The Ultimate New Construction Walkthrough Checklist

Why it matters

The final walkthrough—often called the Pre-Settlement Demonstration—is your last chance to identify defects before the builder’s responsibility shifts to a standard warranty. Catching a major flaw now, such as a missing insulation baffle or a poorly graded yard, can save you thousands of dollars in out-of-pocket repairs and months of scheduling headaches once you have moved in.

While new homes are inspected by the city, municipal inspectors only check for code compliance, not quality of finish or cosmetic perfection. This walkthrough is the bridge between "safe to inhabit" and "built as promised." By documenting issues on a formal "punch list," you create a paper trail that holds the developer accountable.

How often

For a new construction home, the walkthrough process generally happens in two stages:

1. The Pre-Settlement Walkthrough: Occurs 7 to 14 days before closing. This is where you create the primary punch list.
2. The Final Verification: Occurs on the day of closing. This is a quick check (usually 30–60 minutes) to ensure items from the first list were actually repaired.

What you need

Most builders will provide a representative to guide you, but you should bring your own toolkit to verify performance:

• A Phone Charger: To test every electrical outlet.
• Flashlight: To inspect dark corners of the attic, crawlspace, or back of cabinets.
• Blue Painter’s Tape: To mark scuffs or defects directly on surfaces without damaging finishes.
• A Notebook or Tablet: To record the official punch list.
• The Original Specs/Contract: To verify that the finishes (granite vs. quartz, etc.) match what you paid for.
• A Small Level: To check for uneven flooring or shelves.

Step-by-step walkthrough

1. The Exterior Perimeter

Start outside and work your way in. This ensures you aren't rushing at the end when you're tired.

• Grading: Confirm the soil slopes away from the foundation. Ensure there are no "swales" or low spots where water will pool against the house.
• Siding and Trim: Look for gaps in caulking, mismatched paint, or loose siding panels.
• Roof and Gutters: From the ground, use your eyes or a camera zoom to check for missing shingles or gutters that are not properly pitched toward the downspouts.
• Windows and Screens: Ensure all screens are present and that window frames are not scratched or cracked.

2. Systems and Mechanicals

The "guts" of the house are the most expensive to fix later.

• HVAC: Turn the thermostat to Heat and wait for air to blow, then switch to Cool. Ensure the air handler isn't making unusual banging noises.
• Plumbing: Flush every toilet. Run every faucet for 2 minutes to check for leaks under the sink and to ensure hot water is reaching the fixture. Fill the bathtubs and let them drain simultaneously to check the drainage speed.
• Electrical: Plug your phone charger (or a circuit tester) into every single outlet. Test all light switches and ceiling fans.

3. Kitchen and Appliances

Appliances are often installed by third-party contractors and are high-risk for cosmetic damage.

• Appliances: Run a short cycle on the dishwasher. Turn on every burner on the stove. Check the oven light and the ice maker.
• Cabinetry: Open and close every drawer and door. Look for "hinge rub" or misaligned doors.
• Countertops: Run your hand along the seams. They should be smooth and the sealant should be uniform. Look for chips or cracks.

4. Interior Finishes

The bulk of your blue tape will likely be used here.

• Flooring: Look for "hollow" spots in tile or excessive creaking in hardwood. Check for gaps between the floor and the baseboards.
• Paint and Drywall: View walls at an angle against the light to find "nail pops" or uneven sanding. Use your blue tape to mark any scuffs.
• Doors: Open and close every door. They should stay in place (no "ghost swinging") and latch smoothly without forcing.

5. The Attic and Garage

Don't skip the "dirty" areas.

• Insulation: Ensure insulation is evenly distributed and not covering soffit vents.
• Garage Door: Test the auto-reverse safety feature by placing an object in the path of the sensor.

Safety

• Watch the Stairs: Many new builds may not have the final floor finishes or grip tape on stairs during the walkthrough. Use caution.
• Electrical Safety: If you see any exposed wiring or "open" junction boxes, do not touch them. Point them out to the builder representative immediately.
• Ladders: If you choose to look in the attic, ensure the pull-down ladder is fully secured before climbing.

When to Call a Pro

Even the most diligent homeowner can miss structural or system-level issues. You should hire a third-party home inspector to perform a "Phase 3" or Pre-Settlement inspection before your walkthrough.

Call a pro if:

• You are uncomfortable climbing into attics or crawlspaces.
• You want a thermal imaging scan to check for missing insulation behind walls.
• The builder is being dismissive of serious concerns like foundation cracks or damp basement walls.

Cost

• The Walkthrough: $0 (This is included in your home purchase).
• Third-Party Inspection: $300–$600. While optional, it is the best insurance policy you can buy for a new home.
• Blue Tape and Supplies: Under $20.

Post-Walkthrough: The 11-Month Anniversary

Most builders offer a 1-year "labor and materials" warranty. Mark your calendar for month 11. This is when you should do a second, smaller walkthrough to catch any "settling" issues—like drywall cracks or nail pops—that appeared as the house shifted over its first year of seasons. Submit these as a final warranty claim before the 12-month mark.
