Foggy Glass? You Don't Need A New Window.


Fogged Window
Fogged windows can be a real... nuisance (no bad puns today).   Fogged glass makes windows look constantly dirty, and some windows get so cloudy that you can't even see through them.  These windows will also have a lower insulating value, but not by much.  While replacing the window is usually most people's first instinct, this isn't always the best approach.  A couple other options would to replace just the pane or have the window serviced to make it look clean again.


Replace The Pane
Rather than replacing the entire window, you can replace just the defective pane.  Most newer double-hung windows have sashes that can be easily removed without any tools.  Major manufacturers such as PellaAnderson, and Marvin all have 20 year warranties on their glass.  If a window less than 20 years old develops foggy glass, contact the manufacturer.  If the window is older than 20 years, you can still replace the pane for less money than it would cost to rip out and replace the window, but you'll need a window specialist to do the work.

Service The Pane
Some window repair companies, such as Window Medics, will repair alter windows with broken seals to make them look good again.  This process consists of drilling a couple tiny holes in the glass, washing out the inside of the window panes to clean up the 'fogginess', and then installing tiny vents in the holes to allow the window to breath.  The window will no longer be foggy, and it will stay clean.  The downside to this repair is that the window will have a slightly lower insulating value than it had before the glass fogged over, but this will cost much less than replacing the window.

I've worked with a company for a while that does the repair to remove fog. From what I've been told the fog can be removed, if caught early on, but if you have the water streaks it's past the point of that type of repair. Even so being able to replace a single pane is an excellent option.

Any idea on what the cost difference, "replacement of the pane versus the fog "abatement" approach is?

Vince - I've heard the same thing about the bad streaks.

Harold - I've never price shopped replacement panes from the 3 major manufacturers that I  listed in my blog, but I have shopped prices from American Craftsman (Home Depot's vinyl window).  They charge 1/3 the price of the window for a new sash on a double-hung window.  The fog abatement costs about 1/3 to 1/2 the price of a replacement window.  A new sash is clearly the best option if it's an easy replacement.

Some can even be done yourself for quite a bit less.

In additon, some of the panes (such as the tilt-outs) can be removed and taken to the glass store to be done there.  Again more economical than having the glass guy come to the house.

I'm not keen on the cleaning as it removes a bit of the insulating value.

Hi Reuben good post. Very useful information. I have been telling my clients this for quite some time but as you stated most feel the window should be replaced right away. Also, I referred a deck inspection your way in the metro area on Monday, I believe Maple Grove. Hopefully he books with you. Figured I'd send the work to a fellow good inspector. Keep posting good info Reuben.

Erby - very true.

Randy - Thank you for the referral, much appreciated!  I scheduled the deck inspection for Friday.

I have seen the "fix" to the foggy glass and it works very well. It is a real cost saver for folks on a tight budget. Thanks for reminding me that this option is available, I haven't seen it used for a while.

And I'm all out of Windex this morning. I shall put it on my grocery list for later today.

Great post, Reuben.

Thanks.  I always said to replace but I guess alternatives could work.

Russel - thanks for reading!

Gene - replacement is a great option if the windows are all going to be replaced soon.

Reuben another side note regarding the cleaning method---it can only be done on windows that are not tempered glass. and also that don't have the intercept type spacers.
