"We recently had our kitchen completely remodeled by Tomer, and we couldn't be happier with the results. From the initial design consultation to the final touches, Tomer was professional, attentive, and highly skilled. He did a fantastic job with our cabinets, countertops, and backsplash, transforming our outdated kitchen into a modern, functional, and beautiful space. His attention to detail and commitment to quality were evident in every aspect of the project. We are thoroughly impressed with Tomer's workmanship and would highly recommend him to anyone looking to renovate their kitchen in Denver. Thank you, Tomer, for making our kitchen dreams come true!"

Trusted them in my home while I had to work and came back to a job well done on multiple occasions. Highly recommend this company. Will be hiring again sometime in the future. Thanks DC!"

"Alan Gaul merged two back to back closets and turned it into s larger pantry. He removed and closed off the two existing doors and repositioned it on the kitchen side. He did an excellent job and made sure everything was perfect and cleaned up before he left. I highly recommend him."

"Brian was really easy and flexible to work with. It was easy to get a hold of him with questions and he'd let us know in advance if he'd be out of pocket. Our house was delayed due to supply chain and COVID issues but he did everything in the realm of his control to keep our schedule."

"We had CoBuilt remodel our kitchen and family room, and the results completely exceeded our expectations! From start to finish, their team was professional, communicative, and incredibly detail-oriented. The craftsmanship is top-notch—everything from the cabinetry to the finishes looks amazing. They took our vision and brought it to life in a way that feels both beautiful and functional. We now have a space that’s perfect for everyday living and entertaining. I highly recommend CoBuilt to anyone looking for high-quality remodeling work. We couldn’t be happier with how it all turned out!"

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.
