The Final Walkthrough: What to Check Before the Last Payment (Printable Checklist)
Your final payment is the only leverage you have left — release it only after four things: the punch list is complete, signed lien releases are in hand, permits are closed with final inspections passed, and warranty documents are physically delivered. “We’ll come back next week to finish up” after full payment is a sentence with a well-documented survival rate. Here’s the complete walkthrough, by trade.
The Four Gates Before the Last Check
| Gate | What “done” means | What skipping it costs |
|---|---|---|
| 1. Punch list complete | Every item from your walkthrough fixed — not “scheduled” | Unfinished work you’ve already paid for |
| 2. Lien releases signed | Final waivers from the contractor and subs/suppliers | A mechanic’s lien on your house for bills the GC never paid |
| 3. Permits closed | Final inspection passed, signed off by the building department | Open permits surface at home sale and insurance claims |
| 4. Warranties delivered | Written workmanship warranty + manufacturer registrations | ”We stand behind our work” with no paper behind it |
This is the payment-schedule endgame — the 5–10% holdback you built in at contract time exists precisely for this moment.
The Walkthrough Itself: How to Run It
- Schedule it in daylight, with the contractor present, contract and quote in hand (the itemized one)
- Walk the scope line by line — check off each contracted item physically, not from the invoice
- Operate everything: every faucet, switch, outlet, door, window, appliance the work touched — run them, don’t look at them
- Write the punch list together, date it, both sign it, set a completion date
- Photograph the finished work — your baseline if warranty disputes arise later
What to Check, by Trade
Roofing: ridge/valley lines straight; flashing at chimneys and walls sealed; attic check for daylight/stains; gutters cleared of nails (magnet sweep of the yard too); debris hauled; manufacturer warranty registered (what roofs should cost)
HVAC: system runs a full cycle in both modes; registers blow in every room; thermostat programmed and explained; old equipment hauled; permit final passed; maintenance schedule in writing (HVAC guide)
Plumbing: full-pressure hot and cold at every fixture; under-sink connections dry after 10 minutes of running; drains fast; water heater set ~120°F; shutoffs at every fixture actually turn (plumbing guide)
Electrical: every outlet tested (a $10 tester finds open grounds/reversed polarity); GFCIs trip and reset; panel directory labeled accurately; no exposed junctions; permit final passed (electrical guide)
Painting/flooring: inspect in daylight and lamplight at an angle — lap marks, thin coverage, transitions, squeaks; leftover labeled paint/materials handed over (painting, flooring)
The Lien Release: The Paper Most Homeowners Skip
A mechanic’s lien lets unpaid subs and suppliers attach your house for money the contractor owes them — even when you paid the contractor in full. The defense is boring paperwork: a final unconditional lien waiver from the GC, plus waivers from major subs/suppliers on bigger jobs (ask the GC for the list — hesitation is information). Some states have statutory waiver forms; the contractor knows them. No waivers, no final check. If you’re past that point and a lien lands anyway, start with the recovery playbook — and an attorney for the lien itself.
What If the Walkthrough Finds Problems?
Normal: a punch list of minor items with a signed completion date and the holdback intact. Not normal: pressure to release final payment “on good faith,” vanishing availability after the big check clears, or “that’s extra” for contracted items. Document each defect in writing (photos + the signed punch list), follow the demand sequence if it stalls, and remember the warranty clock: workmanship issues that surface in months 1–24 are exactly why the warranty had to be gate #4, in writing.
Frequently Asked Questions
How much should I hold back until the final walkthrough? 5–10% of the contract price, written into the payment schedule from day one. It’s not adversarial — it’s the standard structure that keeps both sides honest at the finish.
What is a lien release and do I really need one? A signed waiver proving the contractor (and subs/suppliers) have been paid and give up lien rights. Yes, you need it — homeowners who paid in full still get liened every year for the GC’s unpaid bills.
The contractor says the permit “doesn’t need a final inspection.” True? Almost never — permits exist to be closed by final inspection. An open permit blocks home sales, complicates insurance claims, and signals work that wouldn’t pass. Call the building department yourself; it’s a five-minute check.
What if I find defects after I’ve made final payment? That’s what the written workmanship warranty covers — submit defects in writing with photos. No written warranty? You’re in demand-letter territory, with far weaker footing — which is why warranty delivery is a payment gate, not a courtesy.
Should the contractor be present at the final walkthrough? Yes — it’s faster (operate-everything questions get answered live), and the jointly signed punch list becomes an enforceable document instead of your unilateral complaint.
