Plumbing Leak Basics

Early detection of plumbing leaks is essential to preventing costly structural and mold damage. Watch for:

  • Water stains on ceilings, walls, or floors
  • Visible mold or mildew patches
  • Unexplained spikes in your water bill
  • Persistent musty or earthy odors

Some examples of the most common causes include the following:

  • Many pre-war and mid-century buildings still rely on galvanized or even lead service lines that crack, pit, and leak as they deteriorate
  • Frozen pipes and service lines
  • Compromised masonry, faulty flashing, or shared risers often route water into multiple apartments, especially in older high-rises

New York homeowners have a legal duty to mitigate further loss and promptly notify their insurer of the damage. Policies that require “prompt” or “immediate” notice can allow carriers to reduce or deny payment if delays prejudice their investigation. Once your insurer provides its proof-of-loss form, you generally have 60 days to submit the sworn statement under N.Y. Insurance Law § 3407.

Who Can Be Held Legally Liable for Plumbing Leaks in NY?

Landlords must repair and compensate tenants when water intrudes from building plumbing or another apartment. New York’s Warranty of Habitability (Real Property Law § 235-b) makes this duty non-waivable.

Alternatively, in co-ops and condos, the board or association must fix leaks that originate in common elements (roofs, risers, façade lines) and address any resulting damage to units.

Under DEP rules, the property owner is on the hook for frozen or burst service lines in one—to four-family homes and any interior pipe bursts linked to poor maintenance or inadequate heating.

Where a sudden burst damages an owner-occupied dwelling, the owner’s insurer should pay, provided the homeowner acts promptly to mitigate, document, and notify the carrier, as required by policy conditions.

Responsibilities of Parties Involved

Homeowners

  • Maintain and protect plumbing systems. The NY Department of Environmental Protection places full responsibility for service-line maintenance, winterizing, and repairs on the property owner; if a line freezes or bursts, the owner must hire a Licensed Master Plumber to correct the condition.
  • Mitigate and notify. New York’s Warranty of Habitability obligates owners (and landlords) to remedy hazardous conditions quickly, while insurance policies require prompt notice and reasonable steps to limit additional damage.

Contractors & Licensed Plumbers

  • Permitting and code compliance. Only Licensed Master Plumbers may pull permits and perform plumbing work in NY; they must follow the NY Plumbing Code and Administrative Code provisions governing installation, testing, and repairs. Failure to obtain permits or meet code can expose the plumber—and often the general contractor—to negligence claims and DOB penalties.
  • Duty of workmanship. Boards in co-ops and condos routinely require proof of licensure and insurance before allowing a plumber to open common-element risers; shoddy work that causes downstream leaks can trigger claims from both the board and affected owners.

Manufacturers & Suppliers

  • Product safety and liability. Defects in pipes, valves, water heaters, or fittings can trigger strict liability under New York product liability law. While most homeowners' policies pay for the resulting water damage, they do not usually cover replacement of the defective part, exposing manufacturers to subrogation suits by insurers or direct claims by owners.

How to Navigate Insurance Coverage for Plumbing Leaks in New York

It’s important that you know your policy exclusions. For example, standard HO-3 and HO-6 policies sold in New York cover “sudden and accidental” water discharges, such as a pipe that bursts without warning, but they routinely exclude damage caused by long-term seepage, wear-and-tear, or neglected maintenance. Flooding from surface water is also carved out and must be insured separately (Customer Homeowners FAQ | Department of Financial Services).

Also, you’ll need to be aware of subrogation and the “made-whole” rule:

  • Once your insurer pays for repairs, it may pursue the party responsible for the leak (for example, a negligent plumber or neighboring owner)
  • In New York, an insurer’s right to recover is generally postponed until you have been fully compensated—an equitable principle known as the made-whole doctrine

New York also bars an insurer from suing its insured under another section of the same policy, protecting co-op boards, landlords, or contractors who are additional insureds from being sued by the carrier that just paid the water-damage claim.

Legal Strategies and Litigation

When an insurer delays, underpays, or outright denies your water-damage claim, Vargas Gonzalez Delombard, LLP deploys a phased, pressure-building approach designed to resolve the dispute quickly, yet always keeps the case trial-ready.

When the fight is purely over valuation, we trigger appraisal, appoint seasoned public adjusters and construction estimators on your behalf, and demand a neutral umpire if the carrier low-balls the award. If negotiation stalls, we sue in Supreme Court for breach of contract and declaratory relief. We may pursue consequential damages to penalize slow payers.

From the first demand letter through trial, VGD treats every case as if it will go the distance. That trial-ready posture drives favorable settlements, and because we advance all costs and work on contingency, you pay legal fees only after you recover.
