Home Renovation and Building Materials

If you or a loved one has been diagnosed with mesothelioma after years of working on an older house, you may have a valid claim — and you may not be aware of the full range of compensation available to your family. The exposure in these cases came from products sold to homeowners by name-brand manufacturers, and it is proved the way any product exposure is proved.

The Consumer Product Safety Commission states plainly that until the 1970s, many types of building products and insulation materials used in homes contained asbestos. Its guide lists where. Patching and joint compounds for walls and ceilings, and textured paints. Soundproofing or decorative material sprayed on walls and ceilings. Resilient floor tiles, the backing on vinyl sheet flooring, and the adhesives used to install floor tile. Asbestos cement roofing, shingles, and siding. Steam pipes, boilers, and furnace ducts insulated with an asbestos blanket or asbestos paper tape.

That list describes most of a house built between the 1940s and the 1970s, and very likely one you have lived in. The joint compound between every sheet of drywall. The sparkle ceiling in the bedrooms. The nine-inch floor tiles in the kitchen and the black adhesive under them. The shingles on the roof and the siding on the walls. The white wrap on the basement pipes.

Keep in mind that the EPA's guidance is that asbestos-containing material in good condition that will not be disturbed generally will not release fibers. The house was not the hazard while it sat there. The hazard began when someone went to work on it.

Renovation is, by definition, the disturbance of building materials. Every technique a homeowner used on an older house was one that the EPA lists as a way fiber is released.

The EPA states that asbestos-containing materials may release fibers when they are disturbed, damaged, removed improperly, repaired, cut, torn, sanded, sawed, drilled or scraped. Read that list against a weekend of home improvement. Joint compound was sanded smooth, by hand, in a closed room, with the dust settling on everything. Popcorn ceilings were scraped down. Floor tile was pried up and the adhesive scraped or ground off. Siding and roofing shingles were cut with a circular saw. Pipe insulation was torn off to get at a leak. Then the whole mess was swept, and sweeping put it back into the air.

None of that work was done with a respirator or sealed plastic, because nobody told you the material contained asbestos. The products were sold at the hardware store in bags and boxes with brand names on them, and the instructions said to sand between coats.

The exposure was concentrated. A closed room, a hand sander, a face a foot from the wall, for hours. It repeated. Most people who renovated one house renovated the next, and many worked on a house continuously for years. It spread. Dust carried on clothing and shoes through the rest of the house and settled into the carpet and the furniture, where it was disturbed again with every footstep.

One building material deserves its own section because so many houses have it and so few families knew what it was.

Vermiculite is a mineral that expands when heated into light, fire-resistant flakes, and it was poured loose between attic joists as insulation for decades. The EPA reports that a mine near Libby, Montana, was the source of over 70 percent of all vermiculite sold in the United States from 1919 to 1990, that there was also a deposit of asbestos at that mine, and that the vermiculite from Libby was contaminated with asbestos. The agency's advice to homeowners today is to assume vermiculite insulation is from Libby and to treat it as if it contained asbestos.

That advice arrived long after the exposure. For decades families stored boxes in the attic, ran wiring through it, added insulation over it, and let children play in it, and your family may have done all four. Renovating an attic, or finishing it as a bedroom, meant shoveling the material out by hand. The EPA's own page now says to keep stored items out of an attic with vermiculite, to keep children out of it, and to hire a professional asbestos contractor before any renovation that would disturb it. It also states that asbestos causes cancer and other diseases and that there is no known safe level of asbestos exposure.

If your family's house had loose, shiny, pebble-like insulation in the attic, that is worth telling us about, and it is worth telling anyone who lives there now.

Renovation exposure begins with the person holding the sander and does not end there.

The person doing the work carries the heaviest exposure. That was often the homeowner, frequently a man doing weekend work over years, and sometimes a woman who did the painting, patching, and floor work herself. If you did that work, your own account of what you sanded, scraped, and tore out is the case.

Everyone living in the house breathed the dust that spread through it and settled into it. Spouses cleaned it up. Children played in rooms that had been sanded the day before. This is why a renovation claim can belong to a family member who never picked up a tool, and why mesothelioma in a woman with no work history can trace to a house. The CDC notes that exposure can occur indoors when older building materials containing asbestos are present.

Children who helped. A teenager handed the tools, held the flashlight in the attic, or swept up afterward, and the latency of the disease means that exposure can surface in middle age.

The National Cancer Institute records that it can take from 10 to 40 years or more for symptoms of an asbestos-related condition to appear, so the house in question may be one your family left long ago.

The federal record of asbestos in building materials matters to your case for what it shows about timing.

In 1973 the EPA banned spray-applied asbestos surfacing for fireproofing and insulating, and in 1975 it banned the installation of friable asbestos pipe and block insulation on boilers and hot water tanks, as the agency's account of federal actions records. In 1977 the Consumer Product Safety Commission banned asbestos in wall patching compounds, a ban the CPSC guide dates to that year for patching compounds and textured paints. The EPA's broader 1989 rule banned some products and all new uses, and the agency's chrysotile rule of March 2024 prohibited the ongoing uses of the only form of asbestos still imported, naming mesothelioma among the diseases it protects against.

Two things follow. The hazard was established well before the bans, which is why the bans happened. And the bans did nothing about the material already in the walls, floors, and attics of the homes built with it, which stayed there to be sanded and scraped by the next owner.

In a claim, the question is framed carefully. What did each manufacturer know about the fiber its joint compound, tile, or insulation released when it was sanded or cut, when did it know it, and what did it tell the homeowner on the bag or the box. Those answers come from the company's own documents and from the histories of what warnings were and were not given.

A renovation claim is a product liability claim against the companies that manufactured and sold the building materials.

The product manufacturers are the defendants. The joint compound company, the floor tile company, the insulation company, the siding company. Many were large national brands whose products can be identified from a description, and whose records survive. The theories are the ordinary ones: an unreasonably dangerous product, failure to warn of a hazard the company knew or should have known about, and negligence in continuing to sell asbestos-containing goods to homeowners who would sand them.

Bankruptcy trusts pay a large share of building material claims. Many of the largest manufacturers of joint compound, insulation, cement products, and flooring reorganized in bankruptcy and were required to fund trusts for asbestos claimants. Claims against them are made through a filing process, described in asbestos bankruptcy trust claims, and how trust claims and lawsuits are run together is covered in trust claims and tort suits.

The vermiculite supplier is a distinct defendant for attic insulation claims, with its own trust process.

Contractors and premises owners can be defendants where the renovation was done by hired workers, or where the exposure happened in a rental. For a homeowner who did the work in a house they owned, the claim is against the manufacturers.

A renovation case has one advantage that no occupational case has. The evidence may still be standing.

The house itself. If the house exists and the materials are in place, they can be sampled and tested, and the product can sometimes be identified by its markings or its composition. Floor tile under a newer floor, joint compound behind a wall, insulation on a basement pipe. If your family still owns the house, do not disturb the material. If it has been sold, the address and the years of ownership still let the house be documented.

The work and the products. What was done, in which rooms, in which years, and with which products. Homeowners often remember the brand of joint compound or the flooring they laid, and receipts, photographs, permits, and before-and-after pictures all help. A neighbor who helped or watched is a witness.

The routine of the household during the work. Who was home, who cleaned up, where the dust went. This is the exposure of every family member who did not hold the tools, and it needs to be recorded by more than one person.

The medical record. The pathology, imaging, and treating records that established the diagnosis, gathered in full.

Every other exposure. A homeowner who renovated may also have had a trade, and a household with a renovation may also have had a worker bringing fiber home. Each is recorded and each is assessed on its own contribution, because asbestos cases regularly involve several sources and the claim is brought against all of them. Related routes are covered in construction and insulation trades and take-home and secondary exposure.

The deadline rules are the same as in any asbestos case. The filing deadline is set by the governing state, usually counted from the date of diagnosis, with wrongful death handled separately; the detail is in statute of limitations in asbestos cases. Where a case is filed when the house was in one state and the manufacturers are elsewhere is covered in venue and jurisdiction.

If the asbestos in your life was a house, write down the addresses, the years, and the work that was done in each. Note who did it, who was home, and any products you can name. If the house still stands and the materials are still in it, leave them alone and tell us.

There is no fee unless we win. A first conversation costs nothing, and the list you write tonight is enough to start it.
