Winter is over. Here's exactly what needs cleaning — and the order to do it in — to get your home ready for the season.
Long Island winters are brutal on your home's exterior. Between nor'easters, salt spray from the coast, freeze-thaw cycles cracking your concrete, and months of accumulated grime — by April, most homes look significantly worse than they did in October. The question isn't whether your home needs spring cleaning. The question is where to start.
This checklist is what we use internally at Best Power Wash LI when we evaluate a Long Island property for a full spring cleaning package. We're sharing it so you know exactly what to look for, what to prioritize, and what method to use on each surface. Whether you hire us or tackle some of this yourself, this is the definitive spring power washing guide for Long Island homeowners.
Timing matters. Spring — specifically late March through May — is the ideal window for exterior cleaning on Long Island for several reasons:
Here's everything you should inspect and clean, organized by priority. We recommend tackling these from top to bottom — literally — since cleaning higher surfaces first means dirty water and runoff flows down to surfaces you haven't cleaned yet.
Start at the top. Long Island's coastal humidity creates ideal conditions for Gloeocapsa magma — the black algae that causes those dark streaks across your roof shingles. If you see black or dark green streaks, your roof needs professional roof cleaning.
Critical: Roof cleaning must ONLY be done with soft washing. High-pressure water strips the protective granules off asphalt shingles and can take 10-15 years off your roof's lifespan. The soft wash method uses low-pressure application (under 100 PSI) with a biodegradable cleaning solution that kills algae at the root level.
What to look for:
Your home's siding has been absorbing moisture, salt air, and organic growth all winter. Most Long Island homes have vinyl siding, which is durable but porous enough to harbor mold and mildew in its surface texture. House washing with a soft wash system is the safe, effective approach.
Walk around your entire home and look for:
If you have cedar shingle siding — common in older Long Island neighborhoods and waterfront areas — soft washing is even more critical. Cedar is a soft wood that high pressure will damage immediately, causing splintering and premature graying.
Gutters serve double duty on this checklist. First, they need to be cleared of debris so water flows properly (prevents fascia rot and foundation damage). Second, the exterior of your gutters accumulates those distinctive black "tiger stripes" — oxidation marks caused by a chemical reaction between the aluminum and pollutants running off your roof.
Soft washing handles both the exterior cleaning and removes the organic growth that clogs gutters from the outside. Interior gutter cleaning is a separate service — but both should be done in spring.
This is where pressure washing shines. Concrete driveways and sidewalks are tough enough to handle high-pressure cleaning, and after a Long Island winter, they usually need it. Salt damage, oil stains from snow blowers and cars, tire marks, and embedded dirt all need mechanical force to remove effectively.
Concrete washing typically uses 3,000-4,000 PSI with a surface cleaner attachment for even results. Look for:
If you have a paver patio, walkway, or driveway, spring is the time to evaluate the condition of both the pavers and the joint sand. Winter freeze-thaw cycles are the #1 cause of joint sand erosion and paver shifting on Long Island.
Our paver wash, sand, and seal service is most in-demand during spring because homeowners see the winter damage and want their outdoor living spaces ready for the season. What to check:
If the joint sand is compromised, cleaning alone isn't enough — you need a full wash, re-sand with polymeric sand, and professional sealing to lock everything in place and protect against future freeze-thaw damage.
Deck cleaning in spring is essential if you plan to use your outdoor space during summer. Wood decks absorb moisture all winter, and that trapped moisture feeds mold growth from the inside out. Composite decks fare better but still accumulate surface mold and staining.
For wood decks, a gentle cleaning followed by wood brightener prepares the surface for staining or sealing. For composite decks, soft washing removes organic growth without damaging the material. Fences get the same treatment — especially stockade fences that trap moisture between boards.
If you have a pool, your pool deck needs attention before opening season. Winter covers, standing water, and leaf debris leave concrete pool decks with significant algae and mold buildup — which isn't just ugly, it's a genuine slip hazard. Pressure washing the pool deck, coping stones, and surrounding hardscape should be done before you pull the cover off.
Window cleaning rounds out the spring checklist. Salt film from coastal air, pollen, and hard water spots all accumulate on glass through winter. Clean windows also let you spot seal damage and frame deterioration early.
Always clean from the top down. Here's the correct sequence for a full spring cleaning:
This sequence ensures that runoff from higher surfaces doesn't re-dirty lower surfaces you've already cleaned. It also allows the cleaning solution from the house wash to rinse down naturally.
Some items on this checklist are safe for homeowners to tackle. Rinsing off a patio with a garden hose, cleaning screens, or pulling debris from gutters are reasonable DIY tasks. But anything involving pressure washing or soft washing carries real risk if done incorrectly:
A complete spring exterior cleaning package varies by property size and condition, but here are typical ranges for Long Island homes:
Bundling services saves money. Most professional companies — including us — offer package pricing when you combine multiple services in a single visit, since the crew is already on-site with all equipment.
