If you’ve discovered water in your basement, it’s likely from one of two sources: a sewer backup or a sump pump failure. While both can lead to serious property damage, they have different causes, risks, and solutions. At 247-365 Restoration, we’re here to help homeowners across the Greater Toronto Area and Lake Simcoe region understand the difference — and act fast when disaster strikes.
What Is a Sewer Backup?
A sewer backup happens when wastewater from the municipal system flows in reverse, flooding your home through floor drains, toilets, or sinks. This water isn’t just dirty — it’s dangerous. It’s filled with harmful bacteria, waste, and toxins that pose a serious health risk.
Common causes of sewer backup in Ontario include:
Overloaded municipal sewer systems during storms (especially in Toronto, Vaughan, and Richmond Hill)
Blocked or collapsed sewer lines
Grease buildup, tree roots, or non-flushable waste
Lack of a proper backwater valve
If you notice foul odors, slow drains, or water coming up from your basement floor, call a professional sewage cleanup company Innisfil immediately.
What Is Sump Pump Failure?
A sump pump is your basement’s first defense against rising groundwater. It collects excess water in a pit and pumps it safely away. When this system fails — especially during spring thaws or heavy rainfall — your basement is left vulnerable.
Top reasons sump pumps fail in the GTA and Simcoe areas:
Power outages (common during storms in Innisfil and Aurora)
A stuck float switch or mechanical failure
Clogged or frozen discharge pipes in winter
Overwhelmed capacity during flash flooding
Unlike sewer backups, this water is usually groundwater or rainwater. It may look cleaner but can still cause thousands of dollars in damage if not addressed immediately.
🛠 How to Tell the Difference
Not sure what type of flooding you’re dealing with? Here’s how to recognize the issue:
Sewer Backup: Smelly, dark water coming up from floor drains or toilets.
Sump Pump Failure: Clear or murky water rising from the sump pit or spreading across the basement floor.
Timing: Sewer backups usually strike suddenly, while sump issues may start slow and worsen with time.
Health Risk: Sewer water is a biohazard; sump water is less toxic but still damaging.
⚠️ Don’t Wait — Act Immediately!
Water damage — whether it’s from a sump pump system failure or a sewer line overflow — becomes more destructive by the minute. Within hours, it can ruin:
Drywall, flooring, and electrical systems
Furniture and personal belongings
Structural integrity of walls and subfloors
And within 48 hours — mold can take hold

Water damage restoration service involves the comprehensive process of repairing and restoring properties affected by water intrusion or flooding. This service encompasses various steps, starting from the initial assessment of the damage extent to the final restoration of the affected area. Professionals in this field utilize specialized equipment to extract water, dry out the affected surfaces, and mitigate further damage. They also address issues such as mold growth and structural damage caused by water. Additionally, water damage restoration experts work closely with insurance companies to streamline the claims process for homeowners or property owners. Overall, water damage restoration service aims to swiftly and effectively restore properties to their pre-damaged condition, ensuring safety, hygiene, and structural integrity.
The cost of water damage restoration can vary significantly depending on various factors such as the extent of the damage, the size of the affected area, the severity of the water intrusion, and the specific services required. On average, homeowners can expect to pay anywhere from a few hundred to several thousand dollars for water damage restoration services. Minor incidents like small leaks or localized flooding may cost less to address, while more extensive damage, such as widespread flooding or structural issues, can result in higher expenses. Additionally, the cost may also include expenses for water extraction, drying equipment, mold remediation, repairs to damaged structures or belongings, and any necessary renovations to restore the property to its pre-damaged condition. It's advisable to obtain multiple quotes from reputable restoration companies to get a better understanding of the potential costs involved based on the specific circumstances of the water damage.
When choosing a water damage restoration company, it's crucial to prioritize reliability, expertise, and responsiveness. Start by researching companies with positive reviews and certifications from reputable organizations like the Institute of Inspection, Cleaning and Restoration Certification (IICRC). Look for companies that offer 24/7 emergency services, as water damage requires immediate attention to prevent further harm. Ensure the company has experience handling similar types of water damage to your property and inquire about their process, equipment, and timeline for restoration. Request detailed estimates and compare pricing and services among different companies. Additionally, verify that the company is properly licensed, insured, and bonded to protect yourself and your property throughout the restoration process. By considering these factors, you can confidently select a water damage restoration company capable of effectively restoring your property to its pre-damaged condition.

Act fast. First, if possible, shut off the main water supply to prevent more water from entering the area. If there's a risk of electrical hazards, turn off the electricity to the affected zone—only if it’s safe to do so. Remove valuable or sensitive items like electronics, documents, and furniture from the area to minimize further damage. Then, immediately contact a professional water damage restoration company to assess the situation, begin water extraction, and prevent mould growth or structural issues.
The average water damage restoration process takes 3 to 5 days, but this can vary based on several factors:
Whether materials like drywall, flooring, or insulation need replacement
Drying and dehumidification typically take a few days, but repairs or reconstruction (if needed) may extend the timeline.
Delaying water damage cleanup can lead to serious consequences. Within 24–48 hours, mould can start to grow in damp areas, which poses health risks and worsens property damage. Prolonged exposure to moisture can warp flooring, weaken drywall, corrode wiring, and even compromise the structural integrity of your home. Insurance claims may also be denied if timely action isn’t taken.
It depends on the severity of the damage and the scope of the restoration work. If only a small area is affected and there's no contamination or mould risk, you may be able to stay—ideally in a different part of the home. However, if the damage involves sewage water, high moisture, or mould, or if drying equipment is noisy and runs 24/7, it may be safer and more comfortable to relocate temporarily until the area is fully restored.
Certified restoration specialists use advanced tools to detect water hidden behind walls, under floors, or in ceilings. These include:
Sewage backups are commonly caused by blockages in your home’s main sewer line. These blockages can result from flushing non-flushable items (like wipes or grease), buildup of debris, or tree roots infiltrating underground pipes. Sometimes, during heavy rainfall or flooding, municipal sewer systems become overloaded and force water back into homes. Old or damaged pipes can also collapse or crack, restricting proper flow and causing backups.
Sewage cleanup starts with the removal of all contaminated water using industrial-grade extraction equipment. Professionals then remove any damaged materials—like carpets, drywall, or insulation—that can’t be salvaged. After that, they deep-clean all surfaces with EPA-approved disinfectants to eliminate pathogens. Air movers and dehumidifiers are used to dry out the space, followed by sanitization to ensure it’s safe for occupancy. The entire process is done while wearing personal protective equipment (PPE) to prevent exposure.
Extremely dangerous. Sewage water—also called black water—contains bacteria, parasites, viruses, and other toxic substances. Exposure can cause illnesses like hepatitis A, salmonella, E. coli infections, skin rashes, and respiratory problems. Even airborne particles during cleanup can pose health risks. Immediate professional cleanup is critical to reduce the chance of contamination and long-term health issues.
Yes. Sewage water can seep into porous building materials like wood, drywall, and insulation, weakening them over time. If left untreated, this moisture can cause warping, rotting, and electrical hazards. Additionally, prolonged dampness creates the perfect conditions for mould growth, which further damages structural integrity and air quality. Quick remediation is key to preventing permanent damage.
No, it’s strongly advised not to attempt cleanup yourself. Raw sewage contains hazardous waste that poses serious health risks. Without the right protective gear, you could expose yourself to dangerous contaminants. Also, improper cleaning can make the situation worse or spread bacteria further. The safest option is to stay out of the affected area and call a licensed restoration team immediately.
