Hello, Our sump pump in the crawl space seems to stop working. Thanks.
Project Location: Moraga, CA
We noticed puddles of water in crawl space in this raining season. So we are seeking a solution to remove the water
Project Location: Moraga, CA
We would like to have a sump pump installed in our crawl space under the house. Last winter during the heavy rains, we had flooding under the house. The insulation around the heater ducts got wet and pulled down one of the ducts, resulting in water getting into the heater ductwork. Consequently, we had to replace all of the ducts.

Dampness in crawl space

2" standing water in crawl space -can't get to disconnected duct because of that
Project Location: Moraga, CA
We are currently getting a lot of leaking in our crawl space during rain storms. We have a small sump pump but it is not working well, and we end up with standing water and a damp odor and it is impacting our bedroom areas. We'd like to look at improving the drainage as well as installing a vapor barrier to improve the situation. I look forward t hearing from you.

Moisture under crawl space, earth odor after recent rains
Project Location: Moraga, CA
After the large rainstorm, I am concerned that my crawl space may have received too much moisture. I would like it to be inspected and remedied if needed.
Project Location: Moraga, CA
We live in MCC in a townhouse with a crawl space under the house. I believe what we have now is a sump pump and just ventilation for moisture control. The vents to the house allow air from the crawl space into the house- which is partly my concern. When it rains hard (like this week) it makes the house smell very musty. My husband's thought is this is a nonissue most of the year with such drought conditions except for when there is a torrential rain storm, which is why we've not yet done encapsulation. I've read about all the possible resulting issues from moisture left unmanaged in the crawl space and perhaps temperature large variances may cause condensation in the cold ground under the house. Since it's MCC we have little control over drainage issues as the club manages that. Ultimately we would like to know if crawl space encapsulation is necessary and how costly it would be. Is there any other solution to keep air flow from below from coming into the house? Would adding a dehumidifier and changing the vents to not allow air up from below be sufficient? Does it need to be open like it is now unless we do the encapsulation? Also want to know if encapsulation would necessitate changes to the way our HVAC is currently set up as this would have a large additional cost implication- Seems like there may be some venting or emergency run off valves that are directed to the crawl space from the HVAC and water heater.
