    "Memo renovated my apartment and I couldn’t ask for anything better. All the rooms he did, kitchen, bathroom, bedroom, and living room are absolutely perfect and I would highly recommend him."

    "We had an excellent experience working with AJC Homes on our bathroom remodels. Joseph was truly wonderful to work with, and honestly, with everything going on in our lives this year, I really appreciated how much I could trust him to take care of everything. That peace of mind meant more than I can express. The work itself is beautiful. The craftsmanship is clean, the design is thoughtful and functional, and the entire process felt easy and non-invasive, which is rare with home renovations. We completely gutted and remodeled two upstairs bathrooms and relocated our laundry units upstairs, and the bathrooms are now my favorite rooms in the house. Pricing was tremendously fair and transparent, communication was clear throughout, and the end result exceeded our expectations. We are incredibly grateful to Joseph and the entire AJC team and fully intend to call them again when we are ready for future projects. I could not be happier with how everything went. Highly recommend!"

    "Classic Home Design did my kitchen remodel, captured my idea and vision of what I liked and offered solutions for tricky spaces that I never thought would be very useful when you do all your kitchen work. After the job was finished, beautiful photos were featured in the House magazine and proudly showed them to my friends.. Not only that, I decided to improve the dining room. Classic designed for me a cathedral ceiling with all the curves and molding. It feels you are dining in a big home but essentially Classic had designed for me specific details of how a great living could be without spending a lot and satisfies how elegant you want to look like. After 6 months or so, I engaged Classic to do my driveway. I was impressed by their commitment to going an extra mile. The work included nice pavers, garden walls and stones nicely laid out in circles at the center, and provided a design for center landscaping. I am the only one in our block that has that kind of a nice rotunda design"

    "We hired ANDATE Construction to remodel the second floor of our home. It would be one thing to say that we are satisfied with the quality of work provided by Dan and his crew at ANDATE, but these guys deserve much better than that. Chris, who seemed to be the Project Manager on site, made sure everything went smoothly day-to-day and was extremely helpful anytime we had questions or concerns - this guy really knows his stuff. Every member of the crew were relentless in their work ethic. My wife and I were astonished by the amount of progress after each day. Bottom line is that: 1. The quality of work was outstanding. 2. The cost of services was reasonable and fair. 3. Each one of the guys that worked on the job were professionals in their crafts. 4. These guys show up when they say they're going to be there and the job is finished on time. ANDATE is not only a company that I'd be confident in recommending to anyone, but I'd also like to add that I'm looking forward to hiring Dan and his guys again to remodel our entire first floor early next year. If your planning some renovations, give Dan at ANDATE a call - you'll be very happy you did."

    "My wife and I purchased a beautiful 4 bedroom/4 bathroom house that Jakob and his team built on Long Island! We love the design of the home and Jakob was very friendly and responsive throughout the entire process. He was also very open to our feedback and suggestions and included blinds on all the windows, and medicine cabinets and towel bars in the guest bathrooms post-construction. Jakob didn’t cut any corners, as the home is very well insulated and includes state of the art appliances. He has also been responsive to us post-closing and we hope we can continue to maintain a friendship with him in the future. We highly recommend him and his team!"

    "Eddie was great to work with! We had a limited time frame to adhere to town inspections and Eddie and his team knew exactly what we needed and quickly got the job done. The results were great and even the inspector acknowledged the impressive repair. They were able to put a knocked out garage wall back on the foundation and repair the interior dry wall. I would recommend this company for any professional contract work due to their reasonable price, ease to work with and quality of work."

    "Gerard (aka Promaster Maintenance Corp) and his crew did a fantastic job on my really long driveway. They laid over 1,700 square feet of asphalt. They reset the existing Belgium blocks and cemented them in place in a perfect straight line and the Belgium blocks on the front of the driveway has already received raves from our neighbors. His crew is polite, hard working and they did a good clean up job after every work session. Gerard was determined to make us happy and made every adjustment we requested. He offers his professional opinion to make the job right. His pricing is competitive and there were no â hiddenâ surprise charges. Would I hire Gerard and his team again â YES."

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.
