Questions and Answers

Does the standard garage come painted?

Our standard pricing is factory primed and caulked along the vital areas (around the door, vents, eaves, etc.) and is ready to paint. We use DURATEMP© plywood siding that comes pre-primed with exterior latex primer. The manufacturer recommends a quality topcoat of exterior paint be applied. Do not use vinyl acrylic exterior paint.

You can opt for custom painting as an upgrade option on any building. Your garage will be painted with professional paint sprayers and brushes. We can custom match paint to almost everything. Please let us know at the time you place your order for a price quote. Some stock buildings may be painted already.

How tall is the garage?

Measurements listed are taken from the top of the ridge cap of the roof to the bottom of the floor runners sitting on the ground. Your final height depends on the elevation of the blocks used on the runners.

Garage Height:

  • 8′ wide = 9′ 9″ tall
  • 10′ wide = 10′ 10″ tall (11′ 10″ with a 7/12 pitch roof)
  • 12′ wide = 11′ 4″ tall
  • 14′ wide = 11′ 8″ tall

What is the weight of a garage?

This varies by a number of factors. But a few sizes are listed below for a “ball park” reference:

  • 10′×16′ Prefab Garage = 3850 pounds
  • 12′×20′ Prefab Garage = 4420 pounds
