for a remodel or addition is not optional. We handle permits, schedule the required inspections, and make sure the final sign-off happens before you write the last check. If an inspector flags something, we fix it and reschedule without drama.
Subcontractor Coordination
Electrical, plumbing, tile, drywall: a construction company manages the trades so the job doesn’t stall while you’re playing phone tag. Every subcontractor we bring into your Thousand Oaks home is held to the same Threshold Standard we hold ourselves to. You’ll know who is coming, and they’ll show up in a clean uniform with a photo ID badge.

Remodeling Contractor
A remodeling contractor is who you hire when the house works but the kitchen doesn’t, or the bathroom feels like it belongs in 1987, or the whole flow of the home fights your family’s daily routine. Mason Remodeling Co Thousand Oaks is a remodeling contractor that leads with a written price on every project, from small bathroom refreshes at $5,000 – $12,000 to full kitchen gut renovations at $14,000 – $45,000. The difference you’ll notice on day one is that you’re not guessing what the final bill looks like. You’ll have it on paper before we start, because that’s how Isaac Pruett has run Mason Remodeling since 2004.
Kitchen and Bath Specialists
We live in the two rooms that matter most for resale value and daily comfort. A walk-in shower installation in Thousand Oaks runs $4,500 – $12,000, and cabinet installation lands between $4,000 and $13,000. We spec cabinets from KraftMaid and Wellborn and surfaces from Cambria and Silestone, so you’re choosing from proven product lines, not whatever happened to be on clearance.
Whole-Home Remodeling
Sometimes the right move is to change how the entire home lives, not just one corner of it. We handle whole-home remodels with the same written-price discipline and the same 365-Day Done Right Promise that covers smaller jobs. You’ll get one point of contact, one schedule, and one written guarantee at the end.
Licensed General Contractor

A licensed general contractor in California carries the state credential required to perform or coordinate residential construction work valued at $500 or more, and our General Contractor Maintenance Checklist for Thousand Oaks Homeowners can help you prepare for your project. Mason Remodeling Co Thousand Oaks holds that license and has carried it on every project across Thousand Oaks since 2004. You need a licensed general contractor for any project involving structural changes, plumbing relocation, or electrical work, and that covers most kitchen and bathroom remodels. Countertop installation in Thousand Oaks runs $2,000 – $6,500 and backsplash installation $800 – $2,500, and both are jobs where a licensed contractor keeps the work code-compliant and warrantied.
Why Licensing Actually Matters
An unlicensed operator can’t legally pull permits, can’t carry the required workers’ compensation insurance, and leaves you holding the bag when something goes wrong. We’re state-licensed and insured, and every crew member is background-checked and identity-verified before they ever see your address. That’s the baseline, not a perk.
Written Contracts and Clear Terms
Every Mason Remodeling project starts with a written contract, a written price, and a written guarantee with its terms stated plainly. You’ll know what’s covered, what’s excluded, and how long the guarantee runs: 365 days from the completion date. If something isn’t right in that window, we come back and make it right at no cost to you.
Residential General Contractor
A residential general contractor focuses on the homes people actually live in, not retail suites or office buildouts. If you’re in the neighboring community, we also serve as an Oak Park General Contractor. Mason Remodeling Co Thousand Oaks has worked exclusively in residential Thousand Oaks since 2004, so we understand the quirks of Conejo Valley construction: hillside lots, older tract homes built in the 1960s and 1970s, HOAs with strict exterior standards, and water pressure that varies block to block. Driveway replacement in Thousand Oaks runs $5,000 – $14,000, and a paver patio installation lands between $3,500 and $11,000, both jobs where local knowledge changes how we bid and build.
HoA and Local Compliance
Thousand Oaks has active homeowners associations, and they don’t love surprises. We know what local HOAs typically require for exterior work like driveways, patios, and fences, and we factor that into the plan before the first permit is pulled. It saves you the headache of a stop-work notice from your own HOA.
Working Around Homes That Are Lived In
You’re not moving out for a remodel, and we don’t expect you to. We seal off work areas, protect flooring, and keep the jobsite clean at the end of every day. Parents with young children and older adults who are home during the day are exactly the customers we’ve built this process around.
Hire a General Contractor

When you hire a general contractor in Thousand Oaks, you’re hiring the person who is legally and financially responsible for the entire project, from first demolition to final walkthrough. That’s the role, and Mason Remodeling Co Thousand Oaks takes it seriously enough to put every price in writing before work begins. A tub-to-shower conversion in Thousand Oaks runs $3,500 – $10,000, and a kitchen island installation ranges from $3,000 to $10,000, but the number you care about is the one on your written estimate. That’s the number we honor.
What to Ask Before You Sign
Ask for a written price, ask for the license number, and ask what the guarantee covers and for how long. We answer all three before you commit to anything, because Isaac Pruett built this company on the idea that a handshake shouldn’t replace a piece of paper. You’ll get the contract, the price, and the guarantee terms upfront.
Verification Before Arrival
The Threshold Standard is our named, trademarked process for proving who is coming to your door. You’ll receive the technician’s name and photo before the visit, and the same person shows up in a clean uniform with a photo ID badge at your door. That’s not a courtesy. It’s how we’ve worked since 2004.
General Contractor Services
General contractor services in Thousand Oaks cover the full range of residential construction: kitchens, bathrooms, additions, driveways, patios, windows, roofs, and fencing. Mason Remodeling Co Thousand Oaks provides all of it with one consistent system: written price first, verified crew second, completed work third. Roof replacement in Thousand Oaks runs $8,000 – $20,000, impact window installation $8,000 – $25,000, and vinyl fence installation $3,500 – $9,000, and every one of those projects gets the same written guarantee and the same 365-Day Done Right Promise.
Kitchens, Baths, and Additions
Kitchen and bathroom remodels are our core, but we also handle home additions from $45,000 to $130,000 and ADU construction from $90,000 to $220,000. If it requires permits, framing, plumbing, electrical, and finish work, it’s a general contractor service, and it’s in our wheelhouse.

Exterior Work: Roofs, Driveways, Windows
Roof repairs in Thousand Oaks run $400 – $1,800, and full replacements go up from there. We install GAF, CertainTeed, and Owens Corning roofing systems and work with window brands including CGI, CWS, and ECO Window Systems. One contractor, one written price, one guarantee.

Brands We Service
We install and service CGI impact windows, and we know their product line well enough to recommend the right window for Thousand Oaks heat and sun exposure. CGI is a Florida-based impact brand, and here in Thousand Oaks it’s a common choice for homeowners replacing windows on south-facing walls where UV damage shows up fast.
We also work with CWS and ECO Window Systems on window replacement projects across the Conejo Valley and as a General Contractor - Westlake Village. CWS builds vinyl and aluminum windows that hold up well in Thousand Oaks, and ECO Window Systems offers energy-efficient options that cut down on cooling costs during hot inland summers. Whether you have CGI, CWS, ECO Window Systems, or any other make, we can help.

- Water stains spreading on ceilings or walls: A small stain often means a leak that’s been running for weeks inside the wall or ceiling cavity. In Thousand Oaks, older homes with original roofing or failing shower pans are the most common culprits, and the longer it runs, the more the repair bill climbs.
- Cracks wider than 1/4 inch in foundations or drywall: Hairline cracks are normal settling. Cracks wide enough to fit a nickel usually mean structural movement, and Thousand Oaks hillside lots are more prone to soil movement than flatland tracts. A general contractor can tell you whether it’s cosmetic or structural.
- Doors or windows that stick or won’t latch: When a door starts sticking for no obvious reason, the frame or the foundation may be shifting. This is common in Thousand Oaks homes built before the 1980s, and it’s a warning sign you don’t want to ignore.
- Visible mold or a musty smell that won’t go away: Mold means moisture, and moisture means a leak somewhere you can’t see. In Thousand Oaks, where summer heat and marine layer humidity trade off, trapped moisture in walls creates exactly the right conditions for it to spread.
- Electrical flicker or breakers that trip often: Flickering lights in one room usually mean a loose connection or an overloaded circuit, and both are fire risks. If a remodel is in your future, that’s a problem that needs solving before drywall goes up.
Our Process, Step by Step
- 1
Call and talk to a live person: You’ll reach a live person at (805) 309-3386, 24 hours a day, 7 days a week. No call trees. No voicemail loops. You tell us what’s happening in your home, and we schedule a visit.
- 2
Written estimate on site: Isaac Pruett or one of our project leads walks the job with you, asks the right questions, and produces a written line-item price before anyone picks up a tool. That price doesn’t change unless you change the scope, and you’ll know before you commit.
- 3
Crew verification before arrival: By now you’ll have the name and photo of every crew member coming to your home. On arrival, each one shows a photo ID badge. That’s the Threshold Standard, and it’s mandatory on every Mason Remodeling job.
- 4
Work with daily cleanup: We build, we clean, we protect your floors and surfaces, and we seal the work area at the end of each day. You live in your home during the project, and it should feel like you can.
- 5
Final walkthrough and written guarantee: We walk the finished job with you, point by point, and then hand you a written guarantee with its coverage terms stated plainly: 365 days from the completion date. If anything isn’t right in that window, we return and fix it at no charge.
How Much Does General Contractor Cost in Thousand Oaks?
A typical general contractor project in Thousand Oaks runs anywhere from $800 for a small backsplash installation to $130,000 for a home addition, and most homeowners fall somewhere in the middle. A kitchen remodel lands between $14,000 and $45,000 depending on cabinet choice, countertop material, and whether walls move. A bathroom remodel runs $9,000 to $28,000, while a small bathroom refresh can stay in the $5,000 to $12,000 range. The biggest cost drivers are structural changes, plumbing relocation, and finish material selection, and those are the three things we’ll walk through on your written estimate.
What affects the price: the age of your home, whether permits require structural reviews, the brands you choose for cabinets and surfaces, and how much hidden damage we find when walls open up. How to avoid overpaying: get a written price, not a verbal range, and make sure the written price includes allowances for materials so you’re not hit with upgrade fees later. Our free estimate includes a full scope of work, material allowances, a timeline, and the written price. Call (805) 309-3386 to get yours.
