Allen Construction has been constructing light commercial and residential buildings for 35 years. During that time we have built tornado shelters and safe rooms in new homes, but the time and cost discouraged most homeowners from making the decision to add a storm room. In searching for an answer for a solution to my own needs, I found what I believe is the best and most economical answer to providing protection from tornados and severe storms.
We offer many styles of tornado shelters, but I felt the best one for my needs, and the needs of many others, is a steel unit that can be placed in the garage, or if a home is on a concrete slab, anywhere in the house. The advantages are accessibility, and not having to go out in severe weather to get in a tornado shelter.
We offer only certified tornado shelters and we are an installer member of the NSSA (National Storm Shelter Association. In doing my research, I felt that only certified shelters should be installed.
Recognized certification means a storm shelter has been successfully tested at the Debris Impact Test Center at Texas Tech University in Lubbock Tx. Then wind engineers evaluate and analyze the storm shelter for structural strength and safety and that the storm shelter meets all ICC codes, etc. A seal is provided by the National Storm Shelter Association to us and we affix the seal with a serial # to the storm shelter and the customer receives a certificate registering the certified storm shelter with the NSSA.
