Having misted and foggy double glazed windows can be unsightly in the home; but this does not have to be the case because nowadays, it is easy to repair double glazed units. Double glazed windows becoming misty and fogged up is not an unusual occurrence when the guarantee on the windows have expired.
The double glazing unit usually comes in three different parts, mainly the window frame, the window sill and the glass. When the units are ordered, the parts arrive individually with the beads remaining in the frame so that it is apparent how to join them.
The two layers of glass are kept apart by a separator that has hundreds of minute balls that are made of silica. The balls are placed there to avoid condensation by soaking up any dampness that may exist in between the layers of glass. The misting and fogging of the double glazing usually happens when the silica becomes soaked with moisture. Although most of the double glazing companies offer a guarantee for ten years, this should not occur during the first five years. When the double glazing unit is purchased there should be a receipt that says the company from which the unit was purchased will safeguard the units from breaking down.
The formation of water droplets and misting in the unit is not unusual if it is an old unit, and especially so if the unit has passed its warranty period. If this occurs before the expiry of the warranty, then the unit must be replaced by the selling company.
Nowadays, it is easy to repair double glazed units. This can be done by drilling a tiny hole in the glass—usually done from the outside—and then inserting a vent. This has to be done by a specialist with the necessary equipment. It is something that would be worth looking into because most companies state that the cost to repair double glazed units cost half the price of a replacement unit.
If the home in which the double glazing is to be repaired had been purchased with the double glazing installed, it is going to be slightly more difficult. Having to work out the manufacturer and determining the age of the unit is going to be virtually impossible as there isn’t usually a requirement for such information to be incorporated onto the unit.
There are specialists who deal in repairing double glazing units and they usually have the usual replacement parts required to repair the window. However, it is not unusual for homeowners who have windows that are older than they had assumed them to be, which means the model may no longer exists hence the parts not being available.
In these circumstances it is impossible to repair double glazed units, but one would have to look into choosing a replacement unit. There are installers who carry out replacement work at a very low cost. Hence, it would be a good idea to shop around for quotations on replacement windows.
