Residential Pressure Washing in Alton, NH

At Splash, we clean just about every exterior surface on your property — house siding, patios, walkways, decks, fences, garage floors, pool Deck, retaining walls, and even outdoor furniture. We adjust water pressure and cleaning solutions based on the material (concrete, wood, vinyl, brick, stone, composite) to ensure a safe, thorough clean without damage

Pricing varies by job size, surface type, and level of buildup. We offer free quotes — just reach out with photos or your address and we'll give you an accurate, upfront estimate with no hidden fees.

Yes — when done by trained professionals. We use the right PSI (pounds per square inch) and nozzle tips for each surface. High-pressure is safe for concrete and stone; delicate surfaces like siding and wood get soft washing or lower pressure. We also protect plants, seal windows, and avoid electrical fixtures. DIY pressure washing causes most damage — our crew is insured and experienced in preventing issues like etching, splintering, or paint removal.How long does a typical residential pressure washing job take?

Most single services take 1–3 hours. A standard driveway is usually 45 minutes to 1.5 hours; a full house wash takes 2–3 hours; decks and fences range from 1–2 hours depending on size and staining level. If you're bundling multiple services (house + driveway + deck), plan for a half-day visit. We're efficient and respectful of your time — you don't need to be home, and we'll notify you when we're finished.

We use professional-grade, biodegradable detergents designed for exterior cleaning — they're tough on dirt, algae, and mold but safe for your landscaping and pets when applied correctly. Before we start, we pre-wet plants and cover sensitive greenery. After washing, we rinse thoroughly to dilute any residue. Your lawn, garden, and furry friends are safe. We never use harsh acids or bleach-heavy mixes that can burn vegetation.

Late spring through early fall (May–October) is ideal. Warmer temperatures help cleaning solutions work more effectively and surfaces dry faster. Many Alton homeowners schedule pressure washing in late spring to remove winter grime before summer entertaining, or in early fall to prep the home before winter. We operate year-round when temps are above freezing, but spring and fall offer the best results and weather conditions for outdoor work.
