April Home Maintenance Checklist for the Pacific Northwest

April in the Pacific Northwest (PNW) brings consistent rain, fluctuating temperatures, and the start of spring growth. Homeowners should focus on moisture control, exterior maintenance, and preparing outdoor spaces for warmer weather. Here’s your essential checklist.

1. Inspect & Maintain the Roof

• Why It Matters: Winter storms may have caused damage, and spring rains will test the roof’s durability.

• Risk If Ignored: Leaks, insulation damage, and mold growth.

• DIY Tip: Check for missing or damaged shingles, inspect flashing around chimneys and vents, and remove moss buildup.

• Estimated Cost If Ignored: Roof replacement ($7,000–$15,000).

2. Clean & Repair Gutters & Downspouts

• Why It Matters: The PNW experiences heavy spring rains, making proper drainage essential.

• Risk If Ignored: Water overflow can cause foundation damage and basement flooding.

• DIY Tip: Remove leaves and debris, flush gutters with water, and check downspouts for proper flow.

• Estimated Cost If Ignored: Water damage restoration ($3,000–$7,000).

3. Inspect & Seal Windows & Doors

• Why It Matters: Reducing drafts helps with temperature control as spring weather shifts.

• Risk If Ignored: Higher energy costs, increased humidity, and potential mold growth.

• DIY Tip: Apply weather stripping, caulk around windows, and replace damaged screens.

• Estimated Cost If Ignored: Window replacement ($300–$1,200 per window).

4. Test & Prepare the Air Conditioning System

• Why It Matters: While summers in the PNW are mild, cooling systems should be checked before temperatures rise.

• Risk If Ignored: Reduced efficiency, unexpected breakdowns, and high energy bills.

• DIY Tip: Replace air filters, clean vents, and schedule an HVAC tune-up.

• Estimated Cost If Ignored: AC replacement ($4,000–$10,000).

5. Check for Basement & Crawl Space Moisture Issues

• Why It Matters: The wet climate can lead to mold and mildew buildup.

• Risk If Ignored: Structural damage, poor air quality, and increased pests.

• DIY Tip: Look for condensation, install a dehumidifier if needed, and check for leaks in the foundation.

• Estimated Cost If Ignored: Mold remediation ($1,500–$6,000).

6. Prepare Landscaping for Spring Growth

• Why It Matters: The mild climate allows for early plant growth, but it also encourages weeds and overgrowth.

• Risk If Ignored: Overgrown yards, nutrient depletion, and pest infestations.

• DIY Tip: Prune trees and shrubs, aerate the lawn, fertilize, and apply mulch.

• Estimated Cost If Ignored: Landscape repair ($1,500–$5,000).

7. Pressure Wash Walkways, Decks & Siding

• Why It Matters: PNW’s damp conditions encourage moss and algae growth on surfaces.

• Risk If Ignored: Slippery surfaces, material deterioration, and reduced curb appeal.

• DIY Tip: Use a pressure washer to clean decks, patios, and driveways to remove grime buildup.

• Estimated Cost If Ignored: Deck refinishing ($1,500–$5,000).

8. Test Smoke & Carbon Monoxide Detectors

• Why It Matters: Seasonal HVAC system changes require safety checks.

• Risk If Ignored: Fire hazards and carbon monoxide poisoning.

• DIY Tip: Replace batteries, test alarms, and install additional detectors if needed.

• Estimated Cost If Ignored: Fire damage restoration ($10,000+).

9. Inspect & Maintain Outdoor Furniture & Structures

• Why It Matters: The rainy season can take a toll on outdoor furnishings.

• Risk If Ignored: Rust, rot, and costly replacements.

• DIY Tip: Clean and seal wooden furniture, check for rust on metal frames, and store cushions in dry areas.

• Estimated Cost If Ignored: Outdoor furniture replacement ($500–$3,000).

10. Secure the Home for Spring Storms

• Why It Matters: High winds and heavy rain can damage unsecured items.

• Risk If Ignored: Broken windows, property damage, and water intrusion.

• DIY Tip: Tie down outdoor furniture, check sump pumps, and inspect weather seals on doors.

• Estimated Cost If Ignored: Storm damage repair ($3,000–$10,000).
