What SDE Multiple Do Plumbing Businesses Sell For in 2026?

Most plumbing businesses sell for 2.0x-3.5x SDE in 2026 for small owner-operated shops under $1M in SDE, with larger residential service businesses holding $1M+ in EBITDA regularly transacting at 5.0x-7.0x EBITDA when they have recurring maintenance membership programs, 20%+ margins, and a functioning operations team. Residential service plumbers command a meaningful premium over commercial contractors because recurring service call revenue and membership programs create durable cash flow that PE-backed rollup platforms can underwrite. The most active acquirers today are Wrench Group, Apex Service Partners, Sila Services, Redwood Services, and regional home services strategics that are often themselves PE-funded.

Quick Answer

  • Small Shops (Under $1M SDE): 2.0x-3.5x SDE
  • Residential Service ($1M+ EBITDA): 5.0x-7.0x EBITDA
  • Active Buyers: Wrench, Apex, Sila, Redwood Services + regional strategics
  • Membership Premium: 2.0x-3.0x annual recurring revenue above EBITDA multiple

What Drives the Spread Between 2.0x and 7.0x?

Three things separate a 2.5x SDE shop from a 6.5x EBITDA platform add-on. First, size: buyers pay materially more for every incremental dollar of earnings above $500K because the business moves from an owner-operator profile to an add-on opportunity for a PE-backed platform. A $300K-SDE shop competes with other small-business buyers paying 2.0x-3.0x, while a $1.2M-EBITDA operator competes with 10-plus PE-backed strategics paying 5.5x-7.0x. Second, residential versus commercial mix: residential service plumbers with call volume from homeowners have higher margins (typically 18%-25%) and the potential to convert transactional calls into recurring membership revenue. Commercial plumbing contractors with project-based revenue and lower repeat frequency typically trade lower. Third, recurring revenue: platforms like Redwood Services have shown that membership programs can shift revenue mix from 10% recurring to 40%+ in 18-24 months, and every turn of that mix shift adds valuation. Maintenance agreement revenue is often valued separately at 2.0x-3.0x its annual run rate on top of the EBITDA multiple applied to the rest of the business.

What Does a Typical Plumbing Deal Look Like?

A residential plumbing business with $500K of SDE and no recurring membership book generally clears $1.0M-$1.5M, or 2.0x-3.0x SDE. The same business with a membership program covering 25%+ of customers can clear $1.5M-$2.0M as a platform add-on. At the mid-market level, a $2M-EBITDA residential service plumber with strong membership penetration, 22%+ margins, and a regional footprint clears $12M-$16M enterprise value, or 6.0x-8.0x EBITDA. Commercial plumbing contractors working larger project-based revenue typically trade 1.0x-1.5x turns lower for the same earnings because the cash flow is lumpier and customer retention is lower.

The biggest value creation lever I see plumbing owners overlook is the membership book. I had a Charlotte-area residential plumbing operator come to me at $480K SDE convinced he was worth $1.2M. We spent 14 months building a $19/month membership program, got 32% of his customer base enrolled, and the combination of margin expansion and recurring revenue made him a platform add-on candidate rather than a small-business sale. He closed at $2.4M — a full turn of multiple higher because the buyer pool widened.

A residential plumbing business with $500K of SDE and no recurring membership book generally clears $1.0M-$1.5M, or 2.0x-3.0x SDE. The same business with a membership program covering 25%+ of customers can clear $1.5M-$2.0M as a platform add-on because the buyer pool widens to include PE-backed strategics. At the mid-market level, a $2M-EBITDA residential service plumber with strong membership penetration, 22%+ margins, and a regional footprint clears $12M-$16M enterprise value, or 6.0x-8.0x EBITDA. Commercial plumbing contractors working larger project-based revenue typically trade 1.0x-1.5x turns lower for the same earnings because the cash flow is lumpier and customer retention is lower. The best path to valuation expansion for most small plumbing owners is to systematically convert transactional customers into a membership book, which both lifts near-term earnings and widens the eventual buyer pool.
