"This is how contracting should be done! I will definitely be recommending Continuum to my friends and family. First, they treated me like a human with a brain. I wish that wasn't so unusual, but we all know it is. They responded to my questions with real answers and provided considered pros and cons so I could make informed decisions and didn't just tell me what they wanted to do. Second, the quality of the work was fantastic. All the lines are crisp. All the surfaces are perfect. I, of course, picked a fancy sink that had an unusual drain situation but the Continuum guys rolled with it and came up with a really cool solution that hides all the plumbing. Third, they are so neat and tidy! No dust tracked through the house, no junk stacked up on my porch. And they were super sweet to my dogs who seemed to always be underfoot. Their prices were in the mid-range of the estimates I got, but I picked Continuum because they bring both the engineering and the art, and if I'm paying for custom, I'd like it to look fantastic and know that it was well done. And they're really nice people. :) All around great experience. Thanks Geoff and Nate!"

"Noah and his crew worked fast and built exactly what I asked for! We wanted a covered space on our deck to enclose it for a catio, and they understood my vision perfectly. They even framed out a door with a secure latch so our cats cannot escape. We are DIYing the rest of the catio build, but if I need any more help on this or future projects, I wouldn't hesitate to hire Noah!"

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.
