What They're Saying

Scott was the only professional, of 3 companies, who gave us options instead of suggesting the most expensive option (replacing a septic system). He took his time to walk our yard, and thoroughly explain the process while others gave a quick glance. We're happy with the job, and would recommend him 100%. Annabelle S.

I would highly recommend his company. Andrew W.

Called on a cold Sunday February morning with concerns of a backed up septic system. After a phone conversation and some very helpful direction we determined that my system was working correctly. My family and I sincerely appreciate the time you took to put our minds at ease. We definitely put your information on speed dial for next time! Jeremy P.

Frequently Asked Questions

How often should I pump my septic tank?

We recommend pumping your septic tank every 2 to 3 years, depending on the size of your household and the tank’s capacity. Regular pumping prevents backups, system failures, and costly repairs. If you’re noticing slow drains, foul odours, or standing water in your yard, your tank may already be overdue for service.

What are the signs that my septic system is failing?

Common warning signs of a failing septic system include:

Slow drains or gurgling sounds in plumbing fixtures.
Sewage backups into sinks, tubs, or toilets.
Foul odors around the drain field or septic tank area.
Lush, green grass or pooling water over the drain field (even during dry weather).
High nitrate levels in well water, which could indicate contamination.

If you notice any of these, contact a professional immediately to assess and resolve the issue.

Can I use household cleaners with a septic system?

Yes, but with caution. Moderate use of household cleaners is typically safe. We recommend avoiding:

Antibacterial products in large quantities (they can kill beneficial bacteria).
Bleach, drain openers, and solvent-based products used excessively.

Opt for septic-safe, biodegradable, or natural cleaners to protect your system’s balance.

What shouldn’t I flush or pour down the drain?

To avoid clogs and system damage, do not flush or pour:

Grease, fats, or oils
Flushable wipes, diapers, feminine hygiene products
Coffee grounds, food scraps
Paint, motor oil, solvents, or chemicals
Medications or antibacterial agents

Only human waste and toilet paper should go down the toilet.

Do you offer emergency septic services?

Yes, we provide 24/7 emergency septic services to address urgent issues like sewage backups, overflows, or complete system failure. Contact us immediately if you’re experiencing a septic emergency—we’re here to help day or night.

How do I locate my septic tank?

You can locate your septic tank by:

Checking your property records or inspection reports for a septic layout diagram.
Following plumbing lines from your home’s basement or crawlspace.
Looking for a slight mound or depression in the yard.
Using a septic tank probe or hiring a professional to pinpoint the location safely.

If you’re unsure, we can assist with locating your tank using specialized equipment.
