Maintenance Planning

The Bay Area's mild climate is a blessing for homeowners — but it can also create a false sense of security. Without the harsh winters that force maintenance in other regions, it's easy to let property care slide until small issues become expensive emergencies.

This calendar ensures that never happens.

Spring (March - May): Renewal Season

Landscaping

✓Soil preparation and amendment for spring planting

✓Weed control — apply pre-emergent before weeds establish

✓Irrigation check — repair sprinklers, adjust timers for longer days

✓Mulch refresh — 2-3 inches of fresh mulch in all beds

✓Tree inspection — identify winter storm damage, schedule pruning

Property

✓Gutter cleaning — clear debris from winter rains

✓Pressure washing — clean driveway, walkways, and patio

✓Exterior inspection — check for cracks, peeling paint, damaged siding

Summer (June - August): Protection Season

Landscaping

✓Deep watering schedule — less frequent, deeper irrigation

✓Lawn care — mow higher (3-4 inches) to retain moisture

✓Hedge trimming — shape hedges and shrubs after spring growth

✓Dead heading — remove spent flowers to encourage new blooms

Property

✓Tree canopy thinning — reduce fire risk and improve airflow

✓Exterior maintenance — touch up paint, seal cracks before fall

✓Outdoor living prep — clean and repair patio furniture, pergolas

Fall (September - November): Preparation Season

Landscaping

✓Fall planting — ideal time for California native plants

✓Leaf removal — keep beds and lawns clear of fallen leaves

✓Aeration — loosen compacted soil for winter rain absorption

✓Fertilization — final feeding before dormancy

✓Weed removal — clear established weeds before they seed

Property

✓Gutter cleaning (critical) — prepare for rainy season

✓Roof inspection — check for damaged tiles, flashing, or seals

✓Storm preparation — trim overhanging branches, secure loose items

✓Exterior sealing — waterproof decks, fences, and wood features

Winter (December - February): Monitoring Season

Landscaping

✓Dormant pruning — ideal time for major tree and shrub pruning

✓Storm damage response — remove fallen branches promptly

✓Drainage check — ensure water flows away from foundation

Property

✓Mid-season gutter check — clear accumulated debris after storms

✓Foundation inspection — look for water intrusion or settling

✓Plan spring projects — get quotes and schedule early for best availability

The Cost of Skipping Maintenance

Preventive Service	Annual Cost	Emergency Alternative	Emergency Cost
Gutter cleaning (2x/year)	$400	Water damage repair	$5,000-$15,000
Tree pruning	$500	Emergency tree removal	$2,000-$8,000
Pressure washing	$300	Surface replacement	$3,000-$10,000
Weed control (quarterly)	$500	Full landscape restoration	$5,000-$15,000
Total preventive	$1,700	Total emergency	$15,000-$48,000
