What Castle Hills homeowners ask most

Is home insurance required in Castle Hills?

There is no state requirement. Mortgage contracts, HOA rules and some condo bylaws are what usually make coverage mandatory.

How does flood coverage work for a Castle Hills home?

A standard homeowners policy will not pay for flood damage, so you need a stand-alone flood policy. Castle Hills is an NFIP community, and its current flood map took effect in September 2010. In Bexar County, about 1 in 129 homes has an NFIP policy. Buy early, because NFIP coverage generally starts 30 days after purchase.

When is the best time to compare home insurance in Castle Hills?

Yearly is a good habit, plus whenever your premium jumps, you finish a remodel or you replace the roof.

Which weather risks matter for insuring a home in Castle Hills?

Overall, FEMA scores Bexar County as relatively high. Its standout hazards are hail (very high), tornadoes (very high) and inland flooding (very high). Use that list to decide where higher limits or a lower deductible are worth the premium.

Is foundation movement covered for Castle Hills homes?

Generally no. Settling and earth movement are excluded on most homeowners forms, even though drought, rated relatively moderate in Bexar County by FEMA, can move foundations. A covered water leak that damages the slab may be the exception.

What home details should I have ready for a Castle Hills quote?

Start at www.bcad.org, the Bexar appraisal district site, for size, year built and improvement records. Add your roof replacement date and any updates to complete the picture.

Is a percentage deductible a good idea in Castle Hills?

A percentage deductible is calculated on your dwelling limit; for example, 2% of a $300,000 dwelling limit is $6,000 out of pocket per wind or hail claim. A flat-dollar deductible usually costs more in premium but is easier to budget. With 242 reports of inch-plus hail in Bexar County from 2016 through 2025, it is worth pricing both options.

Is windstorm insurance through TWIA an option in Castle Hills?

No, Bexar County is not in TWIA territory. Look instead at the wind and hail deductible on your homeowners quotes, since that is where storm costs land.

Does homeowners insurance cover tornado damage in Castle Hills?

Yes, tornado damage is covered as windstorm, subject to your wind and hail deductible. NOAA records show 5 tornadoes in Bexar County from 2016 through 2025, so confirm your dwelling and loss-of-use limits would cover a full rebuild.
