What Is the Builder's Workmanship Coverage Period for Water Intrusion?

Last updated October 23, 2026

The short answer

Standard Protection Coverage Timelines

Most builder agreements provide one year of coverage for workmanship and materials, which often includes water intrusion from defects like improper flashing or window sealing. A separate agreement for two years might cover systems such as plumbing, electrical, and HVAC, which can be sources of leaks. An agreement for the structure, which is often ten years, may cover water damage stemming from major failures in load-bearing components.

These periods are general guidelines, and your actual documents will list their own specific timelines. The clock starts on the date your home's closing is finalized. It is crucial to understand that water intrusion caused by normal wear and tear or lack of maintenance is typically not covered. Always refer to the written agreement you received at closing for the definitive answer.

What Builder Warranties Usually Exclude

Builder warranties are not all-encompassing. They generally exclude problems arising after you take possession of the home. Damage from storms, faulty appliances you installed, or clogged gutters you failed to clean is your responsibility. Neglect or improper modifications you make can also void coverage for related water issues.

Furthermore, secondary damage is often not covered. If a plumbing leak under the protection agreement causes mold growth or ruins your flooring, the agreement may only pay to fix the leak itself. The resulting water damage cleanup and repairs are typically a separate matter for your homeowner's insurance to address, if covered.

  • Damage from storms, floods, or natural disasters.
  • Problems caused by the homeowner's lack of maintenance.
  • Issues resulting from alterations or repairs done by others.
  • Normal wear and tear on finishes and surfaces.
  • Damage from pests or soil movement.
  • Consequences of using the home for commercial purposes.

How Builder and Home Insurance Differ

Your builder's agreement and your homeowner's insurance policy are completely separate. The agreement covers defects in the original construction for a limited time. Your insurance policy is designed for sudden, accidental events like a burst pipe or a storm-damaged roof that occurs after you own the home. It is common for there to be a gap in coverage. A leak from a construction defect might be a builder agreement issue, while the resulting water damage to your belongings is an insurance claim. Policies vary, and your insurer decides what is covered. You need to navigate both avenues when water intrusion happens.

Steps to Take When You Find a Leak

Your first step is always to stop the water flow if it is safe to do so. Turn off the main water supply or place a bucket under a drip. Then, document everything thoroughly. Take clear photos and videos of the leak's source, the water path, and all damaged areas before any cleanup begins.

Next, immediately review your builder's protection documents to check deadlines and procedures for making a claim. Notify your builder in writing, as specified in the agreement. Simultaneously, you should contact your homeowner's insurance provider to report the incident. Acting quickly on both fronts protects your rights.

  • Stop the water source safely to prevent further damage.
  • Document the leak and all damage with photos and videos.
  • Review your builder's protection documents for claim procedures and deadlines.
  • Notify your builder in writing according to the agreement terms.
  • Contact your homeowner's insurance company to report the incident.
  • Mitigate damage by moving belongings and drying areas if possible.

When to Involve Water Damage Professionals

For any significant water intrusion, involving local water damage pros is a smart move. They can perform a detailed inspection to find the full extent of moisture, even in hidden cavities. This professional documentation can be vital evidence for both your protection and insurance claims, establishing the cause and scope.

The pros use tools like moisture meters and thermal imaging cameras to create a precise assessment report. This report can help determine if the leak is due to a construction defect covered by the protection agreement or another cause. Their findings provide a clear, neutral record that supports your case with the builder or insurer.

Frequently asked questions

What if my builder is out of business?

If the builder is no longer operating, your protection agreement may be difficult to enforce. Check if the agreement was backed by a third-party insurer or a state-run protection program. Your next recourse is typically through your homeowner's insurance policy for the damage, though coverage for the defect itself may not apply.

Can I make repairs before the builder inspects?

You should avoid making permanent repairs before the builder or their representative has inspected the damage. Temporary measures to prevent further damage, like placing a tarp or containing water, are acceptable and often expected. Document your temporary mitigation efforts carefully, as they show you acted responsibly.

Does a home inspection affect the protection agreement?

A pre-purchase home inspection does not void your builder's protection agreement. However, if the inspector noted a potential issue that you did not address, it could later complicate a claim. The agreement covers latent defects that were not reasonably discoverable at the time of sale, not problems you knowingly accepted.
