Guelph's 24/7 Sewage Backup Cleanup Team
Guelph's downtown and older wards are built of local limestone around two rivers, with university-area rentals and newer south-end subdivisions around them.
We take sewage backup cleanup calls across Guelph, including Exhibition Park, The Ward, Old University and Kortright Hills.
The 2021 Census counted 143,740 people and 56,480 occupied homes in Guelph.
20% of them were built in 1960 or before and 44% before 1981, while 30% have gone up since 2001. A house of the older group may still have some of its original supply lines and drains, so the build date is one of the first things we ask about.
68% are single-detached, semi-detached or row houses, where the owner is responsible for the foundation, the drains and the sewer lateral. 12% are apartments in buildings of five or more storeys, and a further 20% are in low-rise buildings or duplexes. There, a leak commonly reaches the units below and involves the landlord or condominium corporation.

What Sewage Backup Cleanup Costs in Guelph
This work is priced on what is damaged and how far it has spread, so it is assessed before it is quoted. There is no flat rate, and anyone offering one over the phone has not seen the job. Here is how the cost is set and who pays.
| Situation | What you pay | Details |
|---|---|---|
| Insured loss | Your deductible | Your insurer pays the approved scope. We document the damage and deal with your adjuster. |
| Not insured, or not claiming | Written estimate before work | Emergency steps to stop the damage start on your say-so. Everything after that is priced first. |
| Upgrades during the rebuild | You pay the difference | Insurers pay like for like. Better finishes are priced separately so the claim stays clean. |
| Emergency call-out | Ask when you call | We tell you about any call-out charge before a crew is sent. |
We have not confirmed a current municipal subsidy for backwater valves or sump pumps in Guelph. Ask the municipality before paying for flood-protection plumbing, because programs change.

What makes sewage different
A sewage backup is classed as the most contaminated kind of water loss. It carries bacteria, viruses and parasites from human waste, and during storms it also carries whatever has washed into the sewer system. The health risk comes from contact and from contamination being tracked or splashed onto other surfaces.
That is why the rule for sewage is removal, not drying. Porous materials absorb contaminated water into places that cleaning products cannot reach. Carpet, underpad, drywall, insulation, particleboard and upholstered furniture that were in contact with sewage are taken out. Concrete, framing lumber and other structural materials are cleaned, disinfected and then dried.
Backups have two broad causes. One is a problem in the building's own drain or lateral. The other is the municipal sewer running full during heavy rain and pushing back toward the house. Knowing which one you had matters for preventing the next one and can matter for your insurance claim.
What to expect on the first visit
The crew arrives in protective equipment and starts by setting limits: which rooms are affected, where the contamination stops and how people can move through the house without tracking it. The affected area is isolated before any material is disturbed. If the backup is still active, nothing is flushed or drained until the cause is understood.
Sewage and solids are removed first, then the porous materials that were in contact with it. That usually means carpet, underpad, baseboard and the lower part of the drywall and insulation on the first visit. Hard surfaces are washed and then disinfected. Only after that does drying begin. You should be told clearly which belongings can be cleaned and which cannot be made safe.
What we do in Guelph, in order
- 01
Contain the area
We isolate the affected rooms so contamination is not tracked through the house.
- 02
Remove sewage and solids
Liquid is extracted and solids are removed and disposed of properly.
- 03
Remove porous materials
Carpet, underpad, drywall, insulation and other absorbent materials that contacted sewage are bagged and removed.
- 04
Clean and disinfect
Hard surfaces and structural materials are washed, then disinfected.
- 05
Dry the structure
Drying equipment runs until moisture readings are back to normal.
- 06
Rebuild
Finishes are reinstated once the area is clean and dry.
Why sewers back up
- Municipal sewer surcharge
- In an intense storm, more water enters the sewer than it can carry, and the level rises above basement floor drains.
- Combined sewers
- Older parts of some Ontario cities carry stormwater and sewage in one pipe, which fills quickly in heavy rain.
- Tree roots
- Roots enter clay or cracked laterals at the joints and grow into a mat that catches paper and solids.
- Grease and wipes
- Fat poured down the sink hardens in the pipe. Wipes labelled flushable do not break down the way toilet paper does.
- Collapsed or sagging lateral
- Old clay and cast iron pipes crack, shift and settle, creating low spots where solids build up.
- Weeping tile connected to the sanitary sewer
- In some older homes the foundation drain discharges to the sanitary line, adding rainwater to it. Several municipalities subsidise disconnecting it.
What can be kept after a sewage backup
| Concrete and masonry | Washed, disinfected and dried. |
|---|---|
| Framing lumber | Usually cleaned, disinfected and dried in place once wall coverings are removed. |
| Drywall, insulation, carpet, underpad | Removed and disposed of. |
| Solid wood and metal furniture | Usually cleanable. Upholstered furniture and mattresses are not. |
| Appliances | Assessed individually. Insulated appliances such as fridges and freezers that sat in sewage are often written off. |
| Clothing and linens | Hot-water laundering with disinfectant can save washable items. Heavily soiled items are discarded. |
How long it takes
Removal and disinfection are normally completed in the first one to two days. Drying follows, then rebuild.
Insurance
Sewer backup is usually not part of a basic home policy in Ontario. It is commonly sold as an optional endorsement with its own limit and deductible. If you have it, the cleanup, drying and repairs are typically what it responds to. Check your declarations page or ask your broker.
This is general information, not advice on your policy. How restoration claims work.
Mistakes to avoid
Using a shop vacuum and bleach. This spreads contamination into the air and leaves it inside every porous material. It also exposes the person doing it.
Keeping the carpet. Steam cleaning does not make sewage-soaked carpet or underpad safe.
Running the furnace fan. If the return air is in the affected area, the system can distribute contamination and odour through the house.
Skipping the municipal report. If the city sewer was the cause, the municipality needs to know, and your report is useful evidence for your insurer.
Questions worth asking any contractor
Whoever you hire, including us, should be able to answer these plainly.
- Which materials are you removing, and which are you cleaning and keeping?
- How do you keep contamination from spreading to the rest of the house?
- What disinfectant is used, and is the space safe for children and pets afterwards?
- Should the sewer lateral be inspected by camera before the basement is rebuilt?
- Will your report record the cause, for my insurer and the municipality?
Preventing another backup
- Install a backwater valve on the sanitary lateral, and check whether your municipality subsidises it.
- Have the lateral inspected by camera if the home is older or has large trees near the line.
- Never pour grease down the drain, and do not flush wipes, even those sold as flushable.
- Disconnect downspouts and weeping tile from the sanitary sewer where they are connected.
- During intense rain, hold off on laundry, dishwashers and long showers if you have a backwater valve.
Sewage Backup Cleanup in Guelph: common questions
Do you provide sewage backup cleanup in Guelph at night and on weekends?
Yes. Calls from Guelph are answered at any hour, every day of the year, and a crew is dispatched when the situation needs one.
Is there a basement flooding subsidy in Guelph?
We have not confirmed a current municipal subsidy for flood-protection plumbing in Guelph. Programs change, so ask the municipality directly before paying for a backwater valve or sump pump.
Do you work with insurers on losses in Guelph?
Yes. We document the damage with photos, readings and an itemised scope and deal with your adjuster. Coverage decisions are your insurer's, and in Ontario you can generally choose your own restoration contractor.
Which parts of Guelph do you cover?
All of it, including Exhibition Park, The Ward, Old University, Kortright Hills. Exhibition Park: North of downtown around a park dating to 1871, with many houses more than a century old.
Who do I call about a sewer backup in Guelph?
When a sewer backs up in Guelph, the City asks property owners to call its wastewater services at 519-837-5629 so that staff can check the City sewer.
Can I clean up a sewage backup myself?
We advise against it for anything beyond a very small spill on a hard surface. Sewage carries bacteria, viruses and parasites, and porous materials cannot be reliably disinfected. Without removal of those materials the contamination and smell remain.
Who is responsible, me or the city?
In general the homeowner is responsible for the sewer lateral on their property and the municipality for the main. Responsibility for damage is a separate question and depends on the cause. Report the backup to your municipality and your insurer.
What can be saved after a sewage backup?
Hard, non-porous items can usually be cleaned and disinfected. Carpet, underpad, upholstered furniture, mattresses, drywall and paper goods that were in contact with sewage are normally discarded.
Will the smell go away?
Yes, once the contaminated materials are removed and the structure is cleaned and dried. Odour that lingers is a sign something contaminated is still in place.
What illnesses can sewage cause?
Sewage can carry organisms that cause gastrointestinal illness, skin infections and other conditions. Children, older adults, pregnant women and people with weakened immune systems are most at risk. If anyone develops symptoms after contact, speak to a health professional and mention the exposure.
How long does a sewage cleanup take?
Removal and disinfection of an average basement area is commonly done within the first one to two days. Drying follows over several more days, and then the rebuild is scheduled.
Does the house need to be evacuated?
Not always. If the backup is confined to an unfinished basement that can be closed off, many households stay. If living space is affected, or there are vulnerable people in the home, staying elsewhere until cleaning is complete is the safer choice.
Can I claim against the city?
Municipalities are generally only liable where negligence can be shown, and there are short notice periods for claims against a municipality in Ontario. Report the backup promptly and get legal advice if you intend to pursue it. Your own sewer backup coverage is usually the faster route.
How do I stop it happening again?
A backwater valve on the sanitary lateral is the main protection against municipal surcharge. A camera inspection will show whether roots or a damaged pipe caused a private-side blockage. Disconnecting downspouts and weeping tile from the sewer reduces the load.
