Odors can come from a variety of sources:
- Smoke odors from a fireplace fire that got a little out of control can leave a powerful charred smell. Cooking fires caused by leaving something in the oven too long or oil that splashes in a frying pan can fill the kitchen and surrounding rooms with a white protein smoke. Even scented candles left burning too long can leave an over-powering odor.
- Water damage odors generally have a mildew smell from wet building contents. And the longer a structure is exposed to moisture, the more powerful the odor becomes. Water damage situations such as toilet overflows or sewage backups only compound the odor problem.
- Animal odors can range in severity and causes as well. From skunk spray to urine and feces, these odors can penetrate deep into fabrics, walls, carpet, and sub-floors. Animal odors include carrion odors (dead body), such as those caused by an animal that dies in the attic or crawlspace and goes undetected for a long period of time.
- Tobacco smoke odors caused by people smoking cigarettes, cigars, or pipes indoors tend to permeate the entire structure. The longer a person smokes inside, the stronger the odor is and the more difficult it becomes to remove.
