Quick Answer:
Below-ground storm shelters in Oklahoma provide excellent tornado protection with straightforward installation and ownership. Expect a 3-4 hour installation process, possible water entry during heavy rains since doors aren’t airtight, and simple maintenance like greasing hinges every 6 months. Sprague’s Backhoe installs precast shelters that meet FEMA guidelines throughout Oklahoma’s 30-mile service radius.
If you’re thinking about getting a below-ground storm shelter here in Oklahoma, you probably have questions about what it’s really like. After installing hundreds of these precast shelters across central Oklahoma since 2013, we know what families actually experience.
Let me walk you through what to expect with a below-ground storm shelter, from installation day to living with one through Oklahoma’s storm seasons.
Installation Day: Faster Than You’d Think
When we arrive to install your shelter, the whole process takes about 3-4 hours from start to finish. We bring our backhoe, dig the appropriately sized hole for your precast shelter, the manufacturer sets it in place with the crane truck, and then we backfill around it.
It’s pretty straightforward work. You’ll see some equipment on your property for a few hours on installation day, but by afternoon or evening you’ll have a fully installed storm shelter ready for Oklahoma’s next severe weather event.
After installation, you’ll have a small access area in your yard with the door. Many families work this into their landscaping, and it becomes a natural part of the property.
Water Reality During Oklahoma Storms
Here’s something important to understand: the doors aren’t airtight, which means they’re not watertight either. During heavy rains, especially when Oklahoma’s storms bring driving rain, some water can come in around the door.
This is normal for storm shelters. The doors need to open easily during emergencies, so perfect sealing isn’t practical. Most families just accept that severe storms sometimes mean a little water to deal with afterward.
In most shelters we’ve installed, water accumulation has been minimal and dries quickly. However, in areas with poor drainage, homeowners may experience more significant water intrusion requiring added mitigation. If water does accumulate, most people can dry it out by opening the door on the next dry, sunny day to let the shelter breathe and air out naturally.
Size Options for Oklahoma Families
We install three below-ground sizes, and your choice depends on your family’s needs:
6×8 Standard Shelter comfortably holds 10-12 people. This works well for most families, with room for neighbors who might need shelter during warnings.
6×8 Easy Access accommodates 8-10 people but features easier entry with more gradual stairs. If you have family members with mobility concerns, this design provides better accessibility. Learn more about our Easy Access Storm Shelter option.
7×10 Large Shelter fits 14-16 people. Families choose this when they regularly host extended family or want extra space for emergency supplies.
Simple Maintenance You Can Handle
These precast shelters are built to last with minimal upkeep. Your main maintenance task is greasing the door hinges every 6 months using the grease zerks – the manufacturer includes this in their recommendations, and it keeps the door operating smoothly.
Beyond that, keep the drain area clear of debris and do an annual check of your emergency supplies before storm season starts.
Your shelter comes with a manufacturer’s 10-year limited warranty, so you’re covered for any structural issues during that period.
Seasonal Life in Oklahoma
Spring through early summer is when you’ll use your shelter most. During tornado season (April through June), many families do practice runs so everyone knows the routine.
The shelter generally maintains a stable underground temperature. Many report temperatures around 60–65°F, though this can vary depending on soil, shelter depth, and ventilation.
Some families install a small padlock or combination lock on the outside door (there’s a spot designed for this). Just remember to keep the key or combination easily accessible for quick entry during warnings.
Permits and Paperwork
You’ll be responsible for obtaining any storm shelter permit your city requires. We’ll provide all the documentation you need for the permit application and handle any contractor licensing requirements on our end.
Permit requirements vary by location, so check with your local building department about what’s needed in your area.
