What Mike Diamond does

Mike Diamond Services is a residential home services contractor operating in Southern California since 1976, headquartered at 1900 N Cahuenga Blvd in Los Angeles. The company delivers plumbing, HVAC, and electrical services — including emergency response, drain and sewer cleaning, water heater and tankless water heater installation, leak detection, sewer repair, electrical panel and rewiring work, and AC/heating installation and repair — to homeowners across Los Angeles, Orange, San Bernardino, and Ventura counties. Services are executed by licensed technicians dispatched from fully stocked service vehicles, with 24/7 phone availability (800-446-6453) and online booking; the company maintains seven physical offices (Hollywood, Costa Mesa, Pomona, Anaheim, North Hollywood, Gardena, Inglewood) and runs localized SEO pages for 60+ cities.

The underlying technology is industry-standard trade equipment — hydro-jetting rigs, drain/sewer cameras, leak detection hardware — rather than proprietary software or AI systems. The company's primary differentiator is the "Smell Good Plumber" brand promise: clean, punctual, no-upsell, no-surprise-fee service, protected by a registered service mark and reinforced through Google reviews, a content-heavy blog, social media presence (LinkedIn, Facebook, X, Instagram), and a monthly email newsletter. Mike Diamond does not publish revenue and operates without disclosed institutional capital or acquisition history; legal structure is reported only as a privately held California entity.

Revenue is generated through two streams: (1) on-demand, per-job pricing for one-time plumbing, HVAC, and electrical work (with promotional anchors such as $99 drain cleaning, $49 water audit, free water quality test, and installation discounts), and (2) subscription Protection Plans at $99 covering plumbing, heating, and air conditioning, which provide priority scheduling and discounted repairs. The customer base is exclusively individual residential homeowners in Southern California; no commercial or enterprise accounts are disclosed.
