New home warranty inspection: What it is and why the 11-month check matters

What a new home warranty inspection is and when to schedule one

A new home warranty inspection is a focused review of a newly built home near the end of the first-year warranty period to document defects, workmanship issues, and systems that are not performing as expected. Canadian new home warranties are commonly described with tiered coverage such as "1-2-5-10" for different defect categories, and buyers are advised to document anything that does not work while the warranty applies to preserve repair rights and claims. For an overview of post-purchase steps for new builds see Moving Into a New Build in Canada. Moving Into a New Build in Canada.

In Alberta and similar provinces, many inspectors and advisors recommend an "11-month" inspection as the last practical opportunity to capture first-year defects before warranty coverage ends. The 11-month check gives you time to report defects, let the builder respond, and, if necessary, escalate with the warranty provider before deadlines are reached. For Alberta-specific context see a practical explanation of the Alberta 11-month inspection. Alberta new home warranty: Why you need an 11-month inspection.

Why the 11-month inspection is commonly recommended in Alberta

The 11-month inspection is not a legal magic date, but it is a practical scheduling rule. It is recommended because many defects reveal themselves only after seasonal use, and an inspection at this time leaves a short but actionable window to arrange repairs while warranty obligations are clearer. Practical pre-delivery and possession checklists use the same room-by-room attention to detail that an 11-month review replicates for warranty protection. For a sample PDI checklist and timing considerations see The Ontario New-Home PDI. The Ontario New-Home PDI.

Room-and-systems checklist you can use at 11 months

Use this compact, systems-organized checklist to prioritise what to test, photograph, and record. The structure follows common inspection priorities for Canadian buyers and is practical for builder meetings or warranty claims; BubbleWatch recommends organizing checks by access, materials, safety, and warranty actions when documenting problems. Home Inspection Checklist Canada 2026.

Roof and exterior checks (quick list)

Visual condition of roof coverings, missing or damaged shingles or membranes; note sagging or ponding on low-slope areas.
Flashing and sealants at chimneys, wall intersections and penetrations for gaps or separation.
Gutters and downspouts for secure attachment, blockages and proper downflow to drainage paths.
Siding, cladding and trim for cracks, separation, or staining that may indicate water intrusion.
Exterior doors, garage door operation and weatherstripping for alignment and secure seals.

Structure, foundation and drainage (quick list)

Visible foundation cracks, uneven or separating exterior walkways, and stair or deck connections.
Grading around the house and surface drainage that could direct water toward the foundation.
Basement or crawlspace dampness, efflorescence, or water stains on walls and floors.

Plumbing and wet areas (quick list)

Test all faucets, sinks, tubs and showers for leaks, drainage speed, and consistent hot water delivery.
Toilet operation and secure mounting; look for wobble or running after flushing.
Check visible plumbing in mechanical rooms for drips, loose connections or corrosion.
Look for water stains, bubbling paint, mould odour and caulking failures around fixtures.

Electrical and HVAC checks (quick list)

Confirm breakers are labelled and operate, test a sample of outlets and GFCI/AFCI protection.
Inspect electrical panel for loose cover, rust, or heat evidence; note any odour or discoloration.
Test heating and cooling operation across modes and thermostats, and observe unusual noises or failure to reach set temperatures.
Check ventilation, bathroom exhaust and dryer vent routing for blockages or poor flow.

Interior finishes, doors, windows and insulation (quick list)

Windows for smooth operation, secure locks, fogging between panes and consistent sealing.
Interior doors for sticking, alignment and hardware function.
Floor and wall finishes for cracking, gaps, uneven transitions and paint defects.
Attic and insulation presence and condition where accessible; look for gaps around penetrations and consistent coverage.

Decision rules: When to contact the builder and when to hire a certified inspector

Not every cosmetic issue requires an immediate third-party inspection. Use these short rules to decide whether to notify the builder directly, engage a certified inspector, or do both.

Contact the builder first for minor cosmetic defects, missing finishes, or incomplete items where warranty response is routine and straightforward, and you expect a prompt repair.
Hire a certified inspector when you find any safety hazard (electrical sparking, gas smell), suspected structural movement (new steep cracks, doors sticking across many rooms), recurring leaks, or a problem that the builder disputes.
Do both if the issue is serious but you want an independent, documented record before repairs begin, for example when waterproofing, foundation, roofing or mechanical system performance is in question.

Authoritative checklist frameworks recommend third-party documentation for unclear causes or safety concerns and for situations where you expect to rely on evidence if the builder or warranty provider challenges the claim. BubbleWatch and Alberta-focused inspection guides recommend an inspector when access, testing, or specialist tools are needed to confirm a defect. Singh Home Inspections explains why the 11-month check often triggers professional involvement.

How to document defects and present a warranty claim

Good documentation makes a claim actionable. Use these steps when you photograph and report issues.

Take dated photos and short video clips that show the defect and surrounding reference points. Use your phone's timestamp or a file naming convention with the date.
Record where the problem is located (room, elevation, closest fixed reference) and describe what you observed, when it started, and whether it is getting worse.
Note environmental context: recent heavy rain, freezing cycles, or construction activity that may relate to the issue.
Send defects to the builder in writing (email) with attachments and request a written response or work order number; keep copies for warranty escalation.
If you hire an inspector, ask for a dated report with photos and prioritised recommendations you can share with the builder or warranty provider.

Pre-delivery and warranty checklists emphasise the same documentation approach: clear photos, concise descriptions, and written communication to create a defensible record. For an example of how to frame items before possession see The Ontario New-Home PDI. The Ontario New-Home PDI.

Common objections buyers raise and objective decision criteria

Two common hesitations are cost and the belief that the builder will fix everything if notified. Use the following objective criteria to decide:

Hire an inspector if there is any safety risk, suspected structural defect, repeated failures after builder visits, or when the builder's proposed fix is vague or temporary.
Report to the builder first for single, straightforward cosmetic repairs where the builder has acknowledged responsibility and provided a clear timeline.
Time-sensitive action is required when repair scheduling could push fixes past warranty deadlines, so document and follow up promptly.

These decision points reflect inspection industry practice for Canadian buyers and the practical timing advice used in Alberta. BubbleWatch and local inspectors recommend using measurable criteria such as safety, recurrence, and structural evidence to decide when to escalate.

Frequently asked questions

What is a new home warranty inspection and who should get one?

A new home warranty inspection is an independent review near the end of the first-year warranty period to document defects and system performance. Buyers of new construction, their representatives, or realtors often get one when concerns exist about workmanship, recurring leaks, HVAC performance, or when an objective record is needed for warranty claims.

When should I schedule an 11-month inspection in Alberta?

Schedule it close to the 11-month mark so you have time to report issues and allow repairs or warranty actions before critical deadlines. Local inspectors recommend the 11-month window as the last practical chance to document first-year defects; book so there is time for follow-up. Singh Home Inspections covers why this timing matters in Alberta.

Will the builder fix every defect I report after an inspection?

Builders commonly address many warranty items, but acceptance depends on cause, whether the issue falls under warranty coverage, and the builder's assessment. An independent inspection creates documentation to support your claim, and if a dispute arises you can present the inspector's report along with your photos and correspondence.

Do I need thermal imaging or drone roof checks for a warranty inspection?

Thermal imaging helps reveal hidden moisture, insulation gaps, and HVAC anomalies; drone roof inspections give clear views of coverings and flashing when safe access is limited. Use these tools when leaks, inconsistent thermal performance, or roof access issues are suspected. Spot On can include these options in an 11-month inspection. Spot On Inspections & Reviews.

How fast will I get the inspection report and what should it include?

Look for a dated, photo-rich report that describes each deficiency, its location, priority for repair, and recommended next steps. A same-day digital report is helpful when timelines are tight so you can notify the builder immediately; Spot On advertises same-day reporting with photos and clear recommendations.
