About this company
K.O.S. Restoration is a family-owned restoration company based in Bellport, Long Island, serving Suffolk County, Nassau County, and Queens since 2006. Originally known as King of Steam, they handle water damage, mold remediation, mold encapsulation, fire damage, sewage cleanup, and asbestos removal. They also offer duct cleaning, carpet cleaning, and soft-washing, which generates a noticeable share of their review volume.
What stands out is their crawlspace and encapsulation work. They use Fiberlock IAQ 6100 spray-applied coatings and reference IICRC S520 mold remediation standards on their website. They coordinate asbestos testing through independent NY-licensed inspectors rather than doing it themselves, which aligns with New York State law requiring separation between testing and removal. For water damage, they advertise a 45-minute emergency response to Suffolk County and use Xactimate — the same estimating software insurance carriers use — to maximize claim payouts.
Tom, the owner, shows up frequently in reviews doing on-site inspections and estimates. Multiple reviewers mention him by name on mold jobs specifically. Brianna handles phone intake and gets praised for calming anxious callers. The company offers 0% financing through Wisetack.
324 Google reviews at a perfect 5.0 stars is rare for any restoration company, particularly one with this volume. The review base spans mold remediation, water damage, duct cleaning, and carpet cleaning — it is not concentrated in a single service line.

Erick shows up as a project manager on water damage jobs, sizing up situations quickly. Joe and Brandon appear on cleaning and duct work jobs.

K.O.S. operates across multiple service lines — restoration, remediation, carpet cleaning, duct cleaning, soft-washing. This diversification means their 324-review volume is spread across different types of work. The restoration and mold jobs that are most relevant to this directory represent a subset of that total. The company appears to funnel cleaning customers into restoration awareness and vice versa, which creates a broad base of repeat clients.

Keep in mind
- K.O.S. does both mold testing and mold remediation. When the same company tests for and fixes a problem, there is a financial incentive to find more work. Ask for a separate independent test before committing to remediation.
- Their review base includes a significant number of carpet cleaning, duct cleaning, and soft-washing jobs. A perfect 5.0 rating across 324 reviews reflects all service lines, not just mold and water damage work.
- The 45-minute response time applies to Suffolk County. Nassau and Queens are in their service area but response times will be longer from their Bellport headquarters.
- Their website is heavy on marketing language and emotional copy. The actual case studies (Westhampton Beach, Quogue, Hamptons crawlspace) are more informative than the service pages.
- They offer 0% financing through Wisetack. Get the total cost in writing before signing a financing agreement.
