Sewage backing up right now

Call Now — (833) 338-2528Same drain clogging repeatedly
In Thornton's older tracts this almost always points to Denver Water mineral scale or root intrusion through cracked cast iron joints. Another snake only punches a temporary hole — you need a camera and a deep clean.
Buying a home in Thornton
Scope the sewer before you close, especially on anything built before 1990 in the original Thornton tracts near 104th Avenue or around Eastlake.
One slow sink, tub, or shower
A same-day snake visit usually clears it in under an hour. We book same-day across all of Thornton's 80229, 80233, 80241, and 80602 ZIP codes.
24 Hour Emergency Drain Cleaning in Thornton
A sewer backup doesn't wait for business hours. Sewage comes up through the basement tub at 11 pm. A floor drain backs up during a Sunday morning load of laundry. That's when you find out whether your drain company is actually reachable or just says it is.
When you call (833) 338-2528, a real member of our team answers — day or night, weekday or holiday. Our 24 hour emergency drain service dispatches with fully stocked trucks so we never leave mid-job to get parts.
Call us immediately if you see:
- Sewage backing up into a tub, shower, or floor drain
- Waste rising from a basement floor drain
- A toilet that won't flush while other drains back up
- Sewer smell inside the house or rising from the yard
We work every night, every weekend, and every holiday including Christmas, Thanksgiving, and the Fourth of July.
Thornton Drain Cleaning and Sewer Services
Every job starts with finding what is actually wrong. Flat price before we touch anything. Smallest fix that solves it permanently.
Drain Snaking and Rooter Service
A motor-driven cable runs 75 to 100 feet into the line, cuts through hair, grease, and soft buildup, and pulls the clog out. Most visits are done in under an hour. When rooter service isn't the answer is when the same drain clogs back within a few weeks — we show you on camera before recommending anything more.
$100 – $300Hydro Jetting in Thornton
High pressure water scours the full pipe wall — flushing out grease in kitchen lines, the mineral scale that Denver Water's hardness leaves behind, and root debris packed into older cast iron. We camera the pipe before jetting every time — deteriorated cast iron needs careful handling before any pressure is applied.
$350 – $1,400Sewer Camera Inspection
A camera stops the guessing. We run a waterproof camera down the line while you watch the monitor — you see the roots, crack, grease coating, or low spot for yourself. A surface locator pinpoints the exact depth and location of any problem. You get the recorded video and a plain written summary to keep.
$125 – $500Main Sewer Line Cleaning
When every drain in the house backs up or slows at once, the blockage is in the main sewer line. Left alone it ends in a basement full of sewage. We camera first, then clear with a heavy cable for roots and solids or jetting for grease and scale. Camera goes back in to confirm end to end after clearing.
$150 – $500Sewer Backup Repair and Trenchless Replacement
When the camera finds cracked, collapsed, or root-wrecked pipe, cleaning won't hold. Pipe bursting threads a new pipe through the old one. Pipe lining hardens a resin sleeve into a new wall inside the existing pipe. Both work from two small access points — lawn and landscaping stay in place. When open digging is genuinely the right call, we say so.
$1,500 – $15,000Kitchen Drain Cleaning
Grease, oil, and food cool and solidify where the kitchen drain narrows past the trap. We clear it at the source with a cable sized for kitchen pipe. When grease has built up along the walls over years, we jet the line. If your disposal hums but the water backs up, the problem is almost always the drain line, not the disposal itself.
from $100Bathroom and Shower Drain Cleaning
Hair and soap scum bind together in the trap and trap arm. We pull the cover, run a cable through to where the clog sits, and pull it out completely. If the shower, tub, and sink all drain slowly at the same time, we check the main line rather than clearing drains one at a time.
from $100Clogged Toilet and Floor Drain Cleaning
A toilet that gurgles, overflows, or refuses to flush fully needs a closet auger — not a plunger. We clear the bowl without scratching it and pull the toilet if the clog sits deeper in the line. Floor drains that back up during laundry are a common main line signal. We treat these as same-day calls any day of the year.

You call, a real person answers.
Any hour, any day. Same day appointments are standard across all Thornton ZIP codes, and we dispatch immediately for emergencies.
Camera first, always.

Flat price in writing.
You see the number before any work begins. If the camera finds something unexpected, we stop and talk before we proceed.
Right tool for the actual problem.
Rooter for a simple clog. Jetting for grease and scale. Trenchless repair for a broken pipe. Open digging only when nothing else will hold.
Camera again after the job.
We confirm the line is clear from end to end before we leave. You see the clean pipe on the monitor.
Why Thornton Chooses Us Over Other Drain Cleaning Companies
Why Drains Clog Faster in Thornton Than Most Cities
Thornton has two drain problems that compound each other — and they affect different parts of the city in different ways.
Hard Water from Denver Water's South Platte System
Denver Water delivers water to Thornton at roughly 8 to 9 grains per gallon of hardness — above the threshold where mineral scale starts depositing inside pipes year after year. The pipe gets narrower on the inside every year. A snake punches a temporary hole through the scale but leaves the buildup coating the walls, so the same clog returns faster each time. Hydro jetting scours the full pipe wall and resets the original interior diameter. That's why jetting holds much longer in Thornton than a snake alone.
1960s–1980s Cast Iron and Expansive Front Range Clay
Thornton developed rapidly as a postwar suburb starting in the late 1950s and through the 1970s. Those homes — particularly the tracts near original Thornton around 104th, Parkview, Forest Park, and Eastlake — went in with cast iron sewer laterals that are now 50 to 65 years old. The expansive clay soil underneath shifts during Front Range freeze-thaw cycles, cracking the cast iron joints. Tree roots find those cracks. Corrosion narrows the pipe from the inside. The newer Todd Creek and Heritage Todd Creek developments run PVC and don't have these structural issues — their problems are grease and hair, not cracked pipe. Knowing which era of construction your home is tells us the entire diagnostic before we pull the camera.
Original Thornton vs. Eastlake vs. Todd Creek — Three Different Drain Problems
Original Thornton Tracts — 104th, Parkview, Forest Park
Homes built in the 1960s and early 1970s on the original Thornton plat. Cast iron sewer laterals now 50+ years old. Expansive clay shifting the joints. Cottonwoods and box elders planted along the original streets sending roots through every crack. This is where a camera check and trenchless repair saves the most money over repeat snaking calls.
Eastlake and Hunters Glen — 1980s and 1990s Builds
A mix of cast iron in the older sections and early ABS plastic in the newer. Mineral scale from Denver Water is the primary culprit — pipes that have never been jetted are significantly narrowed inside by now. Root intrusion is still a factor near Eastlake where mature trees line the streets. Hydro jetting every three to five years keeps these lines running clean.
Todd Creek, Trail Winds, and Heritage Todd Creek — 2000s+ PVC
Modern PVC and ABS pipe installed correctly doesn't crack or corrode. Drain problems here are grease from busy kitchen lines, hair in bathroom drains, and hard water scale beginning to accumulate in pipes that are now 15 to 20 years old. Snaking clears the clog; jetting keeps it clean for years. No structural concern yet — but hard water scale is already building on the interior walls.
We Know All Three
We run drain and sewer calls across Thornton every week. The camera tells us which situation we're in within minutes of entering the line — and we bring the right fix the first time.
Signs Your Thornton Drain or Sewer Line Needs Cleaning
Call before a slow drain becomes a flooded basement:
Multiple drains slow at once
Every drain in the house connects to one main sewer line. When several slow down together, that line is the problem — not the individual fixtures.
Toilet gurgles after flushing
Air bubbling back past a partial main line blockage — one of the earliest warnings before a full backup.
Sewer smell inside or in the yard
A cracked cast iron joint is venting gas into the house or into the soil — common in Thornton's older tracts.
A wet, green patch in the yard
A leaking sewer lateral is feeding that grass with nutrients and water from below. The pipe is already cracked and needs a camera look.
The same drain clogs every few weeks
The buildup — mineral scale, grease, roots — was never fully removed, just punched through. Skip the store-bought chemicals. They soften the top layer and eat at older pipe, leaving the real cause untouched.
Buying a Home in Thornton? Get a Sewer Camera Check First
A standard home inspection does not include the buried sewer lateral. For $125 to $300 we run a camera from the house to the city main and show you exactly what you're buying.
This matters particularly in Thornton's original tracts built in the 1960s and 1970s. Cast iron pipe that is 50 to 60 years old, cracked by expansive clay movement and root intrusion, does not show up in a visual walkthrough of the house. A camera check finds these problems before you close — when you still have options: a price adjustment, a repair credit, or the choice to walk away.
You get the full video recording and a plain-language written summary. No sales pressure. Just what the camera shows.
Commercial Drain Cleaning in Thornton
Restaurants and food service businesses along 104th Avenue and 120th Avenue push grease, food waste, and high daily volume through their drain lines from open to close. A clogged kitchen drain during service costs money every minute. We clear commercial drains, service grease traps, and build regular jetting schedules around your operating hours so a drain problem never shuts down your kitchen.
For office buildings, retail centers, and multi-tenant properties throughout Thornton and the 144th Avenue corridor, we handle one-time backups and ongoing maintenance plans. Fast response, camera documentation, and records for every address.
Drain and Sewer Service for Landlords and Property Managers in Thornton
Thornton's rental market includes a significant number of 1970s and 1980s tract homes that have seen decades of tenant turnover without ever having their sewer laterals professionally cleaned or inspected. We handle emergency calls and set jetting schedules between leases — with camera reports for every address so you have a written record of condition at each visit.
One call covers a single Thornton rental or your entire Adams County portfolio.
Residential Drain Cleaning Service in Thornton
For homeowners, we take the time to explain what the camera shows and what your options are — so you understand your own plumbing and can make an informed decision. No upselling. No unnecessary work. Our residential drain cleaning service covers everything from a slow shower drain in a new Todd Creek home to a full sewer line replacement under a 1960s original Thornton lot.

Who Owns the Line and Why It Matters
The city of Thornton owns the sewer main running under the street. You own the lateral — the pipe from your foundation to that main. Every residential sewer problem happens on your lateral, on your dime. Most homeowner insurance policies exclude sewer backup unless you add a rider. That rider typically runs $50 to $150 per year — far less than a basement cleanup after a main line failure in a 1970s Thornton home.
