"It's hard to over exaggerate how pleasant it was to deal with Matt. He was professional, straight forward and reliable. Hard to find in the construction business. His work is of superior quality and he was competitively priced. I had found Matt completely by chance on Angie's list while desperately cold calling woodworkers to fabricate and install a curved ledge tread on a landing. Who knew that curved ledges are astronomical to fabricate. I didn't trust my contractor to put the expensive piece in - he had already stuffed up my hardwood floor. I found Matt very easy to talk to, he came by to take a template of the ledge before I agreed to hire him, he came when he said he would and the work was done well and on time. I have a ceiling that I would like some wood paneling on, and have hired him to do that as well."

Generally, general contractors charge between $50 and $150 hourly, though not every contractor charges by the hour. If charging based on the project, you can expect a markup of 10% to 20% of the construction cost. You can expect to pay between $300 and $500 daily if charged by the day.

General contractors are the ones that coordinate home construction projects. They are in charge of the day-to-day oversight of the subcontractors to ensure that the project is completed on time and to resolve problems as they arise. General contractors:

Complete pre-construction planning, both with the customer and crew
Provide realistic cost estimates
Develop construction timelines
Ensure deadlines are met
Acquire permits as needed
Purchase supplies and materials

Before hiring a general contractor for your home project, it’s a great idea to write down a list of questions to discuss with each prospect. Some example questions to get you started include:

Which types of insurance do you carry?
Can you provide a list of references?
What is the expected timeline for this project?
How will my project be supervised?
Will you hire subcontractors for the job?
What is the best way to communicate changes?
Will you obtain all of the required building permits?

While city and state laws vary on general contractor licensing requirements, hiring an unlicensed general contractor could lead to poor quality work, costly future expenses, and potential code violations.

As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include:

The owner, principal, or relevant manager passed a criminal background check
Required to have applicable state and local licenses

Yes, most general contractors require a down payment for project completion.
