"I hired King Kahn Construction to kick off my house remodel and couldnâ t be happier with the result. Justyn met with me multiple times to work through the various design changes I wanted and built my new finished basement. The work that they did was one of a kind and I am so happy I finally have my dream basement to entertain my family/friends and even added a new bedroom for guests. I am already in talks with them on remodeling the first floor of my house and canâ t wait to get started. They are one of the friendliest constructions crews out there and I actually learned a few things myself while going through the process. If anyone needs any work done on their house/business I highly recommend calling King Kahn Construction."

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:
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.
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.
