"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!"

"Francisco Garcia did an excellent job finishing our basement. The work quality is excellent. The communication and flexibility throughout the project was excellent. The project finished on time within budget with zero surprises. Any concerns that arose were addressed expeditiously and professionally. I highly recommend Colorado Paradise Builders for your next project. The building inspections were coordinated by Colorado Paradise Builders and passed easily. We learned while talking to the inspectors that we had a gift by using Francisco as a general contractor. They mentioned other people in the business may not provide the level of customer service and professionalism which Colorado Paradise Builders demonstrated on our basement finishing project. I could not be more enthusiastic with a recommendation."
