Additions to Existing Structure, Custom Home Builder, Kitchen - Remodel
"At our first meeting, it was clear to me that John Hagenbach was a very honest and hardworking individual. His understanding of my goals and budget was exceptional and together we were able to map out the project to add a bay to our garage and to renovate and expand the apartment above our garage where our daughter, son-in-law and two young grandson's live. Having John and his crew at our home was more like having skilled family members working to insure we would have 100% satisfaction. They exceeded our expectations on every level including price, schedule and exceptional workmanship. It should also be said that this was accomplished during one of the severe weather we experienced this winter. FIVE STARS understates the performance of John and his team of craftsmen."

He did a wall of tile backsplash added two more interior outlets and interior lighting. He went to compare prices and was able to stay with in my price range. Professional from the start respectfully young man he kept job site clean. Very responsible if any changes he would contact me right away if needed an approval.

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.
