Subcontractors questions, answered by experts

General contractors typically manage home renovation or build projects that last more than a week and involve various skilled tradespeople. Some examples include building a new home or barn, adding an extension or garage, or carrying out major room remodels involving extensive plumbing, electrical, and structural changes.

Yes, most general contractors require a down payment for project completion. A reasonable down payment for a contractor is 10% to 25% of the total project cost, though that will vary based on project size and location. The down payment helps cover the upfront costs of materials and permits and helps ensure payment for the project at hand. 

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.

A construction lien results from unpaid services. For instance, if a homeowner hires a contractor to do a large renovation on their home and then fails to pay for the services and materials, the contractor can take out a lien on the property. This lien is a legal claim against the property for the amount of money owed. If the homeowner does not pay their debt, the lien may stay on the title until the homeowner tries to sell and cannot do so until the title is cleared.

In most cases, a contractor will ask you for a deposit that is a percentage of the total cost of your job, but you should never pay in full before work has begun. The up-front cost could be as much as 50%, or you might give a contractor as little as 10% up front. Discuss payment terms with your contractor before they begin the job to avoid surprises.
