The 7 Most Common Warranty Claim Mistakes New Homeowners Make

Most homeowners leave warranty coverage on the table. These are the mistakes that cost them their claims — and how to avoid every one.

Most Warranty Issues Go Unreported


Most defects in new construction homes are never formally reported. Homeowners notice problems, assume they are normal, or simply do not know they can make a claim.


The ones who do report are often too late, or make procedural mistakes that undercut their claims.


Here are the seven most common mistakes — and what to do instead.


Mistake 1: Reporting Verbally Instead of in Writing


A phone call to your builder's customer service line does not create a warranty claim. Only written, timestamped notice satisfies the legal requirement of most warranty contracts and state warranty laws.


**Fix:** Submit every claim in writing. Email, certified mail, or a warranty tracking platform like Oluso all create the timestamped record you need.


Mistake 2: Waiting to See If It Gets Worse


Many homeowners notice a crack, a stain, or a door that sticks and decide to monitor it before reporting. Months pass, the warranty period ends, and the defect is no longer covered.


**Fix:** Report as soon as you notice a defect. You can note that it is minor or still developing. The date of first notice is what matters for warranty eligibility.


Mistake 3: Assuming the Builder's Portal Protects You


Some builders have their own warranty management portals. These are controlled by the builder — submissions can be deleted, statuses changed, and timelines disputed.


**Fix:** Keep your own independent record of every claim, even if you also use the builder's system.


Mistake 4: Not Following Up After Submission


Submitting a claim and waiting is not a strategy. A claim that goes unacknowledged for three weeks has effectively been ignored.


**Fix:** If you do not receive written acknowledgment within 5 business days, send a follow-up. Track every follow-up with its date and outcome.


Mistake 5: Accepting Partial Repairs


A builder who fixes the visible symptom without addressing the root cause has not honored your warranty claim. Water staining patched over without finding the leak source will return.


**Fix:** Before closing a claim, confirm that the underlying cause has been resolved, not just the surface manifestation.


Mistake 6: Missing the 11-Month Inspection Window


The most comprehensive warranty coverage — workmanship and materials — expires at one year. An 11-month professional inspection finds issues you can still report under full first-year coverage.


**Fix:** Schedule a third-party home inspection at month 11. It typically costs $300 to $500 and is the highest-ROI action most new homeowners can take.


Mistake 7: Going Adversarial Too Early


Builders have legal teams, arbitration clauses, and patience. Homeowners who become adversarial before exhausting collaborative options often end up worse off.


**Fix:** Be firm but professional in all written communications. Escalation is a tool for after good-faith attempts have failed — not a first response.


Document everything. Follow up consistently. Escalate strategically.
