A contractor project is only truly finished when you've walked through every detail and signed off on completion. Skipping this step leaves you vulnerable to punch-list items, incomplete work, and disputes over payment. This guide walks you through the final inspection process so you can accept your project with confidence.
What Is a Final Walkthrough?
A final walkthrough is a systematic review of all completed work, conducted with your contractor present, before you pay the final invoice or release retainage. This isn't a casual stroll—it's a documented inspection where you verify that every element matches your contract, passes local code requirements, and meets your quality standards.
Most residential and light commercial remodels schedule the walkthrough 1–2 days before you plan to release final payment. If the contractor has already left the job site, you'll either need to arrange a time for them to return or request written documentation of completion.
Prepare Your Inspection Materials
Before the walkthrough, gather the documents you'll need:
- Your original contract and any change orders
- Permit documents and code compliance certificates
- Product specification sheets (for appliances, flooring, fixtures)
- Photos from the project's start
- A notebook or tablet to record notes and photos of any deficiencies
Set aside at least 1–2 hours for the inspection. Walking quickly through a major addition or kitchen remodel will cause you to miss details. Many customers find it helpful to bring a trusted friend or family member—a second set of eyes catches things you might overlook.
Key Areas to Inspect
Structural and Framing Work
Check that walls are plumb (use a 4-foot level), floors are level, and doors and windows open smoothly without sticking. Look for gaps between walls and ceilings, uneven baselines, or visible nail pops. In additions, verify that the new structure is properly tied into the existing home and that any exposed framing is finished or sealed as specified.
Finishes and Paint
Inspect paint for drips, uneven coverage, or missed spots. Check that caulking is smooth and consistent, particularly where different materials meet. Look for touch-ups around outlets, light switches, and trim work. Run your hand along surfaces to feel for bumps or rough spots that indicate unfinished sanding.
Plumbing and Electrical
Turn on all faucets and check for leaks under sinks and at shutoff valves. Run water through drains to ensure they flow freely. Test every switch, outlet, and light fixture. Verify that GFCI outlets are installed in required areas (kitchens, bathrooms, laundry rooms). Ask your contractor for documentation that electrical work passed inspection by the local building department.
Flooring and Tile
Walk the perimeter of each room checking for gaps between flooring and baseboards. Press on tile to feel for hollow spots or movement. Check grout lines for consistent width and color. Look for any cuts or chips on exposed edges.
Doors, Hardware, and Cabinets
Open and close every door to ensure proper operation. Check that hinges are tight and doors don't sag. Test cabinet doors and drawers for smooth operation and proper alignment. Verify all hardware (hinges, knobs, pulls) matches what was specified in your contract.
Document Any Deficiencies
If you spot incomplete or substandard work, don't accept it verbally—create a written punch list. Be specific: "Kitchen faucet leaks at base" is actionable; "plumbing doesn't look right" isn't. Take photos and note the room, item, and issue. A typical punch list for a kitchen or bathroom remodel might include 5–15 items, while larger additions can have 20+.
Your contractor should return to complete punch-list items within 7–14 days at no extra cost (assuming they fall within the contract scope). Hold back 10–15% of final payment as retainage until all punch-list work is finished and you've done a follow-up inspection.
Getting Official Approval
Before you fully release payment, confirm that the contractor has obtained a Certificate of Occupancy or a final inspection sign-off from your local building department (if permits were required). This protects you legally and ensures the work meets code.
Frequently Asked Questions
Q: How much should I hold back in retainage if the punch list is small? Hold back at least 5–10% of the final invoice amount, even for minor issues. This ensures the contractor returns to complete remaining work before you release the full payment.
Q: What if the contractor disputes items on my punch list? Review your contract and change orders to determine whether disputed items fall within the agreed scope. If disagreement persists, consult your contract's dispute resolution clause or contact a mediator.
Q: Can I use Mercoly to compare contractors before hiring, or only after a project fails? You can use Mercoly to research and compare trusted general contracting providers in your area before you hire, so you select a contractor with a track record of thorough final inspections and quality completion.
Q: How long do I keep warranty documentation after final walkthrough? Keep all warranties, certificates, and manuals for at least 5–10 years. Many building components carry warranties that extend beyond your initial project completion.
