If you live in the Avenues, or anywhere in Chico’s older streets, there’s a decent chance the reason your drains are slow is growing right outside your window.
Chico has some of the most beautiful street trees in Northern California — huge, old, generous shade in a town that badly needs it. Those trees are also the single most common cause of sewer trouble we see here, and it isn’t close.
Gallagher’s has cleared Chico drains since 1989. We’re the Stand Up Guys, and we’ll tell you exactly what’s happening under your house before you spend a dollar.
Why Chico’s drains fail: the roots
Here’s the mechanism, because once you understand it the rest makes sense.
Homes built before roughly 1975 — which is most of the Avenues, most of downtown, and a lot of the older streets around them — typically have a clay sewer lateral. Clay pipe was the standard for decades. It’s durable, but it’s brittle, and it’s laid in short sections with joints between them.
Over fifty or seventy years, the ground shifts. A joint loosens. A hairline crack opens.
Now: a tree root’s entire job is to find water. In a Chico summer the ground is bone dry for months — and the wettest, warmest, most nutrient-rich thing anywhere near that root system is the inside of your sewer line. The root finds the crack, sends in a fine tendril, and then thickens — prying the crack wider as it grows, year after year.
Eventually you have a root mass inside the pipe, catching every bit of grease and paper that goes past it.
The signs, in the order people usually notice them
- The shower drains a little slow. You don’t think much of it.
- The toilet gurgles when the washing machine empties, or the tub burps when you flush.
- More than one fixture is slow at the same time.
- It gets noticeably worse after rain.
- It backs up. Usually on a weekend, usually into the lowest drain in the house.
The rain part is the tell. Roots go where the water is, and the first real storms of the season are when a lot of Chico homeowners discover the problem they’ve quietly had for years. If your drains are gurgling in September, do not wait for December to find out why.
What we do about it
A camera first. We put a sewer camera down the line and you watch the screen with us. Ten minutes and the guessing stops — you’ll see the roots, or the crack, or the belly in the pipe, or the fact that it’s actually just grease and this is going to be a cheap day.
Then the right tool, honestly chosen:
- Rooter / mechanical cutting — cuts the root mass out of the line and restores flow.
- Hydro jetting — high-pressure water scours the pipe back to bare wall, clearing the root debris and the grease and scale it was catching. On a root-fouled line this is usually the honest answer.
- Sewer line repair or replacement — when the clay is broken badly enough that cleaning it is just renting time.
Here’s the part we want to be straight about: cutting roots out does not remove the crack they came through. They will come back. How fast depends on the tree and the damage. If your line is in decent shape, periodic cleaning is a perfectly reasonable way to live — it’s cheaper than a replacement and plenty of Chico homes run that way for years. If it’s badly broken, we’ll show you on the camera and tell you honestly that cleaning it is a temporary fix.
We’d rather you hear that from us than find out the hard way in January.
It isn’t always the roots
Not every Chico drain problem is a tree. The other regulars:
Grease in the kitchen line. Goes down warm, hardens cold, coats the pipe. The single worst week of the year for this is Thanksgiving — every plumber in Butte County knows it.
“Flushable” wipes. They go down; they do not break apart. Two hundred feet later they snag on a root and catch everything behind them. We have pulled these out of sewer lines all over this town.
Student housing turnover. Chico is a college town, and the rentals near campus take a particular kind of abuse. Landlords: a camera inspection between tenants is a lot cheaper than an emergency call during finals week.
Old cast iron. Some of the oldest downtown properties have cast iron drain lines inside the walls. They scale up internally and slowly choke themselves. Jetting clears them; the camera tells us how much life is left.
Before you call anyone: two free things
If a bathroom smells like sewer, run the tap for thirty seconds. That U-bend under the sink holds water, and that water is the only thing between you and the sewer. In a guest bath nobody uses, it evaporates. Refilling it costs nothing and it fixes the problem more often than you’d think. (More on that in our guide to why your bathroom smells like sewer.)
And please don’t pour chemical drain cleaner down it. It’s caustic, it’s poor at clearing roots and grease, and it corrodes the pipe while it fails. We replace pipe that was killed by the product somebody bought to save it.
What it costs
Clearing a single slow sink and jetting a root-packed main line are not the same job and shouldn’t cost the same. What we promise:
- The price before we start. In writing.
- Bigger job than expected? We stop and re-quote. No surprises at the end.
- The camera means we quote what’s actually wrong — not what we guessed.
- If a free fix will do it, we’ll say so.
Buying an older Chico home?
Scope the sewer line before you close. A camera inspection is the cheapest insurance in real estate, and in a town full of century-old houses under seventy-foot trees, it is not a theoretical risk. We do a lot of these, and the ones that come back clean are worth the money too — you get to stop wondering.
Chico drain cleaning FAQs
Why do my drains back up when it rains?
Roots chase water. After a storm the soil is saturated, root activity increases, and a line that was marginally flowing tips over into blocked. It’s the most common seasonal call we run in Chico.
How do I know if I have roots in my sewer line?
Gurgling drains, multiple slow fixtures, and backups that worsen after rain — especially in a pre-1975 home with big trees. A camera confirms it in ten minutes.
Will cutting the roots fix it permanently?
No, and we won’t tell you otherwise. Cutting restores flow; it doesn’t repair the crack the roots came through. Depending on the damage, that’s either a reasonable maintenance rhythm or a sign the line needs replacing. The camera tells us which.
Do I have to cut down my tree?
Almost never. Repairing or relining the pipe solves the problem without touching the tree. Chico’s trees are part of why people live here — we’re not going to tell you to kill one.
How often should I have my sewer line cleaned?
If you have big mature trees and a clay lateral, having it scoped every couple of years is cheap insurance. Most homes don’t need it on a strict schedule.
Do you offer emergency drain service in Chico?
Yes. A backed-up main line isn’t a “wait till Tuesday” problem and we don’t treat it like one.
