"Lesson learned. Always get an estimate. BEFORE the work is done. At least a digital copy. Arrangements for the project were made, with some one named Lynn, for the company to send someone to complete the work. We were quoted over the phone 4500-5000 which included a mold test. A sub contractor with an entirely different company (National Mold Company) was sent. When the contractor arrived, he stated that the job would be much more simpler than first thought. This led us to believe that the job would cost less, no. All said and done, they charged $5500. All said and done, it's almost like no work was done. The stains and the smell are still there. Only one actual board was taken upon the attic room. The ceiling in the bedroom was primed and painted but are still visible and have a funky smell. At this point I'm going to. Do what we should have done; Do the job ourselves. Just now with $5500 less dollars in our pockets. A detailed receipt was not given even though it was requested."

Mold Testing and Remediation questions, answered by experts

Sewer gas in any location can cause eye and respiratory irritation if you’re exposed at low levels, or more severe symptoms if you’re exposed at high levels—but fortunately, the fresh air outside means it’s less likely to affect your physical health. However, sewer smells outside can still indicate significant plumbing problems that will need to be dealt with, such as a potentially damaged sewer line or roof vent pipe.

If you see mold spores on walls, flooring, or ceilings, it’s best to call in a mold inspection pro to investigate. Similarly, if you smell signs of mold—musty, earthy, rotting wood, or stale scents—it’s time to call a mold inspection professional. 

Other less-obvious times when you should have your home inspected for mold include:

  • After flooding

  • After home water damage

  • Having ceiling or wall damage

  • Buying or selling a home

  • After a persistent unexplained cough or allergy symptoms 

  • Noticing discolored surfaces

Mold doesn’t take long to form, especially in dark, isolated areas like under the floorboards, where you’re less likely to know it’s wet in the first place. Mold can take root and proliferate in just 24 to 48 hours, but it can be up to a week before you start to notice funky smells. 

Several factors affect the color of mold, including humidity levels, age of the mold, and amount of light it receives. A patch of mold that starts out green may darken and turn black as it ages. A species of mold may be green if growing in one environment, but be black in another environment. Color usually isn't a reliable way to determine mold species or risk.

Symptoms of sewer gas poisoning include nausea, dizziness, extreme drowsiness, and headaches, according to the Wisconsin Department of Health Services. Exposure to higher concentrations for long periods of time could also lead to unconsciousness due to a lack of oxygen, aka suffocation. If you think you’ve been exposed to sewer gas for a dangerous amount of time, seek medical care immediately. Do not return to the site of exposure, after you’ve received medical care, call a pro for help.
