    "Jacob and Cody have been amazing to work with. We originally hired them to repair our stairs and have since contracted with them to install our kitchen tile floor, install electric in our kitchen island and to repair some of our drywall. Their team is very professional, their estimates are accurate and they do quality work. We plan to hire them again when we remodel our bathrooms."

    "Overall good experience. Worked directly with the General Contractor, he was able to work around my schedule and ensure that all subs completed their work to our standard the first time! Upfront pricing, honest and provided flexibility in price. For example, I wanted to have my own painter. Additionally I purchased my own vanity and shower. He provided just a labor quote. Iâ ve already recommended to two friends!"

    "I am a business owner who was searching for a reputable construction company that could build out a kitchen and bathroom along with cutting-in and installing two new, exterior windows to our office space. This project had a fair amount of urgency to it and the difficult part is we weren't going to stop meeting with our clients during the renovation so we were going to need to work around noise levels, etc. Thankfully HomeAdvisor connected me with Pernikoff Construction Company as I can't say enough good things about them! They were professional, timely, organized and incredibly pleasant to work with. They kept the lines of communication open at all times and every single person they sent out to work on our job were gracious and knowledgeable professionals. They each had their little specialities they were there to work on and every single one of them worked with us to keep the noise to a minimum when we had in-house client meetings. All-in-all, I am so happy and relieved that HomeAdvisor was able to connect me to Pernikoff as I really could not have asked for a better construction company to complete my office renovation. I would highly recommend them for any project that you will want completed in a timely and professional manner!"

Frequently asked questions

  • It’s important that you verify their license is still in good standing. Also keep in mind that certain states or provinces don’t require licensing if the job is under a certain dollar amount.
  • You can find a list of your state’s licensing requirements on the HomeAdvisor website. Before you get to work with the pro, make sure their qualifications are current and acceptable to you.
  • It is always a good idea to get a copy of the pro’s insurance certificate for future records, and in case anything happens. This is a good way to feel more secure in your home project, and to weed out potential scammers.

HomeAdvisor makes it easy to connect with pros near you. You can read reviews, get quotes and book appointments all in one place.

Depending on the type of project, you may find subtle differences in the hiring process. Here’s a look at task-specific advice.

You can use HomeAdvisor to help evaluate a contractor’s qualifications. We put pros through a screening process, and award badges to high-performing contractors. You can find these badges on a pro’s HomeAdvisor profile, and sometimes, his or her website. 

Your research doesn’t stop here. Once you’ve found a few prospective companies, make an call to ask a few questions about work history, licensure and more:

  • Have you completed a job like this before?
  • Do you have a list of references I can contact?
  • When are you able to start the job?

In most cases, the responses you get to these three questions will give you a very good idea of the right pro for your project. If you have more than one front-runner, these additional questions can help you narrow it down. 

  • How many years of experience do you have?
  • What’s your permanent business address?
  • Are you licensed to work in my area?
  • When did you earn your business license?
  • How do you handle warranty service complaints?
  • Do you have worker’s compensation, property damage and personal liability insurance?

Any good contractor will answer these questions, and most will appreciate dealing with a client that takes such an active interest in finding good service. On the other hand, if a contractor gives you a hard time with these questions, you probably want to find someone else.
