Skylight Cleaning

Holencik Exteriors can clean most of  your skylights while we are cleaning out your gutters. There are some skylights that will require more equipment to insure the safety of our workers and that your skylights and roofing do not get damaged.

The guidelines below are courtesy of Velux Skylights.


  • Skylights are typically installed out of reach, therefore it is assumed that ladders scaffolding or other equipment is being used to reach elevated places during maintenance and inspection.
  • Follow all equipment manufacture’s instructions for safe operation.
  • Use fall protection when applicable.
  • Know your safe working limits.
  • Falls from heights can result in serious injury or death.


Glass Cleaning

  • For best results avoid cleaning skylight during the hottest part of the day.
  • If there are multiple rows of skylights, start at the highest row and work down.
  • Begin by soaking the skylight glass with a clean water and soap solution loosening dirt and debris.
  • Next use a mild, non-abrasive glass cleaner along with a soft brush or other non-abrasive applicator to clean the glass.
  • The cleaning solution should immediately be removed with a squeegee or lint free cloth.
  • Use care not to touch any metal parts of the cleaning equipment to the glass or let any abrasive materials be dragged across the glass surface.

  • Do not use metal scrapers, blades or knives for cleaning large areas of glass as this practice can easily scratch and cause permanent damage to the skylight glass.
  • Scratches or damages to the glass as a result of scraping are not covered under any VELUX warranty.
  • For hard to remove spots like tree sap, label adhesive, paint or other construction material, a new 1” razor blade may need to be used on small spots only.
  • If a razor blade needs to be used, scrape only in one direction.
  • Back and forth scraping can trap abrasive materials under the blade causing scratches and possible permanent damage to the glass.
  • Cleaning your skylight as dirt appears will help prevent the use of scrapers.
