Restore Your Patios and Walkways
Concrete and masonry are porous materials that tend to 'soak up' stains and accumulate ground-in dirt. Our high-grade power washing services reach deep into the surface to lift contaminants that a garden hose simply can't touch.
Areas We Clean:
- Residential driveways and aprons
- Poured concrete and paver patios
- Sidewalks and entry walkways
- Pool decks and masonry walls
When concrete cleaning matters most
In Northern Virginia, the best window for concrete washing runs from late March through early November. Spring cleaning removes the grit, salt residue, and organic buildup that winter leaves behind, while fall cleaning keeps surfaces safe before leaves, moisture, and freezing temperatures arrive.
Concrete washing is especially valuable before a new outdoor living project. If you are planning a deck build, patio extension, or under-deck drainage installation, cleaning the surrounding hardscape first reveals hidden cracks, settled joints, and drainage problems that should be addressed during design. Homeowners preparing to list a property also benefit because a freshly cleaned driveway, walkway, and patio area can measurably improve curb appeal during showings.
Our concrete cleaning process
We begin every job with a walk-around assessment of the surface type, stain profiles, and surrounding materials that need protection. Oil and grease stains receive a degreasing pre-treatment that breaks the bond before any water touches the surface. For general algae, mildew, and ground-in dirt we use a soft-wash detergent application followed by controlled pressure rinsing.
Nozzle selection, pressure setting, and standoff distance are adjusted for the specific concrete — broom-finished driveways handle higher pressure than stamped or decorative surfaces. We rinse in overlapping passes working toward a drainage path so dirty water does not pool on already-cleaned areas. Adjacent landscaping, siding, and deck boards are pre-rinsed and protected throughout the process.
Surfaces we clean across Northern Virginia
Our concrete and masonry washing covers the full range of hardscape surfaces found around homes in Loudoun, Fairfax, Prince William, Arlington, and Stafford counties.
- Driveways and aprons: Removing oil drips, tire marks, rust stains, and winter salt residue from poured concrete and exposed-aggregate driveways.
- Walkways and entry paths: Eliminating algae, dirt film, and discoloration from front walks, side paths, and stepping-stone areas.
- Pool decks: Safely cleaning textured and cool-deck surfaces without altering slip-resistant finishes around the pool.
- Paver patios: Lifting dirt from paver joints and surface pores while preserving polymeric sand between the stones.
- Garage floors: Degreasing and cleaning concrete garage slabs that accumulate oil, coolant, and road grime over years of use.
- Retaining walls: Removing biological growth and mineral staining from block, stone, and poured retaining walls that frame outdoor living spaces.
Pricing and what affects cost
Most residential concrete washing projects in Northern Virginia fall between $200 and $1,000. The main cost drivers are total square footage, stain severity, surface type, and whether you add a protective sealer after cleaning. A standard two-car driveway with moderate algae staining typically lands in the lower portion of that range, while a large patio-plus-driveway project with oil pre-treatment and sealer application reaches the higher end.
We provide free on-site estimates so the price reflects your actual conditions rather than a generic quote. Request a concrete washing estimate and we will walk the surfaces with you before any work begins.

Local exterior cleaning context
Concrete Washing for Northern Virginia Outdoor Living Areas
This service is most useful for driveways, patios, walkways, pool surrounds and lower-level hardscape areas. Virginia clay, leaf tannins, algae, tire marks, rust and shade-driven biological growth can make concrete look older than the surrounding deck or patio.
Loudoun Decks treats exterior cleaning as part of the larger outdoor living system. A clean driveway, patio, fence or siding surface supports the way homeowners experience the deck, porch, railing and backyard as one space, not disconnected surfaces.
Cleaning process
- Inspect drainage, cracks, spalling, sealer condition and nearby landscaping before washing.
- Pre-treat oil, algae, moss, rust shadows and organic staining where appropriate.
- Use controlled pressure and surface-cleaning passes to avoid wand marks or unnecessary etching.
- Rinse away from foundations, low spots and newly planted beds whenever site conditions allow.
Concrete washing is often the right first step before sealing, patio upgrades, under-deck improvements or listing a home for sale. For larger backyard plans, pair this with deck construction, deck resurfacing, patio work, or a professional estimate request.
