A. If the window has a light haze or constant dripping moisture we can often clean them out. If there is crystallization, prominent streaks ("river-bedding") or white water spots that have dried in the sun, they may fade, but we usually will not be able to clean them out completely.

A: There is no exact answer to how long it takes for a window to clear. There are a three major variables; how large is the window, what is the window orientation to the sun and how much moisture is in the window system. Triple pane windows take longer due to the fact there is twice the area to dry out. Honestly most windows look worse when we finish than before we started because the cleaning and rinsing process adds moisture to the system. However now the window can begin to heal or dry out. In the summer many windows dry out in two weeks. In the early spring and late fall they may take 6 to 8 weeks or more to completely dry out. Our warranty guarantees that all moisture will be evaporated after 12 weeks.

A: Generally speaking, in a standard thermal pane, the R value is in a range of 2.5 to 4.3. The R value of the thermal pane will be restored very close to the original R value of a new unit when the unit is dried out.

A. Sometimes. There are two major types of low-e coated windows: soft coat and hard coat. Soft coat low-e windows are very delicate metallic coatings that easily oxidize. We cannot repair low-e windows that have started to oxidize. However some windows have a more durable coating. With hard coat low-e windows the coating is baked on and is much more resistant to moisture and we often can restore those. As with all our services, a technician will have to asses each window.

A: No, normal window cleaning will not affect our process. You should try to avoid putting harsh chemicals directly on the vents and DO NOT high pressure spray. We suggest covering up the vents when possible.

A: The access holes are discreetly positioned in the corners of the insulated glass unit and generally out of the way of the main window viewing area. In fact the upper hole and vent are generally covered by blinds or drapes and not seen. Most clients are very happy with the dramatic increase in the main view area once we have removed the condensation and the small access holes and vents almost disappear.

A: With regard to the argon issue, while we concede that argon has many very good qualities (i.e. it deadens sound and has better insulation value that regular air), in our opinion, the argon has been out of a failed window unit for a considerable period of time before condensation formed in the window. So the best that we are able to do is return the R value to what an original air fill window would have been, slightly less than an argon filled window but considerably better that a window filled with wet air.

A. No, we don't . The defogging process re-engineers your window to breathe so that moisture can't continue to accumulate.
