The Exterior Asset Protection Company

Clean, safe, well-maintained properties attract customers and protect your brand.  Moss, algae, grime, and clogged roofs cut lifespan by years. We reverse and prevent that.  The average slip-and-fall claim costs businesses $20,000–$45,000.
Our program dramatically lowers that risk.

Our Subscription plans replace random, unexpected expenses while saving you on your insurance premiums.

We work with Restaurants, Retailers, Assisted Living Communities, Clinics & other high traffic businesses.

Kleene Shield is Washington’s Only Exterior Safety Certification Program—a systematic, technology-backed way to protect your property, your residents, your patients, and your business.

Kleene Shield Customer Feedback

What Our Clients Say:

We thought pressure washing was just about keeping things clean—until a customer slipped on algae outside our building. After hiring Kleene Shield, they identified risks we didn’t even know we had. The Safety Certification, the documentation, the routine maintenance… it’s a game-changer. Our walkways are spotless, compliant, and we finally have peace of mind. Worth every penny.

Jason M.

Property Manager, Redmond

We hired Kleene Shield thinking it would just freshen up the patio. Instead, they found slippery algae on our steps, drainage issues we’d missed, and a few spots that were real fall hazards. Their Exterior Safety Certification gave us a clear plan, and the results are incredible. The house looks amazing and I feel confident having family walk the property.

Sarah L.

Homeowner, Woodinville

Maintaining safe walkways, trails, and public areas across the city is a nonstop challenge. Kleene Shield’s assessments identified high-risk zones we hadn’t flagged yet, and their Exterior Safety Certification gave us documented proof of compliance. Since bringing them on, we’ve seen fewer slip incidents, cleaner facilities, and far less staff time spent chasing recurring algae and moss problems. They deliver exactly what a city needs—reliability, safety, and accountability.
