Poseidon Exterior Cleaning is a locally owned exterior cleaning company serving Greenville, South Carolina, and communities across the Upstate. Founded in 2022 by owner Mark Osborn, the business focuses on punctual, professional service and careful work that leaves properties cleaner while helping protect exterior surfaces. Its team adapts cleaning methods to the material, using high-pressure techniques for durable areas and low-pressure soft washing for more delicate surfaces.

Services include power washing and pressure washing for driveways, sidewalks, concrete, brick, and other sturdy surfaces; soft washing for siding and painted areas; and roof washing to remove algae, moss, and debris while protecting shingles. The company also provides window detailing to clear dirt and streaks from glass and frames, along with gutter cleaning to remove leaves and blockages and support proper drainage.

Poseidon serves Greenville, Taylors, Greer, Simpsonville, Mauldin, Spartanburg, Anderson, Easley, Clemson, and Travelers Rest. Customers can call or text to discuss a project and request a free quote.
