I can not stress enough how professional and knowledgeable this company is. I met with rich when I called to get an estimate of my crawl space told me exactly what I needed how I needed and very professional. Once that was established got in contact with Cathy who again was very professional and patient with the information they provided told me what time the crew would be there who would be there and what to expect. Then the crew, Carlos and his crew went above and beyond. So professional, very efficient, and Carlos answered all my questions and ensured me all work was going to be done and on time. And they delivered, all work was done as promised and my crawl space was done very well and I’m much more comfortable on the inside of my home. This company stands by their products and are always communicating with their customers. I am very happy with my service, and look forward to their yearly maintenance of my crawlspace. 5 stars all the way.

Due to living on the water, I needed a French drain system and sump pump to keep my basement dry & livable… Ended up doing laminate flooring and walling called “clean space” WOW, what a different in appearance!! I’m enormously happy with the intense journey of redoing my entire basement! It truly looks like a different house! Special shout out to Joe and to Chris when it came to all of the technicals & and advice! Their patience and attention to detail is unmatched. Both Joe and Chris were always available by phone to assist with questions and even came in person several times to check on the progress. Additionally, a major shout out to David and Mikey, who were efficient and professional; installing the flooring that looks perfect & even took an extra step to make the clean space (white wall) be more taut!! If nothing else, this company definitely wants to do the right thing by you!! Thanks so much David and Mikey - you guys nailed it!! This was a huge job and I am thrilled with the results.

We had a wonderful experience working with Healthy Basement Systems a year ago, and I would like to recognize the outstanding team who supported our project from start to finish. Our first impression of the company came from Jess Rotenberg, and it was an excellent one. He was professional, knowledgeable, and genuinely approachable. The introductory package and information booklet sent prior to his visit were extremely helpful—they gave us a clear overview of who we would be meeting and the innovative products and solutions the company offers. Jess truly became our spokesperson throughout the process. He was always available to answer questions or connect us with the right person, responding quickly and efficiently. Even while on vacation, he still managed to help us, which we deeply appreciated. His dedication and reliability made a huge difference in our overall experience. I would also like to recognize Sal, the project manager; Jose Cornejo and the contractor crew; David and Carlos from the wall restoration team. Their workmanship and attention to detail were excellent, and they did a great job. Additionally, Tim, the service manager, and Richard, the service technician, were both outstanding in communication. They were prompt, responsive, and supportive, ensuring everything was handled properly, with care, and in a timely fashion. Overall, this team went above and beyond to help with our basement project. Each person played an important role, and they truly deserve recognition for their hard work, professionalism, and commitment to customer satisfaction.

Dear Healthy Basement Systems Team, I am writing to express my high level of satisfaction regarding my recent experience with your company. I am very satisfied with the entire project and the quality of work provided. I want to specifically commend your design specialist, Rich, and production manager, Sal, for their excellent support. I also want to recognize the work crew—Carlos (Foreman), Mikey, John, and Oscar—who did an outstanding job remedying the prior issues I had with water penetrating into my basement. The team was professional throughout the process, explaining each phase of the work before they began. After each phase was completed, they took the time to show me the results and demonstrated exactly how the system works. I truly appreciated that everyone encouraged me to ask questions at every stage. It is clear that your staff is honest, qualified, and dedicated to doing quality work. Thank you for a great experience. Best regards, Brian Castles

From start to finish, my experience with Healthy Basement has been nothing short of extraordinary. What began as a simple basement project quickly became the space of my dreams—a warm, beautiful, and functional area where I can enjoy quality time with my family. This transformation was only possible because of the exceptional team who poured their heart, skill, and dedication into the job. Eric Robles – Foreman Extraordinaire Eric Robles, the foreman on my project, quickly became more than just a contractor—he became someone I could trust completely. His attention to detail, craftsmanship, and genuine passion for his work was evident every single day. Eric took his time to make sure every finish was flawless, advocating for me whenever a decision needed to be made. I could tell he truly cared about the end result as much as I did. Christian Robles – Tireless Worker with True Dedication Working alongside Eric was Christian Robles, whose work ethic blew me away. There were days he worked straight through lunch just to keep things on track. His commitment to making sure the job was done right was inspiring, and his efforts never went unnoticed. Chris Seager – The Project Manager Who Made the Impossible Possible If there’s one person who deserves endless praise, it’s Chris Seager. Chris didn’t just manage my project—he championed it. When I faced severe plumbing problems and was initially told nothing could be done, Chris refused to accept defeat. He personally called me, promised help within the hour, and sure enough, Mike from Tumminello Plumbing & Heating showed up and resolved the issue. That moment changed everything for my project. From that point on, Chris became not only my project manager but also a friend. He visited my home every single day to check in on progress, responded to messages no matter the day or time (even on Sunday afternoons!), and never made me feel like my questions or changes were a burden. Despite the pressure from my many modifications to the project, Chris always found a way to make it work. His customer service skills, problem-solving ability, and genuine care for my satisfaction are unmatched. I can say without hesitation: I have Chris to thank for making my dream space a reality. Mike from Tumminello Plumbing & Heating Mike’s quick arrival and expert work on my plumbing crisis was nothing short of heroic. He solved an issue that others had said was impossible, and his role in this transformation will never be forgotten. The Egress Window Installation Team Another standout part of the project was the egress window installation team. They worked hard, fast, and clean, leaving absolutely no damage and delivering a perfect result. Their professionalism and efficiency were top-notch. Dave – The Reliable Backup Foreman Dave, who stepped in at times as foreman, also deserves credit. He communicated clearly, kept me updated, and ensured the project continued to run smoothly whenever he was involved. Final Thoughts Healthy Basement didn’t just renovate my basement—they gave me a space I fall more in love with every single day. I will recommend them to everyone I know, and as I’ve already told Chris, I’ll be telling people to request him specifically—because I know he will make their dream come true just as he did mine. Thank you, Chris. Thank you, Eric. Thank you, Christian. Thank you, Mike. And thank you to every single person at Healthy Basement who made this project such a joy.
