Septic Tank & System Repair

Between a routine pump-out and a full system replacement sits everything else that goes wrong with a septic system — and most of it is small. A baffle that rotted through. A pump that quit. A lid that cracked. A buried access point that costs you a digging fee every single visit. This is the page for that work across the City of Kawartha Lakes.

Most septic repairs run $200 to $800. That range is doing a lot of honest work in a trade where the scary quote is a sales tactic: the majority of "failing septic" calls we see end in a component repair, not a replacement. We diagnose before we replace — if a $200–$500 baffle is the fix, that is the quote, not a new system.

What We Repair

• Inlet and outlet baffles — $200 to $500. The tank's most failure-prone part, especially in older concrete tanks where original concrete baffles erode away. A failed outlet baffle lets solids reach the leaching bed, which is how a $300 repair deferred becomes a $10,000-plus bed problem. The warning signs are visible at every pump-out — which is one more reason to be there when the tank is open.
• Effluent and lift pumps — $600 to $1,500. Any system that pumps uphill has one, they last 7 to 10 years, and they announce their death by alarm — usually on a long weekend. What replacement involves, including why the float switch matters as much as the pump.
• Effluent filters — $50 to $150 to replace, routinely cleaned as part of a pump-out. The cheapest insurance the bed has. Systems permitted before filters were standard can often have one retrofitted — worth asking about while the tank is open.
• Tank lids — $100 to $300. A cracked, spalling, or improvised lid is not a cosmetic problem; lid collapses are how people and pets end up in tanks. If yours is a sheet of plywood or a patio stone, replace it this season. Why this is the one repair not to defer.
• Risers — $200 to $500 installed. The upgrade that ends digging forever: the access point comes to grade, the $100–$200 digging fee disappears from every future pump-out, and winter service stops requiring an excavation through frozen ground. How risers work.
• Lines and distribution box. Root intrusion, a crushed section between tank and bed, a d-box distributing to one run instead of all of them — mechanical problems with mechanical fixes, diagnosed by camera where it helps and quoted once we can see what we are dealing with.

Tank Side or Bed Side?

Everything above is hardware — parts that can be reached, replaced, and priced. The other half of the system is the leaching bed, and it plays by different rules: beds are not repaired part-by-part, they are diagnosed, rehabilitated, or replaced. If your symptoms live in the yard — soggy ground over the bed, a stripe of suspiciously green grass, effluent surfacing — start at drain field and leaching bed repair instead. If the whole system is at the end of its life, that conversation is installation and replacement.

Not sure which side your problem is on? That is normal — slow drains and smells can come from either. Call (705) 702-5526 and describe it, or book a septic inspection and get the whole system looked at once, properly.

Repair or Replace? Age Does the Math

The part is rarely the whole question. A new baffle in a 12-year-old tank is easy money well spent. The same baffle in a tank pushing 40 is a harder conversation, because concrete tanks last 30 to 40 years — and a new part bolted to a nearly-done tank is rent, not a fix. Steel tanks are the extreme case: 15 to 20 years of lifespan means nearly every steel tank still in the ground around here is past due, and corrosion holes are not repairable. If your place is an older farmhouse or cottage and nobody knows what is down there, old farmhouse septic is worth ten minutes.

Our rule runs both directions. We will not quote you a system when a part fixes it — and we will not sell you a part when the component it attaches to is finished. Either way you hear the reasoning, the numbers for both paths, and the honest recommendation before anything is decided.

Repairs Rarely Need a Permit. Modifications Do.

Restoring an existing component to its designed function — baffle, lid, filter, pump swap, riser — generally requires no permit. Changing the system does: replacing the tank, replacing the bed, adding a treatment unit, or adding capacity to the house all trigger a sewage system permit under Part 8 of the Ontario Building Code. A few jobs sit in a genuine gray zone, and near the lakes a Conservation Authority layer can apply — where it is ambiguous, we ask the City first rather than guessing with your property. The full decision table is in do I need a permit to repair or modify my septic system.

When It Cannot Wait

Sewage backing up into the house, an alarm you cannot silence, or septic smell indoors is not a book-a-repair situation — that is emergency septic service, with same-day or next-morning response. Run as little water as possible and call. Repairs that surface during an emergency call get stabilized first and quoted properly in daylight, not priced under pressure.

Start With the Symptom

Call (705) 702-5526 and tell us what you are seeing — the smell, the sound, the alarm, the wet patch — and roughly how old the system is if you know. Most of the time we can tell you the likely culprit and the realistic cost range before the truck leaves the yard. And if the answer is "your tank is just overdue," you will hear that too: a pump-out with eyes on the baffles and filter is the cheapest diagnosis in the business.
