Additions and Remodels
"Stop your search now, you've found the contractor you should go with, you will not be disappointed! This is the second project I've had Ben and his team do at my house and they knocked it out of the park again. This time around they remodeled two bathrooms and put in a new hall closet. They were rock stars throughout the entire project. There wasn't a single time that any reasonable request I made was denied. This was a huge load off my shoulders when dealing with such permanent decisions that comes with bathroom remodels. They were very patient and understanding as I ran into several supply issues that were out of my control during the project as well. It's very obvious that he's had years of experience with construction. His attention to detail and his forethought allowed my wife and I to rest easy knowing that they would always be able to bring up potential issues as well as offer us solutions to issues that we were going to run into many steps down the line."

"I got new vinyl flooring for my kitchen and not only did it give my home the look that I want, but the process was incredibly smooth. Vince was very communicative and straightforward, and as someone who tends to be an stress-case with large projects like this, all of the information was cohesive. Thank you, highly recommend!"

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.
