This article is written by a plumbing and septic company, so read it with that in mind. What follows is the set of checks we would want a family member to run — and they work regardless of who you end up hiring.
Confirm licensing and insurance
Tennessee licenses plumbing contractors, and septic system work requires its own qualification. Ask for the license and verify it rather than taking a website badge at face value.
Insurance matters as much. If somebody is injured on your property or something is damaged, an uninsured contractor becomes your problem.
On septic work specifically this is not paperwork nitpicking. Installation, replacement and field repair all require permits and inspection, and unpermitted work has a habit of surfacing at resale — at which point it is your problem, not the person who did it.
Insist on a written estimate before work starts
A verbal "it will be around" is not an estimate. You should have a number, in writing, for a defined scope, before anyone opens anything.
Ask specifically what happens if they open a wall or a tank and find something unexpected. The right answer is that work stops, you are shown the finding, and the additional work is quoted separately before it proceeds.
Ask how they diagnose
This is the question that separates good work from expensive guessing, and almost nobody asks it.
- For a recurring drain problem: will you camera the line, or just cable it again?
- For a septic complaint: will you measure sludge and scum depths, or just pump it?
- For a water heater: will you check the serial number and test the components, or quote a replacement?
- For a suspected leak: will you locate it electronically, or open walls until you find it?
- For a failing drain field: what will you rule out before quoting a rebuild?
Read the reviews properly
Not the star average — the content. Look for reviews that describe what was actually done, mention specific neighbourhoods, and read like a person wrote them.
Read the negative ones too, and read the responses. A company that answers a complaint calmly and specifically is telling you more than one with no complaints at all.
Be wary of a large number of reviews appearing in a short window, and of reviews that praise the company without describing any work.
Red flags worth walking away from
- Pressure to decide immediately on non-emergency work
- A quote for a replacement without any diagnosis of what failed
- Refusal to provide a written estimate
- Large payment up front on a routine job
- Vagueness about licensing, insurance or permits
- Cash-only, no invoice, no paperwork
- On septic: a recommendation to replace the field without opening the tank first
- Anyone who tells you an additive will let you skip pumping
Questions specific to septic
A large share of properties around Ooltewah, Apison, Harrison and the county roads are on private systems, and septic work is where the biggest numbers live.
- Are you licensed for septic work specifically, not just plumbing?
- Will you open the tank and inspect the baffles, or only pump it?
- Will you measure my sludge and scum layers and give me an interval?
- Do you handle the county permit and inspection on repair or installation work?
- Will I get a written record of what you found?
Most plumbing companies in this market refer septic work out, which is not a criticism — but it does mean a slow-drain call that turns out to be a full tank becomes a referral and a wait.
What good looks like
Diagnosis before quoting. A written price before work. Photos of what was found, including the parts that were fine. A plain explanation you can follow. And an honest "you do not need this yet" when that is the truth.
That last one is the strongest signal there is. A company that tells you your tank has two more years in it has just declined an invoice, and that is worth more than any badge on a website.
Frequently asked
Ask for the license number and verify it with the state rather than accepting a badge on a website. Septic work requires its own qualification separate from plumbing, so ask specifically about that if the job involves a tank or a drain field. Also confirm insurance — an uninsured contractor's accident becomes your problem.
For significant planned work — a repipe, a septic installation, a drain field — yes, and compare the scopes rather than just the totals. Quotes that look different often differ on what is included: permits, restoration, disposal, or the system type being proposed. For an emergency, get one competent company there quickly instead.
A quote for an expensive replacement with no diagnosis of what actually failed. On septic that means recommending a new drain field without opening the tank first — there are at least four cheaper causes that produce identical symptoms, and any of them should be ruled out before a rebuild is on the table.
