From emergency drain cleaning to full steam boiler replacement, Excellent Plumbing & Heating handles residential and light commercial plumbing and heating work throughout Nassau County and Suffolk County licensed, insured, and done right.

Licensed & Experienced Plumbing and Heating Work Across Long Island

Excellent Plumbing & Heating is a licensed, family-owned company built on real hands-on experience in drain, sewer, and heating systems. Every service we provide — from a clogged kitchen drain to a full sewer line replacement — is handled with the same standard: find the actual cause, fix it properly, and make it last. We're licensed and insured in New York State, and we work on residential and light commercial properties throughout Long Island.

Drain Cleaning & Clog Removal

We fully clear drain blockages using professional equipment — not just a surface-level snake that pushes the problem further down the line. For persistent clogs, we use video camera pipe inspection to find the exact cause before we start.

Sewer Line Repair & Replacement

Root intrusion, collapsed pipe, offset joints, and sewer backups require more than a patch. We diagnose sewer line issues with camera inspection and complete repairs built for long-term performance.

Slab Leak Detection & Repair

A water line break beneath a concrete foundation can cause serious structural damage fast. We locate slab leaks using non-invasive detection methods and complete repairs with minimal disruption to your property.

Steam Boiler Repair & Installation

Steam boilers are common in older Long Island homes and require specialized knowledge to service correctly. We repair, replace, and install steam boilers with the precision and attention to detail these systems require.

Water Line Installation & Repair

Aging, corroded, or failed water supply lines affect pressure, reliability, and overall system performance. We install and repair water lines across Long Island with materials and methods built to last.

Heating System Repair & Replacement

Uneven heating, system inefficiency, and complete heating failures all point to problems that need proper diagnosis — not guesswork. We identify the root cause and complete repairs or replacements that restore reliable performance.

Tank Water Heater Repair & Replacement

No hot water, inconsistent temperatures, slow recovery, or leaks around the unit all signal a water heater problem. We diagnose and repair tank water heaters — or replace them when repair is no longer cost-effective.

Tankless Water Heater Installation

Tankless water heaters provide continuous hot water and better energy efficiency than traditional tank systems. We install and service tankless systems from Navien, Rinnai, Rheem, and other major manufacturers across Long Island.

Video Camera Pipe Inspection

When a drain problem keeps coming back or the cause isn't clear, camera inspection takes the guesswork out. We run a camera through the line to see exactly what's happening before any repair work begins.

Hydro Jetting

For heavy grease buildup, scale, and debris that standard cleaning can't clear, hydro jetting uses high-pressure water to fully flush the line. It's the most thorough drain and sewer cleaning method available.

Plumbing for Remodels & Upgrades

Kitchen and bathroom remodels, water line replacements, and drain system upgrades all require professional plumbing work done correctly from the start. We handle the installation side with the same care as our repair work.

Emergency Plumbing Service

Burst pipes, major sewer backups, and sudden water heater or heating failures can't wait. We provide emergency plumbing and heating service across Long Island — fast response, no shortcuts, problem fixed correctly.
