Most people don’t think about insulation until their house feels a bit chillier than it should. Insulation can last up to 100 years, but pests like mice, rats and squirrels or a disaster like flooding can damage insulation. Replacement can be a costly hit to your budget. Unfortunately, you probably won’t be able to file a home warranty claim to help you with the costs. Here’s what you need to know.
Home warranty companies don’t cover insulation.

Home warranty companies typically exclude insulation because it is considered a structural part of the house, not a system or appliance. Most home warranty plans are designed to cover the repair or replacement of mechanical systems and appliances that have moving parts or electrical functions.
The cost of a home warranty plan is meant to cover appliances and systems like:
- Dishwashers
- Plumbing
- Refrigerators
- HVAC systems
- Ovens, cooktops and ranges
- Built-in microwave ovens
- Ductwork
- Electrical
- Washer and dryer
- Garbage disposals
Insulation is considered a structural component of your home, like your foundation or the studs in your wall. Structural components aren’t typically part of home warranty coverage.
What to do if your home warranty doesn’t cover insulation
Even if your home warranty doesn’t cover insulation, you may still be covered. Insulation could be covered under your builders warranty if your home is new. Or, if the damage was caused by an “act of God” like a fire or flood, your home insurance may cover the replacement of your insulation.
There are some situations where insulation damage may be addressed indirectly. If a covered system, like plumbing or HVAC, fails and causes damage to your insulation, the warranty provider might pay for insulation repair or replacement as part of fixing the covered system.
For example:
- Burst pipe: If a covered plumbing failure soaks your insulation, the warranty may cover insulation replacement as part of the plumbing repair.
- HVAC malfunction: If a covered HVAC system leaks and damages insulation in the attic or walls, the warranty could cover insulation repair when fixing the HVAC issue.
Coverage for these situations varies by provider and policy. Always review your home warranty contract or contact your provider to understand how incidental insulation damage might be handled during a covered repair.
FAQ
What does a home typically warranty cover?
Home warranties usually cover large appliances, built-in microwaves, water heaters and systems like HVACs, plumbing, ductwork, pool heaters and well pumps. Some plans also cover additional items like pest control, septic systems, central vacuums, sump pumps and more.
Do home warranties cover water damage to insulation?
While most home warranties usually do not cover water damage, many of them include coverage for plumbing issues that could lead to water damage.
What does a home warranty not cover?
Home warranties typically don’t cover structural elements of the home, like the foundation, beams or walls.
What are common signs my insulation needs attention?
You may need to inspect or upgrade your insulation if you notice uneven temperatures in your home, drafts or higher-than-normal energy bills. Visible problems like dampness, mold or pest infestations near insulation also suggest it may need repair or replacement.
Bottom line
Home warranties typically do not cover insulation, as it is considered part of the home's structure rather than a system or appliance. However, your builders or homeowners insurance may be able to help you with replacing damaged or old insulation.
