Licensed #EASTGB744B1. Insured. Senior discounts available. Eastside Grab Bars is owned and operated by Mark Costello, and the business installs grab bars, applies non-slip floor treatments, upgrades home lighting, and conducts senior home safety assessments across all of East King County. The shop is in Issaquah on South East May Valley Road, which puts the service within a 30 minute drive of almost every home in the region. The service area stays focused on East King County on purpose. It allows fast response, low overhead, and real knowledge of the towns being served.
East King County is not one place. It is a long list of communities with very different housing stock, demographics, and safety needs. A rambler in Sammamish is a different install than a downtown Kirkland condo, which is a different install again from a retirement community in Newcastle or a foothill home in North Bend. All of them get the same careful, respectful approach.
The regular service area covers the Eastside cities and the neighborhoods and communities within them. That list includes:
Addresses outside that list are worth a call. Work happens in homes across East King County every week, and most visits happen within a few days of the first call.
East King County has one of the fastest-growing senior populations in Washington State. Many of the people who moved to Sammamish, Kirkland, and Issaquah during the tech booms of the 1990s and 2000s are now in their 70s and 80s. They live in homes built for a much younger version of themselves: split-levels with half-flights of stairs, tub-shower combos with high step-overs, sprawling single-story ramblers with long, dim hallways, and condos with shower thresholds that are hard on arthritic hips.
The region’s housing stock is also varied enough that no two installs look alike. The 1980s and 1990s construction common in Sammamish and Kirkland uses standard wood framing that accepts stud-mounted grab bars without issue. The newer homes in Snoqualmie Ridge and Issaquah Highlands often use metal framing in interior walls. Older homes in Mercer Island, Newcastle, and the established Kirkland neighborhoods sometimes have real plaster walls that call for a specific anchor approach. Waterfront condos along Lake Washington frequently have concrete or block walls behind the tile. Every one of those wall types calls for a different approach.
Staying local matters for this kind of work. A grab bar that feels solid on install day needs to still feel solid five years from now. If something ever loosens, shifts, or no longer fits how a person moves, the installer needs to be close by and reachable.
Mark founded Eastside Grab Bars after watching his own aging family members face the same hazards seen in client homes every week. After retiring from the US Small Business Administration in Seattle in 2021, he built this business around practical, local safety work for older adults.
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, where grab bars have gone into senior homes across King County, including many in communities now served as paid clients. That volunteer work has covered hundreds of homes and built a working knowledge of how every kind of East King County house is built.
Call Mark at (425) 522-8663, or send a message through the contact form for a same-day response. In-home safety assessments are available across Sammamish, Kirkland, Newcastle, Mercer Island, Snoqualmie, North Bend, and the rest of East King County. Senior discounts on labor are available on request.
