Demolition in Redding, CA

What is the first thing that happens on a bathroom tear-out morning?

The water gets shut off before anything else happens. A bathroom has more plumbing packed into a small space than any other room in a house, and one stuck valve can turn a four hour job into a flooded hallway. The crew finds the stop valves under the sink and behind the toilet, closes them, opens a tap to drain the line, and checks that the flow has actually quit. If a stop valve will not turn, or turns and still weeps, the work moves to the main shutoff for the house and the household goes without water until the new valves are in.

Power comes off next. The circuit for the bathroom fan, the outlet by the sink and the light is switched off at the panel and tested at the fixture, because a breaker label written thirty years ago is not proof of anything. Houses in Redding that were remodeled in pieces often have a bathroom light fed from the hallway circuit, so a tester goes on every wire before a hand goes near it.

How does the room get protected before the demolition starts?

Most bathrooms open onto a hallway, and a hallway carries dust to every bedroom. Plastic goes over the doorway, floors on the path to the dumpster are covered with paper and hardboard, and any heating or cooling register in the room is blocked. The tub or shower drain gets stuffed with a rag so no grout or tile chip can fall into the line. The toilet flange gets the same treatment, a rag pushed into the opening and a bucket over the top so a chunk of debris does not drop into the waste pipe.

Anything the household wants kept leaves the room first. Towel bars, a mirror frame that came with the house, a wooden vanity top that someone liked, all of it is set aside before the work begins. After the first hammer swing, nothing in the room is a safe place for a keepsake.

In what order do the pieces come out?

Fixtures go first because they are easy to remove and they open up space. The toilet comes up after the supply line is disconnected and the tank is drained, and it is carried straight out wrapped in plastic. The vanity follows: supply lines, drain trap, a few screws into the wall, and the cabinet slides out. A pedestal sink may be held by a single lag bolt and a bead of caulk.

Then the surfaces. Wall tile set in a mortar bed comes off with a demo hammer and a wide chisel, working from the top down so that broken pieces fall away from the worker. Tile set in thinset over drywall comes off in a different way, because the drywall behind it is often soft with moisture and takes the tile with it. A reciprocating saw cuts the drywall into panels that peel off the studs in large sections, which is faster than chipping each tile and creates less dust.

The tub is the slow piece. A cast iron tub weighs several hundred pounds and rarely comes out whole. The crew breaks it in place with a sledge, wearing eye and ear protection, covering the tub with a blanket first so enamel shards stay in the shell, and carries the pieces out in buckets. A steel or fiberglass tub is lighter and often lifts out after the fasteners are cut. Either way, the surround has to be opened first so the flange can be reached.

What do crews find behind a bathroom wall in older Redding houses?

The wall cavity tells the story of every repair the house has had. In homes around Downtown Redding built before the war, a bathroom may have plaster over lath on the walls, with a layer of tile set directly on the plaster. The lath comes off with a flat bar, plaster and all, and the nails in it make a bag of debris that has to be handled carefully.

Galvanized supply pipe is common in older houses. It corrodes from the inside, and the section that looks fine from outside can be nearly closed by scale. Cast iron drain pipe rusts through at the bottom of a bend. A leak that has run for years may have left a stained subfloor, and a soft subfloor is easy to find: a screwdriver pushes into it without effort. Wherever rot is found, the crew marks the extent of it, because the replacement area needs to reach solid framing on each side.

Sometimes the bathroom floor has two or three layers. Sheet vinyl on top of an older vinyl, on top of a plywood underlayment, on top of the original plank subfloor. Old vinyl and the black mastic under it can contain asbestos in houses of a certain age, so a floor that predates the late 1980s is sampled before it is torn up. If the sample is positive, the demolition of that floor waits for a licensed abatement crew.

How long does the whole tear-out take?

A standard bathroom with a vanity, toilet, tub and tile surround takes a crew one full day to strip to the studs and a half day to haul everything out and clean. A small powder room can be finished before lunch. A primary bath with a large tiled shower, a built-in bench, and a mortar floor takes longer because mortar beds are heavy and have to be broken into pieces small enough to carry. A floor with radiant heat wires embedded in the mortar slows things down more, because the wires have to be located and the circuit isolated before the chisel goes in.

Weather in the Sacramento Valley matters even indoors. In July, a bathroom with the air handler off and the window open can pass ninety degrees before noon, so tear-outs are started early. In winter the main concern is the path to the dumpster, which turns to mud after rain unless plywood is laid down.

What does the room look like when the demolition is finished?

Bare studs on the walls, a clean subfloor, capped supply lines with their valves closed, and drain openings stuffed and taped. The ceiling is usually left in place unless it shows water damage or the plan moves the fan. Every opening is clear of debris, nails are pulled or bent flat, and the floor is swept and vacuumed with a filtered vacuum so the next trade is not working in plaster dust.

A good tear-out leaves information as well as an empty room. The crew can tell the next trade where the framing is sound, where it is not, which pipes should be replaced while the walls are open, and where the subfloor needs patching. A plumber who sees the open walls can reroute a drain or move the supply lines in an hour, work that would take a day with the walls closed. That is the practical reason to open everything first and decide afterward.

What are the common questions homeowners ask?

Can the household stay in the house? Yes, as long as there is another bathroom. The work area is sealed and the dust stays inside it. Without a second bathroom, the plan has to include a portable toilet or a stay elsewhere for the few days that the plumbing is off.

Does every wall have to come off? No. Only the wet walls, the ones around the tub or shower, usually need to open completely. The dry walls can be patched. Opening the whole room is a decision made for plumbing access or for hidden damage.

What if the tear-out finds mold? Small patches on the back of old drywall are removed with the drywall. A wide area of black growth on framing stops the job for a closer look, and the plan changes from demolition to remediation first.

A bathroom tear-out is fast when the shutoffs, protection and testing are done first. Everything after that is just taking the room apart in the right order.

Why does debris sorting matter on an interior demolition?

A kitchen or bathroom tear-out produces a surprising amount of material, and not all of it can go in the same container. A single room of plaster and lath is heavy enough to hit a dumpster weight limit before the box is full, while a room of cabinets and trim fills the volume and weighs very little. The crew sorts as they work, because sorting later means handling every piece twice. Sorting also decides how many dumpster trips the job needs, and a trip is the slowest part of any tear-out.

Around Redding the disposal sites sit in Shasta County, and each one has its own rules about what it accepts and how it wants loads separated. A crew that works in the area learns these early. The main categories are the same everywhere, though, and they explain most of what happens in the yard.

What are the main categories of tear-out debris?

Most interior demolition debris falls into six groups. The table lays them out by what they are, how they behave in a dumpster and what usually happens to them.

Material	Where it comes from	How it behaves	Where it goes
Drywall	Walls and ceilings in newer homes	Light, bulky, very dusty when broken	Mixed debris, or a separate drywall load if the site asks
Plaster and lath	Walls in houses built before the war	Very heavy, full of nails	Mixed debris, filled in small loads because of weight
Wood framing and trim	Studs, headers, baseboard, cabinets	Bulky, light, may carry nails and paint	Wood load, or mixed debris if painted or treated
Metal	Pipe, ductwork, tubs, nails, brackets	Heavy, often sorted by hand	Scrap metal, set aside before the dumpster fills
Concrete, tile and masonry	Mortar beds, slabs, hearths, tile	Dense, heavy, compact	Inert load, usually in its own container
Hazardous items	Old paint, fluorescent tubes, some insulation	Cannot go in the dumpster	Special handling, never mixed in

How does the order of loading change the trip count?

Heavy and compact material goes in first, on the floor of the container, and light bulky material goes on top. A dumpster loaded the other way around ends up with cabinets crushed under plaster, which wastes volume. A crew that breaks cabinets into flat sections and stacks them like cordwood gets noticeably more into the same box than a crew that tosses them in whole.

Concrete, tile and brick are kept apart from everything else. A mortar bed from a bathroom floor can fill a heavy duty wheelbarrow with just a few chunks. If these are mixed with household debris, the whole load is treated as mixed and falls into the heavier weight bracket at the dump. Keeping them separate often takes a second small container, but it keeps the main box useful.

What happens to drywall, and why is it treated differently?

Drywall is gypsum between paper, and the paper holds moisture. In a landfill wet gypsum can produce a foul gas, so some sites ask for drywall to be kept out of the mixed load. Where the site accepts a clean drywall load, the crew bags the dust and cuts sheets into pieces that fit flat. Painted drywall is acceptable. Drywall with old texture sprayed on the ceiling is a question mark in houses of a certain age, because that texture sometimes carried asbestos, and a test comes first.

The practical side is simple. Breaking a wall into sheets, not crumbs, keeps the dust down inside the house and the volume down in the dumpster. A reciprocating saw cuts the board along the studs, the panels peel away, and a worker carries them out two at a time.

What gets pulled out and kept?

Salvage is limited on a tear-out, but a few things are worth setting aside. Copper pipe and brass fittings sell as scrap. Solid wood doors, original hardware and older plumbing fixtures with a clean finish can be reused or sold. Hardwood flooring that is intact can be lifted board by board with a flat bar, although it takes time and splits often. Cabinets in decent condition can go to a reuse store or a garage if the household wants them.

Anything electrical is handled carefully. Old wiring that is cut out is pulled from the box back to the nearest junction, and the ends are capped. Copper wire is scrap, but the crew only pulls it after the circuit is confirmed dead at the panel.

What cannot go in the dumpster?

Paint cans with liquid in them, solvents, adhesives, fluorescent tubes, batteries and some old thermostats go to a hazardous waste collection, not a container. A dumpster hauler will refuse a load with these inside, and the dump may turn a truck away. Regulated asbestos material is never loaded by a demolition crew. It is bagged and removed by a licensed abatement contractor, with paperwork that follows the waste to a site permitted to take it.

Lead paint debris is a gray area for homeowners. Paint chips and dust from a house built before 1978 are handled with wet methods and sealed in heavy bags before they go in a container. The bagging keeps dust out of the air at the dumpster as well as at the house.

Where does the dumpster sit, and how does it get filled?

A ten or twenty yard container is usual for a single room tear-out, placed as close to the door as the driveway allows. Plywood goes under the wheels if the driveway is soft or new. The path from the room to the box is covered with hardboard, and the crew uses a wheelbarrow or a heavy cart on that path rather than carrying loose pieces through the house.

In summer, the container sits in direct sun and gets hot to the touch, so loading is done early. In winter, a wet container floor makes plaster pasty and heavier. A tarp over the top keeps rain out and keeps light debris from blowing across a neighbor's yard, which matters in neighborhoods around Turtle Bay and Anderson where lots are open and the wind comes off the Sacramento River.

How is the final cleanup handled?

The last load is sweepings. Fine dust, nail heads, broken tile edges and plastic sheeting are collected with a shop vacuum and bagged. Magnets are dragged over the driveway and the lawn near the box to pick up stray nails, because one nail in a tire costs more time than the whole cleanup. The house is left with swept floors and an empty room, and the container is called for pickup the same day if the loads are done.

A crew that walks the yard before the first load, and decides where each pile will go, saves more time than any tool does. Sorting is half of what a tear-out crew does, and it is the half that homeowners never see. A job sorted well takes fewer trips and leaves a cleaner yard.
