    "Alex did a great job on my small kitchen project of removing the cabinets/microwave and installing a hood. The time estimates were exactly as described and the work was done well."

    "Dave has done a couple projects for us and weâ ll hire him again when the need arises. He installed an attic fan that we never had before, cutting through our roof and ensuring the flashing and shingles were all in place to keep rain and moisture out. He walked us through the install so that we could operate the fan through our WiFi. He also repaired eves under our roofline that were heavily damaged from water and improper flashing from the original roof install. You would never know the work was done. The eves match the rest of the house and roofline perfectly. I mostly appreciate how much Dave explained what he was seeing and our options for each project. Heâ s a straight forward professional who cares about the quality of his work and that his customers are satisfied with their options and costs thereof."

    "We were very happy with Randy and his work. He did an excellent job and we couldn't be happier! Our job was a fairly large one, replacing carpet with new, finished in place hardwoods for almost 3700 sq feet. The job followed the timeline that Randy gave us ahead of time, as well as staying to the budget that he quoted us before the job started. When moving our furniture back into the house, a large object was dropped and it gouged our beautiful floors! I was devastated! I emailed Randy and Amber about it, and by the time I got home from work the next day, he had come over and fixed the scratch for us. That's what I call wonderful customer service! I would definitely recommend Rosell Hardwood."

    "I recently worked with Julius Remodeling Group on a second-story addition, and I couldnâ t be happier with the results. From the start, they took the time to understand my vision, offering suggestions to enhance the design while seamlessly blending the addition with the rest of my home. The 3D renderings gave me confidence in the plan, and the finished product exceeded my expectations. The team was professional, communicative, and always on schedule. They kept me updated throughout the process, addressing any challenges quickly and without added stress. The craftsmanship was outstandingâ every detail, from the structural work to the finishes, was done with precision. The new space feels like it was always part of the house, and Iâ ve gotten so many compliments from friends and neighbors. Julius Remodeling Group made a big project feel effortless, and I couldnâ t recommend them more highly!"

    "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."

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.
