Know What You Want
Deciding What You Want from Asbestos Removal Companies in Contra Costa County

  • Do I want a Diamond Certified asbestos remediation service that is rated best in quality and backed by the Diamond Certified Performance Guarantee?
  • What is my timeline for the removal of the asbestos?
  • How much can I budget for asbestos removal?
  • What personal and professional characteristics would I like my Contra Costa County asbestos removal company to have such as good communication skills, timeliness, honesty, integrity, and reliability?

  • How To Work With
    Now that You've Found an Asbestos Removal Company in Contra Costa County

    Asbestos removal does not have to be a major financial setback. Plan your budget and stick to it. After you have found a Contra Costa County asbestos removal company in Contra Costa County that you can trust, you will have peace of mind having your asbestos removed.

    When you meet with the contractor, use the notes that you have taken so you can accurately describe any concerns that you have. Be as detailed as possible and don’t be in a rush. It is as important for you to hear their suggestions and observations as it is for them to hear you. If you don’t understand something, ask for an explanation. You need to completely comprehend the plan and any problems or solutions.

    Be sure to get all estimates in writing before any work begins. The estimate should include an itemized list of the cost of supplies and the labor. Don’t ever sign a blank estimate.

    Signing the Contract with Contra Costa County Asbestos Removal Services You Trust
    When you feel satisfied with the information you have received from your Contra Costa County asbestos removal company, sign the contract. Be sure that they have a phone number where you can be reached at all times.

    Expect the contractor to stay within the estimate. However, if the actual asbestos removal costs exceed the original amount of the estimate, the asbestos removal company must get your approval before moving ahead.

    Ways to Make the Work Easier for Your Asbestos Removal Company
    Professional asbestos removal companies are able to handle the very small to very large aspects of their work. However, there are some things that you can do to prepare for them and to make their progress in removing your asbestos go more smoothly and more quickly. Doing these things may even cut down on their labor costs and can keep your home and belongings from being damaged.

    Remove any furniture or movable items from the area where they will be working. The more you do the more quickly they can get to work.

    Keep your pets and children away from the area. Your asbestos removal company will be focused on removing the asbestos and should not have to watch out for your pets or children at any time. This not only prevents accidents and injury but also any expense that comes from accidents that may happen because of children and pets being in the way.

    Trim plants and bushes that are in the way of the asbestos removal area. You can save money and time by preparing the area for building by trimming or removing any plants, trees or bushes that are in the way. Ask your contractor what they recommend and the amount of space they require.

    Provide parking space and room for their work vehicles to maneuver. Some asbestos removal companies have large vehicles that require more space than average. Contact your contractor before they begin and ask them how many parking spaces they need and how much room they need for oversized vehicles. It is also helpful to walk through the area with your contractor so any hazards or clearance issues can be pointed out before the asbestos removal.

Q: What are the health problems related to asbestos?
A: Asbestos can cause cancer. This cancer is called mesothelioma and it affects the pleura, peritoneum or the pericardium. It also causes asbestosis which is a scarring of the lungs.

Q: Where does one find asbestos?

A: Asbestos is a naturally occurring substance and is found in the ground. It is actually being mined currently in other parts of the world including Russia and Canada. It was used for insulation products and other products that were fire resistant.

Q: Who is at risk for developing health related problem to asbestos?
A: Those that are at highest risk are those who work in industries that use asbestos on a regular basis. Shipbuilding and construction are 2 of those industries. Also, if you have mined asbestos, you are at higher risk.

Q: How do I identify asbestos?
A: You probably cannot identify asbestos just by looking at it. Asbestos fibers are long and rather like needles. Asbestos is often mixed with other materials which makes it more difficult to identify. The best way to know if your home has asbestos is to hire an asbestos removal company to survey your home. Asbestos is best dealt with by professionals.

Q: Is asbestos considered dangerous?
A: Asbestos can be dangerous especially if there is long term exposure, if it has been damaged or if it is deteriorating. Old asbestos can break apart and become airborne. When asbestos fibers are airborne, they can be inhaled and cause damage to the lungs and other areas of the body. Asbestos can cause a type of cancer called mesothelioma as well as other lung scarring and problems.

Q: How does a physician diagnose if I have been exposed to asbestos?
A: There is no test to determine if you have been exposed to asbestos. The most common way to check for exposure is to look for disease by having a chest x-ray. A physician may also give you a pulmonary function test which determines your lung capacity. If there has been a decrease in lung capacity or the x-rays show early signs of lung disease, then they may determine that you have had exposure to asbestos.If you know that you have been exposed, you may want to have regular physical examinations by a physician. The risk of developing disease is related to the frequency and length of your exposure to asbestos. Smoking cigarettes can also increase your risk of developing asbestos related diseases.

Q: If I know that I have asbestos in my house, is it absolutely necessary for me to have it removed?
A: You need to have an asbestos removal company do a test to check for asbestos. Most of the time it does not need to be removed but only an asbestos removal company can tell you that. Often the asbestos is in tile, siding or roofing. These materials don’t usually break down so an asbestos removal company will, more than likely, determine that this doesn’t need to be removed. However, if asbestos is found in an area that may be disturbed, you will want to schedule asbestos removal.

Q: Which type of asbestos is the most dangerous?
A: Crocidolite has caused more cases of mesothelioma than other types of asbestos. Most asbestos comes from the type Amphiboles. It seems that Chrysolite, which is different than Amphiboles, has fewer risks and less disease associated with it. However, any kind of asbestos carries risks associated with it.
