We had such a fantastic experience with Kevin during the construction of our screen porch. He is perhaps the best contractor we've ever worked with.

We would highly recommend KMS Systems, Inc. to anyone!Posted onTrustindex verifies that the original source of the review is Google. KMS Systems just completed the second home renovation project for us in the past three years. Not only did they meet each challenge, but they far exceeded our expectations by providing our 60-year-old home with a fresh and contemporary look, all within our budget. The owner and contractor, Kevin Fitzgerald, brings a rare blend of engineering expertise and superior communication skills. He provided us with numerous renovation ideas and suggestions while constantly keeping us informed of construction timelines and updates. He directs a team of talented project managers and skilled craftsmen, all committed to a high standard of professionalism. Superior quality, customer care, and exceptional performance are hallmarks of KMS Systems. I would highly recommend their services!Posted onTrustindex verifies that the original source of the review is Google. KMS build my patio/porch cover. They did an excellent job and the finished p[roduct is high quality. They paid careful attention to the facia of my house and handled the rain run-off. Despite speed bumps from city permitting, and a required new survey of the property; they patiently helped through every step of the project. I would strongly recommend them for anyone looking for permanent, outdoor patio covering.Posted onTrustindex verifies that the original source of the review is Google. We had 9 windows replaced at our house (original to the home) and the team had replaced them with the Reflection Series windows from Simontek within 1 business day. The order did take 13 weeks due to manufacturing issues related to Covid, but we were more than fine with that wait as some others were waiting 19-24 weeks. The team perfectly caulked and sealed the windows, and were very friendly during the installation! Would highly recommend using KMS Systems, Inc. for your house needs in Jacksonville Florida!Posted onTrustindex verifies that the original source of the review is Google. KMS re-sided my home with Hardie board and did a great job. Kevin answered every question, fixed every little thing that came up and personally did the final cleanup and walk through. He was always available, responsive, professional and easy to deal with. His crews knew their jobs and performed them well. The best experience I have had with a contractor on a sizeable job.Posted onTrustindex verifies that the original source of the review is Google. KMS Systems enclosed our porch. They did a great job!
