Health Hazards of Home Demolitions and Renovations
Thinking about pulling out the sledge hammer and bashing away? If so, It is extremely important to be aware of the many health hazards involved in doing a home demolition project as well as simple home renovations. This is because a great many toxic materials were used in home building. Even something as common as dust presents a serious health hazard.*
I think of all the times I have stripped wood, scraped paint, been in homes being gutted, and never paid attention to all the dust.
How could dust be a hazard? Dust may be considered merely a nuisance, but that dust could have asbestos - a demolition hazard that is known to be extremely toxic. Older homes were commonly built with materials that we know today to be hazardous to our health. In addition to asbestos, this includes lead, mercury and much more.
Below is a list of some of the hazards to be found in a demolition or renovation project.
1- Asbestos, a mineral fiber, has insulation and fire-retardant properties and was regularly used in a multitude of building projects including flooring, ceiling tiles and roofing shingles. Microscopic fibers from asbestos can become airborne and inhaled into the lungs. Asbestos is now known to cause mesothelioma -- which is a cancer of the lining of the abdominal cavity and chest, as well as asbestosis -- which is a scarring of the lungs.
Warning: If there is any possibility at all that asbestos is in your home, demolition should only be done by an expert. Consult with a licensed asbestos abatement contractor who will explain how the asbestos removal will be done, as well as the necessary steps that will be taken to seal off the rest of your home.
2 - Formaldehyde - is a known carcinogen, but is still widely used as an industrial chemical. In the home, formaldehyde is found in particleboard or the type of pressed wood product used in cabinetry. It is also found in plywood paneling and most types of fiberglass insulation. Very low levels of formaldehyde can cause nausea, difficulty in breathing, watery eyes and a burning sensation in the eyes and throat.
3 - Lead - was used in many painting projects and has long been known to be a harmful pollutant. During a demolition project, the lead found in dust, fumes or vapor, often from paint stripping, will become airborne and get into the lungs. High amounts of lead are known to cause headaches, weight loss, anemia, fatigue, irritability, constipation, stomach pains and nausea.
4 - Polychlorinated Biphenyls are also known as PCBs. PCBs we now know can cause a wide range of health problems. Commonly used in the home in paint, as well as caulking and plastics, you will also find PCBs in older electrical equipment used prior to the year 1977 -- this is the year PCBs were banned in paint. The chemical can cause cancer and also non-cancer conditions in animals - which includes disorders of the reproductive system, nervous system, immune system and the endocrine system.
5 - Volatile Organic Compounds also known as VOCs - VOCs are emitted through paints, paint strippers, pesticides, adhesives, cleaning products, furniture and building materials. VOCs are volatile due to the fact that they evaporate at room temperature, thereby creating a polluted indoor environment that can have a concentration that is 10x higher indoors than outdoors. Breathing VOCs during a demolition, even a small quantity, can damage both the cardiovascular and respiratory systems. (See link to safer paints to use indoors)
6 - Mercury - is found in surprising places. Mercury is in old thermostats, switches, regulators and heating systems. Just one drop of mercury can contaminate tens of thousands of gallons of water. Health hazards from mercury poisoning are liver and kidney damage, mental retardation, life-long learning disabilities, and it can also be fatal.
*General Warning About Dust:
Dust can get everywhere - all through the house, in your clothes, hair, lungs, even outside during a demolition. Because it is unknown what may be in the dust, you must always assume dust is hazardous. Silica, in the form of crystalline silica, is in concrete as well as other rock types of material. If your demolition project includes breaking up, grinding or crushing concrete, the dust can enter the body and cause silicosis - which is known to damage the lungs, cause breathing difficulties and the risk of a lung infection.

It's good that you've pointed out these hazards, Bk. Some of them, such as asbestos, can be dangerous. However, depending on the age of the house and the materials used, the danger is a little over-stated. If you wear protective gear such as a full-face respirator (or rent haz-mat suit if necessary), not just a dust mask, your chances of creating physical problems are severely diminished.
Also, if you're only renovating one or two rooms, you can put plastic sheeting on doorways and windows, to contain the dust, perhaps using a humidifier to force the dust to settle sooner.
When I grew up we were exposed to many of these things rather casually, Mercury was something we more or less played with, such as making silver coins more shiny.
This is such an important post. We had an addition added to our home so we could move my mother in about 5 years ago. The carpenters were horrible and when they were connecting the new rooms to the house the roof wasn't protected. It rained that night and half of our living room ceiling fell in. There was dust and particles everywhere. My adorable cat got lung cancer and died 2 months later. I also developed an asthmatic condition which may have been caused from all the debris in the air. It is so important to be aware of the dangers and you spelled that out very well.
Truly and excellent and informative hub. A must-read for the do-it-yourselfer.
Your hub includes excellent and very important information. Many people don't realize - or don't think about - the dangers of home renovations. This is something that we should all be aware of.
Very comprehensive and detailed hub.
Valuable information. I always care with health. You remind us about something dangerous around us. I'll bookmark this one. Thanks for share with us. Rated up!

When I think of all the home renovations I've worked on over the years with nary a thought to these kinds of hazards... I guess it's a miracle I'm still alive and breathing. Good information. Lynda
Great points~
this is a very important, informative article.
My dad was always demolishing the house(I mean renovating) and there always seemed to be dust everywhere...
These are dangers we don't think about. This is a hub I will be linking to when I write my next hub.
With so many people doing their own repair work and renovations, this is a great hub with lots of important information. Voted up and useful.
So true and with toxicity everywhere we turn - we really have to vigilant and never assume safey.
Thanks a million and rated up!
I shudder when I think of all the DIYer work I have done around the home. Thanks a lot for your list. We are up against so many hazards and don't even know it.
Rated up!
Excellent reminders especially for those of us who like to "do-it-oursleves".
It is so easy to just go on doing what you planned when it comes to work at home and mostly we are in a hurry and want to get the job done quickly.
You have done a great job putting this list together and giving me a reminder. I will use a surgical masks for the next decoration job since as you say we don“t know what substances that where used when the house was built! Thanks and voted up of course!

Good information for the do-it-yourself-er. I will book mark this one. Rated up.
I found this hub to be very useful and informative. As well as interesting. Things we may not even think about on a daily basis. Wow, thanks for the warnings! Very important stuff to know. I have a friend whom is renovating an old cabin. I will be sure and share this with him! : ) Bookmarked and up!
