How Often Should You Clean Your Deck & Pool Deck in Alton?

For most decks and pool decks in Alton, NH, we recommend a professional cleaning at least twice per year — once in late spring (April or May) and again in early fall (September or October). Spring cleaning removes the winter buildup of dirt, pollen, tree sap, and mildew that accumulates during New Hampshire's wet season.

Pool decks especially benefit from mid-summer cleaning since they see heavy foot traffic, sunscreen oils, and constant splashing that create slippery algae and mold growth.

Even if you're on a twice-yearly schedule, pay attention to warning signs that your deck needs immediate attention. Green or black patches, a slippery film (especially after rain), visible mold or mildew in shaded areas, or discoloration around pool edges all indicate it's time for a cleaning. Homes surrounded by trees or located near the lake may need cleaning three or even four times per year due to constant shade, moisture, and organic debris. When in doubt, a quick professional soft wash can prevent small problems from becoming expensive repairs.

Benefits of our Alton Deck & Pool Deck Cleaning Services

At Splash Pressure Washing, we treat your home like our own. Discover how our professional exterior cleaning services preserve your property's integrity and aesthetic brilliance.

01.Prevents Slip Hazards & Improves Safety

Algae, mold, and mildew create dangerously slippery surfaces on wood and composite decks — especially around pools where water splashes constantly. Professional cleaning removes these organic growths at the root, restoring traction and making your deck safe for kids, elderly family members, and guests.

02.Extends the Life of Your Deck & Protects Your Investment

Dirt, pollen, and organic debris trap moisture against your deck boards, accelerating rot, warping, and splintering. Left untreated, mold eats away at wood fibers and composite materials, leading to costly board replacement within just a few years. A thorough pressure wash or soft wash removes these contaminants before they cause permanent damage, helping your deck last 10-15 years longer.

03.Restores Curb Appeal & Increases Home Value

A grimy, stained deck makes your entire backyard look neglected — and it's one of the first things potential buyers notice. Professional deck cleaning instantly reveals the original color and grain of your wood or composite, transforming a dull, gray surface back into a vibrant outdoor living space. Whether you're hosting summer BBQs or listing your home for sale, a freshly cleaned deck dramatically improves first impressions and can add thousands to your property's perceived value.

04.Removes Harmful Contaminants That Damage Finishes

Tree sap, bird droppings, pollen, rust stains, and tannin bleed don't just look bad — they actively break down sealants, stains, and protective coatings on your deck. Over time, these contaminants etch into the surface and become nearly impossible to remove without aggressive sanding. Regular cleaning neutralizes acids, lifts embedded stains, and keeps your finish intact, so you won't have to strip and re-stain prematurely. For pool decks, chlorine and salt also degrade surfaces if not rinsed away regularly.

Deck Cleaning FAQ

Got Questions About
Deck & Pool Deck Cleaning?

Get the facts on professional deck washing, stain removal, and seasonal maintenance for wood and composite decks in Alton, NH and the Lakes Region.

  • Absolutely! We specialize in cleaning cedar, pine, pressure-treated lumber, Trex, TimberTech, Azek, and all major composite deck brands. Each material requires a slightly different approach — wood decks need careful pressure adjustments to avoid splintering or grain damage, while composite decks are cleaned with low pressure and specific solutions to remove embedded mold, mildew, and tannin stains without harming the surface. We adjust our method to match your deck's material perfectly.

  • Not when done by professionals. The biggest mistake homeowners and inexperienced contractors make is using too much pressure — that's what causes splintering, gouging, and "furring" on wood decks. We use controlled low-to-medium pressure tailored to your deck's age and condition, combined with deck-safe cleaners, to lift dirt and organic growth without damaging the surface. For older or weathered wood, we may use a soft wash approach instead.

  • We recommend an annual deck cleaning — ideally in late spring or early summer before peak outdoor season. New Hampshire's climate creates the perfect storm for mold, mildew, algae, and pollen buildup on outdoor surfaces, especially shaded decks near trees or pools. Annual cleaning prevents deep staining, extends the life of your deck finish or sealant, and keeps the surface slip-resistant and safe. If you're planning to stain or seal your deck, a professional clean beforehand is essential for proper adhesion.

  • Yes, we ask that you remove or relocate grills, furniture, planters, and any decorative items from the deck surface before we arrive. This ensures we can clean every inch of the deck and prevents your belongings from getting wet or damaged. If you have large or built-in items you can't easily move, just let us know ahead of time and we'll work around them as best we can. We'll also pre-wet any nearby plants and landscaping to protect them from cleaning solutions.

  • Yes — that's exactly what we're here for. Black spots and green fuzz are mold, mildew, and algae that thrive on damp, shaded decks. Pool deck stains from chlorine, calcium buildup, and tannin leaching are also very common. Our cleaning process targets and removes organic growth at the root, along with mineral deposits and chemical residue. For extremely stubborn stains (like rust or deep tannin bleed on wood), we may recommend a secondary treatment or light sanding, but most decks look dramatically better after a single professional clean.

  • Most residential decks in Alton vary depending on square footage, number of levels, condition, and whether railings and stairs are included. Pool decks around inground or above-ground pools are typically priced separately. We offer free quotes — we'll come take a look, measure, and give you a firm price with no hidden fees. If you're bundling deck cleaning with house washing, roof cleaning, or other services, we can usually save you money on the total job.
