Sewage Backup Cleanup in Toronto
A sewer backup can send dirty water into a basement, bathroom or utility room very fast. It may also reach floors, walls, cabinets and stored items. GTA Restoration provides Sewage Backup Cleanup in Toronto for homes, condos, rental properties and businesses.
Our team removes sewage water and checks where it has spread. We also clean hard surfaces that can stay in place. In addition, we dry wet areas and check for hidden water under floors or behind walls.
Most importantly, keep people and pets away from sewage water. It may contain harmful germs. For more safety information, read Health Canada’s flood cleanup guide.
Emergency Sewage Cleanup Toronto: First Steps
Keep People Away From Dirty Water
First, keep children, pets and other people away from the wet area. Sewage water can carry germs. Therefore, avoid direct contact until cleanup starts.
Watch for Electrical Risks
Water near outlets, appliances or electrical panels can be dangerous. For this reason, stay out of the area if you are not sure it is safe.
If water has reached electrical equipment, contact a qualified electrician or utility provider for help.
Stop Using Drains During a Sewer Backup
Next, avoid flushing toilets or running sinks during an active sewer backup. Using more water may send more sewage into the basement or another low area.
The City of Toronto gives similar advice in its basement flooding guide.
How Sewer Backup Cleanup Toronto Works
Find the Source of the Backup
Cleanup will not fix a blocked sewer line. Therefore, a plumber may need to find the cause before the problem returns.
For example, tree roots can enter a pipe. Grease and other waste may also cause a clog. In other cases, an old pipe may crack or break.
For urgent plumbing problems, visit our emergency plumbing service.
Sewage Water Removal During Cleanup
Once the area is safe, crews can begin sewage water removal. Fast extraction helps clear standing water so the next part of the cleanup can begin.
During Sewage Backup Cleanup in Toronto, our team also checks nearby rooms. Dirty water may travel farther than the visible spill.
Check Wet & Damaged Materials
Sewage can soak into drywall, carpet, insulation and other soft materials. As a result, some items may not be practical to keep.
However, hard surfaces may often allow proper cleaning. Our team checks the condition of each area before moving ahead.
Clean After a Sewer Backup
After water removal, crews remove dirt and sewage waste from surfaces that can stay. Next, we clean those areas with suitable products.
Sewage cleanup should deal with the dirty water as well as the waste it leaves behind.
Drying After Sewer Backup Cleanup Toronto
Removing standing water does not mean the property is dry. Water may remain below floors or inside walls.
Therefore, our team may use air movers and dehumidifiers after cleanup. We also check moisture levels as the area dries.
This step matters because wet materials can support mould growth. For larger drying jobs, visit our specialty drying service.
Hidden Damage After Sewage Backup Cleanup Toronto
Water Under Floors & Behind Walls
Dirty water can move through small gaps and hidden spaces. For example, it may travel under flooring or behind baseboards.
As a result, the visible wet area may not show all the damage. Professional sewer backup cleanup should also check nearby wet areas.
Sewer Odours After Sewage Cleanup
A strong smell may remain if wet or dirty materials stay in place. Therefore, finding the source of the odour is an important part of the job.
In some cases, crews may need to remove damaged items or clean hidden areas before the smell improves.
Mould After Sewage Cleanup Toronto
Mould can grow when building materials stay wet. For this reason, drying should begin as soon as the area is safe and clean.
If visible mould appears, visit our mould removal and remediation service.
Common Causes of Sewer Backups
A sewer backup can happen for several reasons. Some problems start inside the property, while others may involve the sewer system outside.
Blocked Sewer Lines
Grease, wipes and other waste can build up inside a pipe. Over time, the blockage may slow the flow and cause water to back up.
Tree Roots & Broken Pipes
Tree roots may enter damaged sewer lines. In addition, older pipes can crack or fail over time.
Heavy Rain
Heavy rain can place more pressure on sewer systems. As a result, some properties may face a higher risk of basement flooding or sewer backup.
The City of Toronto provides more information about blocked and backed-up basement drains.
Help Prevent Another Sewer Backup
After cleanup, find out why the problem happened. A plumber may need to check the drain line, sewer pipe or backwater valve.
Also, avoid putting grease, wipes and other waste down household drains. Proper drain care may help lower the chance of another blockage.
Toronto homeowners can also review the City’s basement flooding information for ways to reduce flood risk.
