Lyndsay at Clarington Septic is very professional, they showed up as promptly as was possible, they completed the work in a very timely fashion. They designed an effective system given the limited space within the budget they promised and came back in the spring to complete the landscaping as per the contract. I highly recommend them.

Lyndsay, Claude and Andrew were just amazing and really take pride in every aspect of their work. We needed an entirely new septic system and winter was fast approaching, I was in a panic thinking it could never be completed at this time of year. Boy was I wrong. We reached out to Clarington Septic Repair, and it was the best call we made. Communication was always prompt and informative. It was a great comfort to us that all of the permits, designs, inspections and plumbing were arranged by Lyndsay, and she was able to co-ordinate it all so beautifully. These friendly folks were a joy to be around and always had time to answer questions, keep us in the loop or just have a few laughs.

This is an amazing company, I was freaking out when I couldn’t find anyone to repair my septic system lids, no one was calling me back. Lyndsay from Clarington Septic did! She texted me back within a couple hours of leaving a message and inspected my tank the next day. I was concerned they couldn’t repair due to my lid openings being warped, but she was able to put together a plan. Her, Andrew and Claude showed up the following week and I had beautiful green lids in no time !! Super happy, thank you Lyndsay and team! Dave

3 Things You Need To Know About Your Septic
Regular Maintenance is Extremely Important
A lot of people think you never have to pump your septic tank—but that’s just not true. It’s super important to have it pumped every 3–5 years. If you don’t, you’re risking backups and major repairs.
Water Usage Does Matter!
Water usage plays a big role in how well your septic system works. Using too much water can overload it. If you notice any leaking faucets or toilets, fix them right away—they can cause major issues over time.
Always Do Septic-Safe Practices
Practicing septic-safe habits helps extend the life of your system. Only flush toilet paper—no wipes, grease, or harsh chemicals. Spread out laundry loads, use water efficiently, and avoid driving over your bed or tank to prevent damage.

Issues With Your Septic?
Lack of Maintenance
Inadequate pumping and maintenance can lead to the accumulation of solids in the septic tank, causing blockages and system failure. It's advised to get your septic tank pumped every 3-5 years.
Overloading
Excessive water usage, especially in a short period, can overwhelm the system, preventing effective treatment and leading to issues. Overloading can also mean leaking toilets, water or iron softeners, or more people living in the house.
Damage to Drain Field
Compaction, root intrusion, or physical damage to the drain field can hinder proper wastewater absorption, resulting in system failure.
Biomat Buildup
Biomat slowly builds up over time in your septic bed as wastewater is filtered. If can clog the system and prevent your septic bed from draining properly.
