How do you get rid of condensation between double-pane windows?
You cannot clean it out, because it is not on a surface you can reach. Condensation between the panes means the seal on the insulated unit has failed and moisture is now inside the sealed cavity. The fix is a new insulated glass unit in the same frame. Defogging services drill and vent the unit, which clears the view but does not restore the seal or the insulating gas.
Will condensation between window panes go away on its own?
No. It may look better on a dry day and worse on a humid one, which fools people into thinking it is clearing, but a failed seal does not reseal itself. Once moisture is in the cavity the unit will keep fogging and the deposits gradually etch the inside of the glass permanently.
Can a foggy double pane window be repaired, or does it need replacing?
The glass unit is replaced, the window is not. The insulated unit comes out of the existing frame and a new one goes in, so you keep the frame, the sash and the hardware. That is a fraction of the cost of a full window replacement, and it is the right answer whenever the frame itself is still sound.
Can you replace just one pane of glass in a window?
Yes, if it is a true multi-pane window with separate glazed openings. If the divisions are decorative grilles sandwiched inside one insulated unit, which is how most modern windows are built, the whole unit is replaced because the grille is sealed inside it. We can tell which you have from the outside.
How much does a single pane of glass cost to replace?
Reglazing an existing frame is the cheaper case, and it applies whenever the frame is sound. Single pane is the cheapest case; an insulated unit costs more because it is two panes, a spacer and a sealed cavity, and tempered costs more again because it has to be tempered after cutting. Size drives all three.
Does replacement window glass have to be tempered?
In some locations, yes, and it is not optional. Code requires safety glazing near doors, at the bottom of stairs, in and around tubs and showers, and in large panes close to the floor. We check the location against the code before ordering, because putting annealed glass in a hazardous location is a failed inspection and a liability.
How long does it take to get a replacement insulated glass unit?
Usually a few days, because insulated and tempered units are fabricated to your measurements rather than pulled off a shelf. We measure, order, then fit. If the opening is broken out rather than just fogged, we board it the same day you call so the building is secure while the unit is made.
