Unless you're in the business, managing a major home remodeling job may be too much for the typical homeowner to handle. Each pro you add to year team adds costs but putting the right team together may be the key to getting your project done on time and on budget. Here are the home remodeling experts you may need and some you can probably skip.

Architect

What they do: Listen to your ideas, help you think through the design, and translate all of it into drawings for the general contractor to follow.

When you need one: You’re knocking down walls or chang­ing your home’s structural or mechanical systems.

What they charge: 10 to 20 percent of overall project cost.

General Contractor

What they do: These MVPs take charge of the project from start to finish, managing the schedule and hiring plumbers, electricians, and all other subcontractors. General contractors also secure all necessary permits.

Interior or Kitchen/Bath Designer

What they do: Help with design choices, such as selecting a kitchen countertop or the tile and tub for the bathroom.

When you need one: Trying to decide between granite, quartz, and laminate countertops is driving you insane.

What they charge: 4 to 7 percent.

Renovation Consultant

What they do: Help you plan, determine your budget—they’ll even be the liaison between you and the general contractor during the entire renovation.

What they charge: Up to 5 percent.
