Find a Vetted, Licensed Septic Installer in Your Area
Ontario has hundreds of licensed septic system installers. A small number of them are excellent. A larger number are adequate. And a meaningful percentage — operating with valid licences but poor workmanship standards, inconsistent inspection habits, or a tendency to cut corners on materials — will leave you with a system that fails years before it should.

The part nobody tells you
Designers charge $800–$2,000 just for the paperwork in these quotes.
Ontario law lets you do that part yourself, on your own property. OntarioSepticDesigner.ca turns your answers into the same 26-page package the township clerk sees every day — calculations, drawings, forms, all of it.
Why Finding a Good Septic Installer in Ontario Is Harder Than It Should Be
The problem is that none of this is visible from a Google search, a Kijiji ad, or a yellow pages listing. A licence number tells you the person passed a qualifying exam. It does not tell you whether they pull their own permits, whether they show up on inspection day, whether they use proper materials, or whether their last three jobs are still functioning properly.
We built our installer network to solve this problem. Every contractor we refer has been screened on the criteria that actually predict good outcomes — not just a valid licence, but a track record of complete jobs, proper permits, honest quotes, and clients who would hire them again. When three of our installers contact you, you are not getting three random names from a directory. You are getting three people we would send to our own properties.
We receive a referral fee from installers in our network when a project is completed. We charge homeowners nothing. This means our incentive is to match you with someone who delivers a good outcome — a contractor who disappoints a referral does not get paid, and neither do we. Our network is maintained by outcomes, not by who pays to be listed.
How the Installer Match Works
Tell us your region, your situation type, your bedroom count, your timeline, and anything you know about your lot conditions. The more context you give, the more targeted the match. You are not committing to anything — this starts the matching process.
We review your submission and select three installers from our network who are actively working in your region, have relevant experience with your system type, and have current availability. For complex situations — failed perc tests, compliance orders, Class 4 systems — we match based on specialist experience, not just geography.
Before making any introduction, we brief each installer on your situation — lot conditions, system type required, bedroom count, any known complications, and your timeline. When they contact you, it is a substantive first conversation. You do not explain your situation three times to three strangers.
Each of the three matched installers contacts you directly — by phone or email based on your preference — to arrange a site visit and provide a quote. You are dealing with the installer directly, not through us. Our job is to make the right introduction and get out of the way.
You evaluate the three quotes, ask questions, check references, and choose the installer who is the best fit for your project. You are never obligated to use any of them. We stay available if you need help comparing quotes or reading contract terms — but the final decision is entirely yours.

How We Screen Every Installer in Our Network
We do not accept payment from contractors to be listed, and we have no minimum volume commitment — a contractor who stops delivering good work loses their place in the network regardless of how many jobs they have done for us. Here are the six criteria every installer must pass before their first referral and maintain to stay listed.
Sewage System Installation Certificate of Qualification verified directly at ontario.ca/collegoftrades — not accepted on the installer’s word. We check the licence number, confirm it is current, and re-verify periodically. An expired licence means immediate removal from the network.
Current Certificate of Insurance showing a minimum of $2,000,000 in general liability coverage — on file with us, not just verbally confirmed. We also confirm active WSIB coverage. A contractor who cannot produce either document on request does not enter or remain in the network.
References from completed jobs in your specific region within the past 12 months — not just a claim of regional coverage. Soil conditions, Health Unit processes, seasonal access, and local material availability vary significantly across Ontario. We verify regional experience, not just licence geography.
A demonstrated pattern of pulling their own permits, attending all required Health Unit inspections, and delivering Certificates of Completion on every job. We ask for references specifically on inspection compliance — skipping inspections is one of the most common and damaging patterns we screen for.
Contractors who consistently provide fully itemised written quotes — breaking out every cost component separately so homeowners can make real comparisons. We specifically screen for the pattern of low all-in quotes that exclude soil testing, permit fees, or site restoration — a disqualifying habit.
After every completed referral, we follow up with the homeowner to confirm the job was completed as quoted, inspections were handled properly, and the Certificate of Completion was delivered. Negative feedback from a completed job triggers a network review. Repeated issues mean removal.
Even within a vetted network, you should ask the right questions before signing a contract. These five questions separate the best installers from the adequate ones — and separate the adequate ones from the ones you should walk away from.
The $18,950 line that never appears on a quote
A real worked example: 3-bedroom bungalow, conventional bed. Tank supplied and set, pipe, stone, fabric, one day of machine and labour, permit allowance — $13,049 with HST. The same job quoted at $32,000. The gap is design fees, markup, and labour you may not need to buy.
Two minutes on the free checker shows the numbers your own lot generates — daily flow, tank size, risk level — before anyone quotes you.
What a Good Septic Quote Should Include
Comparing septic quotes is only useful if you are comparing the same scope. Before accepting or rejecting any quote, verify it includes every one of these items. Missing items are not savings — they are surprises on your final invoice.
| Quote Item | What to Look For | Warning Sign |
|---|---|---|
| Soil evaluation / perc test | Included or already completed with results provided | Not mentioned — likely to be billed as an extra |
| Building permit fee | Itemised separately — $300–$800 depending on municipality | Absent from quote — you may be expected to handle this yourself |
| Tank supply and installation | Tank size specified (minimum 3,600 L), type specified (concrete or fibreglass) | Just “septic tank” with no size or material spec |
| Leaching bed excavation and fill | Cubic metres of fill specified, bed dimensions included | Described vaguely — biggest risk for scope creep charges |
| Distribution system / pump | Explicitly included if Class 2 or 3 system is required | Not mentioned on a lot that clearly needs pressurized distribution |
| Site grading and restoration | Scope clearly described — rough grading vs. topsoil vs. seeding | Not mentioned — you may receive a stripped lot with no restoration |
| Old system removal | Explicitly included — tank pumped, crushed or removed, backfilled | Not mentioned — older tanks left in place can cause future problems |
| Health unit inspections | Contractor confirms they attend all required inspections | No mention of inspections — a serious warning sign |
| Workmanship warranty | Written warranty of 1–2 years on workmanship | Verbal only or no warranty mentioned |
A quote that is 25% or more below all the others almost always means scope has been removed, not efficiency gained. The most common exclusions are: soil evaluation, permit fees, site restoration, old system removal, and proper fill specification. A $16,000 quote that excludes four of those items often ends up costing more than a $26,000 quote that included everything. Always ask for a full itemised breakdown before comparing any numbers.
What Happens If Your Situation Is Complex
An installer referral is the right first step for most straightforward replacement situations. But some situations need a different approach before installers are contacted.
- Failed perc test or Health Unit refusal: Our $1,500 Navigation Package reviews your lot and identifies viable options before you spend time on quotes that may not address the real problem.
- Active system failure with sewage surfacing: Select “Emergency” in the timeline field and we will prioritise your submission immediately — same day wherever possible.
- Planning a bedroom addition or construction project: Consider our Bundle and Save service — coordinating your septic upgrade with construction excavation can save $8,000–$15,000 in mobilization costs in our service area.
- Buying land and need a pre-purchase septic assessment: Our $2,000 Site Assessment Package covers soil evaluation, test holes, and a permit-ready system design — everything you need before committing to a purchase in our service area.
Fill out the form above and describe your situation honestly. We will review it and tell you which service is the right first step — installer referral, Navigation Package, Site Assessment, or Bundle — before routing your inquiry anywhere. We would rather give you the right advice than a fast referral that does not solve your problem.

Questions, answered straight
The Five Questions That Matter
Any hesitation or unwillingness is an immediate red flag. The certificate is public and verifiable at ontario.ca/collegoftrades. A legitimate installer hands you the number without a second thought.
A reputable installer pulls the permit themselves, coordinates all Health Unit inspections, and delivers the Certificate of Completion. If they ask you to get the permit, ask why — and listen carefully to the answer.
Ask for references from the past 12 months on similar soil types and system classes to yours. Call every one of them. Ask specifically whether the job came in on budget and whether the inspector signed off without issues.
A written, itemised quote is non-negotiable. It lets you compare scopes across contractors and immediately reveals when one is excluding items the others included. Never accept an all-in number with no breakdown.
Subcontracting is not inherently a problem, but you need to know who is physically doing the work and confirm they are also licensed and insured. The person on site needs credentials, not just the company you contracted with.
