How do I sell my plumbing business in Texas?
To sell a plumbing business in Texas for full cash at close, separate the company from your personal TSBPE Responsible Master Plumber (RMP) designation (Texas Occupations Code Chapter 1301), document residential service-agreement renewal rates or commercial WIP schedules, and shift daily dispatch and estimating to a non-owner manager before talking to buyers. Owner-reliant plumbing shops trade at 2.5x–3.4x SDE, whereas system-driven Texas plumbing companies with a non-owner RMP and recurring maintenance plans command 3.8x–6.2x Adjusted EBITDA.
Residential service-agreement vs. commercial rough-in plumbing valuation multiples in Texas
Private equity home-service platforms, regional MEP groups, and SBA 7(a) acquisition buyers price Texas plumbing companies based on three operational tests: whether gross margin comes from recurring residential service and drain/water-heater replacement vs. low-margin tract-home rough-in bids, whether a licensedJourneyman/Master bench dispatches without the founder, and whether a non-owner Responsible Master Plumber is already registered with TSBPE.
| Plumbing Contractor Profile | Typical Earnings Base | Texas Valuation Multiple | Typical Deal Structure & Diligence Focus |
|---|---|---|---|
| Owner-Dispatched Residential Service or New-Build Rough-In Shop Founder holds the sole RMP designation, quotes repipes/commercial jobs personally, or relies on 1–3 homebuilders for >40% of revenue. |
$200K–$600K SDE |
2.5x–3.4x SDE | SBA 7(a) buyer with 15%–25% seller note or holdback tied to TSBPE Responsible Master Plumber continuity and builder retention. |
| Mid-Sized Residential Service & Light Commercial Plumbing Contractor 8–20 service trucks, ServiceTitan/Housecall Pro flat-rate pricebook, dedicated dispatcher, non-owner Master Plumber on staff. |
$650K–$1.6M Adjusted EBITDA |
3.8x–4.8x Adjusted EBITDA | 75%–85% cash at close via SBA 7(a) or regional MEP acquirer; 10%–15% seller note; normalizes truck fleet maintenance and technician callback warranty costs. |
| Institutional Residential Service-Agreement or Commercial Mechanical Platform 1,500+ active residential maintenance memberships or bonded commercial medical/industrial backlog, GM + non-owner RMP in place. |
$1.6M–$4.5M+ Adjusted EBITDA |
5.0x–6.2x+ Adjusted EBITDA | PE platform add-on or strategic MEP buyer; 80%–90% cash at close, 10%–20% rollover equity or earnout; full sell-side QoE and NWC peg true-up. |

1. Solve TSBPE Responsible Master Plumber (RMP) continuity before going to market
Under Texas Occupations Code Chapter 1301 (§1301.351 and 22 TAC §367.3), no person or company may advertise or engage in plumbing contracting in Texas without a designated Responsible Master Plumber (RMP) who carries the required certificate of insurance on file with the Texas State Board of Plumbing Examiners. That RMP status belongs to the individual Master Plumber, not the LLC or corporation.
When the selling owner is the sole RMP and wants to walk away at closing, municipal permitting and commercial dispatch freeze the moment the owner removes their license. SBA 7(a) lenders and PE diligence teams will either require you to remain on the certificate of insurance for 6–12 months under a post-close qualifier agreement (fitting inside the SBA SOP 50 10 8 12-month seller transition cap) or withhold 15%–25% of the purchase price in escrow until a replacement RMP is registered with TSBPE.
What to do 6–12 months before sale: Sponsor a senior Journeyman Plumber on your crew who meets the 4-year experience threshold to sit for the TSBPE Master Plumber exam, complete the RMP training requirements, and register them as a non-owner Master Plumber on a written retention bonus agreement.

2. Reconcile flat-rate service deferred revenue, commercial WIP, and fleet recapture
Buyers inspecting a Texas plumbing company focus on three balance-sheet and Quality of Earnings items that routinely reduce net cash at close if left unaddressed:
- Commercial rough-in and tenant-finish WIP over-billings: If you perform commercial plumbing or multi-family rough-in work and bill heavy mobilization or fixture deposits upfront, buyers treat net over-billings (billings in excess of costs and estimated earnings) as a dollar-for-dollar debt-like deduction at close. Review our Contractor WIP & Over/Under-Billing Diligence Guide to normalize job costing before opening a data room.
- Fleet depreciation recapture (IRS Form 8594 & IRC §1245): Service vans, hydro-jetters, camera rigs, and mini-excavators that were fully expensed under Section 179 or bonus depreciation trigger ordinary income recapture (up to
37%) in an asset sale if the buyer writes them up to replacement value. Model your Asset Sale vs. Stock Sale tax allocation before signing an LOI. - ServiceTitan / Housecall Pro pricebook & callback audit: PE and strategic buyers audit average ticket, technician conversion rate, sewer/water-heater financing attachment, and warranty callback rework. Removing personal vehicles, non-working family payroll, and one-time equipment expenses into a clean Quality of Earnings add-back schedule prevents a
3.8x–6.2xmultiple haircut during diligence. - Texas Comptroller Certificate of No Tax Due (Form 86-114): Under
Texas Tax Code §111.020, buyers withhold final purchase funds until the Texas Comptroller confirms all sales and franchise taxes on commercial repair/remodeling vs. residential new-construction jobs are clear.
