First Winter New Home Condensation Checklist
Check condensation in your new home’s first winter: locate the moisture, learn ventilation controls, keep a useful log, and know when to call the builder.
A clearer view of housing.
Check new home warranty notice deadlines, coverage dates and delivery rules. Confirm who must receive your claim and what proof to keep.
A photo may document a defect without satisfying your warranty’s notice requirements. New home warranty notice deadlines depend on the warranty issued for your home, the affected component and applicable state law. Confirm the recipient, delivery method and deadline even if an inspection or repair is already scheduled.
Use this checklist after closing, whether you own the home, advise the buyer or handle builder customer care.
Obtain the warranty certificate, complete booklet, state addenda and purchase agreement. Record the effective date and the provision that establishes it. Do not substitute the inspection date or assume move-in controls.
New Jersey’s Homeowner’s Booklet, revised September 2025, for example, defines the warranty date as first owner occupation or settlement, whichever is earlier. That definition is specific to New Jersey.
If the documents conflict, request a written correction promptly. Keep the earlier date on your working calendar while you resolve the discrepancy.
The FTC’s July 2005 new-home warranty guide, preserved by GovInfo, describes common coverage patterns, not guaranteed terms:
| Coverage category | Pattern described by the FTC | What to verify |
|---|---|---|
| Workmanship and materials | Often one year | Covered finishes, installation standards and exclusions |
| Heating, ventilation, air conditioning, plumbing and electrical systems | Generally two years | Which equipment, piping, wiring or other components qualify |
| Major structural defects | Some builders provide up to ten years | The definition and severity threshold for a qualifying defect |
For each issue, record the coverage expiration and any separate notice deadline. A longer structural term does not necessarily preserve coverage for an ordinary finish defect. Manufacturer warranties may require a separate claim process.
Telling the site superintendent may not satisfy the notice clause. Check whether that person is an authorized recipient and whether your communication meets the warranty’s requirements.
Record the recipient, address, delivery method and exact timing language. Distinguish a deadline to send or postmark notice from a deadline for receipt. If a portal is permitted, save the submission and confirmation; if another method is required, use it.
RWC’s sample warranty, revised March 2024, shows why separate notices matter. For first- and second-year defects, it requires written notice to the builder during coverage. That notice neither notifies RWC nor extends coverage. If a defect remains unresolved after a reasonable time, the sample directs owners to notify RWC’s Warranty Resolution Department by either method:
The deadline to email or postmark that notice is 30 days after the applicable coverage period ends; that interval adds no coverage. The sample excludes normal wear and damage from neglected maintenance. Confirm the terms and contacts in your issued booklet and addenda, which may differ.
Build a claim file that shows what you reported and how you delivered it:
The FTC recommends a written repair request even when an urgent-request hotline exists, along with records of conversations and correspondence.
Before arranging an inspection or repair, check authorization requirements and who pays. Keep invoices and maintenance records, and follow the warranty’s emergency procedures when damage needs immediate attention.
An eleven-month inspection can help organize findings before some first-year coverage expires. Its timing is a scheduling choice, not a universal legal deadline. Report known problems as the warranty requires instead of saving them for that appointment.
Do not assume an inspection booking, open service ticket or promised repair suspends another deadline. For example, 2-10’s November 2023 booklet, section VII.B, says repairs do not extend warranty terms.
Ask for written confirmation of which defects were accepted and what remains unresolved. Continue using the original notice and dispute deadlines unless a change satisfies your warranty’s amendment requirements; a service email or repair acknowledgment alone may not do so. For example, RWC’s sample warranty, section II.D.5, requires a formal written instrument signed by the owner, builder and administrator to amend its terms. Continue tracking deadlines while repairs are pending.
Review contractual warranty procedures separately from state-law remedies for construction defects. 2-10’s booklet, section X.C, expressly says its coverage term does not extend applicable legal filing deadlines.
Choosing one process can also affect access to another. New Jersey’s official consumer guidance explains its election-of-remedy rule: filing a formal warranty claim can bar other remedies for the same claim, and choosing litigation can bar the warranty route. This rule is specific to New Jersey.
Consult a local construction-defect attorney when a deadline is disputed or you must choose between warranty proceedings and litigation.
Before treating notice as complete, make sure you can produce the governing clause, defect list and delivery proof, with the next deadline on your calendar. For related guidance and reporting, see new-home ownership responsibilities, new-construction coverage and builder operations and obligations.
It depends on the warranty’s authorized recipient and delivery requirements. Submit the defect through the required channel and retain proof, even if the superintendent has already seen it.
Do not assume it does. An appointment or report does not by itself establish that the required claim notice reached the right recipient on time.
Follow the booklet’s required form and attachment instructions. Identify the home and warranty, describe each defect and its discovery date, and preserve the complete submission with delivery evidence.
Check the administrator’s notice deadline before agreeing to wait. Ask for written acknowledgment of unresolved defects and follow the required escalation procedure while the repair remains pending.
