"I hired Near Me Roofing Company to replace my Siding, shingle my roof, replace a rubber roof, and replace my gutters plus new . Everyone I dealt with was professional, courteous, responsive and knowledgeable. I am pleased with the work they had done. All was done in a timely manner and they cleaned all the debris and removed it. Near Me Roofing Company were wonderful and went out of their way to explain the work as well as following up with me.

"Vic turned a flood nightmare into a home we love. Our house flooded while we were out of town and we spent almost a year fighting insurance, only to get sent a list of their 1 star contractors. Then I found Vic and from our first call I knew he was our guy. He was always on time, kept us in the loop and got right to work. Most of all he's trustworthy. We were living in a hotel and never once worried about our house. His whole crew was great too, especially our super nice flooring guy. We went with every design choice he suggested because he has a great eye and no corners were cut. We moved back in when my fiancée was 6 months pregnant and were blown away. He stuck with us patiently even when we were going crazy. He even got us a baby shower gift and we truly see him as family now. We'll recommend Johnson and Sons to everyone. Thank you Vic!"

"I hired MMR to help me assess general repair work on a rental house. They were very communicative, flexible, and clear about which repairs were most important and which could wait. I ended up hiring them for a full exterior paint job and some bathroom work. In the quality of the work they went above & beyond my expectations, even making additional fixes beyond what we'd initially discussed. Very easy to work with, and got the work done quickly. Highly recommended!"

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.
