"When we hired Brian and his team to remodel our house, we were so pleasantly surprised at the quality of workmanship, professional attitude, and level of work ethic. They showed up everyday, on time, & didn't quit until the job was done. He painted the interior of our home, fixed & painted all of our doors, ripped out old flooring & installed new flooring, installed new baseboards along with other smaller projects. They are able to handle everything. It is so great walking into our home now. There isn't any project they can't handle. Prior to this remodel, they power-washed the outside of our home, fixed some damage to our siding, and fixed a leak in our roof. They also replaced some drywall in our foyer that was damaged by a leak. Brian's entire team worked so hard and offered very valuable advice when I wasn't sure what direction to go. I'm already working on another list of projects for them. I can't recommend them enough.Their prices are extremely reasonable. They can do it all, I promise!"

"The team that did the work on our deck was responsive and responsible. Having small children we wanted our deck to be a place where we could spend time and not worry about the sturdiness of it and they delivered. Since it was built three years ago we have gotten many compliments on it. Great work"

"After absolutely destroying my bathroom thinking oh a renovations easy… I found Mason and he made it better than I could’ve imagined. He did the bathroom top to bottom! Drywall, bathtub, toilet, tile on the walls and the floor, the vanity installation and the light fixture! He even put the mirror and shelves up for me! Ended up having him renovate my laundry room (which was also a full gut and redo). Told him what I wanted and he made it happen! Custom shelves and cabinet! Already have him hired to do my kitchen!! Definitely recommend using this company for your renovations."

"We can?t say enough great things about Power2Construction&Remodeling LLC!! They brought the vision of our forever home to reality and surpassed our expectations! This was a substantial two part project: transforming our garage into beautiful living space and adding on a new three car garage, accessible through our kitchen. (with the addition of a tornado shelter in the garage for my increasing storm anxiety!) The crew at power2 are the best: high-quality workmanship, professionalism, knowledge, dependability and honesty! They considered every detail and communicated with us every step of the way! Their choice in subcontractors was above par as well!"

"Overall good experience. Worked directly with the General Contractor, he was able to work around my schedule and ensure that all subs completed their work to our standard the first time! Upfront pricing, honest and provided flexibility in price. For example, I wanted to have my own painter. Additionally I purchased my own vanity and shower. He provided just a labor quote. Iâ ve already recommended to two friends!"

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:
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.
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.
