Copper mesh is a game changer for critter control, no doubt. I tried the “eco” foam wraps one year—figured less plastic, right? But mice chewed right through and made a nest. Ended up with a bigger mess and wasted insulation. Lesson learned: sometimes the greener option isn’t always the most practical for pipes in crawlspaces. Now I use recycled-content fiberglass and proper heat cables, and just check everything before the first freeze.
Copper mesh definitely holds up better than most of the “green” wraps I’ve seen. I’ve had folks call me out after rodents got through those foam sleeves—they look fine at first, but it’s like a welcome mat for mice. Recycled fiberglass is a solid compromise, just gotta watch for any gaps or tears over time.
Out of curiosity, do you ever run into condensation issues with fiberglass in crawlspaces? Sometimes I see folks skip the vapor barrier and end up with damp insulation by spring. It’s a pain to replace, and can even lead to mold if you’re not careful. I always recommend double-checking the vapor barrier before winter hits, especially in older homes. How are you keeping your crawlspace dry these days?
Condensation in crawlspaces is the bane of my existence every spring. I swear, I’ve pulled out more soggy fiberglass than I care to admit—sometimes it feels like it’s growing its own ecosystem down there. You’re spot on about the vapor barrier; if it’s not sealed up tight, you might as well roll out a red carpet for mold.
I’ve started doubling up on the plastic sheeting—one layer under the insulation and another over any exposed dirt. It’s not pretty, but it keeps things dry enough that I don’t gag when I have to go under there. Also, I’ll prop open a vent or two on dry days just to let things air out. Some folks say vents are old school, but in my area, it helps.
Funny thing—my neighbor tried using those “breathable” wraps last year… ended up with condensation AND a family of mice. He’s back to copper mesh and heavy-duty plastic now. Sometimes old tricks really do work best.
I hear you on the crawlspace drama—mine’s like a swamp every April. I tried those fancy “moisture control” sprays once, but honestly, a big roll of 6-mil plastic and a staple gun did more for my wallet and my sanity. I’m with you on the vents too. Folks keep telling me to seal everything up tight, but if I don’t crack a vent on dry days, it just gets musty and weird. Sometimes the old-school fixes are the only ones that don’t break the bank... or invite critters.
I get where you’re coming from, but fully sealing up the crawlspace actually worked better for me in the long run. Used to do the vent thing like you, but I kept getting weird smells and a mildew problem that wouldn’t quit. Once I sealed it tight and ran a cheap dehumidifier, it finally stayed dry and critter-free. Not saying it’s perfect for everyone, but sometimes the “new school” fixes pay off too... just depends on the house, I guess.
