“Great work, but taking the time to write this review because of the exceptional level of communication from Mike and his team throughout the project and post the project when we've had questions about the windows or even other projects on our house. Mike's been available and a valued counsel as we navigate projects/budgets being first time home owners.”

“KCSI recently replace a couple windows, a patio sliding door, and another exterior door. Their work was excellent, they were so respectful and clean, and we're very pleased with the overall experience! Mike (one of the owners) was so kind and easy to work with. He never tried to sell us anything, but simply explained what they could do and answered all the questions we had along the way.”

“We hired KCSI to replace the roof, siding, windows and doors on our 50 year old house. They have just finished and we were very pleased with the final product and the entire process. Mike handled the job from the estimation to the installation. The job was completed in a week and a half and Mike made sure all of our concerns were addressed while the work was being done. We could not give KCSI a higher recommendation.”
