"Rick White at Bradford construction really delivered for us in replacing an old sliding glass door in our new home. We'd placed an order for a new door with a big box store. After several weeks, it arrived damaged and we decided to seek new options. We found Bradford Construction on Angi and could not be more satisfied. Rick sourced a new door for us within a similar price range and kept us up-to-date and informed throughout the process.. Honest, professional, on-time and the team did a great installation job. We plan on working with Bradford Construction again and highly recommend them."

"Worked with me when the $50 a gallon "covers in one coat" paint took 3 to five coats. It was like he had to paint 3 houses not my small one. He's a highly experienced painter who "cuts-in" all the edges explaining that masking tape is for amateurs. A perfectionist in the art of painting! All ready hired him for 3 more projects!!"

"We had 6 different contractors bid on our deck/porch & siding project, and Russell's was a clear standout right from the start. This was a sizeable project for us, and even though Russell's wasn't the cheapest quote we received, project manager Keith did something that completely set them apart: He simply stayed in touch. From start to finish, Keith was communicative, responsive and always made himself available. He listened to us, kept detailed documentation, and made us feel comfortable every step of the way. In just a few short weeks, lead carpenter Todd & his talented team completely transformed our home. Thoughout the process they were friendly, respectful, professional & attentive to every last detail. We are thrilled with the quality of their work, and we couldn't be happier with our decision to work with this company."

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.
