How to Read a Septic Quote (and Compare Three)

To compare septic quotes, make sure each one prices the same job, then check what is included line by line. A good quote names the tank size, says whether finding the lids, disposal and the filter are included, states whether a permit is needed and who pays for it, and gives the company's Florida DEP registration and warranty. The lowest number is only the best deal if it covers the same work.

This guide walks through each line, gives the questions to ask for each type of job, and lists the red flags to watch for. When you have your quotes, the septic quote comparison tool lines them up side by side in your browser.

Start with the same job

This Old House suggests contacting at least 3 companies and comparing their services as well as their prices. Quotes are only comparable if they describe the same work. Before you look at prices, check that each company is quoting the same service (a pump-out, an inspection, a repair or a drain field job), for the same tank, at the same address. If one company found a problem the others did not, ask the others to look at it too.

Get each quote in writing. This Old House advises getting terms, warranties and emergency policies in writing so you can review everything first. A phone price is a starting point, not a quote.

What a good septic quote lists

Line	Why it matters
Tank size (gallons)	This Old House says tank size drives the base cost of pumping. National guides put a 750-gallon tank at $175–$300 and a 1,500-gallon tank at $345–$600. Ask what happens to the price if the tank turns out larger.
Finding and uncovering the lids	Buried lids add about $50–$200. If the quote leaves this out, the bill can grow on the day. Risers cost about $100–$400 once and save digging next time.
Septage disposal	The company hauls the septage to an approved disposal site. This Old House lists disposal fees among the factors in the price. Ask whether disposal is in the price or billed separately.
Effluent filter	If the tank has an effluent filter, cleaning it adds about $100–$200 when it is not included. This Old House says many companies include it with pumping.
Written report	Ask for the tank size and the sludge and scum levels on the receipt or report, so you have a record for next time.
Permit	Florida's septic rule does not count routine pumping as a repair, so it does not need a repair permit. Repairs usually do, and replacements and new systems do. The quote should say who applies and whether the fee is included. Seminole County's health department, for example, lists $350 for a repair permit (FY 2025-2026).
DEP registration	The registration number of the contractor who qualifies the company (SR or SM) and, for a company set up as a corporation, LLC or partnership, the business's SA number.
Warranty	What it covers (parts, labor, the drain field), for how long, and who honors it.
Emergency and after-hours rate	This Old House says weekend or after-hours pumping typically runs 50–100% above standard rates. If the job is not urgent, booking ahead avoids that.
Insurance	This Old House suggests verifying the company's liability and workers' compensation insurance. Ask for a current certificate of insurance.
Price and timing	The total, the payment schedule, and the expected start and finish dates.

Questions to ask for each type of job

Put the same questions to every company, and write down the answers next to each quote.

Septic tank pumping

Does the price include finding and uncovering the lids?
Is septage disposal included, or billed separately?
Will you check the baffles and clean the filter, and note the sludge and scum levels?
Can you install risers so the next pump-out needs no digging?
What is your charge for emergency or weekend service?

Septic repair

What exactly failed, and can you show me?
Does this repair need a permit, and is the fee in your price?
Are you registered as a septic tank contractor with Florida DEP?
What warranty comes with the repair?

Drain field repair or replacement

Why did the drain field fail, and will the fix address the cause?
Can part of the field be repaired, or does it need replacing?
Does my lot need a raised (mound) drain field?
Does the permit require a nitrogen-reducing upgrade where I live?

New or replacement system

What type of system does my lot need, and why?
Is my lot in a springs or nutrient protection area that requires a nitrogen-reducing system?
What do the permit and design fees come to, and are they in the price?
How long does permit approval usually take?
What warranty covers the tank, the drain field and any pumps?

Septic inspection

Will you pump the tank as part of the inspection?
Will you check the drain field, or only the tank?
What will the written report include?
How soon will I get the report before closing?

Aerobic (ATU) service

How many visits a year does the contract include?
What repairs and parts are covered?
Are you a permitted ATU maintenance entity?
Will you remind me when the operating permit is due?

Check the license behind the quote

In Florida, septic tank contractors are registered by the Florida Department of Environmental Protection (DEP). Individual registrations start with SR (registered) or SM (master) followed by 7 digits, and they expire every September 30. A septic business organized as a corporation, LLC, partnership or association also holds its own authorization, listed with an SA (or SE) number. A contractor working under his or her own given name does not need a business authorization (s. 489.555, F.S.).

Licensed plumbing contractors are licensed by the Florida Department of Business and Professional Regulation (DBPR), not DEP. Under s. 489.105(3)(m), F.S., a plumbing contractor may install, maintain and repair septic tanks "without obtaining an additional local regulatory license, certificate, or registration." So if a quote comes from a plumbing company, check its license on the DBPR license search instead.

You can check septic registrations on DEP's individual search and business search. Our contractor verification worksheet explains what each result means, and the registration checker tests the number format before you search.

How to compare three quotes

Write them in one table. One column per company, one row for each line in the table above. The comparison tool does this for you. Your answers stay in your browser; we only record that the tool was used.
Mark the gaps. Any line a quote does not mention is a question to ask, not a "no".
Add back the extras. If one quote includes lid digging and disposal and another does not, add the published ranges for those extras to the cheaper quote before you compare.
Compare the scope for repairs. For a repair or drain field job, check that each company found the same cause. A cheaper quote that fixes a different problem is not the same job.
Check the registration and permit lines last. A quote without a registration number, or a repair quote with no word on the permit, needs an answer before you sign.

Red flags

The company will not give you a DEP registration number, or the number does not match its name.
The contractor offers to do a repair or replacement "without the hassle" of a permit.
You are told a septic inspection is required by law before you can sell your home. Florida law bars any government from requiring a septic inspection when a home is sold (s. 381.0065(4)(x)). A buyer, a lender or the sales contract can still call for one.
You are pushed to approve a large repair on the spot, without a written quote.
The business name on the truck, the quote and the DEP record are all different.

Also be careful with a quote that says an additive will fix the problem. The EPA says additives are unnecessary for a septic system to work, and pumping is what removes sludge and scum.

Frequently asked questions

How many septic quotes should I get?

This Old House suggests at least 3. For an emergency backup you may not have time, but for a planned repair or replacement, 2 or 3 written quotes show you the normal price where you live.

Should I pick the cheapest quote?

Only if it covers the same work. Check the lid digging, disposal, filter, permit and warranty lines first, because a low price can grow once those are added.

Does a pumping quote need to include a permit?

Usually not. Florida's septic rule (Rule 62-6.002) does not count routine pumping as a repair, so it does not need a repair permit. Local rules can differ, so ask your county permit office. Repairs usually do need a permit.

Can a plumber do my septic work?

Under s. 489.105(3)(m), F.S., a licensed plumbing contractor may install, maintain and repair septic tanks without an additional local license, certificate or registration. Check the plumbing license on DBPR's search, or a septic contractor's registration on DEP's. If you are unsure, ask DEP or DBPR.
