    "My experience with American home Improvement (crew and supervisor) was excellent. I purchased my home not a long time ago and I wanted to update some parts of it and to make it more functional and useful. Unfortunately my house needed so many things to be remodeled mainly to the living room and the kitchen. After a lot of research and hesitations I decided to contact American Home Improvement and ask them to come over and give me a quote. I met with Elad and my first impression was that he can deliver the project. The price that I got for the work (Kitchen: which included all new cabinets, counter tops, paint -- bedroom: paint, new carpet, fix the closet and install new crown moldings all around) was reasonable so I decided to give them the job. Now when my project is complete, I can say that I am happy and very pleased with the final results of this work. American Home Improvement completely remodeled my bedroom and kitchen. The work they did was extremely high and good quality and every time I have guests over I receive a new compliment at how great everything looks! Thanks again for all of the help American Home Improvement Team!"

    "Built Corp Group did a few remodeling jobs that were combines into 1 large remodeling project for us and we are very proud with the work they did. The remodeling project ended up with a complete remodeling of the main first floor of our house (kitchen, 1.5 bathrooms, bedroom, entry, living room etc.). The project required a lot of attention to all the details because it contained also the removal of a wall in the kitchen that gave us an open space and at the same time enlarged the overall space of the kitchen. The kitchen cabinets were all custom made and with all the new appliances... The new kitchen is no less than a gorgeous one! The project was on a daily basis and each day all the workers were at our house from morning to evening while supervised by Sam. we are very proud at our new house and we highly recommend them for any remodeling project."

    "The Vinyl flooring looks amazing in our home!!! We are absolutely pleased with the work that was put into this. It took Evergreen Construction team two full days and half a day to install about 800 sq. ft. of vinyl flooring and new baseboards in the living room, laundry, kitchen, guest bathroom, and hallways. From start to finish, our rep, Gabriel, communicated with us and his team to ensure this project would be completed in a timely manner because he knew we needed this to be done quickly so we could move in. Gabriel was helpful throughout this entire experience and we couldn't be more pleased with his knowledge and consultation. We definitely recommend Evergreen Construction Group for anyone in the market who wants new flooring."

    Additions and Remodels

    "We had the pleasure of collaborating with the remarkable team at Homescapes Design and Construction for a comprehensive renovation project in our home. This involved transforming a den space into a new bedroom/office with a full bathroom, reimagining our living room to create an open floor plan, and updating the electrical system throughout the entire house. Our project commenced in January of this year, and we were able to move back into our revamped home in June, with the project being fully completed in July. Angelito, our dedicated project manager, played a pivotal role in ensuring the project's success. We scheduled weekly meetings with Angelito to discuss and review the progress made. Although the project encountered a few setbacks and challenges that caused a slight delay, Angelito consistently went above and beyond to work with us and find solutions that met our satisfaction. His availability and responsiveness were unparalleled, always promptly addressing our concerns or inquiries through text, phone calls, or emails. Angelito ensured that we were informed of any updates or issues that required our attention, allowing us to stay involved in the process. Upon the project's completion, my wife and I were thrilled with the outcome. Stepping into our home now feels like entering a brand new space, as the transformation is truly remarkable. While we did encounter a few bumps along the way, we are now enjoying the comfort and beauty of our revamped home, thanks to the incredibly positive experience we had with Angelito and the entire Homescapes Design and Construction team. If you are considering renovating or remodeling your home or property, we wholeheartedly recommend reaching out to Homescapes Design and Construction. Their expertise, professionalism, and commitment to delivering exceptional results make them an outstanding choice for any renovation project."

    "Avi and his team were fabulous. At the beginning of the process, he was the only contractor that we had spoken to that even mentioned the abatement process and how it might affect us. He was personable and friendly and made sure our need to live in the house during renovation was addressed. He stopped by regularly and had chats with us making sure we were happy with the process. Avi made sure that we knew that something might not be the best idea but if we truly wanted it he would do it. We did the kitchen, the master bedroom, master bathroom, guest bathroom, all windows, all doors including the front and garage doors. It was a huge undertaking but what a transformation. We were first time home remodelers and they walked us through every aspect of the process. When the unexpected happened, they were up front and let us know. The construction team under Luis were fabulous. We would swear Luis was a magician, the kinds of things he could get done on the spot were amazing. Definitely a man of many skills. The crew were respectful and friendly. They made sure everything was clean and livable at the end of each day. Also Joyce, the office coordinator, was awesome and we had a text thread going with her and Avi the whole time. All the permits were obtained in the proper manner and everything was done according to safety regulations. We are thrilled with all of our new home and highly recommend Finesse Remodeling and Consulting for all your interior remodeling needs."

    "Home Pros Builders, Inc were fantastic. They remodeled one of our kitchen, living room, laundry room formal dinning room, installation of new kitchen cabinets and master bedroom. Simon was extremely helpful throughout the process. They were clear in communicating the whole process and all the pieces necessary. They taped off and protected the whole path leading to all rooms and made sure nothing in the house was damaged. They went above and beyond to complete work that was beyond the scope of the original project and made sure the place looked immaculate after it was finished. The contractor was there on schedule every day and I saw consistent progress throughout. I would use them again in a heartbeat!"

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.
