    "I first hired Ariel Builders to install flooring in the master bedroom. I was very happy with the work, and so I hired them to completely remodel the master bathroom-- that also went very well. So I then hired them to completely remodel the guest bathroom-- that went very well. So I recently hired them to completely remodel the kitchen, and that project is being worked on now... The kitchen looks great-- I would recommend Tony, David, and his team, and if I need any other work I'll definitely call them."

    "Ben and Jona, Project Managers for SoCal, did a fantastic job! Their attention and care for details of my old 1924 home was greatly appreciated. The quality of the workmanship and the construction crew were kind and gentle while respecting the vibe of my quiet neighborhood. I would highly recommend SoCal to anyone looking to put on a new roof, install new gutters, install new air ducts, clean the attic, install new insulation, or do any other work on their home."

    "We used H&A My Design to 1) replace all flooring in our home with tile and laminate, level flooring in main room and hallway 2) move the washer dryer hook-ups in the laundry room, install proper draining and water line, etc. (this was a big job) and 3) basic bathroom remodel (tile and new vanity). The work was completed in a quality way, the tile in particular is beautiful and was laid with care. The work did take longer than anticipated, but that has been my experience every single time I have had any work done on my home with any company. We did identify some things that needed to be fixed after renovations were completed (splatter on walls, doors not closing well, pain in laundry room, etc.). While I would prefer everything be done right the first time Golan and Rony were good about coming back and making sure we were satisfied with final product. Overall experience was good, but removed one star for the reasons described above. You can probably find cheaper pricing, especially if you sub the work out... but we appreciated the convenience of a one stop shop GC."

    "As a new homeowner, I was at first concerned about hiring contractors for home improvements for my condo. Being a realtor myself, I'd heard some horror stories. However, this is why referrals are so very important; for my second window quote I was put in touch with Alex at Home 2 Renovate. From the original handshake, the thorough quotation and the hierarchy at the company providing samples to my HOA (for their approval) to the installation of the windows and sliding door, it was painless and stress-free for myself. The install itself was an eye opener; the guys worked fast & efficiently, and really knew what they were doing, even on my second story windows. Living close to Sunset Blvd, the first major benefit I noticed was the significant sound difference compared to my old windows, its simply amazing! They look great, I'm over the moon. In my line of work, I won't hesitate to recommend Alex and the team. Look forward to working with you more in the future, thanks guys!"

    "WOW! What can I say, if your in the market to get a garage remodel this is the company you want to hire! I made an appointment with them to come out and bid the job, Ron came out looked it over emailed me a bid a few days later, all though they weren't the cheapest bid I was impressed with Ron's professionalism and decided to go with them. From day one the guys Ron has working for him are first class! From the concrete guy to the framer and tile crew all are true professionals. In many construction projects you're just waiting for something to go south and turn into ww3 with the contractor....but it never did, I couldn't have asked for a smoother job from day one till the end of the project. Don't waste your time with other companies this is the one you want to hire! First Stop Construction!"

    Kitchen Remodels

    "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!"

    "Hiring the right Construction Company can be a bit of a challenge. I am so thankful that I found Blueprint Construction they are truly top notch. From the estimate and permit process, through the tear down, clean up, and roof install, their professionalism speaks volumes. They do impeccable work and we never had to worry about the job at hand. They were always on time and did exactly as promised. The job was quoted to be finished in about two days and it was. We had no problem paying their fees when the company's reputation and work ethic proves their value."

    "Green Planet Remodeling Inc. helped us with our kitchen remodeling project. We were very pleased with the entire experience. We have two infants, and Jonathan, the project lead, was very respectful of our space and needs. He kept noise and dust to a minimum, and communicated with us constantly to let us know what was happening and when. Jonathan even made sure that his workers respected our needs. Jonathan is a details guy, and takes pride in his work, which is obvious in the workmanship. He made adjustments when unexpected issues came up, and went out of his way to identify and help correct some issues that were not strictly in the scope of the work. Most importantly, we were very happy with the final product, and we would definitely hire Green Planet Remodeling Inc. again."

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.
