Sewage ("black water") carries bacteria, viruses and parasites — it's a health hazard, not a mess. Anything porous it touches (carpet, underpad, drywall, particleboard) is a removal, not a cleaning. Hard surfaces get cleaned, disinfected and verified.
Backups in Guelph usually trace to tree roots in older clay laterals (very common in the Ward, St. Patrick's Ward and other pre-1960s areas), grease blockages, or city main surcharges during heavy storms. We do the cleanup; a camera inspection of your lateral after the fact tells you whether it's going to happen again.
A toilet overflow of clean bowl water, maybe. Anything from a floor drain or main backup: no — it contaminates porous materials permanently and DIY cleanup is how people get sick.
Sometimes, if negligence is established — but don't count on it. Your own sewer-backup endorsement is what actually protects you. The City of Guelph also has a subsidy program for backwater valve installation.
A one-way flap on your sewer lateral that blocks city surcharge from entering your basement. If you've backed up once, it's the single best prevention investment — typically $1,500–$3,000 installed, with city subsidies available.
Cleanup and disinfection: 2–4 days. Rebuild of removed materials is a separate phase — we hand you a dried, disinfected, documented space ready for it.
