Two properties on the same road can get quotes $10,000 apart. This tool shows you why — scope, soil, removal, and the permit-and-design costs that some quotes leave out — and gives you an itemized range for a replacement in Kawartha Lakes.
Answer five questions. The result is an itemized range, not a single number — because nobody can give you a single number before a site visit.
Tight access shown as the upper half of the range. Smaller equipment and more hand work take longer. We quote it up front after the site visit — it is never added after the job.
BEFORE YOU ACCEPT A NUMBER LIKE THIS
Estimate only. Every installation or replacement starts with a site visit and ends with a written, itemized quote. The price changes only if the scope changes — and we tell you before any extra work happens, not after.
We diagnose before we replace. If a $200 to $500 baffle is the fix, that is the quote — not a new system.

The single biggest factor. Sand that drains gets a conventional bed. Clay, thin soil over Shield rock, or a high water table forces a raised mound — and the imported sand, trucking, and grading are why that range starts at $25,000.
A sound tank can stay. Replacing the bed alone runs $10,000 to $25,000; tank and bed together start at $15,000. And a bed that is clogged but structurally sound may only need a $3,000 to $10,000 rehabilitation.
The CKL permit, a licensed designer, the perc test, and the test pits are all real line items — $3,000 to $7,000 before a shovel moves. A $16,000 quote that leaves them out is a $22,000 quote.
Pulling a concrete tank and hauling out old bed material adds $1,500 to $3,000. Steel tanks from the 1970s and 80s may have partly collapsed, which makes removal messier.
A full-size excavator and dump truck at the work area keeps the job fast. A narrow laneway, a slope, or a bed behind the garage means smaller machines and more hours. Quoted up front, never added after.
Spring and summer are peak season. Late fall often has more availability. Winter installs are possible but frozen ground costs more, and nobody perc-tests frozen soil — plan soil work for late spring through fall.
A full septic system replacement runs $15,000 to $35,000 in Ontario, with most jobs landing between $15,000 and $30,000. A conventional tank-and-tile-bed system on good soil is the low end at $15,000 to $22,000. Shallow soil, clay, or a high water table pushes you to a raised mound at $25,000 to $45,000, and a small or waterfront lot that needs a tertiary treatment unit runs $28,000 to $45,000.
Replacing the leaching bed while keeping a sound tank runs $10,000 to $25,000. If the bed is structurally sound but clogged by biomat, rehabilitation at $3,000 to $10,000 can sometimes save it — an inspection tells you which situation you are in.
In the City of Kawartha Lakes the septic permit runs $500 to $800, a licensed sewage system designer $1,500 to $3,500, a perc test $500 to $1,500, and a soil profile or deep test pit $500 to $1,000. Permitting and design for a Class 4 replacement typically total $3,000 to $7,000 before a shovel touches the ground.
Often not. We diagnose before we replace. A cracked baffle, a failed effluent filter, or a collapsed distribution pipe produces the same symptoms as a dead bed, and general repairs run $200 to $800. A septic inspection at $150 to $500 is the cheapest step in the whole project, and it is the one that can save you five figures.
Replacing an existing system typically runs 4 to 8 weeks from first call to finished system. Permit review in Kawartha Lakes is usually 2 to 4 weeks for a straightforward application, and the excavation itself takes 2 to 5 days for most residential systems. Perc tests cannot be done on frozen ground, so plan soil work for late spring through fall.
Your estimate comes with the form. We call back within 24 hours on business days to set up the visit — and if the system can be repaired instead, we will say so.
