Septic and well contractors operate in a regulatory environment that protects both public health and the environment — which means licensing, permitting, and regulatory compliance are non-negotiable quality indicators. A company that operates without proper authorization isn’t just cutting corners; they’re potentially creating public health hazards, environmental violations, and legal liability for the homeowner.
“The first thing I check when a homeowner calls me about a septic problem is: who serviced it last, and were they authorized? Because unauthorized work on a septic system doesn’t just void whatever warranty might exist — it can make the homeowner liable for regulatory violations, and it often makes the underlying problem worse. Authorizations in this trade aren’t paperwork. They’re how we know the work was done safely.”
— Marguerite Fournier, licensed septic system installer and well contractor with 18 years of experience in rural water and wastewater systems in the local area

Red Flags for Septic Service
Unable to provide a septic authorization number. In many regions, septic system service providers and installers must be authorized under the applicable building code. A company that can’t provide their authorization number is potentially unlicensed — which means any work they do on your system may be illegal and uninsured.
Recommending leaching bed replacement without a proper diagnostic. Leaching bed replacement is expensive. Before recommending it, a legitimate contractor performs a thorough assessment — tank pumped and inspected, D-box assessed, bed condition evaluated. A recommendation for full replacement after a brief visual inspection is a red flag.
Proceeding with septic work without a permit. Any significant septic work in many regions — new installation, replacement, or significant alteration — requires a permit from the local health unit. A contractor who proposes to proceed without discussing permits is operating outside the regulatory framework. The homeowner can be held responsible for unauthorized work.
Recommending septic additives or enzymes as a system “fix.” There is no scientific evidence that commercial septic additives improve system performance or can revive a failing leaching bed. Any contractor recommending additives as a primary solution is either uninformed or upselling.
Pumping the tank without inspecting the baffles and effluent filter. A pumping visit that doesn’t include baffle inspection and filter cleaning (where applicable) is delivering partial service. Ask for these inspections as part of every pumping visit.
Red Flags for Well Service
Unable to provide a well contractor licence number. Well drilling, construction, and alteration in many regions requires a licence under the applicable regulation 903. An unlicensed well contractor cannot legally drill or alter a well — and any work they do carries no regulatory oversight.
Recommending water treatment without water test results. Any water treatment recommendation that isn’t based on your specific water test results is a product sale, not a solution. Ask to see the test results before accepting any treatment recommendation.
Not testing the well after any work is done. Any disturbance to a well — pump replacement, casing repair, shock chlorination — should be followed by a bacteriological test before the water is used. A contractor who completes well work and doesn’t arrange follow-up testing hasn’t completed the job.
Using inappropriate grout or no grouting. The annular space between the well casing and the drilled hole must be grouted from near the surface to the bottom of the casing to prevent surface water from contaminating the aquifer. A well drilled without proper grouting may pass a pressure test but allow surface contamination over time.
Recommending shock chlorination as the permanent solution to bacterial contamination. Chlorination disinfects the well and distribution system — it is a temporary measure. If the source of bacterial contamination (a compromised casing, poor grouting, surface water entry) isn’t identified and fixed, the contamination will recur. Shock chlorination alone, without diagnosing and fixing the source, is incomplete.
General Red Flags (Both Septic and Well)
Cash only, no written contract or invoice. A professional septic or well service company provides written documentation of everything — what was found, what was done, what was recommended. Cash-only operators have no accountability.
No liability insurance. Septic and well work involves excavation, heavy equipment, and potential contamination risks. Liability insurance is essential.
Working on a property near a water body without checking setback requirements. Properties near lakes, rivers, and wetlands have specific setback requirements for both septic systems and wells. A contractor who proceeds without checking these is exposing the homeowner to regulatory violations.
