"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."

"Just wanted to share how DiOrio Builders and Designers completely fixed a roofing issue that had been causing minor leaks for years, and grown worse in the past winter. These guys are elite yet ethical contractors, because they don’t shy away from getting to the root of the problem even if it turns out be labor intensive, or technical to fix. DiOrio Builders and Designers were willing to fully peel back the layers, do the detective work needed to find the issues, and they were honest with me about what needed to be done. I really appreciate that DiOrio didn’t try to skip steps or find a shortcut. All problems underneath the shingles are now fixed. They placed porch roof shingles on neatly, and the new shingles shine next to the older house roof! 5 out of five for this job!"

"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 needed plans for a two-car garage of a certain size and roof pitch. I could not find stock plans of specifically what I wanted. Richard was very prompt and helpful, produced the plans and arranged for an engineer's stamp."

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.
