HouseYears Puts a House on a 200-Year Clock

Field notes

The site uses a shared 0–200-year visual scale to separate typical service life from the warranty language attached to a product. Its examples expose the mismatch clearly: pressure-treated decking is listed at roughly 15 years against a conditional “lifetime” warranty, while solid hardwood is listed at 100+ years against a 50-year warranty. The index spans household systems from roofing and fencing to septic tanks, ductwork, insulation, and smoke alarms.
