Your builder warranty typically lasts one year — and the 11-month mark is your last real opportunity to identify defects, document problems, and submit a formal claim before that coverage disappears permanently.
Most new homeowners don’t realize how quickly that window closes or how many issues go unnoticed without a structured walkthrough. This guide gives you a clear, room-by-room process to protect your investment before the deadline.
You will learn what to inspect, how to document findings, what to expect after filing a claim, and when professional support makes the difference between a successful warranty repair and an out-of-pocket expense.
What Is an 11-Month Warranty Inspection?
An 11-month warranty inspection is a systematic review of a newly built home conducted approximately one month before the builder’s one-year warranty expires. Its purpose is to identify construction defects, installation errors, and material failures that the builder is still legally obligated to repair at no cost to the homeowner.
Most new construction warranties follow a tiered structure. The one-year period typically covers workmanship and materials — meaning visible defects, improper installations, and component failures that result from how the home was built. Two-year coverage usually applies to mechanical systems such as plumbing, electrical, and HVAC. Ten-year structural warranties cover load-bearing elements like the foundation and framing.
The 11-month inspection targets the first tier specifically. It is the homeowner’s final opportunity to submit claims under workmanship and materials coverage before that protection ends.
Understanding what this inspection covers is only part of the picture — our home warranty inspection service explains the full scope of builder responsibility, what documentation is required, and how to engage your warranty provider effectively.
Why the 11-Month Mark Is the Right Time to Inspect
Waiting until month 11 is intentional, not procrastination. Inspecting too early — at month three or six — means many defects have not yet had time to appear. Seasonal changes, settling, and normal use reveal problems that are invisible in a brand-new home.
By month 11, the home has experienced at least one full heating and cooling cycle. Drywall has had time to settle and crack. Grout lines have shifted. Roof flashing has been tested by rain. Doors and windows have expanded and contracted through temperature changes. These are the conditions that expose builder errors.
Inspecting at month 11 also gives you time to compile your findings, write a formal claim letter, and allow the builder to schedule repairs before the warranty expires. Submitting at month 12 leaves no buffer for disputes or scheduling delays.
Staying ahead of warranty deadlines is one part of a broader property care strategy — our home maintenance guide covers the full annual schedule homeowners and property managers should follow to protect their investment year-round.
What to Inspect Room by Room
A thorough 11-month warranty inspection covers every system and surface in the home. Work through each area methodically, taking photos and written notes as you go. Do not rely on memory.
Exterior and Roofing
Start outside. Walk the full perimeter of the home and look for cracks in the foundation, gaps in siding, and areas where caulking has separated. Check that grading slopes away from the foundation — improper drainage is a common builder defect that causes long-term water intrusion.
On the roof, look for missing or lifted shingles, exposed nail heads, and gaps around flashing at chimneys, vents, and valleys. Check gutters for proper attachment and slope. Inspect fascia and soffit for gaps or signs of moisture damage.
Roof defects are among the most costly warranty items to address after coverage expires — our roofing inspection services can identify hidden damage, missing flashing, and installation gaps before your builder’s obligation ends.
HVAC, Plumbing, and Electrical Systems
Mechanical systems require more than a visual check. Run every system through a full cycle. Turn on the heating and cooling, run water at every fixture, and test every outlet and switch.
For HVAC, listen for unusual sounds, check that all registers deliver airflow, and verify that the thermostat responds correctly. Mechanical systems are the most frequently disputed warranty items, and catching failures early matters — our HVAC system inspection team checks airflow, refrigerant levels, and installation quality against builder specifications.
For plumbing, run every faucet, flush every toilet, and check under every sink for moisture. Slow drains, water pressure inconsistencies, and pipe joint failures are common plumbing warranty issues — our plumbing warranty issues checklist covers every system component your inspector should verify before the deadline.
For electrical, test every outlet with a plug-in tester, check that all breakers are labeled correctly, and verify that GFCI outlets in bathrooms and kitchens trip and reset properly.
Interior Walls, Ceilings, and Floors
Walk every room and look at walls and ceilings in raking light — light that hits the surface at a low angle reveals imperfections that are invisible under normal lighting. Look for nail pops, tape separation, cracks at corners, and uneven texture.
Cracks, nail pops, and tape separation are standard warranty items that builders must address — our drywall and ceiling repairs team documents and corrects these defects as part of a complete pre-deadline inspection.
On floors, walk slowly and listen for squeaks. Look for gaps between planks, uneven transitions between rooms, and tiles that rock or sound hollow when tapped. Gaps, squeaks, and uneven surfaces in new construction flooring are often covered under builder warranties — our flooring defect inspection service identifies installation errors before your coverage window closes.
Doors, Windows, and Entry Points
Open and close every door and window in the home. Doors should latch without force, swing freely without dragging, and seal completely when closed. Doors that stick, fail to latch, or show frame separation are common new-construction defects — our door alignment check service documents every entry point so nothing is missed before your warranty expires.
For windows, check for fogged glass between panes, which indicates a failed seal. Look for drafts by holding your hand near the frame on a cold day. Check that every window opens, closes, and locks as intended. Fogged glass, drafts, and improper alignment are warranty-eligible window defects that are easy to miss without a systematic check — our window seal inspection covers every opening in the home for air, water, and operational issues.
How to Document and Report Warranty Issues
Documentation is what separates a successful warranty claim from a disputed one. Every defect you find needs a written description, a photograph, and a location reference.
Use a room-by-room log. For each item, write the location, describe the defect in plain language, note when you first observed it, and attach at least one clear photograph. Date every entry. If a defect worsens over time, add follow-up photos with updated dates.
Once your inspection is complete, compile your findings into a formal written notice to your builder. Address it to the warranty department or the contact named in your warranty documents. List every defect clearly and request a written response with a repair timeline. Send it by certified mail or email with read receipt so you have proof of delivery.
Keep copies of everything — your original notice, the builder’s response, and any repair records. If the builder disputes a claim or fails to respond, your documentation is your evidence.

What Happens After You Submit Your Warranty Claim
After you submit your claim, the builder’s warranty department will typically schedule a walkthrough to verify the reported defects. Response timelines vary by builder, but most contracts specify a window — often 10 to 30 days — for acknowledgment and a separate window for repair completion.
During the builder’s walkthrough, be present. Walk through every item on your list and confirm that the representative has seen and noted each one. Ask for written confirmation of which items are accepted and which are disputed.
If the builder accepts the claim, repairs are typically scheduled within the warranty period. If repairs are not completed before the warranty expires, document that the claim was submitted and acknowledged before the deadline — this preserves your right to have the work completed even after the coverage period ends.
If a claim is denied, review your warranty documents carefully. Many warranties include a dispute resolution process. In some cases, a third-party inspection report strengthens your position significantly.
How a Professional Inspection Strengthens Your Claim
A self-conducted inspection is valuable, but a professional walkthrough adds credibility that a builder’s warranty department takes more seriously. A trained inspector knows where to look, what qualifies as a warranty-eligible defect under standard construction codes, and how to document findings in a format that supports a formal claim.
Professional inspectors also identify issues that homeowners commonly miss — improper flashing details, subtle framing irregularities, and mechanical system performance issues that only appear under specific test conditions.
A documented professional walkthrough gives your claim credibility and ensures nothing is overlooked — our professional warranty inspection service is designed specifically to support homeowners at the 11-month mark, giving you a complete, documented record before your builder’s obligation expires.
If you are managing multiple properties or a new development, a professional inspection at the 11-month mark is not optional — it is the most cost-effective way to protect your investment before coverage ends.
Conclusion
An 11-month warranty inspection is one of the most valuable steps a new homeowner can take to protect their property. Catching defects before the builder’s coverage expires means repairs happen at no cost — defects found after the deadline become your expense.
A systematic room-by-room approach, thorough documentation, and a formal written claim give you the strongest possible position when dealing with a builder’s warranty department.
At Mr. Local Services, our inspection and home maintenance professionals are ready to walk through your property, document every finding, and help you submit a complete, credible warranty claim before your deadline arrives.
Frequently Asked Questions
What does a builder’s one-year warranty typically cover?
A builder’s one-year warranty generally covers defects in workmanship and materials — including drywall, flooring, roofing, doors, windows, and exterior finishes. It does not typically cover normal wear, homeowner damage, or cosmetic issues that fall below a defined threshold.
How long does an 11-month warranty inspection take?
A thorough 11-month warranty inspection of an average single-family home takes two to four hours. Larger homes or properties with multiple mechanical systems may require additional time to test every component and document findings properly.
Can I do the inspection myself or do I need a professional?
You can conduct the inspection yourself using a room-by-room checklist, and many homeowners do. However, a professional inspector brings technical knowledge, testing equipment, and documentation experience that strengthens your claim and reduces the risk of missing covered defects.
What if the builder refuses to make the repairs?
If the builder denies a valid claim, review your warranty documents for the dispute resolution process. A written record of your original claim submission, the builder’s response, and any professional inspection report gives you the strongest basis for escalation or legal action.
How do I know if a defect is covered under the warranty?
Defects caused by construction errors, improper installation, or material failure are typically covered. Damage caused by the homeowner, normal settling within accepted tolerances, or cosmetic issues below the warranty threshold are usually excluded. When in doubt, submit the claim in writing and let the builder’s warranty department make the determination.
What should I do if I find a defect after the warranty expires?
Once the one-year workmanship warranty expires, repair costs become the homeowner’s responsibility unless the defect falls under a longer coverage period — such as a two-year mechanical warranty or a ten-year structural warranty. Document the defect, review your full warranty agreement, and consult a contractor to assess repair options.
Is an 11-month inspection the same as a home inspection?
No. A standard home inspection is conducted before purchase to assess the condition of an existing property. An 11-month warranty inspection is conducted on a newly built home to identify construction defects before the builder’s coverage expires. The purpose, scope, and documentation requirements are different.
