Plastic liners definitely get a lot of mixed feedback, but I think they’re worth a closer look in some cases. Here’s where I see things a bit differently:
- If the pipe’s got a bunch of small cracks or root intrusion but isn’t totally collapsed, a good-quality liner can actually last decades. The key is making sure the install crew really knows what they’re doing—bad prep or shortcuts lead to those weird smells and shifting you mentioned.
- Foaming root killer’s more of a band-aid, yeah. It slows things down but doesn’t fix the underlying issue if the pipe’s already compromised.
- Full replacement is a pain, no doubt, but sometimes it’s the only way to actually solve the problem long-term. I’ve seen folks spend thousands over years on patch jobs and chemicals, only to finally cave and replace the line anyway.
Not saying everyone needs to rip everything out, but sometimes biting the bullet upfront saves a lot of headaches down the road. Just depends on how bad the damage is and how long you want to keep fighting roots every year...
Had to deal with this exact headache at one of my older duplexes a couple years back. Here’s what I ran into:
- Tried the foaming root killer route for a while. It bought me maybe six months at a time, but the roots just kept coming back thicker. Not a real solution, just slowed the inevitable.
- Got quotes for both lining and full replacement. The liner was tempting—cheaper upfront, less mess—but I was worried about the prep work. If the crew misses even a little debris or doesn’t smooth out the cracks, you’re looking at weird smells and possible backups down the line.
- Ended up biting the bullet and doing a full replacement. Cost more, but honestly, haven’t had a single issue since. No more annual root drama, no more tenants calling about slow drains.
If the pipe’s not totally shot, a liner can work, but you really need a crew that knows their stuff. In my case, the peace of mind from a full replacement was worth it. Sometimes you just have to rip off the band-aid...
Had a similar saga with a 60s ranch I look after. Tried the foaming stuff too—just felt like putting a band-aid on a broken leg.
—yep, every time, like clockwork. Ended up going trenchless for the replacement, which was pricier but way less yard destruction. Haven’t looked back since. Sometimes you just gotta do it right and be done with it.“the roots just kept coming back thicker”
Honestly, I hear you on the foaming stuff. Tried it myself—felt like flushing money down the drain, literally.
That’s exactly it. You patch it up, cross your fingers, and then a few months later you’re back to square one, or worse.“just felt like putting a band-aid on a broken leg”
Trenchless is a tough pill to swallow cost-wise, but sometimes you just have to bite the bullet. I dragged my feet for ages because of the price tag, but after the third time digging up the same patch of lawn, I realized I was just throwing good money after bad. The yard stayed intact, and I haven’t had to think about roots since.
It stings at first, but in the long run, it’s less stress and less cash wasted on temporary fixes. Sometimes “doing it right” really does pay off, even if it hurts the wallet up front.

I know what you mean about the cost of trenchless—my jaw dropped when I first got the estimate. But after a couple rounds with the foaming stuff (and a bottle of root killer that did nothing), I started to feel like I was just “throwing good money after bad,” like you said. Here’s how it went for me:
Step 1: Tried the cheap fixes. Didn’t last.
Step 2: Watched my basement floor start to get damp again.
Step 3: Realized I was worrying every time it rained, which got old fast.
Step 4: Bit the bullet and went trenchless.
It hurt up front, but honestly, not having to worry about roots or surprise backups is worth it. I do think if your pipes are in okay shape and you’re just dealing with minor roots, maybe the foaming stuff buys you some time. But for me, it was just delaying the inevitable.
If you’re on the fence, I’d say weigh the stress factor too—not just the dollars. Peace of mind’s hard to put a price on, but man, it’s nice not thinking about pipes every week.
