After the big rains recently, all of sudden, we smell the "earth smell" from the craw space in many rooms of the house, especially the ones with hardwood floor. Not sure it was due to the water accumulation in craw space or other reasons. We like to have the fix ASAP. Please contact me immediately if all possible. Thanks!

We are in the midst of a residential remodel in Palo Alto. Water continues to puddle and 'pond' up under the house and our contractor has recommended that we look into installation of a sump pump station and/or crawl space encapsulation. In the past we have used a sump pump to remove water from under the house. With this year's heavy rains it's clear that we need stronger measures to maintain proper drainage.

There is an odor coming from the floor which I'd like to eliminate. I suspect the odor comes from the crawl space. Thanks.
