We have two ways to defog your windows and restore your view.

Glass Replacement

Glass replacement is different than window replacement. Glass replacement utilizes your existing window frames. Only the glass unit is replaced so there is no construction or painting involved. To request a free quote contact us.

      Pros
  • Cheaper than window replacement
  • Instant results
  • Can be done to any type of window
  • You can upgrade to low-E, Argon, grids, tempered glass, or designer glass
      Cons
  • More expensive than window defogging
  • Doesn't upgrade your window frames

Window Defogging

Window Defogging repairs your existing failed window. We don't replace either the frames or the glass in this process.

      Pros
  • Cheaper than glass replacement
  • No repainting even with wood framed windows
  • Excellent for Weathervane wood framed windows
      Cons
  • Not an instant fix. Can take 4 to 12 weeks for the window to fully defog
  • Not effective on vinyl framed windows
  • Can't be used on tempered glass
  • Not effective in windows that have been failed more than 12 months
  • Valve visible in window after defogging

The Window Defogging Process

First, we drill two tiny holes (2mm) in the glass window pane, one in an upper corner and one diagonally opposite it in a lower corner. Next, we spray several proprietary and environmentally friendly solutions inside the sealed window unit to clean and remove all haze and contaminants. We then extract the solutions and dry out the double pane window. Finally, we apply our patented, micro-valves to the holes we drilled.

The Window Defoggers Process

Due to the water already present in the desiccant and inner frame, along with the solutions we used in cleaning the thermal pane window, it can take up to 12 weeks for the window unit to completely dry. In the summer months when we have lots of sun we find that windows usually dry out in two to four weeks. During this healing process, expect to see moisture or fog come and go repeatedly. This is normal! Sometimes, in order to speed up the drying process here in the humid Northwest, we will wait to apply the valves until two weeks after the service.

Congratulations! Your insulated glass units (IGUs) have been re-engineered and will now enjoy years of extended life. You’ve saved money, kept tons of glass out of the landfill, and restored the R-value of your windows back to their original specifications.*

Now you understand how we can fix your foggy windows.

Back to Learn why windows fail

Window Defoggers process has been healing windows since 1989. We back our repairs with a full 10-Year Limited Warranty.

*A few high-end windows may have been filled with Argon, or another inert gas that, when present provided a slightly higher insulating value.
