What moves the multiple
Value drivers in water treatment
Home Services businesses sit within a broad multiple band. These are the specific factors that determine where you land inside it.
Water Treatment-specific
Water-treatment operators with recurring salt-and-service subscription revenue (softener maintenance, RO filter replacements) command premium — the subscription flywheel is what PE and strategic bidders pay up for.
Recurring maintenance agreements that transfer with the sale
Multi-truck fleet with documented dispatch and CRM workflows
Licensed and retained technician bench (usually the #1 diligence question)
Commercial contract mix — even 20% commercial materially lifts multiples
Clean trailing-12-month P&L in QuickBooks or ServiceTitan

Diligence risks
What buyers scrutinize
Every category has structural risks that buyers double-click on. Preparing responses in advance keeps them out of the purchase-price adjustment column.
Water Treatment-specific risk
Water-treatment sales depend on high-value in-home consultations and can face regulatory scrutiny around health claims; buyers will scrutinize your sales-compliance history.
Skilled-technician labor shortage caps organic growth
Seasonal cash-flow swings (buyer wants stable working capital)
Owner-operator dependency — customers loyal to the owner, not the brand
Local licensing and permitting friction on ownership transfer
Active buyers
Who buys water treatment businesses
Buyer archetype depends on scale. Sub-$1M SDE draws individuals and search funds. $1–3M SDE opens platform and strategic interest. $3M+ EBITDA is full LMM buyer territory.
Recent acquirer activity
Culligan International (backed by Advent International + BDT & MSD Partners) has been the aggressive strategic acquirer of regional water-treatment operators.
PE-backed roll-up
PE PlatformPlatform sponsors like Wrench Group, Aspen Grove, and Groundworks actively bid on operators above $1.5M SDE. Pay 10-20% premium multiples in exchange for tighter diligence and transition covenants.
Franchise consolidator
FranchiseOne Hour Heating & Air, Aire Serv, Benjamin Franklin Plumbing, and Mr. Rooter systems will convert independents when the culture and geography fit.
Individual / search-fund buyer
IndividualSBA-financed individual buyers dominate the $500K-$1.5M SDE band. Faster closes, more forgiving diligence, tighter caps.
Playbook
Exit playbook — home services
The single largest driver of purchase-price outcome is preparation depth. These are the levers that move the needle in home services exits.
- 1
Install a General Manager 12-18 months before going to market
12-18 months pre-saleBuyers pay a premium for a business that runs without the owner. Promote from within or hire — the transferability signal is worth 0.5-1x on the multiple.
- 2
Convert one-off customers to recurring service agreements
6-12 months pre-saleEven a 10% agreement penetration meaningfully changes buyer perception of transferable revenue and post-close retention risk.
- 3
Move books from cash to CPA-reviewed accrual
12-24 months pre-saleThis is the single highest-return prep move for most operators. Reviewed statements remove a common diligence discount and unlock PE bidder participation.
- 4
Document your operating procedures — even roughly
3-6 months pre-saleA shared SOP folder with dispatch, install, callback, and customer complaint playbooks materially de-risks diligence.
- 5
Interview at least 2-3 M&A advisors before signing
3-6 months pre-saleThe right advisor for a $1M SDE HVAC business is not the same as for a $5M SDE regional operator. Vet track record in the specific segment.
