March Home Maintenance Checklist: Pacific Northwest

March in the Pacific Northwest (PNW) means unpredictable weather—rain, occasional snow in higher elevations, and the first signs of spring. Homeowners should focus on moisture control, storm preparation, and early landscaping maintenance. Here’s your essential checklist.

1. Inspect & Maintain the Roof

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

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

• DIY Tip: Check for missing or curled shingles, inspect flashing, and clear moss or algae growth.

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

2. Clean & Repair Gutters & Downspouts

• Why It Matters: Spring showers require clear drainage to prevent flooding and water damage.

• Risk If Ignored: Clogged gutters can lead to roof leaks and foundation erosion.

• DIY Tip: Remove debris, flush gutters with water, and ensure downspouts direct water away from the home.

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

3. Inspect & Seal Windows & Doors

• Why It Matters: Keeping cold drafts out and preparing for warmer weather improves efficiency.

• Risk If Ignored: Increased heating and cooling costs, condensation buildup, and mold growth.

• DIY Tip: Apply weather stripping, caulk gaps, and install energy-efficient curtains.

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

4. Check for Flood Risks & Improve Drainage

• Why It Matters: Spring rain can lead to basement flooding if drainage systems aren’t functioning properly.

• Risk If Ignored: Water damage, mold growth, and foundation issues.

• DIY Tip: Test sump pumps, extend downspouts, and inspect yard grading for proper drainage.

• Estimated Cost If Ignored: Flood cleanup ($3,000–$10,000).

5. Trim Trees & Remove Weak Branches

• Why It Matters: High winds and wet soil can cause trees to fall or branches to break.

• Risk If Ignored: Roof damage, blocked driveways, and power outages.

• DIY Tip: Trim overhanging branches and remove dead or leaning trees.

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

6. Pressure Wash Walkways, Patios & Siding

• Why It Matters: Moisture buildup leads to slippery surfaces covered in moss and algae.

• Risk If Ignored: Increased risk of slips, falls, and long-term material deterioration.

• DIY Tip: Use a pressure washer on sidewalks, decks, and siding to remove buildup.

• Estimated Cost If Ignored: Driveway resurfacing ($1,000–$5,000).

7. Prepare Landscaping for Spring Growth

• Why It Matters: The mild climate means early plant growth, requiring timely lawn care.

• Risk If Ignored: Overgrown plants, weak lawn growth, and pest infestations.

• DIY Tip: Prune trees and shrubs, aerate the lawn, and apply fresh mulch to retain moisture.

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

8. Check & Service Lawn Equipment

• Why It Matters: Mowers and trimmers should be in working order before grass growth peaks.

• Risk If Ignored: Delayed lawn maintenance and costly equipment repairs.

• DIY Tip: Sharpen mower blades, change the oil, and check hoses and belts for wear.

• Estimated Cost If Ignored: Lawn equipment replacement ($300–$1,500).

9. Test Smoke & Carbon Monoxide Detectors

• Why It Matters: The transition into spring means increased use of gas appliances and ventilation changes.

• 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+).

10. Inspect & Secure Outdoor Furniture

• Why It Matters: Windstorms and spring rains can damage outdoor furnishings.

• Risk If Ignored: Broken furniture, displaced items, and unnecessary replacement costs.

• DIY Tip: Tie down furniture, store lightweight items indoors, and clean or reseal outdoor cushions.

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