Your builder warranty expires at 12 months — and the 11-month walkthrough is your last real opportunity to catch defects, document problems, and file a claim before that window closes permanently. Most new homeowners miss this deadline simply because no one told them it existed. A thorough walkthrough conducted one month before expiration gives you time to inspect every system, compile a complete defect list, and submit a formal claim while your coverage is still active.
This deadline matters because builder warranties follow a strict timeline, and issues discovered after the 12-month mark become your financial responsibility entirely.
This guide covers what to inspect, how to document problems, how to submit your claim, and what to expect after your builder receives it.
What Is an 11-Month Warranty Walkthrough?
An 11-month warranty walkthrough is a structured inspection of your home conducted approximately one month before your builder’s one-year warranty expires. It gives you a final opportunity to identify construction defects, workmanship issues, and system failures that fall within your warranty coverage — and to report them formally before the deadline passes.
Most new construction homes in the United States come with a builder warranty that follows a tiered structure. The first year typically covers workmanship and materials. Years two through ten cover structural components and major systems depending on the builder and state requirements. The 11-month walkthrough targets that first-year coverage tier specifically, which is the broadest and most accessible layer of protection you have.
The walkthrough is not a casual visual check. It is a methodical room-by-room, system-by-system review designed to surface every issue that qualifies for a warranty repair. Anything you miss during this inspection — or fail to report in writing before the 12-month mark — will not be covered.
Understanding what your walkthrough covers starts with knowing the full scope of your builder’s obligations — our new home warranty guide explains exactly what builders are required to cover, for how long, and what falls outside standard protection.
Why the 11-Month Mark Is the Right Time to Act
Waiting until month 12 is too late. By the time most homeowners realize their warranty is expiring, the deadline has already passed. Conducting your walkthrough at month 11 gives you a full 30-day buffer to complete the inspection, compile your defect list, and submit your claim with enough time for the builder to acknowledge receipt before coverage ends.
Many of the defects that surface in the first year are not immediately obvious. Settling cracks in drywall, grout separation in tile, minor roof flashing gaps, and HVAC performance issues often take months to become visible. By month 11, these problems have had enough time to develop to the point where they are identifiable — but your warranty is still active enough to cover them.
There is also a practical reason to act early. Builders receive a high volume of warranty claims in the final weeks before expiration. Submitting your list at month 11 rather than month 12 gives your claim more attention and reduces the risk of administrative delays that push your submission past the deadline.
Staying ahead of warranty deadlines is easier when you have a structured plan — a complete home maintenance checklist helps you track seasonal tasks and time-sensitive inspections so nothing slips through before coverage ends.
What to Inspect During Your 11-Month Walkthrough
A thorough 11-month walkthrough covers three primary areas: structural and exterior systems, interior systems and finishes, and mechanical, electrical, and plumbing systems. Work through each area methodically and record every issue you find, no matter how minor it appears.
Structural and Exterior Systems
Start outside. Walk the full perimeter of your home and inspect the foundation for cracks, gaps, or signs of settling. Check the grading around the foundation to confirm water drains away from the structure rather than pooling against it. Inspect all exterior caulking around windows, doors, and penetrations for gaps or separation.
Move to the roof. Look for missing, lifted, or improperly installed shingles. Check flashing around chimneys, vents, and valleys. Inspect gutters and downspouts for secure attachment and proper slope. Examine soffits and fascia for gaps, rot, or paint failure.
Roof defects are among the most expensive post-warranty repairs a homeowner can face, which is why scheduling a professional roofing inspection before your builder warranty expires can save thousands in out-of-pocket costs.
Also inspect the garage, driveway, walkways, and any exterior structures included in your build. Document cracks in concrete flatwork, gaps in expansion joints, and any drainage issues on the property.
Interior Systems and Finishes
Move through every room systematically. Inspect all drywall surfaces for cracks, nail pops, tape separation, and uneven texture. Check corners and ceiling lines for gaps or separation. Look at tile work in bathrooms and kitchens for cracked grout, loose tiles, and gaps at transitions.
Examine all interior doors for proper alignment, smooth operation, and secure hardware. Check windows for proper sealing, smooth operation, and any signs of condensation between panes, which indicates a failed seal. Inspect flooring for squeaks, gaps, uneven seams, and any lifting at edges or transitions.
Cracks, nail pops, and uneven seams in walls and ceilings are common warranty items that are easy to overlook — our drywall and ceiling repairs explains what qualifies as a defect and what to flag during your walkthrough.
Check all cabinetry for alignment, secure mounting, and smooth drawer and door operation. Inspect countertops for chips, cracks, and gaps at backsplash seams. Look at all painted surfaces for runs, thin coverage, and areas where the finish has not adhered properly.
Mechanical, Electrical, and Plumbing Systems
Test every electrical outlet and switch. Verify that GFCI outlets in bathrooms, kitchens, and garages trip and reset correctly. Check all light fixtures for secure mounting and proper operation. Inspect the electrical panel for any labeling issues, loose breakers, or signs of heat damage.
Run every faucet and check water pressure throughout the home. Test all drains for proper flow. Flush every toilet and check for running or slow fill. Inspect under all sinks for signs of moisture, drips, or improper connections. Check the water heater for leaks, proper venting, and temperature setting.
Heating and cooling systems are among the most frequently flagged items in builder warranty claims — learning what to look for during an HVAC system inspection ensures you catch performance issues before your coverage window closes.
Run your HVAC system in both heating and cooling modes. Listen for unusual sounds, check airflow at every register, and verify that the thermostat responds correctly. Inspect all accessible ductwork for gaps, disconnections, or improper support.
How to Document Issues Before Your Warranty Expires
Documentation is what turns a walkthrough into a valid warranty claim. A verbal report or informal email is not sufficient. You need a written record that is specific, dated, and supported by photographic evidence.
For every defect you identify, record the exact location using room name and wall orientation (for example, “master bathroom, east wall, lower left corner”). Describe the issue clearly and specifically. Note when you first observed it if you noticed it before the walkthrough. Take multiple photographs of each defect from different distances — one wide shot showing the location in context and one close-up showing the defect clearly.
Organize your documentation into a single written list before you submit it. Number each item. Include the location, description, and photo reference for every entry. Keep copies of everything you submit, including the submission date and the method used to deliver it to your builder.
If you want a second set of eyes before submitting your warranty list, a skilled handyman can walk through your home with you and identify issues you may have missed — our handyman inspection support team is available to help you build a thorough, well-documented claim.
How to Submit a Warranty Claim the Right Way
Review your warranty documentation before you submit. Most builder warranties specify the exact method and address for submitting claims. Some require written notice by certified mail. Others accept email or an online portal. Using the wrong submission method can create disputes about whether your claim was received on time.
Submit your complete defect list in writing. Do not submit items verbally or in a phone call without following up with written confirmation. Your written submission creates the official record that your claim was filed before the warranty expired.
Include your name, address, contact information, and the date of your walkthrough at the top of your submission. Attach all photographs clearly labeled to match your defect list. Request written confirmation of receipt from your builder.
If you notice signs of moisture or leaks during your walkthrough, our water damage documentation specialists can assess the extent of the problem before you submit your report, ensuring your claim accurately reflects the full scope of any water intrusion issues.
Keep a copy of your complete submission package — the defect list, all photographs, and any correspondence — in a dedicated file. You will need this record if any disputes arise during the repair process.
What Happens After You Submit Your Claim
After you submit your warranty claim, your builder is required to acknowledge receipt and schedule an inspection of the reported defects. Response timelines vary by builder and by state, but most warranty agreements specify a response window of 10 to 30 days.
During the builder’s inspection, a representative will review each item on your list and determine whether it qualifies for warranty repair. Some items will be approved immediately. Others may be disputed if the builder believes the defect falls outside warranty coverage or was caused by homeowner action rather than construction error.
Once repairs are approved, the builder will schedule the work. Keep records of all repair dates, the names of contractors who performed the work, and the condition of each item after repair. If a repair is performed but the defect returns, you have grounds to request a second repair under the same warranty claim.
Once your claim is submitted, understanding what comes next helps you stay in control of the repair timeline — our warranty repair process <!–NEW PAGE NEEDED–> guide walks through builder response obligations, escalation steps, and what to do if repairs are delayed or denied.
If your builder fails to respond within the timeframe specified in your warranty agreement, or refuses to repair items that clearly qualify for coverage, you have several options: written escalation to the builder’s warranty department, contact with your state’s contractor licensing board, or consultation with a construction attorney.
Conclusion
An 11-month warranty walkthrough is one of the most valuable steps a new homeowner can take to protect their investment. Inspecting every system, documenting every defect, and submitting a complete written claim before the 12-month deadline ensures your builder remains responsible for the repairs they owe you.
The difference between a covered repair and an out-of-pocket expense often comes down to timing and documentation. Acting at month 11 gives you the time and leverage to do both correctly.

What happens if my builder refuses to repair a warranty item?
If your builder disputes or refuses a valid warranty claim, you can escalate in writing to their warranty department, file a complaint with your state’s contractor licensing board, or consult a construction attorney. Keep all documentation of your original submission and any builder responses.
Can I hire someone to help with my 11-month walkthrough?
Yes. A professional home inspector or experienced handyman can walk through your home with you, identify defects you may have missed, and help you build a complete, well-documented warranty claim before you submit it to your builder.
What defects are typically covered under a one-year builder warranty?
One-year builder warranties typically cover workmanship and materials defects including drywall imperfections, paint failures, trim and finish issues, door and window alignment, grout and caulking failures, and minor plumbing and electrical deficiencies. Structural defects and major system failures are usually covered under separate longer-term warranty tiers.
What should I do if I miss the 11-month walkthrough deadline?
If you miss the 11-month mark, submit your warranty claim in writing as soon as possible before the 12-month expiration date. Even a partial list submitted before the deadline is better than none. After the 12-month mark, most workmanship warranty coverage ends and repairs become your financial responsibility.
