Buying a new home is exciting — until you discover that the warranty period is your limited window to get the builder to fix construction defects. Too many homeowners wait until month 10 or 11, then rush around trying to document everything at once.
After inspecting many new builds and reviewing warranty claims, here’s the smart way to handle your new-home warranty walk.
Why Timing Matters
Builders typically offer a one-year warranty on workmanship and materials. Some items (like structural elements) have longer coverage, but most everyday issues need to be reported within that first year.
The sweet spot for your big walkthrough is around months 6–9. By then the house has gone through a full season of weather changes, but you still have time to get items addressed.
The New-Home Warranty Walk Checklist
Exterior and Structure:
Check foundation for new cracks or settling
Walk the roofline (from ground) for shingle issues
Test all exterior doors and windows for smooth operation
Look at grading and drainage after rains
Check siding, trim, and paint for separation or cracks
Interior Systems:
Test every electrical outlet and light switch
Run all faucets and check for proper drainage
Flush every toilet and listen for unusual sounds
Test HVAC system in both heating and cooling modes
Check for drywall cracks at corners and ceilings
Kitchen and Baths:
Look under sinks for any leaks after running water
Test appliances that came with the home
Check cabinet doors and drawers for alignment
Inspect grout and caulk in wet areas
Attic and Mechanicals:
Check insulation coverage and ventilation
Look for any roof leaks or stains
Verify water heater and furnace operation
Note any unusual noises or smells
Documentation Tips:
Take dated photos of everything
Create a clear list with photos and descriptions
Submit items in writing through the builder’s process
Keep copies of all communications
Common New Construction Issues I See
Improperly installed flashing around windows and roofs
HVAC systems not balanced properly
Plumbing lines with poor support
Drywall finishing issues that become obvious after humidity changes
Grading and drainage problems that only appear after heavy rain
Catching these early makes them much easier for the builder to address.
My Personal Approach With Our Family
When we bought our current home (not new, but the principle is similar), we did seasonal walks from day one. For truly new builds, I recommend doing a 30-day, 6-month, and 10-month walkthrough.
Noah loves the “treasure hunt” aspect of finding cracks or loose items. Maya just enjoys opening every cabinet. It turns a necessary task into family time.
A ten-minute check today saves a ten-thousand-dollar call tomorrow. In new construction, consistent checks during the warranty period can save you significantly more.
Don’t wait until the warranty is almost expired. Start your documentation early and stay on top of it. Builders are much more responsive when you have clear, well-documented issues with photos and dates.
If you’re in a new home right now, schedule your next warranty walk this month. Walk slowly, test everything, and document thoroughly.
Your future self will be very glad you did.
