Top 10 Questions

  • How long will it take to get my building delivered after I place an order?
    Delivery times vary depending on your area although it is generally 2-8 weeks from the time your order is received. Call our office at 855-711-5347 (toll free) to speak with our knowledgable staff.
  • What are the dimensions of the building, outside to outside?
    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’. Note that the measurements stated are the dimensions of the roof metal. It has a 6” overhang on each end so the bottom base rail frame is one foot shorter than the roof. The width is measured from the outside of the baserail to the other outside of the baserail.
  • What size do I need to pour my cement slab?
    You should pour your cement exact to width and 1’ shorter in length. For Example: The slab for a 18’ x 21’ x 6’ unit needs to be 18’ x 20’.
  • What is the highest leg height available?
    12’ is the highest that is listed on our 12’ – 24’ wide brochure. Leg height over 12’ requires approval by CCI management. 14’ is the highest that is listed on our 26’ – 40’ wide brochures. Customer must provide a lift during installation on buildings wider than 30’ that are more than 12’ tall.
  • Does my installation site need to be level?

    In most cases, yes. There will be a service charge of $50 or more on all return trips. We will add to CCI buildings only.
  • What types of anchors do you use?
    We have three different types of anchors. They are:
    • For ground/asphalt installation, 32” rebar anchors.
    • 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.
    • Wedge anchors for concrete installations.
  • What is the widest building available?
    Clear span buildings from 12’ to 40’ wide and other custom buildings up to 68’ wide (barn style buildings) are available.

Anchoring Questions

  • How is my carport anchored to the ground or dirt?
    On non-certified units, 32" long rebar anchors are inserted through pre-drilled holes in the base rail. The anchors are driven into the ground with a sledgehammer for a secure hold. On certified units, double helix mobile home anchors are augured into ground and a bolt is inserted through pre-drilled holes in the side of the base-rail. The bolt is secured with a nut. Mobile home anchors are an optional upgrade for non-certified ground installations.
  • How is my carport anchored to my concrete slab?
    Holes are drilled into your concrete slab. Wedge anchors are inserted through pre-drilled holes in the base rail of your unit into the holes in the concrete and fastened for a secure hold.
  • How is my unit anchored to ashpalt?
    On non-certified units, 32" long rebar anchors are inserted through pre-drilled holes in the base rail. A small hole is made in your asphalt and the anchor is driven into the ground with a sledgehammer into the asphalt. For certified units, mobile home anchors must be used.
  • How is my carport anchored to a wood surface?
    Lag bolts are inserted through pre-drilled holes in the carport base rails and screwed down into the wood surface for a secure hold.

Construction Questions

  • What roof styles do you offer and what are the features of each style?
    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.
  • Can I order a custom sized unit?
    Yes. For example you may need a unit that is 23' wide x 24' long. We will make it that size. Please call us at 855-711-5347 (toll free) for additional information.
  • Do color choices add to the cost of my unit?
    No, you may choose any of our 13 colors. You may choose one color for the roof, a different color for the trim, a different color for the sides and if a gable end is desired a different color for it at no additional charge. You may also choose to make all of the colors the same on your unit.
  • Can I buy a carport or garage in a kit and assemble it myself?
    Yes, units are available for drop-off only. All materials will be delivered to your location. No assembly instructions are provided. We highly recommend that you have your unit installed by a professional contactor.
  • What are certified buildings and why should I purchase one?

Many areas, particularly in the northeast and along the coastal regions, require that the buildings meet a specific wind or snow load. You should be aware of your area's requirements and purchase a structure that meets the wind and/or snow load requirements for your area. We service a wide territory and since requirements can change from city to county, it is your responsibility to know the requirements and to purchase a structure accordingly!
