Asbestos Removal Costs Residents

Asbestos removal is a very dangerous task, and should only be performed by expert contractors. Even if the dangers don't effect you directly, any adjacent property to you could contain this toxic substance and end up costing you. Residents who own property in some areas will have to fork out more cash after asbestos has been located on-site. Could you be effected by something like this in the future? Or perhaps right now?
Asbestos was used in building constructions in Sydney until it was banned by the NSW government in 1986. In my many years working in the asbestos clean up and building demolition industries around schools and public buildings I have learnt one very important thing. The most important tip you should know is that asbestos removal can be very expensive, and puts many people off renovating and buying a house for fear it might be contaminated. It does not have to be expensive, but the reason people associate expense is because of the health risks exposure to asbestos can cause. The other major advice I can give, and this applies to any service in life, not just when you suspect asbestos in your building is to shop around, get several quotes from several providers, and chose who you like best.
Recently many local Sydney residents have discovered their properties had hidden asbestos materials used in their construction. Pardon the pun, but these residents are likely to have to "cough up" a lot of money to rectify their issue. Due to the nature of councils and the health dangers involved in such issues, there can be high costs for using a professional to do the asbestos removal job properly. It is even thought that there is asbestos in parts of the Sydney Harbour Bridge.
Exposure to asbestos fibres, especially over a prolonged period can cause the health issues asbestosis, and mesothelioma. These are both chronic respiratory diseases with no known cure, and a very high chance of death for those who are diagnosed. For this reason the most important thing you can do is eliminate exposure to these dangerous building materials. If suspect material is found within a property you should have the asbestos removed by licensed professionals as quickly as possible.
Any claims of asbestos in a building, either residential or commercial should be taken very seriously due to the health problems it can cause. Any testing, toxic material identification and subsequent asbestos removal should only ever be conducted by experts, since the material is extremely hazardous to handle. According to the local building industry and public housing representative, asbestos is now being found in many buildings in developed areas and a resort island area in New South Wales during a recent inspection.
Demolition work on one large building has been halted so the council can conduct a full review of the precinct for other deadly asbestos particles. This can be a costly and time consuming activity, but is for the benefit of the communities health.
Residents should be aware as is it consistently confirmed that asbestos is continuously been found often in the old recreation rooms of local resident's buildings especially in island resort structures. It is likely that other buildings in the city, local area and throughout the nearby community, which date back to the 1970s, could also be deemed dangerous. The majority of buildings built during this time used asbestos fibre materials as a safe guard against fire. It was not properly known by the public much later that the material used is linked to health problems including cancer.
For example in a big community, the budget to bankroll the purchase and demolition of a typical resort and it's contaminated neighbouring property and land could be estimated to cost more than $10 million, for the sole purpose of safeguarding against contaminated material.
When getting involved in the operations of one of these cases in an isolated resort town, the asbestos find could impact on the removal of building materials from the property, as standard building materials are a hazard and expense in their own right. Asbestos removal requires many more safe guards, licences and handling procedures to ensure workers and residents do not inhale any of the toxic materials. It is considerably more dangerous than standard demolition work of brick and mortar and plaster material, found standard in most building blocks and construction work.
The material was commonly used in buildings from 1940 to the '80s, and now correctly identifying and removal of asbestos is becoming a widespread issue for residents and commercial buildings alike.
When dealing with asbestos this extra careful handling requires increased costs, and care from a specialist. If you live on an island, isolated property or hard to access location transporting any building materials can be costly, so you could imagine the bill might start to get expensive if they have to remove asbestos. Asbestos waste is expected to be enclosed and removed to avoid future contamination of the site.
It is important you use an expert to remove such hazardous material. Regulations can differ in certain jurisdictions, however in Sydney since January 1st 2008 an asbestos licence is required to remove more than 10 metres squared of bonded asbestos material. A licensed bonded asbestos remover can remove any amount of bonded asbestos material. Licensing for asbestos removalists in Sydney is regulated and administered by Workcover NSW.

Asbestos In Plaster

Asbestos is a natural mineral that has been used for industrial applications for the last 1900 years - Yes, 1900 years, ever since the Greeks in the first century discovered asbestos and started to use it for purposes such as heat insulation.
The asbestos fibres are very strong and are 100 to 200 times thinner than a human hair, so you can see what you're up against trying to visibly see if you have asbestos in your home.
Generally it is agreed that that asbestos in plaster is quite safe unless it's disturbed and then you will understand how easy it is to inhale the virtually invisible asbestos fibres. Once inhaled they will stick to your lung wall and can ultimately generate disease and then terminal lung cancer known as Mesothelium.
Asbestos in plaster can be defined into two types - either loosely bound fibre or firmly bound fibre:
For firmly bound asbestos fibres generally these products were made for domestic use in the 1970's and before: (Today, cellulose fibres have replaced asbestos fibres)
Roof shingles
Water or flue pipes
Textured paint
Vinyl floor tiles
The backing of vinyl floor coverings
Flexible building boards
Flat or corrugated sheeting
Plaster ceiling tiles
Plaster acoustic ceiling tiles
Loosely bound Fibres:
Loosely bound asbestos in plaster fibres are also termed 'friable' and were used mainly in older houses for insulation within heaters and stoves. Since asbestos has been off the market, glass fibres have replaced them within insulation products.
What should I do if I identify asbestos in my house?
If the panels or tiles or whatever asbestos you may find is in good condition and painted you really have no reason to fear it as long as it's left alone and not disturbed. If you have asbestos panels outside for cladding, likewise, if they are not broken and painted, no reason to worry. However, if you do have broken panels then they should be replaced. This can be undertaken by professionals, or, yourself if you want to but only if you have the proper protective equipment and they are thoroughly watered down to stop any microscopic fibres from becoming airborne and they are carefully disposed of so not to conflict danger on others as well.
So, if you do have asbestos, it really is better just to keep it where it is, if it's not disturbed because it's a highly skilled and expensive job disposing of it and it really is perfectly safe unless you are remodeling your home, office or factory.

The Top 5 Places to Check If You Think Your House Has Asbestos


After scientists discovered that asbestos fibers cause asbestosis and mesothelioma cancer, this material became heavily regulated in the United States. Homes are no longer built with materials containing asbestos fibers. However, some residential structures built before the 1970s might still contain asbestos. If you suspect that your house has asbestos, you should hire a professional to check these five main places.
1. Boiler and Hot Water Pipe Insulation. If you live in an older home, you should have your boiler and hot water pipes inspected for asbestos. Until the 1970s, many hot water and steam pipes were covered with a protective coating of asbestos. In addition, some boilers and pipes were wrapped in asbestos blankets for heat insulation and fire resistance. If you are not sure whether a particular material contains asbestos, you might ask a heating specialist or a plumber or have the hot water system inspected by a professional asbestos inspector.
2. Resilient Floor Tiles. If your house has the original vinyl, asphalt or rubber floor tiles, there might be asbestos in the tiles and in the adhesives underneath the tiles. As long as the tiles are in good condition, they will not release asbestos fibers. If you decide to remove any older tiles, make sure not to sand or scrape them, as this might release microscopic asbestos fibers into the air. It is always best to use professionals to remove any suspected asbestos from your home.
3. Textured Wall Paint and Decorative Wall Finishes. Until 1977, many brands of textured wall paint and spray finishes were made with asbestos for enhanced strength and durability. Since finding asbestos fibers in the wall paint requires a special type of microscope, you should have professionals inspect your walls to make sure they do not contain any harmful substances.
4. Older Cement Roofing, Shingles and Siding. While the roof of your home might look just fine, it might contain asbestos materials. Asbestos cement used to be a very popular material for manufacturing and installing various types of roofing. Fortunately, roofing materials do not release asbestos fibers unless disturbed by sawing, drilling or cutting. However, you should regularly inspect your roof for any loose shingles and peeling roof felt to avoid release of asbestos fibers.
5. Wood Burning Stoves. If your house has an old wood burning stove, there might be asbestos fibers in the wall and floor covering around the stove. Generally, the coverings will not release asbestos into the air as long as they remain in good condition. However, to be safe, you might want the old wood burning stove examined professionally and any asbestos removed.
Exposure to even a very small amount of asbestos can lead to illnesses such as malignant mesothelioma. A mesothelioma diagnosis can be devastating, as most patients succumb to the illness in less than one year, often leaving family members with a financial burden in addition to their grief. It is important to rely on professionals to handle asbestos removal from the home. In addition, in case of a mesothelioma diagnosis, it may be useful to consult an attorney regarding your legal options.

The dangers of asbestos


The dangers of asbestos have been known for a very long time and even the companies that made billions off of asbestos products have long since given up defending the virtues of asbestos. Unfortunately, there were way too many years between identifying the dangers of asbestos and getting asbestos pulled off the market but finally new asbestos products have been almost universally banned.

The biggest problem with asbestos today is dealing with the past. People still suffer from mesothelioma and other respiratory problems caused by asbestos. Perhaps an even bigger problem is how to deal with the asbestos that is still out there in older buildings, concrete and insulation. For more than half of the 20th century asbestos was used just about anywhere that required insulation. It was just about everywhere out there - and still is.

Of course the public outcry against asbestos called for the immediate removal of all asbestos anywhere people were exposed to the hazard. However, this is often easier said than done. In all too many cases the biggest expense involved in renovating an older building is dealing with asbestos. Often the expense of totally removing asbestos has prevented renovation of older buildings. Demolishing or renovating old buildings used to be easy but not anymore.

For many years asbestos removal was at a stand still. Those companies that could afford to remove asbestos insulation in their buildings had already done so; often at great expense. Those companies with smaller financial resources usually just left their old buildings alone and delayed dealing with the asbestos. Finally in the 1990s governments started to approve alternate ways of dealing with asbestos in buildings.

Currently there are 3 approved ways of dealing with asbestos in older buildings. Removal is still the preferred way, but is very expensive and not entirely without dangers. Simply getting the asbestos out exposes it to people. The trick and expense in asbestos removal is keeping it out of the air and away from people. An additional problem with asbestos removal is you have to install new insulation and fireproofing, usually fiberglass, to replace the asbestos you are removing.

A second way of dealing with asbestos is called encapsulation. This involves actually building a structure around the asbestos so that it is totally contained. In some cases this is a viable option but usually it is almost as expensive as removal. Many buildings cannot handle the extra weight of the encapsulation structure.

The third way of dealing with asbestos is called encasement. With this procedure a special 2-part coating is sprayed over the asbestos totally preventing exposure to the fibers. The first coat is a primer that binds with the asbestos fibers, holds them in place and also prepares the surface for the second coat. The second coat is the sealer that does just that, totally sealing off the asbestos.

Independent testing of encasement has shown that the final surface is completely safe. There are no airborne fibers or other volatile substances coming off the surface. It is totally harmless. In the field, encasement has proven to be more than 50 percent less expensive compared to removal and can be done in half the time and with much less labor expense. The big drawback with encasement is the asbestos is still there but as long as the building isn't changed or demolished the encasement coating renders the asbestos totally harmless.

People turned to asbestos


While many people know of the connection between asbestos exposure and lung cancer, you may not realize that ingesting or inhaling asbestos has also been linked to kidney, or renal, cancer. The American Cancer Society estimates that 12,980 Americans die of renal cancer each year. Although you cannot protect yourself from everything that may cause kidney cancer, you can avoid asbestos to minimize that risk factor.

As well as asbestos, there are other risk factors that can increase your chance of developing kidney cancer. Other workplace hazards include cadmium, benzene, trichloroethylene, and some herbicides. Additionally, smoking and suffering from obesity can also increase your risk. Interestingly, however, the rates of kidney cancer have been rising since the 1970s. While this could be attributed to better cancer detection techniques, it could also be that people who were exposed to asbestos before it was banned are now developing this type of cancer.

The problem with asbestos is that it was a very popular material before doctors realized the dangers of the fibers. Although even the ancient Greek and Roman cultures utilized asbestos, it did not become widely-used until the Industrial Revolution. During that time, people noted the need for insulating materials for the engines and piping now in place in buildings and ships.

Why People turned to asbestos ?

People turned to asbestos because it has amazing insulating abilities. Asbestos is part of the silicate family of minerals. Silicates are known for their ability to resist heat, flame, chemicals, and biodegradation. Besides these useful characteristics, asbestos was also helpful because it has high tensile strength and flexibility.

Due to these helpful properties, it is no surprise that asbestos became a staple for construction, automotive, shipping, and other industries. In building construction alone, asbestos could be found in the insulation, vinyl flooring, counter tops, roofing tar, and roofing tiles. Ships were built using asbestos insulation as well. Lastly, the automotive industry utilized this material for brake pads, brake shoes, clutch pads, and gaskets.

Asbestos can cause renal cancer because your body is unable to process the fibers. When asbestos particles are released into the air or water, you can inhale or ingest the fibers. Once in your body, they can become lodged in your organs or cycle around the bloodstream since your body cannot break them down. If they are in the blood, they can get caught in the filtering area of the kidneys. From here, they can become stuck in the kidneys and cause malignant tumors.

Kidney cancer can be especially dangerous because it is so close to the bloodstream. If the tumor in the kidney is malignant, it can break off and flow through the blood to another part of the body.

If you or someone you know has developed kidney cancer due to asbestos exposure, you should speak to an asbestos attorney about your options.

Good insulation results in less energy costs

Insulation in your home is something that many take for granted. Good insulation results in less energy costs. A problem is that many homes have were vermiculite insulation containing hazardous asbestos fibers.

How Do I Know if I Have Vermiculite Insulation? 

Luckily, vermiculite insulation is often easy to recognize because its appearance resembles small pebbles that are grey, brown, silver or gold. It was a very popular form of insulation used in homes and buildings over the course of many years. If you look at your insulation (but do not disturb it or move it) and it appears to look like small pebbles, it may be contaminated with asbestos. Do not attempt to remove it yourself.

Asbestos is dangerous and toxic when it is disturbed, so the last thing that you want to do is head to your attic and begin pulling the insulation down as doing so will release the fibers that can put you and your family at risk for cancer, respiratory diseases and heart problems. If you see the vermiculite insulation in your attic, it may also be in your walls. Again, do not begin tearing down your walls or, in any way try removing the insulation without guidance from a professional.

Is My Family as Risk if We Just Leave the Insulation? 

As long as you do not disturb the insulation you and your family may be safe. When the asbestos is moved around (disturbed) it begins releasing harmful and toxic chemicals that are dangerous when inhaled.

If you need to go into your attic, be sure to wear protective gloves and a mask just in case you accidentally move any of the insulation. If your attic has a lot of the vermiculite insulation, it is probably best not to store anything in the attic or to have it professionally cleaned by an asbestos removal professional.

What if I Want to Remodel My Home? 

If you are planning to remodel, you will need to hire a professional because he or she may know how you can do the remodeling without having to move the insulation.

What if I Have Been Exposed? 

If you have disturbed some of the vermiculite insulation in your home or have torn down a wall in your home, you may want to consider having the remaining insulation in your home tested for the presence of asbestos. You and your family will need to be regularly tested for asbestos-related illnesses if the insulation tests positive for asbestos.

Final Thoughts 

While some people assume that it is better to remove asbestos insulation if it exists in their homes, new research has found that leaving it alone undisturbed is the best defense. Even if you have to remodel, there are ways to do so to prevent the disturbance of the asbestos contaminated insulation. Always consult a professional before making any decisions.

Don’t try to remove asbestos insulation by yourself

Asbestos is a naturally occurring, fibrous mineral with very remarkable qualities: it can effectively resist heat, steam, and fire. These qualities make asbestos an ideal material for insulation, which were used to line roofs, ceilings, attics, and walls of both houses and buildings. The type of insulation was widely used in residential, public, and commercial buildings before the 1980's.


Despite its excellent qualities that made it an ideal ingredient for construction materials, asbestos is highly hazardous to both the health of humans and animals. Asbestos consists of several silicate minerals that can be separated into fibers and particles easily. When inhaled and ingested, these particles and fibers can cause a variety of pulmonary diseases, including asbestos poisoning (a scarring of the lung tissues caused by sharp asbestos fibers and will cause chest pains, shortness of breath, and dry coughing), mesothelioma (a cancer unique to asbestos exposure-and an extremely fatal one), and several kinds of cancer that will affect the lungs, stomach, larynx, esophagus, and even the kidneys.

Asbestos insulation is a problem that plagues a lot of homeowners and property owners. Action should be immediately taken, because the risks of the diseases mentioned above will increase when exposure is prolonged. How will you know if your insulation uses asbestos? Here are a few things to watch out for:

  • It is important for you to know the exact date when the house or building you are living in is constructed. If it was built before the 1960's, there is a high chance that the insulation material lining the walls, attic, and roofs.
  • Check if the insulation used in your house or building is of the loose or batted type. These kinds of insulation material will look life fluffy, grayish clumps of fibers and they are often found between the rafters.
  • If your home has a lot of old pipes, check if they are covered with a blanket-like material in the elbow joints and valves-these are insulation materials that contain asbestos. There are also asbestos insulation materials that look like cardboard coverings-and this was especially popular in steam heating pipes manufactured in the 1910's to the 1980's.
If you suspect that the insulation materials in your home or building contain asbestos, you should treat them as though they really contain asbestos. This means avoiding contact or exposure to them, and immediately calling a professional asbestos remover to inspect them. Asbestos can only be positively identified by using polarizing light microscopy, which can be found in laboratories certified by the Environmental Protection Agency.

You should not try to remove asbestos insulation by yourself, even if you wear something over your nose to provide protection from inhaling the fibers. Licensed professionals use special masks and gloves to handle the asbestos materials, and they possess the technical knowledge to safely extract these materials from your home. They also use special equipment to isolate and seal off the infected area, and initiate decontamination once the job is done.

How to Clean Asbestos Dust

Asbestos is a substance that is present in many different kinds of products. You can find asbestos fibers mainly in insulation, certain cements and floor tiles, and some kinds of paint. When asbestos is in these types of products, they are usually harmless. Asbestos can be very harmful, however, if it is inhaled or ingested, which is common in many types of renovation or construction, as well as the cleanup from natural disasters. You can find more information about asbestos at the website under the additional resources. If you find that your home has been exposed to asbestos dust, it is important to get a professional service to clean up as much as possible before you try to clean up anything else.

Put on your mask and protective clothing. Seal any joining areas with duct tape to avoid air exposure.

Wipe all exposed areas with the wet rags. This will help keep the dust from spreading as you clean.

Clean all furniture and carpets thoroughly. You may want to make several passes to ensure that you get the deep down dust, especially in the carpeting; vacuum them several times to make sure that you have gotten all the small particles.

Clean hard surfaces with regular cleaners, using rags that can be disposed of properly.

Contact an agency to test your home. After you have cleaned everything, it is important to have the home tested to make sure there are no lingering asbestos fibers.
