"Had an existing enclosed porch renovated. While reconstructing, had a few minor underlying issues that Derek and Joel, the two main persons on site, maintained professionalism; knowledgeable; and genuine with their craft. They provided an educational insight and how to remedy without 'gauging' the customer. Bill, Derek, and Joel very personable and looking out for the customer and then some. Highly recommend!"

"We are absolutely delighted with how everything came together. All of the staff from sales to management to the deconstruction, construction & tiling crew. The basement is beautiful so well lit and clean with a new floor, the kitchen floor and wall looks great the downstairs bath had a pipe burst through ceiling and it looks better than before everything was done with care. They also repaired wiring and plumbing. The upstairs bathroom was completely redone, it went from very outdated with a bathtub, old blue tile walls. It was so beautiful now the shower is big and luxurious. The tiles on the shower walls and wall behind sink are beautiful and the floor tiles tie in so well together, I was actually surprised just how well. I also needed a light in my closet and new updated kitchen pendant light to replace something that looked like it should be over a pool table. I am unfortunately unable to upload anything because my pics are over . MB. Everything is perfect we are so happy."

"TNN managed our new construction and land development project from scratch. Tim caught MANY errors by the Engineer and Architect before they could become a problem. He made many great suggestions to elevate our original plans. Work quality is great and they take pride in everything they do. Nick did an amazing job on our trapezoid windows and carpentry work. We highly reccommed TNN and will continue to use them for the next phase of our project (garage) We would be happy to provide a reference and even show the work they completed for our project.

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.
