Got That Bad Odor

The nuisance aroma associated with today’s home environment is complex, confusing, and almost always unhealthy. The issues that drive bad odor are often elusive, surprising, and difficult to address because it’s often the result of several seemingly insignificant causes.

Building materials absorb and re-release odors differently; soil gases come and go; ambient impacts (pets, occupants, lifestyles, etc) are ever-changing where we all just smell things differently. One thing is for sure; if that odor came from the leftovers in your refrigerator you probably wouldn’t eat it. So what makes it ok to breathe it.

Odor Categories

We like to break the odor down into a base category: Chemical (paint / new car smell / VOC), Organic (insect / animal / rodent / sewer / essential oils) or Biological (bacteria / yeast / fungus / mildew / virus). This is how we start designing a testing protocol to pinpoint the odorous source.

Where’s That Smell Coming From?

Bad Odor can be hard to pinpoint an exact location. They can become hidden in dead air spaces, bound up in building materials or saturating softer materials. They often come and go tied to the structures changing ventilation or due to environmental conditions tied to Temperature, Pressure, and Humidity. But the CDC can help with overall Environmental Odors to help narrow possible sources of the odor.

There’s Always a Pattern

The smell may come and go, be intermittent/constant, maybe location-specific, or revolve around outside issues like temperature, pressure & humidity. It might be associated with turning the Air Conditioner on or recent home improvements (new windows, siding, painting, roof). But there is always a pattern that once identified is crucial in designing an appropriate remedy.

What Can I Do Right Now?

If you can’t identify the cause or “Migration Pathway” it is important to bring in a professional to conduct an “assessment”. But there are some steps you can take yourself.

Fresh Air Movement

Open windows, cross ventilation, exhaust fan are good steps. Turning the furnace blower to “on” instead of “auto” will move air.

HEPA/Charcoal Filters

Work well on particulate based odors like mold, cigarette smoke, dust, pollen & allergens, and chemicals. Use in the furnace and monitor results.

Avoid Ozone

Ozone producing filters can have serious health issues. Best to avoid them if at all possible.

Focus on One Room

If the odor is throughout the home, take the bedroom and make it a “clean room” environment so you can at least get a good night’s sleep.

Remove Items That Can Hold Odors

Papers, stuffed animals, stored clothes, etc. These items can hold allergens and bad odors like a sponge.

Try Odor Eliminating Sprays

There are chemicals that can neutralize odors but use sparingly on test areas as may create additional problems.

Getting Help – Identification & Correction

There are environmental professionals that specialize in odor identification. But they are hard to find.  Typically these “Building Biologists” are familiar with both chemical, biological, organic, and particulate air contaminates. They generally have an understanding of building design, construction/trade practices, HVAC systems, hydrology, and a solid understanding of the surrounding natural environment (.

Finding someone to fix the odor problem can be even tougher. Firms that do both are often the best bet as every odor problem is unique requiring expertise across the board. Like a good mechanic who diagnoses why your “check engine light” won’t go off. He’s often the best guy to then fix it. It all boils down to trust so don’t feel pressured.

What Does It Smell Like?

This open pit is where the sewer line exits the home. A leak in the water line keeps the pit nice and juicy. A crawl space full of raccoon feces provides nutrients for that glob of nasty biofilm and the open pipe allows sewer gases to back up into the home. The odor is nasty and migrates up into the home. The moisture contributes to molds on the floor decking overhead. You gotta smell this!
