"We recently hired ARMs Home Improvement to fix a significant water leak in our bathroom which was also impacting our kitchen directly below. ARMs team quickly understood the problem and provided a very transparent estimate. In my case, the shower installed by the original builder needed to be addressed. I am very impressed with their professionalism and excellent craftsmanship. The team was respectful for our home and kept the workspace tidy every day. Their quality of work far exceeded our expectations and would highly recommend ARMs Home Improvement to anyone looking for a skilled, experienced and honest contractor. I finally found a team that I can trust and turn to for future repair and renovation needs!"

"Great experience working with Willis Builders and so happy with my updated bathroom. Tracy Willis was super supportive in helping with the design process while honoring my vision and Will and the crew did an amazing job putting it all together with meticulous attention to detail."

"Tommy and his team at Bent Palm did a fantastic job, giving my old deck of 22 years a much needed facelift with the Trex product and with black metal railing. The deck is just stunning !! I liked it sooo much, I also Tommy design and build a stone patio with a bench wall and fire pit. From the computer generated design to the final product (and the patio looks exactly like the illustration), another fantastic job! Well done Bent Palm. You get my 5 star rating!!"

"Omar and his team did an outstanding job painting my home. They were consistently professional and courteous, always arriving on time and communicating clearly throughout the project. The work was completed efficiently and with great attention to detail, leaving everything clean and beautifully finished. On top of that, their pricing was fair and transparent. I highly recomment Omar General Contracting for anyone looking for quality painting services."

"Tomas M from JW did a great job. Needed replacement for part of the frame of front door. He did a fantastic job in matching the replacement panel to the rest of door. He also painted the entire frame and replaced some additional wood that we damaged at top of frame and caulked it all. Also had a basement door frame sanded and repainted. He was very good at keeping me informed of the process."

"This is our fourth time using Diaz for our home renovations. He refinished and stained floors and painted several rooms. He also rebuilt an upstairs deck. In addition, he took care of about 10 other little things that needed fixing. As always, Diaz was the best contractor we’ve ever encountered. He came right out for a free estimate. He gave us constructive advice on the proposed work. His crew got started right away - they were reliable, on time, courteous, and cleaned up impeccably each day. Diaz stuck to his estimate. In addition to all these positive traits, one of the best things is that Diaz and his team can literally take care of anything. You will not have to rely on a subcontractor or having to call somebody else - he does painting, flooring, kitchens, doors/windows, drywall work, tiling, bathrooms, etc. He even has his own tree guy and electrician for when those things come up. He doesn’t just do everything, but everything is done to perfection. Highly recommended!"

"Best Homes LLC just finished our basement and we could not be happier! The quality of work is outstanding and the team was always on time, happy to be here and great at communicating. Jefry is a great project manager and always takes your input regarding placement of different aspects and fixtures. It was a lot of fun working through picking out different tiles, flooring, cabinets, colors, etc to make the space how we envisioned it. We even got to choose the placement of extra outlets and things to make the space fit for our use. The price was very reasonable, especially after being quoted nearly double from another contractor. Our basement turned out absolutely gorgeous and now we have a functional, finished space with a full bathroom and wet bar included. The team was incredibly accommodating, gave a generous allowance for tile and flooring, etc. The project was finished with the quoted price and on time, and we will use Best Homes LLC as our go-to for any contracting needs. 10/10!"

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.
