    "Alex did an absolutely incredible job remodeling my bathroom. From start to finish, his attention to detail was beyond impressive. Every tile is perfectly aligned, the finishes are clean and precise, and you can truly see the care he puts into his work. He took the time to make sure everything was done right — not rushed — and it shows in the final result. The trim work, grout lines, fixtures, and overall layout were handled with such precision. He kept the workspace clean and communicated clearly throughout the entire process. If you’re looking for someone who genuinely cares about craftsmanship and quality, Alex is the one to call. I couldn’t be happier with how my bathroom turned out!"

    "We hired Brennan and his company when he first started his company, years ago. We had to structurally change the living room and dining room prior to renovating the kitchen. By the end of the project we had an entire open concept first floor, and brand new kitchen. Between the workmanship, communication, dedication to show up on time, when they said they would, I would highly reccomend B LaGrassa Construction."

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.
