Shining Cleaning Services clean inside and outside of the window; we scrubbed with soap & water. On residential homes our average time depends on size and number of windows. Quality takes time! Our height limit is up to 2 stories. Shining Cleaning Services clean gutters and downspouts. We recommend cleaning your gutters at least twice a year - once in the late spring and once in the late summer/early fall to avoid debris-clogged gutters that can cause a leaky roof or water damage to the interior or exterior of your home.
