Washington Spring Home Maintenance Checklist

Washington Spring Home Maintenance Checklist

After months of rain, wind, and the occasional freeze, Washington homes emerge from winter needing attention. Spring is the ideal time to catch small problems before they become expensive repairs—and to prepare for the dry summer ahead.

The Washington Spring Timeline

  • March: Initial assessment as weather stabilizes
  • April: Major exterior work begins
  • May: Complete landscaping and prep for summer
  • June: Final checks before dry season

Post-Winter Damage Assessment

Winter takes a toll on WA homes. Here's what to inspect:

Roof & Gutters (Priority #1)

What to look for:

  • Missing, cracked, or curling shingles
  • Damaged flashing around chimneys, vents, skylights
  • Moss or algae growth (common in Western WA)
  • Sagging or detached gutters
  • Signs of ice dam damage (staining under eaves)

Gutter cleaning is critical. WA's heavy tree coverage means gutters clog constantly. Spring cleaning removes winter debris before the brief dry season—and before fall leaves make it worse.

Signs of gutter problems:

  • Water pooling at foundation
  • Streaks/staining on siding
  • Erosion in landscaping beds
  • Basement/crawl space moisture

Moss removal: That green carpet on your roof isn't just ugly—it holds moisture and degrades shingles faster. Options:

  • Zinc or copper strips along ridgeline (prevents regrowth)
  • Professional moss treatment ($200-$500)
  • DIY treatment with moss-killing products (follow label carefully)

Never pressure wash a roof. It damages shingles and voids warranties.


Foundation & Drainage

Inspect:

  • Foundation cracks (new or widened)
  • Soil settled away from foundation
  • Crawl space for standing water or moisture
  • Sump pump operation
  • French drain outlets—clear of debris?
  • Window well drainage

After a wet WA winter: The ground is saturated. Now is when you'll spot drainage problems that need addressing before next winter.

Red flags requiring professional assessment:

  • Horizontal foundation cracks
  • Cracks wider than 1/4 inch
  • Cracks that have grown since fall
  • Water intrusion in basement/crawl space

Siding & Exterior Walls

Check for:

  • Loose, warped, or damaged siding
  • Peeling or bubbling paint
  • Gaps in caulking around windows and doors
  • Signs of wood rot (probe with screwdriver)
  • Woodpecker damage (common in wooded areas)
  • Mold/mildew growth

WA-specific: Our wet winters accelerate wood rot. Catch it early—a small rot repair is $200-$500; replacing a whole section of siding is $1,000+.


Deck and Fence Inspection

Washington's moisture is brutal on outdoor wood.

Deck Checklist

  • Check for soft/spongy boards (rot)
  • Inspect ledger board connection to house (critical for safety)
  • Look for popped nails or screws
  • Test railings for stability
  • Examine stairs and support posts
  • Check under deck for moisture issues

Annual maintenance extends deck life dramatically:

  1. Clean with deck cleaner (not just pressure wash)
  2. Sand rough spots
  3. Apply water-repellent sealer or stain

Best time to seal/stain: Late spring when wood has dried from winter but before summer heat.

Fence Checklist

  • Check posts for rot at ground level
  • Look for leaning or loose sections
  • Inspect gates—hardware, hinges, latches
  • Examine boards for warping or splitting

Pro tip: The posts fail first in WA. If your fence is 10+ years old, probe the base of posts with a screwdriver. Soft = rot = post replacement needed.


HVAC Transition

Spring is when you switch from heating to cooling—and the perfect time for maintenance.

Heat Pump / AC Prep

  • Schedule AC tune-up (before summer rush)
  • Change air filter
  • Clear debris from outdoor unit (2-foot radius)
  • Check refrigerant lines for damage
  • Test cooling mode before you need it

Heat pump owners: Your system ran all winter in heating mode. Spring service catches wear before cooling season.

Close Out Heating Season

  • Final filter change
  • Note any issues that developed over winter
  • Consider duct cleaning if it's been 3-5 years

Landscaping Timing

WA's spring is ideal for many landscaping projects.

March-April

  • Prune trees and shrubs (before active growth)
  • Clean up winter debris
  • Prepare garden beds
  • Apply pre-emergent weed control
  • Aerate lawns (especially if compacted)

April-May

  • Plant trees and shrubs (native species establish well)
  • Divide perennials
  • Mulch beds (2-3 inches)
  • Overseed sparse lawn areas
  • Start irrigation system—check for leaks

May-June

  • Plant summer annuals
  • Final pruning on spring bloomers (after flowers fade)
  • Regular mowing schedule

Irrigation note: If you have an in-ground system, have it inspected and started professionally. WA freezes can crack lines and damage heads.


Windows and Doors

  • Clean windows inside and out
  • Inspect screens—repair or replace damaged ones
  • Check weatherstripping (replace if stiff/cracked)
  • Lubricate door hinges and locks
  • Test/lubricate sliding door tracks
  • Inspect window seals for fogging between panes

Spring Cleaning That Prevents Problems

Some cleaning tasks directly prevent future repairs:

Task Why It Matters
Clean dryer vents Fire prevention; efficiency
Service garage door Extends life; safety
Clean range hood filter Fire prevention; efficiency
Flush water heater Extends life; efficiency
Test smoke/CO detectors Safety compliance
Clean refrigerator coils Extends life; efficiency
