    "We hired H&A to for a pretty large project in our home which included 3 bathrooms, a full master suite renovation from top to bottom, a new laundry room, fireplace refacing, and new door installations. It was a very expensive investment for us and we needed to be very careful with the company we chose to work with. H&A delivered all around! They finished on time, were clean and neat, and delivered beautiful results. We are thrilled with how our home looks! Another important thing to note is that when we did hit bumps or we weren't happy with something, they were very quick to resolve the issue and never pushed back. They want you to be happy and will do what they have to in order to make sure you are completely satisfied. No project is without some bumps, so you need people who know how to deal with issues effectively and they do. Eran was out Project Manager and he was an absolute pleasure to work with!"

    Additions and Remodels

    "Having Angilito as our project manager was a true blessing. Our home remodeling project had been meticulously planned for a long time. We were inspired by the beautiful results of Homescapes Design and Construction's work on our close friend's home addition. During a walk-through of their project, we had the pleasure of meeting Angilito, who was their project manager at the time. It was an instant connection, and we knew right then and there that we wanted to collaborate with Angilito and Homescapes Design and Construction. We entrusted them with our entire project, including design and architecture services. Our remodel involved structural changes, for which Jamie, the company's architect, provided invaluable assistance. From planning to the permit stage, the process went smoothly, despite challenges in communication with the city. Thanks to the team at Homescapes Design and Construction, everything stayed on schedule. Angilito proved to be an exceptional asset, displaying patience and firmness in dealings with vendors and remodeling professionals. He attended to every intricate detail, ensuring that the project progressed according to plan. The city inspector was impressed by the team's organization and attention to detail, acknowledging their professionalism. Choosing Homescapes Design and Construction was a decision we do not regret. We felt secure in their capable hands and trusted them to deliver quality work. We extend our gratitude to the rest of the remodeling team, whose respectfulness and assistance were greatly appreciated throughout the process."

    "I am totally thrilled with my newly renovated bathroom! Barak Builders did an incredible job completely transforming the space. I especially love the handheld shower next to the new bench, the pocket door, the adjustable lights, and the double sink vanity. The team helped me come up with an amazing design and select beautiful materials, and the end result is even better than I imagined. The workers were super professional and clearly took a lot of pride in their work. A big thank you to Shai and the whole Barak Builders team!"

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.
