Q: Do your prices include delivery and installation?

A: Our prices do not include delivery or installation. Every location is different and prices vary from location to location. We will work directly with you to provide up-front pricing and competitive options.

Q: Do you install in my area?

A: DEFCON Underground delivers and installs underground bunkers in the entire United States, including Alaska and Hawaii. Delivery charged and installation fees will be impacted in areas unreachable by ground shipping.

Q: Can i install my own bunker?                                                                                                                                                                   

A: Yes you can, however if you do not have a good grasp on construction, welding, or excavation we do not suggest it. 

Q: Can you attach to my existing basement?

A: Yes, we can hook up directly to your existing foundation wall. It is our goal to provide easy access to your bunker in case of an emergency situation. However, if the owner chooses, we also offer off-site entrances for privacy purposes.

Q: Do you use any outside contractors?

A: No, we build, deliver, and install your underground bunker to reduce the number of people who know about your new bunker’s location. In the event that we need to use an outside agency, your privacy will be our highest priority. We will sub-contract all vendors in your area under a different company name. This name is not associated with any bunker or survival company. 

Q: Will we have to get a permit from the city?

A: Every city is different, so each home owner will bear the responsibility of contacting his or her local city officials. In most situations, a permit will not be required. In the event that a permit is required, we will help you through the process. We are familiar in dealing with city development officials and the codes associated with these projects.

Q: Is there a paper trail associated with my Underground Bunker?

A: No. Shortly after your unit is installed, we will destroy all records associated with the location of the build. The only records we will retain will be for accounting purposes. Should you choose, you may use a P.O. Box for correspondences.

Q: Will my bunker be ready to live in after the installation?

A: After installation of your bunker, you will be ready to take your survival preparations and loved ones inside and begin your life underground.

Q: Can I put a generator inside the bunker?

A: Yes, you can. All of our bunkers are designed with a sealed and ventilated room specifically for this purpose. 

Q: Are bunkers dark inside them?

A:  No, in fact they are very bright inside. We utilize the latest technology in energy efficient LED lighting.

Q: How long does it take to install my new Underground Shelter?

A: Most units can be installed in 2-5 days from delivery to completion. Once you are finished selecting your unit and optional upgrades, we will let you know the time-frame for your installation.

A: Once an order has been placed and material is ordered your deposit is non-refundable.

Q: How deep can your units be buried?

A: Our bunkers are buried anywhere from 36”-72” deep. During our on-site visit, we will be able to locate the ideal depth for your bunker.

Q: Where will my bunker ship from?

A: Freight depends on the model you choose. Each flatbed truck runs around $4-$6 a mile depending on fuel prices at the time of transportation. 

Q: Do your units come with air filtration?

Q: When looking at companies to buy a shelter from what should i look for?                                                                                       

A: Do they have a professional engineered stamped drawing.  

Q: What is the difference between a survival shelter and a bomb shelter?                                                                                            

A: A survival shelter is a shelter that is designed to be burred underground and is engineered for a live load and a dead load. Bomb shelters are burred underground to a certain depth that is figured by the size of the bomb and distance from detonation of the anticipated blast. Almost all bomb shelters will be encased in reinforced concrete. These shelters will be engineered for live load, dead load and a blast load. Bomb shelters are normally given a survivable PSI rating. A shelter that is just burred underground does NOT make it a bomb shelter. 

Q: How long will i need to stay in my shelter after a nuclear blast?                                                                                                        

A: In most cases you will be able to exit you shelter in 30 days. Typically after 28 days, 99% of the radiation emitted by the fallout will have decayed.

Q: What types of power are available for my shelter?                                                                                                                                

A: We always suggest multiple types of power sources. We also suggest having redundant systems in place. Common types of shelter power are Solar power with battery battery back up, Diesel generators and Shore/Grid power. We can configure you power system to run on multiple power sources and switch between them automatically as needed.

Q: Who long can i stay in my shelter?                                                                                                                                                          

A: You can stay in your shelter as long as you have food water and other supplies. We suggest to have at least 30 days of needed supplies at all times. 

Q: Can my Bomb Shelter survive a direct hit from a nuclear blast?                                                                                                          

A: NO, almost no Bomb Shelter can survive a direct hit. Not even most military Bomb Shelters can survive a direct it. A mile out or sometimes even less can be survivable though.

Q: Do you finance?

A: YES we do. Financing a bunker is a very hard procedure and most banks will not lend. However, we have obtained a few lenders who are willing to work with you dependent on your credit score and your bunker’s type and location.
