Why Gaithersburg Homeowners Choose Us
Gaithersburg is one of Montgomery County's largest and most diverse cities, featuring a wide range of residential communities — from planned communities like Kentlands and Lakelands to established neighborhoods like Diamond Farms and Washington Grove. Its suburban character, significant tree coverage, and frequent rain make regular exterior cleaning a priority for local homeowners.
Your deck takes more abuse than almost any other surface on your property — constant sun exposure, rain, foot traffic, and organic growth all work to break down wood fibers and grey the surface. Whether you're prepping for a new stain coat, hosting a summer gathering, or simply want your outdoor space looking its best, OneNation's professional deck cleaning service delivers a deep, thorough clean that protects your investment.

Prep for Stain & Sealant
A professionally cleaned deck provides the bare, open-grain surface that stains and sealants need to penetrate and bond properly. Skip this step and you're wasting money on product.
Safe on Wood & Composite
We calibrate pressure, temperature, and cleaning solution concentration specifically for your deck material — protecting the surface while removing all contamination.
Mold & Algae Elimination
Deck surfaces are prime habitat for mold, mildew, and algae. Our treatment kills these organisms and removes the discoloration they leave behind.
Slip Safety
Algae and mildew on deck boards create dangerous slip hazards. Our cleaning restores safe, non-slip texture to deck surfaces.
Our Deck Cleaning Process in Gaithersburg
Deck Inspection
We assess the deck material, existing finish condition, mold and mildew level, and determine appropriate pressure and chemistry for the job.
Furniture & Perimeter Protection
Deck furniture is moved and nearby landscaping is protected before we begin the cleaning process.
Deck Wash
Low-to-medium pressure washing with appropriate deck cleaning solution, working with the grain to clean boards thoroughly without raising grain or damaging composite material.
Rinse & Brightening
Final rinse removes all cleaning solution. For wood decks, we can apply a wood brightener to restore natural wood tones and open the grain for staining.
