Fast, Reliable Sewage Cleanup Across Clovis
A sewage backup in Clovis is a serious health and structural emergency, and it won’t wait for regular business hours. A typical Sewage Cleanup in Clovis runs $1,800-$4,500 for a contained bathroom overflow and $6,000-$15,000 when black water reaches multiple rooms or a crawl space. Our crews reach most Clovis neighborhoods within 45-60 minutes, any hour, any day. Call (888) 737-2439 and a live dispatcher answers. That’s not a recording. That’s a person who knows the difference between a toilet overflow in Old Town and a slab-line failure in east Clovis and can have a certified crew rolling before you hang up.
Why Floodline Restoration Co. of California Is Clovis’s Preferred Sewage Cleanup Company
We’ve worked in Clovis long enough to know its rhythm. The older neighborhoods off Clovis Avenue with their original cast-iron drain lines. The 1990s tract homes in 93612 where builder-grade cleanouts buried under 20 years of landscaping give out on a Tuesday morning. The newer subdivisions in 93619 where expansive clay moves slabs and pipe joints in ways the original plumber never planned for. Homeowners in Clovis call us because our crews know what they’re looking at when they walk through the door, and because we answer the phone at 2 a.m. with a live voice, not a voicemail tree.
Every job gets a background-checked, uniformed technician trained to IICRC, RIA, and IFA standards. Every job is backed by our 90-Day Done Right Promise in writing. That means if the work isn’t right, we make it right. No arguing. No paperwork battles. Just done.
Our Sewage Cleanup Services in Clovis
Here’s what we handle most often across Clovis, from first extraction to finished sanitization.
Crawl Space Sewage Removal
Clovis homes built before 1975, especially in Old Town and the older pockets off Sierra Vista, often sit over crawl spaces with original cast-iron waste lines. Those lines crack. When they do, raw sewage pools under the house, and the smell comes up through the floorboards. We extract the black water, remove contaminated insulation and debris, treat the soil, and run professional-grade drying equipment until the moisture log reads dry as part of our Reconstruction & Cleanup in Clovis. This is not a job for a shop vac and hope. This is containment, extraction, and full sanitization.
Black Water Extraction
Category 3 water, what restoration pros call black water, carries bacteria, viruses, and parasites. It’s what comes out when a main line backs up into a Clovis home, when a toilet overflows past the bathroom, or when stormwater pushes sewage through a floor drain. We use truck-mounted extraction to pull the water out fast, then set up Dri-Eaz air scrubbers and Phoenix LGR dehumidifiers for Water Damage Restoration - Clovis. Every affected surface gets disinfected with EPA-registered antimicrobials. No shortcuts.
Sanitization & Disinfection
After the water is out and the drying equipment is running, the surface work begins. Hard surfaces get scrubbed and disinfected. Porous materials that can’t be reliably cleaned, like saturated drywall, carpet pad, or insulation, get cut out and removed. In Clovis’s dry climate, homeowners sometimes assume they can let things air out. That’s a mistake. Drying isn’t sanitizing. Our crews treat both, and we document every step for your insurance carrier.
Toilet Overflow Cleanup
A toilet overflow that’s caught early and contained to the bathroom is less costly, typically $1,800-$2,500 in Clovis. The real risk is what you don’t see: water running along the baseboard, under the vanity, into the wall cavity. Clovis’s stucco-over-frame construction hides that water well. We use moisture meters and thermal imaging to trace exactly how far the water traveled, then dry and sanitize every affected surface. If it stayed in the bathroom, we’ll tell you that. If it reached the hallway, we’ll show you the readings. You deserve straight answers, and you’ll get them.
Septic Failure Cleanup
Parts of Clovis east of Locan Avenue and along the newer 93619 subdivisions still rely on septic systems, though many have been converted as the city grew. When a septic line fails, sewage can surface in the yard and backflow into the house through drains and toilets. We coordinate with your septic contractor, handle the indoor cleanup and sanitization, and keep your insurance claim moving with photo documentation and moisture logs from day one. One crew. One point of contact. No mid-job handoff.

Common Sewage Cleanup Problems We See in Clovis Homes
These are the failure patterns we see repeatedly across Clovis. If any of them sound like your house, call before the damage spreads.
- Expansive clay slab movement in 93619: The valley clay under east Clovis shrinks and cracks during the long 100°F+ summers. When fall and winter rains return, water moves along those cracks and toward slab perimeters. Sewer and drain lines under the slab shift with the soil, and joints separate. The first atmospheric river of the season always brings a wave of sewage backup and garage flooding calls from east Clovis.
- Aging cast-iron drain lines in Old Town: The pre-1960 homes along Clovis Avenue and the surrounding streets still have original cast-iron waste lines in places. After 60 to 70 years in contact with valley soil, those lines corrode, crack, and collapse. Sewage doesn’t just back up. It leaks into crawl spaces and behind plaster walls. Old Town homes need crews who understand lead-paint-safe protocols and plaster-and-lath drying, because these homes dry differently than a modern stucco tract home.
- Builder-grade cleanouts and flat-lot drainage: Many 1990s-2010s Clovis subdivisions were built at speed with a single cleanout access and minimal lot slope. When the cleanout is buried under two decades of landscaping or a deck, a main-line block means sewage backs up at the lowest drain in the house before anyone catches it. Add atmospheric river rainfall, and the problem compounds fast.
- Tule fog and slow drying: From November through February, the San Joaquin Valley’s tule fog sits on Clovis for days or weeks. Relative humidity sits near 100%. A sewage spill that isn’t fully extracted and dried within 48 hours in those conditions will feed mold inside wall cavities. This is why we don’t delay and why we track daily moisture readings until the dry standard is met, not just until the surface looks fine.
How Clovis’s Expansive Clay and Tule Fog Shape Sewage Cleanup
Here’s what a generic restoration page won’t tell you. The sewage backup in your Clovis home is almost never just a plumbing failure. It’s a soil, climate, and construction problem stacked on top of each other.
East Clovis, and especially the 93619 ZIP, sits on former agricultural fields built over expansive valley clay. That clay bakes and cracks through Clovis’s dry 100°F+ summers. The ground literally opens up. When the first atmospheric river of the season rolls in, the upper soil can’t absorb the water fast enough, so it runs along those desiccated cracks and toward the lowest point: your slab perimeter. Sewer laterals and under-slab drain lines that shifted during the summer now separate under the added soil movement. The result is a predictable seasonal surge of sewage backup calls across east Clovis every November and December. Our dispatchers and crew leads plan for it because they’ve seen it year after year.
Then come the fog months. Days of near-saturation humidity. A sewage spill that would dry quickly in, say, Phoenix in July will sit wet inside a Clovis stucco wall cavity for weeks. That’s the window where Mold Remediation in Clovis becomes necessary. Our drying equipment, including Dri-Eaz HEPA 500 air scrubbers and Phoenix 200 MAX LGR dehumidifiers, is sized for exactly these conditions. Daily moisture readings tell us when the structure actually reaches the dry standard. Not when it looks dry. When it measures dry.
We saw this combination in a 2004 stucco tract home in the Buchanan Estates neighborhood of 93619. The original slab perimeter drain had settled as the expansive clay moved, and a toilet overflow sent black water under the slab edge and into the wall cavity below a poorly flashed window header. We contained the black water, set up air scrubbing and LGR drying, removed the saturated drywall, and mapped moisture throughout the affected wall cavities before sanitizing every surface. The homeowner had no idea the window header was part of the problem until our moisture mapping showed it. That’s what local experience does. It finds the second problem before it becomes a second claim.

FAQs - Sewage Cleanup in Clovis
Expansive valley clay under east Clovis shrinks and cracks during the dry season, then swells and shifts when atmospheric river storms arrive. That soil movement stresses under-slab sewer lines and perimeter drains, causing the joints to separate and back up. For cleanup, it means we check the entire slab perimeter and affected wall cavities, not just the visible spill area, because hidden water travels along those same soil cracks and slab edges. Call (888) 737-2439 for an assessment.
Tule fog keeps relative humidity near saturation for days or weeks from November through February, so spilled sewage and the moisture it leaves behind cannot air-dry on its own. In those conditions, mold can colonize inside stucco-wrapped wall cavities within 48 hours. Our crews run professional-grade dehumidifiers and air scrubbers continuously and take daily moisture readings until the structure measures dry, regardless of how the surface looks. Call (888) 737-2439 if you’ve had a spill and the fog is sitting on the Valley.
Older plaster-and-lath homes in Old Town dry differently than modern drywall construction, and our protocols are built around that. We use controlled, slower drying to protect the original plaster while still getting moisture out of wall cavities. If lead paint is present, we follow lead-safe containment and removal practices. The process is more delicate but the standard is the same: extract, dry, sanitize, document. We’ll walk you through each step before work begins.
Yes. Clovis averages only about 11 inches of rain a year, but atmospheric river storms can drop several inches in 48 hours. That overwhelms flat-lot drainage and builder-grade gutters, sending stormwater into slab edges, garages, and sometimes into sewer lines through floor drains. Homes with no prior plumbing issues can back up during these events because the sudden soil saturation shifts pipes and driveways. Catch it fast and the damage stays small. Call (888) 737-2439 day or night.
The first significant storm after Clovis’s long dry season hits desiccated, cracked expansive clay that can’t absorb water quickly. The water moves along soil cracks and toward slab perimeters, shifting under-slab lines and overwhelming drains all at once. It’s a predictable seasonal pattern in the 93619 ZIP, and it’s why our crews stage equipment and dispatch coverage before those first storms arrive. If it’s happening at your house, call (888) 737-2439 and we’ll be there when we say.
