I asked Sam to help in building a lego/crafting desk in the basement for our family. He happily took on the project and did an outstanding job in not only building the desk but providing great feedback and changes to the design that helped create the beautiful and stable desk we have now. He also installed a new drop light and electrical outlet in the same room for us that came out great. I would highly recommend him for any project. He is honest and very trustworthy with his work and a great communicator.

This is my first time using Thumbtack. Mike at S.H.N LLC Designs did a great job. I needed drywall repaired on a couple of walls. He responded within minutes and came out the same day to give me a quote. I would hire Mike again, we already discussed a future basement project and I would recommend him to friends.

We just completed a full basement (from the studs) renovation with Eduardo and we couldn't be more impressed with the BBC team. The quality of work for the price can't be beaten and Eduardo and his subs worked hard to meet our tight deadline without compromising quality. Eduardo is knowledgable and trustworthy and professional while he and his team are very considerate and thoughtful. We would highly recommend Boston Best Construction and have our next renovation project lined up with them already!

Stan came and fixed a rotted basement sill and cracked floor joist. He went out of his way to readjust his schedule because we were on a time crunch to get some work done prior to a home inspection. The work was completed in a timely manner and the cost was more than fair. I would recommend him to family and call him in the future for any other work that we might need done.

Richard helped me disconnect old washer/dryer and install new ones. He even hauled away old ones without extra charge. Since my washer is in a small bathroom in basement, it took him longer time to remove old appliances. But he kept the original quote. I would recommend Richard to others who need to install new washer/dryer.

We hired Adam to put a floor in our condo which required a ceiling as well since the condo had a sunk in living room. This made a new room and created a finished basement for us. We also had him put up a new wall to create a third bedroom. His estimate was very reasonable and the final cost matched his estimate to the penny. He was very professional and turned the job around in less then two full weeks. I would definitely recommend him and will hire him in the future if the need arises.

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.
