Our East Dennis Plumbing Services
East Dennis homes depend on plumbing systems that function reliably every day, delivering clean water, removing wastewater, and protecting your property from leaks or flooding.
Cape Cod’s coastal environment creates unique plumbing demands, from salt air that accelerates corrosion to seasonal properties that sit idle for months.
GEM services all major components of your plumbing system, including water heaters, drains, sump pumps, well pumps, and water treatment equipment. Whether you’re facing an urgent leak or planning upgrades for improved performance, our technicians have the experience and tools to handle it right, backed by over 75 years serving East Dennis and surrounding Cape Cod communities.
Emergency Plumbing Services
GEM offers 24/7 emergency plumbing service across East Dennis, so you can count on us day or night to restore your comfort and safety fast.
Burst pipes, overflowing fixtures, and sudden leaks don’t respect schedules, and neither do we. We understand the stress when water floods your basement or drains back up while you’re preparing for guests. A small leak can quickly escalate into major damage, raising repair costs and disrupting your plans. That’s why our local, licensed plumbers arrive equipped to contain the problem, repair it correctly, and protect your home from further harm. From water heater failures to malfunctioning sump pumps and sewer backups, GEM responds with the expertise and care your emergency demands.
Plumbing Installation
Professional plumbing installation prevents leaks, pressure problems, and premature system wear.
GEM takes the guesswork out of the process with clear communication, transparent pricing, and trustworthy recommendations. We install everything from faucets, sinks, and showers to water heaters, garbage disposals, and whole-house repiping. Whether you’re building new, renovating a bathroom, or replacing worn fixtures, we make installation straightforward. Every project meets code, undergoes performance testing, and carries GEM’s commitment to quality workmanship. You get a system that looks great and performs dependably for years.
Plumbing Repair
When plumbing problems disrupt your day, GEM helps East Dennis homeowners restore normal function quickly.
Minor issues like dripping faucets, sluggish drains, or toilets that won’t stop running can escalate into serious headaches. Ignored, they waste water, inflate utility bills, and can damage your home’s structure. Our plumbers handle every type of repair, from stubborn clogs and leaking fixtures to damaged supply lines, sewer backups, and struggling water heaters. We pinpoint the cause, explain it simply, and discuss your options before starting any work.
Plumbing Maintenance
Regular maintenance keeps your plumbing in good condition and helps you avoid unexpected breakdowns.
Preventive care also extends the life of your water heater, pipes, and fixtures, saving money and hassle over time. For seasonal properties, maintenance before closing for winter or opening for summer is especially important. GEM’s experienced plumbers check for hidden leaks, corrosion, pressure irregularities, and early wear that typically goes unnoticed until damage occurs. We clear drains, test water pressure, and confirm every fixture, connection, and valve operates as designed.
Drain Cleaning
GEM’s plumbing pros use advanced tools like camera inspections and hydro jetting to locate and clear blockages safely and effectively.
Clogged drains in East Dennis may seem minor but often indicate deeper problems within your plumbing system. Cape properties accumulate sand and debris that affect drains differently than inland homes. Grease, soap residue, hair, and debris accumulate inside pipes over time, leading to slow drainage, unpleasant odors, and eventually backups that damage floors and walls. We locate the source, clean your drains completely, and restore proper flow throughout your home.
- Hydrojetting: When drain snakes and plungers won’t cut it, high-pressure water cleaning blasts away grease, roots, mineral buildup, and stubborn clogs completely.
Water Treatment
Your East Dennis family deserves clean, safe water from every tap.
Cape Cod water quality varies by location, and many East Dennis homes benefit from treatment systems. GEM helps local families improve water quality with reliable, long-lasting treatment solutions. From whole-house filtration to water softening, we make better water easy to achieve.
- Water Purifier System Installation: When tap water tastes strange, smells off, or appears cloudy, a purification system makes a real difference. GEM installs water filtration systems in East Dennis designed to remove contaminants, chlorine, and sediment. Our team evaluates your water and recommends the right solution, delivering safe drinking water your family can count on.
- Water Softener Installation: Hard water creates mineral buildup that damages pipes, stains fixtures, and shortens appliance lifespans. GEM provides water softener installation in East Dennis that protects your plumbing while improving how your water feels and performs. We help select the right size and model, install it precisely, and verify efficient operation from day one.
- Water Softener Maintenance: Like any equipment, water softeners need periodic service to function effectively. Our technicians perform thorough checkups, inspecting valves, replenishing salt, and cleaning components to maintain peak performance. Regular maintenance prevents scaling, extends equipment life, and ensures consistent soft water delivery.
- Water Softener Repair: Spots on glassware, dry skin, or stiff laundry suggest your softener isn’t working correctly. GEM’s licensed plumbers diagnose and repair all major brands, resolving issues like salt bridges, depleted resin, or faulty control valves. We restore efficiency quickly so you can enjoy soft, clean water again.
- Water Softener Replacement: Water softeners lose effectiveness over time and eventually stop performing. When repairs no longer make economic sense, GEM helps you select and install a modern unit matched to your home and budget. Newer systems run more efficiently, require less maintenance, and better protect your plumbing.

GEM provides complete septic tank installation, repair, maintenance, and replacement to keep your system working properly and protect your East Dennis property.
Leak Detection
Hidden leaks in older East Dennis homes can cause serious damage if not discovered early.
Aging pipes behind walls, under floors, and in basements make leaks hard to find without specialized equipment. For seasonal properties, leaks that develop during the off-season can cause extensive damage. GEM provides leak detection in East Dennis using acoustic technology, thermal imaging, and other advanced methods to locate leaks precisely with minimal disruption.
Frozen Pipe Repair
Cape Cod winters can freeze pipes quickly, especially in seasonal properties or unprotected areas.
Pipes running through uninsulated walls, basements, or crawl spaces are vulnerable during cold snaps. GEM provides frozen pipe repair in East Dennis using professional thawing equipment and proven techniques to restore water flow safely and prevent burst pipes that cause major damage.
Sewer Lines
Aging sewer infrastructure can lead to recurring problems in East Dennis homes.
Tree roots, deteriorating materials, and outdated underground lines can force wastewater back into homes.

Plumbing FAQs
What winterization steps protect my plumbing during seasonal closure?
Proper winterization includes shutting off the main water supply, draining all lines and the water heater, adding antifreeze to drain traps, and disconnecting outdoor hoses. We recommend professional winterization to ensure nothing is missed.
Does the coastal environment affect plumbing differently?
Yes. Salt air accelerates corrosion on exposed pipes and fittings. Water heater tanks and connections can deteriorate faster in coastal homes. Regular inspections help catch these issues early before they cause leaks or failures.
Why do my drains smell when I first open my seasonal home?
Drain traps dry out when homes sit unused, allowing sewer gases to enter. Running water through all fixtures refills the traps and eliminates the odor. If smells persist, there may be a venting issue or dried-out wax seal.
How often should I service my water heater on the Cape?
Annual maintenance is recommended, including tank flushing and anode rod inspection. Coastal environments can accelerate tank corrosion, so regular service helps extend equipment life and catch problems early.
Can you coordinate with me if I manage my East Dennis property remotely?
Absolutely. We work regularly with property owners who aren’t on-site. We can provide estimates, photos, and updates by phone or email, and coordinate access with property managers or neighbors.
