I get the logic behind opening up a big section to check for hidden water, but sometimes that can cause more harm than good, especially in plaster walls. Moisture meters are great, but I’ve seen readings get thrown off by metal lath or old nails. Sometimes, targeted inspection and patience—like letting things dry out fully before tearing into everything—can save you a headache and some cash. Just my two cents from a few jobs where we went overboard and ended up with unnecessary demo.
I hear you on the over-demo. I was on a job last winter where the homeowner freaked out and wanted half their living room wall gone after a pipe burst. We ended up opening way more than we needed, only to find out most of the water had actually run down into the crawlspace. The moisture meter kept beeping like crazy near some old wiring, so that didn’t help either.
Honestly, sometimes it’s better to just poke a few holes, maybe pull a baseboard or two, and give it a few days with fans going full blast. Plaster’s a pain—once you start tearing into it, you’re basically signing up for a mess and a half. I get wanting to be thorough, but there’s something to be said for not making more work (and cost) than you have to. It’s always a bit of a gamble though… nobody wants hidden mold surprises down the line.
I get where you’re coming from, but honestly, I’d rather deal with a mess up front than risk hidden mold. We had a small leak in our laundry room last year—just a slow drip behind the wall—and I thought I could get away with fans and a dehumidifier. Looked fine on the surface, but a few months later, the musty smell started creeping in. Ended up having to rip out way more drywall than if I’d just gone for it right away.
I know demo is expensive and nobody wants to live in a construction zone, but mold remediation is a whole different level of headache (and cost). Sometimes it feels like you’re overdoing it, but I’d rather be safe than sorry. Maybe I’m just paranoid after my experience, but I’d pay more for peace of mind than risk missing something nasty behind the walls.
I get where you’re coming from—mold is such a pain. I’ve walked into jobs before where folks tried to “dry it out” with fans, only to discover way more going on behind the scenes. It’s wild how little water it takes for drywall and insulation to become a breeding ground, especially if the leak’s been slow and sneaky. Your point about upfront demo costing less than remediation down the line is spot on. Once those spores get a foothold, it’s like they’re in there for the long haul.
On the flip side, I’ve seen people tear out half their house because of a single wet patch, and sometimes it turns out to be overkill. There’s a balance, but I tend to err on the side of caution too, especially if there’s that lingering musty smell or visible staining.
For anyone reading this and wondering what to do after a burst pipe, here’s what I usually suggest:
1. Find the source and stop the leak—shut off the water ASAP.
2. Get rid of any standing water as quickly as possible.
3. Pull off baseboards and drill some holes at the base of the drywall to get airflow in there. Sometimes you can save a wall if you act fast.
4. If the water’s been sitting for more than 24-48 hours, or you start seeing swelling/warping, I recommend cutting out at least a foot above the water line. Mold loves those dark, damp spaces.
5. Always check insulation. If it’s wet, it’s gotta go.
6. Don’t forget to document everything for insurance—photos, receipts, all of it.
Curious—has anyone here tried using moisture meters to check behind the walls before deciding on demo? I’ve found them pretty helpful for figuring out just how far the damage goes, but I wonder if folks think they’re worth the investment or if it’s just better to play it safe and open things up anyway.
I actually bought a moisture meter after my basement flooded last year. I was skeptical at first, but it turned out to be pretty useful—found a couple spots that looked fine but were still wet inside. That being said, I still ended up cutting out more drywall than I wanted just to be sure. Guess I’d rather patch a wall than deal with mold sneaking up later. Those meters are handy, but my nerves usually win out over the gadgets.
