What To Do After A Sewage Back Up

Sewage backup in a house is one of those unfortunate events that can certainly ruin your day as well as your entire week, your habitual daily routine, and even your household items.

Depending on the severity of the problem, you may lose from several hours (locating the cause of the backup, eliminating it, and cleaning the mess) to several days (not being able to use your home until water damage mitigation is over).

Besides the obvious inconveniences, sewer backup may pose great risks to your health and may turn out to be a considerable drain on your budget, especially if your insurance doesn’t cover such problems and you need to pay for all the repair works and to replace damaged furniture or appliances.

However, you can avoid the trouble altogether or at least limit the damage, if you know the right steps to take after a sewage backup.

What Causes Sewage Backup

Backups usually result from problems in the sewer systems or the septic systems treating domestic wastewater.

The typical reasons for a sewage backup fall in three main categories:

  • Clogging. Sewage backups are common occurrences when a sewer line is clogged. If you experience a problem with just one toilet, sink, or tub, there is probably a clog in its particular drain and appropriate drain cleaning will resolve the issue without further repercussions. If, however, every flush creates a sewage backup in your home, the situation is much more troublesome – it means that the main sewer line is blocked. A blockage in the private or main sewer causes a backup through floor drains and toilets at the lowest point in your property, resulting in sewage backup in basements first. Unless the blockage is removed, the overflow will continue and will damage your entire home or business area;
  • Tree Roots. Although it is somewhat hard to believe, the roots of large trees in the proximity of a sewer line can often cause severe problems. They can literally grow into the pipes and cause holes and blockages or they may wrap around the sewer line and crush it;
  • Damaged Sewer Lines. If your property is old and the plumbing and sewer systems have not been recently renovated, your sewer backup may be caused by broken, cracked, or collapsed lines. All the pipes and sewers in older homes were built using cast iron and clay which can wear off with time, get rusty, and easily break down. Present day plastic sewer lines cannot cause such problems simply because they don’t rust.Blockages in the private or main sewer lines can cause a backup in your home or office.

Risks Posed by Sewage Backup

Leaving aside all the repulsive dirt and smell involved in a sewage backup, the problem can cause much greater harm if not addressed timely and properly.

Health Hazards

Water contaminated with sewage usually contains a variety of bacteria, viruses, and germs that are harmful to your health.

You can experience vomiting and diarrhea or even contract Hepatitis A if you consume contaminated water or food.

You can also get sick if you use items that have been in contact with the sewage without disinfecting them properly first (the viruses are not transmitted through the air but the contaminated pieces can easily get in touch with consumables, kitchen utensils, medicines, toiletries, etc.).

Have in mind that touching such articles with bare hands can cause skin irritation or infection, especially if you have cuts or sores.

Fire Hazards

If the water level has reached any plugs, electrical outlets, extension cords, or gas-burning equipment, do not touch anything!

Get out of the building immediately and call the professionals as the risk of a fire is enormous.

If all your electrical equipment as well as the distribution panel is still safely above water, switch off the power as soon as you detect the problem.

Let safety be your top concern: wear rubber boots, make sure that you are standing on a dry surface and that you are not touching anything made of metal (pipes, ladder, etc.), stand on a wooden stool or chair (dry wood is not a good electrical conductor), and shut off the main switch with the help of a dry wooden stick or at least – rubber gloves.

Property Damage

If your property remains under sewage water for long, the damage will be considerable.

Be aggressive in locating the source of the mold and addressing it.

After all, nothing is more important than your health and the health of your family. Mold can become a serious issue very quickly if left untreated.

Flooring and insulation materials that have been soaked up can no longer be used, as well as mattresses, leather products, stuffed toys, and paper products (including books and documents).

Furniture that allows deep cleansing can be saved, as well as washable fabrics, but everything you decide to keep must be sanitized and cleaned properly.

Thats where PureDry Restoration can step in and help properly take care of the sewage damage so you can go on knowing you are safe.

We at PureDry® have 18 years experience of helping businesses get back on their feet quickly by using our specialized sewage remediation and disinfecting processes.

In fact, Pure Dry Restoration state of the art mold remediation equipment incorporates sanitizing treatments and air purification, thereby allowing us to clean damaged properties faster and safer than our competitors.

This increases the chances of restoring a property, rather than demolishing!

The risk of sewage backups is greatly reduced when you keep the drains in your property clean.

Sewage backup insurance may or may not cover the costs for the water damage restoration process and the expenses for the replacement of damaged household items, depending on the cause of the backup and other factors specific for each case and policy.

PureDry Restoration will help you navigate the insurance companies

We have years of experience navigating insurance companies. What is even better we help you through it.

Generally, if the reason for the problem is found to be your negligence (failure to properly maintain your drains, for example), you can’t expect any reimbursement.

If the blockage is due to roots from a tree in a public area or the pipe has collapsed on state property, the responsibility is not yours and you should be rightfully compensated.

We at PureDry Restoration will help you every step of the way from the first call to the insurance issues.

How to Prevent Sewage Backup

Proper sewage backup prevention measures can save you from a lot of trouble. So, you are advised to:

  • Regularly inspect and maintain all the pipes and valves on your property;
  • Keep the drains “clean” – don’t flush napkins, tissues, diapers, and other waste down the toilet and avoid disposing of grease down the kitchen drain (grease and fat can harden within the plumbing and collect debris to create a clog);
  • Avoid planting trees directly above or near sewer lines;
  • Have a sump pump in good working condition;
  • Have a backwater valve installed on the lowest drain line and keep the sewer clean-out in your yard accessible.

Go over your insurance policy to learn what your responsibilities are. Contact your agent for detailed information and ask about more beneficial coverage options.

In the event of a sewage backup, call the insurance immediately and take lots of photos to document the problem and the inflicted damages. Keep all the receipts for repair and cleaning works, as well as for materials and replacements.


A good restoration company can also help property owners decide if it’s best to make an insurance claim or pay for the water damage directly.

What to Do After Sewage Backup

If you take quick and efficient measures, you may limit the damage considerably.

1) Do not flush toilets or attempt to drain tubs and sinks – just don’t use the water supply system in your home until the problem has been detected and taken care of;

2) Do not use harsh chemicals in an attempt to unclog the draining system quickly and easily. They can damage your pipes and sewer lines and make the matters worse. Opt for treatment options which use enzymes instead of chemicals – they will most likely solve your problem and will prevent future clogging;

3) Keep children and pets away from the affected area;

4) If it is still safe, shut off the power. Otherwise, don’t go near electrical equipment;

5) Wear protective clothing: gloves, eyeglasses, rubber boots and a face mask.

6) Open windows to allow fresh air in and ventilate well to remove any fumes.

7) Use sump pumps to remove excessive water;

8) Call for professional assistance.

Remember that sewage backups should be dealt with as quickly as possible to prevent further damage.

How to clean up after sewage backup

Sewer cleaning is better left to the professionals but you can sanitize your own property if the sustained damage is not too extensive.

  • If dealing with a sewage backup, DON’T RUN FANS. This can spread dangerous contaminants throughout the property.  


We also provide safe sewage cleanup and sewage removal. Raw sewage is difficult to cleanup and can be extremely hazardous. 

Sewage can contain high amounts of harmful bacteria and there are serious health risks associated with it. It’s critical that you do not try to clean up the mess from broken pipes that are connected to a sewage line. 

Coming in contact with raw sewage can cause disease, can destroy your valuables and cause severe damage to your property.

Only trained professionals with the right equipment should handle sewage removal. Our team of professionally certified experts have years of experience resolving various sewage cleanup and repair problems.

  • Move furniture, electronics, and personal property to a safe location to avoid further water damage.
  • If applicable, remove curtains and anything else that touches the floor to avoid water damage.
  • Wash hands after ANY contact with standing water. Be sure all property occupants do the same. Tools, brooms, mops, etc. will need to be sanitized after use.


Property owners think they’re helping when they clean flood damage, but they’re destroying evidence that could impact a claim or get the claim denied altogether.

Instead of cleaning, follow the steps we’ve listed above.

Then, if it’s safe, take pictures of all property damage including personal items. 

Once all the sewage water is removed, you can follow these sewage backup cleanup tips if you think you do not need professional help:

Make sure your property is properly disinfected after a sewage backup.

  • Work from the top downwards to hose down any dirt sticking to walls and furnishings;
  • Wash intensively all surfaces and structures
  • Clean all the floors as quickly and efficiently as possible (replace flooring that has been deeply penetrated by sewage);
  • Discard sewage-soaked carpets. Wash and dry well any area rugs that have been only slightly affected and you intend to use them again. Clean and deodorize all carpets that have been in contact with sewage, however minor, or have them professionally cleaned;
  • Check for mold and use EPA approved sprays to kill any visible spores. Sanitize any cavities with the above described solution of water and chlorine bleach. Make sure that all structural elements are completely dry before closing cavities in walls, crawl spaces, and others;
  • Discard any soaked and dirty materials and debris, including wet insulation and drywall, residual mud and others;
  • Scrub slightly affected furniture pieces and appliances with antibacterial soap and water and let them air dry or steam them clean;
  • When washing contaminated clothes and bedding, add one cup of chlorine bleach to the water;
  • Throw out any consumable goods, including spices, herbs, etc. that may have been in contact with the sewage;
  • Discard anything that cannot be properly sanitized, such as stuffed toys and paper goods. Items of great sentimental or monetary value should be professionally cleaned and restored, if at all possible. Pieces that show no visible contamination pose a minimal risk and can be used again once they are properly disinfected and completely dry.

Before returning to your everyday life, make sure the entire property has been perfectly sanitized by a professional, the electrical and plumbing systems have been checked and fully repaired, and all the appliances are safe and in good working order.
