Piping Repair

Piping Repair & Replacement in NYC

Whether you have a broken water pipe, a corroded gas line, or aging supply lines that need upgrading, Karl's licensed master plumbers handle all types of piping repair and replacement for residential and commercial properties across New York City.

Common Causes of Pipe Damage

Corrosion

Pipes in contact with soil or moisture corrode over time, especially cast iron and galvanized steel pipes common in NYC's older buildings. Corrosion weakens pipe walls, leading to pinhole leaks that can cause water damage behind walls and under floors. If your building was built before 1980, your pipes may be approaching the end of their lifespan.

Frozen & Burst Pipes

Water expands when it freezes, putting tremendous pressure on pipe walls. NYC winters regularly produce conditions that cause pipes to burst, especially in unheated areas like basements, crawl spaces, and exterior walls. A burst pipe can release hundreds of gallons of water per hour. Learn more about frozen and burst pipe repair.

Root Intrusion

Tree roots naturally seek water sources and can infiltrate pipe joints, cracks, and connections. Once inside, roots grow and expand, eventually cracking or crushing the pipe entirely.

Age and Wear

All piping materials have a finite lifespan. Galvanized steel lasts 20-50 years, copper lasts 50-70 years, and cast iron lasts 50-100 years. NYC has some of the oldest residential plumbing infrastructure in the country, and many buildings are overdue for repiping.

Pipe Materials We Work With

• Copper — the gold standard for water supply lines, durable and corrosion-resistant
• PEX — flexible cross-linked polyethylene, ideal for retrofits in tight spaces
• PVC/CPVC — lightweight plastic piping for drain lines and cold water supply
• Cast iron — common in older NYC buildings for drain and sewer lines
• Galvanized steel — found in pre-1960s buildings, prone to corrosion and reduced water flow
• Black iron — used for gas lines throughout NYC
