investigation it was coming from a small closet that has a sink and big pipe (which may be a sewage pump ejector, I'm not exactly sure) running from the upper floor to the ground. I have never noticed this smell before. I think it had rained the day that happened.

Again, today, the smell came back but it smells more like sewage. We do have a septic tank, and we had issues with it leaking into our lawn a few years ago and we got the entire tank replaced I believe.

Any tips? Is this smell dangerous (eg methane buildup) or is it harmless and disgusting?

proof(specially the ceiling and stair well area. So should I do something like a rigid blue on the concrete area?, just do a good pink R30 something, moisture barrier, spray foam, wedges any ideals?

owners before be put in the garage door and track. My problem is the door is not sealed up just right. I can see daylight almost all the way around mainly on the bottom, and the sides and top, as seen in the pictures are, only sealed by the white rubber door seal. What can i do to seal this up better to help keep it warmer when i am working in it?

Our basement is probably 1,500 sq ft and I already have a wish list... Office/Scrapbooking room, Playroom/Lounge Area, Dance/Exercise Room, Bathroom, etc. The bathroom is roughed-in, but other than that it's just concrete floors and walls. Should I get a Designer/Architect to make the most of the space I want to create and get the decor I want? If I do that is it going to cost an outrageous amount? Any and all advice is much appreciated!

completely full of silt and mud. Water that collects at the bottom of the stairs eventually drains out (over a period of days) but a heavy rain will quickly overwhelm the area, and water comes in under the basement door.

I haven't been able to pry the drainplate off, but could probably chip out enough concrete to do that if I thought I could get the muck out of the well by removing it.

Covering the basement stairs is a possibility, but not an easy one in this case.

Any suggestions?
