Diamond Power Washers is Reston's veteran and family-owned choice for exterior cleaning, and the reason is simple: we match the method to the surface. Reston is wood-sided contemporary clusters under one of Fairfax County's densest tree canopies, so the calls are about moss and algae, not road film. Most start with green streaking on a north wall or black growth on a shaded roof, and we clear it with a soft wash wood can take. Licensed and fully insured in Virginia, we serve Lake Anne, Hunters Woods, South Lakes, North Point, and every cluster between. Ask for a free, no-obligation quote.

Power washing in Reston, VA is not the same job as anywhere else in Northern Virginia. Reston was planned from scratch in 1964, and that design still shapes what grows on a home and how it has to be cleaned. Wood-sided contemporary clusters around Lake Anne, Hunters Woods, and Hickory Cluster sit under roughly half tree canopy, ringed by four lakes. The result is moss and algae on siding, roofs, decks, and docks, not road film.
That changes the method. Shaded, north-facing walls stay damp long after rain and grow green and black biological staining. High pressure scatters it and it returns. A soft wash kills it at the root.
Diamond Power Washers is veteran and family owned, licensed and fully insured in Virginia. We know what wood siding can take and what it cannot, and every job starts with a surface assessment and carries a 100% satisfaction guarantee. See our power washing FAQ for the common questions.
Ready to experience the difference that real expertise makes for your Reston property?
Two things drive cleaning in Reston: the canopy and the lakes.
Half of Reston sits under trees. For a cluster home near Hunters Woods, South Lakes, or North Point, whole sections of siding, roof, and deck spend the day in shade. Shaded surfaces hold moisture after rain and dew, and moss and algae need little more than that. On north and west walls the growth runs green on siding, black on rooflines, and slick on decks. House washing and fence washing both rely on soft wash, not brute pressure.
Then the lakes. Lake Anne, Lake Thoreau, Lake Audubon, and Lake Newport raise humidity on nearby lots. Lakefront decks, docks, and retaining walls collect algae and biological staining, and the wash has to account for runoff straight into the water.
Reston’s wood siding needs its own care. These are not 1990s vinyl colonials that shrug off aggressive pressure. Pressure that is routine on vinyl raises the grain and drives water behind the boards. A soft wash lifts growth without harming the wood.
Over all of it sits the Reston Deed, administered by the Reston Association through its Design Review Board, plus each cluster’s own association. Routine cleaning is one thing; restaining or altering a facade may need approval. We clean to whatever standard applies and will not create a problem with your association.
Local knowledge, matched to Reston’s canopy and lakes
Reston sits under roughly half tree canopy, and that shade drives most of the growth we clean. Humid summers feed moss and algae on siding, roofs, and decks that stay damp under the trees, worst on north walls that never dry after rain and dew. Four lakes push nearby humidity higher still. The dirt here is biological, not road grime, and knowing that lets us time a wash so results hold for seasons.
Built for Reston’s wood-sided homes
Reston’s housing is contemporary cluster architecture, much of it wood-sided, from Lake Anne and Hickory Cluster to Hunters Woods, South Lakes, and North Point. Wood, vinyl, and composite each call for a different pressure and solution. Aggressive pressure that is fine on vinyl raises the grain and drives water behind wood, so we default to a surface-matched soft wash.
Protecting Reston’s water
Reston drains toward the Potomac watershed, and its lakes make responsible runoff matter more, so we treat it seriously. We use biodegradable solutions and manage rinse water to keep detergents out of storm drains, streams, and the lakes. Effective cleaning and clean runoff are not a trade-off.
Every Reston job starts with the surface, not the schedule. On wood siding and shaded rooflines the default is soft wash: low pressure and a solution matched to the growth. Pressure alone clears what you see and leaves the biological material embedded, so it comes back fast. Soft wash kills the root.
Decks and docks near the lakes get assessed first. Treated wood, composite, and stone each take a different approach, and a weathered dock never gets driveway PSI. Our deck cleaning in Reston covers all of it, and the deck power washing guide walks through method and timing. Driveways and walkways get controlled pressure that lifts organic staining without etching. We match the method to the surface and keep runoff out of the lakes.

It depends on your home, so an honest quote starts with a look. Three factors move the price most: the size of the house, the surfaces involved, and how much moss and algae the canopy has grown. A compact cluster townhome with light growth costs less than a large lakefront contemporary with heavy north-side staining, a mossy roof, and a dock. Roofs, decks, docks, fences, and concrete each add scope. We do not quote a flat number sight unseen. Ask for a free, no-obligation quote and you will have a clear, itemized price before you commit.
About once a year for most Reston homes, and more often on the shaded sides. The canopy keeps north and west walls damp, so moss and algae return faster here than on open lots. Lakefront surfaces near Lake Anne, Lake Thoreau, Lake Audubon, or Lake Newport can need attention twice a year on the areas closest to the water. The simple test: check your north-facing siding and roofline after a wet spring. Growth back within a season means annual cleaning; growth faster than that means a twice-yearly pass on the worst surfaces. We can set a recurring schedule so you never track it.
Soft wash is the right method for Reston siding, especially the wood-sided contemporaries the community is known for. Soft wash uses low pressure and a cleaning solution that breaks down moss, algae, and mildew; the solution does the work, not force. High pressure on wood raises the grain, cracks aged caulk, and drives water behind the boards, and that damage costs far more than the wash saved. Pressure washing still belongs on the hard flatwork, so concrete driveways and walkways take controlled pressure matched to the slab. Soft wash for the house, controlled pressure for the concrete, never a high-pressure blast on wood.
For routine cleaning, generally no. Washing your siding, roof, or deck to clear moss and algae is upkeep and does not usually require sign-off. It changes if you alter the appearance: recoloring siding, restaining a deck a new tone, or any visible facade change can fall under the Design Review Board or your cluster association’s standards under the Reston Deed. When you are unsure, check with your cluster association or the Reston Association before restaining or repainting. We clean to whatever standard applies and work within your association’s process, so the wash never becomes a covenant issue.
Because shade and moisture never let them dry. Under Reston’s canopy, north-facing walls and roof slopes sit wet long after rain and dew, and that is exactly what moss and algae need to take hold. The four lakes add humidity for homes nearby. A neighbor on an open, south-facing lot can go years clean while your shaded north slope grows moss every season. It is geography, not a bad wash. Our roof cleaning in Reston uses soft wash because that black streaking roots into the shingle, and an annual cycle keeps it from coming back deep.
Yes, and soft wash is the only method we use on wood siding here. Reston’s contemporary clusters were built with wood-sided facades, and wood is far less forgiving than vinyl. High pressure raises the grain, splinters weathered boards, forces water behind the siding, and strips stain, and any of that can turn a cleaning into a repair. Soft wash uses low pressure and a solution calibrated to the moss and algae on your specific wall, lifting the growth without touching the wood underneath. We check the siding and any failing stain before we start, then clean to a genuinely restored surface that is not worse off for the wash.
