When we found ourselves with a big leak and mold situation and in a time-crunch to remediate it, Tom and his crew at K.O.S. came immediately, put me in touch with a company to test the mold, and then went above and beyond, working quickly and thoroughly to dry out our place and remediate the mold. The whole process went more painlessly and smoothly than we could have imagined -- I'm so grateful to them. I cannot recommend K.O.S. more highly!

I can’t say enough good things about KOS Cleaning and Restoration! From start to finish, they were professional, responsive, and incredibly thorough. The team arrived on time, explained every step of the process, and took great care to protect our home during the work. They were honest about what needed to be done (and what didn’t), which gave us so much peace of mind. The results were excellent—our space feels clean, safe, and fresh again. It’s clear they take pride in what they do and genuinely care about their customers. If you’re dealing with mold and want it done right the first time, I highly recommend KOS. A+ service all around!

We cannot recommend KOS highly enough. From the moment they arrived, it was clear we were working with professionals who truly care about their clients. Not only were they polite, thorough, and respectful of our home, but they were also the only company to detect additional mold damage that we were completely unaware of, damage that other companies overlooked entirely. Their findings prompted us to call our home inspector back to re-evaluate the situation. What truly stood out was their honesty and compassion. They explained everything in clear, understandable terms and never pressured us into unnecessary services. In an incredibly generous gesture, they loaned us an air purification machine free of charge while we coordinated additional work with another contractor. The team was fast, efficient, and left the space spotless. Every staff member we encountered was pleasant, knowledgeable, and professional. It’s rare to find a company that blends technical expertise with genuine kindness and integrity but KOS does just that. If you're dealing with mold or air quality issues, look no further. This is the team you can trust! Thank you.
