When animals like bats, raccoons, roof rats, and common or flying squirrels get into an attic, they contaminate the insulation with urine, feces, shed fur, parasites and other contaminants. Unless removed, these disease-causing contaminants will remain in your home's insulation literally forever, creating an unhealthful condition that remains long after the animals are gone.
Disease-causing organisms associated with animal wastes can get into the living area of a house by riding air currents, or they can literally be pumped throughout a house that has hot-air heat or central air conditioning. Not only does this create an unhealthy situation, but the odors left behind from animal wastes and other by-products this can actually attract other animals (as well as insect pests) to the attic.
That's why a complete animal removal job sometimes includes removing and replacing any contaminated insulation. If animals have been in your attic for an extended period of time, the chances are that they've made a real mess of your insulation, and it most likely will need to be replaced.
After animal waste remediation has been accomplished, applying new insulation to the, sanitized attic, crawl space or walls is the final step of the waste remediation process.
One of the most cost-effective ways to make your home more comfortable year-round is to add insulation to your attic. At times our wildlife inspectors frequently find that many homes were under-insulated since the time of construction. No matter what kind of insulation you currently have in your attic, one quick way to determine if you need more is to look across the span of your attic. If your insulation is just level with or below your floor joists (i.e., you can easily see your joists), you should add more. If you cannot see any of the floor joists because the insulation is well above them, you probably have enough. It is important that the insulation be evenly distributed with no low spots; sometimes there is enough insulation in the middle of the attic and very little along the eaves.
Adding insulation to your home is a great way to increase the comfort of your living environment. Adding home insulation to an existing home will regulate the temperature, making your living environment more enjoyable, especially in places of extreme weather. Insulating your home also has cost benefits to you as homeowner. With added insulation your home will become much more energy efficient.
Another benefit of insulating your home is a reduced environmental impact. With an insulated home you will be using less energy for heating and cooling your home. This will reduce your carbon footprint, and also reduce the amount of chemicals released into the environment from air conditioning units.
