You get a plumber who shows up when promised and fixes it right the first time. No more wondering if that leak will get worse or if your water heater will make it through winter.
Our licensed team handles everything from emergency burst pipes to routine water heater maintenance. You’ll have hot water when you need it, drains that actually drain, and the peace of mind that comes from working with plumbers who’ve been serving Marshfield families for over three decades.
When plumbing problems hit, you don’t need more stress. You need someone who understands that your time matters, your home matters, and getting it fixed right matters more than getting it fixed cheap.
Dempsey Energy started as a family-run company helping local homeowners, and that’s exactly what we still are. We’ve grown to serve thousands of customers across the South Shore, but our approach hasn’t changed.
Every plumber on our team is licensed, certified, and trained on current code. We know Marshfield’s unique challenges—from saltwater corrosion affecting coastal homes to the older plumbing systems in many of our historic neighborhoods.
You’re not just another service call to us. We’re the plumbing company your neighbors recommend because we show up when we say we will, explain what’s wrong in plain English, and stand behind our work.
First, we listen. You tell us what’s happening, and we ask the right questions to understand the problem. No rushing, no assumptions.
Next, we assess everything. Our plumber checks water pressure, examines drain flow, and looks for hidden issues that could cause bigger problems later. You get a clear explanation of what we find.
Then we give you options. We explain what needs to be fixed now, what can wait, and what each option costs upfront. No surprises, no pressure—just honest information so you can make the right decision for your home and budget.
Finally, we fix it right. We bring the right tools and parts to handle the job completely, not just patch it up. You get work that lasts and a plumber you can call again when you need us.

We handle the full range of plumbing services Marshfield homes require. Emergency repairs when pipes burst or drains back up. Water heater installation and repair for both gas and electric units. Fixture upgrades, garbage disposal installation, and complete bathroom renovations.
Living near the coast means dealing with saltwater’s effects on plumbing systems. We understand how corrosion affects pipes in Marshfield homes and know which materials and solutions work best for our local conditions.
Whether you’re in one of the historic homes near the village center or a newer development closer to the beaches, we’ve worked on similar properties. We know what works, what doesn’t, and how to get your plumbing running properly without unnecessary expense or disruption to your daily routine.
Any situation causing flooding, water loss, or sewer smells needs immediate attention. Burst pipes can cause thousands in water damage within hours, especially in finished basements or near electrical systems.
Sewer backups create health hazards and contamination issues that get worse every minute they’re left untreated. No hot water might seem less urgent, but water heater failures can involve gas leaks or electrical hazards that require professional diagnosis.
If you’re seeing water where it shouldn’t be, smelling sewer gases, or dealing with complete loss of hot water, call us right away. These problems don’t fix themselves, and waiting usually makes them more expensive to repair.
Water heaters typically last 8-12 years, so age is the first indicator. If yours is approaching that range and showing problems, replacement often makes more sense than repeated repairs.
Watch for these warning signs: water that’s not getting hot enough, unusual noises like popping or rumbling, rusty or discolored hot water, or visible leaks around the unit. Any of these suggest internal components are failing.
Higher utility bills without increased usage often mean your water heater is working harder to do the same job. We can test efficiency and help you decide whether repair or replacement gives you better long-term value for your specific situation.
Sudden pressure drops usually point to one of three issues. Your main shutoff valve might not be fully open—this happens after water main work or meter replacements when the valve doesn’t get turned back completely.
A faulty pressure regulator can cause system-wide pressure problems. These devices control water pressure coming into your home, and when they fail, you’ll notice it at every fixture.
Corroded or clogged pipes, especially in older homes, restrict water flow and reduce pressure. This is common in Marshfield’s older neighborhoods where original galvanized pipes are reaching the end of their useful life and need replacement.
Sewer gases entering your home through drains indicate problems with your plumbing’s venting system or trap seals. Every drain has a water trap that should block these gases—when traps dry out or get damaged, you’ll smell it.
Backups happen when debris builds up in pipes or when tree roots invade sewer lines. In Marshfield, older sewer systems and mature trees create the perfect conditions for root intrusion, especially during wet seasons.
Grease, hair, and soap buildup gradually narrow pipes until water can’t flow properly. Once drains start backing up, the problem usually gets worse quickly because debris catches more debris. Professional drain cleaning removes buildup and identifies underlying issues before they become emergencies.
Yes, every job starts with a clear diagnosis and free estimate before any work begins. We explain what we found, what needs to be fixed, and exactly what it will cost.
You’ll know the total price upfront, not after we’re halfway through the job. No surprise charges, no “additional costs we discovered,” and no pressure to approve work on the spot.
We also offer financing options for larger jobs and discounts for veterans, first responders, elderly customers, and maintenance plan members. Our goal is making necessary repairs affordable and predictable, not maximizing what we charge for each service call.
We provide 24/7 emergency service because plumbing problems don’t wait for business hours. Whether it’s 2 PM or 2 AM, our emergency team responds to burst pipes, sewer backups, and major leaks.
Response time depends on your location in Marshfield and current emergency call volume, but we prioritize situations involving flooding, water damage, or health hazards. We’ll give you an accurate timeframe when you call.
Our emergency trucks carry the tools and common parts needed to resolve most problems on the first visit, not just diagnose them. The goal is stopping the immediate problem and getting your plumbing functional again, then scheduling any additional work at your convenience.
