Insulation, especially in areas such as attics and basements that has been subjected to constant leaks may be damaged after a period of time. This increases chances of mold and mildew formation that may spread to other parts of the building. Small animals such as mice, squirrels and bats may also find their way into damaged insulation, contaminating the material as well as causing damage by nibbling and scratching. All of these combined heighten the risks for disease among the people inside, thus the need for removal.
Over insulation happens when the owners or builders got a bit too carried away during installation, placing too-thick layers that tamper with indoor ventilation. This in itself is inefficient insulation, as bulky materials also create unwanted air pockets that negate the point of an airtight building. There are cases as well when insulating material comes in contact with electrical wires or downlights. When this happens, there are increased fire risks.
Insulation removal is further needed to protect owners' insurance. Insurance companies don't usually pay out for ceiling collapses that haven't been tampered by outside forces. This means negligence on the maintenance of the structure. Of course, removal is also done during renovations and when an owner just wants to upgrade the insulating system to a better one.
There are several agencies or companies that offer insulation removal. This job often requires professional services, as insulation removal is neither an easy nor a safe DIY task. There are chances that a person might get contaminated by whatever is inside the old insulation, or manage to have everything cave in suddenly. Companies use high-powered vacuums and other equipment not just for removal, but to clean the vacant space as well. They make sure to transport and get rid of the old, dirty material in a way that will not endanger anybody. These insulation removal companies are capable of taking out any kind of insulating material used, from fiberglass boards to sprayed-on foam.
Protection from anything that may be a hazard to life and limb should always come first. So for those with questionable insulation in their homes or buildings, have it checked and if recommended, get someone to perform insulation removal. This way, everything and everyone continues to enjoy a comfortable, healthy environment.
