    "Really great experience after hiring Platinum! We had a great experience when we started to get their help regarding kitchen renovation. At first, I was very afraid with the thought of a time consuming and difficult process of kitchen remodeling. However, the project manager resolved all my concerns with the matter. This company has some mind blowing ideas and thus gave me a beautiful kitchen within very short period of time. I will always be grateful to them for their excellent services."

    "We got introduced to M.DH. by friends who had beautiful work done at their house. We bought a house in Tarzana that requires renovations in several parts of the house and right away in our first meeting with David we felt confident we were not only hiring an expert but someone who has pride in what he does and can be trusted. My husband and I don’t always align and David just steered us in the right direction and away from was wastful projects. David made surebwe had the best line-up of professionals — from electricians, plumbers, and painters to countertop fabricators. It was like a seamless supply chain of teams taking over from each other. And Lia who was in charge of the back office was communicative and flexible when we had to mive things around our schedule. The projects were seamlessly executed and on time and budget. But what made the difference is just the personal way they dealt with us. Construction is always disruptive and stressful but they made it so easy!"

    "The work went fast and quicker than planned. A very efficient crew showed up the first day and did preparation work. This consisted of moving furniture, laying paper covering on the floor, covering all furniture in the center of the room with plastic and taping everything so that it was secure. They even had time to start painting. Work continued through the second day and was completed the third day ahead of schedule. The crew then cleaned up the coverings and moved all the furniture back into place. The painters were professional and hard working. I am very pleased with the outcome. I recommend the use of KN Remodeling to everyone."

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.
