    "Palm Construction did many projects for me: remodel bathroom, replace the roof, termite treatment, install of can lights, crown molding, skylight, and painting. The workers are very friendly and all talented. The quality of their work is excellent. The overseeing contractor for all my jobs was Omri. He understands quickly the scope of what you want done. He is organized, honest, and prompt at returning texts/calls. He has personal integrity, and just is a really nice guy. All of the people I met in the company connected to my projects, from owner to people doing the actual work - they were really delightful to meet and work with. I would highly recommend Palm Construction for any project!"

    "The team at Pure Home Remodeling did a fantastic job. We have completed two renovations with Pure Home Remodeling and the second one was just recently. They converted our existing master suite to an additional bedroom with walk-in closets, painted the hallway with addition of crown molding and remodeled the patio. In the patio, they did all the hard-scape (fire pit/table and BBQ area). The paperwork from the estimate all the way to the finish of the work, was organized in details and they finished the entire work with a minor delay. Most of the delays happened because there were several issues with the materials that we purchased and they were not in stock. Most project issues that were raised during the work, were handled professionally by our project manager, his team and subcontractors which helped tremendously in solving them quickly and efficiently. We can't be happier with this entire experience with them and mainly with the way this remodeling came out, because we know personally about bad cases where work was not done professionally OR they were abandon in the middle. We are very thankful that our remodeling project went like that."

    "Eli and the team have been amazing. They took on a massive project to make our home accessible for our kid who uses a wheelchair. They built an accessible bathroom, built ramps around the house and made sure the bathroom door was able to accommodate a wheelchair. They gave a visual lift to our house by redoing our floors, modernizing the fireplace and adding recessed lighting. It is worth mentioning that they delivered with VERY high quality and ON time as promised. I highly recommend Alon design and remodeling for your house project. And they did it all while always smiling and being positive - a quality hard to find in a contractor. You won't be disappointed working with them."

    "Had him rebuild an old patio cover in my yard. All we kept were the posts and two beams. Replaced all else. Came out very nice. Couple months later had him do some porch railing and window sill repairs on a rental house my mother owns. Nice work, very fair price. Will definitely use him again."

    Major Renovation - Multiple Rooms

    "MTM did a beautiful job on my recent remodel. They added a master bedroom suite and doubled the size of my living room. They also moved and updated the HVAC system, created a new huge closet off of the hallway, and roofed the entire house. The quality of the workmanship was beyond amazing. Michael was at our house every day to manage and inspect the work and deal with multiple inspections. Nancy was very helpful when working with me to do the best the design possible, and she also helped to select the best materials for the job. I still can't believe the entire project took only four months. My neighbor is doing the same type of remodel with a different builder, and their house has been under construction for 10 months so far. I figure it will take them over a year to do what I had done in four months. I would highly recommend working with MTM for your next remodeling job."

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.
