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 our simple 3-step approach:
- Schedule quarterly "home check-ups" — Mark your calendar for just 2-3 hours every three months to tackle preventive maintenance
- Plan your seasonal checklist — Different seasons require different maintenance focus areas (Spring, Summer, Fall, Winter)
- Document your work — Keep records of when you last performed each task
At Hauser, we've built technology that automatically reminds you when it's time for critical maintenance tasks, but even a simple spreadsheet can make a world of difference.
