Q & A

Answers to commonly asked questions from the experts on Thumbtack.

What do construction project managers do?

Construction project managers help in all stages of your construction project, starting from the very first step. Typically paid a percentage of a total project cost, they are part of the design and planning process and help ensure seamless communication between the design parties and the construction team. According to the U.S. Department of Labor, their scope of work includes preparing cost estimates, budgets and work timetables; interpreting and explaining contracts and technical information to other professionals; reporting work progress and budget to clients; collaborating with architects, engineers and other construction pros; selecting subcontractors and scheduling and coordinating their tasks; responding to work delays, emergencies and other problems; and ensuring compliance with legal requirements, building and safety codes, and other regulations.

The work of construction project managers may seem very similar to that of general contractors, but there are some critical differences. One difference is that, unlike most general contractors, project managers are not engaged in the actual construction — they are onsite overseeing the work of subcontractors. Another key difference is that project managers are hired during the design phase, while general contractors are hired after plans have been made. The project manager is generally paid a percentage of the total project cost, while the general contractor is more typically paid according to the bid they gave to build your project.  

Why should you hire a contractor?

Hiring a general contractor is a good idea for many remodeling projects. Home renovation contractors have a broad range of skills to manage, coordinate and complete a project. They should help make sure your project comes in on time and within your budget as they hire and supervise all the necessary subcontractors, including electricians and plumbers. They also handle procuring all the materials required for your job. Some homeowners look to save money by acting as their own contractor, but an experienced home renovation contractor is worth the cost. They should know local building codes, be able to pull all necessary permits, and work with inspectors to make sure the construction meets local codes. Also, because they get professional discounts, they can typically buy materials at a better price than you can; better prices on materials and labor save you money, and make up for at least a percentage of the cost of the contractor.

What is a contractor license number?

A contractor license number is proof that your contractor is operating their business legally, that they have the proper documentation required by your state or region, and that they are competent in their area of work (electrical, plumbing, construction, etc.). Licensed contractors should freely advertise their contractor license number. If not, you can request it before considering them for hire. You can also research your contractor using their license number. The database for your state will indicate the field they are licensed to work in; whether they are up to date on insurance, workers’ compensation and bonds; and whether they have any consumer complaints issued against them. If the licensed contractor you are hiring does not have employees, they are not required to carry workers’ compensation. Each state or region will have their own database for licenses, such as the State of Oregon Construction Contractors Board. For more, check out our tips for smart hiring on Thumbtack.  

How do I find out if a contractor is licensed?

It’s important to know if your project requires work by a licensed professional, as licensing laws can vary by state, locality, and job details. You can find general licensing information online at the government websites that handle occupational licensing for a given profession in your state or location. Some states designate a project cost over which you have to hire a licensed contractor. To find qualified licensed contractors, search your state’s licensing board. For example, in California, the Department of Consumer Affairs operates a searchable database through the Contractors State License Board. In some states, contracting licenses are provided at a regional level. You can find links to specific databases on BRB Publications’ Occupational Licensing page. Red flags that a contractor may not be licensed or may be providing an expired or false license number are unreasonably low bids or a request for complete payment upfront.

When should you hire a contractor?

A few home remodeling projects can be done by an ambitious DIY-minded homeowner or local handyman, but many are best completed by a professional home renovation contractor. You should hire a contractor when you’re planning a large project that takes time, machinery or large tools, and several workers; a kitchen remodel, new bathroom or home addition will be most successful with a licensed, expert contractor at the helm. It’s particularly important to have a professional contractor on board for construction, electrical, plumbing and HVAC projects that require inspections to meet local building codes. Of course, you can hire a contractor for smaller projects, too, if you prefer to let an expert handle things like addition or removal of a wall, small framing projects, or anything that requires a permit.  

You should hire a contractor when you’re ready to start a remodeling project and you have plans, a budget and a timeline for the work in hand, but before any remodeling work begins.
