"It was a pleasure doing business with these fine craftsmen from start to finish! The quality of their work was far beyond what I expected. I was so impressed with their work ethic and professionalism. They truly listened and were collaborative through the entire build. Each day they were on-site, they worked very hard and with a cheerful attitude as well! My new custom shed is exactly what I wanted and I would hire them again in a heartbeat."

"The work was excellent and the final product looks great. The day of the poor it started pouring down rain and yet they worked round it and made it come out well. I highly recommend their work."

"The construction process went extremely smoothly. The crew was professional, efficient, and kept an incredibly tidy worksite. They took the time to understand my vision for the addition and made helpful suggestions to optimize the design and layout. The craftsmanship of their work was outstanding - the new second story blends seamlessly with the original structure. Perhaps most impressive was how quickly they were able to complete the project. I was expecting the addition to take months, but Umbrella Bill LC had it done in just 10 weeks. This was a major time and cost savings for me."

"During the summer of 2024, we were looking to get our basement completely renovated and we are so lucky that we connected with Zach. Zach and his talented crew worked endlessly to achieve our vision for the space and get it done within an extremely fast timeline. The detail to attention, easy and seamless communication and the trust we had for his crew are among the many reasons we will always use Zach for our home projects."

Frequently asked questions
- It’s important that you verify their license is still in good standing. Also keep in mind that certain states or provinces don’t require licensing if the job is under a certain dollar amount.
- You can find a list of your state’s licensing requirements on the HomeAdvisor website. Before you get to work with the pro, make sure their qualifications are current and acceptable to you.
- It is always a good idea to get a copy of the pro’s insurance certificate for future records, and in case anything happens. This is a good way to feel more secure in your home project, and to weed out potential scammers.
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:
- Have you completed a job like this before?
- Do you have a list of references I can contact?
- When are you able to start the job?
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.
- How many years of experience do you have?
- What’s your permanent business address?
- Are you licensed to work in my area?
- When did you earn your business license?
- How do you handle warranty service complaints?
- Do you have worker’s compensation, property damage and personal liability insurance?
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.
