IICRC-Certified. Available 24/7. Fast, professional sewage cleanup for Calgary homeowners, handled safely from extraction to rebuild.
Call Red Dot Restoration the moment sewage backs up in your home. We'll respond quickly, contain the damage, and take care of everything so you don't have to.
A sewage backup is one of the most urgent situations a Calgary homeowner can face. Raw sewage is a Category 3 biohazard, meaning it contains bacteria, viruses, and pathogens that pose a genuine risk to your health and your home. Every hour it sits, the contamination spreads further into flooring, drywall, and structural materials, and what can be saved becomes less.
In Calgary, sewer backups spike during spring snowmelt and after heavy rainfall, when the municipal system is under pressure and private drain lines become overwhelmed. They also occur year-round due to blocked pipes, root intrusion, failed backwater valves, and overloaded floor drains.
At Red Dot Restoration, we provide certified sewage-backup cleanup in Calgary and the surrounding communities, available 24/7. Our IICRC-certified team arrives ready to extract, contain, decontaminate, and dry, and we work directly with your insurance adjuster from the first call. The sooner you reach us, the more we can save.
We respond 24/7 and arrive prepared to work immediately. Before anything else, we assess the extent of the contamination, identify the affected areas, and establish safety protocols. Sewage is a biohazard, and the work area is treated accordingly from the moment we arrive. We advise you on which areas of your home are safe to occupy while work is underway.
Using industrial extraction equipment, we remove all standing sewage water from your home as quickly as possible. Speed matters here because Category 3 contamination rapidly penetrates porous materials, and each hour increases the scope of what cannot be saved.
Porous materials that have been contacted by sewage, including drywall, insulation, flooring, carpet, and baseboards, cannot be cleaned to a safe standard and must be removed. We take a thorough but conservative approach, removing only what is genuinely contaminated, and document everything carefully for your insurance claim.
All remaining structural surfaces in the affected area are treated with professional-grade antimicrobial and disinfectant products to eliminate bacteria, viruses, and pathogens. This step is carried out methodically across walls, framing, subfloors, and any other surfaces within the contamination zone.
Once sewage has been removed and surfaces disinfected, industrial air movers and dehumidifiers are deployed to dry the structural materials. Moisture readings are taken and documented daily. Thorough drying is critical at this stage because any residual moisture left in the structure creates ideal conditions for mould growth.
Sewage odour is persistent and can embed itself in structural materials even after thorough cleaning. We use professional deodorization equipment and treatments to neutralize odour at the source, not mask it, ensuring the affected area is genuinely clean before we close up walls.
Once the space has been fully decontaminated, dried, and cleared, our in-house rebuild team restores it to pre-loss condition. From replacing drywall and insulation to new flooring, paint, and trim, we handle every phase of the restoration in-house, so you work with one team from start to finish.
Sewage backup situations in Calgary homes don't always look the same. Here are the situations we most commonly help homeowners with:
Calgary's spring season puts significant pressure on both the municipal sewer system and private drain lines. When snowmelt and rainfall volumes exceed the system's capacity, sewage can back up through basement floor drains, toilets, and utility sinks. This is the most common sewage backup scenario we see, and it tends to affect finished basements hardest. If water is coming up through your floor drain after a heavy rain, treat it as contaminated and call us immediately.
Tree roots are a major cause of sewage backup in Calgary, particularly in older, established neighbourhoods where mature trees have had decades to grow toward underground pipes. Roots infiltrate cracked or aging clay pipe joints and gradually restrict flow until a backup occurs. Grease buildup, flushed wipes, and foreign objects blocking the line are equally common culprits. Once the plumber has cleared the blockage, we handle the cleanup and restoration of everything the sewage touched.
A backwater valve is designed to prevent municipal sewage from flowing backward into your home during high-demand periods. When this valve fails, is absent, or has not been maintained, a surge in the city system can push directly into your basement. Homes built before the late 1980s in Calgary frequently lack this protection. If you've experienced a backwater valve failure, we can clean up and restore the damage.
A blocked toilet that overflows or a failed waste line inside the home can quickly contaminate flooring, subfloor materials, and wall cavities, especially on upper floors, where sewage travels downward through ceiling structures. Even what appears to be a minor overflow can involve significant hidden contamination. We assess the full extent of the damage, not just what's visible on the surface.
One of the first questions Calgary homeowners ask us after a sewage backup is: "Will my insurance cover this?" The answer depends on your specific policy, and sewer backup coverage works differently from standard water damage coverage in Alberta.
In Alberta, sewer backup is not typically included in a standard home insurance policy. It is generally available as a separate add-on rider. If you have this rider on your policy, it could cover sewage backup cleanup and restoration when the event resulted from a sudden and accidental cause, such as:
• Municipal sewer system overload backing up into your home
• A failed or overwhelmed backwater valve
• A blocked drain line caused sewage to back up into the home
• A waste line failure within the home
Sewer backups caused by lack of maintenance, a known recurring problem that was not addressed, or a drain line that was in a state of disrepair may be treated differently by your insurer. If you are not sure whether you carry a sewer backup rider, check your policy documents or call your broker before assuming you are not covered.
Red Dot Restoration has extensive experience navigating sewage-backup insurance claims with major Alberta insurers. Our team uses Xactimate, the industry-standard estimating software used by adjusters, so our documentation is in exactly the format your insurer expects. We:
• Help you understand whether your situation is likely to involve sewer backup coverage before we begin
• Document all contaminated areas and removed materials thoroughly with photographs and a written scope of work
• Provide a detailed inventory of what was removed and why, which is critical for your claim
• Communicate directly with your adjuster when needed
• Handle the paperwork so you can focus on your family and your home

Sewage backup cleanup in Calgary typically ranges from $5,000 to $10,000 for most residential situations, depending on the size of the affected area, the extent of contaminated material removal required, and the scope of rebuild work needed afterward. Finished basements with drywall, flooring, and contents in the contamination zone tend to fall at the higher end. Red Dot Restoration provides a full on-site assessment and written estimate before any work begins, so you have a clear picture of costs upfront.
Sewer backup coverage in Alberta is typically an optional rider added to your home insurance policy, not a standard inclusion. If you carry this rider, your sewage backup cleanup and restoration may be covered when the event is sudden and accidental. If you are not sure whether you have this coverage, check your policy documents or contact your broker. Red Dot Restoration works directly with insurance adjusters using Xactimate and can help you navigate your claim once we assess the damage.

The emergency extraction and decontamination phase typically takes one to two days. Structural drying that follows usually runs three to five days, depending on the extent of the damage and the materials involved. Rebuild and restoration after drying can take additional time, depending on the scope. We provide a clear timeline after our initial assessment so you know what to expect at every stage.
It depends on the extent of the contamination and which areas of your home are affected. If the backup is contained to an unfinished basement area that can be fully isolated, remaining in the upper floors may be possible. For larger contamination events involving finished living spaces, strong odours, or widespread material removal, temporary relocation is advisable for health and comfort. Your insurance policy may include Additional Living Expenses coverage for temporary accommodation in these circumstances, and we can help document this as part of your claim.
Category 3, sometimes called black water, refers to water that is grossly contaminated and contains harmful bacteria, viruses, and pathogens. Sewage backup is always treated as Category 3, regardless of its appearance, because even clear-looking sewage can carry significant contamination. This classification determines the required cleanup protocol and which materials can be safely saved and which must be removed. Attempting to clean Category 3 contamination with household products is not effective and can be hazardous to your health.
For very minor situations on non-porous concrete surfaces with no standing water and no porous materials affected, some limited self-cleanup may be possible using appropriate protective equipment and commercial-grade disinfectants. However, for any backup involving porous materials such as drywall, carpet, underpad, or wood, professional cleanup is strongly recommended. Improper cleanup of Category 3 contamination leaves behind pathogens invisible to the naked eye, resulting in ongoing health risks and mould growth.
Yes. For certain moderate-risk and high-risk asbestos abatements in Alberta, a Notice of Project must be filed with Alberta OHS before work begins. This is a regulatory requirement for specific scopes of work. Red Dot Restoration manages this filing as part of our abatement process so your project is compliant from the start.
Yes, and in many cases it needs to be. When water damage or fire damage occurs in a home built before 1990, asbestos-containing materials are often disturbed or compromised as part of the event. Abatement must be completed before restoration and rebuild work can proceed in the affected area. Because Red Dot Restoration handles both abatement and full restoration in-house, we coordinate these phases seamlessly, reducing delays and giving you a single point of contact throughout the project.
