The short answer
Follow the manufacturer’s maintenance instructions, inspect the home regularly, and report warranty problems promptly.
Keep good records
Save contracts, warranties, manuals, photos, inspection reports, and repair requests. Use qualified professionals for structural, electrical, plumbing, HVAC, roofing, and installation-related work.
Use the manuals to build your schedule
Keep the home manual and equipment manuals together, including information for heating and cooling, appliances, and any site-installed systems. Use their schedules and product instructions rather than one generic maintenance list.
Record the date and location of a leak, sticking door, unusual movement, or other change, with photos when safe. That gives the service professional a starting point. Do not attempt electrical, structural, or support adjustments simply because the problem looks small.
Make the service record easy to use
Keep one folder with a dated list of concerns, photographs, service appointments, and completed repairs. Identify the room or outside location each time, especially when several similar items need attention. After work is completed, note what was done and retain the work order. The punch-list workbook below can help organize observations without turning them into a diagnosis or a do-it-yourself repair instruction.
