Asbestos and Lead Paint in Older Detroit Homes

Two things will stop a Detroit rehab dead, and neither is the budget. Asbestos and lead. Both sit in most of the housing stock here, both are manageable handled properly, and both turn into a real mess if you swing a sledgehammer first.

I have run roll-offs out of the west side since 2014. This is the plain version of what to know before you start — not legal advice, and no substitute for a real inspection. Rules change, so confirm current requirements with EGLE, the state and the EPA first.

Why this matters more in Detroit

Most of Detroit's housing went up between roughly 1900 and 1955. Brick bungalows, Tudors, four-squares, colonials. Plaster and lath over wood studs, full basements, often with the footprint of an old octopus furnace still on the floor. That era used asbestos as a building material and lead as a paint pigment.

Two dates matter. Pre-1978 means assume lead paint. Pre-1980 means assume asbestos until testing says otherwise. In Brightmoor, Bagley, Russell Woods, Morningside and the North End, every house on the block clears both by decades. Anyone working a gut rehab or flip in Detroit should plan for this from day one.

Where asbestos actually turns up in a Detroit house

Floor tile and the black mastic under it

The most common one by far. Vinyl-asbestos tile in 9x9 squares is a strong tell — that size largely disappeared by the late 1970s. 12x12 tile can also contain asbestos, so do not treat the bigger square as clean. Underneath either you often find black cutback mastic, which frequently carries more asbestos than the tile. Kitchens, baths, back halls and enclosed porches are the usual spots, often with three generations of flooring stacked up.

Pipe wrap, duct wrap and the octopus furnace

Head to the basement. The old gravity furnace ran big round ducts across the ceiling joists, and both ducts and heating pipes were routinely wrapped. Look for a chalky white or grey plaster-like coating over joints, corrugated cardboard-looking wrap, or canvas over insulation. Elbows often got moulded covers like grey papier-mâché. It is old, dry and crumbles if you brush it, and it is what most often turns a basement cleanout into a job for a professional.

Plaster, ceilings, siding and roofing

Detroit is a plaster town, and some plaster systems — hard finish skim coats and patching compounds especially — contain asbestos. Textured and sprayed ceilings from the 1950s through the 1970s are suspect too. Outside, cement-asbestos siding shows up as small, brittle, slightly wavy shingles laid over the original wood, and cement-asbestos roof shingles appear on larger houses. Roofing felt, built-up layers, flashing cement and coatings can all contain asbestos, which matters on a tear-off. Window glazing putty on old sash is one nobody thinks of. Add boiler jackets, flue connectors, transite panels and vermiculite attic insulation.

Intact and undisturbed is generally not the hazard

Asbestos is dangerous when fibres go airborne and get breathed in. A sound, well-adhered 9x9 tile floor with nothing crumbling is generally not putting fibres in the air. The same tile hit with a chipping hammer, a floor grinder or an unfiltered shop vac absolutely is. The hazard is the disturbance, not the presence of the material.

Which gives you an option people forget: leave it alone. Often the right call on a sound tile floor is to encapsulate and float new flooring over the top, and on sound cement-asbestos siding overcladding can beat removal. Every square foot you do not disturb is one you do not have to abate or document. What cannot stay is the friable material: crumbling pipe and duct insulation, damaged boiler wrap, deteriorated ceiling texture.

Only testing tells you

Nobody identifies asbestos by eye, and a good guess is not a defensible basis for demolition. A qualified inspector takes small bulk samples and an accredited lab returns a yes or no with a percentage. Sampling is cheap next to the alternative — a contaminated house, a rejected load, a stop-work order. Sample every material and every layer: tile and mastic are two samples, not one. Do not DIY sampling on friable material, because taking the sample is a disturbance.

Licensed abatement, EGLE and demolition notification

Asbestos work in Michigan is regulated. EGLE and the state oversee accreditation of inspectors and abatement contractors, notification, work practices and disposal. Removing regulated material takes a licensed abatement contractor with containment, negative air and documented waste handling — not a general crew with a box of dust masks.

Demolition is its own trigger. Under federal NESHAP rules, demolishing a structure generally requires an asbestos inspection beforehand plus a notification to the regulating agency, and that notification generally applies whether or not asbestos is found. That catches people on garage and back-lot teardowns. If you are pulling a demolition permit through the City of Detroit or working a Land Bank parcel, build the inspection and notification waiting period into the schedule before the excavator is booked. Thresholds change, so confirm the current process with EGLE and the city.

We cannot take asbestos-containing material in any container

Straight and clear: no asbestos-containing material goes in one of our roll-offs. Ever. Not bagged, not wetted, not "just a little pipe wrap in the corner." Regulated asbestos waste has its own handling, manifesting and disposal chain to a permitted facility; a construction container is not part of it. I would far rather reschedule than haul a contaminated load. Tell me the day before that testing came back positive and we move the drop, you abate, we come back for the clean debris.

If it turns up mid-job — somebody pulls carpet and finds 9x9, or opens a soffit and finds wrapped duct — stop work in that area. Do not sweep it, do not shop-vac it, do not keep loading. Close the space off and call us. If a container is already on site we will work out whether what is in it can still go. Then get a sample taken. A clear picture of what goes in a Wayne County container stops this happening at the scale house.

Lead paint: the pre-1978 problem

Lead paint stayed in residential use until it was banned for that purpose in 1978, and Detroit's housing predates that ban by a wide margin. The city has carried among the highest childhood lead-exposure rates in Michigan for years, which is why a careless rehab on an occupied block is a public-health issue, not paperwork. MDHHS publishes current guidance on childhood lead exposure and testing.

The rule to know is the EPA Renovation, Repair and Painting rule — RRP. Broadly, firms doing renovation, repair or painting that disturbs painted surfaces in pre-1978 housing and child-occupied facilities must be EPA-certified, use certified renovators, follow lead-safe work practices and inform occupants. Thresholds and exemptions exist, so confirm the current version with the EPA.

• Contain the area. Plastic down, doorways sealed, HVAC off so you are not pumping dust house-wide.
• Wet methods. Mist before scraping. Wet dust does not travel.
• HEPA only. A regular shop vac blows fine lead dust straight back into the room.
• Clean as you go. Wet-wipe, HEPA, wet-wipe again. Bag debris inside the work area.
• Watch the soil. Decades of chips off old siding land at the drip line, where kids play. Lay plastic before exterior scraping.

Two things you should never do on a pre-1978 house: dry sanding painted surfaces, and open-flame or torch stripping. Dry sanding puts invisible lead dust through the whole building and it does not come out with a broom. Burning lead paint puts lead fume in the air, and on a plaster-and-lath house it starts fires. Chemical strippers, low-temperature infrared, wet scraping and replacement are safer.

Homeowner work versus professional work

Reasonable for a careful homeowner on their own house: repainting sound surfaces; wet-scraping small areas with containment and a respirator; replacing a window or door as a unit rather than sanding in place; encapsulating an intact tile floor; demolition in areas tested clean; and pulling salvage before the container arrives.

Needs a professional, full stop: anything friable; pipe wrap, duct wrap, boiler insulation or vermiculite; whole-house tile and mastic; cement-asbestos siding; any demolition requiring NESHAP inspection and notification; and RRP-regulated work done for pay on someone else's pre-1978 property. If you are being paid, certification is not optional.

What it does to the timeline and budget

Plan for inspection and lab turnaround up front, an abatement window if anything is positive, then clearance before your crew goes back in. On a full gut that realistically adds a couple of weeks and fixes the order of operations: abatement first, demolition second, container second. You do not want a can sitting open on a vacant block while abatement runs, because scrapping is a real risk here. We run next-day delivery and swap-outs, so there is no advantage to the box arriving before you can fill it. Unsure how to phase it? Talk it through before you schedule.

Where the debris legally goes once it is properly abated

Regulated asbestos waste leaves with the abatement contractor, in their packaging, under their documentation, to a permitted facility. Keep the paperwork — a buyer, lender or inspector may ask later.

What follows is ordinary work, and that is what our containers are for. Once a house is cleared, plaster and lath, wood, cabinetry, subfloor, roofing and general demolition debris loads normally. Plaster runs two to three times the weight of drywall for the same volume, so size for weight — which is why a 20 yard roll-off often beats a bigger box on a plaster gut, while a lighter bungalow clean-out may justify a 30 yard container. Our Detroit sizing guide covers weight properly. Lead-painted components are generally handled as ordinary construction debris, but confirm current handling with the county and the state, because this gets revised.

Keep the other streams straight. Yard waste cannot be landfilled in Michigan and goes as a separate clean load, and leftover paint, solvents and household chemicals belong at a Wayne County or municipal household hazardous waste drop-off. Refrigerant appliances, tires and lead-acid batteries have their own routes, covered in our Wayne County recycling guide. On a multi-phase rehab a construction dumpster rental on swap-outs beats one pull, and residential dumpster rental covers smaller jobs. If the container sits off your own driveway, check Detroit dumpster permits first.

The short version: assume asbestos in a pre-1980 Detroit house and lead paint in a pre-1978 one, and test rather than guess. If you are planning a gut on an older house and want to talk through phasing and what we can and cannot take, call Andre and the crew at DTR Dumpster Rental Detroit on (586) 600-7076. We are on Meyers off Schoolcraft, we cover Detroit, Wayne County and metro Detroit, and we would rather have the conversation before the delivery than after.
