    Jane A. of Greeley, CO
  • The crew worked really hard, I have never seen such hard workers & they deserve a pay raise. They left the house spotless which was a real joy because that never happens. The crew was amazing!

    Christine L. of Greenwood Village, CO
  • I was blown away with Agustin and his crew. The guys worked extremely hard and were very professional. They seemed like they took a lot of pride in their job and truly cared about the home, they were not just content with getting a paycheck. Will highly recommend the company to friends and family.

    Byron V. of Lone Tree, CO

    Pam M. of Denver, CO

  • I needed a service appointment immediately, but could only fit today on my schedule. Casey was completely booked, but instead of her saying "too bad" she called the service guys until Mike was able to come out. She even rearranged her schedule to get him in. That's redefining service! Casey definitely deserves an award for her superior effort!

    Nancy L. of Denver, CO
  • Jacob Bass and Jose did a fantastic job bringing up and leveling off a portion of our driveway that sunk and had become a tripping hazard. They were professional, answered all my questions and even showed me how to seal additional cracks in the driveway, and even provided the sealant at no additional cost. This was much more cost effective rather then replacing the entire driveway. I recommended them to a neighbor who was driving by and would HIGHLY recommend them to anyone. WAY TO GO COMPLETE BASEMENT SYSTEMS!!!

    Lynda S. of Aurora, CO
  • I wish to call to your attention what a marvelous experience I enjoyed with Bill Richards. He is wonderful; courteous, friendly, thorough, informative, engaging and very responsive to questions and discussion points to clarify understanding. As you are aware, I have quite a situation and it was remarkable that in all the meetings I have had regarding this matter, my meeting with Bill was excellent and I was treated with abnormally great respect as compared to other meetings on this topic. Being female, I have only met males in this process. It is often challenging as it is not expected that I am the decision-maker or that I have thoughts on the subject. Not a problem with or for Bill, and yes, he is the only person who did not ask where why my husband was or when he might be around to make decisions and/or call with questions.

    You must know that Bill Richards is an excellent and knowledgeable representative of your firm. It is a joy to share what a positive experience it was to meet Bill. Thank you.

    Mary R. of Fort Collins, CO
  • Very courteous and helpful staff, the salesman knew his product and sold it well. The prompt return of calls and immediate installation date was what led me to Complete Basement Systems. Jose and his crew were wonderful!

    Wyndy B. of Denver, CO

    Nicole B. of Thornton, CO
  • The whole process was quick! The crew worked with me to arrive while I was at work-left key under front door mat - crew would come in & lock up when finished.

    Leveda M. of Thornton, CO

    Tim P. of Denver, CO
  • Yesterday, your company sent three extraordinary men to begin work on my project. Knowledgeable, friendly, and courteous, they worked non-stop throughout the day. They are clearly the face of your business and you can be very proud of each one of them. They deserve every accolade your company extends to their workers. Even the electrician, hired separately, could not believe that they had accomplished that amount of work in so few hours. He was very impressed, as were the neighbors (who were hoping that their houses could escape the inevitable!). Thank you!!!

    Janice P. of Denver, CO
  • Rick is great to work with. Your pricing is higher than competition but the workmanship and pride taken in your jobs has been worth the higher price point. Warranty is excellent too.

    Garrett J. of Broomfield, CO
  • For what was otherwise a miserable experience, your company was the one bright spot.

    Peggy F. of Denver, CO
  • Based on my past experience with your company and the proposed solution I have confidence that the recommendation will solve my foundation settling issue. You really do run a very professional organization. It's nice to be able to have a company like yours around. You do what you say and can communicate clearly, you keep tight schedules and don't waste time. Thank you very much for all that.

    James T. of Denver, CO
  • This note is to let you know how pleased I am with the results of the work Alejandro and his crew accomplished for me this week. Not only were the guys professional in the approach to their work but they were proactive in approaching the job with the best esthetic results. This is not the type of work one looks forward to but when it is done professionally with the least amount of mess and customer grief, believe me, it is much appreciated. Please give your guys a "WELL DONE" in my behalf.
