Frequently Asked Questions
How accurate is this storm shelter cost estimate?+
The calculator returns a 2026 installed price range based on national averages and state cost multipliers. Final quotes vary with slab condition, garage access, door upgrades, and rebate paperwork requirements. Use the range as a sanity check on dealer quotes.
Does the estimate include a state rebate?+
Yes, when the state runs an active program. The calculator subtracts the typical reimbursement (capped at the state's published maximum) to show the post-rebate net cost. Final eligibility depends on documentation and program enrollment status.
What is not included in the estimate?+
Premium door upgrades (ADA-compliant 32 inch opening), custom paint or finish, electrical pre-wire, and any slab replacement work above standard prep. These typically add $200 to $1,500 depending on scope.
