Asbestos Removal

This is the post that I’ve been putting off writing. Why? I was still dealing with the shock of it all. The gist of it is, if you think your home is safe from asbestos, you could be dead wrong! I thought our home was in the asbestos-free time frame, but I was sorely mistaken.  

Background: What started as a small leak turned into a massive gut of our kitchen. The disaster restoration team came in and started assessing the damage. What happened next was a downward spiral of issues I pray never happens to you. The polybutylene pipe failure from two weeks ago turned into a full blown mold remediation (luckily it wasn’t black mold.) Shortly after removing the water soaked base cabinets in our kitchen, the project manager discovered old vinyl flooring under our newer vinyl flooring. He told me that they sent a sample to the lab for asbestos testing. I said, “Okay.” And dismissed it knowing that our house couldn’t possibly contain asbestos. The next morning I got a phone call, “The lab results came back and that old flooring tested positive for asbestos.”

What I learned over the next few days about asbestos both scared me and re-assured me. Now that our home is officially asbestos-free and we’ve finally moved back into the house, I’m emotionally ready to share with you what I learned.

What is asbestos? (source: EPA.gov)
Asbestos is a mineral fiber. It can be positively identified only with a special type of microscope. There are several types of asbestos fibers. In the past, asbestos was added to a variety of products to strengthen them and to provide heat insulation and fire resistance. Asbestos as a building material made sense before it was discovered to cause health problems. It was heat and fire resistant and the glues that contain asbestos work REALLY well. You can’t get glue for vinyl flooring today that sticks as well as the asbestos based glues. Thankfully, asbestos has been banned in the US.

But, here is the crazy thing: Back in the early 1900’s asbestos was suspected to be a health hazard. In 1924, a UK citizen was the first person diagnosed with Asbestosis (progressive fibrosis of the lungs.) In 1931, the term Mesothelioma (a rare form of cancer) was used in medical literature. But, the risks and dangers of asbestos were swept under the rug and hidden until the 1970’s. Finally, in 1989 asbestos in building materials was phased out and eventually banned in 2003. That is almost 80 years after the dangers of asbestos were first discovered! Which means that in the meantime asbestos was used in almost a million residences and buildings. And over 100,000 people have become ill or died from asbestos exposure.

Asbestos is used in (but not limited to) per Wikipedia:

  • Roofing and siding materials
  • Some roofing and siding shingles are made of asbestos cement
  • Insulation of a home built between 1930-1950
  • Attic and wall insulation as vermiculite ore
  • Textured paint and wall patching
  • Artificial ashes and embers used in gas fireplaces
  • Old stove-top pads
  • Walls and floors around woodburning stoves can have asbestos fiber, millwork or concrete pads
  • Vinyl floor tiles and the backing on vinyl sheet flooring
  • Vinyl floor adhesives
  • Asbestos blanket or tape on hot water and steam pipes in older homes
  • Oil and coal furnaces door gasket insulation

The bottom line is that your home could have asbestos products even if it was built in and prior to 2003. The asbestos abatement team told me that just because there was a ban placed on the use of asbestos, there were still products containing it on store shelves. For this reason, you should never assume that your home is asbestos-free. It is much safer to have a professional test for asbestos if you don’t know. Then discover that you were exposed when it is too late.

What to do if you suspect (and even if you don’t suspect) that you have an asbestos product in your home:

First of all, don’t freak out. Call a professional asbestos abatement company and have them do a quick test on the product. They will take a 1″ sample of the material and perform a PLM (Polarized Light Microscopy) test by looking for asbestos fiber structures under a microscope. If it is determined that you have asbestos, you need to determine the risk of the fibers being released into the air. If you have asbestos flooring that is in good condition (not flaking, damaged or will be tampered with) you can lay new flooring over top of the old floor. In the case of our vinyl flooring, one of the previous owners had added new flooring on top of the old. This is acceptable, but it must be disclosed that there is asbestos flooring in the home when you go to sell. It is presumably safe to live in a home that has asbestos products as long as they aren’t at risk of creating air borne fibers.

In our case, the mold remediation team had to remove the water soaked floor and would be damaging the old asbestos vinyl underneath. This could loosen and expose fibers that could be inhaled and potentially lead to health problems.

How Asbestos is Removed?

I was told that we could stay in the house during the abatement, but there was no way I was going to chance having my kids in the house. We decided to move everyone out of the house (complicated by the fact that we were getting headaches from the mold.)

The abatement team arrived and sealed off the room(s) completely. Doorways, ducts and even the windows are sealed with plastic. Big scary asbestos signs are placed on every doorway to deter people from entering.

Two giant HEPA filters are installed outside a window and suck the air out of the room. This creates negative air pressure which prevents air from escaping into the rest of the house.

Asbestos Removal

The asbestos abatement team wears disposable suits (and I was told even disposable underwear.)  They wear respirators and gloves.

The floor boards are cut into manageable sections and the edges are taped off to contain the asbestos backing and glue under the vinyl. The sheets are loaded into a truck. All debris is vacuumed and cleaned from the room and disposed of in plastic bags. All the contaminated materials, clothing, etc. are hauled back to the abatement company where they are dumped into a special sealed dumpster for asbestos products.

After the abatement team is done, they must strip down and take a shower (usually a portable shower is brought to the job site.) Only after the shower can they put on their regular clothes.

Air test for Asbestos

After the abatement is complete, an air test must be performed before anyone can enter the room without protective gear. A TEM (Transmission Electron Microscopy) or a PCM (Phase Contrast Microscopy) air sample is analyzed. In our house, the TEM was used which is supposedly more accurate. The technician was a trained professional who put on his own protective gear. He ran a leaf blower around the room to stir up any dust and fibers that may have settled on the floor and in crevices. Then ran a small vacuum pump that sucked air through a filter for 45 minutes.
 
An acceptable asbestos air test will come back with less than .01 fibers per cc. Luckily our home was clear and we were allowed to move back in. But, now this is our reality:

That’s right, we now have a scooter track in our home. I may miss our kitchen, but the boys don’t seem to mind.

    I had no idea that asbestos could be basically anywhere in an older home. I can see why it would be smart to have any house you are looking of buying tested for it. My sister noticed her kitchen floor would shift up and down while she walked on it. They eventually had it tested and found it has asbestos. It took them about a month to get it all taken care of. What a nightmare.

    Thanks for sharing your story. There needs to be more public awareness about asbestos. I’m sorry that you had to go through all of that. It must have been such a stressful time for you and your family.

    My husband and I are under contract to buy a 1969 ranch, which a house flipper remodeled. I wonder how much asbestos was in the house and what care the renovators took, if any, in removing it. I’ve learned that before the remodel, the house had that horrible 1960s wood paneling throughout, which would have had asbestos mastic. The drywall has been replaced, and, thankfully, most of the floors are hardwood, but I’m sure that there were other sources of asbestos in a house from this era. I noticed when we toured the house a couple of days ago that a lot of dust from the renovation had collected in the vents and air ducts. So now I’m envisioning friable asbestos floating around in there.

    11 days ago, the pipe that fills the toilet tank busted while i was at work. I came home to 4″ of water throughout most of my apartment. ( i rent) we got most of it up that night, and i continued the next day. A flood restoration company came out and started the process of pulling up all the carpeting and some of the kitchen flooring. A guy came out to test for mold and asbestos, all work has come to a complete halt. one day was it, and they just left the dehumidifiers running. nothing has happend since, the guy who took the samples said he needed state okay on it, but still not one thing has been done… my question is isn’t there a time limit for this sort of thing, so i can get my apartment fixed

    Hi Brittany,
    This is great info – I am currently in the middle of what sounds like a similar project. Water leak, leads to pulling up the floor, 3 layers of vinyl, first 2 layers clear of asbestos – 3rd layer positive! Ugh, not to mention the mold too. My question for you – did you take all the appliances and everything out of kitchen before the asbestos removal? I am curious since we are mainly tearing out the floor – does everything in the upper cabinets need to be removed? I would assume yes, based on what you mention about your experience, but would be interested to hear what you think. Thanks!

      Kathy, our kitchen was already gutted and the upper cabinets were emptied when they were doing the mold abatement. If I were you, I would empty them and seal them or thoroughly clean them afterwards. And yes, the entire kitchen was emptied from the backsplash down. I would expect you’d need to do that when ripping out the flooring down to the subfloor. I also wouldn’t recommend taking on this job yourself. But, that’s your call.

        We are dealing with a similar issue: water damage in kitchen resulting in mold, subsequent discovery of asbestos behind the wall. Insurance company is not authorizing the removal of the kitchen appliances before the abatement process begins, but insists that wrapping them in plastic is sufficient. Others have said the appliances should be removed, which puts us at somewhat of a standstill.

    3.5K for just one room?! omg, the abatement co. is recommending a gut of the *whole house* (1300 sf); I was thinking it’d be around 10-12K, but am now revising that to 15-20K.

    gah!

      Marie, that cost depends on a lot of different factors (location, the material with asbestos, work needed to remove it, cost to dump in a containment area, etc.) I wouldn’t freak out until you get a quote.
