When to Schedule Your New Construction Warranty Inspection in Mankato
By Closer Look Home Inspectors | (507) 721-3820
If you purchased a newly built home in Mankato or one of the surrounding communities, your builder's warranty provides valuable protection, but only if you use it. The most important inspection you can schedule is the 11-month warranty inspection, timed just before your typical 1-year builder warranty expires.
Why the 11-Month Inspection Matters
New homes settle, shift, and reveal issues over their first year that weren't apparent at closing. By month 11, the home has experienced a full cycle of Minnesota weather—the extreme cold of winter, spring moisture, summer heat, and fall temperature swings. This is when issues become visible.
Common 11-Month Findings in Mankato New Construction
- Settling cracks: Drywall cracks around windows, doors, and ceiling/wall joints as the home settles on Blue Earth County's clay soils
- Grading and drainage issues: Builder-installed grading that has settled, creating water drainage toward the foundation instead of away from it
- Caulk separation: Exterior caulk around windows, doors, and trim that has dried, cracked, or separated during temperature cycling
- HVAC balancing: Rooms that are consistently too hot or too cold, indicating ductwork or system balancing issues
- Roof and flashing: Shingle alignment issues, flashing gaps, and gutter problems that developed after initial construction
- Plumbing leaks: Slow leaks under sinks, around toilets, or at shower/tub surrounds that only appear with regular use
What to Do With the Report
Submit our detailed inspection report to your builder as a warranty claim list. Most builders are responsive to documented, professional findings. Address items in priority order, focusing on water intrusion, structural concerns, and safety issues first. Your warranty requires you to report issues before it expires—don't wait.
Frequently Asked Questions
When exactly should I schedule the warranty inspection?
Schedule between months 10 and 11 of your first year. This gives you time to submit warranty claims before the 12-month expiration and allows the builder time to schedule repairs.
My builder did a final walkthrough—isn't that enough?
The builder's walkthrough typically happens at or near closing, before the home has experienced a full weather cycle. Many issues only appear after months of use and seasonal changes. A professional 11-month inspection catches what the initial walkthrough cannot.
How much does a warranty inspection cost?
Warranty inspections are priced similarly to standard home inspections based on home size. The cost is minimal compared to the repairs it can identify while still covered under warranty. Call (507) 721-3820 for current pricing.
