"Yes—Anthony absolutely got the job done right and efficiently. This was a complex deck project that required special permitting, coordination with an electrician, and integration with hot tub installers, and Anthony handled it with professionalism from start to finish. He went out of his way to secure a special contractor permit and was consistently communicative, proactive about potential issues, and clear about solutions. When other vendors were hesitant or negative, Anthony stayed focused and kept the project moving forward. He worked seamlessly with the electrician and hot tub team and was on site for the hot tub delivery, making the installation smooth and stress-free. The final product is beyond perfect—it’s exactly what we envisioned. High-end craftsmanship, exceptional value, and a true professional. I would recommend him without hesitation."

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.
