Optional Add-Ons 
  • Rock Solid Assurance Policy, $1,500 – This is an optional, but highly recommended add-on for below ground shelter installs. For a flat rate fee of $1,500.00, NSS will reasonably assume the efforts of removing any and all rock, hard substances or in the worst case…limestone. A concrete slab over 6” inches thick will be considered as rock and subject to additional charge if Rock Solid Assurance is not purchased. This is a non-refundable policy and must be paid at time of execution of a contract with deposit. Below is the cost outline if you do not purchase the Rock Solid Assurance Policy and we hit rock: Day 1 – $1,000, Day 2 – $2,250.00, Day 3 – $2,250.00, Day 4 – $2,250.00, Day 5 – $2,250.00| Max Charge = $10,000.00
  • Debris Haul Off, $575 – This is an optional add-on for below ground shelter installs. NSS will remove all debris from digging and haul it off for you.
  • Georgia Buggy, $450 – This is an optional add-on for below ground shelter installs. The Georgia Buggy should be purchased when it is necessary to keep a concrete truck off of a private driveway.


Project Acceptance
  • I accept and understand the following: my final balance is due upon the unit being set and before concrete is poured, my install location becomes a construction site, the NSS install team will complete a broom sweep cleanup, there might be light residue, dirt, etc. from the install.
