Honestly, I’d be careful with those bolt-on flange repair kits. They can work in a pinch, but if the old cast iron is crumbling or uneven, you’re just stacking problems. I’ve seen folks use them and end up with leaks down the road—especially if the floor isn’t level or there’s movement. If you’re smelling rotten eggs, that could mean sewer gas is sneaking past a bad seal. Sometimes it’s worth biting the bullet and replacing the whole flange, even if it means breaking out some concrete. Not fun, but safer in the long run.

Couldn’t agree more about the risk with those bolt-on kits. I’ve tried them in a couple of my older rentals—one time it held up, but another time I was back two months later dealing with a nasty leak and a tenant who was (understandably) not thrilled. If the cast iron’s already crumbling, you’re just delaying the inevitable.
That said, I get why folks try to avoid busting up concrete. It’s messy, expensive, and if you’re not careful, you can end up with a bigger headache. But honestly, nothing beats doing it right the first time. Sewer gas isn’t just gross—it’s a health risk, and it’ll drive tenants away faster than anything. If you’re getting that rotten egg smell, I’d say don’t mess around with quick fixes. Just replace the flange and be done with it. It’s a pain now, but you’ll thank yourself later.
- Totally get the urge to save money and avoid tearing up concrete, but those quick fixes rarely last.
- I tried a “no-dig” repair once—saved a few bucks upfront, but ended up paying double when it failed.
- If you’re already smelling sewer gas, it’s not worth risking your health or property value.
- Sometimes you just gotta bite the bullet and do it right, even if your wallet cries a little.
I get why people want to avoid the mess and cost, but those temporary fixes just don’t hold up. I’ve seen a couple of “miracle” sealants that claim to stop sewer gas, but they usually just mask the problem for a bit. Has anyone actually had success with those, or do they all end up failing eventually?
Honestly, I’ve tried a couple of those “miracle” sealants when we first started getting that sulfur smell in our laundry room. They worked for a week or two, but then the stink crept back in. I get wanting to avoid the hassle and cost of a real fix, but in my experience, those quick fixes just don’t last. Plus, I always worry about what’s actually getting masked—sewer gas isn’t just gross, it can be dangerous if there’s a bigger leak somewhere.
I ended up just biting the bullet and having a plumber check the traps and venting. Cost more upfront, but at least I’m not stressing about what’s floating around in the air down there. Sometimes it feels like you’re saving money with the DIY route, but it adds up if you have to keep reapplying stuff or if you miss something serious. Just my two cents...
