Common Questions

What should I do if I suspect a leak in my underground sewer line?

If you notice soggy patches in your yard, foul odors, or frequent drain backups, you may have a sewer line issue. As a family business with generations of experience, we specialize in sewer repairs and inspections. We use specialized camera equipment to locate the exact problem without unnecessary digging, then provide a clear explanation and solution, whether it's a repair or a full replacement. Early detection can prevent more extensive damage to your property.

My HVAC system is running but some rooms are never comfortable. What's wrong?

This is a common issue in Ontario homes, often caused by duct leakage, which reduces airflow to certain areas. We perform thorough HVAC inspections to identify leaks, poor insulation, or blockages in your ductwork. Our repair service seals these leaks to restore balanced airflow and improve system efficiency, which can also enhance your indoor air quality by preventing dust and contaminants from being pulled into the ducts.

Why is my garbage disposal humming but not grinding?

A humming disposal usually means the motor is running but the impellers are jammed, often by a foreign object. For safety, always turn off the power at the circuit breaker first. You can often use a special hex key (usually provided with the unit) to manually turn the impellers from the bottom and dislodge the item. If that doesn't work, the motor or internal components may need repair. We offer garbage disposal repair and replacement services to get your kitchen back in working order quickly.
