They did a good job cleaning up along the way and afterwards, we also received a certificate for a cleaning service. Comfenergy kept the job site safe throughout my project. Since we were still living/working in the house during the project, there was constant communication to make sure everyone knew what was going on. We were in constant communication via email, phone and text with the John and all of the workers. I am satisfied with the quality of materials used. All of the materials were of great quality. I am satisfied with the quality of the workmanship. With this large renovation there were very few things that needed attention, and Comfenergy did a great job addressing them to make sure the final product was to our satisfaction and remained professional throughout my project. John and all of the workers were very professional, realistic and organized. Expectations were managed upfront and each part of the project was executed a balanced order. We had several phases to our project to ensure life balance during the construction. Our schedule was flexible and they worked with us every step of the way to get things done safely and correctly. There was a lot of work and scheduling that went in to our project. And so far with some of the hot/humid days that we've had, the house is comfortable and their are no signs of duct sweating in the walls. John went above and beyond for our family to make sure everything was done right so we won't have any future issues. He treated us more like family than customers, and made sure we were happy with everything. Comfenergy came up with a great plan and they were flexible with us when we wanted to add things along the way. We were in constant communication and all of my thoughts, ideas, concerns, questions were received, thoughtfully discussed and executed well.

Q & A

Answers to commonly asked questions from the experts on Thumbtack.

What is a general contractor?

When starting a home remodel or new construction project, you will probably hire a general contractor. A general contractor is a professional who is qualified to take a set of building plans and construct them as outlined. The general contractor may help perform the day-to-day building, or they may just hire workers and oversee all the work activities. In either case, the job of the general contractor is to see that your project gets built.

When you have a building project, ask for bids from various contractors. The bids tell you how much each will charge and what their scope of work will be. Once you have selected a bid, you sign a contract with that general contractor outlining the specifics of the project and the milestones during the project when they will receive payment installments. Once the contract is official, the general contractor will bring in their crew to begin construction. The contractor will manage the workers and subcontractors (anyone who doesn’t work directly for their company but that they need to outsource, like a marble installation pro), order all the materials, obtain work permits, and confirm that all the workers and subcontractors are completing their projects as planned. They typically handle all the payments to the workers and subcontractors, and send you invoice. For all these reasons, it’s also especially important to follow a few smart hiring practices when it comes to finding a general contractor.  If you are organized and competent to oversee construction projects, and are able to make sure everything is being built properly and meeting code, it’s possible you can be your own general contractor.  

How do you choose a commercial general contractor?

A commercial contractor provides similar services as a residential general contractor but specializes in working with large-scale projects for businesses, schools, nonprofits, governments and development firms. When researching commercial general contractors, review their portfolio of work and confirm they have ample experience working in the area you need. For example, if you are building a small strip mall, ask if the contractors have experience successfully incorporating all the needed elements such as a parking lot, meeting ADA requirements, accessing the proper permits, and completing work on time.

Once you’ve identified several qualified candidates, request bids for your project and then compare the scope of work with your needs and budget. Your commercial general contractor should oversee design, permitting, construction, materials purchase, and adherence to building code and zoning regulations, as well as sticking to an agreed-upon budget and schedule. It’s important to establish clear communication with your future commercial general contractor, as this will mean a smoother process for everyone. For all these reasons, it’s also especially important to follow a few smart hiring practices when it comes to finding a general contractor.

What do general contractors charge?

If you’re doing a home remodel, building a new home or embarking on a commercial building project, you’ll hire a general contractor. A general contractor is a professional who is qualified to oversee and execute construction projects. Each construction project is unique; even two duplicate homes built on lots next door to each other could have different construction costs due to factors like different excavation costs when building the foundation. Since each project is unique, many general contractors make bids on potential construction projects. These bids can then break down to a per square foot cost that encompasses the labor of all the workers needed for the job, materials, the scope of work, and any equipment needed. Materials and finishes make a major difference in your cost per square foot. For example, choosing standard kitchen tiles at $3 per square foot will result in a lower total project cost than imported marble tiles that cost $63 per square foot. Where you live will also affect how much general contractors charge, as labor and the cost to do business can cost less in many regions than in high-cost areas like New York or San Francisco. Here are some examples of average costs general contractors typically charge in various regions:

  • Home addition in San Francisco: $250-$270 per square foot.
  • New home construction in Knoxville, Tennessee: $100-$200 per square foot.
  • Kitchen remodel in Tennessee: $40-$80 per square foot, depending on finishes.
  • Bathroom remodel in Vancouver, Washington: $110-$170 per square foot.
