So this is what happened...
There are ongoing heavy moisture problems in the crawl. The new beam and wolm post support set-up was installed because the old supports rotted/rusted out and were no longer supporting squat. Also the crawl freezes.
The new set-up will rot out in a few years time, especially the beam. The wolm support is BS and should be replaced with solid posts.
How do I know this besides experience?
- The condition of the plastic on the floor
- The pvc repair sleeve on the copper supply line
- The discoloration everywhere
Recommend:
- provide ventilation and insulation for crawl
- insulate copper piping
- install proper support posts for beam
- determine if beam is adequate for the load
- remove the funky plastic, clean the ground, install gravel proper vapor barrier and/or cement
- assess the foundation cracks; are they hairline from all the moisture or are they deep?
- is that beam single or double? I don't see any bolts holding two together
- properly attach the end of the beam to the foundation wall, not just that BS piece of wolm support; I don't see any bolts in that either
- remove the screw jack and install permanent support
Did you look at the downspouts outside? Are they draining next to the wall or out 6'. Figure out the moisture issue and you will be the next coming of you know who to your client.
Just a few thoughts. Good luck
