HELP, Humidity is below 50% but my basement still has a smell

Pauly78July 10, 2013

We bought a house with a finished basement last year. The humidity was off the charts (67%) and bought a dehumidifier a month ago. It works well and the humidity holds between 46 and 50%. However, I still have a smell. How do I get my the place to smell just like upstairs? I want to be able to open the door to the basement and not notice an immediate difference in smell. Can this be done, or is there only so much you can do with a basement? I should also mention that I ripped up the carpet last year, as I thought some of the smell might be trapped in there. The only thing left is the sheetrock and ceiling tiles. Thanks for any advice.

The only thing left is the sheetrock and ceiling tiles.

...and the wood framing behind the drywall.

Unfortunately, once a basement has been a mould farm for years, often there's not much you can do but remove everything and start over.

First, though, be sure the odour is mould, not sewer gas from a dried-out floor drain or improperly vented bathroom or kitchen fixture.

As part of mold testing I do and the least invasive way of checking for moisture issues is to use a IR Thermometer which will use a laser pointer to highlight an area I know Harbor Frieght has inexpensive version if there is a store in you area.

Point at different areas of wall and cielings etc and the areas with moisture problems will show a few degrees cooler temperature then the other similar surfaces.

I would do this after doing as worthy suggested pour some water in your floor drain to make sure the P trap is full so sewer gas is not from the drain.

Here is good link to mold questions and answers.

Good luck,
