"Choosing them for my bathroom remodel was the best decision! They turned my cramped, outdated bathroom into a luxurious spa-like retreat. Iâ m especially impressed with the quality of the materials and how efficiently they worked to complete the job. The heated floors and modern vanity are my favorite features."

"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!"

"We highly recommend Creative Innovation Developers Inc. Ben is an honest, dependable business man who is great to work with. He does what he says he will do in a timely manner, stands behind his work and makes sure you are satisfied. He and his crew put in all new cabinets, flooring, counter-tops and new paint coat for our kitchen. Ben is a true asset to the company. I felt like we became friends during our remodeling. He kept in touch with me and updated me every step of the way. I have recommended Creative Innovation Developers Inc. to several of my friends and will continue to do so."

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.
