May 2026 Home Maintenance Guide

 As spring fully settles into the Pacific Northwest, May is one of the best months to prepare your home for the warmer, drier season ahead. In the Puget Sound region, the combination of lingering rain, blooming landscaping, and increasing temperatures makes this the perfect time to tackle preventive maintenance before summer arrives.

Whether you own a cozy bungalow in Seattle, a waterfront property near Tacoma, or a suburban home in Bellevue, these May home maintenance tips will help protect your investment, improve efficiency, and keep your property looking its best.

 
1. Inspect Your Roof & Gutters After Spring Rain
The Puget Sound area experiences heavy rainfall throughout the year, and May is the ideal time to inspect for winter and spring storm damage.

What to Check:
·         Missing or curled shingles
·         Moss or algae growth
·         Clogged gutters and downspouts
·         Water stains in attic spaces
·         Loose flashing around chimneys or vents

Pro Tip:
Moss thrives in the damp Pacific Northwest climate. Remove moss carefully and consider installing zinc or copper moss prevention strips to extend the life of your roof.


2. Pressure Wash Exterior Surfaces
Months of rain can leave dirt, algae, and mildew buildup on exterior surfaces.

Areas to Clean:
·         Siding
·         Driveways
·         Patios
·         Decks
·         Walkways
·         Fences

A thorough pressure wash instantly boosts curb appeal and helps prevent long-term surface damage.


3. Prepare Your Lawn & Landscaping
May is peak growing season in Washington State, making lawn care especially important this month.

Recommended Tasks:
·         Apply fertilizer
·         Add fresh mulch to flower beds
·         Prune shrubs and trees
·         Remove weeds before summer growth explodes
·         Check irrigation systems for leaks or inefficiencies

Native Landscaping Tip:
Consider drought-tolerant Pacific Northwest plants to reduce water usage during the dry summer months.

 
4. Service Your HVAC & Heat Pump Systems
Before summer temperatures rise, schedule a professional HVAC inspection.

Maintenance Checklist:
·      Replace air filters
·      Clean vents and returns
·      Inspect heat pump performance
·      Test thermostat settings
·      Clear debris around outdoor units

Many Puget Sound homeowners rely on heat pumps year-round, so preventive maintenance can improve efficiency and lower energy costs.

 
5. Check Windows & Doors for Drafts
Even in spring, Puget Sound weather can shift quickly.

Inspect For:
·      Cracked caulking
·      Damaged weather stripping
·      Condensation between window panes

Proper sealing helps improve comfort and energy efficiency throughout the year.

 
6. Clean & Seal Decks for Summer Entertaining
Decks take a beating during the wet Washington winters.

Important May Tasks:

Real Estate Insight:
Outdoor living spaces are highly desirable in the Puget Sound market. A well-maintained deck can significantly enhance your home’s appeal and value.

 

7. Test Outdoor Faucets & Sprinkler Systems
Freezing winter temperatures can occasionally damage outdoor plumbing.

Be Sure To:
·         Test hose bibs for leaks

Catching issues early can help avoid costly water damage later.

 
8. Inspect Your Foundation & Drainage

·      Cracks in concrete

Homes in the Pacific Northwest benefit greatly from proper water management due to the region’s wet climate.
