Cumberland Buildings - Gateway Realty

Why Choose Cumberland?

Unlike some companies, we fabricate portable storage buildings with top-notch materials for lasting durability and great value. Here is a list of features you will appreciate having in your new building:

  • Exposed nails are ring shank and galvanized for maximum strength and no rust spots or stains.

  • The 2×4” reinforced doors are designed to seal out rain and include key locks for added security.

  • Air vents are positioned to create optimal circulation and temperature control to protect your belongings.

  • Floors are built with 5/8” pressure-treated decking to prevent rotting.

  • Floor joists are created with pressure-treated boards and positioned 16” on center for 10’ wide and larger buildings and set into notched 4” x 6” pressure-treated skids for maximum strength and durability, especially under heavy snow loads.

  • Garage floor joists are positioned 12” on center to carry the extra weight of ATVs, large mowers, cars, etc.

  • Painted buildings are built with LP® SmartSide® panels.

  • Metal roofs and wood shingles are provided at the same price.

  • If stain or painted siding is chosen, the cost is included in the quoted price.

  • Wood buildings are water sealed at no extra charge.
