Molds are tiny spores that float through the air continually. When mold spores land on a damp spot indoors, they may begin to grow.
Molds can grow almost anywhere, among them, on wood, paper, carpet, foods, etc. When excessive moisture accumulates indoors, mold growth will often occur. In order to control mold growth, one must control moisture.
Things To Know About Mold:
- Mold can be hazardous to health. Symptoms associated with mold exposures include, allergic reactions, asthma, and other respiratory issues.
- There is no practical way to eliminate all molds in the indoor environment.
- If mold is a problem, you must clean up the mold and eliminate the source of moisture.
- Reduce indoor humidity (to 30-60%). By venting: bathrooms, dryers, and other moisture-generating sources to the outside by using air conditioners, de-humidifiers, exhaust fans whenever cooking, dish washing and cleaning will decrease mold growth.
- Clean and dry any damp or wet building materials and furnishings within 24 - 48 hours.
- Clean mold off hard surfaces with water and detergent and dry completely.
- Leaky plumbing and other sources of water should be repaired and eliminated.
- Absorbent materials (such as ceiling tiles and carpet) that become moldy have to be replaced.
- Reduce the potential for condensation on cold surfaces (i.e. windows and piping).
- In areas where there is a perpetual moisture problem, do not install carpeting

Asbestos is a mineral which is mined for its useful properties like, thermal insulation, fire proofing and other building materials, such as, cement wall boards, vinyl floor tiles, pipe and ducts wrappings, etc.
Asbestos is made up of microscopic bundles of fibres, that may become airborne when asbestos containing materials are damaged or disturbed. When these airborne fibres are inhaled into the lungs, they can cause heath problems.
Asbestos can be found in materials in homes built before the 1970s. Some places where it may be found include roofing, shingles, and siding; however, these areas will not release dangerous asbestos unless they are cut into. Asbestos also may be found in certain types of floor tiles or vinyl flooring. Again, asbestos will only be released if the tiles are sanded or scraped during floor removal.

Vermiculite is a naturally occurring mineral that has the unusual property of expanding into worm-like shaped pieces when heated. The expanded vermiculite is lightweight and fire resistant, which is used in numerous products, including attic insulation.
Much of the world's supply of vermiculite came from a mine in Montana.U.S. before it was closed in 1990. Because this mine had a natural deposit of asbestos, the vermiculite collected from the mine was contaminated. Therefore some vermiculite insulated attics may contain asbestos fibres.
Vermiculite attic insulation is a pebble-like, pour in product and is usually light brown or gold in colour, with a metallic sheen. It is difficult to determine if an attic insulated with vermiculite is contaminated or not, unless checked by a specialist.Therefore to be safe, it's better not to disturb it. Any disturbance has the potential to release fibres into the air. Entering the attic should be limited. no storage of boxes in the attic. No attempt should be done by an untrained person to remove it.

Radon is a radioactive gas which exists naturally in the soil, rock and water. It forms by breakdown of uranium in the soil and naturally escapes into the air, and when it accumolates in high levels inside a home, it is a concern to health.The known risk associated with exposure to radon, is increasd risk of developing lung cancer.
Radon can enter a home through any openings, where the house contacts the soil, such as exposed soil in a basement or crawlspace, cracks in foundations, cracks in floors and openings around pipes entering the house.
