Closing Day and Beyond: Warranties, Punch Lists, and Your First Year in a New Build (Part 7 of 7: The Complete New Construction Buyer's Guide)

After months of watching a lot turn into a framed structure and then into a finished home, closing day can feel like the finish line. It is not. Closing day starts a warranty clock with specific coverage periods, specific deadlines, and specific things a new homeowner needs to track over the following months and years. This is Part 7, the final part of the Complete New Construction Buyer's Guide from Donnell Williams Jr. and DMV Prime Properties, and it covers what happens after you get the keys.

‍

What does a new construction home warranty typically cover? Most builders in the DMV and nationally follow what the industry calls a 1-2-10 warranty structure. Donnell Williams Jr. of DMV Prime Properties explains that this typically means one year of coverage for workmanship and materials, two years of coverage for major mechanical systems like plumbing, electrical, and HVAC, and ten years of coverage for major structural components like the foundation and load-bearing elements. Coverage details vary by builder, so confirming the exact terms in writing before closing is essential, not something to assume based on industry norms alone. DMV Prime Properties walks buyers through their specific builder's warranty documentation before closing, and donnellwilliams.com covers what to track during each coverage period.

Understanding the 1-2-10 Warranty Structure

Year one: workmanship and materials. This is the broadest coverage period and the one most likely to be used, since small workmanship issues, a door that does not close quite right, a fixture installed slightly off, paint touch-ups needed after settling, tend to surface during the first year as a new home gets used daily for the first time. Builders frequently schedule a formal service review near the end of this first year specifically so homeowners can flag anything remaining before this portion of coverage ends.

‍

Years one and two: major systems. Plumbing, electrical, heating, cooling, and ventilating systems are typically covered for two years against defects caused by non-compliance with the builder's construction standards, separate from any manufacturer warranty on individual appliances. Once this coverage ends at the two-year mark, sometimes called the "year-two cliff," homeowners are relying entirely on appliance manufacturer warranties and their own homeowners insurance for anything mechanical that fails.

‍

Years one through ten: structural coverage. The longest and narrowest coverage period applies specifically to major structural defects affecting the foundation, load-bearing walls, and other elements critical to the home's structural integrity. Structural claims are less common than workmanship or system issues, but this coverage provides meaningful long-term protection since structural repairs, if ever needed, are typically the most expensive category of repair a homeowner could face.

The Punch List: Your Last Chance for Builder-Paid Fixes

The homeowner orientation walkthrough, typically scheduled just before or at closing, is where you and the builder jointly document a punch list, items that do not yet meet the standard the contract specifies and that the builder is expected to correct before or shortly after closing. This walkthrough deserves real time and attention, not a quick fifteen-minute pass through the home. Buyers who bring a trained eye, either their own agent or an independent inspector, to this final walkthrough consistently catch more than buyers who walk through alone. One documented comparison found an independent inspector catching dozens of legitimate issues, including a missing vapor barrier and improperly wired outlets, while an unassisted buyer walkthrough caught only cosmetic items and missed a real plumbing defect in the process.

‍

A responsive builder typically addresses punch list items within a matter of days to a couple of weeks after the walkthrough. Get every punch list item in writing, with a specific timeline for completion, and follow up in writing rather than relying on verbal assurances if anything remains outstanding after your agreed timeline passes.

Filing a Warranty Claim After Closing

If something comes up after you have moved in, understand your builder's specific claims process before you need it. Most builders follow a similar general structure: document the issue with photos, video, and a written description including when you first noticed it; determine whether it is genuinely a construction defect covered by the warranty versus normal wear or something outside the builder's responsibility; submit the claim through the builder's official channel, typically an email or web form rather than a phone call alone, since a documented submission is far easier to track than a verbal report; and expect the builder to schedule an inspection, often within one to three weeks for a non-emergency issue.

‍

It is worth noting explicitly that a builder's warranty does not cover storm or weather damage, that is what homeowners insurance is for. Confusing the two is a common first-year mistake, and knowing the distinction ahead of time avoids a frustrating and unnecessary denied claim.

Should You Buy a Home Warranty on Top of the Builder's Coverage?

An additional, separately purchased home warranty is rarely worth adding during years one and two, since it would largely duplicate coverage the builder and appliance manufacturers already provide. The more useful window to consider one is typically years two through five, once the builder's systems coverage has expired and appliance warranties have run out, but before the home is old enough that a warranty provider considers it a higher-risk property. If you do consider one, look for a provider without age restrictions or exclusions on systems installed before a certain year, and purchase it before your builder coverage actually lapses, since most home warranty coverage begins from a clean, currently functioning baseline rather than covering a problem that already exists.

How This Applies Across the DMV

Washington DC: DC's consumer protection framework may affect specific warranty disclosure requirements, so DC buyers should confirm their builder's warranty documentation meets any applicable local disclosure standards before closing.

‍

Maryland: Builders active in Prince George's County and at National Harbor, where Donnell Williams Jr. has closed 184 deals from 2024 through June 2026, generally follow the standard 1-2-10 structure, though specific exclusions and claims processes vary by builder and are worth confirming in writing before closing. Learn more on the National Harbor page at donnellwilliams.com.

‍

Northern Virginia: With builders like Toll Brothers, Van Metre Homes, NVHomes, and CarrHomes active across Loudoun, Prince William, and Fairfax, warranty administration sometimes runs through a third-party warranty company the builder has enrolled the home with, which can affect how a claim is filed and who to contact first.

Frequently Asked Questions

How long is a typical new construction warranty in the DMV? Most DMV builders follow the industry-standard 1-2-10 structure: one year for workmanship and materials, two years for major systems, and ten years for structural components, though exact terms vary by builder.

‍

What is the difference between a builder warranty and homeowners insurance? A builder warranty covers defects in construction, workmanship, and materials. Homeowners insurance covers accidental damage from events like storms, fire, or water intrusion unrelated to a construction defect. They are not interchangeable.

‍

Should I bring my agent to the final walkthrough? Yes. A trained eye at the homeowner orientation walkthrough consistently catches more legitimate punch list items than an unassisted buyer walkthrough, and having your agent present adds documentation and follow-up support if the builder is slow to complete repairs.

‍

What happens if the builder does not fix a punch list item? Follow up in writing, referencing your original documented walkthrough list and any timeline the builder committed to. If a builder consistently fails to honor warranty obligations, your buyer's agent or, if needed, a real estate attorney can advise on next steps specific to your contract and jurisdiction.

A First-Year Checklist for New Homeowners

The first twelve months in a new build are worth approaching with a bit of structure, since this is the window where your broadest warranty coverage is active and where a new home reveals the most about how it actually performs day to day.

‍

Track seasonal performance. A new home has not yet been through a full year of weather in the DMV's specific climate, humid summers, cold winters, and everything in between. Note how the HVAC system performs during the first real heat wave and the first hard freeze, since these are exactly the conditions that reveal whether systems were installed and balanced correctly.

‍

Watch for settling. Small drywall cracks near door frames or window corners, and minor gaps where trim meets wall, are common as a new home settles during its first year and are typically covered under the workmanship portion of the warranty if reported within the coverage window. Document these as they appear rather than waiting until the one-year mark to report everything at once.

‍

Schedule the builder's year-end service review. Many builders proactively schedule this, but if yours does not, request it. This is your structured opportunity to have every remaining first-year item addressed before workmanship coverage lapses.

‍

Keep all documentation in one place. Your original punch list, any warranty claims filed, the builder's warranty booklet, and appliance manufacturer warranty cards should live together, physically or digitally, so nothing gets lost if an issue arises down the road.

‍

Understand what falls to you versus the builder. Routine maintenance, changing HVAC filters, cleaning gutters, resealing exterior joints as recommended, is the homeowner's responsibility from day one and is not a warranty issue if neglect contributes to a later problem. Knowing this distinction early prevents a frustrating warranty claim denial.
