What to Expect During Above Ground Storm Shelter Installation in Duncan
Every above-ground storm shelter installation in Duncan, Oklahoma and throughout Stephens County is site-specific. Yard layout, surface grade, soil conditions, and access all affect where an above-ground shelter can be safely installed.
Placement is discussed on-site with the homeowner. We install the shelter in the chosen location as long as it allows for proper truck and equipment access, drainage considerations, and long-term stability.
Placement & Leveling
Above-ground storm shelters are installed directly on native ground, as required by the engineered design.
If needed, we scrape and level the installation area at no additional charge.
Each shelter includes a 5-inch poured concrete floor as part of the unit itself. The shelter is designed to be anchored into native soil, rather than bolted to a surface-mounted concrete pad.
Installation & Pricing
Professional installation by Sprague’s Backhoe is included with every above-ground storm shelter. We do not offer wholesale pricing or customer-installed options.
Pricing reflects a complete installation, from delivery and site preparation through final placement and anchoring.
Anchoring & Soil Conditions
Our shelters are designed to be anchored in all Oklahoma soil types without requiring special site preparation.
Payment & Deposit Information
We accept cash, check, and card payments. A 4% convenience fee applies to all credit and debit card payments.
If you have questions about payment timing or accepted methods, we’re happy to go over details before installation.
If you’re still deciding which size or layout works best, our above-ground storm shelter page explains the differences in more detail.
