Non-Compete Agreement When Selling a Business: Terms, Duration & Risks

Key Takeaways

• A non-compete in a business sale stops the seller from competing against the buyer within a defined territory and timeframe after closing, protecting the goodwill the buyer paid for.
• Most sale non-competes cover restricted activity, geographic area, duration, and remedies, and Texas law requires each limit to be reasonable for the goodwill being protected.
• Texas sets no fixed maximum duration, and sellers who stay on for 6 to 12 months after closing can remain bound by the clause once that transition ends.
• Overbroad terms can block post-sale work and lead to costly disputes, and Texas courts reform unreasonable clauses into narrower versions instead of voiding them.
• At Core Growth Group, we walk Texas HVAC and plumbing sellers through transition and non-compete expectations before signing, and we treat that review as part of preparing your business for sale under our Grow, Prepare, Exit framework. 

Signing a Non-Compete as a Texas HVAC or Plumbing Seller

A non-compete agreement in a business sale limits what work the seller can do, where they can do it, and for how long after closing, and Texas accepts any length that stays reasonable for the goodwill the buyer purchased. 

The risks arise when those limits extend beyond what the deal justifies, leaving the seller locked out of their own trade or facing an expensive enforcement fight over terms they never questioned at signing.

If you have signed an employment non-compete before, expect a sale non-compete to be treated differently. Texas courts generally give sale clauses more room, for reasons covered below.

What Is a Non-Compete in a Business Sale?

A non-compete in a business sale is a contract clause that stops the seller from competing against the buyer in the same market for a set period after closing. Buyers typically ask for it to protect the goodwill, customer relationships, employees, and trade relationships they paid for, so they negotiate it alongside price and transition terms as part of the deal structure for an HVAC or plumbing sale.

Under Texas Business and Commerce Code Section 15.50, the clause is enforceable only when it is ancillary to or part of an otherwise enforceable agreement. Its limits on time, geographic area, and scope of activity must also be reasonable and no greater than what the buyer needs to protect its goodwill or other business interest.

Terms Sellers Should Expect in a Non-Compete

Restricted Activity

Restricted activity spells out what the seller can’t do after the sale; in HVAC and plumbing deals, this usually means starting, owning, managing, or materially supporting a competing company within the covered territory. The exact wording deserves a slow read, because a few words can decide how much of the trade stays open to the seller.

A clause banning “any involvement in HVAC or plumbing services” could keep the seller out of unrelated roles across the industry. A clause banning “owning or operating a competing HVAC or plumbing company” covers only direct competition, leaving far more room to work once the transition ends.

Geographic Area

Geographic area draws the restriction’s boundary, and buyers often tie it to the acquired company’s actual service area rather than an arbitrary radius. A buyer of a plumbing company serving Dallas-Fort Worth would usually have a harder time justifying a restriction that reaches Houston, since that market was never part of the goodwill changing hands. 

Duration

Duration sets how long the restriction runs after closing, and its real effect depends on the activity and territory limits it sits beside. A long term attached to a narrow ban on running a competing company leaves the seller far freer than the same term attached to a ban on any work in the trade.

Remedies & Reformation

Remedies are the tools a buyer can use against a seller who breaches the agreement, and they can include injunctions, damages, and fee shifting when the agreement provides for it. For the seller, that means a breach can bring genuine financial and legal consequences.

Reformation under Section 15.51 applies when a covenant is tied to an otherwise enforceable agreement but sets unreasonable time, geographic, or activity limits. The court then reforms the covenant as needed to make it reasonable and enforceable, so an overbroad clause tends to survive in a trimmed-down form. 

Sellers come out ahead by negotiating specific terms at the table, since waiting for a judge to fix the language later costs time, money, and control over the result.

How Long Can a Non-Compete Last When Selling a Business?

There’s no fixed cap on how long a non-compete can last when selling a business in Texas. The law doesn’t hand sellers a magic number like two years or five years that’s automatically safe. Instead, courts look at whether the length matches the actual goodwill and business interest the buyer is protecting, which means duration gets evaluated case by case rather than against a universal standard.

Texas Reasonableness Standard

Texas courts weigh time, geography, and scope of activity together, treating them as one package. A longer term can hold up when paired with a narrow, clearly defined territory, while the same term may draw a challenge when stacked with a sprawling multi-city restriction.

That combined test explains why non-compete language lifted from a template seldom suits a particular HVAC or plumbing deal. A company running four crews in one metro has little in common with one running ten crews across three cities, and a term that fits the first may overreach for the second.

Sale Context vs Employment Context

Courts treat a non-compete tied to a business sale differently from one tied to a job because the seller received payment for the company’s goodwill instead of wages for labor. That payment frames the restriction as protection for a legitimate business interest the buyer now owns.

Sellers who carry assumptions over from an old employment non-compete can misjudge what a sale agreement allows. The price paid at closing, the transfer of customer relationships, and the ongoing transition period all shape what a buyer’s attorney or a court considers reasonable after a sale.

What Are the Risks of Signing a Non-Compete?

Overbroad Restrictions

An overbroad restriction covers more territory, a longer term, or a wider range of work than the buyer actually acquired. This is a frequent sticking point in sale negotiations, since buyers often draft the first version with maximum protection in mind and expect the seller to push back.

Court reformation offers a safety net, but relying on it can turn a negotiation issue into a slow, costly dispute. Challenging overbroad language before signing takes less time and money than asking a judge to narrow it after the relationship has broken down.

Post-Sale Work Limits

Post-sale work limits decide where a seller can earn a living once the transition period ends. Sellers often stay involved for 6 to 12 months after closing and are paid through that window, yet the non-compete can keep running long after their last day. Check with an attorney whether the clock starts at closing or at the end of the transition role, since that one detail can add a year or more to the restriction. 

A seller who planned to consult, manage, or launch a new venture in the trade after the transition may find the clause still blocks them for years. Reading the activity and duration terms side by side before signing shows exactly when that freedom comes back.

Legal Cost & Enforcement Risk

Enforcement disputes bring legal cost, uncertainty, and delay to both sides of the deal. With injunctions, damages, and fee-shifting on the table when the agreement allows them, a single breach claim can become a long, expensive legal fight.

Sellers cover their own legal representation, which is one of the closing costs sellers usually carry in a service business sale. Because each side pays its own attorney, a poorly negotiated clause can leave both the seller and the buyer with legal bills if a dispute follows.

Plan the Transition With Core Growth Group Before You Sign

A non-compete determines what you can and can’t do for years after closing. Reasonable terms protect the buyer without keeping you tied up long after the transition ends. Overbroad terms cost far less to fix during negotiation than in court, so work with an attorney to push for clear limits in the weeks before signing. 

At Core Growth Group, we buy HVAC and plumbing companies across Texas. Our founder, Clint, runs his own service business and has acquired a service business himself, so he understands what sellers face during a transition. We sit down with owners to walk through transition expectations, deal structure, and what our non-compete typically covers before any agreement is signed. If you want that clarity early, talk through your sale and transition period with Core Growth Group.

Frequently Asked Questions (FAQs)

Are non-competes still enforceable after the FTC rule?

Non-competes remain enforceable under state law because the FTC Non-Compete Clause Rule is not in effect. The FTC filed to accede to vacatur on September 5, 2025, ending its related appeals, and a Federal Register action removed the rule from federal regulations effective February 12, 2026, which leaves Texas’s reasonableness standard in charge.

What makes a Texas non-compete reasonable?

A Texas non-compete is reasonable when its time, geography, and activity limits protect the buyer’s goodwill without imposing more restraint than necessary. The Texas Workforce Commission’s guidance confirms that Texas law requires reasonable limits on all three: time, geographic area, and scope of activity. 

Can a court rewrite an overbroad non-compete?

A Texas court can rewrite an overbroad non-compete by reforming it to make it reasonable and enforceable, provided it is tied to an otherwise enforceable agreement. The narrowed restriction then stays in force, so an aggressive clause seldom disappears entirely after a challenge.

Should sellers get legal advice before signing a non-compete?

Sellers should have their own attorney review any non-compete before signing because enforceability depends on state law, the contract wording, the deal’s facts, and how a court reviews it. This article does not provide legal advice, and a qualified attorney can assess the specific covenant you are being asked to sign.

How does Core Growth Group handle seller transition expectations?

At Core Growth Group, we handle transition expectations as a direct, operator-led buyer. Our founder, Clint, runs his own service business, so we can show you how the paid transition role and the non-compete work together well before anything is signed.
