"I recently had the pleasure of working with Authority Plumbing, and I cannot recommend them highly enough. From the outset, they came to my home with a plan that demonstrated their deep understanding of plumbing challenges. Clayton, the technician assigned to my project, was exceptional. He took the time to listen to my concerns and opinions, making sure that I felt heard and valued. He explained each step, ensuring I was comfortable with the plan before proceeding. When a sub-contractor was brought on to streamline the process started making several errors, Clayton quickly took charge of the situation. They fixed these mistakes, alongside resolving my initial drainage issues, at no additional expense, was truly remarkable. The team demonstrated a genuine commitment to ensuring the work was completed to the highest standard. Thanks to their efforts, my plumbing issues have been resolved. I would not hesitate to recommend them to anyone in need of professional plumbing services."

"I recently had 4 windows replaced at my home, and the entire process was smooth and professional. The team arrived on time, worked efficiently, and made sure everything was installed properly and sealed tight. The new windows look great, have improved the comfort of our home, and we’ve already noticed better insulation. I’m very satisfied with the quality of the work and would definitely recommend them for any window replacement project."

"My project was to remodel the street-facing side of our house exterior and included (1) Demolition of existing wood and brick structures, (2) Plastering/stuccoing of a significant area on the house exterior and (3) Painting the whole exterior of the house. The demolition was accomplished in less than one day; the plastering/stuccoing required 3 days and the painting required 3 days. Juan Munos, the project leader was great to work with. He was very customer-oriented and went to great lengths to insure that we would be happy with the finished product. His workers were very talented, hardworking and punctual. He used different teams for the demolition, the plastering/stuccoing and the painting phases of the project with specialists in each pertinent area. His team did a great job of keeping the work-site clean and orderly. And very important, his prices were very competitive (we got 3 bids before we made our contractor selection.) I highly recommend Skyline Construction and will use them in the future."

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.
