Buying a new home is stressful enough but when we found mold in the kitchen it knocked that stress level. We were very lucky to have found KOS Restoration. Tom was open and upfront about the steps that had to completed and their potential costs. Tom was knowledgeable about the why, what and how for the process. The crew was professional through and through. Constantly kept us up to date of what was happening. They were more than tolerant of the numerous questions that was asked. I would highly recommend them to anyone looking for mold remediation work in the area and any families going through this stressful process. Thank you KOS Restoration!

Tom from KOS Restoration was very helpful and kind. I was so scared we had a mold problem in our house after discovering some blackened wood behind our drywall. They picked up the phone promptly and got someone out to look at our issue the same day. The team showed care and concern that we had small children in the house and wanted to solve our problem asap. Extremely impressed and pleased with this company. They went above and beyond what was expected to inspect and remediate mold. Helped us with other issues that we had questions with around our house. Knowledgable, prompt, and kind to work with

KOS Cleaning and Restoration is everything you could ask for and a family owned business!!! We had some mold issues pop up in our attic on an inspection report during the sale of our home. We had 3 different companies come out to provide an evaluation for us. We went with KOS and the quote was free, they were right on time and super communicative! Tom personally called me throughout the process and kept me updated every step of the way. They truly make you feel like the most important person to them and as someone who deals with contractors every day, my husband and I can honestly say we were so impressed by their professionalism, attention to detail and quality of work. Thank you again to this amazing company!!

KOS Cleaning and Restoration is the VERY BEST. I contacted other companies however Tom from KOS provided the best assessment, of the situation and had a concrete plan to prevent the chances of the mold returning in my basement. The company made special effort to make sure that our family was comfortable as we moved through the process and that included the field team as well as the office girls. This included text, phone calls and pictures. I can’t say enough about the knowledge, professional, attention to detail and customer service of KOS Cleaning and Restoration!

I had an ongoing roof leak that I was not aware of until it resulted in mold growth on the inside of the attic space. KOS Restoration promptly responded to my call. Their estimator came out as scheduled, was very knowledgeable and gave a reasonable estimate. The restoration team arrived as scheduled and completed the work as anticipated. Everyone was very polite and efficient. I would highly recommend this company.

The KOS team really went above and beyond remediating my home after I had a pipe burst. They used protective plastic to cover all my belongings to make sure nothing else was further damaged. They were willing to answer all my questions, and I had a lot! They talked me through everything they were doing and made sure the work was up to par with my standards. They were able to extract at least 3 inches of standing water and even ripped up the damaged flooring the water caused all before the day was done. I told my friends and neighbors about this company and told them to call KOS if they have any problems, I highly recommend KOS. Such a great company!!!

So the morning after Thanksgiving, we woke to a completely flooded finished basement. Water POURING out of the water heater. Called K.O.S Restoration on a referral. Tommy and his team were at my home in 1 hr....5 men carefully and efficiently moving ALL the contents of 40 years up to my living and dining room while sucking up the water with the equipment, tons of professional fans, dehumidifers. They had to remove the paneling and sheetrock, ceiling tiles...my basement is down to the studs. This was completed by Saturday afternoon. It was a shocking and stressful situation and Tommy made us SO comforted and at much as ease as possible knowing the job would be handled correctly. He provided an insurance adjuster to work with and "held our hand" for the next 5 days enduring all was DRY, cleaned, and tested all areas fortunately free of mold. We have a long road of repairs ahead of us...but are so grateful for team KOS to get us to where we can do that. I pray you will not need this type of service, but if you do...there is NO ONE I would recommend higher that KOS. Five stars isn't enough!! Tommy, thank you thank you thank you with so much gratitude, Gayle and Gregg Ross
