## The honest read

781 Plumbing & HVAC is a small Malden company covering general plumbing, drain cleaning, gas lines, boilers, furnaces and water heaters, with someone reachable around the clock.

Speed is what customers describe. A homeowner whose water heater ruptured overnight in September 2026 had a technician at the door by 8 a.m. who pulled the old tank and put a new one in. A plumbing emergency in August brought someone to the house within 20 minutes. Another customer called on a Friday evening, Alex arrived Saturday morning, and Stanley followed up afterwards to check it had gone well. When an air conditioning system died during the Fourth of July heatwave in 2026, Stanley and Demitri were the ones who revived it.

The work runs across both trades. A customer of five years has had a completely new heating system put in at home, including a conversion off oil, and uses the company at their businesses as well. A landlord has had Stan upgrade heating systems, replace hot water heaters and diagnose and fix gas leaks across rental properties. In July 2026 a mini split went in cleanly and was tested before the team left; in June a customer had a pipe and spigot fixed and a condenser sorted out in a single visit.

Several people describe being talked out of spending money. In December 2022 a caller was advised over the phone instead of being sold a visit, and in November that year another said they felt no push toward a bigger job. In November 2023 a landlord whose tenant's boiler failed on a Thursday night had already been quoted $23,000 for a replacement by a competitor doing annual maintenance before calling Stanley. In July 2026 the owner came out the same day to evaluate a mini split heating and cooling system free of charge.

One thing to settle before booking. The company publishes corporate plumbing licence #4009 on its own website, and the state registry records licence 4009-PL-C, held by 781 Plumbing and Heating, Corp, as expired. Ask for the current licence status in writing — it is the kind of thing to have in hand before permitted work starts.

For a burst water heater, a dead condenser in a heatwave or a boiler that quits on a weeknight anywhere around Malden and the northern suburbs, this is a strong call for the response time alone; ask about the licence status and who pulls the permit before the work is scheduled.

**Strengths:**
- 20-minute emergency response — an August 2026 plumbing call answered that fast
- Same-day water heaters — a ruptured tank replaced by 8 a.m.
- Weekend cover — a Friday evening call answered Saturday morning
- Heatwave AC rescues — a July 2026 system revived over the holiday
- No upselling — 2022 callers were advised over the phone instead
- Repeat landlords — rental heating, water heaters and gas leaks handled

**Concerns:**
- Expired registration — the state lists plumbing licence 4009-PL-C expired
- Site licence claim — #4009 appears on its own website unverified

**Where sources disagree:**
- The company publishes corporate plumbing licence #4009 on its own website, while the state registry records licence 4009-PL-C under 781 Plumbing and Heating, Corp as expired.
