10 Most Common Questions


  • Q: How long will it take to get my building delivered after I place an order?
  • A: Usually 2-4 weeks from the date that you are ready to have your building installed. If your order is received and you are not ready, the 2-4 week window begins when you are ready to take delivery of your building. Do keep in mind that during the summer and early fall, delivery windows may increase based on customer demand. (Remote areas make take longer).


  • Q: What are the dimensions of the building, outside to outside?
  • A: Our building measurements are Width x Length x Height.
    • For Example: An 18’ x 21’ x 6’ building’s base frame size is 18’ x 20’ x 6’. The roof metal overhangs 6” on each end so the bottom base rail frame dimension is one foot shorter than the roof. The width is measured from the outside of the baserail to the other outside of the baserail. Visit our Carport and Garage Installation Guide for more details.


  • Q: What size do I need to pour my cement slab?
  • A: You should pour your cement exact to width and 1’ shorter than the roof. In Florida, the cement should be ¾” wider than the width and 1’ shorter than the roof. For Example: In all states except Florida, the slab for a 18’ x 21’ x 6’ unit needs to be 18’ x 20’. In Florida, the slab for the same unit needs to be 18’ ¾” x 20’.


  • Q: What is the highest side height that I can get?
  • A: 14’ is the highest side height that is is offered.



  • Q: When are the extra 4’ braces required?
  • A: 4’ braces are required when the side height is 8’ or taller on all sizes of open carports. They are not required on enclosed buildings but we always recommend them. On certified open carports in all states except Florida, they are included in the price.


  • Q: Could you make additions to the building after it’s already installed?
  • A: In most cases, yes. There will be a minimum service charge of $50 or more on all return trips. Be advised that:
      • We will only add to buildings that we have sold.
      • Adding gable ends and walk-in doors on the side wall requires that the unit be at least 7' tall. To   add garage doors will require that the unit be at least 1’ taller than the garage door height..


  • Q: What types of anchors do you use?
  • A: We have four different types of anchors. They are:
      • For non-certified ground/asphalt installations, 32” rebar anchors. This is our standard ground anchor for all non-certified units.
      • For ground/asphalt installations that are certified, double helix mobile home anchors are used. Those anchors can be used on non-certified ground installations at an additional charge and they are recommended.
      • Lag bolts for wood installations. Be advised wood installations cannot be certified.


  • Q: What is the widest building that I can get?
  • A: We manufacture clear span buildings from 12’ to 40’ wide and other custom buildings up to 68’ wide.

  • Q. What roof styles do you offer and what are the features of each style?
  • A. We offer three roof styles. They are:
      • Regular style units have rounded corners and are considered the “basic” of carport designs. Acting as a founding product for all other designs, the regular style unit is typically the most economical and affordable product
      • Boxed Eave units are designed with an “A” frame roof truss and horizontal roof panels. This modern design has made this style unit one of the most popular available. An upgrade to Boxed Eave style is both stylish and affordable.
      • Vertical Roof units are designed with an “A” frame roof truss and vertical roof panels. Hat channel runs the length of the unit to cross brace the roof and provide a mounting point for the roof panels. This design helps to prevent weathering elements such as rain and snow from “standing” on your building. Vertical Roof units come standard with ridge cap and specially designed wider trim that give the product a modern, finished appearance. for more information about our roof styles visit our roofing systems page.

Mobile home anchors are an optional upgrade for non-certified ground installations and they are always recommended.
