Why Should I Hire a General Contractor for a Room Addition?

Many home improvement projects are probably within your ability level, enabling you to work on your house to increase its value and your personal enjoyment. A project like a room addition, however, requires the services of an expert to ensure that you have positive and high-quality results.


A general contractor has the expertise and skills necessary to manage and oversee an entire project from start to finish. The work required to oversee each detail can be extensive and challenging when adding a room to your home – probably more than you have the time or the inclination to handle.

  1. 1.Design & Planning

    Many general contractors offer design and planning services to provide clients with expert concept ideas. You may have thoughts about features you want or a style you envision in the finished result of your project. After communicating these desires to a general contractor, you’ll receive a comprehensive plan and design that incorporates your ideas and desires.


    With a general contractor heading up your project, you have the assurance of knowing that you’ve hired an expert with the skills necessary to plan and design your project. Projects that involve adding a room onto your home must adhere to local building codes to meet health and safety standards. A general contractor will understand these regulations and ensure that your project meets the codes.

  2. 2.Preparing the Site

    Once you’ve planned and designed the project, a general contractor will prepare the work site for the job to begin. The preparation of the work site is an integral step for the entire project. If a crew member doesn’t proceed correctly with site preparation work, it can negatively affect the entire process. Excavation might be necessary for a ground level room addition. To add additional stories to a structure, stabilizing work must occur first. A general contractor possesses the expertise necessary to complete site preparation correctly, without causing damage to your home.

  3. 3.Selecting Materials

    A general contractor brings knowledge and skills to a project that enables efficient selection and purchase of materials. With a general contractor working on your project, this professional will help you choose building materials and fixtures and will then order them and arrange for the delivery to the work site. A general contractor often has connections for building materials that may facilitate better prices or a wider selection, making them the perfect resource to utilize.


    Explore the option of purchasing your own materials, if you prefer. By purchasing your own materials, you can have more control over the selection process and you might save money in some situations. Not all general contractors will allow you to purchase your own materials, however.

  4. 4.Managing the Project

    A quality general contractor will oversee the entire work project, including designing, scheduling, material procurement, project budgeting and hiring subcontractors. Expect to sign a contract with the general contractor to cover the services performed. The contract should include starting and ending dates of the project, payment schedule and a statement regarding lien wavers for all contractors involved as well as materials. Once the project begins, the general contractor will have the responsibility for overseeing and managing all aspects of the project to ensure that it proceeds on schedule and according to the design plan you created.

  5. 5.Problems That May Arise During the Job

    Even with an iron-clad design plan, it’s possible that problems will arise during the construction process. Unexpected issues could occur in connection with a remodeling job involving preexisting conditions in a home. After demolition or tear-down of existing structures begins, underlying problems such as mold or structural problems might appear. When this happens, the general contractor will need to reassess the project so it includes remedial work to resolve the issues before the contracted work can continue.

  6. 6.Benefits of a Room Addition

    If you’re outgrowing your current home, a room addition can resolve your space issues without necessitating an expensive and inconvenient move. Creating more space for living or storage can increase the value of your home and make it more attractive for prospective buyers if you do decide to sell later.

  7. 7.Price Vs. Quality

    As with almost anything, you can prioritize price or quality as you hire a general contractor. By choosing a contractor with lower fees, you might sacrifice quality and even the quantity of services you receive. Some contractors might have lower prices and less experience and skills, while other contractors offer solid experience that will bring dependable skills and expertise to your project, at a higher price. The average price for a room addition to a home is $4,791, with a range from $838 to $27,404 being possible when you hire a room addition contractor to oversee this renovation project.
