How to Window Cleaning (Interior)

Clean windows brighten your home significantly—dirty glass can reduce natural light by 20-40%—and window cleaning also provides an opportunity to inspect for problems. This maintenance task involves cleaning interior glass surfaces, vacuuming tracks and sills where dirt accumulates, checking screens, and looking for signs of seal failure or condensation between panes. Beyond aesthetics, regular window cleaning helps you catch developing issues like failed seals, rotting frames, or broken hardware before they become major repairs.
