The Old Floor Removal and Disposal SOP

Purpose

Take the old floor out without exposing the crew, the customer or the next trade to what is in it, and leave a substrate the install crew can work on the same day. Tear-out is the part of a flooring job most likely to put asbestos fibers, crystalline silica or lead dust into a house, and it is also the part most often handed to the newest person on the crew. This SOP makes the stop decision a defined step with a named owner, instead of something a helper decides with a scraper in their hand.

Scope

Covers removal of carpet and cushion, wood, laminate and resilient floors, ceramic and stone tile, their fasteners, strip and residue, down to a clean substrate, and disposal of the debris. Does not cover abatement of material confirmed to contain asbestos, which goes to a contractor licensed for it where your state requires one; lead-safe practices in pre-1978 homes, which run alongside this SOP under The Lead-Safe Floor Work SOP; or protecting the rest of the house, which is The Flooring Job Site Protection SOP and must be in place before step 3.

Roles and the handoffs

Only the crew lead may restart work in a room where a stop was called, and only with the office's written note of what cleared it.

The procedure

1. Read the file before anyone lifts a tool. The crew lead checks the assessment sheet for every room against what will be removed: each layer named, and for every resilient layer or black adhesive that could have been installed in 1980 or earlier or is of unknown age (OSHA 29 CFR 1926.1101 presumes such resilient flooring is asbestos-containing until shown otherwise), a lab result showing none detected for that specific layer, or a written decision not to disturb it. Acceptance: one result per suspect layer; a tile and its adhesive are two layers and need two results. Wrong looks like a single result for "the floor" covering a tile and its mastic. Stop rule: any suspect layer without its own result is not disturbed, and that room waits. Hazard: none at this step; it is the step that prevents the hazard.

2. Confirm the house is protected and the fixtures are out. Check that the protection SOP is complete: HVAC off or returns sealed in the work zone, dust walls up, path covered. Appliances and toilets are out, with gas and water disconnected by the licensed trade where your state or locality licenses that work. Acceptance: work zone sealed, every fixture on the sheet out of the room, every disconnected line capped. Wrong looks like a supply line open to the room or a gas stub uncapped. Stop rule: no tear-out with an open line; call the trade back. Hazard: never move a gas appliance or reach behind one yourself, and treat an uncapped gas stub as a leak until the trade has capped and tested it.

3. Open one inspection point and compare it to the sheet. At an edge, a register or a closet, take the top layer up a hand's width and look at every layer beneath. Acceptance: the layers you see match the sheet exactly. Wrong looks like a layer nobody listed, most often old tile or black adhesive under carpet or under a floating floor. Stop rule: an unlisted resilient layer or dark adhesive stops work in that room under Job Site Asbestos Discovery Stop Work Protocol: leave it as it is, do not sweep or dry-vacuum it, close the room, and call the crew lead. Hazard: open the point with hand tools only, never a saw or grinder, so a surprise layer is not cut into.

4. Remove carpet, cushion, strip and staples. Cut the carpet into strips about 3 feet wide, roll them, then roll the cushion, pull staples and pry tack strip from the wall side. Acceptance: substrate bare to the walls, no staples left standing, tack strip out and bagged. Wrong looks like black adhesive or old tile revealed under the cushion; that is the step 3 stop rule again, because the inspection point only showed you one corner. Hazard: tack strip pins and carpet knives cause most removal injuries, so wear cut-resistant gloves and knee pads, cut away from your body with the hook blade, and bundle strip pins-in before it is carried.

5. Remove wood, laminate and floating floors. Floating floors come up row by row from the last row installed. Nail-down floors are cut into sections with a circular saw set to the board's thickness, then pried up with a flat bar. Glue-down wood comes up with a long-handled scraper or a powered stripper. Acceptance: no flooring left, fasteners out or set flush. Wrong looks like the saw meeting something below the subfloor surface. Stop rule: confirm there is no radiant tube, duct or wire under the cut line from below before cutting, and stop the saw on any unexpected resistance. Hazard: set the saw depth before every cut, keep the guard working, and pull nails rather than walking on them.

6. Remove ceramic and stone tile with dust controlled at the tool. Break tile out with a hammer and chisel or a powered chipping tool, with water delivered to the cut or a shroud with dust extraction, and the respirator the OSHA silica construction standard's (29 CFR 1926.1153) Table 1 entry for that tool requires for the duration and the space. See Silica Dust in Flooring Work for the controls. Acceptance: no visible dust plume leaving the work point, tile out to the substrate. Wrong looks like a haze in the room or dust on the far side of the dust wall. Stop rule: stop and fix the control before continuing. Hazard: crystalline silica from tile, mortar and concrete is an inhalation hazard, so dry sweeping and compressed air are not cleanup methods; flying shards also need eye protection and hearing protection for powered tools.

7. Clear residue and fasteners down to a workable substrate. Scrape thinset ridges and adhesive that the file confirms is not asbestos-containing, pull or set every nail, and fill what the install method needs filled. Acceptance: no residue ridge or fastener head you can catch with a scraper blade, substrate ready for its prep per Subfloor Assessment + Repair Reference. Wrong looks like a crew member reaching for a grinder on black adhesive with no result in the file. Stop rule: black adhesive is never ground, sanded or bead-blasted without a none-detected result. Hazard: grinding concrete to remove residue is a silica task with its own Table 1 controls.

8. Sort the debris and dispose of it by your local rules. Keep carpet and cushion apart where a recycler takes them, wood apart where it is accepted, tile and concrete as rubble, and anything that tested positive out of your containers entirely; that material leaves only with the abatement contractor under the rules that govern it (state and local rules, and the EPA asbestos NESHAP where it reaches the job). Acceptance: debris in the container booked for it, container covered, path swept. Wrong looks like a bag of mystery residue thrown in the dumpster. Stop rule: anything you cannot name goes to the crew lead, not the container. Hazard: carry heavy rubble in buckets you can lift, not overfilled bags, and keep the load-out path free of strip and nails.

9. Close out the room and hand it to the install crew. HEPA-vacuum the substrate and the zone, photograph each room's bare floor, and write on the sheet what was found and what was removed. Acceptance: photos taken, sheet updated, no debris left in the work zone. Wrong looks like the install crew learning about a patched area from the floor rather than the sheet. Stop rule: a substrate you would not install on is written up as such, with a photo, and goes to the owner for a prep decision. Hazard: none.

The record this produces

For each room: the layers found at the inspection point and after removal, any stop called with its time, who was called and what cleared it, the test result reference for every suspect layer, the disposal route for each debris type, and before-and-after photos. The office keeps it with the job. It is read by the install crew the next morning, by the owner when a stop changes the price, and by anyone answering a later question about what was in that floor and where it went.

Worked pass: carpet out of a 1971 living room

The file: home built 1971, living room and hall carpet to come out for glue-down luxury vinyl tile on the slab. The assessment sheet listed carpet over cushion over concrete, seen at the closet edge. No resilient layer listed, so no samples taken.

Step 1 passed on what the sheet said. Step 2 passed: HVAC off, the hall return sealed, a dust wall at the kitchen.

Step 3 passed. The inspection point at the closet showed carpet, cushion and bare concrete, matching the sheet.

Step 4 failed its acceptance. With the cushion rolled back, a band of black adhesive about 6 feet by 10 feet showed in front of the fireplace, the outline of a tile floor taken up decades ago. The stop rule triggered. The crew left the adhesive and the tack strip over it in place, rolled the carpet back over the band rather than dragging it, did no sweeping, closed the room and called the crew lead, who called the office within the hour. The carpet over the rest of the room was cut free a foot outside the band and removed, leaving a cut piece lying over it; the hall went ahead because its bare slab matched the sheet.

The office arranged a sample of the adhesive. The result came back positive. The owner wrote the customer a revised scope with two paths, removal by an abatement contractor or installing over it with an approach the vinyl maker accepts, and the customer chose. The diagnosis side of that call is in The Black Mastic Under the Old Carpet.

Steps 5 and 6 did not apply, since there was no wood or tile. Step 7 ran in the hall only: slab scraped clean, tack strip nail holes left flush; the living room was held at step 4 until the decision. Step 8: carpet and cushion went to a recycler, tack strip bagged and binned, nothing from the fireplace band touched the container. Step 9: photos of both rooms, the stop and its time on the sheet.

The sheet now says what it should have said, and the next estimator on that street reads it.
