Service 1

General Contractor

Hiring a General Contractor isn’t just “finding someone with a truck.” It’s picking the person (and the system) who’s going to control your budget, your schedule, your inspections, and—let’s be honest—your stress level.  


In Petaluma CA, that matters because homes here are a mix: older Victorians near downtown, ranch-style houses out toward East Petaluma, and plenty of properties that have been remodeled in layers over decades. Add winter rains, damp mornings, and the reality of local permitting, and you don’t want guesses—you want a plan.  


Design Build Specialists has 40 years of Marin & Sonoma experience, and we run projects with a design/build process built for efficiency. Our Design Build Clarity Plan™ is where we earn our keep: we map the existing conditions, create 3D conceptual drawings, work through zoning and permit realities, and lock in a realistic budget and timeline before you commit. That means fewer surprises, fewer “we didn’t know that was there” moments, and way less back-and-forth between disconnected designers and builders.  


This pairs naturally with Whole House Remodeling when you want one team coordinating everything instead of juggling multiple trades and opinions. If you’re looking for a Remodeling Contractor who keeps costs predictable, start here.

Kitchen Remodeling

Kitchen Remodeling is where good intentions go to die if the planning is sloppy. It’s not just cabinets and countertops—it’s workflow, lighting, ventilation, electrical loads, plumbing locations, and the daily reality of living without a functioning kitchen.  


In Petaluma CA, we see a lot of kitchens that were designed for a different era—tight layouts, not enough circuits for modern appliances, and windows/doors placed in ways that fight the floorplan. And if your home is older (think areas near Washington St. or the historic district), you can also run into uneven floors, out-of-square walls, and surprises behind plaster.  


Design Build Specialists handles kitchen remodeling as a true design/build project. We start with the Design Build Clarity Plan™ so you can see the new kitchen in 3D, make decisions before demolition, and get a budget and timeline that match the real scope. As experienced kitchen remodelers, we focus on the details that make the room feel right—clearances, storage, lighting layers, and finishes that hold up to real life.  


If you’re comparing a remodeler versus a full remodeling firm, this is where the difference shows: we coordinate design, permitting, and construction under one roof.  Kitchen projects also pair well with Custom Cabinets, since the right cabinet plan is what makes the whole kitchen function.

Bathroom Remodeling

Bathroom Remodeling sounds simple until you open the walls. Bathrooms are small, but they’re packed with the stuff that can ruin a house fast—water lines, drains, waterproofing, ventilation, and tile work that has to be done right the first time.  


In Petaluma CA, the damp winter season and cool mornings make proper ventilation and moisture control a big deal. In older homes, you may also be dealing with outdated plumbing, undersized fans, or previous “quick fixes” that don’t meet today’s expectations (or sometimes even today’s code).  


Design Build Specialists can take you from a low-cost facelift to a full gut remodel—tub-to-shower conversions, shower-to-tub transformations, cabinet refacing or full cabinet replacement, fixture upgrades, new tile, and paint. Want the spa vibe? We can do that too. The point is: we help you choose the level that fits your budget and timeline without guessing. Our Design Build Clarity Plan™ lets you see options in 3D, settle on layouts and materials before demo, and avoid the classic remodel stress of “How much is this going to cost now?” 


Bathroom remodeling pairs naturally with Countertops when you’re upgrading vanities and want a cohesive, durable finish across the home.

Whole House Remodeling

Whole House Remodeling is where people either save time and money—or burn both—depending on who’s running the show. When you’re moving walls, reworking layouts, upgrading systems, and touching multiple rooms, the domino effect is real. One late decision can stall five trades.  


Petaluma CA homes often come with quirks: additions done decades ago, mixed materials, sloped floors, and layouts that don’t match how families live now. And if you’re anywhere near the older neighborhoods, you may be balancing character details with modern performance—insulation, windows, electrical capacity, and clean mechanical runs.  


Design Build Specialists is a remodeling contractor with deep Marin & Sonoma experience—from small homes to hillside properties. We don’t start swinging hammers until we do the Design Build Clarity Plan™. That’s where we confirm feasibility, work through zoning/permitting realities, create 3D conceptual drawings you can actually understand, and build a budget and timeline you can plan around. It’s the difference between “hope it works out” and “we know what we’re doing next week.”  


If you want predictable costs and fewer headaches, this is the lane where design/build shines. Whole-house projects pair well with Room Additions when the remodel reveals you’re better off adding square footage instead of forcing a cramped layout.

ADU Construction

ADU Construction is not a “backyard shed with a kitchenette.” It’s a real dwelling with real rules—setbacks, utility connections, fire separation, access, drainage, and inspections that don’t care how nice the finishes are if the bones aren’t right.  


In Petaluma CA, ADU planning has to match the lot you actually have, not the one in your head. Between local zoning requirements, existing structures, and the realities of tying into older utilities, the design has to be practical from day one. Winter rains also mean you need smart water management and durable exterior details.  


Design Build Specialists brings sustainable building experience and a design/build process that reduces expensive rework. We use the Design Build Clarity Plan™ to confirm what’s buildable, produce 3D drawings, and create a realistic cost-to-build picture before you commit. That way, you’re not paying for plans that look great but blow up your budget once construction starts.  


If you’re looking for a remodeling firm that can keep the ADU on track—design, permits, and build—we keep it in one coordinated lane. ADU Construction pairs well with Outdoor Living Spaces, since patios, pathways, and yard flow often need to be rethought once the ADU footprint is set.

Custom Cabinets

Custom Cabinets are where a room either feels dialed-in—or like you settled. Stock boxes can work sometimes, but when you’re trying to maximize storage, fix awkward corners, or match an older home’s character, custom is often the cleanest solution.  


In Petaluma CA, we see plenty of homes where walls aren’t perfectly square and floors aren’t perfectly level—especially in older neighborhoods. That’s when off-the-shelf cabinets can leave gaps, weird filler strips, or wasted space that you notice every single day.  


Design Build Specialists has been building and sourcing cabinets for decades. We have access to top cabinet manufacturers and resources, and we routinely design and install custom cabinets for kitchens, bathrooms, laundry rooms, mudrooms—anywhere you need storage that actually fits your life. Because we’re a design/build team, we coordinate cabinet layouts with electrical, plumbing, lighting, and appliance specs so you’re not stuck redoing work later.  


This is also where our process saves headaches: decisions get made in the Design Build Clarity Plan™ phase, not when your kitchen is torn apart and you’re under pressure.  Custom Cabinets pair naturally with Kitchen Remodeling, since the cabinet plan is the backbone of the whole layout and budget.

Cabinet Refacing

Cabinet Refacing is the middle path when your cabinet boxes are solid but the look is dated—or you want a change without tearing your house apart. The reality is, a full cabinet replacement isn’t always necessary, and it’s not always the smartest use of money.  


In Petaluma CA, a lot of homes have older cabinetry that’s structurally fine but visually stuck in another decade. If your layout works and the boxes are in good shape, refacing can get you a big visual upgrade with less disruption—helpful when you’re trying to keep life moving during the project.  


Design Build Specialists offers full-spectrum refacing solutions: new doors and drawer fronts, updated hardware, improved storage features, and finish options that fit the rest of your remodel. Because we’ve carried cabinet products and built custom solutions for decades, we can guide you away from cheap shortcuts and toward materials that hold up to real daily use.  


We also plan refacing the right way—measuring, aligning, and making sure the finished look is clean, not “close enough.” If you’re working with a remodeler who rushes this step, you’ll see it every time you open a door. Cabinet Refacing pairs well with Countertops—many homeowners refinish the cabinets and upgrade the tops at the same time for a cohesive result.

Custom Countertops

Countertops look simple until you’re the one living with bad seams, awkward overhangs, or a surface that stains every time someone makes coffee. This is one of those details that gets touched every day—so it needs to be chosen and installed with care.  


In Petaluma CA, we often run into older kitchens and baths where cabinets have shifted over time, walls aren’t straight, or the original layout wasn’t built for today’s larger sinks and appliances. That means templating and installation have to be precise, and the material choice has to match how you actually use the space.  


Design Build Specialists is a preferred vendor for major countertop products, and we routinely build custom countertop solutions in kitchens, bathrooms, and beyond. We coordinate countertops with cabinet design, backsplash details, sink/faucet selections, and appliance specs so you don’t get stuck with last-minute compromises. 


Our design/build approach helps you make decisions early—during the Design Build Clarity Plan™—so the budget and schedule stay predictable. No scrambling because a material is backordered or a detail was missed. Countertops pair naturally with Bathroom Remodeling, especially when you’re upgrading vanities and want durable, easy-to-clean surfaces that still look sharp years later.

Outdoor Living Spaces

Outdoor Living Spaces are where you feel the payoff of your remodel—morning coffee outside, family dinners, a spot to watch the fog roll in, or a place to warm up when Petaluma evenings cool off.  


The reality is, outdoor projects can go sideways fast if they’re treated like “just a deck.” Drainage, grading, footings, sun exposure, wind, and material choices all matter—especially with our winter rains and the wear-and-tear that comes with real weather. And depending on where you are in Petaluma CA, you may be dealing with tight side yards, older fencing, or a yard that wasn’t designed for how you want to use it now.  


Design Build Specialists brings the same design/build discipline outside as we do inside: we plan it, we visualize it, and we build it to last. That includes layout, access, lighting, surfaces, and the transitions between indoors and outdoors so it feels intentional—not like an afterthought.  If you want a space that’s comfortable, functional, and built without drama, we’ll walk you through options that match your budget and timeline.  


Outdoor Living Spaces pair well with Room Additions, since many additions work best when the exterior flow—patios, paths, and yard use—is redesigned at the same time.

Room Additions

Room Additions are the fastest way to get the space you need—if they’re planned correctly. The reality is, you’re tying new structure into old structure. That means foundations, framing, roofing tie-ins, insulation, windows, mechanical systems, and finishes all have to line up so the addition doesn’t look (or feel) like an afterthought.  


In Petaluma CA, additions also have to respect the lot and the rules—setbacks, height limits, floor area ratios, and permit requirements. And because many homes here have been modified over time, you want someone who can spot conflicts early: old electrical panels, undersized HVAC, or drainage that needs attention before you expand.  


Design Build Specialists approaches additions with the Design Build Clarity Plan™ so you can see the new space in 3D, confirm feasibility, and lock in a realistic budget and timeline before construction starts. That’s how we avoid the classic addition nightmare: half-built spaces, constant changes, and costs climbing every week. Whether you’re adding a bedroom, expanding a living room, or creating a new primary suite, we keep the process organized and the site respectful—show up, protect the home, and clean up.  


Room Additions pair naturally with Whole House Remodeling because once you add square footage, it often makes sense to update layouts, finishes, and systems for the rest of the house at the same time.

Frequently Asked Questions

  • How much does remodeling cost in Marin County?

    Remodeling costs in Marin are typically higher than the national average due to labor rates, permitting requirements, hillside construction challenges, and the age of many homes. Kitchen remodels often start in the mid–high six figures depending on scope. Bathrooms vary based on plumbing and finish level. Whole-house remodels and ADUs require detailed feasibility review. That’s why we use our Design Build Clarity Plan™ — so you understand realistic costs before construction begins.
  • How do you prevent cost overruns and change orders?

    Most overruns happen because projects are under-designed before construction starts. Our Design Build Clarity Plan™ includes 3D design, detailed scope definition, material selections, and permit feasibility review before demolition. Pricing is based on real decisions — not allowances and guesses. That dramatically reduces surprises and budget creep.
  • How long will my remodel take?

    Timelines depend on scope and permitting. Bathroom remodels typically take several weeks. Kitchens often run 8–12+ weeks. Whole-house remodels, additions, and ADUs can take several months including permits. We provide a clear construction schedule before work begins and tightly manage trades to keep momentum strong.
  • Do I need permits for my project in Marin?

    In most cases, yes. Marin municipalities like San Rafael, Mill Valley, Novato, and Tiburon have strict permitting, zoning, and inspection requirements. Even smaller projects can trigger structural, plumbing, or electrical review. We verify zoning and permit requirements early to prevent expensive redesigns later.
  • Can we live in our home during construction?

    Often yes, depending on the project scope. Kitchen remodels require temporary cooking arrangements. Bathroom remodels require coordinated water shut-offs. Larger whole-house remodels or additions may require temporary relocation. We discuss livability during planning so there are no surprises.
  • What makes remodeling in Marin different?

    Marin homes often include older framing, outdated plumbing and wiring, hillside foundations, moisture exposure from coastal fog, and tight access streets. Add strict zoning and floor-area limits, and experience becomes critical. We build with these realities in mind from the start.
  • When should we contact a contractor?

    Earlier than most homeowners expect. Designing a project without cost alignment is where budgets break down. Our design/build process aligns feasibility, design, and investment from the beginning — so you don’t fall in love with something that can’t be built within your target range.
  • Do you handle both design and construction?

    Yes. We are a true design/build firm. You work with one integrated team from concept through completion. No finger-pointing between architect and contractor. One plan, one contract, one accountable team.
  • What types of projects do you specialize in?

    We specialize in kitchen remodeling, bathroom remodeling, whole-house remodeling, room additions, ADU construction, custom cabinetry, cabinet refacing, countertops, and outdoor living spaces. If the project requires tight coordination and thoughtful planning, we’re built for it.
  • What happens during the first consultation?

    The first meeting is focused on clarity. We discuss your goals, timeline, and investment range, and review zoning or structural realities that could affect the project. If it’s a good fit, we walk you through the Design Build Clarity Plan™ so you understand the exact next steps before committing to construction.
