What a home warranty does not cover

Overview

Start from what the product is. A home service contract prices the repair or replacement of mechanical and electrical components that fail from normal wear and tear, over a one-year term, at a premium a homeowner will renew. Nothing about that pricing model supports a roof, a foundation, a remediation project, or a loss whose cost is set by the size of the damage rather than the price of the part. The exclusion list is what keeps the product solvent, and it is drafted with more care than the grant of coverage.

The exclusions sort into six families, and each family has a different product or professional that actually addresses it. That last part is the genuinely useful piece, because "not covered" is only half an answer.

1. Structural components

Foundations, framing, load-bearing walls. These are excluded because failure is not mechanical, diagnosis is an engineering question, and the cost distribution has no ceiling a service contract could price against.

What addresses them: for an existing home, a structural or geotechnical engineer's evaluation during the inspection period, followed by a foundation contractor's scope and, where available, a transferable contractor warranty. For a new home, the builder's warranty — but note how narrow the structural tier is. Statutes and industry booklets converge on nearly identical language: actual physical damage to designated load-bearing elements, caused by failure of those elements, affecting their load-bearing function to the extent the home becomes unsafe, unsanitary or otherwise unlivable. Cosmetic cracking and settlement within building tolerance are Year 1 workmanship items, not structural ones, which is why the eleven-month callback matters so much more than the ten-year tier.

2. The building envelope

Roof covering, windows, doors, siding, gutters, flashing. Excluded for the same reason, plus one more: the envelope is exposed to weather, which is a peril rather than a wear-and-tear failure. Some contracts sell a limited roof leak add-on with a modest cap; that is a repair allowance, not roof coverage.

What addresses them: homeowners insurance for sudden physical loss from a covered peril such as wind or hail — subject to roof settlement schedules that may pay actual cash value on an older roof — plus manufacturer warranties on shingles, windows and siding, which are typically material warranties with their own registration and transfer requirements, and the installing contractor's workmanship warranty. Before closing, the tools are a roof-specific inspection, the permit record for any re-roof, and an insurance quote obtained early enough that a roof-age declination is still actionable.

3. Conditions rather than components

Mold, water damage, pest and termite activity, asbestos and lead paint. A service contract covers things that break. These are not things; they are states of the building, usually caused by something else, and their remediation cost is unbounded. Mold is near-universally excluded outright, and even builder structural warranties exclude mold, mildew, fungi and gradual deterioration from moisture.

What addresses them: different professionals for each, which is exactly why the category confuses people.

• Mold — an assessor to identify and a remediation contractor to remove, with the underlying moisture source repaired first. Homeowners policies typically cap fungi remediation at a sublimit rather than at the dwelling limit; the amount is carrier- and state-specific and sits on the declarations page.
• Water damage — homeowners insurance for sudden and accidental discharge, not for constant or repeated seepage over a period of weeks, months or years, which many carrier forms convert into a hard fourteen-day cutoff. "Sudden and accidental" refers to the onset of the loss, not the moment of discovery.
• Termites and other wood-destroying insects — a WDI inspection during the option period and a pest control operator's treatment and bond. Insurance excludes damage from insects and rodents; the warranty excludes it; the bond is the only instrument that touches it.
• Asbestos and lead paint — licensed abatement or encapsulation, and, for pre-1978 housing, the federal disclosure regime and its ten-day evaluation opportunity before the buyer is obligated to purchase.

4. Anything outside the foundation footprint

This is the most under-appreciated boundary in the entire product, and it is spatial rather than conceptual. Contract language commonly limits covered lines to those located within the perimeter of the main house foundation. That single phrase moves the sewer lateral to the street, the water service from the meter, the well and its pump, the septic tank and drain field, the irrigation system, the detached garage and the pool equipment pad all outside the base grant — available, if at all, only as priced add-ons.

What addresses them: a sewer scope during the inspection period (a general inspection does not include one), a dedicated septic inspection and pumping, a well flow and water quality test, and specific add-on coverage bought deliberately rather than assumed. For a leak in the yard, the homeowner is usually the payer of record and the excavation is the expensive half.

5. Cosmetic items

Finishes, paint, cabinetry faces, tile, trim, dents and scratches on covered equipment, and the appearance of a repair after access. Excluded because they do not affect function, and function is what the contract insures against losing.

What addresses them: negotiation inside the inspection or option period, where a cosmetic condition is a price conversation rather than a coverage one. After closing, nothing does. This is also where the access provisions land: a contract that returns an opening to a rough finish has performed, and the finish work is the owner's.

6. Consequential and secondary damage

The failed part is the contract's subject. The damage the failure caused is not. Service contracts exclude consequential damage as a class, and builder warranties exclude consequential water damage explicitly.

What addresses it: homeowners insurance, which is built for exactly this and is the reason the two products are complements rather than substitutes. The worked example is a burst supply line: the pipe is the warranty's problem, the soaked drywall and flooring are the insurer's, the opening and closing of the wall is contested by both, and the slow seepage that preceded the burst is excluded by the insurer as repeated leakage and by the administrator as a pre-existing condition or lack of maintenance. That fourth quadrant is the true gap between the products, and it is the most common real-world outcome.
