Generate a Home Maintenance Schedule for the Year

Home jobs are easy to ignore until the gutter overflows or the boiler dies in January. This builds a seasonal calendar: boiler service and gutters in spring, fences and exterior work in summer, bleeding radiators and checking the roof in autumn. A realistic list a busy person can keep, not a fantasy of constant upkeep.
