Question DetailsAsked on 5/28/2014

what kind of company finds and eliminates odors in a house

We live on the SE side of Indianapolis. Recently we've had a acrid odor that seems to be coming from our basement. I've used a black light to see if our cat may have urinated on the carpet down there, but didn't find anything. My sister said it smells like a mold or mildew odor. I don't know what it is, I just want it gone. Please help!

If mold smell, there are commercial mold remediation companies. Just bear in mind that anyone can do a mold test and show you there is mold in your home - mold spores are everywhere in the air, that does not mean they have to have anything done about them, if they are not actively growing and spreading on some surface.

By yourself, you can check (using bright lighting) all walls, ceiling, exposed undersides of overhead floor and suspended piping, and floors for any signs of water staining, dampness, or mold or mildew growth, or standing water. Check especially around HVAC equipment (mold grows nicely on A/C evaporators in central heating systems), standing water in pans under evaporators/dehumidifiers, sump pump sumps, etc.

If you are able to, peel back carpets around edges and look for mold on the back, or staining on the concrete slab indicating water intrusion through the foundation or up from below the slab.

Basically, if it was cat urination it will dry in a couple of days or less, or become a regular use spot and become overpoweringly acidic smelling and unmistakeable.

Common sources of moisture and associated smells in basements include leaking pipes in overhead joist spaces, leaking boiler or water heater, outside runoff water coming over or through basement foundation, seepage or water vapor passage from moist ground up through basement concrete slab (which rarely molds by itself, but molds flooring or walls it comes in contact with), and stagnant sump pump pits.

Commonly, though it might be embarrassing, getting a few friends or neighbors you are friendly with to smell it and tell you might help a lot - mildew, mold, animal leavings, oil heating leaks, and boiler leaks commonly smell very different and many people have experience with some or all of them - that can help a lot in identifying the likely source.
