Before the 1-Year Warranty Expires: The Final New Home Inspection Checklist

Moving into a brand-new construction home in Calgary is an exciting milestone. Most home buyers rely on the 1-Year Alberta New Home Warranty to cover any labor and materials defects that pop up during their first 12 months of ownership.

However, many homeowners make the costly mistake of waiting until the last minute—or relying only on their own eyes—to submit their final year-end repair list. After living in the home through a full cycle of Calgary’s seasonal extremes (from summer downpours to winter freeze-thaw cycles), structural framing settles, materials shrink, and hidden mechanical defects begin to show.

Once your 365-day mark passes, the builder is legally off the hook for labor and material coverage, transferring thousands of dollars in repair costs straight to your wallet.

At NexLevel Home Inspections, home inspectors Pritpal Singh, Navpreet Singh, and Jason perform thorough 11-Month Warranty Inspections to ensure builders fix hidden issues while still under contract. Here is your final new home inspection checklist before your warranty expires.

1. Drywall Cracking vs. Foundation & Structural Settlement

During the first year, a home goes through normal wood shrinkage and initial concrete curing. While minor cosmetic nail pops are common, certain cracking patterns point to structural movement that your builder must correct.

• Cosmetic Shrinkage: Minor hairline cracks around interior door frames or tape seams due to humidity changes.

• Structural Red Flags: Diagonal wall cracks extending from door corners, vertical drywall tears along ceiling joints, or sticking doors that no longer latch cleanly.

• Foundation Soil Settlement: Ground backfill surrounding your foundation wall sinks after a full year of rainfall. Check out why downspouts and soil grading are your first line of defense against foundation water damage.

2. Roof, Attic, and Winter Thermal Performance

Calgary winters push new building envelopes to their limits. Heat escaping into attic spaces causes severe ice damming and concealed roof deck condensation.

What NexLevel inspects during an 11-month roof and attic check:

• Thermal Moisture Anomalies: High-resolution infrared cameras pinpoint insulation gaps and hidden ceiling moisture spots left behind by winter ice dams.

• Attic Ventilation Baffles: Ensures soffit vents haven’t shifted or choked, maintaining healthy airflow. Discover how attic and basement inspections protect indoor air quality.

• Roof Shingle Integrity: Inspects for loose flashing, lifted tabs, or storm wear. Read our guide on missing shingles vs. structural roof failures.

3. Mechanical Systems, HVAC, & Plumbing Checks

Living in the home for 11 months puts real-world stress on plumbing lines, heating equipment, and electrical runs.

• Ductwork Air Leakage: Checks for unsealed duct runs or disconnected heat lines dumping air into unconditioned joist cavities.

• Plumbing Line Leaks & Drainage: Verifies sink traps, water heater relief valves, and basement floor drains for slow leaks or hairline cracks. Review our step-by-step basement inspection checklist from sump pumps to foundation cracks.

• Sump Pump Reliability: Ensures the float switch, check valve, and exterior discharge lines function smoothly before seasonal thaws.

5. Protect Your Home Equity Before Time Runs Out

Submitting an official, third-party inspection report carrying photo evidence and thermal imaging data gives you maximum leverage with your builder’s warranty department.

• Avoid Out-of-Pocket Expenses: Fixing a major insulation void or structural framing issue after Year 1 can cost $5,000 to $15,000+. Learn how easily a basement can hide a $20K problem.

• Hold Builders Accountable: Learn why rushed builder timelines make third-party inspections essential and uncover the 5 most common costly flaws caught in new builds.

• Master Negotiation: Read our guide on how to use home inspection findings to negotiate like a pro.

Calgary Inspector Insight: “Schedule your 1-year warranty inspection during Month 11,” recommends Pritpal Singh. “This gives you plenty of time to review our digital report and submit formal work orders to your builder before your coverage window closes forever.”
