How long before the smell leaves a house? Had some pipe replaced two days ago under our house in our crawl space. The smell seems to have faded in one area but now stronger in another. We expected the smell to be gone by now.

This could be one of many things.

- It's possible the contractor removed old pipes and didn't dispose of them properly,

- Sewage from old pipes could have leaked onto an area and still remains there.

- connection may not be fully sealed.

- vent may not be connected to anything or a AAV may have been used.

The smell from open pipes usually dissipates after a few hours of windows/doors open.

Josh is right with his suggestions.

It can be difficult to locate a sewer smell sometimes.

How old is your house?

What kind of piping do you have throughout it?

Do you have any floor drains? etc, etc,

Ultimately the only way to say for sure is to be on site to investigate.

Hope this helps!

They may have left the old pipes under the crawl space leaving the smell or there is still an issue with the plumbing and it wasn't fixed 100%. What kind of piping is it? If there is old pipes under the crawl space still full of material the smell won't go away.

Thank you so much for the feedback. The company removed the old pipes. Our crawl space is dirt and of course the sewage was seeping into it 4 feet down to the break. I'm assuming when they dug and disturbed the soil it's now all over the crawl space and the smell is lingering. I was curious how long the smell would typically take to disappear.
