When you buy a newly constructed home, you're not just investing in a building—you're relying on promises about quality and durability. New construction warranties protect you when things go wrong, but understanding exactly what's covered (and what isn't) can save you thousands in unexpected repairs.
What a New Construction Warranty Actually Covers
New construction warranties typically come in layers, each protecting you against different types of defects for different time periods. The most common structure includes a one-year warranty covering defects in workmanship and materials, a two-year warranty on major systems like plumbing and electrical, and a ten-year structural warranty on the home's frame and foundation.
During that critical first year, builders are responsible for fixing cosmetic issues—squeaky doors, paint touch-ups, minor drywall cracks—as well as functional problems like appliances that don't work. Most builders schedule a walkthrough at 30 days, six months, and one year to document and address these items.
The Two-Year Systems Warranty
This middle tier covers major mechanical and operational systems. If your HVAC system fails at 18 months, that's covered. A water heater malfunction at 20 months? The builder should repair or replace it. Plumbing leaks, electrical issues, and built-in appliance failures typically fall under this umbrella.
Keep detailed records of any problems you notice during this window. Builders often push back on claims filed late, arguing the defect should have been discovered earlier. Document issues with photos and dates as soon as you spot them.
The Ten-Year Structural Warranty
The longest coverage applies to structural elements: the foundation, framing, roof structure, and load-bearing walls. This doesn't cover roof shingles or weatherproofing—only the structural integrity underneath. A foundation crack that affects the home's stability gets covered; cosmetic concrete spalling does not.
Structural warranties are often the toughest to enforce because determining "defect" versus "normal settlement" requires expert inspection. Hire an independent structural engineer ($800–$1,500) if you suspect a serious problem before filing a claim.
What's Explicitly NOT Covered
New construction warranties have significant gaps. Landscaping, driveways, and exterior concrete typically aren't included. Weather damage, water intrusion from poor maintenance, and wear-and-tear from normal use fall outside coverage. If you fail to maintain the HVAC system and it breaks, that's on you.
Many warranties exclude problems caused by homeowner modifications, damage from accidents, and issues stemming from settling (even if it seems excessive). Some builders also exclude coverage if you don't perform recommended maintenance—so keep records of HVAC servicing and other routine care.
How to Protect Yourself
Before closing, request and read the actual warranty document, not just a summary. Ask your builder:
- Does the warranty transfer to future buyers?
- What's the claims process and timeline?
- Who determines if something qualifies as a defect?
- Are there caps on claim amounts?
At closing, get copies of all warranty documents, maintenance schedules, and manufacturer warranties for appliances and systems. Create a home file with builder contact information, warranty expiration dates, and serial numbers for major appliances.
During the first year, document everything. Take photos of any cracks, water stains, or malfunctioning systems. Report issues in writing (email or certified mail) rather than casual conversations. Don't assume something minor will go away—small water infiltration issues often worsen over time.
Warranty Transferability and Resale
Standard new construction warranties transfer to the next owner, but coverage often decreases. The second owner might receive a two-year total coverage instead of the full ten-year structural warranty. This matters when selling—clarify what you're transferring in your listing to attract informed buyers.
Some premium builders or communities offer extended warranties (15 or 20 years) as a sales tool. These cost more upfront but provide peace of mind, especially if you plan to stay long-term.
Where to Start
When evaluating builders, don't just compare prices—compare warranty offerings. A builder offering comprehensive coverage with a clear claims process is worth a premium. Services like Mercoly help you compare trusted new construction builders in your area and review their warranty terms side-by-side, making it easier to find a reliable partner before you commit.
Frequently Asked Questions
Q: Can a builder refuse to honor a warranty claim? Yes, if they determine the defect falls outside coverage terms or was caused by homeowner neglect. This is why documentation and hiring independent inspectors for serious issues is critical.
Q: What happens if the builder goes out of business? You lose coverage. Some states require builders to post bonds guaranteeing warranty claims, but enforcement varies—check your state's new construction regulations.
Q: Should I pay for a home inspection even with a new construction warranty? Absolutely. A third-party inspection at 30 days catches problems your builder might overlook, creating a documented record for warranty claims later.
