Diamond Bar, CA·
Detail, Quality, Customer Satisfaction
"I contracted New Life Construction Renovation for the remodeling of two bathrooms. Young Lee, the owner, made it one of the best experiences I've ever had. In the past, before I met Young, I had bad experiences with contractors and remodeling. Young was very respectful, pleasant, and had good communication skills, and the working crew was polite and worked diligently. During the remodeling, there were issues and changes, but they were my fault, and Young was patient and understanding of my mistakes. They were quickly resolved. Young's working team were professional and quickly corrected any mistakes they made, which rarely happened. They used quality materials at very reasonable cost and made sure I was satisfied and I had no complaints at the end. I highly recommend working with New Life Construction Renovation for any of those who are looking to renovate. I am very satisfied with the results of two bathrooms and have no complaints. Thank you so much to New Life Construction Renovation for the great work and being patient and working so hard! I will definitely work with them again for my next renovation."

"I recently had 4 windows replaced at my home, and the entire process was smooth and professional. The team arrived on time, worked efficiently, and made sure everything was installed properly and sealed tight. The new windows look great, have improved the comfort of our home, and we’ve already noticed better insulation. I’m very satisfied with the quality of the work and would definitely recommend them for any window replacement project."

"We had a difficult case that COVID made even more difficult to evaluate. After speaking with Eran, I was ready to grasp what I can do next. I would highly recommend calling ESL Designs for a virtual consult. Do not wait until COVID is over. Your home is everything. Do not risk permanent damage if you believe something is wrong. Discuss it with trained specialists who know what they are talking about."

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.
