I called KOS a couple of weeks before we were having an event at home. We have a cedar shingle home. They were contracted to soft-wash the house, wash the windows and concrete. They accommodated our schedule. Everything looks great. We plan to call them again next year.
I highly recommend this company. Family owned and very honest. Tom came out to the house and performed a thorough inspection for mold and water damage. I would definitely go with this company again.
Fantastic job, 2 guys, very attentive, took extra care of my shrubs, avoided a birds next next the roof.

I needed my store carpeting cleaned at my retail shop in SEtauket. I've been using them for years and wouldn't use anyone else. I used to do carpets in college and know how much work it is. KOS has a top notch steam machine, and they carry their own water so no hose hook up. It is super powerful for tough stains, leaves no residue and dries fast. Also the crews are always great. Today Joey and Brandon did a great job this review is long overdue so kudos to KOS!!

We contacted KOS after experienced a flood in our basement they immediately responded and had a crew out within an hour. Erick, the project manager was able to size up our situation immediately and had a crew to our house right away. They remediated and did everything to minimize cost while making sure our basement was completely dry and mold-free. I highly recommend KOS Restoration to come to your rescue. The entire team was professional and took great care in our situation. Thank you!
Brandon ,and Kamile did a terrific job on our AC system cleaning. They were professional, and addressed our concerns fully. We could not be happier with the outcome.

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!
As always KOS has done an excellent job cleaning our deck and side patio. Very professional. I would definitely recommend.
Team worked extremely well together and produced the best results throughout our home. All carpets looked new and refreshed. Highly recommended!
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.
