    "I hired RNS to add a Master bedroom and remodeling on our new home. Emma and Yahav were the best match for our needs since the walked us through the process of designing, creating plans, pull permits and dealing with all the pre construction due diligence. During construction Emma and Yahav helped us make the decision we couldnâ t take our self and helped us sticking to the budget. I will definitely hire them for our future project and highly recommend working with RNS."

    "We are so happy for choosing Gettler Construction for our house remodel and addition. They not only do beautiful work, but they are good people you can trust. No matter what my request was, they made it happen, and always worked with me in my budget. Jason is a great at constant communication, and his crew was always willing to go above and beyond. When we first used Home Advisor to get bids, Gettler was comparable to others, yet his honesty and integrity stood out beyond the rest from the very first meeting. I am so glad we decided to choose him as our contractor. We had them build an upstairs Master Suite above our patio, as well as a mudroom and half bath, a full deck and outdoor kitchen. They also changed the framing of our porch and enlarged it. As well as refaced the entire house with siding and stonework, remodeled the existing kitchen fireplace and bathroom, added HVAC, and fencing. They truly made our house the best looking house in the block, everyday a neighbor gives us compliments on how good it looks. They work hard and wonâ t stop until you are happy, and they literally can do anything. I appreciate Gettler Construction everyday, for turning my home into my dream home and I give them the highest recommendation I can."

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.
