Controlled Interior Demolition That Preserves What Stays and Removes What Goes
Every renovation starts with removal. Before your contractor can frame a new wall, install fresh flooring, or reconfigure a layout, the existing materials have to come out cleanly and without damaging the structure around them. That's the job Sonoma Demolition's interior demolition crews are built for. The team serves homeowners, general contractors, and property managers throughout the North Bay region, handling everything from single-room selective tear-outs to full gut renovations that strip a building back to its frame. Containment barriers, dust suppression, and daily debris removal are standard on every project. The crew is licensed under both a C21 demolition classification and a B general contractor classification, with OSHA safety certifications that govern how they work in occupied and adjacent-occupied buildings. Your renovation timeline starts the day the interior demo is finished, so getting it done right and on schedule matters.
What Interior Demolition Covers, from Selective Removal to Full Gut-Outs
Interior demolition isn't one task. The scope changes based on what's being removed, what's staying, and how the surrounding structure needs to be protected during the process. Sonoma Demolition breaks interior demo into defined sub-services so every aspect of the project is accounted for: wall removal, flooring extraction, ceiling demo, drywall stripping, fixture and fitting takeout, debris management, and dedicated bathroom and kitchen demolition. Each sub-service follows its own protocols for containment, material handling, and structural preservation, and sits within the full scope of work the crew offers.
Wall Removal
Walls come out for two reasons: to open up a floor plan or to replace what's behind them. Either way, the approach depends on whether the wall is load-bearing or non-structural. Sonoma Demolition identifies the wall type before any work begins, installs temporary shoring on load-bearing walls where required, and removes the wall assembly including framing, drywall, insulation, and any embedded wiring or plumbing. The opening is left clean and structurally sound for your framing contractor to pick up, and where the structure itself has to go, the whole building can come down instead.
Flooring Removal
Hardwood, tile, vinyl, laminate, carpet, and concrete overlays all require different extraction methods to protect the subfloor underneath. Sonoma Demolition removes all flooring types down to the substrate, including adhesive residue and underlayment, so the surface is ready for your installer without additional prep work. On projects where the subfloor needs replacement, common in the older bungalows around Santa Rosa, the crew pulls that layer too and leaves the joist or slab surface exposed and clean.
Ceiling Demolition
Dropped ceilings, textured plaster, drywall ceilings, and acoustic tile systems are all removed as part of Sonoma Demolition's ceiling demo services. The crew works overhead with containment below to keep dust and debris from spreading through the rest of the building. Electrical fixtures, HVAC registers, and sprinkler heads are disconnected or protected before ceiling materials come down, which matters most on tenant spaces and office floors with grid systems overhead.
Drywall Removal
Stripping drywall exposes the framing, wiring, plumbing, and insulation behind it, which is exactly what your renovation contractor needs to see before the rebuild begins. Sonoma Demolition removes drywall panels, plaster, and lath in sections, controlling dust with plastic barriers and negative air pressure where conditions require it. Fasteners are pulled or cut flush so the exposed studs are ready for new board, on jobs from the Victorians and ranchers around Petaluma outward across the North Bay.
Fixture Removal
Cabinets, countertops, sinks, toilets, bathtubs, vanities, built-in shelving, and light fixtures all get removed as part of interior demolition. Sonoma Demolition disconnects plumbing and electrical feeds safely before extracting each fixture, capping lines where needed to prevent leaks or hazards. Fixtures are either disposed of or staged for the owner to keep, a common request on the mid-century and custom homes throughout Marin County. The spaces left behind are clean, capped, and ready for new installations.
Interior Debris
Interior demolition generates a high volume of mixed material: broken drywall, splintered framing, old insulation, tile fragments, adhesive-coated subfloor, and general construction waste. Sonoma Demolition handles all debris removal as part of the interior demo scope. Materials are bagged, carted, and loaded into containers or trucks throughout the workday on sites across every county we cover, so the job stays organized and safe. The space is broom-swept before the crew calls the job complete.
Bathroom Demolition
Bathrooms pack a lot of material into a small footprint: tile on walls and floors, a vanity, toilet, tub or shower enclosure, mirrors, medicine cabinets, and often layers of flooring stacked over decades. Sonoma Demolition strips bathrooms down to the framing, disconnecting all plumbing and removing every surface, fixture, and fitting. Waterproofing membranes and backer board come out too, and the same water-and-concrete know-how applies when an old pool has to come out of the yard.
Kitchen
Demolition
Kitchens are the most material-dense rooms in most homes: upper and lower cabinets, countertops, backsplash tile, flooring, appliance hookups, soffits, and sometimes load-bearing modifications from previous remodels. Sonoma Demolition performs full kitchen gut-outs, removing every installed element down to the bare walls and subfloor. Gas lines, water supply, and drain connections are properly capped by a crew holding both a C21 and a B license. The cleared kitchen is ready for your designer's or GC's layout to begin without any remnants of the old configuration in the way.
