One-Year Warranty Checklist: What Inspectors Actually Find

Why timing matters for your builder warranty

You usually get one clear window to request builder repairs under the one-year warranty. Most homeowners schedule a warranty inspection around month eleven to document defects before coverage expires.

Inspectors in the DFW area commonly find foundation movement and grading problems. They also often report exterior envelope failures, plumbing and HVAC issues, electrical safety hazards, and attic insulation gaps.

A focused checklist helps you spot workmanship and performance failures before the clock runs out. This article gives a concise, inspector-backed checklist, simple documentation best practices, and prioritized next steps to present to your builder.

Most common one-year defects by category (what to watch for at home)

Worried you'll miss something important before your one-year warranty ends? Focus on a few trouble spots that inspectors in the DFW area see again and again.

Expansive clay soils and seasonal wetting and drying make some findings more likely here. Read about real-world examples and Texas-specific risks in our new-build defect stories from the field.

Structural and site issues

• Foundation and slab settlement showing as drywall cracks, uneven or cracked floor tiles, or doors and windows that stick.
• Significant cracks wider than 1/4 inch, horizontal cracks, or stair-step masonry cracks are red flags for further evaluation.
• Poor grading and downspouts discharging too close to the foundation causing water pooling near the home.
• Framing-related shifts like nail pops, trim gaps, or separations at ceiling lines that appear repeatedly in one area.

Exterior and envelope

• Improper flashing at roof-to-wall intersections that lets water enter behind siding or trim.
• Missing or failed sealant around windows and doors allowing visible gaps or water stains.
• Gaps between the foundation and concrete patios or steps where water can pool and track under the envelope.

Mechanical, plumbing, and HVAC

• Plumbing leaks at hose bibs, under sinks, or around water heaters that show stains or active dripping.
• HVAC refrigerant problems or clogged condensate drains that cause system short-cycling or water on the floor.
• Loose or disconnected ductwork producing restricted airflow and hot or cold spots in rooms.

Electrical, safety, and ventilation

• Missing or improperly installed GFCI and AFCI protection, open grounds, or loose breakers creating shock or fire risk.
• Exhaust fans or dryer vents terminating into the attic instead of outside, which can cause moisture and mold.
• Stair handrails missing or guards with gaps wider than allowed, plus improperly spaced balusters.
• Smoke and CO detectors present and placed correctly, though sensor integrity may need separate testing.

Attic and insulation

• Voids or gaps in attic insulation that show cold or hot spots inside living spaces.
• Blocked or poorly installed ventilation that leads to moisture buildup and reduced efficiency.

Prioritize foundation movement, drainage failures, and active electrical hazards for immediate attention. Document symptoms with photos, dates, and measurements so the builder can assess repairs before the warranty window closes.

Make your warranty claim stick with inspector-proof documentation

Want the builder to schedule repairs instead of arguing about what you saw? The difference is often how you document the problem. Clear, objective evidence removes guesswork and speeds agreement.

Start every item with a context photo that shows the room or exterior location, then add close-up images of the defect. Include a ruler, tape, or a common object in close-ups so the builder sees exact scale, and keep date/time consistency for the record.

What to include for every reported item

• Location: name the room, elevation, or exterior face so the builder can find it quickly.
• Symptom: use neutral, specific language that describes what you observed, for example "crack through drywall corner" rather than "looks bad."
• Supporting media: include a wide-context shot, at least one close-up, and a measurement indicator placed next to the defect.
• Reference: note any applicable code, manufacturer instruction, or tolerance if known so the claim ties to a standard.
• Recommended trade and urgency: say which contractor should evaluate the repair and whether the item needs immediate attention.
• Date/time and consistency: deliver images and notes in a consistent format so the builder sees an organized, chronological record.

Why a polished, timely report gets repairs scheduled

Neutral, standard-aligned writeups make claims harder to dispute. Reference to codes or manufacturer guidance gives the builder a clear basis for action.

A prioritized summary and clear photos let builders triage work without extra site visits. That reduces back-and-forth and raises the chance repairs get accepted and scheduled.

We recommend documenting issues at about month eleven so repairs can be requested before the warranty expires. Read more about timing and documentation in our one-year warranty inspection guide and see how pre-drywall records strengthen later claims in our pre-drywall checklist.

A professional, well-organized report delivered promptly gives you the best shot of getting repairs made under your one-year warranty.

When to act and how to prioritize repairs before your warranty ends

Noticed a problem and worried the warranty will expire before it gets fixed? We recommend scheduling your one-year warranty inspection about 30 to 60 days before the warranty date so you have breathing room to act.

That window gives time for the inspection, report delivery, and the builder to review and schedule repairs. It also lets you get specialist diagnostics or written estimates if a trade report will strengthen your claim.

Triage repairs by urgency

Start by separating immediate safety and structural concerns from routine items. Some findings are red flags that need urgent evaluation and documentation.

• Urgent: address safety and major structure first. Signs include progressively widening cracks, doors or windows that get harder to operate, floors sloping more than about 1/4 inch over 10 feet, and any horizontal foundation cracking.
• High priority: recurring water intrusion, persistent HVAC failures, and electrical hazards that could cause damage or safety risks if left unresolved.
• Routine: cosmetic issues, minor sealant cracks, and normal settling symptoms you can monitor or handle as homeowner maintenance.

Call specialists when the general inspection flags a system that needs deeper diagnostics. Specialized systems like septic, private wells, pools and spas, irrigation, and detailed HVAC ductwork usually need trade testing and written reports.

• Septic and wells should be evaluated by licensed technicians when performance problems or leaks appear.
• Pools and spas need a pool specialist for pumps, heaters, and underground plumbing issues.
• Call an HVAC diagnostician if you see restricted airflow, repeated refrigerant problems, or strange odors coming from ducts.

Use estimated repair costs to set priorities

Estimated cost ranges help you decide which claims to press before the warranty ends. Homeowners should prioritize high-cost or complex items that the builder is contractually more likely to repair.

• Minor plumbing repairs usually run $175 to $400, while main-line clearing is typically $250 to $300.
• HVAC equipment replacement is expensive, with furnace work around $1,800 to $3,000 and air conditioning about $1,500 to $2,000 per ton.
• Electrical panel upgrades often fall in the $1,200 to $2,200 range, so prioritize these if they pose safety or capacity problems.

Remember that builder warranties commonly exclude routine homeowner maintenance, cosmetic issues, and damage from owner modifications. Document and submit prioritized, well‑organized findings early so the builder can respond while the warranty still applies.

Lock in builder repairs before the one‑year window closes

Schedule your one-year warranty inspection about 30 to 60 days before the warranty expires. That gives time for the inspection, the report, and the builder to review and schedule repairs.

Focus on DFW-prone trouble spots: foundation and drainage, the exterior envelope, and mechanical systems. Document each item with a wide context photo, close-ups, measurements, and neutral descriptions so the builder can act.

Escalate red-flag findings right away. Progressive cracks, active leaks, or electrical hazards need urgent attention and clear, inspector-backed documentation.
