The first step is to research local commercial contractors who have experience working on similar projects. This can be done a few different ways:

Contact local property management groups: These groups typically have a list of recommended commercial contractors that they’ve worked with in the past.
Search online: Many online directories list commercial contractors, such as the Better Business Bureau (BBB) or Angie’s List.
Find similar properties: Try to find similar properties in your area that have been recently renovated. You can then contact the property owners and ask who their commercial contractor was.
Get referrals: Ask family, friends, and business associates if they know of any reputable commercial contractors in the area.

Once you’ve compiled a list of potential contractors, you can start reaching out to them to get more information about their services.

Step 2: Ask for Bids

The next step is to ask each of the commercial contractors you’re considering for a bid. When requesting a bid, be sure to give the contractor all the relevant details about the project, such as the project scope, timeline, budget, and your expectations. This will allow the contractor to provide you with an accurate estimate.

It’s important to note that the lowest bid isn’t always the best option, as it could indicate that the contractor is cutting corners. Instead, you should focus on finding a contractor who provides a fair price for the quality of work they will provide.

Step 3: Review Past Projects

Once you’ve received bids from each of the contractors you’re considering, it’s time to start narrowing down your options. One way to do this is by asking each contractor for a list of past projects they’ve worked on. This will allow you to see the type and size of projects they typically work on and get an idea of their experience level. It’s also a good idea to drive by or visit some of the contractor’s past projects, if possible. This will give you a first-hand look at the quality of their workmanship.

Step 4: Check Their References

Another way to vet commercial contractors is by checking their references. When speaking with a contractor’s references, be sure to ask about the quality of work, if the project was completed on time and within budget, and if any issues arose during the project. It’s also a good idea to check online reviews, as they can provide helpful insights that you may not get from speaking with references.

Step 5: Get Everything in Writing

Once you’ve selected a commercial contractor, it’s important to get everything in writing before work begins. This includes the project scope, timeline, budget, and any other details that have been agreed upon. Having everything in writing will help ensure that both you and the contractor are on the same page and help avoid any misunderstandings down the road.

What are Common Misconceptions About Commercial Contractors?

Many people have a general idea of what a commercial contractor does, but misunderstandings about their role, responsibilities, and expertise are common. These misconceptions can lead to unrealistic expectations, hiring mistakes, or underestimating the complexity of commercial construction. Below are some of the most widespread myths about commercial contractors, along with the facts that clarify them.

Commercial construction requires various permits and adherence to zoning laws, safety codes, and environmental regulations. A contractor who avoids these steps could put your project at risk. Warning signs include contractors suggesting that permits are unnecessary, being unfamiliar with local building codes, or having a history of code violations or legal disputes. Ensure the contractor obtains all necessary permits and follows regulations. Check their history with regulatory agencies for any past violations.

7. High Employee or Subcontractor Turnover

A contractor who frequently changes subcontractors or workers may struggle with management issues, payment problems, or poor working conditions. Signs to look for include frequent replacement of workers in the middle of a project, heavy reliance on temporary labor rather than experienced professionals, and past clients reporting delays due to worker shortages. Ask how long they’ve worked with their current subcontractors and crew. A stable team is usually a sign of a well-managed business.

8. No Written Warranty or Guarantee

A reputable commercial contractor stands by their work and provides a written warranty covering materials and workmanship. Red flags include contractors who refuse to offer any kind of warranty, provide only verbal assurances instead of written terms, or disappear after project completion with no way to contact them. Before work begins, request a written warranty outlining what is covered, the duration of coverage, and how issues will be addressed.

Selecting a commercial contractor is a major investment. Watching for these red flags can help you avoid costly mistakes and ensure a smooth, successful construction project. Take the time to research, verify credentials, and choose a contractor with a proven track record of reliability and quality.
