How to Switch Aerobic Septic Maintenance Companies Without a Lapse

Can you switch aerobic septic maintenance companies in Texas?

Yes. Texas rules expect owners to change providers now and then, and 30 TAC 285.7 spells out what happens when the owner ends a contract. What you can't do is go without one. Kaufman County's OSSF order says any system using aerobic treatment shall have a maintenance contract, and all maintenance has to be done by a TCEQ-licensed maintenance provider.^source

That second part matters if you've read that Texas lets homeowners maintain their own aerobic systems after the initial two-year service policy. The state rule does allow that. Kaufman County's order doesn't, so in this county a switch always means one licensed provider to another.^source

The legal side is short. The practical side is where people get burned: a gap between contracts, records that stay with the old company, and a county file that still shows the old provider. The rest of this page is about avoiding those three.

The deadlines that control a switch

Five clocks run when you change providers. Two belong to the old provider, one to the new provider, and two to you. If every one of them is met, the county's record never shows a gap.

When is the best time to switch providers?

The cleanest time to switch is at renewal, with the new contract starting the day after the old one ends. You avoid early-cancellation terms, nobody gets paid twice, and the handoff lines up with the 30-days-before-expiration filing rule you already have to meet.

Here's a worked timeline for a contract that expires March 31. Count backward from the expiration date, not forward from the day you got annoyed.

Switching mid-contract works too. Give the old provider written notice at least 30 days ahead, set the new contract's start date to the old contract's last day of service, and read your current contract for what happens to fees you've already paid. Texas rules say nothing about refunds. Your contract does, or it's silent, which usually means you won't see one.

How to switch aerobic maintenance companies in 7 steps

This is the order that keeps the county file clean. It takes about an hour of your time spread over a few weeks.

• Step 1. Read your current contract. Find the expiration date, any auto-renewal clause, the cancellation notice period, and what happens to prepaid fees.
• Step 2. Gather your paperwork: OSSF permit number, system brand and model (on the control panel or a lid), the last three inspection reports, and any repair invoices. If you're missing reports, ask the old provider now, while the relationship is still polite.^source
• Step 3. Get quotes from two or three licensed providers who serve your area. Our aerobic septic maintenance page can connect you with licensed providers working in Kaufman County.^source
• Step 4. Sign the new contract with a start date that begins on or before the old contract's last day. Get a copy with the provider's signature.
• Step 5. Send the old provider a short written notice (email is fine, and keep it) with your address, permit number, and the date service should end. Ask for a copy of their termination paperwork and your remaining reports.^source
• Step 6. Ask the new provider to email you proof that they filed the signed contract with Development Services. Ask whether they pay the county's $25 yearly renewal fee or whether you do.
• Step 7. Put the new contract's expiration date in your calendar with a reminder 60 days ahead, so the next renewal reaches the county well before the 30-day mark.

What records to get from the old provider

Take your history with you. The county has the reports your old provider filed, but getting copies back from a government office is slower than asking for them on your way out. Your new provider will do a better first visit if they can see what the last one found.

Your old tag doesn't transfer. Under 30 TAC 285.7(e)(2), each provider puts a weather resistant tag on the motor cover, control panel, or breaker box at the start of each contract, showing their name, phone number, and the contract start date. Expect the new provider to put up their own, and snap a photo of the old one first.

How to choose the new maintenance provider

Start with the license, then the contract, then the price. A cheaper contract from someone who isn't licensed, or whose contract leaves out required terms, isn't a bargain. Under 30 TAC 285.7(b), maintenance has to be done by a licensed maintenance provider or by a registered maintenance technician working for one, and the licensed provider has to sign every report.^source

Two places to check. TCEQ's licensing search shows whether a person's maintenance provider license is current. Kaufman County Development Services also posts a list of installers and maintenance providers (the version we checked was dated February 2026). The county is clear that the list is informational, not an endorsement, and that you don't have to use anyone on it, as long as the person you hire holds a current state license.^source

Don't let brand loyalty scare you off. Under 285.7(f), the manufacturer of an aerobic system has to make replacement parts available to maintenance providers, so an independent provider can service your unit. Ask how quickly they can get parts for your brand, since a week without an aerator is a week of poor treatment.

For fair pricing and what a contract should include, see our aerobic maintenance contract pricing guide. The questions below are the ones that matter most when you're leaving someone over service.^source

• Who is the licensed provider named on my contract, and what's the license number?^source
• What's your written response time for an alarm or complaint call? The rule requires the contract to state one.
• Who maintains the chlorinator, and are tablets included? The contract has to say who's responsible for disinfection.
• Will you email me every inspection report? You're owed a copy within 14 days of each test.
• Do you file the signed contract with Development Services, and will you send me confirmation?
• What's your price list for common parts and service calls outside the three routine visits?

What the first visit with a new provider should look like

Ask for the first visit to be a full baseline inspection, not a quick look. A new provider is signing reports on a system they've never seen, so a careful first visit protects them as much as you.

Expect findings. A provider who's hungry for your business may be slow to point out problems, and one who wants to justify the switch may find too many. Ask for photos and a written reason for any repair over a couple hundred dollars. Repairs are the owner's responsibility under Texas rules unless your contract says otherwise, so this is your money.

Early termination, auto-renewal, and prepaid fees

Texas rules set the notice and filing deadlines. They don't set cancellation fees, refunds, or auto-renewal terms. Those come from your contract, and they vary a lot from company to company.

Look for three things before you send notice. First, an auto-renewal clause that requires notice some number of days before the renewal date; miss it and you may owe another year. Second, whether the annual fee was paid up front and whether any part of it comes back. Third, whether a discounted first year came with a promise to stay.

If the contract is silent, put your request in writing and ask for a prorated refund. You may not get it, and that's fine. What you can't skip is the new contract. We can't tell you how any particular provider handles this, so get their answer in writing.

Switching providers when you buy a house

Buying a home is the most common time to change providers, and the most common time for a lapse. The seller's contract is usually in the seller's name, and nobody tells the county that a new owner exists.

If the system is still inside its initial two-year service policy, that policy carries over to you under 30 TAC 285.7(d)(4)(A). Get a copy and note the end date. If the system is older, sign a contract in your own name at or soon after closing, even if you plan to shop around later. You can switch again at the first renewal.

Ask for the seller's recent reports during your option period. Our checklist for buying a home on septic in Kaufman County covers what else to request.

Mistakes that turn a switch into a lapse

Almost every lapse we hear about during a switch comes from one of these. None of them are hard to avoid once you know about them.

• Canceling the old contract first and shopping second. The county's file can show no coverage while you collect quotes.
• Assuming the new provider filed with the county. Ask for confirmation every time.
• Letting the new start date float until the provider can schedule the first visit. The contract date and the first visit date are different things.
• Missing the auto-renewal window and ending up with two contracts, or arguing about one.
• Forgetting the 30-days-before-expiration rule when switching at renewal. Signing on the last day of the old contract is too late for that rule.
• Thinking you can maintain it yourself for a few months in between. Kaufman County's order doesn't allow homeowner maintenance of aerobic systems.

If your provider is dropping you instead

If the old company is the one ending things, the same rule applies in reverse. The provider has to give you, the county, and the manufacturer written notice at least 30 days before service stops, and you then have no more than 30 days after termination to file a new signed contract.^source

Don't wait for the 30 days to run. Start calling as soon as the notice arrives. If you never got a notice and just stopped seeing visits, our guide to a lapsed aerobic maintenance contract covers how to get back in good standing.^source
