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!
KOS is a great service. I have used them 3 years in a row, and the team and service have never disappointed me. The service is thorough, courteous and accommodating.

Tom and his crew did an incredible job at our home. He was the only one to discover mold in our HVAC system after going through our basement. Our mold situation was taken care of then some. Very thorough and truly treated our home as if it was his own.

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.

I had a sudden leak from the upstairs shower that traveled down to my garage. Erick showed up within the hour! After looking over the damage we went over everything in detail that he found as well as what the process for remediation would look like to prevent further moisture and mold. The KOS crew arrived the day of and immediately started working. The office was wonderful in helping with speaking to insurance and helping get payment from them. Couldn’t recommend them highly enough! Thank you KOS RESTORATION!

KOS Cleaning and Restoration came out and did a bid on water damage in my crawl space from a broken water sewer line. Tom came within the hour gave us the most fair bid. The team arrived shortly after to start working. We went with them as they explained in detail the work scope and approximate completion date. Work was done in a professional manner. This included removal of water and muck out. Install fans and humidifier until dry. Installed new vapor barrier. I'm a retired homeowner with 2 properties I know good work when I see it. Workers were knowledgeable and polite. l'd highly recommend this company.
KOS did an amazing job with the mold remediation at my client's home for a very reasonable price.

FAQ'S About Siding Washing
What are those green and black streaks on my siding?
They’re usually algae or mold — both common in Long Island’s climate. They grow in damp, shady areas and can make siding look older than it is.
Is it safe to clean siding with pressure washing?
Traditional pressure washing can be too harsh. We use a soft wash method that’s safe and effective — no damage, just results.
Can you clean cedar or wood siding too?
Yes! We clean all types of siding, including cedar shake, vinyl, and more — safely and thoroughly.
Will this help increase curb appeal?
Absolutely. Clean siding makes a huge difference in how your home looks — and how people feel when they see it (including you!).
How long does it take?
Most homes are cleaned in just a few hours. We’ll schedule a time that works best for you, and you’ll see instant results.
