    "A2Z Contractors helped me change the layout of an existing house extension and connect it to an unfinished lower level. A living room/kitchen combo became a bedroom and the new home of a laundry area. They installed a stairs to the lower level and finished the space by installing drywall, insulation, interior and exterior door, support beam and windows. They work started late December with a planned completion by February at the latest and they were completed by then. I was impressed that they stuck to the timeframe; and their professionalism and communication skills. Iâ ve already called on them for other asks and will continue to do so.

    "Hi. I am a baby boomer so I wanted to direct this towards others my age. I want to outline how wonderful my experience was with Usin from Custom Build and Remodeling llc. He was prompt and professional. Our first conversation was Sunday evening and he and four other employees were ripping out my bathroom completely on Wednesday morning. They showed up at 8:00 sharp every morning and worked till 4:00 each day. We had some extra issues in the 65-year-old house that Usin handled professionally with complete communication. They cleaned up thoroughly after each day and there was not one time within this entire project that I felt insecure. That’s a huge bonus! I am thrilled with the way the bathroom came out. A leaking vent pipe and wiring concerns led to problems above the bathroom in the attic. I was completely aware that my roof was shot so we agreed it should be done now. Roof, gutters and a house paint all done within the same timeframe. Highly recommend!! Serious professionals!!"

    "This was quite a project - both my porch enclosed and a bay window replaced; I had very high expectations and I am very particular. Past project experiences with other companies were horrific, so to say I was skeptical at the best is t put it mildly. Upon completion of both projects, I am beyond pleased- they look BEAUTIFUL! Workers were timely, polite, thorough. A particular praise for Dolores Martino- she was my constant contact person; always available, always polite, always patient.: in times where customer service is severely lacking, she shines bright. Project manager Chris was also wonderful - both of them always made me like my satisfaction was priority. This was truly a wonderful experience."

Ilir really takes the time to talk to you about the details of the project and made an extra effort to come by when the railing company was also at my house. He inspires a lot of confidence as he seems to be very experienced and knowledgeable and have great ideas and excellent judgment.

    "I highly recommend DDR. There are so many contractors out there and it is difficult to know what youâ ll get when you hire someone, from the quality of the work to the level of communication. This team did a great job from start to finish, and delivered a beautiful new space for my family. We selected DDR after getting multiple bids to update our walk-out basement into a more livable space. Key in this selection -- the price was competitive, and the team seemed attentive to the project needs as outlined. I had a tight budget and relatively aggressive timeline for this project. Admittedly the timeline was impacted by a few things that were out of DDRâ s control, including the Town building inspectorâ s schedule and a delivery delay (a new window arrived damaged and had to be reordered.) Nevertheless, the team stayed on budget and delivered a wonderful new basement. What a great project team -- led by Alex, the team (including John + Angel) truly transformed a dark dingy space into a bright fresh room. Alex was very thoughtful in suggesting options that would improve things and was exceptionally attentive to detail. He was super responsive to any texts or questions. In particular, I appreciated his high level of â perfectionismâ in how the finished product turned out. For phase 2, we need some custom cabinetry built for the space and I look forward to having the DDR team return to work on this next phase."

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.
