Additions & Remodels, New Construction, Basement Finish
"I am very pleased with my kitchen remodel. They stayed on schedule and there were no cost overruns or other unexpected issues. Adam Parker built my parents' house back in 2006 so I knew the type of work he did, and he's bringing the same quality and workmanship to the remodels that he does."

"Hired Denver Construction to renovate the main level of my house including the kitchen and the bathroom upstairs and they did such an awesome job. 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!"

"Greg did an excellent job with our flooring and went above and beyond our expectations! Others came in and wanted to laminate over the existing laminate flooring in our kitchen. However, Greg did it the right way and removed 3 layers of laminate and was able to save our existing oak trim in the process. He was also very efficient when it came to using materials. I would absolutely recommend Greg for any flooring installation projects!"

"Christopher (Chris) can do any project. His estimate was the best out of three. He explains clearly what he will do. He puts it in writing. He did all the labor in the bathroom remodel, redirect plumbing, redirect wiring, installing the shower tiles and floor tiles. Helped us select our tiles, cabinets etc. He'll take you to stores to select tiles etc. He's very knowledgeable in selecting items that compliment the completed job. Easy to work with. He will become your friend."

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.
