Make Prevention Painless: Your Simple Maintenance Plan

Now that you know which small fixes deliver big protection, how do you make sure they actually get done?

Here's a simple 3-step approach:

1. Schedule quarterly "home check-ups" — Mark your calendar for just 2-3 hours every three months to tackle preventive maintenance
2. Create a seasonal checklist — Different seasons require different maintenance focus areas or use ours [Winter, Spring, Summer, Fall]
3. Document your work — Keep records of when you last performed each task
