Denver Seasonal Home Maintenance Calendar
A practical, season-by-season checklist for keeping a Denver-area home organized, documented, and ready for weather changes. Print it, share it with a homeowner, or add the recurring items to a calendar.
Designed for homeowners, real estate professionals, home inspectors, HOA teams, and neighborhood resource libraries.
January to March: Winter checks
- Locate the main water shutoff and confirm everyone in the household knows where it is.
- Inspect vulnerable pipes near exterior walls, crawl spaces, garages, and unheated rooms.
- Replace or clean the HVAC filter according to the equipment manufacturer's schedule.
- Check bathroom and kitchen caulk for gaps that can admit moisture.
- Test smoke and carbon monoxide alarms using the manufacturer's instructions.
- Choose one mild, dry day for entryway, baseboard, and window-track cleaning.
April to June: Spring reset
- Check the roof, gutters, downspouts, and exterior drainage after winter weather.
- Inspect screens, weatherstripping, and exterior door seals before opening windows regularly.
- Check irrigation components for visible leaks before starting a normal schedule.
- Clean refrigerator coils and the dryer vent using the appliance instructions.
- Wash high-touch walls, doors, trim, and cabinet fronts that collected winter buildup.
- Create a small repair list before summer travel or home-sale activity begins.
July to September: Summer upkeep
- Review current Denver Water rules before changing an outdoor watering schedule.
- Look for water staining around sinks, toilets, appliances, ceilings, and basement walls.
- Vacuum return vents and confirm furniture is not blocking airflow.
- Clean window tracks, patio-door tracks, and exterior entry thresholds.
- Photograph and address small exterior cracks or seal failures before cold weather.
- Schedule fall furnace service if recommended by the equipment manufacturer.
October to December: Freeze preparation
- Turn off and drain irrigation before the first freeze, following the system installer's process.
- Disconnect and drain garden hoses, outdoor faucets, and seasonal water equipment.
- Clear roof drainage paths after leaves fall and inspect for loose or damaged components.
- Check door sweeps and weatherstripping for cold-air gaps.
- Deep-clean the kitchen before holiday cooking and clean behind movable appliances safely.
- Document unfinished repairs and contractor contacts before year-end.
Details that prevent last-minute problems
Keep one home record with appliance model numbers, filter sizes, warranty dates, contractor information, and before-and-after photos.
Use the season as the reminder, not a fixed weather prediction. Denver conditions vary, so complete weather-sensitive work before the risk arrives.
When a task involves gas, electricity, roofs, ladders, plumbing, or pressurized irrigation, use a qualified professional when appropriate.
