"I had rotting wood around my sliding glass door sill. After coming right out and assessing it, I was given a written quote withing a day. Everything was explained to me by phone. After me deposit, the project was started in little over a week. The workers presented well, were polite, and kept to task. I was kept appraised of their progress with pictures and videos of what they how found( a leaky aur conditioner near the door). All the rotting wood was removed as well as the mold. Everything was cleaned up nicely at the end of the day. The same crew was back at it the next day. The work was exceptional. Again I was kept appraised of their progress. The project was finished and another clean up was done very well."

"We hired James, Dan, and their crew for a major deck renovation. The level of thoughtfulness and craftsmanship throughout the project was outstanding. This was not a simple refresh — it involved removing an existing hot tub, renovating a cabana, reworking the deck framing to convert it into a single-level deck, installing a new staircase, and adding a cable rail system. Every aspect of the project was approached with precision and care, and the finished product is without flaw. They were easy to work with from start to finish, handling decisions and mid-project modifications thoughtfully and professionally. The whole crew was consistently approachable and friendly, and clearly took pride in their work. Daily cleanup was always done well, which we especially appreciated since we had a puppy at the time. Definitely recommended!"

"Erick is a truly good man who stands by his word/price. I had two bathrooms remodeled and I am thrilled with the end result. Erick made sure that any inconvenience to my family was minimal and at the end of every day their clean up incredible. After getting three other estimates, I had Erick come over to estimate the price and his price was 20% lower than some of the other estimates. Erick is my go to contractor, I trust him and I intend to have him do some more work this spring. Feel safe hiring Erick, you will not be sorry."

"We hired LionHeart Finish Carpentry for an interior painting project, and we are very happy with the results. Gustavo and his crew were punctual, respectful, and careful with our home. They protected the floors and furniture, fixed small imperfections before painting, and left the rooms looking fresh and professionally finished. The quality of the work made a big difference in the appearance of the house. We would definitely use them again."

"I ACCIDENTALLY FOUND HOME ADVISORS WHILE HAVING LUNCH IN A LOCAL RESTAURANT. ROSS CONSTRUCTION CALLED, ON A SATURDAY, WITHIN FIVE MINUTES AND MET ME AT THE RESTAURANT IN TEN MINUTES. THEY HAVE COMLETED SEVERAL PROJECTS FOR ME HIGHLY PROFESSIONALLY (WHICH IS NOT MY PAST EXPEREIENCE) QUICKLY, HIGH QUALITY, AND COST EFFICIENT. IF I HAD SOMETHING TO IMPROVE, IT WOULD BE THEY NEED A COUPLE MORE SUBS THAT MEET THEIR HIGH STANDARDS. I HAVE HAD MORE THAN TEN AWFUL CONTRACTORS AND DEFINITELY FEEL I HAVE HIT THE JACKPOT IN ROSS CONSTRUCTION."

"To be fully honest, at first I was a little skeptical, as I am with most contractors, but they came in on time, were very clean, and were punctual about the things I asked for and needed done. The crew was efficient and the work was done correctly. They even helped and built my elderly neighbor a garage bathroom after seeing the work at my house. I definitely will have them back to build my ADU for my in-laws."

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.
