Service Pros

    A.W. Viohl Contracting, LLC Logo
    Claymont, DE·

    "Andrew was terrific from our first meeting. I had a little drawing of the addition explaining what we wanted. He worked with us to create our ideas into an addition of bathroom, laundry, mudroom area and a screened in porch. He made suggestions which were very helpful and helped me look for a few different looks I wanted. If he wasn't on the job his crew was and they were great to work with as well and knowledgeable of the project to answer any questions. They were very professional, easy to work with and always reachable with a call or text. We have a beautiful addition and screened in porch that started with scribbles on paper. We would highly recommend Andrew and his team."

From start to finish, the project was a seamless and satisfying journey.

The team demonstrated exceptional efficiency and organization, ensuring that every milestone was met without compromising the quality of their work. In fact, they finished ahead of schedule. The workmanship and overall quality of the remodeling exceeded our expectations. Calahan Bath and Kitchen attention to detail was evident in every aspect of the project, from the selection of materials to the precision of the installation. Our master bathroom now reflects a perfect blend of functionality and aesthetic appeal, thanks to the craftsmanship displayed by the skilled professionals at Calahan. Throughout the remodeling process, the Calahan team proved to be not only proficient but also professional and courteous. They respected our home as if it were their own, maintaining a tidy work environment and minimizing disruptions to our daily routine. Their dedication to customer satisfaction was evident in their open communication and responsiveness to any questions or concerns that arose during the project and after completion. I highly recommend Calahan Bath and Kitchen for any remodeling projects based on my positive experience.

    "I was very impressed with the initial visit. Sam was very knowledgeable regarding what I wanted done in my powder room and laundry room. He guided me through the process ensuring that I had enough of what I had already purchased. He also was very patient and understanding with the subsequent questions I had. The installers also were very professional and answered the questions I had during the installation process. They did a wonderful job of cleaning up after the job was completed. I would recommend this company to anyone who needs to remodel their bathroom. I appreciate having a nice powder room that I can use now. Thank you."

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.
