DIY vs. Professional Sewage Cleanup: How to Decide the Best Approach for Your Home

Heads up: Your Basement’s Flooded with Sewage! What Should You Do? 

Picture this: You wake up and there’s a terrible smell creeping through your house. You trace it to the basement and—surprise!—there’s raw sewage bubbling up from the drain. Total panic mode, right? Should you throw on some gloves and dive in, or just call a pro? It’s not always a clear call. 

So how do you figure out if you should handle the sewage cleanup yourself or bring in the experts? 

Here’s the deal: Not all sewage messes are the same. 

From a little toilet overflow to a complete sewer nightmare, this guide will help you sort through the risks, costs, and safety stuff to help you make the best choice. Let’s jump in (figuratively, of course)!

1. The Honest Truth About Sewage Cleanup: It’s Not Just Dirty Work

Dealing with sewage is about more than just the gross factor; it’s a serious health hazard. Here’s the lowdown: 

  • Bad Bugs: Raw sewage carries nasty bacteria (think E. coli and salmonella), along with viruses and parasites.
  • Toxic Mix: Household cleaners, medications, and industrial waste can all end up in the sewage, creating even more problems.
  • Structural Damage: If sewage lingers, it can damage floors, ruin drywall, and corrode pipes.

The #1 Rule: If the sewage has poop in it or comes from a sewer line, treat it like a serious biohazard.

2. DIY Sewage Cleanup: When It’s Possible (and Safe)

Scenario 1: Minor Cleanups

  • Example: A toilet overflow limited to a small bathroom floor.
  • Safety Level: You’re pretty safe as long as the water is “clean” (meaning no poop or chemicals hanging around).

What You’ll Need:

Steps to Take:

  1. Turn off electricity in the affected area.
  2. Grab a wet vacuum to suck up any standing water.
  3. Mix up a bleach solution (1 cup of bleach to 1 gallon of water) and disinfect those surfaces.
  4. Set up some fans and dehumidifiers to make sure everything dries out completely.

Scenario 2: Small-Scale Gray Water Spills

  • Example: A washing machine leak without sewage contamination.
  • Safety Level: Moderate risk. Wear full protective gear.

DIY Limitations:

  • Avoid DIY if water has seeped into carpets, drywall, or subflooring. Mold grows fast!

3. When to Call the Professionals: Non-Negotiable Situations

Red Flags That Demand Expert Help:

  1. Black Water Contamination: Sewage from toilets, sewer lines, or floodwater.
  2. Large-Scale Damage: Water affecting multiple rooms or rising above 2 inches.
  3. Hidden Contamination: Sewage under floors, behind walls, or in HVAC systems.

What Pros Bring to the Table:

  • Advanced Gear: Industrial pumps, air scrubbers, and antimicrobial treatments.
  • Safety Protocols: OSHA-certified handling of biohazards and chemical waste.
  • Insurance Help: Documentation for claims and damage assessments.

Pro Tip: Look for companies certified by the Institute of Inspection, Cleaning and Restoration (IICRC).

4. Cost Comparison: DIY Savings vs. Professional Value

Factor

DIY Cleanup

Professional Cleanup

Cost

100–100–500 (supplies, rental)

2,000–2,000–10,000+ (depending on severity)

Time

8–24 hours of labor

1–5 days (experts work faster)

Health Risk

High if mishandled

Minimized with proper PPE/tools

Long-Term Safety

Mold risk if incomplete

Guaranteed drying/disinfection

When DIY Backfires:

  • Incomplete cleanup → mold growth ($5,000+ remediation).
  • Improper disposal → fines for environmental violations.

5. How to Choose: 5 Questions to Ask Yourself

1. What’s the source of the sewage?

  • Toilet/sewer line? Call pros immediately.
  • Washing machine? DIY may work if contained.

2. How big is the affected area?

  • Larger than 10 sq. ft.? Pros can handle it faster.

3. Are vulnerable people in the home?

  • Kids, elderly, or immune compromised? Don’t risk DIY.

4. Is there structural damage?

  • Buckled floors or soggy drywall? Pros have drying tools.

5. Does insurance cover it?

  • Most policies cover sewer backups if you hire licensed pros.

6. The DIY Checklist: If You Decide to Go It Alone

  • Wear PPE: Gloves, goggles, mask, and waterproof boots.
  • Ventilate the area: Open windows, run fans.
  • Dispose of waste properly: Contact your city for biohazard disposal rules.
  • Test for moisture: Use a moisture meter to confirm dryness.
  • Monitor for mold: Check for smells/discoloration weekly.

Critical Mistake to Avoid: Never mix bleach with ammonia or vinegar—it creates toxic fumes!

7. Finding a Reliable Sewage Cleanup Company

  • Check Credentials: IICRC certification + licensed, insured, and bonded.
  • Read Reviews: Look for 4.5+ stars on Google, Yelp, or Angi.
  • Ask About Gear: Do they use HEPA air scrubbers? Thermal cameras for hidden moisture?
  • Get a Detailed Contract: Should outline costs, timeline, and guarantees.

Red Flags in Contractors:

  • Demands full payment upfront.
  • No references or physical address.

Final Verdict: Safety First, Savings Second

While DIY can save money in minor cases, sewage cleanup is one home project where cutting corners can cost you way more in the long run—financially and health-wise. When in doubt, call a pro.

FAQs

Q1: Can I save belongings contaminated by sewage?

A: It depends on the material and level of contamination:

  1. Non-Porous Items: Glass, metal, or plastic can often be disinfected with a bleach solution.
  2. Porous Items: Mattresses, carpets, stuffed toys, and drywall usually need to be discarded. Sewage seeps deep into these materials, making them impossible to fully sanitize.

When in Doubt:

  • Consult a professional restoration company.
  • Prioritize safety over sentimental value—exposure isn’t worth the risk.

Q2: Can pets stay in the house during sewage cleanup?

A: It’s best to relocate pets until the area is fully sanitized and dry. Animals are vulnerable to:

  1. Chemical Exposure: Cleaning agents like bleach can harm pets.
  2. Pathogens: Pets can ingest or inhale contaminants while grooming.

 

Temporary Solutions:

  • Keep pets in an unaffected room with closed doors.
  • Use baby gates or crates to restrict access.

Q3: How do I prevent future sewage backups?

A: Proactive maintenance reduces risks:

  • Avoid Flushing Non-Flushables: Wipes, feminine products, and grease clog pipes.
  • Install a Backwater Valve: Prevents sewer lines from backing into your home.
  • Inspect Sewer Lines Annually: Hire a plumber to check for tree root intrusions or cracks.
