Your deck and patio are meant to be used, not avoided because they look weathered or dirty. We clean outdoor living surfaces with methods matched to the material, helping bring back a cleaner, cared-for appearance.
Decks and patios live outside year-round. Sun, rain, shade, falling leaves, pollen, moisture, and everyday use all leave their mark.
Wood can gray and collect organic growth. Composite surfaces develop grime and staining. Pavers and patio surfaces can accumulate moss, algae, dirt, and buildup across both the surface and joints.
The challenge is that these materials aren’t interchangeable. Wood, composite decking, concrete, stone, and pavers may all require different pressure levels, chemistry, and cleaning techniques.
We start with the material and condition first, then build the cleaning approach around the surface.
What we address
Weathered surfaces that have lost some of their fresh, cared-for appearance through regular exposure.
Green or dark buildup that commonly develops in shaded or moisture-prone areas and can leave walking surfaces slick when wet.
Organic growth that settles into textured surfaces, wood grain, and patio joints.
Everyday environmental buildup that dulls wood, composite, pavers, and other outdoor materials.
“Our deck looks like new. Keystone did a great job.”— Jaimee R.
Method
Wood, composite decking, pavers, and other outdoor surfaces don’t respond the same way to cleaning.
We evaluate the material and condition first, then select the appropriate chemistry, dwell time, pressure, and equipment for the job. More delicate surfaces may call for lower-pressure or soft-washing techniques, while durable hardscapes may support a different process.
The goal is to remove the buildup effectively while minimizing unnecessary wear to the surface.
We also take care around furniture, planters, landscaping, and the surrounding property as part of the cleaning process.
Paver re-sanding & sealing
For paver patios and other appropriate hardscapes, re-sanding and sealing can be added after cleaning. We evaluate the pavers and their condition first, then recommend whether those additional steps make sense for your project.
It can if too much pressure or the wrong technique is used. Wood requires a more controlled approach, which is why we evaluate the boards and condition before selecting the cleaning method.
Yes. Composite materials collect dirt, organic growth, and environmental film just like other outdoor surfaces. We tailor the method to the material, finish, and condition.
Yes. We clean paver patios and other appropriate hardscape surfaces. Re-sanding and sealing can also be added after cleaning when appropriate for the condition and project.
Cleaning is often an important preparation step before refinishing because the surface should be free of dirt, organic buildup, and loose contaminants. If you’re preparing for a specific coating or refinishing project, let us know so we can discuss the condition and timing.
