Spring Exterior Cleaning Checklist for NJ Homeowners: What to Do in What Order

Save and bookmark this: This is the actual order we recommend for spring exterior cleaning — built from five-plus years of doing this work across NJ homes. The sequence matters as much as the tasks themselves.

Every spring, we get calls from homeowners who did their cleaning in the wrong order — pressure washed the driveway before cleaning the gutters (which then dumped debris back on the driveway), or cleaned the windows before the house wash (which re-dirtied the glass). A little planning saves a lot of re-work.

Here's the checklist we give our own customers, with the reasoning behind the sequence.

Why Order Matters

Exterior cleaning follows gravity and flow. Debris, water, and cleaning solution move downward. Any work you do lower on the house will be re-contaminated if you haven't cleaned what's above it first.

The rule: always work top-down and inside-out. Roof before gutters, gutters before siding, siding before windows, windows before patios, patios before driveway.

The Rinse Prince sequence:

Roof → Gutters (flush) → House Wash (siding, trim, soffit) → Windows → Deck / Patio → Driveway & Walkways → Fence → Outdoor Furniture

The Full Spring Checklist

Step 1: Roof Inspection and Soft Wash

• Inspect for winter damage Do First
  Walk the perimeter and look up. Note any lifted, cracked, or missing shingles from ice and wind. Document before cleaning.
• Soft wash if algae streaking is present
  Black streaking means active algae. Soft washing kills and removes it without damaging shingles. Do not pressure wash roofing.
• Check flashing and ridge cap
  Winter expansion and contraction can loosen flashing. Flag anything that looks lifted or separated for a roofer.

Step 2: Gutters

• Clear all debris from gutters and downspouts Priority
  Fall and winter debris compacts in gutters over winter. Clear before any lower surface cleaning — flushing gutters will push debris down the exterior.
• Flush downspouts to confirm drainage
  Check that downspouts are flowing freely and directing water away from the foundation.
• Clean gutter faces (tiger striping)
  The vertical face of gutters develops dark streaking from electrostatic bonding. A gutter brightener treatment removes it.

Step 3: House Wash (Siding, Soffit, Trim)

• Soft wash all siding surfaces Core Service
  Removes algae, mold, mildew, pollen, and oxidation from vinyl, Hardie, stucco, brick, and wood siding. Do not high-pressure wash siding directly.
• Pay attention to north-facing walls
  North-facing surfaces get less sun and dry more slowly — they accumulate the most biological growth. May need extra treatment time.
• Clean soffits and fascia
  Often overlooked. Soffits collect cobwebs, wasp nests, and oxidation. Fascia gets splashed with debris from overflowing gutters.

Step 4: Windows

• Clean exterior and interior glass After Siding
  Always after the house wash — the siding rinse will splash back onto any glass you've already cleaned.
• Remove and clean screens
  Screens trap pollen and mold. Clean separately and let dry before reinstalling.
• Wipe sills and tracks
  Winter condensation leaves mineral deposits on sills. Track cleaning prevents future operational issues with sliding windows.

Step 5: Deck and Patio

• Inspect wood for winter damage before cleaning
  Look for split boards, soft spots (press with your foot), and lifting fasteners. Flag structural concerns before applying water.
• Pressure wash or soft wash based on material
  Wood decks: lower pressure, appropriate cleaner for wood. Composite decking: follow manufacturer guidance. Concrete patios: hot water rotary cleaning.
• Consider sealing wood decks after cleaning Recommended
  A clean, dry deck is the ideal time to apply sealant. Extends life significantly and reduces how much cleaning is needed next year.

Step 6: Driveway and Walkways

• Pre-treat stains before surface cleaning
  Oil, rust, and organic stains require specific pre-treatment agents. Applied 10–20 minutes before pressure washing for best results.
• Surface clean with rotary head (not wand)
  Rotary cleaning gives even, consistent results without the stripe pattern that wand cleaning leaves.
• Seal if last sealed more than 2 years ago Optional but Recommended
  Penetrating sealer protects against the next season's staining and dramatically reduces freeze-thaw damage in NJ winters.

Step 7: Fence and Outdoor Furniture

• Pressure wash fence (method varies by material)
  Vinyl fencing: moderate pressure, soft wash solution. Wood: low pressure + wood cleaner. Chain link: moderate pressure, rust treatment if needed.
• Unwrap and inspect outdoor furniture
  If furniture was shrink-wrapped over winter, inspect for any moisture intrusion or damage before the season begins.
• Clean furniture before seasonal use
  Patio furniture that sat uncovered through winter will have pollen, mold, and oxidation. A quick professional clean before your first outdoor gathering makes a noticeable difference.
