What acquirers look at

Recurring maintenance contracts, emergency pricing power and licensed-technician scarcity make the mechanical trades the most consolidated category in small business. Owner age skews high and private equity has been rolling them up since 2019. Plumbing is frequently acquired as a bolt-on to an existing HVAC platform to share dispatch and trucks.
