Get your home ready for the changing seasons with these essential September tasks!

πŸ‚ LAWN & LANDSCAPE

🌱 Lawn Revival Time

  • Overseed your lawn - September is prime time for cool-season grass seeding in NY

  • Apply fall fertilizer - Give your grass the nutrients it needs before winter

  • Keep watering - Don't let that late summer heat fool you, your lawn still needs hydration

πŸƒ Leaf Strategy

  • Start raking early fallen leaves - Don't let them smother your grass

  • Mulch flower beds - Use those leaves! Free mulch for winter protection

  • Plant fall mums and asters - Add some seasonal color before the real cold hits

🏠 EXTERIOR MAINTENANCE

🧹 Gutter Game Strong

  • Clean gutters and downspouts - Before the leaf avalanche begins

  • Check for loose or damaged gutters - Those summer storms can be rough

  • Install gutter guards if you don't have them - Future you will thank you

πŸ” Home Exterior Inspection

  • Walk around your home - Look for cracks, gaps, or damage from summer heat

  • Check caulking around windows and doors - Seal up before heating season

  • Inspect roof and siding - Better to catch problems before winter weather hits

πŸͺŸ Window Wisdom

  • Clean windows inside and out - Maximize that beautiful fall light

  • Check window screens - Repair or replace damaged ones

  • Test storm windows - Make sure they're ready for action

πŸ”₯ HEATING SYSTEM PREP

🌑️ HVAC TLC

  • Schedule furnace maintenance - Don't wait until October when everyone else calls

  • Replace air filters - Start fresh for heating season

  • Check heat pump - Clean outdoor unit and clear debris

πŸ”₯ Fireplace & Chimney

  • Test fireplace damper - Make sure it opens and closes properly

🌊 WATER SYSTEMS

  • Check hot water heater - Flush it if you haven't in a while

  • Test sump pump - Hurricane season isn't over yet!

⚑ ENERGY EFFICIENCY

  • Check screens and vents - Make sure they're intact

  • Store firewood away from house - At least 20 feet if possible

  • Clean up fallen fruit - Don't give pests free food

🏠 INDOOR TASKS

🧽 Indoor Prep

  • Deep clean before you're stuck inside - Get it done while weather's nice

  • Test smoke and CO detectors - Change batteries if needed

  • Organize closets - Time to swap summer/winter clothes

  • Check indoor plants - They'll need different care as light changes

πŸ”§ Tool Time
