    "We had the pleasure of working with Creation 7 on our kitchen remodel. We loved working with Cameron, our Project Manager. From the beginning, Cameron was extremely easy to work with and was very organized. He clearly laid out the project plan and communicated with us daily on status of project and any dependencies where he needed our input. He is one of the main reasons we had such a good experience with Creation 7. One of the things we value most about the Creation 7 team is they committed to a timeline up front and delivered on it. We've heard many stories where projects get delayed for various reasons, but the Creation 7 team was able to meet the original deadline. This was extremely important in us choosing Creation 7. Another thing we really appreciate about the team is their flexibility. They consistently were able to work with us as the project was in-flight and was able to adapt and pivot regardless of circumstance. The team worked very hard and was very productive each day and we were able to communicate our requirements and needs in real-time and the team was able to accommodate them to the best of their ability. Overall, the team was very professional and great to be around and it was a positive experience and we are extremely happy with the result."

    Additions to Existing Structure, Custom Home Builder, Kitchen - Remodel

    "I hired Hagenbach Construction based on a referral from my cabinet vanity vendor who I've done business with 4 years prior. John, his wife Amy, and his crew were AWESOME and the finished bathrooms can easily make an HGTV remodel or magazine feature. They were far better than I ever imagined. I wish I can post some photos here, but hopefully, the finished bathrooms will grace his website. My project involved two bathroom remodels - a master and guest (and the only two in my single story home) over a period of 7-8 weeks. The master bathroom was a total demo of the existing 200 sq. ft. space, on a slab floor and what we believed had post tension cables. It was a complex project, in my opinion, and one I waited on the right contractor to help me with. John was meticulous in the planning of the work, review of my design, and in every aspect of the tricky construction. While I had an initial design from the cabinet vendor, John validated the measurements, size of vanity, walk-in shower, shower seat and niches, placement of the freestanding tub, canned lights and wall sconces, vents, the new pocket door and bathroom door, etc.. The floor tiles and shower tile accent were very intricate, utilizing basketweave floor tiles and a herringbone shower tile accent. They were installed perfectly. John personally laid the shower tile accent on a piece of plywood for me to see and finalize before installation. The wall and placement of the carrara marble subway tiles and chair rails were also carefully planned across the room, so that he can plan for where the cut pieces were going to be. On the 6' x 6' walk-in shower, he assisted in getting me the best neo-angle configuration, with the best 30" door placement. He also guided me in the options for best hot water availability. There is nothing I would change in these bathroom projects and John and his crew were hardworking, meticulous, conscientious about the remodel inconvenience and were always a pleasure to work with. They always showed up early or when they said they would. I would recommend John and Hagenbach Construction to anyone for any project. Contractors like him are a gem, and few and far between. It shows that he and his crew take pride in their work."

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.
