Who Is J J Sullivan Plumbing & Heating?
J J Sullivan Plumbing & Heating is a licensed, fully insured plumbing and HVAC contractor based on Somerville Avenue in Somerville, Massachusetts. Founded over 30 years ago, the company has built its reputation on three pillars: reliability, transparency, and technical excellence.
Unlike national chains that rotate technicians, J J Sullivan employs the same skilled team year-round—many with 15+ years of experience. This consistency means your technician remembers your home’s history, reducing diagnostic time and preventing repeat issues.
According to the U.S. Bureau of Labor Statistics, Massachusetts requires all plumbers and HVAC technicians to hold state-issued licenses—a standard J J Sullivan not only meets but exceeds by maintaining ongoing certifications in gas piping, backflow prevention, and energy-efficient heating systems.
“In older cities like Somerville, where 68% of homes were built before 1970 (U.S. Census Bureau, 2024), outdated plumbing and inefficient heating are common. You need someone who understands vintage systems and modern code compliance.”
— Mark Delaney, Senior Building Inspector, City of Somerville

How to Know If You Need Emergency Plumbing Help
Not every drip requires a midnight call—but some signs mean act now:
✅ Flooding or pooling water near appliances or walls
✅ Sewage backup in sinks, tubs, or toilets
✅ No heat when outdoor temps drop below 40°F
✅ Gas smell (rotten egg odor)—evacuate and call 911 first, then your plumber
✅ Frozen pipes showing bulges or frost
J J Sullivan offers 24/7 emergency service with no after-hours surcharge—a rarity in the Boston metro area. Most calls receive a callback within 15 minutes and on-site arrival within 90 minutes.
Step-by-Step: What Happens During a Heating System Tune-Up?
If you’re scheduling annual maintenance (highly recommended before November), here’s exactly what J J Sullivan’s technicians do:
- Inspect the heat exchanger for cracks (a major CO risk).
- Clean burners and ignition assembly using compressed air and non-corrosive solvents.
- Check thermostat calibration—adjust if off by more than ±2°F.
- Test safety controls (limit switches, flame sensors).
- Measure airflow (ideal: 400 CFM per ton of cooling/heating capacity).
- Lubricate motors (if applicable—many modern units are sealed).
- Provide a digital report with photos, recommendations, and efficiency score.
This 45–60 minute process can extend your system’s life by 5–8 years and prevent 80% of mid-winter breakdowns (ASHRAE Journal, 2023).
Common Plumbing Issues in Somerville Homes (And How J J Sullivan Fixes Them)
Due to Somerville’s aging infrastructure, certain problems recur:
- Galvanized pipe corrosion: Common in pre-1980 homes. J J Sullivan replaces sections with PEX or copper—typically $1,200–$3,500 depending on access.
- Low water pressure: Often caused by mineral buildup. They use hydro-jetting ($175–$300) instead of chemical cleaners that damage pipes.
- Sump pump failure: Critical in flood-prone areas like East Somerville. They install battery backups with WiFi alerts.
- Frozen outdoor spigots: Prevented via frost-proof sillcocks ($225 installed).
Their diagnostic fee ($89) is waived if you proceed with repairs—no bait-and-switch tactics.
