Fast, Reliable General Contractor Across Santa Rosa
Most Santa Rosa homeowners come to us with one of two situations. Either they’ve lived with a dated kitchen and bath long enough and are finally ready to do the whole thing right, or they’re half-parked in the driveway of an unfinished project that a previous contractor walked away from. Both start the same way here: we scope the work, put every price in writing, and tell you exactly who is coming before anyone rings your bell. Our crews serve Santa Rosa from the Bennett Valley foothills to the older neighborhoods off Pacific Avenue. Call (803) 680-2547 and we’ll come out, measure, and hand you a line-item written estimate. No vague verbal numbers, no showroom runaround.
Why Mason Remodeling Is Santa Rosa’s Preferred General Contractor Company
Call any contractor in Santa Rosa and the first thing you want to know is who shows up at your door. We name our technicians before they arrive. You get a name, a photo, and a uniformed professional who shows a photo ID badge on the doorstep. That is the Threshold Standard, and it’s how we’ve operated since 2004 as part of the Threshold Group family of home-service companies. Every location is independently owned, and every one follows the same verification process.
What keeps Santa Rosa customers calling us back is the written guarantee we hand over before work starts, not after. Every project is covered in writing from the completion date. If a repair or installation fails within 365 days, we come back and make it right at no charge. Our 365-Day Done Right Promise applies across general contracting, bathroom remodeling, and whole-home remodels. If something fails outside that window, we still do a free second visit because a failed repair is on us until it’s fixed.

Styles & brands we work with
Licensed General Contractor in Santa Rosa
A Licensed General Contractor in Santa Rosa handles structural, load-bearing, and multi-trade work that a handyman legally cannot. That means room additions, ADUs, garage conversions, whole-home remodels, and any job where you’re moving or removing walls. Santa Rosa sits in a high seismic hazard zone, so structural changes here almost always require engineered shear-wall and hold-down details. The city’s Building Division routes most residential additions and ADUs through plan check and inspection sign-off, and that plan review timeline is part of your project calendar whether you planned for it or not. Kitchen remodel pricing in Santa Rosa typically runs $14,000 – $45,000; a home addition lands between $45,000 and $130,000 depending on square footage and foundation work.
Permits, Plan Check, and Inspections
We pull permits on every job that requires them. That includes structural changes, electrical, plumbing, and any gas line work. Skipping permits on a load-bearing change to save two weeks is how Santa Rosa homeowners end up with a failed inspection sign-off, a tear-out order, and a re-inspection fee that doubles the cost of having walked it through plan check the right way the first time. Mason Remodeling prices permit fees, plan check, and inspection coordination into the written estimate before work begins.
Change Orders and Why We Price Them in Advance
The most common change order on a Santa Rosa remodel is dry rot near original 1960s plumbing. We saw it in Bennett Valley or the Montgomery Village area: open the subfloor, find rotted joists, and suddenly the tub-to-shower conversion needs sistered joists before the rough-in can pass sign-off. We write allowances into the contract for structural repairs before demo day. When we do hit something unexpected, you get a written change order with a line-item price. Nothing gets added to your invoice verbally.
Residential General Contractor in Santa Rosa
A Residential General Contractor in Santa Rosa works on the home you live in, not commercial sites. That means we protect floors, seal off dust, and schedule around your family. Most of the homes we work on in the Rincon Valley and Bennett Valley areas were built between the 1950s and 1980s. Galvanized supply lines are common, framing is often undersized by current seismic code, and subfloors have usually been wet at least once. We factor all of that into the scope before we ever cut drywall.
Kitchen and Bath Scoping
A full bath remodel in Santa Rosa runs $9,000 – $28,000. A tub-to-shower conversion is $3,500 – $10,000. Countertop installation comes in between $2,000 and $6,500. What moves a bath job to the top of that range is the same thing that moves a kitchen job: opening a wall and finding cast iron drain lines, a rotted floor system, or wiring that’s no longer up to code. We price the visible scope and write explicit allowances for the hidden stuff. You see both numbers in your written estimate.
Additions, ADUs, and Garage Conversions
Santa Rosa allows ADUs on most single-family lots, but the construction cost is real: $90,000 – $220,000 depending on size, foundation, and utility connections. Garage conversions are less expensive at $30,000 – $80,000, but they still trigger seismic requirements because you’re converting a non-conditioned space into living area. That means shear-wall engineering, insulation, and a lot of electrical. We walk you through what the Building Division will actually ask for before we quote it, so the number you sign is the number you build to.
Trusted Brands We Service in Santa Rosa
Santa Rosa homeowners don’t need to chase down a dozen different suppliers. We hold specification-grade partnerships with KraftMaid and Wellborn cabinetry, Cambria, Silestone, and Caesarstone surfaces, and Kohler, Moen, Toto, and Grohe fixtures. That means one point of contact for the entire job and one person responsible for lead times. We keep current on local stock availability so a kitchen order doesn’t sit in permit limbo waiting on cabinetry. You’ll find the same approach with modern prefab systems from Abodu and Dvele when an ADU is the better path than a site-built addition.
Common General Contractor Problems We See in Santa Rosa Homes
- Old galvanized supply lines behind the wall. Homes built before the 1970s in neighborhoods like the Junior College and Montgomery Village areas often still have original galvanized pipe. It fails mid-remodel, usually when it’s disturbed, so we identify it during scoping and allow for replacement before it becomes an emergency.
- Seismic retrofit requirements on structural work. Santa Rosa’s Building Division requires engineered hold-downs and shear-wall details on load-bearing changes. This isn’t optional, and it’s not a city being difficult. It’s the same requirement that would have protected homes in the 2017 Tubbs Fire zone and every earthquake since.
- Permit sequencing delays that no one budgeted for. Plan check in Santa Rosa can take weeks, and cabinet lead times from KraftMaid and Cambria can stretch just as long. A realistic calendar sequences these in parallel, so the job doesn’t stall between rough-in and finish.
- Verbal estimates that grow on the final bill. It’s the most common call we get after someone has paid another contractor a deposit. The written price is the only price. Our contract includes allowances for hidden conditions and nothing gets charged without a signed change order.

FAQs About General Contractor in Santa Rosa
Yes, for nearly any kitchen or bath remodel in Santa Rosa that moves plumbing, electrical, or walls. Santa Rosa’s Building Division requires permits for those trades, and inspections happen at rough-in and final. Non-structural cosmetic updates, like replacing cabinet fronts or swapping a faucet, generally don’t need one. When we quote your project, the permit fee and plan-check cost are already in the written estimate. Call (803) 680-2547 if you want to know whether a specific change triggers a permit.
In Santa Rosa, the three most common price changers are dry rot under old flooring, galvanized plumbing that has to be replaced, and seismic structural corrections the city requires once walls are open. That’s why our contract includes written allowances for hidden conditions. You see the allowance amount before demo starts. If we don’t use it, you don’t pay it. For an exact breakdown on your project, call (803) 680-2547.
A straightforward bath remodel in Santa Rosa takes 3 to 6 weeks. A full kitchen is usually 6 to 12 weeks. An ADU or home addition can run 4 to 8 months because plan check and the inspection sequence alone take weeks. What slows projects down here is not the work itself, it’s waiting on plan review, waiting on cabinet lead times, and coordinating inspections. We sequence those in parallel so your project doesn’t stop between phases.
A draw schedule is a written payment plan tied to project milestones, not dates. We use them on every Santa Rosa remodel above a certain size: a deposit to secure materials, a draw at rough-in inspection passing, a draw at drywall or cabinet installation, and the final draw at completion. This protects you because you never pay ahead of the work the city has already signed off on. Call (803) 680-2547 and we’ll show you a sample draw schedule for your specific project.
Yes, most Santa Rosa single-family lots are eligible for an ADU or a garage conversion under current city policy. The construction costs differ significantly: a garage conversion runs $30,000 – $80,000, while a new detached ADU is $90,000 – $220,000. Both trigger seismic requirements because a garage is a non-conditioned space being turned into living area. We handle the engineering, permits, and construction as one scope. Call (803) 680-2547 for a free estimate on your property.
