"They did a wonderful job, and I could not have been happier, with the work they did and how easy they were to deal with."

"I contacted Gary after being referred by HomeAdvisor. I was looking to get an estimate on some foundation work. It ended up that I did not need the foundational work at this time, but then the storm caused me to have some roofing damage. Because of Gary professionalism and quick response previously, I contacted him immediately to see if he could help me with my roofing needs. He was quick to respond in giving me an estimate and got the work done quickly as we were concerned about any further damage from the impending rain. I would definitely hire him again! They did a great job. I highly recommend them."

"Eddie was great to work with! We had a limited time frame to adhere to town inspections and Eddie and his team knew exactly what we needed and quickly got the job done. The results were great and even the inspector acknowledged the impressive repair. They were able to put a knocked out garage wall back on the foundation and repair the interior dry wall. I would recommend this company for any professional contract work due to their reasonable price, ease to work with and quality of work."

"I hired Tanem Construction to remodel my bathroom in April 2026. They were professional from start to finish. Mike provided a detailed estimate, and the team arrived on time every day. They were careful to protect my floors and cleaned up thoroughly at the end of every day. The work was completed on budget, and the tile work is exceptional. Mike offered valuable suggestions that improved the final outcome. Highly recommend! Truly a five-star experience!!!"

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.
