Subcontractors questions, answered by experts

There are several different steps in the pole barn building process. First, you’ll need construction plans, which you’ll use to obtain permits. Then, you can clear the land so it’s suitable for building and installing the foundation. Your contractor will frame the barn using large poles, then rough in the plumbing and electricity (if your barn has those elements) before finishing the interior, adding siding, and installing the roof. 

After that, they’ll finish up the electrical work and plumbing and add your windows and doors. You may have a few other finishing jobs to do like painting or waterproofing.

Most commercial projects take 3-7 days, including curing time, depending on size and weather conditions.

On average, the cost to transform your garage into a workshop is about $2,000. The overall project cost depends on the type of workshop you want to build and its size. Regardless of the type of workshop, you’ll still need basic workshop spaces and equipment such as a workbench, cabinets, and space for storage and for working.

While it can be easy to reupholster small items like outdoor cushions or pillows yourself, bigger projects are better left to the professionals. Hiring a professional reupholstery service is the best way to ensure your furniture is properly fixed, especially if you’re working with larger pieces, like couches, or high-end materials, like leather, where mistakes can be costly.

Structural engineers are necessary for projects involving alterations to load-bearing structures, foundation work, and compliance with safety standards. This includes home expansions, retaining walls, and significant repairs that impact a property's integrity.
