Annual Home Maintenance Checklist to Keep Your Property Value Up

The Sanderson Group March 17, 2025


Regular home maintenance is key to preserving property value and avoiding costly repairs, yet many homeowners overlook essential upkeep until problems arise. A well-maintained home not only enhances comfort and efficiency but also appeals to future buyers should you ever decide to sell. By following a structured home maintenance checklist, Pasadena homeowners can protect their investments, keep their property in top condition, and prevent minor issues from turning into expensive repairs.

Spring: Refresh and Inspect

Spring is the ideal time to assess any damage from winter and prepare the home for warmer months. A thorough inspection and a few key updates can help prevent future repairs and improve overall efficiency.

Inspect the Roof and Gutters

Winter rain and wind can loosen shingles, clog gutters, and create potential leaks. Inspecting the roof for missing or damaged shingles and clearing gutters of leaves and debris ensures proper drainage. This simple maintenance step prevents water damage to the home’s foundation and exterior walls. If there are signs of wear, scheduling professional repairs early can help avoid more extensive issues later in the year.

HVAC System Maintenance

A well-functioning heating, ventilation, and air conditioning (HVAC) system is essential for Pasadena’s warm summers. Replacing air filters, cleaning vents, and scheduling a professional HVAC tune-up improve efficiency and ensure the system is ready for increased use. Regular maintenance also extends the unit's lifespan and helps lower energy costs.

Check Windows and Doors for Air Leaks

Gaps around windows and doors can let cool air escape, increasing energy costs during Pasadena’s hot summer months. Inspecting and replacing worn weatherstripping or caulking small cracks improves insulation, keeps the home comfortable, and reduces strain on the HVAC system.

Test and Adjust the Irrigation System

A properly functioning irrigation system keeps landscaping healthy while conserving water. Checking for leaky sprinkler heads, misaligned nozzles, and clogged drip irrigation lines ensures efficient watering. Adjusting the schedule for warmer months helps prevent overwatering and keeps plants thriving without wasting resources.

Summer: Outdoor Upkeep and Energy Efficiency Checks

With longer daylight hours, summer is a great time to focus on exterior maintenance and energy efficiency improvements.

Paint and Seal Exterior Surfaces

Prolonged sun exposure can cause paint to fade and wood surfaces to dry out. Repainting or sealing siding, fences, and decks protects against moisture damage and extends the life of exterior materials. A fresh coat of paint not only enhances curb appeal but also serves as a protective barrier against the elements.

Inspect and Clean Outdoor Living Spaces

Outdoor spaces, including patios, decks, and driveways, require routine maintenance to stay in good condition. Power washing surfaces removes dirt and mildew while inspecting for cracks or loose boards prevents hazards. Checking outdoor furniture for wear and making small repairs ensures these spaces remain functional and inviting.

Service Water Heaters and Plumbing Fixtures

Draining and flushing the water heater helps remove sediment buildup, improving efficiency and extending the system’s lifespan. Checking for leaks under sinks, around toilets, and in outdoor spigots prevents water waste and potential damage. In older Pasadena homes, updating plumbing fixtures to low-flow models can also reduce water usage without sacrificing performance.

Fall: Prepare for Cooler Months

As temperatures begin to drop, fall is the perfect time to prepare the home for winter and address any lingering maintenance tasks.

Clean and Inspect Fireplaces and Chimneys

Even in Pasadena’s mild winters, fireplaces and chimneys should be inspected and cleaned before use. Removing built-up soot and checking for cracks or blockages improves efficiency and prevents potential fire hazards. Gas fireplaces should also be checked for leaks and tested to ensure they function properly.

Seal Driveway Cracks and Inspect Walkways

Concrete driveways and walkways can develop cracks over time, which may worsen with seasonal temperature changes. Sealing small cracks prevents water from seeping in and causing further damage. Ensuring that paths and stairs are in good condition also reduces tripping hazards, making outdoor areas safer.

Check Insulation and Weatherproofing

Even though winters in Pasadena are mild, proper insulation helps maintain indoor comfort and reduce heating costs. Inspecting attic insulation, sealing gaps around windows and doors, and checking weatherstripping ensures that heat stays inside when temperatures drop.

Winter: Indoor Maintenance and Safety Checks

Winter is a good time to focus on interior maintenance, ensuring that major systems continue running efficiently while keeping the home safe and comfortable.

Test Smoke and Carbon Monoxide Detectors

Regularly testing smoke alarms and carbon monoxide detectors ensures they function properly in case of an emergency. Replacing batteries and checking expiration dates keeps these devices in working order.

Deep Clean and Declutter

Colder months provide an opportunity to tackle indoor cleaning projects such as deep-cleaning carpets, dusting ceiling fans, and organizing storage spaces. Decluttering areas like closets, garages, and pantries make the home feel more spacious and prevent unnecessary accumulation of items.

Inspect Electrical Systems

Checking outlets, extension cords, and circuit breakers for signs of wear helps prevent electrical issues. If lights flicker or breakers frequently trip, having a professional inspect the system ensures safety and reliability.

Year-Round Maintenance Tips

Some home maintenance tasks should be done regularly throughout the year to keep the property in top shape. Staying on top of these small but essential tasks helps prevent costly repairs and keeps the home running efficiently.

  • Lawn and Landscaping Care – Regular mowing, trimming, and seasonal planting enhance curb appeal and prevent overgrown vegetation from damaging the home’s exterior. Keeping trees and shrubs well-maintained also reduces the risk of branches interfering with power lines or damaging the roof.
  • Pest Prevention – Inspecting for signs of rodents, termites, and other pests helps catch infestations early before they cause structural damage. Sealing cracks, storing food properly, and scheduling routine pest control treatments can further protect the home from unwanted visitors.
  • Gutter Cleaning – Keeping gutters clear throughout the year prevents clogs and ensures proper drainage. Regular cleaning helps direct rainwater away from the foundation, reducing the risk of erosion, leaks, and water damage.
  • Appliance Maintenance – Regularly cleaning refrigerator coils, checking dishwasher seals, and servicing major appliances helps extend their lifespan and maintain efficiency. Additionally, performing routine checks on HVAC systems, water heaters, and laundry machines ensures they operate smoothly and prevent unexpected breakdowns.
