Home odor troubleshooting, without the guesswork

Find the source. Know the risk. Fix the smell.

Use five real clues — location, odor, timing, pattern and warning signs. SmellFixer ranks plausible pathways, explains the fit and gives the next check instead of handing you a generic answer.

What smells wrong?

Work through the evidence. The finder can interrupt the normal flow for gas, fire/electrical and CO warning signs, then otherwise ranks the closest source pathways and tells you what would change the ranking.
