Plumbing Repair
When plumbing problems disrupt your day, GEM helps Waltham homeowners restore normal function quickly.
Minor issues including dripping faucets, sluggish drains, or toilets running nonstop can escalate into serious headaches. Ignored, they waste water, inflate utility bills, and risk structural damage. Our plumbers handle every repair type, from stubborn clogs and leaking fixtures to damaged supply lines and struggling water heaters. We pinpoint causes, explain them simply, and discuss options before starting any work.
Plumbing Maintenance
Scheduled service identifies small problems before emergency escalation.
Annual inspections prolong pipe, fixture, and water heater lifespans. GEM plumbers inspect for hidden leaks, verify pressure, clear drains, then confirm all connections function properly.
Drain Cleaning
GEM clears blockages using camera inspection plus hydro jetting equipment.
Slow drains typically signal deeper pipe buildup. Grease, soap, hair, plus debris accumulate until water struggles passing through. We pinpoint obstructions, clear them completely, then restore proper drainage.
- 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 Waltham family deserves clean, safe water from every tap.
Water quality concerns vary by location and source. Hard water minerals, chlorine taste, or sediment affect many homes. GEM helps local families improve water quality through dependable, long-lasting treatment solutions. From whole-house filtration through water softening, we make better water easy achieving.

GEM provides water softener installation in Waltham protecting plumbing while improving how water feels and performs. We help select proper size and model, install precisely, then verify efficient operation from day one.
- Water Softener Maintenance: Water softeners require periodic service functioning effectively. Our technicians perform thorough checkups, inspecting valves, replenishing salt, then cleaning components maintaining peak performance. Regular maintenance prevents scaling, extends equipment life, plus ensures consistent soft water delivery.
- Water Softener Repair: Spots on glassware, dry skin, or stiff laundry suggest softeners aren’t working correctly. GEM’s licensed plumbers diagnose and repair all major brands, addressing issues including salt bridges, depleted resin, or faulty control valves. We restore efficiency quickly.
- Water Softener Replacement: Water softeners lose effectiveness through time then eventually stop performing. When repairs no longer make economic sense, GEM helps choose and install modern units matched to homes and budgets. Newer systems operate more efficiently, need less maintenance, then better protect plumbing.

Well Pumps
Your well pump supplies every drop of water your household uses.
When pumps fail, nothing works – no water for drinking, cooking, bathing, or flushing. GEM handles well pump installation, repair, and troubleshooting in Waltham for the rare properties on private well systems.
Septic Tanks
Homes running septic systems need steady maintenance avoiding messy, expensive failures.
Most Waltham properties connect to municipal sewer, but some still operate on septic systems. GEM provides septic-conscious plumbing service understanding how everything affects your system. We coordinate with septic professionals when needed, ensuring work protects your septic investment.
Leak Detection
Hidden leaks show up in Waltham properties and create serious damage when not caught early.
Multi-family buildings and converted industrial spaces present complex plumbing layouts where leaks hide behind walls, under floors, and in basements. GEM provides leak detection in Waltham using acoustic technology, thermal imaging, and other advanced methods to pinpoint leaks precisely with minimal disruption.
Frozen Pipe Repair
Metro West winters deliver cold snaps where frozen pipes become real problems.
Pipes freeze fast during cold stretches, particularly when running through uninsulated walls, basements, or crawl spaces. Multi-family buildings face particular vulnerability. GEM handles frozen pipe repair in Waltham using professional thawing gear plus proven methods to get water flowing safely while stopping burst pipes that cause major damage.
Sewer Lines
Older properties frequently have drain systems that developed issues over decades of use.
Tree roots from mature trees throughout Waltham’s established neighborhoods send roots into aging sewer lines. Deteriorating materials and outdated underground lines create persistent problems. GEM provides sewer line repair in Waltham using advanced camera diagnostics to pinpoint issues accurately and delivers solid repairs or replacements that restore proper flow.
Kitchen & Bath Remodel
Renovating a Waltham kitchen or bathroom demands skilled plumbing for new layouts and modern fixtures.
Whether updating triple-deckers near Moody Street or modernizing condo units, remodeling involves moving water lines, adjusting drains, and installing upgraded fixtures. GEM coordinates with homeowners and contractors to ensure every sink, faucet, shower, and connection is installed correctly and to code.
Garbage Disposals
Busy Waltham households rely on working garbage disposals for easy kitchen cleanup.

Plumbing FAQs
What plumbing issues are common in Waltham triple-deckers?
Triple-deckers and multi-family homes often share plumbing systems with original galvanized pipes prone to corrosion and low pressure. Multiple units create higher usage demands. Drain line issues can affect multiple residents. We assess shared systems and recommend strategic upgrades that solve problems while minimizing disruption to all units.
Can you accommodate my commute schedule?
Absolutely. We understand many Waltham residents commute to Boston, Cambridge, or other Metro West locations. We offer flexible scheduling including early morning, evening, and weekend appointments. Emergency service is available 24/7 when problems can’t wait.
Do you work on converted industrial buildings?
Yes. We regularly service converted mill buildings and industrial spaces throughout Waltham. These properties present unique plumbing considerations including complex layouts, commercial-grade systems, and shared infrastructure. We have experience working in these settings while meeting all residential and commercial code requirements.
How quickly can you respond to emergencies?
We typically arrive within 1-2 hours for emergency calls in Waltham and surrounding Middlesex County communities. Our 24/7 availability means you get help fast regardless of when problems strike – weekends, holidays, or middle of the night.
What causes low water pressure in older Waltham homes?
Low pressure often results from mineral buildup in aging pipes, leaks, worn fixtures, or main line issues. Older multi-families with original galvanized plumbing frequently experience pressure problems as pipes corrode internally, especially on upper floors. A licensed plumber can find the cause and restore proper flow throughout the building.
