11-Month Warranty Inspection Checklist
Your complete guide to documenting issues before your Year 1 warranty expires. What to check each season and the final comprehensive checklist.
Critical Deadline Warning
Your Year 1 (workmanship) warranty coverage expires 12 months from your possession date. Any defects in labor and materials must be reported IN WRITING before this deadline. Issues reported after this date will be denied coverage. Don't wait until the last week - submit your final list at least 30 days before your anniversary date.
Why Seasonal Inspections Matter
Many new build defects only reveal themselves under specific conditions. A home that seems perfect in September may show significant issues after experiencing its first Calgary winter. By checking your home each season, you'll catch issues that would otherwise be missed until after your warranty expires.
The Calgary Factor
Calgary's extreme temperature swings (-30C to +30C), freeze-thaw cycles, and dry winters stress homes in ways that mild climates don't. Issues like thermal bridging, ice dams, foundation cracks, and stucco failures are common here and often appear during specific seasons. Don't wait until month 11 to start looking.
Seasonal Inspection Guide
Fall (Before First Winter)
September - October
Test heating system before you need it
Run furnace to verify operation, check for strange noises or smells
HVACCheck weatherstripping on all exterior doors
Feel for drafts around door edges with door closed
EnvelopeVerify windows close and seal properly
Lock windows and check for air infiltration
EnvelopeInspect exterior caulking before freeze
Gaps expand in cold weather - fix before winter
EnvelopeCheck attic insulation depth and coverage
Verify no gaps, proper depth for R-50
InsulationClean gutters and verify downspout extensions
Prepare for fall rain and winter ice
ExteriorTest sump pump if you have one
Pour water in pit to verify operation
PlumbingVerify HRV/ERV is operational
Critical for winter air quality in tight homes
HVACWinter (First Calgary Winter)
December - February
Monitor for cold spots in walls and floors
Indicates insulation gaps or thermal bridging
InsulationCheck for frost or condensation on windows
Interior condensation indicates humidity/seal issues
WindowsLook for ice dams on roof edges
Indicates attic insulation or ventilation problems
RoofMonitor furnace cycling frequency
Short cycling indicates sizing or airflow issues
HVACCheck for drafts at outlets on exterior walls
Common air leakage point - easy fix if caught
EnvelopeVerify garage heater works if equipped
Test before you really need it
HVACCheck for water stains after snow melts
Roof leaks often appear after heavy snow

March - April
Inspect foundation for new cracks
Freeze-thaw cycles reveal foundation issues
FoundationCheck basement walls for moisture or staining
Spring thaw is prime time for water intrusion
FoundationInspect grading - has soil settled away from foundation?
Settlement is common in first year
ExteriorLook for stucco cracks that appeared over winter
Thermal expansion reveals thin spots
ExteriorCheck roof for damaged or missing shingles
Wind and ice damage becomes visible in spring
RoofVerify sump pump activates during spring melt
Real-world test of system
PlumbingInspect window and door caulking
Winter shrinkage may have opened gaps

CriticalThe 11-Month Final Inspection
Timing Your Final Inspection
Many builders offer a formal 11-month inspection. Even if yours doesn't, you should conduct your own comprehensive review and submit all findings in writing before your warranty expires.
- Month 10: Start your comprehensive inspection
- Month 10.5: Compile and submit your written list to builder
- Month 11: Follow up on builder response and schedule repairs
- Month 11.5: Buffer for any additional issues discovered

How to Submit Your Warranty List
Document Everything with Photos
For each issue, take clear photos showing the problem and its location. Include a reference point (like a ruler or your hand) for scale when relevant. Date stamp your photos.
Create a Numbered List
Format your submission with numbered items. For each: location, description of defect, when you noticed it, and photo reference number. Be specific and factual.
Submit in Writing with Proof of Delivery
Email your list to the builder's warranty department (request read receipt). Also send hard copy via registered mail. Keep copies of everything. The date of submission is what matters.
Request Response Timeline
In your submission, request written response within 10 business days confirming receipt and outlining their repair plan. Follow up if you don't receive acknowledgment.
What If Builder Disputes Items?
Common Builder Responses and How to Handle Them
- "That's normal settling/shrinkage" - Request the specific tolerance standard. Get independent assessment if cracking or movement seems excessive.
- "That's cosmetic, not covered" - Ask for written explanation of what makes it cosmetic vs functional. If it affects performance (drafts, leaks, etc.), it's not cosmetic.
- "We already fixed that" - Review your records. If repair was inadequate, document the continued issue and resubmit.
- "You should have reported earlier" - As long as you're within the warranty period, timing of discovery doesn't invalidate the claim. Some issues take time to appear.
After Year 1: What's Still Covered
Remaining Coverage After Year 1
- Years 1-2: Distribution systems (electrical, plumbing, HVAC)
- Years 1-5: Building envelope (water penetration, exterior cladding)
- Years 1-10: Major structural defects (foundation, load-bearing)
Even after Year 1, continue documenting issues that fall under these categories and submit claims promptly. Don't wait until the next deadline approaches.

Bottom Line
Your Year 1 warranty is valuable protection, but only if you use it. The deadline is firm - issues reported after 12 months will not be covered under workmanship warranty, regardless of merit.
Don't wait until month 11 to start looking. Check your home seasonally, document issues as they appear, and submit your comprehensive list well before your anniversary date. The few hours you invest in this process can save thousands in repair costs.
Keep copies of everything. If you ever need to escalate to the warranty provider or pursue legal remedies, your documentation trail will be critical. A well-organized submission also demonstrates to the builder that you're informed and serious about getting issues resolved.
