EWC88 24 Posted October 1, 2017 Hey guys, have yet another house hold question. Other day I decided to clean out the nasty crawl space. While in there I noticed I have two vent plates. One was close the other was open. Now also while noticing this I saw that the one is loose and needs to be held in better to prevent critters. When googling what’s the best was to hold vent up I came across links to people having mix reviews on vents. Some said to disregard and have permanently shut while others said they are smart. So what are your thoughts? Quote Share this post Link to post Share on other sites
T Bill 649 Posted October 1, 2017 Ventilation is a good thing, allows moisture to dissipate and not condense on things, that causes mold, rust and rot esp, when you are located in a Mixed-Humid climate. 2 Quote Share this post Link to post Share on other sites

Zeke 5,504 Posted October 1, 2017 My foamers will tell you, foam slab, and walls.. right over the vents.. rat slabs are ginormous sponges.. throw a hygrometer down in the crawl in the summer... vents open. Let me know the humidity Quote Share this post Link to post Share on other sites
EWC88 24 Posted October 1, 2017 My concern with the foam, if you are referring to “Great Stuff” in aersonal, mice can just chew their way through. Quote Share this post Link to post Share on other sites

Barms 98 Posted October 2, 2017 This debate has been going on for years. First thing we need to know is the bottom of crawl space dirt or concrete? 1 Quote Share this post Link to post Share on other sites
Handyman 5,682 Posted October 2, 2017 Generally you want it to breathe. If you have a concrete floor, tape down a piece of plastic sheeting and see if you get condensation under it. Quote Share this post Link to post Share on other sites
Zeke 5,504 Posted October 2, 2017 Better, go to bestbuy and buy a cheap weather center with a remote sensor.. jus make sure it does humidity. $20 and watch. do you have signs of mold? Quote Share this post Link to post Share on other sites
EWC88 24 Posted October 3, 2017 No signs of mold. Crawl space floor is concrete, walls are cinder blocks. Quote Share this post Link to post Share on other sites

EWC88 24 Posted October 3, 2017 I’ll havw to find those vents. zeke I know! I am, my next issue to fix is calling around to see who will take up my patio and level and reinstall pavers. There’s low spots which is causing efflorescence in that area in the basement...lovely Quote Share this post Link to post Share on other sites
