What Len The Plumber does
Len The Plumber Heating & Air is a residential plumbing, HVAC, drain and sewer, well, water-treatment, and indoor-air-quality services contractor serving homeowners across the Mid-Atlantic United States. Founded circa 1994 in the Baltimore, Maryland area, the company operates from six regional offices (Halethorpe, Silver Spring, Alexandria, Boothwyn, Horsham, Cherry Hill) covering Maryland, Washington D.C., Northern Virginia, Pennsylvania, Delaware, and New Jersey, with a field force of 120+ licensed and certified technicians handling approximately 60,000 service events per year. Service capabilities include general plumbing (water heaters, sump pumps, gas and water lines), trenchless sewer line replacement using pipe-bursting methods, video pipe inspection, HVAC repair and replacement (furnaces, boilers, heat pumps, ductless systems), well-pump and well-water services, whole-house water filtration, and air-quality products. Differentiation is anchored on same-day service seven days a week, 24/7 emergency coverage, no overtime or evening charges, upfront pricing, fully stocked trucks for first-visit resolution, and a 100% satisfaction guarantee.
The company operates a direct-to-consumer go-to-market combining 24/7 phone scheduling (800-950-4619), online booking, and promotional offers ($80 off plumbing, $99 off drain cleaning, $49 HVAC tune-up). Revenue is overwhelmingly transactional and quote-based, augmented by a recurring Whole Home Service Plan (three annual inspections across heating, AC, and plumbing, 15% repair discount, priority scheduling). Pricing is not publicly disclosed and no revenue figure has been disclosed in the available sources.
The business is currently owned by Thompson Street Capital Partners, which acquired Len The Plumber in 2021 with unitranche financing from Audax Private Debt. Under PE ownership the platform has executed seven add-on acquisitions between April 2021 and May 2023 — Larry & Sons, Neffsville Plumbing Heating & Cooling, Service Today, Russo Bros & Co, Canady's Heating Air & Plumbing, Acree, and American Air & Heat — extending the footprint and adding adjacent verticals such as residential electrical and indoor air quality.
