New Construction Punch List: The Final Walkthrough Checklist for Colorado Buyers

Your final walkthrough, often called the "blue tape walk" or "punch list walk," is the last time the builder will be motivated to fix things before you own the house. After closing, every fix goes through the warranty process, which is slower and easier for a builder to push back on.

Most buyers go into this walkthrough excited and rushed, and they miss things. This is the checklist I use with my clients in Northern Colorado, including a few items specific to building here.

If you haven't read it yet, start with our new construction inspections page. The punch list is the last step in a process that ideally includes a pre-drywall and a final inspection.

What a Punch List Is (and Isn't)

A punch list is the written list of items the builder agrees to fix or finish before closing, or by a set date after closing. It covers cosmetic and functional problems: paint touch-ups, a door that doesn't latch, a missing outlet cover, a scratched counter.

It is not a replacement for a professional inspection. Your walkthrough catches what you can see. A licensed inspector catches what you can't: the electrical panel, roof, attic insulation, HVAC operation, and grading. Get the inspection done a few days before your walkthrough so its findings go on the same punch list.

Before the Walkthrough

• Schedule it in daylight, and leave at least two hours. Rushing is the most common mistake.
• Ask for the builder's walkthrough form in advance so you know what they track.
• Bring: blue painter's tape, a phone charger (to test outlets), a flashlight, a notepad, and your inspection report.
• Have the utilities on so you can test every system.
• Bring your agent. A second set of eyes, and someone who isn't emotionally attached to the house, catches more.

Exterior Checklist

• Grading and drainage: soil slopes away from the foundation on all sides; no low spots against the house
• Downspouts: extensions in place and draining away from the foundation
• Concrete: driveway, walks, and patio free of large cracks, chips, or pooling areas
• Siding and trim: no gaps, loose pieces, missing caulk, or paint misses
• Roof (from the ground): no missing shingles or visible damage
• Windows: screens installed, no cracked glass, seals intact
• Exterior doors: close, latch, and lock smoothly; weatherstripping intact
• Garage door: opener works, auto-reverse safety sensor works, remotes provided
• Hose bibs and exterior outlets: working, outlets GFCI-protected
• Landscaping: completed per contract, or a written completion date if it's been deferred

Interior Checklist

Walls, ceilings, and floors

• Drywall: look at each wall with a flashlight held flat against it to spot nail pops, seams, and dents
• Paint: consistent coverage, no drips, clean lines at ceilings and trim
• Flooring: no scratches, gaps, lifting edges, or squeaks
• Carpet: seams tight and edges secure

Doors, windows, and cabinets

• Every interior door opens, closes, and latches without sticking
• Every window opens, closes, and locks
• Cabinet doors and drawers aligned and closing evenly
• Countertops: no chips, scratches, or unsealed seams

Kitchen and appliances

• Every appliance runs: range, oven, microwave, dishwasher, disposal, refrigerator if included
• Range hood vents properly
• Sink drains quickly with no leaks underneath

Bathrooms

• Run every faucet and shower; check hot water reaches each one
• Look under every sink for leaks
• Flush every toilet and confirm it refills and stops
• Exhaust fans run
• Caulk complete at tubs, showers, and counters
• GFCI outlets trip and reset

Electrical and mechanical

• Test every outlet (that's what the phone charger is for)
• Every light fixture and switch works
• Smoke and carbon monoxide detectors installed and working
• Furnace and AC both run (test heat even in summer)
• Water heater working, with the right temperature setting
• Electrical panel labeled

Colorado-Specific Items to Ask About

Building on the Front Range comes with a few things buyers from other states don't always think about:

• Radon: Colorado has high radon potential. Ask whether the home has a radon mitigation system (passive or active) and whether a post-closing radon test is recommended.
• Expansive soils: Many Front Range areas have clay soils that swell and shrink. That's why grading and downspouts matter so much. Ask for the foundation's soils report and engineering letter.
• Winter closings: if you close in winter, exterior concrete, landscaping, and sometimes paint get deferred. Get every deferred item in writing with a completion date.
• Sprinklers: if the home has an irrigation system, ask who handles the first fall blowout and spring startup.

How to Document Everything

1. Mark each issue with blue tape and photograph it, with the room visible.
2. Write it on the builder's punch list form, not just your own notes.
3. Get a signed copy before you leave, with the builder's agreed completion dates.
4. Do a re-walk before closing to confirm items were fixed. Anything not fixed should be documented in writing before you close.

After Closing: Don't Skip the 11-Month Inspection

Most production builders give you one year of workmanship coverage. Book a second inspection around month 11, before that coverage ends, and submit everything it finds in one warranty request. Warranty terms vary by builder, and some are shorter in Colorado than national marketing suggests, so read your actual warranty document. More in our new construction warranty guide.

Want a Second Set of Eyes?

Walking through new construction with buyers is a big part of what I do. I've seen what builders tend to miss and what they push back on. If you're buying new in Northern Colorado, get in touch before your walkthrough is scheduled.

Frequently Asked Questions

When does the final walkthrough happen on new construction? Usually a few days to a week before closing, after the builder finishes construction. Schedule your independent inspection a few days earlier so its findings make the punch list.

Can I refuse to close if punch list items aren't done? That depends on your contract. Most builder contracts don't let you delay closing over cosmetic items, which is why getting every item, and its completion date, in writing before closing matters.

Do I need a home inspection if I'm doing a walkthrough? Yes. The walkthrough catches what you can see. An inspector checks the roof, attic, electrical, mechanical systems, and grading, which most buyers can't evaluate themselves.

What should I bring to a new construction walkthrough? Blue painter's tape, a phone charger to test outlets, a flashlight, your inspection report, and your agent.
