Licensed #EASTGB744B1. Insured. Senior discounts available. Eastside Grab Bars is owned and operated by Mark Costello, and the business applies professional non slip floor treatment for homeowners across East King County who want safer footing in showers, tubs, tile bathrooms, kitchens, and entryways. The treatment is invisible, lasting, and one of the most affordable safety upgrades an older adult can make.
A wet tile floor is one of the leading hazards in any home with a senior. Grab bars help at the wall. Shower seats help at the stall. But the floor itself is where most slips start. Non slip floor treatment changes the surface of the tile, stone, or tub so a wet foot grips instead of slides. Residents of Issaquah, Bellevue, Redmond, Sammamish, Kirkland, Newcastle, and anywhere in East King County can usually be scheduled within a week.
Bath mats slide. Rubber decals peel. Adhesive strips yellow, curl, and trap mildew. None of those products change the actual danger, which is the floor itself. A proper non slip floor treatment is a chemical process that opens microscopic pores in the surface of ceramic, porcelain, stone, concrete, or porcelain-enameled tubs. Water fills those pores and creates suction under the foot. The floor looks the same. It feels the same when dry. It grips a wet foot like a rubber mat would, without any visible product on the surface.
The National Floor Safety Institute tests slip resistance using a coefficient of friction measurement. A typical wet tile floor measures well below the 0.42 wet coefficient recommended for walking surfaces. After treatment, most tile and stone surfaces measure at or above that threshold, often well above. That is the difference between a floor that slides and a floor that holds.
Non slip treatment is not a fit for every surface. It does not work on fiberglass or acrylic tubs and shower pans because those surfaces are not porous. It also does not work on most vinyl, laminate, or finished hardwood. For those floors, other options make more sense: textured adhesive strips, replacement surfaces, or covered runners. Honest guidance at the visit sorts out which approach fits each floor.
A non slip floor treatment visit is usually a few hours from start to finish.
A call or email starts with a description of the floor. Tile, stone, tub surface, square footage, and current slip concerns. Ten minutes on the phone is enough to plan for the visit.
On arrival, a small area of the surface gets tested first. Different tile and stone surfaces react differently to the treatment. The test points to the right chemistry and dwell time for each specific floor before the whole area gets treated.
Surrounding walls get masked off, the surface gets wet, the treatment gets applied, and it works for the correct time. The surface then gets scrubbed, rinsed with plenty of water, and neutralized. Most bathrooms are done in one to two hours. Larger floors take longer.
Before leaving, Mark runs a wet-foot test with the homeowner present so the difference is felt right away. The floor is safe to walk on immediately after the final rinse. Clear guidance on ongoing cleaning and what to avoid keeps the treatment lasting.
Mark founded Eastside Grab Bars after watching his own aging family members worry about slipping in the shower. Grab bars solved part of the problem. A safer floor solved the rest. Non slip floor treatment joined the service list once it became clear how many clients needed both. After retiring from the US Small Business Administration in Seattle in 2021, he built the business around the full set of upgrades that keep older adults safe at home.
Mark holds the Aging in Place Home Safety Advisor designation through Age Safe America, the largest aging-in-place advocacy organization in the country. He also volunteers with Rebuilding Together Seattle, installing safety upgrades across King County for low-income seniors. Non slip treatment is one of the most requested items in that volunteer work because it is affordable and it lasts.
Most treatments hold their grip for three to five years with normal household cleaning. Harsh acidic cleaners, bleach, or abrasive pads can wear the treatment down faster. Safe cleaning product guidance goes to every client before the job ends so the result lasts.
No. The chemistry works below the visible surface. A polished tile still looks polished. A matte stone still looks matte. The only thing that changes is how the surface feels under a wet foot.
Yes. Once the surface is rinsed and neutralized at the end of the application, the floor is safe for immediate use by adults, children, and pets. The final surface is chemically stable and food-safe on kitchen floors.
