Frequently Asked Questions

Is septic tank cleaning environmentally safe?

Yes, when handled by licensed professionals. Waste must be contained, transported and disposed of at approved facilities to prevent contamination of soil and waterways.

Equipment is sealed to avoid spills, and strict procedures are followed to protect public health and the environment. Choosing a compliant provider is essential for responsible septic management.
What should I do before my septic tank is cleaned?
Before your appointment:
- Clear any access paths to the tank
- Locate the lid if possible
- Keep pets and children away from the work area
If you're unsure where the tank is, the technician can help find it on arrival, but any prep work saves time and makes the job easier.
Can septic cleaning fix bad smells?

Yes, in many cases. Odours are often a sign of excessive sludge, poor drainage or a full tank—all of which are resolved during a proper cleanout.

If smells persist after cleaning, further inspection may be needed to check for venting issues or system damage. But cleaning is usually the first and most effective step.
What time of year is best to clean a septic tank?

Septic tanks can be cleaned year-round, but drier weather is often ideal. Wet soil can make access more difficult and increase the risk of tank flooding.

Scheduling ahead—especially before rainy seasons or busy periods—ensures the job can be done quickly and safely, without weather-related delays.
