Homeowners in Millsboro see the same thing every spring. The deck looked fine in November, but a few months of Atlantic moisture and shade transform it into a patchwork of gray wood, algae slicks, and rust lines under the grill. You can ignore it and hope the first cookout distracts from the green tint, or you can restore it the right way with a professional deck wash that protects the wood, the fasteners, and your weekends. After years of watching the difference between quick, harsh pressure-wash jobs and careful, surfactant-driven cleaning, I’ve come to prefer crews that treat a deck like a system. Hose Bros Inc fits that profile, and they’ve made a habit of delivering consistent, durable results around Millsboro.
What a proper deck wash actually involves
A deck wash that lasts more than a couple of storms starts well before any water hits the boards. The first decision is chemistry, not pressure. Sun-baked pine and composite respond differently than ipe or cedar. A thoughtful technician looks for mill glaze, fungal staining, and extractive bleed. They note the age of the sealer and whether it was oil or water based. That evaluation determines whether the wash needs a sodium percarbonate cleaner that releases oxygen, a mild detergent blend for composites, or a selective use of sodium hypochlorite to address mildew.
Rinsing matters, but dwell time matters more. Most detergents need three to eight minutes to penetrate organic growth. An operator who rushes will compensate with more pressure and a tighter nozzle, the quickest way to furrow soft grain and leave zebra-stripe patterns when the deck dries. The best crews run fan tips, keep the wand moving, and use water as a carrier for the chemistry rather than the main event.
Fasteners and railings tell their own stories. If you see orange tear marks running down from screw heads, that’s ferrous bleed. A targeted acidic rinse will neutralize it without etching the surrounding wood. On vinyl railings, a non-abrasive surfactant and light agitation remove gray film without leaving a chalky residue. All of this adds minutes, but it buys you months of a clean, even surface.
Why Millsboro decks degrade the way they do
The climate pushes decks to accumulate growth faster than inland properties. Millsboro sits close enough to the coast to share the humidity, but with tree cover that often shades decks from midday sun. That combination encourages algae and lichen even on south-facing boards. Pollen settles in April, packs into gaps, then holds moisture against the joists. If the deck faces the Indian River Bay breeze, salt crystals can form a thin film that binds grime and accelerates oxidation on metal rail components.
I’ve seen brand-new pressure-treated pine develop green streaks in as little as eight weeks on lots tucked near wetlands off Route 24. Composite fares better against moisture staining, but it holds onto sunscreen, grill grease, and bird droppings, which turn into stubborn shadowing if you wait until fall. That context is why “deck wash near me” searches spike in late March and again in mid-June. The neighborhood effect is real. When one deck gets cleaned properly, most adjacent owners notice the before-and-after contrast and discover that their boards were not permanently gray. They were just dirty.
The trade-offs: pressure versus chemistry
Pressure washing feels satisfying. The strip of clean that follows the nozzle can hypnotize a DIYer into chasing perfection with ever-closer passes. The problem shows up two weeks later when the wood dries and the scan lines appear. You can sand out the stripes if you have time, but repeated milling of the wood shortens board life. Softwood like southern yellow pine takes damage fast, especially early spring when the fibers are still a bit swollen from winter moisture.
Chemistry, used responsibly, lets lower pressure achieve deeper cleaning. Sodium percarbonate lifts organics without bleaching tannins. It works well on decks that will be sealed with transparent or semi-transparent finishes. Sodium hypochlorite, at diluted concentrations with surfactants and controlled dwell, excels at neutralizing mildew and algae on both wood and composite. The key is protecting surrounding plants with pre-wet and post-rinse cycles, and neutralizing runoff. Good crews tarp when necessary, but experienced ones know that steady water flow and timing accomplish more than plastic sheeting in most cases.
Where Hose Bros Inc stands out
I prefer companies that treat a deck wash like a maintenance plan rather than a single event. Hose Bros Inc, based right here in Millsboro, works that way. They start with a walk-through and test spots. If you’ve got an older stain, they check whether it responds to a percarbonate lift or if a brighter will be necessary before resealing. On composite boards with capstock, they avoid abrasive pads that burnish the surface and instead lean on dwell-time chemistry and soft bristle agitation where needed around stair nosings.
A few hallmarks of a professional outfit show up repeatedly in their work. They control water lines so you don’t end up with a garden bed flood. They adjust pressure for rail balusters versus deck field boards. They rinse from the house outward so dirty water doesn’t flow back onto cleaned areas. These sound like small steps, yet they are the difference between a clean deck that dries evenly and one that shows swirl patterns and drip marks after the sun hits it.
Hose Bros Inc also understands the local building stock. Many Millsboro homes use fasteners with coated heads from early 2010s builds. Those coatings break down and stain under aggressive bleaching. Choosing a lower hypo concentration with targeted brightening prevents those orange comet tails that show up otherwise. On newer decks with hidden fasteners, they approach board edges carefully to avoid forcing water and grit into the gap clips.

Safety, plants, and the rest of your property
I’ve watched homeowners sanitize a deck and then spend two weeks nursing a rhododendron back to health. Plant protection is not optional. Pre-wetting foliage reduces uptake of any cleaner. Lightly misting during dwell time buffers the leaves and breaks down stray run-off. After the rinse, a quick final spray dilutes residual chemistry. Mulch can hold cleaner like a sponge, so a smart crew pulls it back from deck edges or uses catch mats on steep slopes.
Electrical safety counts too. Exterior outlets often sit on the house wall near deck stairs. GFCI covers help, but they are not designed for concentrated spray at close range. A basic painter’s tape wrap and careful wand angle prevent nuisance trips and potential hazards. Grill lines and quick-connects should be checked for leaks. Nothing ruins a wash day faster than a propane line that’s been nudged loose.
For multi-level decks, ladder placement and harness use can feel like overkill for a wash, but a professional who brings tie-offs for high railings is thinking clearly about risk, not just speed. Water makes everything slick. When someone respects that, they respect your property.

Timing and frequency around Delaware’s seasons
You don’t have to wash every month. You also don’t want to wait until algae has rooted deep in the grain. Most Millsboro decks do best with a proper wash once a year, sometimes every 18 months if the deck gets full sun and good airflow. If you like to reseal, the wash should happen a few days before, with a moisture meter reading below 15 percent before applying finish. Spring is popular for obvious reasons, but late summer washes set you up for a cleaner fall and less slippery leaves.
After a wash, a light maintenance rinse with a garden hose after big pollen dumps helps. If the grill gets heavy use, a quick degreaser wipe under the cook box keeps stains from migrating. Small habits extend the interval between professional visits.
Real issues a good deck wash solves
Beyond appearance, a solid deck wash addresses surface slipperiness, one of the most common safety complaints I hear. Green algae on north-facing steps turns into a slip-and-fall invitation after a rain. Even composite gets slick when biofilm accumulates. Thorough cleaning breaks that film and restores traction. Washes also reduce insect interest. Carpenter bees and ants prefer decaying fibers. When you remove the damp, dirty matrix, you remove some of the draw.
I’ve seen deck boards that looked destined for replacement respond beautifully after a proper wash and brightener. Grayed cedar took on a warm tone again, not fake-new, but honest and fresh. A homeowner had budgeted several thousand for board swaps, then redirected that money to a handrail upgrade because the structure proved sound once the grime lifted. That is not rare. Cleaning reveals the truth of the wood.
Common mistakes to avoid if you DIY
If you decide to handle your own deck wash, keep a few pitfalls in mind. Don’t start with a zero-degree nozzle, even if the algae looks stubborn. You’ll etch the wood, and those grooves trap future dirt. Don’t mix bleach and vinegar to make some homemade super-cleaner. That creates chlorine gas. Stick to compatible products. Avoid washing in direct midday sun when temperatures push past the mid-80s. Cleaners flash dry and leave blotches, and rinsing becomes a race you will lose. Finally, avoid over-wetting the space between boards. For decks over finished areas, excess water finds ceiling seams and can create stains below.
If any of that reads like a headache, that’s the point. A pro has already learned these lessons and priced the job to do it right the first time.
The value equation: what you actually pay for
Many “deck wash Millsboro” quotes look like a simple square-foot rate. That’s only part of the price. The valuable part is the decision-making around chemistry, the time spent on details like risers and railings, and the equipment that keeps PSI where it should be. Insurance matters too. Water and ladders create exposure. Ask for proof. You’re paying to reduce risk as much as to remove dirt.
A low quote that relies on raw pressure can cost you more when you’re sanding tiger stripes later. On the other side, a fair, transparent bid that explains process, products, and protection steps almost always predicts a better outcome. Hose Bros Inc typically walks customers through that, which shows in how many repeat clients they keep from one season to the next.
When a deck wash is not enough
Not every deck is a candidate for a simple wash. If the boards feel spongey at the fasteners or if you see black streaks that don’t budge with oxygenated cleaners, rot may be underway. Soft spots near post bases suggest trapped moisture and require more than surface care. If you smell a musty note after the deck dries, water may be sitting under boards or in a ledger connection. That is a structural concern, not a cosmetic one.
In those cases, a reputable company will tell you to pause the wash and inspect. It’s better to replace a few compromised boards than to shine up a surface that hides a problem. I appreciate when a cleaner is willing to earn less today to earn trust for tomorrow.
What to expect on the day of service
A well-run crew arrives with hoses long enough to avoid dragging machines across your lawn beds. They ask about water spigots and shut-off valves. They walk the deck with you, point to areas of heavy growth, and test a small patch to confirm cleaner choice. During the work, they stage the wash from the house outward, split the job into manageable sections, and control run-off. They communicate about any unexpected issues, like a loose baluster or nail pop. When they leave, the deck looks uniformly clean, but the best test is the next day after a full dry. Color should be even, grain unscored, and no chalky residue underfoot.
Small details that add up to better results
Corners and step noses trap grime and show wear first. Using a hand brush on these spots keeps the field boards from being overworked. Fastener heads get a targeted pass to remove halos without blowing out the surrounding lignin. Ledger boards under the door threshold deserve attention, since that’s where splashback accumulates. If your deck meets siding, careful wand angle avoids driving water up behind clapboards or vinyl laps. On composite, removing the black lip at the drip line along the board edge is often what makes the deck look fully renewed. That lip is a mix of UV oxidation and grime that needs both chemistry and patient rinsing.
Why local matters for deck wash services
A Millsboro crew like Hose Bros Inc spends every season on the same species of wood, the same composites, the same hardware, and the same microclimates. That repetition builds an intuition you can’t buy in a manual. They know which neighborhoods hold shade well past noon and which lots bear more salt. They know when pollen peaks and when the marsh gnats show up, which surprisingly affects dwell time since flies love a wet deck. Local knowledge translates to better sequencing, cleaner run-off control, and realistic expectations on dry time before a birthday party or a family visit.
Preparing your deck for a professional wash
You can make the work smoother by clearing furniture and planters a day ahead. If anything is too heavy, leave it and note it during the walk-through. Sweep loose debris so cleaners work on the actual surface, not on a layer of pine needles. If you have delicate herbs or annuals tucked near the edge, flag them so the crew can shield them or pre-wet more aggressively. Cover the grill if you prefer, though most professionals will wrap it or move it temporarily. Keep pets inside, and if you have an automatic sprinkler system, shut the schedule off for the day to prevent interference with dwell times.
What clean looks like two months later
The true measure of a deck wash shows up after a couple of storms and a week of humidity. A good job holds its tone without gray creep at the board ends. Steps stay grippy when wet. Railings don’t develop chalk lines or drip marks. If your deck is in deep shade, a light green haze may reappear on the outermost edges by mid-summer. That is normal in heavy-growth zones. A quick service visit or a homeowner rinse keeps it at bay. Most clients find that the first professional wash resets the deck enough that simple upkeep becomes realistic again.
The long view: pairing washing with sealing or staining
A wash prepares the surface. It does not seal it. If you like a clear, natural look, a penetrating water repellent with UV inhibitors helps hold color and reduce checking. Semi-transparent stains add tone and protect longer, though they require more discipline in future maintenance to avoid film build. The wash should always precede any coating by at least 48 hours in moderate humidity, longer if the deck sits low to the ground. Moisture content, not guesswork, should govern timing. A meter reading gives you confidence that a finish will bond.
Professionals who handle both washing and finishing can stage the work properly, adjust cleaner selection to avoid residue that interferes with stain adhesion, and spot-sand only where needed rather than sanding an entire deck because of under-rinsed detergent. That integrated approach reduces waste and rework.
A word about composites and PVC
These materials resist rot, but they show dirt differently. The capstock surface can hold onto oily stains that a general-purpose house wash won’t lift. On dark composite, aggressive cleaners can haze the surface if left too long. A measured blend, soft bristle agitation near traffic lanes, and careful rinse patterns bring back the factory sheen without streaks. PVC boards scratch easily, so the operator’s brush choice matters. On both materials, paying attention to drip edges and fascia facing sun exposure prevents the shadow lines that make a clean deck look uneven in afternoon light.
The bottom line for homeowners searching “deck wash near me”

It calls for judgment about chemistry, patience with dwell times, and respect for the building materials. Around Millsboro, Hose Bros Inc has built a reputation on that combination. They show up prepared, protect what surrounds the deck, and leave a surface that holds up through the season.
If you’re planning a party, hosting family from out of town, or just tired of the green tint on your steps, schedule earlier than you think you need. The calendar fills fast once neighbors see a good before-and-after.

Quick prep checklist before your appointment
- Move furniture, rugs, and planters off the deck; sweep loose debris. Identify delicate plants near edges and point them out for extra protection. Close windows and check exterior outlets; keep pets indoors. Confirm access to an outdoor spigot and clear a path for hoses. If sealing after, plan for at least two dry days post-wash.
