Interior (Non-Structural) Demo
Interior non-structural demo is the whole-room strip-out before the remodel — cabinets pulled, fixtures out, drywall removed to the studs, baseboards and trim off, interior non-load-bearing partition walls down — handed over as bare framing ready for the next trade, from $1,500 for a single room to $6,000 for a multi-room floor. Cooking gas, hardwired electrical, and in-wall plumbing supply or drain are capped and disconnected by the right licensed trade BEFORE we swing a tool, and we confirm any partition is non-load-bearing against the framing plan before it comes down. Load-bearing walls and structural framing are explicitly outside this trade and route to a licensed Washington L&I contractor — we name the issue on the booking call and come back for the non-structural portion once the structural sign-off lands.

What Does Interior (Non-Structural) Demo Include?
Interior non-structural demo is the whole-room strip-out that hands over bare framing for the next trade — cabinet removal, fixture pull, drywall removal back to the studs, baseboard and trim removal, and selective non-load-bearing partition wall takedown — from $1,500 for a single bonus room to $6,000 for a multi-room main-floor strip. We do not touch load-bearing walls, structural framing, roof or ceiling joists, or anything requiring an engineer's stamp. Pre-1980 homes get tested for asbestos and lead before in-wall, ceiling, or flooring work starts; confirmed asbestos-containing material routes to a Washington State certified abatement contractor before we work in the same room.
Cabinet and Fixture Removal
Base and wall cabinets unscrewed from studs and pulled in whole units where they will not bend through the door. Bathroom fixtures (toilets, vanities, tub or shower surrounds, towel bars) disconnected at the supply stops and pulled. Kitchen sinks lifted out after the disposal and supply lines are disconnected. Salvageable cabinets go to Habitat for Humanity ReStore where you want; everything else to the dump trailer.
Drywall Removal to the Studs
Walls and ceiling drywall scored along the studs and pulled in panel sections to limit dust drift. Insulation pulled where the new layout demands new insulation; left in place where it stays. Vapor barrier integrity noted for the next trade. Drywall dust controlled with HEPA shop vacs and surface-tape protection on adjacent floors and finished surfaces.
Non-Load-Bearing Partition Walls
Interior partitions confirmed non-load-bearing against the framing plan, the home's age and joist orientation, or a structural reference before any cut. Top plate, studs, bottom plate removed cleanly so the next trade has a flat plane. Where load-bearing status is unclear, we stop and route to a licensed Washington L&I contractor for a structural sign-off — and come back for the demo after.
Baseboard, Trim, and Door Casing
Baseboards, door casings, window trim, and crown molding pried off with a flat bar and a backer to protect the drywall edge where drywall is staying. Trim pulled in long sections where reuse is on the table; broken down to bin-size where it is going to the dump.
Utilities Capped by the Right Trade First
Gas lines to a range or wall heater capped by a licensed plumber. Hardwired 120V or 240V circuits to fixtures or appliances disconnected at the panel by an electrician. In-wall plumbing supply or drain capped by a licensed plumber. We coordinate the sequence on the booking call and the right trade arrives first; we follow with the demo once each utility is verified off.
How Interior (Non-Structural) Demo Works
Six sequential steps from the booking-call utility coordination through the cleaned framing handoff — the actual sequence we follow on every Handis interior strip-out.
Booking-Call Coordination of Utility Caps
On the booking call we identify every live utility in the demo zone — gas to a range or wall heater, hardwired 120V or 240V circuits to fixtures or appliances, in-wall plumbing supply or drain — and name which licensed trade caps which line. The right trade arrives first; we follow with the demo once each utility is verified off.
Pre-1980 Asbestos and Lead Test
Homes built before 1980 get tested before any in-wall, ceiling, or flooring tear-out. Common positive surfaces — popcorn ceilings, 9x9 vinyl floor tile and mastic, some drywall joint compound, pipe wrap, lead-paint glaze on older tile. Confirmed asbestos-containing material routes to a Washington State certified abatement contractor before we work in the same room.
Load-Bearing Confirmation Before Any Partition Cut
Any partition wall scheduled for removal is confirmed non-load-bearing against the framing plan, the home age and joist orientation, or a structural reference. Unclear cases stop the demo and route to a licensed Washington L&I contractor for a structural sign-off — we come back for the demo after.
Surface Protection and Dust Control
Drop cloths along the floor of the demo zone and any adjacent hallway, surface tape on finished trim that is staying, plastic sheeting in doorways to isolate the demo from the rest of the home, HEPA shop vacs running through the tear-out and the cleanup. We do not aerosolize the demo into the rest of the house.
Tear-Out in the Right Order
Fixtures and cabinets first (the salvage decisions get made before anything is dusty). Baseboards and trim next. Drywall pulled in panel sections off the studs. Insulation noted and pulled where the new layout demands. Partition walls (already confirmed non-load-bearing) come down last so the studs are not load-pathing the ceiling onto a missing wall mid-job.
Sort, Haul, Sweep
Debris sorted into clean wood, painted wood, drywall, metal, fixtures-for-salvage, and general construction debris streams at the dump trailer. Hauled to a licensed King County or Snohomish County transfer station with a dump weight receipt for the homeowner. Final HEPA vacuum pass on the framing and the floor; the next trade walks into a clean job site.
Interior (Non-Structural) Demo Pricing
Final pricing depends on room count, drywall volume, salvage decisions, disposal weight at the transfer station, and any pre-1980 abatement handoff. Utility-cap trades (plumber, electrician) are billed by those contractors directly. Request a free estimate for an accurate quote.

Why Handis for Interior Non-Structural Demo
Most interior demo problems come from sequence, not the tear-out itself. The gas line to the range is still live when the demo crew arrives. The wall the homeowner wants removed turns out to carry the second-floor joists. The 1962 popcorn ceiling sprays into the air the moment the first scraper hits. After hundreds of interior tear-outs across Seattle, Bellevue, Renton, and Edmonds the pattern is the same — get the sequence right on the booking call, confirm what is structural and what is asbestos before the first tool comes out, and the actual demo is the fast part.
Three checks before the first tool moves
Utilities verified off by the right trade. Asbestos and lead test results in hand on pre-1980 homes. Load-bearing status confirmed on every partition scheduled for removal. The three checks happen before drywall sees a knife. We do not back out of a demo on day one because nobody got the gas line capped or because the popcorn ceiling tested positive on day-of.
Honest scope — non-structural only
We tear out cabinets, fixtures, flooring, drywall on non-load-bearing partitions, trim, baseboards, and small interior partition walls confirmed non-load-bearing. We do NOT remove load-bearing walls, do NOT cut joists or trusses, do NOT modify the load path, and do NOT pull anything that needs an engineer's stamp. Where the line is unclear, we stop and route to a licensed Washington L&I contractor for the structural sign-off — and come back for the non-structural portion after.
Dust isolated room-by-room
Drywall sanding and demo dust is the difference between a one-week remodel and a three-week deep-clean. We tape plastic sheeting in the demo-zone doorways, drop-cloth the floor and any adjacent hallway, run HEPA shop vacs through the tear-out and the cleanup, and pass a final HEPA vacuum on the framing and the floor before we leave. The rest of the house keeps living.
Salvage decisions made before anything gets dusty
Cabinets in good condition, doors, hardware, and fixtures all get a salvage decision on day one. Donation-bound items go to a staging area in the garage or driveway; we drop them at Habitat for Humanity ReStore on the way to the transfer station and the homeowner gets a donation receipt for tax records. Salvage decisions made after a cabinet is bent through a doorway are no longer salvage.
Insured, background-checked, 30-day workmanship guarantee
Every Handis demolition tech carries liability insurance and has cleared a background screening. The 30-day workmanship guarantee covers what we did to the site — a finished surface adjacent to the demo we should have protected, a doorway scuff from a cabinet pull-out, a debris-pile dent in the next room's drywall. Demolition damage to the items being removed (the cabinets, the tile, the drywall) is by design — those are the demo target.
Estimate
Tell us the rooms (single bonus, bath, master suite, whole-floor), the rough square footage, the home year (pre-1980 triggers asbestos and lead testing), every live utility in the demo zone (gas range, hardwired electrical, in-wall plumbing), and any salvage you want kept aside. We will sequence the trades and quote the demo.
Customer Reviews
Interior non-structural demo reviews from real Handis customers.
Full main-floor strip before a remodel. Tech walked the house Tuesday, identified that the gas line to the range and the wall between the dining room and kitchen needed sign-offs first — gas cap from a plumber and load-bearing confirmation from the GC. Both happened Wednesday and Thursday. Crew started Friday, finished the strip the following Wednesday. Cabinets donated to ReStore at my request. Framing handed over clean.
1955 split-level master suite. Popcorn ceiling in the bedroom tested positive for asbestos on day one. Crew stopped, gave me a name for abatement, came back the next week after the ceiling was cleared. Then tore out the bath (toilet, vanity, tub, tile) and the bedroom drywall in two days. Saved me from an illegal mistake and a much bigger bill.
Single bonus room over the garage going from carpet+cabinets to a home office. Quick demo — cabinets out, baseboards and trim off, drywall ceiling stayed but the kneewall partition came down (non-load-bearing, confirmed against the original plans). One day on-site, framing clean, ready for the electrician.
Tricky partition wall between the kitchen and the dining room. I assumed it was load-bearing but the floor plan said otherwise. Handis tech checked the joist direction in the basement first, confirmed parallel under no header line, then took it down clean. Top plate, studs, bottom plate gone in two hours. The kitchen now opens to the dining room exactly like we wanted.
1960s Ravenna bungalow, both bathrooms and the kitchen at once. Crew sequenced it with the plumber and electrician (their referrals) so utilities were capped Monday morning and the demo ran Tuesday through Friday. Asbestos test on the kitchen vinyl came back negative; lead test on the bath tile came back positive on the glaze, so we paused while the RRP contractor took the tile out. Came back for the drywall after. Bare framing by the following Tuesday.
