Plumbing Repair
When plumbing problems disrupt your day, GEM helps Lexington 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 can damage home structures affecting property value. 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 while protecting your investment. GEM plumbers inspect for hidden leaks, verify pressure, clear drains, and confirm all connections function properly.
Drain Cleaning
GEM clears blockages using camera inspection and hydro jetting equipment.
Slow drains typically signal deeper pipe buildup. Grease, soap, hair, and debris accumulate until water struggles passing through. We pinpoint obstructions, clear them completely, and 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 Lexington 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 to water softening, we make better water simple.
- Water Purifier System Installation: When tap water tastes strange, smells off, or appears cloudy, purification systems make real differences. GEM installs water filtration systems in Lexington designed to remove contaminants, chlorine, and sediment. Our team assesses your water and recommends proper solutions, delivering safe drinking water your family can trust.
- Water Softener Installation: Hard water creates mineral buildup damaging pipes, staining fixtures, and shortening appliance lifespans. GEM provides water softener installation in Lexington protecting plumbing while improving how water feels and performs. We help select proper size and model, install precisely, and verify efficient operation from day one.
- Water Softener Maintenance: Water softeners require 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 softeners aren’t working right. 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 over time and 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, and better protect plumbing.

GEM simplifies upgrading by removing old units, installing efficient new models, and ensuring proper connection and calibration for best performance.

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 Lexington, keeping reliable water supply flowing for homes on private wells.
Septic Tanks
Homes running septic systems need steady maintenance avoiding messy, expensive failures.
Some Lexington properties operate on septic rather than municipal sewer. 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 in Lexington homes can cause serious damage when not caught early.
Premium properties contain complex plumbing systems where leaks hide behind walls, under floors, and in basements, making them tough to spot without special equipment. GEM provides leak detection using acoustic technology, thermal imaging, and other advanced methods to pinpoint leaks precisely with minimal disruption.
Frozen Pipe Repair
Massachusetts winters can freeze pipes quickly, especially in unprotected areas of your home.
Pipes running through uninsulated walls, basements, or crawl spaces are vulnerable during cold snaps. GEM provides frozen pipe repair in Lexington using professional thawing equipment to restore water flow safely and prevent bursting.
Sewer Lines
Mature trees and aging infrastructure in Lexington’s established areas can lead to sewer line trouble.
Tree roots from mature oaks and maples throughout established neighborhoods send roots into aging sewer lines. Deteriorating materials and outdated underground lines create persistent problems. GEM provides sewer line repair in Lexington using advanced camera diagnostics to pinpoint issues accurately and delivers solid repairs or replacements that restore proper flow.
Kitchen & Bath Remodel
Renovating a Lexington kitchen or bathroom requires skilled plumbing for new layouts and upgraded fixtures.
