Out of curiosity, have you ever had to deal with hidden plumbing issues during a reno? In my experience, those seem to sneak up more often than electrical surprises.
Totally agree—plumbing’s the real wild card. Quick rundown from my last flip:
- Opened a wall expecting minor fixes. Found a “creative” PVC patch job instead.
- Drain pipes looked fine outside, but inside? Corroded and leaking into insulation.
- Cost me an extra week and a few grand.
Lesson learned: always budget extra for plumbing, even if things “look” decent. Surprises love to hide behind tile.

That’s the truth. I always do a “peek test”—pull a few outlet covers or baseboards to check for water stains or weird smells before committing. Not foolproof, but it’s saved me from at least one hidden leak. Still, sometimes you just can’t see what’s lurking until demo day...

Surprises love to hide behind tile.
Ain’t that the truth. Last kitchen I gutted, everything looked peachy until I pulled the cabinets and found a “bonus”—a pipe patched with duct tape and hope. I mean, who does that? My trick is to budget for at least one “oh no” moment per room, especially anywhere near water. Peek tests help (I do the sniff test too—nothing like eau de mildew to get the heart racing), but you’re right, some stuff just waits until you’ve got a crowbar in hand.
If you ever feel lucky because the inspection report looks clean, just remember: inspectors don’t have x-ray vision, and old houses are basically escape rooms for your wallet. My advice? Always have a little extra stashed for the stuff you never planned on... unless you enjoy living with “character” leaks.

That’s such a good way to put it. I’ve seen so many “character” leaks turn into full-blown design challenges. Have you ever tried those little moisture meters before demo? They’re not perfect, but sometimes they’ll catch damp spots behind walls before you start swinging hammers. I always tell folks—if you’re opening up a kitchen or bath, just assume there’s a surprise lurking somewhere. Makes the good surprises (like original hardwood under vinyl) feel like winning the lottery.

That’s honestly the perfect analogy—old houses are like a wallet-eating escape room. I’ve always tried to budget for “unknowns,” but it’s wild how fast those add up. Moisture meters are a decent tool, but I’ve found they can be a bit hit or miss, especially if you’re dealing with old plaster or weird insulation. Sometimes I wonder if they just give me a false sense of security. I still end up poking around with a screwdriver in suspicious spots, just in case.
One thing I wish I’d known before starting our bathroom reno: even if everything looks fine on the surface, you can’t really predict what’s behind the tile until you start demo. We thought we were being smart by checking for leaks and using a moisture meter, but once the wall was open, there was this ancient galvanized pipe that had basically corroded shut. No way to spot that without opening things up. That added a few thousand to the bill, and it wasn’t even on our radar.
I’ve started assuming that every project will have at least one “surprise” line item. Sometimes it’s minor, like finding knob-and-tube wiring where you expected updated electrical. Other times, it’s a full-on structural issue. I do agree, though, that finding something good—like original hardwood or cool old trim—makes the headaches feel a little more worth it. Still, I’d rather not gamble with my savings every time I want to update a room.
If there’s one thing I’d tell anyone starting a reno, it’s to pad your budget more than you think you need. And maybe keep a sense of humor about it, because at some point, you just have to laugh when you find yet another “quirk” hiding in the walls.
