We install tornado safe rooms and storm shelters across the St. Louis metro — in basements, garages, utility rooms, new homes and homes being rebuilt — built to FEMA P-361 and ICC 500 criteria for a 250 mph design tornado. Many St. Louis homes have basements, and a basement is the right place to go without a shelter. It isn't a tested one. On May 16, 2025, an EF3 with 152 mph winds crossed Clayton, Forest Park and north St. Louis into Granite City; the National Weather Service later found it 1.8 miles wide. We help St. Louis households turn "the best place we've got" into a room built for the job.

Start with your house
I have a basement. A safe room in the basement keeps you below ground and adds tested protection against debris and collapse. First read do you need a shelter if you have a basement? → Basement safe rooms
I'm on a slab. Common in many newer homes and villas. An above-ground steel safe room in the garage or a utility room — or, where the ground stays dry, an in-ground unit in the garage floor. → Above-ground safe rooms · Garage storm shelters
I'm building or rebuilding. The cheapest time to add a safe room is before the walls close up — including homes being rebuilt after the 2025 tornado. → New construction and rebuild safe rooms
Also: underground storm shelters — and when they're the wrong choice here — and community storm shelters for mobile-home parks, churches, employers and HOAs.
Built to the standard, not to a sales line
- FEMA P-361 and ICC 500. The criteria and standard that define a tested safe room: a 250 mph design tornado, debris-impact testing, anchorage, ventilation and floor area per person.
- No "FEMA approved." FEMA doesn't approve or certify products. We give you the test documentation and door label instead.
- The slab matters. Every steel unit is anchored to concrete that meets its manufacturer's specification. We check yours before we quote.
The truth about money and permits
Money. Missouri's State Emergency Management Agency says the state offers residents no grant, rebate or financial assistance for residential safe rooms. Federal mitigation money goes to community and school safe rooms through local governments. We'd rather tell you that up front. See grants, rebates and financing.
Permits. In unincorporated St. Charles County, every storm shelter needs a building permit. Elsewhere, it depends on your city. See permits.
What it costs
A national manufacturer's St. Louis list prices above-ground steel units from $3,995 to $8,985 and below-ground units from $7,315 to $9,775 (2024), slab not included. HomeGuide's national guide (written February 2024) puts installed safe rooms at $4,500–$14,000. Those numbers come from published sources, not from us; a written quote from us covers the unit, slab, delivery, anchoring and permit. Line-by-line detail is in the cost guide; a quick range is in the instant quote.
From first message to finished shelter
- Describe your house on the quote form: basement or slab, where you'd like it, how many people.
- Site visit. Our installation crew checks the space, the slab or floor, the stairs or garage door, and water.
- Written quote. Type, size and occupancy, the standard, slab plan, anchoring, delivery, permit and schedule.
- Permit and install. Steel units install in hours once the slab is ready; built-in rooms take longer.
- Handover. Documentation, door label, and a walk-through of getting everyone inside.
Our installation crew is a Missouri construction contractor that installs storm shelters as a dedicated part of its business.
Where we install
The City of St. Louis and the Missouri counties around it — St. Louis County, St. Charles, Jefferson, Franklin, Warren and Lincoln — plus Madison, St. Clair and Monroe counties in Illinois. What changes by area: locations.
